I doubt you can re-create that speed with flask

[quick cargo]

i Mean you sorta can

Flask's eco system is vast enough to provide it

[blazing jetty]

@left kraken did some debugging

I can't execute it in the directory, but if I move the file somewhere else it works

no idea what could cause it

[left kraken]

You can use blueprints to speed up devel of a app, also equip yourself with extra schema validator

[blazing jetty]

XSD

I had socketserver.py in the same directory

and it interfered for some reason

[left kraken]

Glad to hear that you fixed this issue

[limber laurel]

If I do this, the code works, if I make it so the interpreter doesnt shit itself it doesnt

oh, I had to mark the directory as source

cuz in django it creates a project in the project

and uses the second project file as the source file

hey guys, so I made a chatbot using tensorflow and tflearn in python.. it works but as a stand alone app. i wanted to make a django website and add the chatbot in it... could someone please list resources i can look at (it’s my first time doing this and I don’t know what to even search for)

p.s. I know django.. I just wanna know how to integrate the chatbot into the website

[quick cargo]

I mean you really dont need much JS todo stuff

JS is useful to know if you wanna do certain interactions

but overall no its not massively needed

[limber laurel]

Could someone help me with me not being able to find my html template?

Probably more of a JS question, but here goes: does anyone know the best way to handle the soft keyboard on Android? The resize event triggered by focusing on input elements is messing up my contact form layout. The method of seeing if only the height changes I've seen on some blogs does not seem like a tenable solution. Any help is appreciated. Thanks in advance.

[topaz widget]

If you want to do front-end stuff, you should know JS.

You can build a website without any JavaScript, but almost all modern web UIs use some JavaScript.

[brisk spear]

Ok

[rustic pebble]

Does anyone know how I can set environmental variables in nginx, the default export NAME=VALUE in Linux does not seem to be working and I am having an issue with flask as it is not reading them

[topaz widget]

For anyone curious, I figured out how to deal with the soft keyboard deployment on Android, which seems to work fine. Here is the code (JavaScript):

// Function to determine whether soft keyboard has been deployed
function isSoftKeyboardResize() {
    // Only applicable to touchscreen devices
    if ( 'ontouchstart' in document.documentElement ) {
        if ( window.innerHeight < preResizeWindowHeight && window.innerWidth == preResizeWindowWidth ) {
            isSoftKeyboard = true;
            return true;
        }
        else if ( window.innerHeight > preResizeWindowHeight && window.innerWidth == preResizeWindowWidth ) {
            isSoftKeyboard = false;
            return true;
        }
    }
    // Return false if not a touchscreen device or orientation change
    return false;
}
// Change formatting if soft keyboard resize
function softKeyboardReformat() {
    if ( isSoftKeyboard ) {
        body.style.height = preResizeWindowHeight + 'px';
    }
    else {
        body.style.height = null;
    }
}
// Functions to run on resize of window
window.addEventListener('resize', () => {
    if ( !isSoftKeyboardResize() ) {
        // Resize functions to run under normal resize circumstances
    }
    else {
        softKeyboardReformat();
    }
    preResizeWindowHeight = window.innerHeight;
    preResizeWindowWidth = window.innerWidth;
});

What is the python3 equivalent of PHP's json_decode ?

[native tide]

json.loads?

[topaz widget]

What @native tide said. Not sure what json_decode does, as I don't know PHP, but that seems right. json.loads turns JSON into a Python dictionary. If you have json as a file, use json.load. Remember, you need to import json.

[drifting anvil]

@topaz widget @native tide Thank you both.

[topaz widget]

Web pages are files.

But a functioning web page usually utilizes multiple files to run.

[shy willow]

how can I iterate through all django objects and change a value for them?

[opaque vigil]

I need help with React.

I have this component called ListGyms that renders two child components (one each time depending on the state). This component routes to the main react page, and stays rendered regardless if the child components (either of them), gets rendered.

These 2 components are rendered from a click on a button that is a part of a ListGyms component. Now, what I need to do is pass id as prop to these 2 components, because I need it to render some data from the backend. I am not exactly sure how to accomplish my task.

I am using react-router-dom for routing.

Here is github gist that shows you the code for all my components.

https://gist.github.com/eonbre/10a6932a5fe471cb1d7c4398a1ef9b8b

Thank you in advance for any help or guidance.

Which is best database to be used as a beginner in python?

[stray quiver]

sqlite

a small question from noob. why i need this dot before models when registering model in django?

[wheat sorrel]

Hi guys I'm hoping to start a new project soon which i will admit now is quite ambitious, i am planning to try and use chat logs combined with a machine learning algorithm to create a chatbot which will be able to sustain as good a conversation as I can get it to do. I want to use real chat so it learns true responses to questions. But i'm not sure if i should make it so right now it can only answers questions on one topic, like a specialist on python and i wondered if anyone had any experience and could offer me some advise on what's best to do as well as if anyone was able to give me some clips of chats i could use for this project? Thanks in advance guys!! 😁

[real hare]

Hey guys, I'm unable to use my db on my Django project...

django.db.utils.OperationalError: (1045, "Access denied for user 'root'@'cpc76456-belc9-2-0-cust5.2-1.cable.virginm.net' (using password: YES)")

I'm seeing this here when trying to launch the app, I can log into the DB, I'm connected to it using mysqlworkbench

[native tide]

You can go into the django source code and check out admin and see what it is, it's most likely a class and the dots would make sense.

[real hare]

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'GorillaFitness',
        'USER': 'root',
        'PASSWORD': 'mypass',
        'HOST': 'dbendpoint.blah',
        'PORT': '3306',
        'OPTIONS': {
            'init_command': "SET sql_mode='STRICT_TRANS_TABLES'"
        }

    }
}

I've specified the db properly on my settings file as well, omitted the sensitive information

[native tide]

The actual database doesn't really matter, if you are using python you are most likely communicating SQL within a pythonic way, via an ORM. If you are using Flask, use Flask-SQLAlchemy if you are using Django it has its own inbuilt ORM. These ORMs are used irrespective of the database (sqlite, postgres, etc.)

[visual oracle]

Hello. I use flask framework and I have one small issue. CSS does not update properties of input, but p works just fine.

Here is code as an example.

p{
color: red;
}

input#sbar{
border: 4px solid black;
}

[real hare]

change it to #sbar

[visual oracle]

I tried that. Did not work.

[real hare]

is it an id or class assigned to the html field?

[visual oracle]

ID.

It's like black magic to me. I tried without flask framework and it worked without any problem.

[real hare]

I dunno if you specify the colour in the border

[visual oracle]

I mean you can since it is working outside of flask.

[pallid idol]

guys, how can i get json info to send with request.post? for example i need to log in insiede a website, how can i get the json (payload) to send?

Any advice?

[real hare]

I meant in Flask, it seems it's expecting differing syntax

shouldn't be though, I tested that quickly, and it does indeed work in that manner

Try using the dev tools on your browser

[visual oracle]

Yeah it works in dev tools.

It's like completely ignoring what I have inside the css #sbar.

[west wren]

I'm using Flask-Migrate to check for differences in my code. However, Alembic doesn't seem to detect anything after running python3 manage.py db upgrade after the following change is made:

username = db.Column(db.String())

⬇️

username = db.Column(db.String(), unique=True)

How can I get it to recognize a table with an updated column like this?
Thanks in advance!

[native tide]

Can't remember, but I think you need to configure static files (e.g. css) within flask

[visual oracle]

Ok. I have found the problem. It's something to do with the browser cache. As soon as I deleted browser cache CSS started to work. I just hope that I don't have to do this every time I make changes.

[visual oracle]

Static files are configured well otherwise properties in p wouldn't work either.

[real hare]

ahh control shift r every so oftne caching can an annoyance

[west wren]

you can open the devtools and disable cache

tada and perfect

[visual oracle]

Epic. Will try that.

I think that works. Thanks.

Hi, I need help with Flask-WTF. Specifically with special character escaping.
I as understand flask_wtf escapes all special charachters by default, but when I type special characters i my field and try to access them in my view it gives me unescaped data.
For example field:

class Form(FlaskForm):
    title = StringField('Task', validators=[Required()])

then later when I enter value <script>malicious code</script> in html form and send it, I call

form = Form()
print(form.title.data)

and get the same unescaped value
<script>malicious code</script>
but what interesting is when I just print field itself it shows that value attribute is properly escaped

print(form.title)

gives me

<input id="title" name="title" required type="text" value="&lt;script&gt;some&lt;/script&gt;">

how can I get escaped data?

I am not sure how to call two Models in my views/forms, anyone?

you can set up a reverse relationship with the related_name attribute and then you can access your M2M field from both sides:

[mint folio]

You need to measure and weigh your costs/time/experience and then decide. Shopify gives you most of the stuff pre built. Doing it yourself would mean many hours of work to be put into it. And how many hours goes into it depends on your level of experience and the complexity of the project.

i don't know the word in english sorry but what i means it was : your html basile which fix the header is only inside the header and not into the body too

at some point i changed my header from div to header tag but i didnt change the closing tag

thats why it broke

[glass orchid]

ok so the good word will be tag, cool i know a new translation word 😉 and happy to help you

[swift sky]

how would you handle this situation

the user receives an email daily with updates about random work responsibilities

currently that data is being copy and pasted into a text area field in a form, and being stored in the db

and when rendered in the html its not keeping the format

it returns the data as just one large block of text

[past cipher]

is it HTML that is stored in the db ?

or just regular text

[swift sky]

im trying to make it so that the data is returned with font size and and whitespace

[swift sky]

it's just regular text i believe

[past cipher]

what do you mean by not keeping its format?

got an example?

font-size is done via css

maybe try variable|safe

if whitespace isn't being kept

try printing the variable in the back-end and see if it keeps the whitespace

[swift sky]

one sec

[swift sky]

but then how will it know how to differentiate titles or sections that need to be bolded

[swift sky]

it's currently set as variable|safe

[past cipher]

insert it as HTML into the database if you want to have headers etc

[swift sky]

and will the db actually store the html by default?

[past cipher]

no

you have to send the html to the db

if its a basic textarea, its not gonna be html by default

[dusty belfry]

is flaskwebgui the best/easiest way for a simple UI to call my script ?

[past cipher]

maybe use a WYSIWYG editor

[swift sky]

but this editor

how would that work

[past cipher]

it replaces the text editor with its own text editor, and it retuns pure HTML that you can store in the db

thats one I used last month

checkout tinymce

[swift sky]

so the idea is the user uses this editor to write some stuff, and when they click update post it gets submitted to the db as html

[past cipher]

yeah i think its best you use an editor like one above

I pushed my repo to github when i created mine, lemme try find for you

[swift sky]

you made your own editor?

[past cipher]

no, I used tinymce

https://github.com/MrNaughtZero/neilWrites/blob/master/app/templates/admin/create-post.html

basically you want to include the tinymce cdn
init tinemce
when the user clicks submit, grab the content of tinymce and assign the value to a hidden input field
in the backend get the value of input field
insert into database

[swift sky]

im looking at your stuff now

and tinymce

uhhh

i dont use any of those webframeworks

how do you init tinemce

[past cipher]

look at the github.

its at the bottom

[swift sky]

yeah i saw thanks, just embedding it now into my app

@past cipher is this free?

[past cipher]

yah its the community edition

[swift sky]

having some issues embedding into my current html file

[past cipher]

what issue ?

just copy paste the code inside your script tag

and then change ID of your textarea

[swift sky]

i was embedding it incorrectly because there was html already present

expose api key though?

what is all this in your github

          selector: 'textarea',
          block_formats: 'Paragraph=p; Header 1=h1; Header 2=h2; Header 3=h3',

            {text: 'JavaScript', value: 'javascript'},
            {text: 'CSS', value: 'css'},
            {text: 'PHP', value: 'php'},
            {text: 'Ruby', value: 'ruby'},
            {text: 'Python', value: 'python'},

[shell hollow]

hi guys, sorry i'm trying to search from older message about this issue but i cant understand the answer.
i'm trying to run django-admin runserver and got this error msg:
django.core.exceptions.ImproperlyConfigured: Requested setting DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I already had this in manage.py:
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mySite.settings')

am I doin it right?
however if running using python manage.py runserver its working.
i'm just curious why django-admin not working.

[toxic flame]

Is it possible for django to set for example:

127.0.0.1:8000/example

To normal html without using any of the django properties?

[rotund token]

wdym?

[twilit needle]

yes, but the django html thing is limited
I would recommend having django as the backend and then using
react at the front.
django is really powerful and will also help scale your application

[toxic flame]

Seo wise everything is client side rendered

[twilit needle]

no I didnt mean that django cannot render

you dont have the tools to do AJAX and stuff

thats the catch
browsers cannot run python

[toxic flame]

For SEO django is not the best choice imo

Because it loads and creates the HTML when is requested

so my solution is put everything Django on a subdirectory

[twilit needle]

? I didnt get you

[brisk spear]

Hey all

I have a doubt whether should we install flask again while creating a new project again ?

Also suppose I am using python3 so what happen if I install virtualenv? Will it work properly?

[brisk spear]

I mean that I wanted how to make a chat bot?

[zenith flume]

heey so i made a website with python and html there are pictures of my cats http://zeroiq2018.pythonanywhere.com

[brisk spear]

Bro are u beginner

[zenith flume]

in what

[brisk spear]

In html and python

[zenith flume]

well i have been coding python for 5 months now but in html and flask only a month now

[brisk spear]

Ok

Try to learn css and bootstrap

It will make your website attractive

Well then, good work

[zenith flume]

il try it

thanks

[brisk spear]

Bro listen

For every new project in flask do we need to install flask

Again?

[zenith flume]

im not sure

[brisk spear]

And how did you trigger the action event?

Is it with flask?

[zenith flume]

<form action="/cats/" class="inline">
<button style="background-color: saddlebrown" class="float-left submit-button" >go to my cats</button>
</form>

no html

[brisk spear]

Ok thnks

[zenith flume]

no problem :D,

[brisk spear]

Bro how much you know python?

Listen u used python 3 or python

[zenith flume]

python

[brisk spear]

Then you might have used virtualenv

Right?

[zenith flume]

i know the syntax learned pygames,tkinter,flask,pyautogui,ursina,panda3d

yeah i use it for everything

[brisk spear]

Bro one advice

Why don't u use python 3 it has built in environment

venv

It might be easier right?

[zenith flume]

il try it does it have a big diffrence

?

[brisk spear]

I guess venv is good

U don't have to install virtual environment if using venv

[zenith flume]

as said il try it out

[brisk spear]

Well ok

Had u tried 3.9.1

Has it got some difference

Or same

[zenith flume]

too which version?

exactly

[brisk spear]

Like other version

So I have made my own API using, Flask, FastAPI and I want to host it under api.domain.com, I have created an a record in the dns poitning to my unbuntu vps. But I'm quite unsure on what to do next

[marble gate]

You would need to add the api onto the server

which u can do with ftp

and u need to install python on the vps

then you would go to the api directory and run pip install on the requirments file

Then u can use a process manager and run the api

Hi all, does anyone know of a Python library that outputs Javascript? Similar to how yattag outputs HTML?
I realize this is kind of an odd use case.
I have a Python script that synchronizes some data on the backend of my server hourly with a third party API, and I'd like to add functionality to this script to output some of the data as a file with a Javascript object.

[gaunt marlin]

i don't think there are suck library, but javascript use format type of JSON you can come up with some logics to handle what you want to a JSON format to write a JS file

You would be looking at a static display type

the pink highlighted area is a static container

To make it so shit stays aligned properly i would also consider using a flex box to properly position the static stuff

otherwise it'll go a bit mental

flex + flex-column

for example it's pulling the headers and stuff [{'content_id': 2042, 'the_date': '02-01-2021', 'content': '

and the line breaks

 

\r\n```

this is my view

sql_query2 = "SELECT content_id, date_format(load_date, '%m-%d-%Y') as the_date, content from roll_call order by content_id desc limit 5"

and

data2 = cursor.fetchall()

fragment2 = data2

[native tide]

The one thing I see that may be an issue is the indentation of the for loops here.

how do you create or make a website

Show me your models

Your looping 3 things

Hi, I build the tool lifecockpit.com. Can somebody help test it?

[wanton ridge]

how can i check if the email adress and name already exists in the database. This codekeeps redirection me to the login

[brisk spear]

Bro u are using what database?

[thin dome]

have you writen it in django?

[native tide]

Are you sure you can have two different views for the same URL?

[past cipher]

I rebuilt a store I found online, with Flask if anyone fancies taking a look, see if I could change anything:

https://github.com/MrNaughtZero/uSell
Live Site: http://usell.store/

[wanton ridge]

@brisk spear mysql

[wanton ridge]

not sure, should it be a problem

[brisk spear]

Isn't it a sort of difficult to use

Bro where did u learn using database?

[wanton ridge]

lesson

and did tutorials

[native tide]

You tell me. When you make a request see if both views are working for that URL. Personally, I think your error here is because you have assigned two views to the same URL. I'd try to put print statement in both views, visit the URL, and see which one runs.

[native tide]

The database shouldn't matter too much, it's still SQL, it's not database specific

[brisk spear]

Ok

[wanton ridge]

ok ty bro will test it

[brisk spear]

@wanton ridge can u suggest some channel/website where it is well explained

[wanton ridge]

codeacademy@brisk spear

[brisk spear]

Ohk thnks

[wanton ridge]

no problem

[toxic flame]

itachi with a non itachi pfp

Epic

[toxic flame]

Maybe check all the entires with a loop, might be slow though.

Loop through the usernames in the database checking if there are matching

if match return a message and blah blah blah etc

That's the only method I can think of

[heady cipher]

how do you create a URL?

[wanton ridge]

i have a guess, the method get has to be in ('email') not ['email'] this is a post method.

[native tide]

did you check this?

[wanton ridge]

yes both are running

[native tide]

well in this case, when the user signs up they will always be redirected to login when the Password == Confirm...

You need to add another if/else statement checking if the email is available. If it is, sign them up, if not, show them an error message.

It would help to keep it within one function. Also, why don't you use Flask-SQLAlchemy? They should have a method for checking whether an entry exists or not.

[wanton ridge]

i am just learning flask, i am not expert not professional

and i know mariadb and mysql

so i wanna go with them first before i go sqlalchemy

[toxic flame]

You're parsing the entries from your database

And with the entries of the database you for loop it checking if the username exists already or not

for a in query:
  if str(email) == str(a.email):
    if str(username) == str(a.username):
      pass
  else:
     return (something)```

[native tide]

I recommend you learn flask-sqlalchemy, it will simplify a lot of things for you

[toxic flame]

django is alot easier kek

[native tide]

^^

[toxic flame]

alot of people says its monolithical

But like, you don't have to 100% use it's default settings, or it's built in admin / auth system, it's purely up to you.

[wanton ridge]

yeah i saw it too

[wanton ridge]

@toxic flame i mean i just began learning frontend and backend for 2month

[toxic flame]

I began 4 months ago

Well I learned django in like a week

python in 2 days

[wanton ridge]

i guess you programmed before so

[toxic flame]

I wish school taught me languages

django has a very nice documentation btw

[wanton ridge]

wanna dm me?

[toxic flame]

Sure

[olive tiger]

you should not use django-admin for this, use python manage.py runserver. django-admin is normally, used only twice: 1) to create a project and 2) to create an app in the project

[quick cargo]

well django admin will just run the same thing as manage.py in terms of running the dev server

[formal gull]

i need to tie in a web scraping application from an external source that can take in information given on a web page. how would this be accomplished? example: web page gets a user input number. application takes that number, inputs it to a search in another website, gets information on that site and returns it on the web page.

i have this application made using selenium and tkinter for a UI but work is not allowing this anymore so i want to just throw it in a web page some how.

how would i accomplish this?

[zinc hill]

How I did mine was using django, but mine is very simple idk if that would be any use.
it literally scrape covid data from the govt website and pass the info to HTML/CSS, I didnt use database cos I dont see the point.

How to learn advance things of Django

[lucid eagle]

go through docs

and there is also stack overflow

https://django-advanced-training.readthedocs.io/en/latest/

[still jay]

form.whatever.data = whatever or if your are using sqlalchemy then form = WhatEver(obj=whatever)

[edgy isle]

Not using wtf forms?

[still jay]

request.form["whatever"]

[still jay]

its mostly because its disabled

since u already know a inital value u can do something like ```python
name = 'value'
form_name = request.form.get('name', name)
print(form_name)

django?

I'm not sure how to differentiate between a guest and a user when the frontend (Vue) and backend (Python/Flask) are completely separate. I want to show a landing page with separate navbar to guests, and one with the tools to the authenticated users.

There's an API route that checks whether a user is authenticated using flask-login.

@bp.route("/isLoggedIn", methods=["GET"])
def check_if_logged_in():
    return jsonify(user=current_user.is_authenticated), 200

And I thought of simply checking this, and if it returns true set a Session Cookie that essentially goes: isUser: true and building the navbar based on that. But, users can simply modify this and it doesn't feel correct.

As I'm using Vue, requesting the route each time wouldn't be a good solution, as I'd have to rerender the navbar. Some searching on Stack Overflow and Google didn't help.

So... what's the best session, one-time approach to telling the difference between users and guests?

[past cipher]

is it possible to automatically set enviromentals when running app.py?

[native tide]

You can use Token authentication. I remember vaguely using it with Flask, but can't remember. iirc werkzeug-security has the authentication(s) you are interested in.

[native tide]

Have your model, add a filefield.

Then you can have your form, it will be a forms.ModelForm and specify the model & fields within the Meta class, your form will now have the same fields as specified in your model.

The CSS for my admin page in Django isn’t working and shows only the base html, any advice?

[near pendant]

have you deployed it somewhere ??

or you are running it on local machine ?
usually it's a case of loading static files (i think)

try 'python manage.py collectstatic' and then change your static directory (from settings) to that directory

[near pendant]

yes I am using bootstrap here

[split steeple]

I’m running it locally, only shows the html

[near pendant]

have you added '{% load static %}' on top of the html file ?

Hello, i have a question. I am coding food ordering website (django) and right now i have done orders for nonregistered users (via cookies), but now i need to create orders for registered user. How should i do that ? i need cart (stored in cookie for nonregister) to vanish when user logs in and load his saved cart (dunno where to save this cart) and when we logs out load the cookie as he is nonregisted one. Is there a way how to do this somehow ? Thanks

[past cipher]

remove the cookies when he logs in ?

[uneven wren]

oh yea sure, but i dont know where or how to save logged user cart (i dont want to save every orderItem in database on "add to cart" button click)

[edgy isle]

Ive said this multiple times(Not trying to sound rude in any way), there is only one disabled element every other one is not disabled and they also return None.

[past cipher]

are the other elements just basic input type text though ? whats the chrome post data saying ? also can you send your whole form element ?

[past cipher]

i think maybe db is the best, because they could switch devices and you'll want them to have their cart. just update the cart in db when they add/remove

[edgy isle]

let me get the full form element and be code

[past cipher]

@uneven wren just post to the db in the background so you don't have to refresh the page everytime they do it

[uneven wren]

Sure i will save it to database later, but i dont think its good to make request to db everytime logged user clicks on "add to cart" i was thinking to save it to session somehow

[edgy isle]

okay ima make a paste nvm thats way to large

[past cipher]

!pypaste - nvm forgot what its called

[edgy isle]

!paste

[lavish prism]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[past cipher]

but how you gonna know when they exit the browser ?

I think you'll have to query the db when they click add to cart, I may be wrong but I don't know another way

[uneven wren]

that is true.. session will vanish when i will close browser right ?

[past cipher]

depends if the cookie has an expiry

[uneven wren]

i was thinking about second cookie but that is not possible right ?

[past cipher]

look into onDisconnect

maybe you could try use that

[edgy isle]

Also the API responds with

[SQL: UPDATE ban SET username=?, userid=?, images=?, reasons=?, banstart=?, banend=?, notes=?, appealable=?, bannedby=? WHERE ban.username IS NULL]

[past cipher]

why are you using a third party to do the request ?

the request is done when the user clicks submit - nvm i see this is another request after you get the data, i think?

[edgy isle]

And the return from update/ban does

http://127.0.0.1:5000/edit/ban?name=None

As the URL instead of

http://127.0.0.1:5000/edit/ban?name=test

[edgy isle]

What happens is the form sends to /upload/ban and then the route for /upload/ban sends a request to a API

Idk WHY I DID THAT WAY

But I think its because of something I encountered with the actual adding and not editing

[past cipher]

can you open console in chrome, go to network, submit the form and check the data is actually being submitted correctly

instead of using request module, you could create a function somewhere, call the function, and then send the data

[edgy isle]

I just prefer using request module

SOMEHOW IT WAS THE DISABLED???

I swear I tested it without it

already

I just

Thanks for your help anyways @past cipher

wait

nvm the API is still having issues

its still saying

[SQL: UPDATE ban SET username=?, userid=?, images=?, reasons=?, banstart=?, banend=?, notes=?, appealable=?, bannedby=? WHERE ban.username = ?]

give me a second

ok fixed it

I am

whatever thanks @past cipher

@native tide Do you want to work on a project together? I got 4 down, looking to do one more maybe a bit bigger, take a look at my portfolio, www.christianlfonts.com

[toxic flame]

Hello, so on django it's really specific on the url addresses, for instance if you put login/ the address has to have a / on the end for it to work, is there a way to support both? without a / and with a /

[haughty turtle]

@toxic flame the reason it's like this is because when you use a web deployment software such as Apache or Ngingx you will notice that the / at the end means that it's a directory. When you have something without a / it means that its looking for a file.

[toxic flame]

So, is there no way?

[vestal hound]

@toxic flame the reason it's like this is because when you use a web deployment software such as Apache or Ngingx you will notice that the / at the end means that it's a directory. When you have something without a / it means that its looking for a file.

If I am hosting my django site on heroku do I need to change the data base from sqlite to postgress or something?

[native tide]

Hello who know django very good ?

[near pendant]

sqlite is good for websites with smaller number of users

[eternal blade]

But, is it necessary to change to what heroku offers?

[near pendant]

Do you know how to migrate to Postgre ?

if you know then you can keep it however you like, if you don't then you should learn cause, most web apps would use something other than sqlite

[eternal blade]

No...but can learn

[west wren]

Through separate API calls. This is purely for showing a navbar for guests (a landing page) and a navbar for users (with the appropriate links).

If they click on a link, they will have to then further provide authentication to have it be populated with their user-specific info

Hello i used a script to scrape instagram comments from a post but it's only scraping 25 and the post has 600
Help please ?

[gaunt marlin]

@glad patrol set the modal as a form, when you click update on the list use jquery to update the form with hidden input type contain the id of it, after that just send the POST request to update with ajax

[glad patrol]

@gaunt marlin can you share any resource link or video

[native tide]

Sure, how are you going to know how to route some people's request to the guest API and other people's request to the user API?

[gaunt marlin]

@glad patrol here an example https://stackoverflow.com/questions/38961333/change-form-input-field-value-with-jquery-within-a-bootstrap-modal

your update button on the list should have attribute with the id of the object row id, on button click pass that id value to the modal

[glad patrol]

thats the problem

i cant get id of the row

[gaunt marlin]

i passed the data-id attribute from button to the modal

[glad patrol]

pls come to dm

Hey guys! I want to build a real-time candle stick chart. My backend will be Python and Django, but I know Django is not good at styling. And I am a beginner for front-end language and web-development, so I get struggled for choosing the JS framework. I want to ask which framework is better for combining with Django. Vue, React or Angular?

[gaunt marlin]

$('.btn-rating').click(function (event) {
        event.preventDefault();
        $("#rating-form").attr('data-class-id', $(this).attr('data-id'));
    })

there this is more simple @glad patrol

[glad patrol]

ok this will only get the id form each row

[gaunt marlin]

yes but it pass the value in the form/modal i have

please anyone?

        cleaned = [obj for obj in data if not hasattr(obj, 'is_default') or not obj.is_default]
        self.model.objects.bulk_update(cleaned, ['position'])
        for instance in cleaned:
            # we trigger signals manually because django doesn't do
            # the same for us during bulk_update
            post_save.send(sender=self.model, instance=instance)

this is what I am doing.
For every instance in the for loop a trip is taken to the db for post_save.send

why? Can I reduce this?

hey guys, I used Flask, now I'm ready to move on

what's the best way to learn django

[dreamy anvil]

Does anyone know what's the best way to inspect the value of variables while a flask app is running in development mode using PyCharm?

[past cipher]

@dreamy anvil

what do you mean

why not just print the variable

[dreamy anvil]

I mean a flask app that's actively running

[past cipher]

i don't think you can inspect the element of a backend variable while its running, unless you stop it, add in print statements on the routes where the variable is, based off what you're sayng anyway

[dreamy anvil]

Shame

[past cipher]

what is it you want to do exactly

[dreamy anvil]

it's a quite complex API and it would be impractical to have a verbose mode because it would have to print so much

I want to be able to inspect variables in an ad hoc fashion

similar to how if you have a console open in pycharm you have the menu which shows all the variables

like that but for a script that's actively running basically

hello how can i get the ip adress of an user with flask ? I tried request.remote_addr but it's give the wrong ip ... sorry for my english

[native tide]

Are you using a reverse proxy?

You might need to read the IP from X-FORWARDED-FOR

[neon isle]

cloudfare

[native tide]

https://support.cloudflare.com/hc/en-us/articles/200170986-How-does-Cloudflare-handle-HTTP-Request-headers-

X-FORWARDED-FOR is the right header to use

[neon isle]

ok thx

[neon isle]

Now it works but it gives a string with two Ip
It's normal ?

[native tide]

In the examples above, 203.0.113.1 is the original visitor IP address and 198.51.100.101 and 198.51.100.102 are proxy server IP addresses provided to Cloudflare via the X-Forwarded-For header.```

So the first IP address is the visitor and second is the proxy server.

What you using the IP address for?

[native tide]

Also remember, that with IPv6, you could end up with a situation where you only have the proxy server for X-FORWARD-FOR and then you will find the IPv6 in Cf-Connecting-IPv6

[neon isle]

Ok

Thank you

with flask, is there a way to have a route with the same name for a different request method like it is with expressjs?
eg what i want is

app.get(() -> {});
app.post(() -> {});

instead of

@app.route("/route", methods=["GET", "POST"])
def route_func():
  if method == "POST":
    # do X
  elif method == "GET":
    #d Y

[native tide]

Does flask support Class based views.. then you could have methods for get and post.

I know Django has that ..

[surreal thicket]

can someone help me name something? i have a list of 50 categories, and each user in my application can choose to subscribe to one or more categories. i need a name for "the list of all categories, with a true/false flag on each category, identifying whether the user has subscribed to that category".

so this would be a resource like /users/{user_id}/categories-with-selections , i just need a good name for categories-with-selections

trying to balance verbosity with clarity

[native tide]

Subscriptions?

You could also call it Notifications, if you put a bit of text just saying that the notification will be a push or marketing message for the category 🙂

[surreal thicket]

these aren't notifications specifically

it's more like a "selection"

something to show on the user's home page

[rustic pebble]

Subscriptions seems fitting @surreal thicket

[surreal thicket]

heh, maybe i didnt explain clearly

i will have one resource that returns a list of category IDs

and another that returns this list of all categories, annotated with whether the user has selected it

so i have

/users/{user_id}/preferences/tags
    User's list of selected tag IDs
/users/{user_id}/preferences/???
    All tags, with {..., "selected": true} if the user selected it

you all still think "subscriptions" is the way to go?

[rustic pebble]

no

you should have this

/users/{user-id}/preferences/tags/ids
/users/{user-id}/preferences/tags/selected

So no need for adding the extra {"selected": true"}

@surreal thicket

[surreal thicket]

ah

well... this is a specific request from the frontend 😦

they want it all in 1 request, i know it kinda breaks the REST model but it's a performance consideration

[rustic pebble]

well i would still go with that, just add the {"selected": true} part

[surreal thicket]

ah

noted

i like that

[rustic pebble]

well it makes the most sense tbh

[surreal thicket]

would you have /users/{user-id}/preferences/tags return anything as well?

[rustic pebble]

hmm, it depends, it could return all tags, selected and unselected

[surreal thicket]

even though it's on the user resource?

we will definitely already have top-level /tags for that

[rustic pebble]

well then /users/{user-id}/preferences/tags should not return anything

[surreal thicket]

this is actually one issue i've had with the rest model as i start to learn it on a professional level, seems like you could have multiple endpoints all doing the same thing

[rustic pebble]

what framework are u using?

[surreal thicket]

as a hobbyist who cares? but designing apis for longevity is hard stuff

my team is using tornado

[rustic pebble]

Hmm

Well here is the thing

[surreal thicket]

nothing specifically rest-oriented, the rest part is somewhat of an organically growing layer on top of the tornado stuff

[rustic pebble]

I am guessing this is a big project, correct?

[surreal thicket]

yes

and i come from the data science world so professional web dev is somewhat unfamiliar territory to me

[native tide]

Hi

😭

[rustic pebble]

I am working on a huuuuuugeee project with some other devs, mainly frontend ones, the frontend is based in react

and I am using a microservice structure for the backend along with another dev

If you are multiple backend devs then building something under a monolith can result to things like this seems like you could have multiple endpoints all doing the same thing

Also really hard to scale properly as it scales linearly

Just my input ofc

[surreal thicket]

this is actually for one of our microservices 😛 or is rest for microservices is considered an anti-pattern?

[rustic pebble]

No its correct

Alright, then you probably have multiple endpoints in different services that give the same or similar responses

right?

[surreal thicket]

right now, no. we don't have a standalone tags service yet, and users only come from 1 place

so all of these endpoints i described, for now, would be under my purview in this one service

[rustic pebble]

Hmm, that is not correct

You should have everything user related under one microservice

[surreal thicket]

tags are applied to content, and users can select their list of tags for filtering content by default on their homepage

so tags aren't just for users

[rustic pebble]

Because if what you are building contains routes for other things, and they are used all the time then the route u mentioned earlier will get delays for no reason

Oh i see what you mean

Still, you should have different endpoints for these

If this is for a social network then this is our approach on a similar thing:

Everything user related stays within the user related microservices
Everything home page or content display stays within their respective microservices, even if that means that some endpoints are pretty much the same

They serve a different purpose thus they are listed accordingly

[surreal thicket]

right, that much i understand

[rustic pebble]

Question: Are you using a message broker to talk internally?

like redis

[surreal thicket]

what about something like this? /tags?user={user_id}

heh, that's a separate issue...

[rustic pebble]

You would clot the /tags endpoint, but you can do it for sure. No param means all tags are retrieved, else they are user specific

[surreal thicket]

that was what i was thinking, yes

what do you mean by "clot"?

as for how our backend is set up:

• tags are stored in our CMS, which has its own API
• users are stored in a database hosted by a cloud provider
• the microservices are running in hosted kubernetes with istio

[rustic pebble]

Basically both user specific and general calls would be made to the same endpoint

[surreal thicket]

ah, yeah

is /tags/by-user/{user-id} not rest enough?

[rustic pebble]

I am hoping this

:

You are not loading the tags each time from the db

Cause, if you are then that will be heavy asf once that route starts getting attention

[surreal thicket]

😅 yes, we can cache the list of tags

[rustic pebble]

I wouldn't cache them

well i would

but in redis

and load them with a background task from the cms api

That way you can access them globally

[surreal thicket]

the list of tags will change very rarely and the cache can be invalidated manually. but unfortunately i don't have the ability to run a message broker, unless i run it inside the container which seems to be somewhat pointless

[rustic pebble]

since u are using k8s, it still hasn't dropped docker in its public version i think, you can run redis as a service

[surreal thicket]

oh, is it going to drop docker at some point in the future?

[rustic pebble]

Yes, they have announced it

[surreal thicket]

it's all cloud hosted/managed anyway so i assume we will still have docker access

[rustic pebble]

Not sure, but you should think of your microservices architecture more

The need for a message broker is big

[surreal thicket]

trust me, i want to. i just joined this team and they've been working on this all somewhat independently from each other

dev A works on service 1 and dev B works on service 2, and they sometimes meet to discuss things

[rustic pebble]

well that's how it should be, but isn't there a general plan of how things talk to each other

[surreal thicket]

right. ive been trying to get more broad architectural discussions going and avoid snowballing cruft & tech debt, but features must be delivered in the meantime

[rustic pebble]

Before we started our project we spent weeks discussing it

[surreal thicket]

i will float the message broker idea, the team is pretty open to new ideas but short on time to "experiment"

[rustic pebble]

I mean, it is really easy to use

And it will help you solve a lot of problems

mainly cause its blazing fast and can you can load pretty much everything on it

then just have background services updating the db through redis

[surreal thicket]

noted, i have worked with applications that use redis but never used it myself

a year ago i was doing machine learning, and now here i am in the web dev trenches

[rustic pebble]

Haha nice, I have only done web dev

mainly backend

I got some really good frontend devs in my team

so i handle most of the backend myself

[surreal thicket]

its nice to be doing something that i dont know much about and am constantly learning, and i appreciate the advice

[rustic pebble]

well web dev is easy to learn hard to master

[surreal thicket]

also its funny, so many people try to go from dev to ml, i did the opposite, although mostly out of a sequence of coincidences and weird life choices

so i see, there is quite a lot to keep track of in order to do things right

[rustic pebble]

Haha, in a production environment it is entirely different than dev

But yea ML is on my to-learn list

i have it in the 4th semester of my uni as well

I learnt web dev completely by myself

[surreal thicket]

i've actively avoided going into #data-science-and-ml or any of my usual stats/datasci/ml chatrooms because i was getting burned out. but one day im sure ill be able to help advise you on it 🙂

[rustic pebble]

I asked some questions here in my early steps but i haven't gotten much help since then, i mostly reply to questions and not ask hah

[rustic pebble]

awesome, i will make sure to ask them then haha

Also, I got one more question for you

Since you are building a microservice why are you using tornado?

Is this what you know best or are you forced?

[surreal thicket]

forced 🙂

the microservice architecture was already set up when i arrived

and tornado was already chosen for the web framework within each backend python service

i should also note that we are trying to transition to graphql, which at least solves the data modeling problem, if not the query performance/bottleneck problem

we already have a graphql service running on top of everything but not everything is exposed through it, so we have lots of frontend stuff hitting the rest APIs and not graphql... its a bit of a mess

[rustic pebble]

GraphQL is insanely good if u get it right

I am still trying to learn it but we will transition to it soon

[surreal thicket]

{
  user(id:1234) {
    tags {
      id
      display_text
      selected
    }
  }
}

this would be the ideal world for me

well... actually no

same problem

inversion of whether "tags" or "user" is the top-level thing

{
  tags(user_id:1234) {
    id
    display_text
    selected
  }
}

hm

[rustic pebble]

That sounds the best to me

[surreal thicket]

👍

would it be better to do tags/{user_id} or tags?user_id={user_id}?

since for now i have to just do it in rest and worry about graphql later

[rustic pebble]

Go with tags?user_id={user_id}

Hello , I am thinking of learning Django framework, what all should I know before starting to learn Django?

[surreal thicket]

i think you should have at least a basic understanding of:

• OOP and python classes
• how a relational database works (like postgres/mysql/sqlite)
• how a URL is constructed
• HTML

I need help in heroku hosting

[visual wolf]

Thanks, I am familiar with all the above mentioned except the URL construction, I should check into that, thanks

[surreal thicket]

i just mean understanding the basic parts of a URL: scheme, domain, path, query

Hello guye i am new to web development. I have some experience in HTML and CSS

which lib should i use for python web dev? Flask?

[native tide]

Depends - how hectic is your project.

Django is great for when you need an admin and storing data

Flask is great for, I feel and some may disagree, more pure play API endpoints 🙂

Hello

How can i set cooldown on submitting form in django?

[wraith cypress]

hey, anyone have a good source to learn web sockets or socket.io stuff?

[native tide]

@wraith cypress learn for fun or learn to integrate into your current software?

Cloudflare have a good chat example of Websockets https://blog.cloudflare.com/introducing-workers-durable-objects/

[wraith cypress]

to integrate to django specifically

but I could use anything helpful on the topic in general

[native tide]

If you are willing to pay a bit, I recommend https://pusher.com/

Super easy, I did it in like 3 days for a real time barcode printer

because you can make normal REST API requests to Pusher - which sends the WS messages

[wraith cypress]

will check it out, thanks!

[native tide]

The problem with websockets at scale, is actually loadbalancing cause you can;'t move sessions between normal LBs - so over time, some LB's might get super hot and others super cold

Hence get Pusher to do that hard work of managing the actual Websockets

[wraith cypress]

so you think it's worth it since you pay for getting rid of the headaches of websockets and have to think less about them

[wraith cypress]

also how's the latency with it?

[native tide]

Well, I was EU - EU - so about 1.5x slower than what I would expect a REST call

but the nice thing - you deliver to Pusher, you can kind of stop having to send that data.

So if it's a big message, and the client has a slow connection - not your issue

[wraith cypress]

nice, thanks for letting me know about it

[native tide]

Also, they got SDK for iOS, Android and React 🙂 Sweet
