it will protect them from tampering

if JWT Token will be not decoded back with your secret key, then it was tampered or expired

You can delete his cookie immediately with request sent to server about room deleting

[lime frigate]

Okayyy i will definitely try it

Thanks for the info mate

[inland oak]

u a welcome

xD, the problem was solved with just having stuff client side

no delay between requests = no problem

there will be still micro delay though, since stuff in client browser is launched in async mode

but that should be not an issue

Any suggestions on a good hosting provider? (To host django api or app)

[manic crane]

AWS

[rotund perch]

But ive saw some reviews complain s that its hard to setup

[manic crane]

hmm same but i dont mind a bit of tutorials to show my way round cause i heard its really good

[rotund perch]

Okay thanks for the suggestion!

[manic crane]

no problem

[eternal blade]

You will have to save the user input and iterate over it in the html and display the data

[worthy oar]

@rotund perch asc wr wb

[opaque rivet]

@rotund perch do you just need a RDP?

[rotund perch]

is that a hosting method? Whats the diff between it and the other hosting methods

[opaque rivet]

No diff

[rotund perch]

I mean like performance

[rotund perch]

Anyways if thats a good method, I dont mind suggesting me some providers

[opaque rivet]

I use AWS but if you just want an RDP there are cheaper providers

Like hetzner or DO

[fossil pond]

Hello guys. So I changed my html file to have a lot of blocks to make it easy to read. But the only thing that's running is the loading screen in an infinite loop. What's surprising is the fact that even when I comment out the loading screen div the only thing that appears is the loading screen and not the actual webpage.

{% load static %}

{% block title %} 
    Rhitam's Website 
{% endblock %}

{% block content %} 
    {% include 'welcome-content.html' %} 
{% endblock %}

<!-- {% block container %}
    <div class="loader-wrapper">
        <div class="loader">
            <div class="image">
                <i class="fa fa-dumbbell"></i>
            </div>
            <span></span>
        </div>
    </div>
{% endblock %} -->

{% block javascript %} 
    <script src="{% static 'main/welcome/base.js' %}"></script> 
{% endblock %}```

base.html doesn't even have the javascript

even when I comment out the entire js the same thing happens

[fossil pond]

Any help is appreciated! I'm having to put repetitive html codes on every webpage because of this.

[opaque rivet]

base.html doesn't have JS but you're extending it and adding JS to it:

{% block javascript %} 
    <script src="{% static 'main/welcome/base.js' %}"></script> 
{% endblock %}

[fossil pond]

Yeah even when I comment this out I get the same output :/

[opaque rivet]

maybe the webpage is cached then?

[fossil pond]

no used a diff browser and the same thing happens

[opaque rivet]

does welcome-content.html have any JS

Two additional questions. Did you do a hard-reset of the cache? (ctrl+F5)
Did you try incognito/private mode?
Just questions to rule out caching absolutely.

[ionic raft]

Hello @dusk portal I can try 🙂

[dusk portal]

u know web scraping

[ionic raft]

Very little. I worked briefly with Beautiful Soul and Selenium about 3-4 months ago. I am very rusty and would be surprised if I could help with complex troubleshooting.

[dusk portal]

I wanna scrape Udemy Courses by some data which user will enter in my form

[ionic raft]

Well, I would start by checking their terms of service for such scraping. When a paid service doesn't have an API, going to web scraping can be legally problematic.
That said, if you are looking to scrape what courses are available, my sense would be that Selenium may be a good starting point.
IIRC you can also check the URL with the path robot (specifics for you to research) to see what scraping Udemy allows.

[dusk portal]

I'm in a hackathon

They have a docs too

But ig for me hard to follow

https://www.udemy.com/developers/affiliate/

[grim seal]

Anyone here familiar with the Pyramid framework and it's official Quick Tutorial? I've reached a step in the tutorial where suddenly none of my code runs, with the last error in the traceback being: ModuleNotFoundError: No module named 'tutorial'. This after successfully completing each step of the tutorial up until my PC crashed. Now none of my tutorial code runs, and I'm hoping that someone knows the tutorial because otherwise it's one hell of a lot of coding to show here

[calm plume]

What are you looking for? What type of data?

Their API provides a decent bit of information

Also, scraping them Udemy is a violation of their robots.txt: https://www.udemy.com/robots.txt. They only allow things like that on their /api-2.0/ route, which you'd be better off just using through traditional REST API interaction methods.

[ionic raft]

That is not surprising at all.

OMG... 😄
So, you know when you've been trying to find out why you can't get the pk from the get_context_data function in the view, and then a couple of hours later you realize you built the url for the CreateView WITHOUT passing a pk over?
Yeah...that.
😄

[dusk portal]

so i cant scrape courses link with title to give like a roadmap as it's our hackathon task

[mild marsh]

[native tide]

anyone knows how to make firefox in dark mode

[worthy lake]

if I had to guess i would say modifying userChrome.css

https://www.userchrome.org/

[ionic raft]

As was suggested, I'd check https://www.udemy.com/robots.txt to check what they allow. If you try to scrape in contradiction to their robot.txt it is an illegal activity. If you're engaging in an activity with a hackathon that is asking you to engage in such activity I would suggest considering another activity.

In short, I expect that a paid service like Udemy wants you to use their API. They get control over the data exchange that way and everyone is happy (and behaving in a legally acceptable manner).

Web scraping is filled with ethical grey areas and no-goes.

[opaque rivet]

Who is ever going to enforce webscraping? It's impossible.

ok someone please help

im trying to hyperlink the word accommodations to the id tag "faq13" but its not working

the word is clickable but it takes you nowhere

what am i doing wrong?

[tawny pollen]

Get the metadata for the required field and use it to query the required field data
what does "query" mean ? this is django. thanks.

[ionic raft]

I am not completely clear on what you're asking for. But, when you use an <a> anchor tag in html for an in-page hyperlink you need two parts to it. If on the other hand, you're trying to create a link outside the site, then the href value you have is not going to work.

An in-page anchor tag should have two parts. This first anchor tag is the clickable link:

<li><a class="heading-link" href="#1-Introduction">Introduction</a></li>```
This second part is where the above link will take you to in-page:
```html
 <h3 class="heading-link"><a id="1-Introduction">1. Introduction</a></h3>```
As a rule, posting screenshots for code is not very helpful. It is much better to post the code in markdown style, with back-ticks.

!code

[lavish prism]

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

These are backticks, not quotes. Check this out if you can't find the backtick key.

[ionic raft]

As a side note, I just released v0.3.0 of LanesFlow. There's now an hour tracker 🙂

There are two options. You can either track hours for a pool of prepaid hours for the client organization, or you can go with billable hours. This is the prepaid hours option in play.

I think this needs a few filters....But otherwise, I welcome any thoughts. If anyone has experience with this sort of thing and has feedback, please share.

im still confused about this can i pm you?

I'd prefer not to DM troubleshooting. All benefit by keeping it here

Use three backticks...

<h2 id="faq13">I am looking for accommodation for the event, where is best to stay?</h2>

<a href="#faq13">accommodations</a>

first line is on my FAQ page, second line is on the home page

[regal fossil]

Video is already stored
Url is media/videoname.mp4

I want to send that video to google translate api so i need full path i think?

[spice spindle]

im trying to link the word accommodations to the id=faq13 on the FAQ page

[ionic raft]

I would use a CharField in the model to store the raw url. I'd review API to ensure I'm sending it according to their guidelines.

[ionic raft]

Take a look again at your code and the snippet I've provided. If I solve this problem for you you won't gain the most learning from it. You've missed something in the id tag

[spice spindle]

I think what your talking about is class="heading-link"

but I don't know what I would put there in my case

[ionic raft]

No. Take a look at the beginning of the tag...you have id...but where is a?

[spice spindle]

sorry I'm like 3 weeks into coding

[ionic raft]

It's all good. The receiving tag is not an anchor. It's missing the <a...

[spice spindle]

oh

ok let me try it

[ionic raft]

Like I said, look at what I posted.
Sorry for the inclusion of the css class. That was distracting

[spice spindle]

<h2> <a id="faq13"></a>

still didn't work

[ionic raft]

Can you post your code...and please NOT screenshots

[spice spindle]

i dont know how to

[ionic raft]

Do you know how to select text and copy/paste?

Just copy the two tags...not the whole html file

I'm going to type them up the way I'd do it...give me a minute...

[spice spindle]

i have been copy and pasting

[ionic raft]

<a href="#faq13">accommodations</a>

<a id="faq13">I am looking for accommodation for the event, where is best to stay?</a>```

[spice spindle]

i have that exactly and it wont workl

[ionic raft]

Then I can guarantee you you're missing something. I have that exact layout working for me.

[ionic raft]

Coding is very meticulous. I've spent 2 days trying to find errors such as : instead of =

[spice spindle]

does it matter if it is linking from the homepage to a FAQ page

[ionic raft]

This is why you need to post your code. I can't help you unless you work that out.

I suggest you work out how to read the following along with copy/paste

!code

[lavish prism]

Here's how to format Python code on Discord:

```py

OOooooooo. YES. That's another page. Then you need the URL for that page

#❓｜how-to-get-help

Also, I suggest you study the art of asking a good question. Seriously. If you want help from other programmers you're going to want to learn this:
https://pythondiscord.com/pages/guides/pydis-guides/asking-good-questions/

Ok. I've got to go to bed. Best of luck. I know you'll get there....

[spice spindle]

finally got it

thank you for real, i spent hours trying to figure this out

[ionic raft]

Once I worked out you were trying to get to another page, that showed why it wasn't working.
On the plus side, you now know about in page links as well as links to other pages 🙂

On a completely side note, I just got my web application emailing out html emails when events happen 😄

I have to say, seeing a polished email arriving from an automated web application like that...makes my heart very happy 🙂

Thank goodness for CONST variables 😄

How can I filter on the basis of queryset of foreign key in Django ??

(django) i have a order model and i have thought of adding datetime fields placed paid dispatched delivered can you suggest me improvement to the model?

what are the stages of an order?

[ionic raft]

The stages you've listed cover the core steps. But an ordering process will vary by business depending on controls, etc.

[cerulean badge]

yes its just a personal project and i want it to be universal. placed field gets a datetime when the user checks out, do you have any idea about adding a field so indicate the order is being worked on?

[ionic raft]

I've been working with processes as a business analyst/consultant for 25+ years. There is no such thing as a "universal process".
I would add order_status = models.CharField(choices=ORDER_STATUS_CHOICES, default='1) Order placed')
That is from memory, so check syntax....
You should create a CONST tuple at the start of the file for ORDER_STATUS_CHOICES...

[cerulean badge]

the fields i mentioned are datetime fields

[ionic raft]

I know. I offered syntax for a choice field.

[cerulean badge]

do you think i should add a field which would mark the order is being worked on?

[cerulean badge]

i have one more question how do i provide the interface for disptached, delivered and paid (in case of cod) in my custom admin dashboard?

[cerulean badge]

how about empty post form with csrf token for dispatched, delivered and paid stages which sets their values?
and showing the form corresponding to current stage?

[native tide]

How can I dynamicly calculate in django, days delta along queryset

[wide canyon]

Is sending an article i wrote on django here against the rules?

[native tide]

haha wouldn't be harmfull : D

mind helping out ?

[wide canyon]

For each row? in the queryset

Annotate should do that i guess

[native tide]

Basicly I have a model with a field, date_to, I wanna calculate how many days are for each item

[wide canyon]

Annotate should work

[native tide]

so i wanna add a field, expires_in_days = date_to - now()

[wide canyon]

ohhhh

[native tide]

yea for example lets asume, item expires on 6.9.2021

i wanna add a field expires_in_days = 1

6.9.2021 - 5.9.2021

etc..

[wide canyon]

can you add it as a class method and call it whenever you need instead?

[native tide]

i cant do order by then haha : D

tought about property

as well

[wide canyon]

I hope I'm not giving bad advice

Annotate and order by annotated field

Unless you want to do it in multiple places

We'd have to think of something more efficient

[native tide]

i need in multiple ...

hmm

even if i do forloop, i cant after that execute order_by

i can by sorted and key

[wide canyon]

found something on SO

Daniel Roseman's solution makes a calculated field an attribute of a Model, however it does not make it accessible via QuerySet methods (eg. .all(), .values()). This is because QuerySet methods call the database directly, circumventing the django Model.

Since QuerySets access the database directly, the solution is to override the Manager's .get_queryset() method by appending your calculated field. The calculated field is created using .annotate(). Finally, you set the objects Manager in your Model to your new Manager.

Here is some code demonstrating this:

models.py

from django.db import Model

class InvoiceManager(models.Manager):
    """QuerySet manager for Invoice class to add non-database fields.

    A @property in the model cannot be used because QuerySets (eg. return
    value from .all()) are directly tied to the database Fields -
    this does not include @property attributes."""

    def get_queryset(self):
        """Overrides the models.Manager method"""
        qs = super(InvoiceManager, self).get_queryset().annotate(link=Concat(Value("<a href='#'>"), 'id', Value('</a>')))
        return qs

class Invoice(models.Model):
    # fields

    # Overridden objects manager
    objects = InvoiceManager()```
Now, you will be able to call .values() or .all() and access the newly calculated link attribute as declared in the Manager.

It would have also been possible to use other functions in .annotate(), such as F().

I believe the attribute would still

basically overriding the default manager

[native tide]

hmm

yea

Already pretty decent with Python, but I’ve decided to rewrite the backend of a personal project in Django (I tried NodeJS first but it just feels like it barely works lol). I’ve never used it before, but have been interested for a while since I like using Python in general. What’s the best tutorials you guys know of for building APIs with Django?

[native tide]

Two scopes of django

its a book, highly recommend

includes best practices and good explanation

[velvet yew]

How can I make custom responses for Django REST framework's authentication? I'd like to replace {'detail': 'Authentication credentials were not provided.'} and {'detail': 'Invalid username/password.'} etc. with custom responses

[broken mulch]

can my frontend React app establish a websocket connection to my backend django server?

if so, how would I open the websocket client and what library would I use in React?

pls ping on answer

I just need the libraries and their source / docs

[opaque rivet]

django channels

[opaque rivet]

modify the middleware

[velvet yew]

What would be a simple solution to do so? Without modifying stuff in the original files obviously

[ancient obsidian]

Django or Flask? Which one should I use?

[opaque rivet]

Not sure... (without modifying the original file). Maybe you can find the middleware class, make a new middleware which inherits from it, and find a way to modify the response message. Then apply that custom middleware instead of the one provided by DRF.

[opaque rivet]

Django if you want quick development due to its battery-included nature. Flask if you want more freedom to develop exactly to your own specs.

[velvet yew]

Sounds like a plan, I'll try, thanks

[ionic raft]

It's funny how that works. I found out the hard way the difference between a browser reset and a hard-reset. And even then, incognito can sometimes be the only way to get through it. Port numbers for Flask dev was my nemesis when I was coding Flask. If you ran multiple projects and wanted different ports...watch out!

[ionic raft]

I highly recommend two-scoops. I'm still working my way through it. But as my Django experience grows, my ability to make use of that wonderful book grows also.

[native tide]

haha glad we have someone who read/is reading it : )

shoutout to the writers, they did amazing job on it

pure experience and knowledge

read only that book you'll have django in palm 😛

[opaque rivet]

what do we think about the look of this?

thinking to add more contrast.

just spent ages animating it all and adding drag n' drop items. Loving how it's so reactive.

[native tide]

Hey guys,

I've always tried to learn flask and all, I did some goofy things here and there but never got to deploy them.

What's the best way to deploy a flask app ? I always encounter these examples WSGI, but I feel like I don't understand anything and that I have to do more reading about networking and whatnot.

Sometimes I even feel somewhat "scared" and hesitate to read about it.

Does anyone have a good place to start ?

[stray notch]

@fickle basin I think you should check that you are using 4 spaces for each indent

[fickle basin]

it is 4 spaces

it's working after copy/past ?? thats wierd

sublimetext is set on Tab Size : 4

that weird

[stray notch]

maybe it's the 8 spaces on the line before?

[stray notch]

@native tide I found this page helpful in identifying some of the security issues, if that's what you're worried about: https://flask.palletsprojects.com/en/2.0.x/security/

[ionic raft]

I asked around for good books on Django before I started my first Django web app (with an idea I'm excited by). I used it to brush up on some best practices and get pointers. I expect to dip back into it over the years to come. LanesFlow is now some 28,095 total lines of code, with over 10 applications. You could say that Two Scoops has been instrumental in this newbie's journey in Django (didn't know Python Apr 15, 2021, or Django Jul 8, 2021).
And yes, amazing job by the writers...

[ionic raft]

Corey Schafer has some good tutorials. I did go through his Django deployment video. Maybe he has a Flask deployment video too.

[stone flax]

hey all, are there any alternatives to Google Analytics for Flask out there? I'm looking to use a self-hosted alternative, or maybe even considering my own data capture+analytics system storing info from each request from scratch. but that seems a bit too much. I'd much rather leverage an open source solution if there is any

[stray notch]

@stone flax I've been eyeing https://plausible.io, but haven't tried it yet

Can someone help me understand how requests are handled in an ASGI server? What async really does in situations when say 100 people are requesting the server? Does it resolve request one my one? if so then what's the use of it being async? If not how does it serves these requests?

[raven harbor]

guys can someone help me my issue at #help-pineapple

[inland oak]

lets imagine you have on async worker

first user requests the server, and got stuck in a long await operation

during this time I think in theory server supposed to be able to process another user 🤔

I could be wrong though

anyway, multi worker async server exist anyway

so threading can be applied too

to process users in multiple manner

better ask expert in #async-and-concurrency channel

[opaque rivet]

Doesn't WSGI Django use Asyncio to process requests asynchronously though?

[lime mist]

yes that's my main confusion, I don't understand the difference between async request and spinning threads. I made a server that runs OCR on image with an ASYNC server and while it was processing image it didn't accept new connect so I had to implement it so that it receives a request and puts it onto a thread. So I don't understand what ASYNC is suppose to do when it's clearly not working?

[inland oak]

i know for sure only that

ASGI server is needed in order to work with django channels/web sockets to make real time chat

[lime mist]

hmm, I shold take this to #async-and-concurrency . Thanks @inland oak 😄

[inland oak]

those async features confuse me greatly too 😉

I hope there is some good book about them

[lime mist]

I hope so too, it's simple to understand when I implement it from scratch for test but when it comes to working with frameworks like Socket.io that has an ASGI Server. Man I feel completely lost

[opaque rivet]

@lime mist From my knowledge, WSGI applications are functions which take in a request and return a response. So in theory requests are handles synchronously.

The difference with ASGI applications is that it's a callable which is async, and it awaits the response. So the server can handle other requests while the response is being awaited.

My confusion is that django uses asyncio already to handle requests, maybe I need to read about that more.

[inland oak]

it could be using asyncio in order to have a queue of the sync requests too perhaps 🤔
in order to not reject them when server is already busy, and process them in the order they are coming

[lime mist]

As I shared my experience with a project, I was using an ASGI server and still it didn't accept any connection while it was doing OCR on an Await for a request before

[inland oak]

I saw a mention of asyncio being used as job queue at least

[lime mist]

could be but in my experience it rejected the connection after 10 or so seconds because it was still processing 1st req

[inland oak]

library should be async friendly

[opaque rivet]

Asyncio is probably used for async views. But if you use async views in a WSGI server do you even get any benefit? I don't think so, since it's still 1 request at a time.

[inland oak]

it the library is not async friendly, it will not help that it is awaited, because it will still block the thraed

for example, it will not matter if I put Selenium library into async

or if I will use requests library with async

it is not async friendly

I need aiohttp for that

[opaque rivet]

@lime mist what asgi server were you using? Also what's OCR?

[inland oak]

computer vision library

recognizing stuff in images, characters I think

[lime mist]

A minute, let me share my source

[opaque rivet]

Ah okay

[lime mist]

yeah grab test from image, school project 😄

[inland oak]

btw!

starting from python 3.9

you could launch async not friendly processes

in a second thread!

[opaque rivet]

It would be cool connecting a computer vision lib to a CNN to detect images in real time

[lime mist]

import socketio
import json
from helpers import processTextifyRequest

sio = socketio.AsyncServer(async_mode="asgi", cors_allowed_origins="*")
app = socketio.ASGIApp(sio)

online = 0
like = 0


@sio.event
async def connect(sid, environ):
    print(f"[CONNECTED] {sid}")
    global online
    online += 1

    await sio.emit("serverStats", json.dumps({"online": online, "like": like}), to=sid)
    await sio.emit("updateOnline", online)


@sio.event
async def getText(sid, data):
    await processTextifyRequest(sio=sio, sid=sid, data=data)


@sio.event
async def doLike(sid):
    global like
    like += 1
    await sio.emit("updateLike", like)


@sio.event
async def disconnect(sid):
    print(f"[DISCONNECTED] {sid}")
    global online

    online -= 1
    await sio.emit("updateOnline", online)

[inland oak]

thus, making sure that environment remains async friendly

[lime mist]

I'll have to learn more about these

[lime mist]

async def processTextifyRequest(sio, sid, data):
    loop = asyncio.get_running_loop()

    print(f"[REQUEST RECEIVED] {sid}")

    with ProcessPoolExecutor() as pool:
        result = await loop.run_in_executor(pool, getTextFromBase64, data)

        print(f"[PROCESSED] {sid}")

        await sio.emit("text", result, to=sid)

[opaque rivet]

ngl I'm lost with this 🥴 seems like more async / asgi reading is needed

[lime mist]

If I don't do this then the request is served one at a time 😦

[opaque rivet]

What if you use asyncio.gather() somehow to concurrently run coroutines?

I can't really explain it well

But when I was working with async, just awaiting coroutines was just like sync code. I had to use asyncio.gather() etc

[lime mist]

if you are free then maybe you wanna play around and make it work without threads?

how to learn django??

I'm beginner to this

[thorny quartz]

from youtube

[inland oak]

from official docs
https://docs.djangoproject.com/en/3.2/

[unreal bolt]

how to improve this? (forgot to tell its js)

if (item0Inner == p && item1Inner == p && item2Inner == p) return [true, p, item0.id, item1.id, item2.id];
if (item3Inner == p && item4Inner == p && item5Inner == p) return [true, p, item3.id, item4.id, item5.id];
if (item6Inner == p && item7Inner == p && item8Inner == p) return [true, p, item6.id, item7.id, item8.id];

if (item0Inner == p && item3Inner == p && item6Inner == p) return [true, p, item0.id, item3.id, item6.id];
if (item1Inner == p && item4Inner == p && item7Inner == p) return [true, p, item1.id, item4.id, item7.id];
if (item2Inner == p && item5Inner == p && item8Inner == p) return [true, p, item2.id, item5.id, item8.id];

if (item0Inner == p && item4Inner == p && item8Inner == p) return [true, p, item0.id, item4.id, item8.id];
if (item2Inner == p && item4Inner == p && item6Inner == p) return [true, p, item2.id, item4.id, item6.id];```

[native tide]

put them in a tuple

then compare the tuple

[unreal bolt]

i dont even know what a tuple is (,:

[native tide]

i.e. instead of a==1 and b==2

if (a,b) == (1,2)

[unreal bolt]

so would be like:

if ((item0Inner, item1Inner, item2Inner) == p)```?

im trying to understand how it works

[native tide]

== (p,p,p)

in that case

[unreal bolt]

if ((item0Inner, item1Inner, item2Inner) == (p, p, p))```

[native tide]

ye that will work

it's just checking 1 object rather than 3 now.

so reduces the 'ands' and '==' you have to do

[unreal bolt]

hmmm cuz this doesnt exist right?

if (item0Inner == item1Inner == item2Inner == p)

[native tide]

not in python the way you would think. also chaining them can causes issues depending on the type

cos of dunder methods

[unreal bolt]

okay

[vestal hound]

what do you mean?

[native tide]

so there are python magic methods

[vestal hound]

no, I mean, why do you think a == b == c == d won't work?

[native tide]

that tell a type how to * or / or other stuff. depending on what they are next to. and wheter thats on the left or right

[vestal hound]

(in the general case, assuming __eq__ is sensibly defined)

[native tide]

ye sorry. that one probably does work

i was thining of something else

[unreal bolt]

what is the problem?

[vestal hound]

so one nice thing about Python is that you can combine comparison operators

e.g.

[native tide]

but looks shit too compared to comparing tuples IMO

[vestal hound]

!e

print(1 < 3 < 6)
print(1 < 7 < 6)

[lavish prism]

@vestal hound :white_check_mark: Your eval job has completed with return code 0.

001 | True
002 | False

[vestal hound]

whereas in most other languages you'd need to do something like (1 < 3) && (3 < 6)

[unreal bolt]

oh

well, now i have it like this:

if ((item0Inner, item1Inner, item2Inner) == (p, p, p)) return [true, p, item0.id, item1.id, item2.id];
if ((item3Inner, item4Inner, item5Inner) == (p, p, p)) return [true, p, item3.id, item4.id, item5.id];
if ((item6Inner, item7Inner, item8Inner) == (p, p, p)) return [true, p, item6.id, item7.id, item8.id];

if ((item0Inner, item3Inner, item6Inner) == (p, p, p)) return [true, p, item0.id, item3.id, item6.id];
if ((item1Inner, item4Inner, item7Inner) == (p, p, p)) return [true, p, item1.id, item4.id, item7.id];
if ((item2Inner, item5Inner, item8Inner) == (p, p, p)) return [true, p, item2.id, item5.id, item8.id];

if ((item0Inner, item4Inner, item8Inner) == (p, p, p)) return [true, p, item0.id, item4.id, item8.id];
if ((item2Inner, item4Inner, item6Inner) == (p, p, p)) return [true, p, item2.id, item4.id, item6.id];
```something else i could do?

[vestal hound]

🥴

okay back up a bit

[unreal bolt]

xd

[vestal hound]

what are you trying to do?

[unreal bolt]

tic tac toe ifs to check if game is done

[vestal hound]

ah.

in general

you can do like a == b == c == d

and it will work

however, overall

this looks like your data model

is probably not well thought through

[native tide]

its javascript?

[unreal bolt]

ye

[native tide]

also i was thinking. nan == nan so sorry

[vestal hound]

it is?

[native tide]

also ignore me then.

its js i thought was python

[vestal hound]

oh then this won't work

[native tide]

===

[vestal hound]

oh yeah that's not Python

I realised

[native tide]

3 equals in js

[vestal hound]

no colon after the if

[unreal bolt]

if u wanna see my mess: https://github.com/ericmp33/tic-tac-toe

[vestal hound]

hold up then what are the parentheses supposed to do

[native tide]

haha im out. its .js 😆

[unreal bolt]

wdym?

[vestal hound]

(item0Inner, item4Inner, item8Inner) == (p, p, p)

[native tide]

use a swtich

[vestal hound]

why do you have parentheses here

[native tide]

delete all that. it was python

[vestal hound]

JS doesn't have tuples

also, yes

in general

you should ask JS questions here only insofar as they are relevant to webdev in Python

[unreal bolt]

oh true it doesnt work. just checked it :/

[unreal bolt]

idk where to ask javascript help :/ so i ask here

[native tide]

I'd love to make a website like https://ygg.fun, I've got my own website running now. What's my next step to constructing it, learning HTML?

[unreal bolt]

there is a js discord server or something?

[vestal hound]

it's off topic for this server

[vestal hound]

probably?

[unreal bolt]

wdym u got ur own website running now?

[unreal bolt]

okay, but dont u know some?

[native tide]

As in configured nginx and uWSGI, here it is: http://void.codes

[unreal bolt]

oh okay

[native tide]

Just says Hello There! atm but nothing special at all

[vestal hound]

nope

sorry

[vestal hound]

can you elaborate

you mean

[unreal bolt]

so yeah if u dont know html nor css u should go and learn right now (: @native tide

[vestal hound]

like how to build a website (in the sense of the code itself, as opposed to deployment)?

[unreal bolt]

np (; , ty anyways

[native tide]

In the sense of coding it - I've got no HTML/CSS/JS experience thus far, but I've got no idea where to even begin. I have no idea how to combine it all and make it work through Flask either.

[vestal hound]

well

you could also look into Django

[unreal bolt]

why?

he should go for basic things

html + css !

no?

[vestal hound]

well, you need a backend to serve that

of course, Flask works too

[unreal bolt]

yeah

but

[vestal hound]

but IMO Django is better because

[unreal bolt]

first things first

[vestal hound]

it comes with all the parts

that you need for a basic website

-> less dependency management

shrugs there are many paths

this is just one

[native tide]

Say I create a HTML document to structure the main page of my website, how would I get Flask to display that HTML doc?

[vestal hound]

I don't know the exact mechanism in Flask, but ultimately each Flask route handler returns a response

so you need to get the HTML into that response

if you want to fill it with data dynamically

you'll need a template

otherwise, a static HTML will do just fine

[fossil pond]

Tried it, not working idk why

Even used https://idiotwu.github.io/smooth-scrollbar/ but nada

[wicked sleet]

I learnt html how do i start learning webdev in python

i wanna be a backend one

[lime mist]

best way to maintain a server-state in a web server?

This system is made with Python Socket.io and is suppose to load-balance jobs across all available online workers

@sio.event
async def connect(sid, environ):
    server_state.workers_online += 1
    server_state.add_worker(sid)
    await server_state.rebalance_workers(sio)

    log(INFO, f"{sid} Connected!")

    await sio.emit("sid", sid, to=sid)


@sio.event
async def disconnect(sid):
    server_state.workers_online -= 1
    server_state.remove_worker(sid)
    await server_state.rebalance_workers(sio)

    log(INFO, f"{sid} Disconnected!")


@sio.event
async def envoke_workers_rebalance(sid):
    await server_state.rebalance_workers(sio)

The method to note here is server_state.rebalance_workers
and it updates this:

class ServerState:
    def __init__(self) -> None:
        self.workers_online: int = 0
        self.worker_job_maps: list[Worker] = []

here is that method in action:

async def rebalance_workers(self, sio) -> None:
        temp_worker_job_maps: list[Worker] = deepcopy(self.worker_job_maps)

        for worker in temp_worker_job_maps:
            worker.jobs = []
            worker.proxy = None

        proxies = Queue()
        for x in get_proxies():
            proxies.put(x)

        for worker in temp_worker_job_maps:
            if not proxies.empty():
                worker.proxy = proxies.get()

            else:
                break

        active_jobs = Queue()

        for x in get_jobs():
            speed = int(x[2])
            if speed > self.workers_online:
                speed = self.workers_online

            for _ in range(speed):
                active_jobs.put(x)

        while not active_jobs.empty():
            job = active_jobs.get()

            temp_worker_job_maps.sort(key=load_balance)

            for worker in temp_worker_job_maps:
                if job not in worker.jobs and worker.proxy is not None and len(worker.jobs) < MAX_JOB_PER_WORKER:
                    worker.jobs.append(job)
                    break

        self.worker_job_maps = temp_worker_job_maps

While testing I noticed a glitch in worker_job_maps list. I'm speculating it was because this is not the best way to update these variables as some other connect/disconnect/forced_rebalance can evoke this while it might still be getting processed.

What are your thoughts? Is this the right way? If no then how can I make this better?

I started with Flask in June of this year. Even though I sensed my web project was complex enough, Flask gave me a start to grasp web development (backend, application, front end). After about a month I flipped to Django July 9, 2021. Just under 2 months later and I'm 28k lines of code in. 🙂 The website I'm building can be found through my profile.

[ionic raft]

I've got a vague idea on that, mainly because I stumbled across it. You use DNS records. For the domain I'm working on I simply set up DNS to setup one server for mail and another for web. Are you familiar with DNS? If not, I suspect you'll need to brush up. I'm no pro, but I do have a domain and dedicated mail service set up for lanesflow.io

[wicked sleet]

Ohh nic3

So you means I should start with flask?

[ionic raft]

For Flask, depending on how you learn:

• Books are deep, but slower
• Boot camps should give projects, but not as deep as books (udemy.com)
• As for tutorials, they're good so long as you continue to delve deeper. I recommend corey schafer on You Tube.

[formal forum]

I thought I should delete the A and AAAA records?

[ionic raft]

Yes. Definitely start with Flask.
That first month was invaluable. And if your site isn't that complex, Flask can definitely be enough

[wicked sleet]

Ohok

I'll start with it

[ionic raft]

There you go. That sounds right. But in truth, I'd still need to look the deets up for DNS

[ionic raft]

I LOVE web dev...Seriously. Tons of fun. You get to code in Python and can see the results instantly in the browser. Amazing experience

[formal forum]

[ionic raft]

I just built a billing/hour tracker for users in my web app...in less than 24 hours...
I started with tutorials. about 11 apps in the web application later, and I'm starting to get comfortable with Django

🙂 This has two modes...prepaid pool or hourly billing. Determined by the user when they update their profile

So yeah...Flask and Django...amazing frameworks. Worth the perseverence.

But what amazes me most about Django...is the SPEED of my site. I can only assume that my choice to limit JS on the front end has paid off big time. Ping aside, the click to render speed is astonishing...even when working with DB calls for user data...and on this site, there are DB calls for every page...some of them significant queries.

[lime mist]

any idea guys?

[inland oak]

there is always a room for improvement 😉
with a bit of caching we could speed up things further ;b

[ionic raft]

Indeed. Always room for improvement. 🙂
I suspect I'll miss the days when I could tinker with changes as the sole dev. Just rolled out a new app in lanesflow and have already refined on the image above.

[inland oak]

up to hundreds of times 😉

[ionic raft]

Well, hundreds of times on a split second...diminishing returns. 🙂
For the short-term I suspect I'm safe. The site is almost instantaneous right now

[ionic raft]

That said, when I get into react for the map app, that'll be a different game. I can see a JS front-end chogging up the render speed hard

[inland oak]

React is popular, but I am hesitant a bit about it

I don't like that it mix JS and HTML together

I would prefer to try Angular perhaps

its structure looks quite prefessional

[ionic raft]

I know right...I need the diagramming though. I'd have to see if Angular has the diagramming libraries...

[calm plume]

Agreed, that's why I personally love Svelte

It's pretty similar to Jinja2 and the Django template languages, in the sense that it doesn't add much new syntax, it's just a (very very) thin layer on top of regular HTML

[inland oak]

Angular attracts me for looking quite similar to Django structure, battery included approach
and having typescript as mandatory from the start

[ionic raft]

That's encouraging.
My goal is to maintain the rest of the site as-is and ONLY have the JS framework serving up the one app. I've no need for a UI across the site. I just want the diagramming for the one app

[calm plume]

From what I've heard, Angular is losing lots of popularity and satisfaction

[inland oak]

really? too bad.

[ionic raft]

Does svelte have diagramming libraries available. I need to build something akin to https://draw.io

[calm plume]

Yeah, take a look at this: https://2020.stateofjs.com/en-US/technologies/front-end-frameworks/. Angular is near the bottom

[ionic raft]

Great website

[inland oak]

huh. interesting

[calm plume]

Hmm, not that I know of.

[ionic raft]

That's the kicker...The only reason, for me, to go to a JS front-end is for one specific use case...to build a dedicated diagramming app that can interact with the data that the application layer can send to context in the template.

I'm ok with sacrificing speed for that app, but don't want it across the rest of the site

[calm plume]

Ah yeah, if it's diagrams you need, Svelte probably isn't what you want.

It's rather new compared to the other more popular frameworks, but it is growing fast.

[ionic raft]

Yeah. I bet 1-2 years from now that'll change. 🙂

[inland oak]

So hard to guess with JS frameworks

I think that's the most rapid technology

dissapearing and appearing new ones quite quickly 😉

[ionic raft]

I know right. Still, I'm glad to have the luxury of user communities highlighting risks/benefits

[inland oak]

well, since I dislike for some reason react

[ionic raft]

React is polling well on that website tho

[inland oak]

I would choose between Vue and Svelte then

[calm plume]

I personally hate it because of how messy it is, it's such a convoluted mix of JS and HTML

And state management can be hellish

[ionic raft]

Well, thanks for the insights chaps. Still got research to do. May have to explore a few of them. That website is very helpful tho

[inland oak]

https://www.youtube.com/watch?v=cuHDQhDhvPE
Oh yeah, that's one video

seeing helloworld in all frameworks quickly)

[ionic raft]

Definitely worth a watch. Ty for sharing

[inland oak]

yeah, that would make me afraid of it in advance

it does not sound like a way for a big clean project at all

[calm plume]

agreed

[inland oak]

actually it breaks one of clean code principles right from the start 😉

Robert Martin recommended to not mix different langs like that

liked the book. finally having an image where to go for cleaness

[inland oak]

after looking through video again

I think I am bought by svelte

[manic crane]

been getting this error for months =>
django.db.utils.IntegrityError: could not create unique index "Occupy_post_user_id_7dca33ac_uniq"
DETAIL: Key (user_id)=(1) is duplicated.
can someone help please thanks in advacne !

[rotund perch]

Seems like you are saving/posting data with an (id or whatever u required to make unique in the model) that exists already in the db.

I assume u are trying to create a user manually? So u got that error & it tells that the user id already exists

[manic crane]

yh bro but im confused i have no id field ?

[rotund perch]

Django automatically creates an id

[manic crane]

oh wow

[rotund perch]

I suggest to u something if ur input was correct, remigrate all models. That means u have to delete files(except init.py) in the migrations folder in every app and run migrations to start without existing users

Or just queryset to delete all users

[manic crane]

i read if delete all files expect init.py it can cause some later errors

[rotund perch]

Ive tried it couple times, but if ur project is sensitive then dont try it + if u want to try it and a bit afraid of errors just backup(do another copy of ur project)

But also try this before anything in console :
python manage.py shell

Import User
User.objects.all().delete()

[inland oak]

https://www.codeinwp.com/blog/angular-vs-vue-vs-react/

Angular looks still quite in demand though

in terms of job positions

equal to React

while leaving vue far behind

Perhaps it not in satisfaction because of just higher learning curve

[native tide]

hi

i need help

how do i make a div go to the top left center of my page?

[fossil loom]

Any ideas?

[rotund perch]

Videos or just readable content?

[inland oak]

[fossil loom]

Okay but i think i have to know how backend and web developpement work first

[calm plume]

In jobs, yeah

But in terms of the actual framework, I've seen satisfaction decreasing

[lime mist]

best way to maintain a server-state in a web server?

This system is made with Python Socket.io and is suppose to load-balance jobs across all available online workers

@sio.event
async def connect(sid, environ):
    server_state.workers_online += 1
    server_state.add_worker(sid)
    await server_state.rebalance_workers(sio)

    log(INFO, f"{sid} Connected!")

    await sio.emit("sid", sid, to=sid)


@sio.event
async def disconnect(sid):
    server_state.workers_online -= 1
    server_state.remove_worker(sid)
    await server_state.rebalance_workers(sio)

    log(INFO, f"{sid} Disconnected!")


@sio.event
async def envoke_workers_rebalance(sid):
    await server_state.rebalance_workers(sio)

The method to note here is server_state.rebalance_workers
and it updates this:

class ServerState:
    def __init__(self) -> None:
        self.workers_online: int = 0
        self.worker_job_maps: list[Worker] = []

here is that method in action:

async def rebalance_workers(self, sio) -> None:
        temp_worker_job_maps: list[Worker] = deepcopy(self.worker_job_maps)

        for worker in temp_worker_job_maps:
            worker.jobs = []
            worker.proxy = None

        proxies = Queue()
        for x in get_proxies():
            proxies.put(x)

        for worker in temp_worker_job_maps:
            if not proxies.empty():
                worker.proxy = proxies.get()

            else:
                break

        active_jobs = Queue()

        for x in get_jobs():
            speed = int(x[2])
            if speed > self.workers_online:
                speed = self.workers_online

            for _ in range(speed):
                active_jobs.put(x)

        while not active_jobs.empty():
            job = active_jobs.get()

            temp_worker_job_maps.sort(key=load_balance)

            for worker in temp_worker_job_maps:
                if job not in worker.jobs and worker.proxy is not None and len(worker.jobs) < MAX_JOB_PER_WORKER:
                    worker.jobs.append(job)
                    break

        self.worker_job_maps = temp_worker_job_maps

While testing I noticed a glitch in worker_job_maps list. I'm speculating it was because this is not the best way to update these variables as some other connect/disconnect/forced_rebalance can evoke this while it might still be getting processed.

What are your thoughts? Is this the right way? If no then how can I make this better?

[rotund perch]

Did anyone tried doing an API with django and showing response data with TEMPLATES at the same time. Ive tried that and I think its a good way if u dont want to use a frontend framework and want to implement an API. So does it include any later problems ive not notice? performance & speed? more querysets? less secure? etc..

NOTE: Doing this needs to have atleast 2 views, one for the API View, and the other is for the TEMPLATE View, same for URLs.

[wind dove]

I'm creating a Django app which is basically a social media app. On the social media app you can upload images, how should I go about storing these images on the server? Should I just write the image to a file, should I encode it to b64 and put in in the database or something else?

if someone replies please @ me

[rotund perch]

Development or Production?

[wind dove]

For production

[rotund perch]

do u know how to host files?

u need to host ur files with a host provider

[wind dove]

Not yet, I'm still learning a lot of this

[rotund perch]

okay, so I think u will need to learn hosting files first and then get into showing images in ur django app

[wind dove]

When I do that, how is the data stored? as a file for example image.jpg or is it stored in some other way

[rotund perch]

images are stored in the host cloud

[wind dove]

Alright

Thank you, I'll look into it!

[rotund perch]

[ionic raft]

@rotund perch I'm using queries in views.py with a Postgres DB in production. I've extended this to doing things like correcting user errors on input based on process requirements, updating templates dynamically, and presenting a rich data experience for the user.
The speed is astonishingly fast so far. But it is early days.

[ionic raft]

@wind dove I made the decision to stay away from uploaded media in production. Storing media on the app server loses statelessness of Django, and hinders load balancing potential. Storing to the DB presents security risks. I have opted to use external image hosting when needed down the line. For now, I upload images for articles (blog) as a static image behind the scenes and collectstatic inside the docker container.

[ionic raft]

@fossil loom I would expand on Darkwind's suggestion. Django documentation is excellent and I use it often for reference.
Have you started to look at a web dev framework, such as Flask or Django, yet?

[rotund perch]

so uve done it with 2 Views or an API View to TEMPLATE?

[ionic raft]

I code directly the queries into the view, typically using Class Based Views and logic within the form_valid function. I hope that answers your question. I'm only a couple of months into using Django

[rotund perch]

That seems intresting, how do users upload files into the container?

[rotund perch]

Okay TY!

[ionic raft]

They don't. I don't work with uploaded files for a number of reasons. I use forms to capture and control information input in a way I can completely control.
Uploading files in the field of process and business improvement is a misunderstood concept. It's based on the assumption that a file is the best way to capture data.

[rotund perch]

but what if u wanted to do an app that users can upload images on it, u'll need a host provider isnt?

[ionic raft]

In order to allow for load balancing later, or avoid security DB risks, I'd leverage a host with the resources and infrastructure to host the images and connect to them through URLs.

In other words, if a image hoster is trustworthy and has the resources to scale, why re-invent that wheel? Unless of course, you want to become an image hoster yourself

[rotund perch]

Yes Awesome ,Thanks.

Hey good people! I want to add a radio button to my Django form and I was thinking how do I introduce that variable to my model class?

Any help is appreciated

[manic crane]

what happens after i delete ?

[lime mist]

Can uvicorn serve 2 instances of a same web app to 2 connected clients?

I am using uvicorn to serve my socket.io server using heroku and there one of the things I'm maintain is an online users variable. I connected 2 clients which they did successful it still shows 1 as online users.

The code is perfect as if works fine when I test it on localhost. So my speculation is that uvicorn is somehow serving 2 instances of my server.

Can this be true? If yes then how can I disable it?

[bitter hamlet]

hello guys. I am pretty new to this area and I have to make a site to my school project in such a small period of time. Well, I was trying to use materialize css to do a Tab feature and I managed to do this, but I don't know how to align the iframes the way I'd like to. I'll show a pic of how (at least close) it should be

[gusty verge]

sorry buddy but i don't know

[ionic raft]

@fossil pond I would use a CharField with choices=CONSTANT in the model, the radio button input type on the template (https://www.w3schools.com/tags/att_input_type_radio.asp) and use css to style.

Or at least, I'd start that way 🙂 I've not done radio buttons. But I do choice inputs all the time.

@fossil pond I've made use of the select input to great effect on a filter for lists on my Django site...

[rotund perch]

All data on the data base table will be deleted

Anyway for counting requests or responses or queries per action in django?

[cerulean badge]

can you filter with model method with django_filter library?
or do i need to write my own logic in a function?

[ionic raft]

I wouldn't be surprised to see a library or function for this. But for purely solving this with just queries:
Setup an integer field in a table, every time a view is run query for the counter, add 1, save back to the table.

(context django) if i have textfield with blank=True do i need to provide default?
or does it have empty string if no value is provided?

[eternal blade]

blank is if the value can be empty in Forms

you will have to supply a value for it if the field is not nullable

[slim vigil]

got a quick question

@ me if anybody can help or give some advice

basically

im working on a game rn

a text based RPG

that's just text only

and i wanna put this on a website

as opposed to like a downloadable exe that runs in the terminal (the way i currently have it)

and what's the easiest way to go about this

im a total beginner with python webdev

actually nevermind

ignore that

Hi, im trying to make a simple endpoint @upbeat sigil_view(['GET']) that returns a string, does this look correct?

def simpleEndpoint(request):
    return Response("Hello world")```

or should i just return "Hello world"?

so just removing Response

And how can I test if this works?

[rotund perch]

Its correct, if u want to test it u can either use postman or a browser

Just do a url that points to that function to call it, and write the url in the browser

[native tide]

Sweet

Thank you 🙂

[fossil pond]

Hey guys! For my Django routing it goes to R:\Projects\Websites\project\main\static\images\ when it should not go to static idk why that's happening. Has anyone faced this issue?

[cedar flax]

hey guys ! i have a question. now when developing apps with kivy, or desktop apps with tkinter (or something else), orr even websites with django+flask. am i able to design first in figma or adobexd and then convert those files to the code ? or how does it work ? because for example .. most of kivy apps look ugly, soo designing them with figma in my opinion is better and then transferring them to the code. is that possible ?

[mystic wyvern]

what is the problem the static doesn't work ?

[fossil pond]

Static works. When I redirect to the webpaage it is going to static instead of templates.

I fixed it by changing the redirect link from href ="/contact" to href="{% url 'contact' %}"

But strange because for my other pages href ="/resource_name" is working fine

Would love to know why it happened

[mystic wyvern]

/resource_name i am actually doesn't now what this do but in django when you want to redirect to any given page you should use this {%url %} i think this called jinja or something like that

[fossil pond]

Yep thanks! I'm still wondering why is it working for my other files

[mystic wyvern]

@fossil pond
can you plz show me your urls file

[native tide]

someone know why the fontawesome stuff is only working once?

i used the links on differtent html file but it only works on one

[mystic wyvern]

you may just forget to add another backslash / like this href ="/contact/"

[native tide]

ah i forgot to do this on every site:
<script src="h ttps://ki t.fontawesome .com/5136008 754.js" crossorigin="anonymous"></script>

[fossil pond]

Ah no that's not the case

[mystic wyvern]

.

[native tide]

how can i change the size of a container with flexbox?

[fossil pond]

No issue with that either

    path("", views.home, name="home"),
    path("projects/", views.projects, name="projects"),
    path("project/<str:pk>/", views.project, name="project"),
    path("portfolio/", views.portfolio, name="portfolio"),
    path("inbox/", views.inbox, name="inbox"),
    path("contact/", views.contact, name="contact"),
    path("message/<str:pk>/", views.message, name="message"),
]```

[mystic wyvern]

Did you try adding a backslash like I told you?

dude can you show me what the error when you want to redirect

is it page not found ?

[ionic raft]

What is the line of <script> you're using to reference Font Awesome in <header>?

[ionic raft]

Including static at the template start combined with {% static url 'url-name-here' %} is the guaranteed way for it working. If not calling static worked for another page , I'd be curious to see url.py for the app, along with the template html. However, understanding why it worked using the incorrect approach is probably not as helpful as understanding the correct way to call on urls within Django. I hope that makes sense. 🙂

[native tide]

its fixed i missed the import link on my other html files

[ionic raft]

Good to read 🙂

[fossil pond]

When I add the extra backslash it redirects it twice. I get a portfolio/portfolio call

[ionic raft]

Corey Schafer, YouTube. I started with him July 9. 28k lines of code later and the result is in my profile. Great tutorials

[fossil pond]

urls.py:

from django.urls import path
from . import views

urlpatterns = [
path("", views.home, name="home"),
path("projects/", views.projects, name="projects"),
path("project/str:pk/", views.project, name="project"),
path("portfolio/", views.portfolio, name="portfolio"),
path("inbox/", views.inbox, name="inbox"),
path("contact/", views.contact, name="contact"),
path("message/str:pk/", views.message, name="message"),
]

and for the template even if it is blank I get the same output so I doubt it is relevant. But thank you, I shall use the correct way. A few bad tutorials can really ruin a lot of hours!

[ionic raft]

Not being familiar with figma I can't say anything in that regard. However, as someone who started learning Django recently, I'd suggest that developing code within the Django application layer (views.py for the app) or Flask is something that is best from within Django. There are a number of reasons for this, but explaining them if you don't know Flask or Django could quickly get confusing.

The idea of trying to port Python into a Django app doesn't strike me as an intuitive approach. Django/Flask is a framework that offers a way of building a web application with a spectrum of potential. But then, the use case of what your code is trying to accomplish would have a bearing on this. Most Django python code I've worked with is mostly about CRUD with the DB, and building the interface with the front-end (the browser). What I like about web applications is that once I'm clear on html/css (and even JS if I feel I need more dynamic behaviour) I've got the question of UI addressed.

[ionic raft]

Yes...a bad tutorial can be BRUTAL. I feel your pain. That said, it is good to be on the other side. Ultimately, once you get including static, along with how the urls.py files work for each app, you'll find it all making more sense. I'm currently working on an web app that has 11 applications and likely more than 200 urls. Naming those urls intelligently so that it's super clear what you're working with gets more important as the web app scales. Also, using an IDE that will auto-populate can be a time saver like you wouldn't believe.

[ionic raft]

Are you using template inheritance?

[native tide]

not yet, im working my way up to django currently by learing css, squlite and js haha

[ionic raft]

When I use template inheritance, I'll throw such script lines into the header for base.html. That way, the script is always there and updated in one place.

[native tide]

still a long way

but do you know how i can reduce the size of a container with flexbox?

id like to shrink down the site a bit

i think its currently scaling with the desktop resolution size so no size limit

[ionic raft]

I have been using bootstrap, which comes with flex embedded. I typically manage flexbox by setting up as follows

            <div class="row">
                <div class="col-2">
                    <h5>Customer</h5>
                </div>
                <div class="col-2">
                    <h5>Type</h5>
                </div>
                <div class="col-2">
                    <h5>Scope</h5>
                </div>
                <div class="col-4">
                    <h5>Need</h5>
                </div>
                <div class="col-2">
                    <h5>Rank</h5>
                </div>
            </div>```
What the above shows is a row with 5 columns. Each row can be divided into 12 columns. I happen to have cols with 2-2-2-4-2 (which totals adds to 12).
Now, if image size is an issue, you might look at capping the width of the image by setting a width with css for the image and applying that class.

[ionic raft]

In turn, in subsequent rows I start again, and can declare a col structure that is the same or different. It feels intuitive now that I've been using it for a couple of months, and comes down to thinking...each row can have upto 12 columns....

[native tide]

i fear that when i switch to bootstrap one day that my whole grid system is doomed xD

[ionic raft]

that's a fair assumption. I'm not pitching Bootstrap or Tailwinds. However, what they did give me was an effortless and intuitive entry point to flexbox. It's astonishingly simple to manage flex with a css framework.
On the inverse, one day I should try flex with vanilla css 😄

[native tide]

😄

[ionic raft]

but then, I didn't start coding with Python to become a css master 😄

I needed enough css to get a UI that works for me and looks decent.

[native tide]

tkinter works also for UI but yea css is simple and has more fancy features 😄

but im still a beginner with html, css etc so bootstrap is kinda like a game mod, modding/adjusting the code/features itself?

[ionic raft]

Thankfully, I'm clear on becoming a web developer. So I'll never really need tkinter. It was good to learn from, but it looks old school.
Even with a framework I'm getting clearer on css. There is tons of potential with layout, and there is some css stuff out there that is mindblowing.

[ionic raft]

Bootstrap/Tailwind is an easy vector into styling. They're taken care of a lot of the things you're most likely to need. They're also proven and tested, so for the majority of UI demands they're a rapid way of getting a build. I wanted my web app project to expand in functionality and have a consistent UI. Bootstrap gave me a quick way to establish a UI I liked. And I still like 11 applications later in Django.
That said, there's also the JS Framework route...which takes UI and behaviour to whole other level.
All said and done, I'm happy with my start with Bootstrap. For the next project I'll try Tailwinds for the experience.

And then one day, when I've got the time I'll delve deeper into css. However, a css Framework introduces you without requiring you to understand it all.

[native tide]

so it makes things simpler compared to vanilla css?

[ionic raft]

Simpler. Hands down. There's a learning curve. However, there's also great documentation.
I started by querying how to "do something with bootstrap/tailwinds stack overflow" and someone had the answer already out there.
Bootstrap allowed me to move quickly into focusing on function, with the comfort that form/style is great. My css file is 650 lines, and it's been weeks since I touched it.

I hear great things about Tailwinds though. So either flavour comes well used and regarded

[native tide]

alright i will take a look into it but i really fear it just ruins my whole project xD

[fossil pond]

Has anyone here used crispy forms? I want to make a really cool looking contact form with it. It has bootstrap integration. Can you share some good resource if you have?

[ionic raft]

I'd caution changing from vanilla css at this point, unless you want to rebuild...

[ionic raft]

I use crispy ALL the time with Bootstrap. Amazing

[fossil pond]

Aah I’m about to go to bed now. I’ll ask you my questions tomorrow.

Sorry xD

If you have any resources please share them now I’ll look at them when I wake up

[ionic raft]

Be happy to help. I'm around every day.
As for resources, I was introduced during a 100 day bootcamp on Python. It's actually quite simple. I can show you the key bits to do for your Django project. There is a pip install, settings.py to configure, and then the include for the template. Quite simple tho

[desert cradle]

How do you implement this in html?
list_var[index].option

[ionic raft]

What framework are you using? Flask, Django, other?

[desert cradle]

Use Django

[ionic raft]

So, you're using jinja2 for templating.
Are you using class based or functional view in views.py?

[desert cradle]

umm..I dont know..I used function.

[ionic raft]

OK. Sounds like functional views.
So, you need to build the context dictionary to pass over to the template.
How you populate that dictionary is going to depend on if you're working with a DB.

the context dictionary is going to look something like:py context = { 'year': get_current_year() }

Once the context dictionary is built, then you can call on that in the html template:

{{ year }}```

[desert cradle]

I received data from DB and handed over the list information to context. But I want to refer to a specific index value within html, but I can't.

[ionic raft]

If you pass over a list, then in the template you can use a for loop in the template: ```html
{% for element in list %}

Html

{{ element }}
{% endfor %}```
The for loop in jinja feels just like a for loop in python. This can extend to dictionaries as well.

[desert cradle]

Thank you. I got it.

[ionic raft]

Looping inside html allows you to amazing stuff. Good luck 🙂

{% load index %} in jinja can be done too. You can import index into a template, and then use the {{ element|index:forloop.counter0 }} tag to manage multiple lists within a for loop.
If you use index though, you need to import a package for that.

[desert cradle]

There's one more question. If i receive the variable 'location' in the first for loop, how do i refer to the 'location' of the list?
ex)in Python
for location in var: list[location].option

'location' is list.

[ionic raft]

This where you can make use of the index...
If you know the index, then you can run an if statement inside the loop:

{% for element in list %}
  {% if element == target_value %}
    # do something
  {% endif %}
{% endfor %}```

[desert cradle]

I think I got the hang of it. Thank you.

[ionic raft]

It's not hard. Everything you're looking to do is do-able 🙂
Calling specific index values and conditionally acting on them requires a bit more thinking tho

[ionic raft]

One thing though...if you want to run on the counter you can get specific about using the forloop counter to match for the indexhtml {% elif failure_is_late|index:forloop.counter0 %}

[inland oak]

Sorry to ping you. Just one more question about Svelte.
is it not having problems with State management?
Should be better in this regard Vue.js or Svelte can work with it finely too?

Svelte looked just so attractive to me, quite interesting to choose, but needing to know if there will be not problems with essential libraries

Or better to go safer vue.js

https://svelte.dev/tutorial/writable-stores
hmm, official svelte docs are broken for stores functionality
the buttons aren't working

I think vue.js would be safer for startup purposes

svelte looks like lightweight solution for pet projects at the moment

hmm, nice typescript is supported in svelte
https://svelte.dev/blog/svelte-and-typescript

[opaque rivet]

Why not React? Nice and simple and it's the new craze.

[inland oak]

because its mix of js/html/react abstractions look messy being all together ;b

check how Svelte looks clean

[wide canyon]

Hello

https://bdvade.hashnode.dev/building-chat-apis-with-django-rest-framework-and-django-channels

[opaque rivet]

Looks cool. I'd probably learn Svelte over React but I'm way too far into it now and the job prospects are the best. Looks good tho.

Might not be as many community libraries to use though.

[wide canyon]

I wrote an article for real time chat. I used the header to pass the token for token authentication. Im working with a frontend developer now and i was told it's impossible to pass custom headers for wbsockets through js. I have to change the middle ware to make it take token through query parameters. Ive done that. But I'd like to know if there's a way to pass custom headers for ws requests

[inland oak]

yeah, from job perspectives better probably to go for the second best option: Vue

for my pet projects, I would definitely go Svelte though

For me, state management with stores is working perfectly

[calm plume]

Did you click "show me" at the bottom of the tutorial?

If you do that, then it should fix itself

[inland oak]

ops. it is working now 😉

typescript is supported by svelte too

what else to wish?

I'll take svelte for myself ;b

[dusk portal]

i wanna give user a add to cart /bag option how can i do that

@ionic raft

[opaque rivet]

@inland oak pretty sure TS is supported by all the major frameworks.

[inland oak]

svelte is young one

it started to support TS only in 2020 year

well, svelte appeared only in 2019 year

[inland oak]

https://2020.stateofjs.com/en-US/technologies/front-end-frameworks/
youngliness is not a problem for a huge interest to it though

[quick cargo]

Svelte is very nic3

[inland oak]

love from first without even trying it ;b

[quick cargo]

The lack of a virtual dom runtime also makes it probably the go to if you want browser support

Its the only frameworm I've used that supports my ipad with safari that hasnt bren updated in 6 years

I've been making https://dev.lnx.rs with it

Previous mostly worked with vue or react

[inland oak]

what would you choose between them?

if you would be limited only to them

[quick cargo]

Svelte 100%

[inland oak]

except svelte? 😉

[quick cargo]

After working with it for a while its definitely my favourite framework

After that probably vue

Generally i prefer the template layout svelte and vue

[inland oak]

thanks. interesting.

a bit curious how would some dev compare his experience with angular too

eh, if only I had a bit more time to learn frontend 🤔 it would be nice to play with svelte

but I am bit too busy learning devops stuff

[native tide]

window.redraw = function( _id, endpoint ){
$.get( endpoint, function( data ) {

a method that just redraws returned html to the dom is also cool.

and just use python

[manic crane]

wow wont that be bad

[desert estuary]

idk whats going on isn't this how u start a virtualenv

[tiny snow]

#editors-ides

[desert estuary]

i guess this is more of a python prob cuz im working on flask and i had this project on windows now since i shifted to linux idk howo to do so
should i still go to #editors-ides

[tiny snow]

Well it's definitely not a web dev problem

[dusty urchin]

Does anyone know how I can split files and make them use the same imports without writing it on top of each file separately?
Basically I want to do all my imports once (like general imports) for a bunch of files to avoid redundancy of the code.

[rotund perch]

if its sensitive data of course its bad, but in ur case u will need to delete all users from the users table so u can recreate new users.

[manic crane]

okay so my best chance is to delete all files expect init.py

[rotund perch]

or do this

[thin lance]

this is for web dev try in #python-discussion

[manic crane]

ok great thanks

[rotund perch]

np

[thin lance]

you can import everything into one file and call that file in your main ... but I think it's stupid because you complicate your code

[dusty urchin]

That's not what I want.

I have multiple Flask Resources and I don't want in each resource:

from flask_restful import Resource
```If that makes any sense.

[thin lance]

I get it now

I don't think that's possible

[dusty urchin]

Me neither after thinking about it for longer

So I want to have 2 webservers running on the same machine. If I purchase an additional IP for that machine, then simply set the host to the desired IP for that server, would that be all I need to do, or would more configuration be required?
Please ping me when responding

[inland oak]

you could make it work without purachasing additional ips

with a bit of nginx rules you could setup...

if requests start with /somepath, then they go to first web server

[topaz finch]

I am running Apache on this server btw

[inland oak]

if with / path, then to second server

[topaz finch]

Am I able to do it by subdomain?

[inland oak]

well yeah, it could be used too

But!

better just deploying to two servers ;b

what do you deploy?

[topaz finch]

Right now I have 3 servers for 3 different webapps, but I figure if I can just stop purchasing more servers that would be good. I am going to add a webserver to a Discord bot in the same application, aiohttp

[brave stag]

how to test Django signal 'user_logged_in'?

[fossil pond]

Hi guys! I'm having a problem with a multiple type checkbox that I've implemented using crispy forms on Django. I get an error saying that they are not the right fields when a user chooses them.

project_type = models.CharField(max_length=20, null=True, choices=TYPE) : models.py
project_type = forms.ChoiceField(choices=TYPE, widget=forms.CheckboxSelectMultiple) : forms.py

What mistake did I make?

TYPE = [ ('mobile', 'Mobile'), ('desktop', 'Desktop'), ('web', 'Web'), ('other', 'other'), ]

It appears in the UI but when someone chooses 1 or more values , a JS prompt is received saying that the fields aren't right

[topaz finch]

@inland oak Do you think I ought to just get another server, or should I be fine just setting it up via apache configs?

[inland oak]

depends on what you are deploying

describe a bit

[brave stag]

I'm implementing the user login activity
so when the user logs in It fires a signal which creates an entry in a table
but while testing the login with the client it also fires the signal and the signal is expecting a request

Need help in this guys

[topaz finch]

I have a Discord bot, and I want to set up a subdomain for it, so that it has its own small website. I am deploying the Discord bot and webserver in the same application.

[inland oak]

better to have two different servers ;b

you could be forced to have one server though

depending on how you will choose exporting data

bot could be having some backend tied to it anyway

but web server could be on a separate server anyway

[topaz finch]

Im running the bot and aiohttp server in the same application, so I wont really need to export data

Ill look into getting another server, thanks for the advice

I will probably just do development on my main server on a port for now

ok

how to get above return button

thats what i want

@timber cloak ?

[timber cloak]

instantiate the widget before the return button

Im currently using SendGrid, but 100 free emails a day is about to be too few. Am I able to retain my domain as the domain for the email?

[frosty cedar]

@topaz finch is it a domain you bought? like your own .com/whatever top-level domain?

[topaz finch]

Yes

namecheap ftw

[frosty cedar]

@topaz finch you should be able to move your MX/SPF records to whatever email provider you choose then

[topaz finch]

Most dont seem to have good enough free plans, and I am not looking at paying more than a few bucks. Thats why I am trying to figure out how to set this up with my own VPS servers

[frosty cedar]

@topaz finch there is a lot to consider with hosting your own email. standing it up, securing it from attacks, privacy/data retention. not to dissuade you, but I would vet pricing from other providers before taking it on yourself.

[topaz finch]

Fair enough, any suggestions as to who? I mean, I would be fine with sendgrid if they didnt go from free to $15

[frosty cedar]

while I hate to pitch Amazon, they'll give you 62k emails per month under their free tier for SES

@topaz finch mailgun has a flexible, "pay-as-you-go" offering

[dense slate]

In Django+React (with jwt tokens), I found a weird effect that when I login through my site (react), it gives me a JWT token as expected but also creates a session cookie. When I go to log out through the client and then log back in as another user, it logs me back in as the same user as before.

I get the feeling that the session is what's still active and being authenticated but I'm not quite sure what part of the auth process the hiccup is in. Anyone seen this before?

@tawny pollen To be able to interact with a database, you have to do so with SQL. The django ORM maps your pythonic code into SQL. e.g. writing a model then migrating will create a table in the database.

@runic lodge Django/ Flask acting as APIs. More importantly is the frontend framework. I've had simple drag and drops with React. It gets pretty complex. Look at react-beautiful-dnd.

It means:
you are writing python code with classes.
Instead of writing sql

Interesting so dev programming pipeline is python > flask(api)/Django > React(or VUE) for front end ?

How does the api for flask work?
I know python would be for backend, breaking down code, running algos etc. and whatnot but what about that mid level stuff

API mods:
flask: https://flask-restful.readthedocs.io/en/latest/
django: https://www.django-rest-framework.org/

@runic lodge wouldn't call it a pipeline. But yes.

Svelte can work for frontend too

Help django class based view
template:

<form action="{% url 'search' name=contact_list.first %}" method="GET">
  {% csrf_token %}
  <input type="search",name="search", placeholder="Search contact", aria-label="Search">
  <button type="submit", class="btn btn-success">Search</button>
</form>

view

class SearchContact(ListView):
    model = AdressEntery
    template_name = "main/search.html"
    context_object_name = "src"
    def get_queryset(self, *args, **kwargs):
        queryset = super(SearchContact, self).get_queryset()
        search = self.request.GET.get('search')
        queryset.filter(name__startwith=self.kwargs['name']) #it should be here queryset.filter(name__startwith=search)
        return queryset

the problem is that my self.request.GET.get ('search') returns None

I've got an api/views.py that goes like this:

from functions import connect_mongodb
mongo_client, db = connect_mongodb()

And a functions.py like this:

def connect_mongodb():
    mongo_client = pymongo.MongoClient(f"mongodb+srv://{MONGODB_PATH}")
    db = mongo_client["django"]
    if DEBUG:
        print(f"Connected to MongoDB ({__name__})")
    return mongo_client, db

When api/views.py starts it prints Connected to MongoDB (functions) since connect_mongodb() is imported from functions.py. How can I change it so it prints Connected to MongoDB (api.views) like if I were to print __name__ in api/views.py (that returns api.views) but still keep the function imported?
