[nimble epoch]

did you try this User=www-data?

[summer grove]

it doesnt change anything setting it to that

[nimble epoch]

i have no other options i searched and i got these. hope you can find it.

[summer grove]

lmao thanks anyways yeah ive been working on this one issue for a while

[summer grove]

does anyone else have experience with sock files and gunicorn?

[solar ridge]

Hey, what package managers are suitable for a Django project on Windows to keep track of JS/CSS libraries? Bootstrap, jquery, etc.

Currently my entire python project is managed through virtual environments and git, but of course PIP was not designed for the external HTML'esque libraries.

[calm plume]

If you're okay with learning a syntax that's kinda different from both JavaScript and HTML - Pick React.
If you want to stay with something that's more like normal HTML - Pick Vue.

[summer grove]

@solar ridge I dont usually use package managers I just either download the files to a directory or link to a cdn

[calm plume]

Things like npm or yarn (a wrapper for npm) are the best ways to download js packages

You'll need to have node.js installed, and if you run npm init, it'll autogenerate a package.json that sorta like a Pipfile or a pyproject.toml

[calm plume]

May I ask why? Using things like npm makes it easier and compresses it, does it not?

[summer grove]

@calm plume I may have used it in the past but I've never really had the need to since most of the time the only packages I use is bootstrap and jqueyr

jquery

[calm plume]

Ah

Well if those are the only two packages, that makes sense

[summer grove]

hey @calm plume do you know anything about setting up django on a production website?

[calm plume]

No, not really. I know Django basics, but I haven't gotten too far into it.

[summer grove]

oh damn

setting up the production is a pain in the ass

[calm plume]

Check out https://git.pydis.com/site, it's a Django website in prod

[solar fulcrum]

Hi guys!
Is there a way to grab the text content of any generic webpage, with python (beautifulsoup)?

[vestal hound]

not in general

because you can’t run JS

[solar fulcrum]

even using a webdriver like Selenium?

[inland oak]

Yummi. Thanks.

[vestal hound]

then yes

[solar ridge]

Thanks @summer grove & @calm plume

[prime ruin]

Hello, I've got an issue with django and URLs taken from database. I have code as follows:
<a href="https://{{ finding.permalink }}">website</a>
Within finding.permalink there is specific URL for website taken from database. In this example, urls starting with www. like www.google.com will let you go to google website, but when url in database starts with http:// or https://, it will result in incorrect url appearing on the website (http://http://www.youtube.com). I already tried googling this issue, but I'm unable to find anyone with similiar problem. Earlier I have used <a href="{{ finding.permalink }}">website</a>, but that resulted in user being redirected to subpage of my website.
How can I solve this issue?

[native tide]

Hi guys

[solar fulcrum]

in that case, how can you identify page text content from all the rest, without using class tags, etc? the purpose is automatic summarization

[nova storm]

u solved it?

[quick cargo]

Use get_source i think it is from the webdriver

Then use regex to loosely remove all the html tags

Probably the easiest method

[prime ruin]

@nova storm Nope

[plain iron]

How can I can change a background colour of website in (HTML)

[calm plume]

In your css file, you can apply background-color to the html tag. Example:

html {
  background-color: "#0a2540";
}

[plain iron]

Will it wil change the colour of the full page

[solar fulcrum]

thank you. I'll do that then.

[calm plume]

Yes

[radiant storm]

I use Django and Django Rest Framework to create simple REST applications. I know the basics. But I have no clue what bigger than just simple CRUD applications I can make.

I'm looking for inspiration guys.

I have no idea what projects I can make that would keep my motivation to learn alive.

[dawn heath]

https://stackoverflow.com/questions/67422152/how-do-i-force-celery-apply-dynamic-times-chained-tasks

[radiant storm]

I have no motivation and eagerness to study Django and Django Rest Framework documentations when I don't have any bigger projects in mind.

[signal bronze]

should i use flask with react or is it not worth it? I mean i've been trying to set it up and its a pain

[calm plume]

React is great, but idk how it is with Flask

[inland oak]

I would say Django Rest Framework or FastAPI is better than flask

To work with React

Flask is better recomended for beginners in python frameworks though

Purely out of leaning experience

[signal bronze]

I like how much control i have with flask vs other frameworks

[thorn igloo]

how though?

[inland oak]

They are battery-included frameworks
A lot of stuff is already tuned for you.
Helps to make twice less errors, and having twice better quality

[thorn igloo]

i currently use it with vue so i don't see the problem

[inland oak]

Django is good with premade admin site and good ORM for databases, which works great for migrations

FastAPI has self generated api wikis out of the box. Which helps to coordinate with front enders easier.

[signal bronze]

What is vue like vs react. I know i should be using google for this sorry. Also what is it like with required assets? Like with react there was aton of files that had to be there and some config i had to setup

[thorn igloo]

what do you mean by required assests?

[thorn igloo]

what am i looking for specifically

[signal bronze]

just all of them

[thorn igloo]

here*

[signal bronze]

i like having my project very clean

[thorn igloo]

but uhm, i think it literally depends on what you add

[wooden ruin]

i'm a really big fan of djangorestframework-simplejwt, because they make using DRF with authentication tokens really easy, and it allows for things like users accessing an api only if they are authenticated

[topaz finch]

I am making an object that would take a request object from various web frameworks and standardize it a bit. Many frameworks have a url method to get the full URL of the request. How could I get this from a Django HTTPRequest object as well? Didnt see anything in the docs.

To anyone already typing "why are you doing this, just dont" or anything like it, I am doing it mostly as a fun little project because why not, so please dont go there.

Please @ me when responding.

[vital pagoda]

now this is not a web dev question more of a hosting in heroku question

basically i completed a project which is a telegram bot which requests like 300+ websites and returns data to telegram and now id wanna host it in heroku but this server should run 24 x 7
so im not sure which plan to decide upon

[void spade]

Hey so im trying to find a simple django api with sqlite tutorial. Any recommendations?

[thorny rover]

djangos documentation is really good

[void spade]

Thats what im currently reading, thanks!

[opaque rivet]

If you're looking to make an API, use django-rest-framework:
https://www.django-rest-framework.org/topics/documenting-your-api/
Pretty printed on youtube does good videos on it.
Django has sqlite3 out of the box, so you just need to learn how to use the django orm (from the docs) 🙂

[thorny rover]

so i have an editable, searchable table that auto populates from a csv, how would i make it so if a user edits a cell then clicks the button in the top right, it applies those changes to the csv

[topaz finch]

Anything on this?

[surreal portal]

I confirm. I've been trying to get the hand at Flask-Restful, and botting up the Swagger UI is such a pain. I'm thankful FastAPI exists.

I'm saying that and my first API under Flask was getting the hand on two basic routes by simply using jsonify and the requests package to handle payloads and responses

I meant to ask about Flask-Migrate. Supposing I have a Flask app using SQLAlchemy with a MySQL database, an __init__.py file in which I declare the create_app() factory function, which initializes the database and a Migrate object, does that mean I can use flask db init right after I lauch the app, or do I need a manage.py file?

[thorn igloo]

i have the same setup and it works without the manage file

[prime shuttle]

i'm trying to add a search bar in my website does anyone know how to do that

[calm plume]

Depends on your website content

What kind of code does it have?

HTML?

[prime shuttle]

rn i just want the search bar to appear and reroute to a blank page or something

yea

it has html

and css for the style

[calm plume]

So you're not asking how to implement search

You're asking how to make a search bar?

[prime shuttle]

yea

i'm a complete beginner lol

[calm plume]

Then you can just make an <input> element

Inside a <form> element

[prime shuttle]

where would I do that?

[calm plume]

On whichever page where you want the search bar

[prime shuttle]

ok thanks

[prime shuttle]

what is Blogpost.objects.filter

when I put it in my code it says blogpost undefined

i've seen it on a couple of other different videos

[terse vapor]

Flask-admin's view and edit function are usually like this

admin.add_view(ModelView(User, db.session))```
But how can I add like a `@login_required` thing so only user can see it?

[crude glade]

https://flask-admin.readthedocs.io/en/latest/introduction/#authorization-permissions theres a couple ways of authenticating

[pliant birch]

will i get help in javascript here too?

[naive crater]

not the best place, but I'm sure someone here knows it. something like https://discord.gg/code would be better though

[vital pagoda]

what hosting service does the python site use?

[green snow]

im making an assigment submission webapp for uni project
i need to copy paste the content of an upload to google and fetch the relevant links and display it on mywebsite
can i do this with beautifulsoup?

[inland oak]

yup

beautifulsoup or xpath for web scrapping works

[green snow]

but how do i sendkeys?

[inland oak]

why would you need sending keys?

[green snow]

like a student uploads a pdf

text is extracted from it and it ios compared to documentts submitted by his classmates for plagiarism

so i also want the content to beasearched over the internet

[inland oak]

scratching head
I have no idea how this 'pdf uploading' is supposed to work

btw, you could check perhaps Google API

[green snow]

its simple

[inland oak]

perhaps it has what you want

[green snow]

ill send a snip

[inland oak]

perhaps you are speaking about 'selenium' level functionality

[inland oak]

it can imitate actions of a real user

[green snow]

so we cant do it with bs4?

[inland oak]

nah, bs4 is meant just to extract results

[green snow]

see this is a page from my webapp ,the teacher can view all the submission of students she wil;l get alist of smimlar uploads

[inland oak]

from DOM mess of a resulting page to some format you need

[green snow]

also i want to check the contents of the upload online

so i have to use selenium ?

[inland oak]

you can check whatever you wish, if it would be uploaded first at your backend server

[green snow]

ya it is uploaded to the server

this is django

[inland oak]

depending on where you want to upload your pdf

if to your own django, then it can be done just with internal django tools

if to not your own site, some foreign service, then possible need for selenium

if to some foreign API, all you need a regular request with JSON body inside

[green snow]

no

see if u were my teacher

and i have to submit to u some case study

to check if i have copied from the internet

u would copy paste the content of the pdf to google search bar to see if i have stolen it

i am trying to do that

[inland oak]

then all you need

uploading pdf to your own django web site

it can be done without seleium or anything else

just use Django available tools

and then make request to necessary google url

[green snow]

i have done this

[inland oak]

with content you wish to find

and then beautiful soup results out of it

or actually better connect Google API

and make request to it

it will return to you JSON results

it would be nicer than beautiful soup

because you would not be blocked by captchas

[green snow]

i hv very less time in hand

i hv selenium experience

and bs4 only , but not with any API or django requests

[inland oak]

no need to use Selenium in this situation in my opinion

[green snow]

so with django u can send keys?

[inland oak]

you can possibly use it for that though

but it would be overkill

[inland oak]

just make

import request
request.get(f'{GOOGLE URL CONTAINING WHAT YOU WISH TO FIND}')

it will make request without key usage

or as I said find Google API

and learn how to use it

interface to communicate with it, will be the same almost

it will return just nicer results, which you don't need to parse with beautiful soup

[green snow]

tysm

[green snow]

request.get(f'{contents of thr pdf}')

will work?

[green snow]

https://youtu.be/dyUhGZ6iNTc

which python web framework you know ?

[near ravine]

Hi, I'm making a software in Python which makes PDFs into Audiobooks. I wanted to use it for my blind grandpa so that he can read any book he wants to. I need help with 3 things.
`1- I'm using a module called Tika and as you may or may not know, when made into an exe, it requires Java to run. Now I don't want my friends and whoever else installs it to also require Java, I wanna make it look professional. So is there an alternative?
2 - If I use gtts, it does do all languages but the voices suck and pyttx3 sapi5 needs users to install voices and go into the windows registry to change/ add them. I can't exepect others to do the same. So i want to add good tts voices for it.
3 - Deployment: This one's tough. I figured out how to make an exe, but I want it to be a webapp. But making a webapp is tough(have tried) and i need a better quide how to make one.
If anyone can help me with these 3 issues or give advice, you're more than welcome

[surreal portal]

Hi. I'm looking forward to mine PDFs (without using Python packages as PyPDF is a bit outdated and I don't want Java to run as a backend either) and so far there's not a universal solution that works well for PDFs.

My strategy was extracting text, images, formulas into separate folders but the mining can act differently depending on the pdf version. So if anybody has dug further on pdf structure research I'm interested too

[obsidian cairn]

What u mean, Im a noob and don't know what I am doing

[toxic echo]

in django, do you use a single app with everything or split into multiple apps

[inland oak]

in general, a single app for one db model

or more like.... one app for one db model that matters

ask yourself this... will be those objects different in db model, views, urls, testing, programming logic and etc
if yes, you are definitely needing separating them to different apps

How do I add a confirm_password field to my CustomUser model?

class CustomUser(AbstractUser):
    pass

[frozen wren]

Flask? Django?

[native tide]

It's Django

I did py class CustomUser(AbstractUser): confirm_password = models.CharField( max_length=100, blank=False, null=False) But it says this ```You are trying to add a non-nullable field 'confirm_password' to customuser without a default; we can't do that (the database needs something to populate existing rows).
Please select a fix:

1. Provide a one-off default now (will be set on all existing rows with a null value for this column)
2. Quit, and let me add a default in models.py

Why would a password need a default? Passwords shouldn't be default

[thorny rover]

                    });
                </script>```

[frozen wren]

You don’t need to have confirm_password? It would be automatically assumed.

[plain iron]

How can I can print an image in a website in HTML

If any one can help!

[frozen wren]

It’s <img src=“file location” width=x height=x>

[frozen wren]

Where x is what you want the size to be

[native tide]

In my models.py file here```py
from django.db import models
from django.contrib.auth.models import AbstractUser

Create your models here.

class CustomUser(AbstractUser):
confirm_password = models.CharField(max_length=100, default='')

class Loan(models.Model):

APPROVED = 'APP'
REGISTERED = 'REG'
EXPIRED = 'EXP'
REQUESTED = 'REQ'
REJECTED = 'REJ'

STATUS_CHOICES = [
    (REGISTERED, 'Registered'),
    (EXPIRED, 'Expired'),
    (REQUESTED, 'Requested'),
    (REJECTED, 'Rejected'),
    (APPROVED, 'Approved'),
]

borrower = models.ForeignKey(
    'CustomUser', on_delete=models.CASCADE, related_name='borrowers')

lender = models.ForeignKey(
    'CustomUser', on_delete=models.CASCADE, related_name='lenders')

date = models.DateField(auto_now_add=True)

status = models.CharField(
    max_length=3,
    choices=STATUS_CHOICES,
    default=REQUESTED
)

def str(self):
return f'#{self.id}'

How do I make it impossible for them not to be the same user?

Cuz in the api page In the HTML form I can set them to be the same. I don't want that.

It shouldn't be possible

[frozen wren]

Did you get it to work?

Like, i have a bunch of numbers 20, 38, 14, 43 in db. And wish to render it in template by decrease => 43, 38, 20, 14
Django could do that with any filter or i have to filter it with python before render in views?

Lol, nvm, i could use order_by in query. Sry for stupidness. =|

[terse vapor]

In flask stringfield, when i try to input a name or a number, there's always a few recommendation for me to input, is there any way to block it?

[crude glade]

you can try something like this
{{ form.var(autocomplete="off") }}

[terse vapor]

ok ok

[crude glade]

there might also be some css to do something similar

and if you're using chrome, it tends to ignore passwords so you can try
autocomplete="new-password"
instead

I want to get data from a backend api

But It gives me this errror: loansList.jsx:20 Uncaught TypeError: Cannot read property 'first_name' of undefined at LoansList.renderBorrower (loansList.jsx:20) at loansList.jsx:63 at Array.map (<anonymous>) at LoansList.render (loansList.jsx:55) at finishClassComponent (react-dom.development.js:17485) at updateClassComponent (react-dom.development.js:17435) at beginWork (react-dom.development.js:19073) at HTMLUnknownElement.callCallback (react-dom.development.js:3945) at Object.invokeGuardedCallbackDev (react-dom.development.js:3994) at invokeGuardedCallback (react-dom.development.js:4056) at beginWork$1 (react-dom.development.js:23964) at performUnitOfWork (react-dom.development.js:22776) at workLoopSync (react-dom.development.js:22707) at renderRootSync (react-dom.development.js:22670) at performSyncWorkOnRoot (react-dom.development.js:22293) at react-dom.development.js:11327 at unstable_runWithPriority (scheduler.development.js:468) at runWithPriority$1 (react-dom.development.js:11276) at flushSyncCallbackQueueImpl (react-dom.development.js:11322) at flushSyncCallbackQueue (react-dom.development.js:11309) at scheduleUpdateOnFiber (react-dom.development.js:21893) at Object.enqueueSetState (react-dom.development.js:12467) at LoansList.push../node_modules/react/cjs/react.development.js.Component.setState (react.development.js:365) at loansList.jsx:10
And the weird thing is....
When I spam the refresh button It works sometimes
And sometimes gives me an error

[opaque rivet]

because componentDidMount runs after the component has been rendered (and painted to the screen). Therefore at the start this.state.loans is empty and you have no data to .map through - so it's undefined

when you're spamming the refresh button, you're just hoping that your component made an API call before you refresh.

[native tide]

so do I put the function in componentDidMount?

[opaque rivet]

to fix this just add a conditional to your JSX, like:

{this.state.loans && this.state.loans.map(...)}

but note that this.state.loans has to be a falsy value at first, (you have an empty array - I don't know if that's falsy (I think it is) but let me know)

[opaque rivet]

no, because as I said, componentDidMount only fires after the component has been rendered. You are trying to .map through state before componentDidMount has fired.

so your state will be empty.

[native tide]

Yes it is falsy

By any chance, do you know how to make a loading screen?

before everything renders?

[opaque rivet]

you can use a ternary operator:

{this.state.loading ? <LoadingComponent /> : this.state.loans.map(...)}```
where `LoadingComponent` is the loading comp.

[native tide]

that simple?

[opaque rivet]

well yeah, you just have to handle the loading state and making the component (or importing it from some comp. library)

all sorted now?

[native tide]

no

it still gives me an error

[opaque rivet]

show us the code

[native tide]

[opaque rivet]

and what's the error

[native tide]

https://pastebin.com/EDNvyeNq

[native tide]

same one

can't read property first_name of undefinded

[opaque rivet]

in renderBorrower(id) print your state.users

this.state.users.find((user) => user.id === id); is not returning anything

[native tide]

okay now

the whole thing is successfully rendered as it should...

I also printed the users as you can see

but lets refresh the page

Now this

[opaque rivet]

because [] is truthy

[drifting furnace]

It is?

[opaque rivet]

so put your initial state as null

apparently so

[drifting furnace]

!e print(bool([]))

[lavish prism]

@drifting furnace :white_check_mark: Your eval job has completed with return code 0.

False

[drifting furnace]

Hmm it doesn't seem so

[opaque rivet]

https://stackoverflow.com/questions/19146176/why-do-empty-javascript-arrays-evaluate-to-true-in-conditional-structures

[drifting furnace]

Oh yeah I remembered

[opaque rivet]

that's python, this is JS

[drifting furnace]

You need to check if it's equal to [] to check if it's empty, not just boolean it

[native tide]

Im confused

[opaque rivet]

make your initial state this.state.loans equal to null so it's definitely falsy

then your state will be mapped through only once the state is available

because apparently [] is truthy

[native tide]

Same sort of error

but this time it's null instead of undefined

hi

http://cloudzeta.ml/

if you go here

it takes you to a directory thing

i use infinityfree for hosting

how do i fix it

[opaque rivet]

are you sure this const borrower = this.state.users.find((user) => user.id === id); returns something

oh I see

{this.state.loans &&
            this.state.loans.map((loan, id) => {
              const { id: pk, borrower, lender, amount, status, date } = loan;
              return (
                <tr key={id}>
                  <td>
                    <b>#579{pk}A</b>
                  </td>
                  <td>{this.renderBorrower(borrower)}</td>
                  <td>{lender}</td>
                  <td>${amount}</td>
                  <td>{this.renderStatus(status)}</td>
                  <td>
                    <i className="far fa-calendar"></i> {date}
                  </td>
                </tr>
              );
            })}

wrap the code on the right side of the conditional in parenthesis ()

[native tide]

this you mean? jsx {this.state.loans && (this.state.loans.map((loan, id) => { const { id: pk, borrower, lender, amount, status, date } = loan; return ( <tr key={id}> <td> <b>#579{pk}A</b> </td> <td>{this.renderBorrower(borrower)}</td> <td>{lender}</td> <td>${amount}</td> <td>{this.renderStatus(status)}</td> <td> <i className="far fa-calendar"></i> {date} </td> </tr> ); }))}

Still doesn't work.

[native tide]

help

[opaque rivet]

so that the parenthesis are on the same line as the conditional

and if it's not that then I don't know what the issue is

[native tide]

can someone help me, when i go to http://cloudzeta.ml/ i get a directory thing, but when i go directly to http://cloudzeta.ml/zeta/ it works

[toxic echo]

is there any way to link css files from a child template in django

sorry i dont know if child if the term
i have base.html with base.css linked in the <head> tag
i extend base.html from home.html and i want to link home.css in the same <head> tag

[silver moss]

Src

Link by using address of css

[native tide]

http://cloudzeta.ml/

new solution..

just telling people

to go to /zeta/

lmao

oh well im too dumb to fix it

[native tide]

@toxic echo if you extend the html file where you want the css from the base then you dont need to do anything. Its already inheriting. So if you link it in the css in the base.html its on all html files where you extend with base.html

[jovial mist]

Is it ok to store sensitive info in the session?

[opaque rivet]

in the session cookie?

[jovial mist]

Yes

[opaque rivet]

what sensitive info are we talking about?

[jovial mist]

The user's token

[opaque rivet]

yeah that's fine

[jovial mist]

Ok thanks

[pure gull]

cos unfortunately wordpress runs 40% of the web ;p

[prime shuttle]

does anyone know why this error shows I turned on allow all cookies on chrome

but it still shows the same message

[toxic echo]

yeah that would work, but i dont want to add css that i dont need on every page

[native tide]

@toxic echo You can make a block called css and then link on every page you need another css add it there and the one from the base for example gets overriden

[toxic echo]

ohh i will try that, sounds good

[prime shuttle]

nvm

figured it out

[wooden ruin]

how can I choose specific permissions per method on a modelviewset?

this is my PostViewSet create() method

    def create(self, request):
        permission_classes = [permissions.IsAuthenticated]
        try:
            user = User.objects.get(username=request.data["author"]["username"])
        except user.DoesNotExist:
            return Response({"message": "user with username does not exist"})
        post = Post(
            body = request.data["body"],
            author = user,
            likes = 0
        ).save()
        return Response({"message": "Your post has been saved"})

however i can still send post requests even if i'm not authenticated

i want to the user to only be authenticated on posts requests, but get requests should not need auth

[vestal hound]

IsAuthenticatedOrReadOnly

wow didn't think it was that easy. thanks!

[violet briar]

how do I inherit from multiple classes/prototypes in JS, kinda like multi class inheritance in python, what's the syntax for it, I am thinking about something like this:

class someClass extends (Parent1, Parent2) {...}

[native tide]

Does anyone know how to return JSON errors when there is an authentication error on Flask?
It's returning HTML and my JSON client is breaking

[vestal hound]

there's no multiple inheritance in JS

(basically)

you can implement multiple interfaces though

[violet briar]

well... that's inconvenient as hell, is there an alternative?

[vestal hound]

why do you want multiple inheritance

[violet briar]

because I want to create a child class that inherits methods from 2 parent classes

[vestal hound]

yes, that is what multiple inheritance is

but what I'm asking is

why aren't you using a pattern more appropriate for JS

for example...composition?

[calm plume]

JavaScript isn't isn't a class based object oriented language.

[violet briar]

what is composition?

[vestal hound]

that is something you can Google

[calm plume]

If you're using JavaScript, use JavaScript, not Python.

[vestal hound]

indeed

honestly, prototypical inheritance is weird for most people though

it's interesting, but

[calm plume]

But it's not the way here

[violet briar]

I mean, yes, classes in js are just a syntactical sugar wrap around prototypes

it's like giving needles to drug addicts

[native tide]

Does anyone know how to return JSON errors when there is an authentication error on Flask?
It's returning HTML and my JSON client is breaking

Flask RESTFUL btw

[violet briar]

hey, uhm, how do I implement something to python's __iter__ and __next__ methods in a javascript class to make it support iteration?

[vestal hound]

look into Symbol.iterator

[violet briar]

ok thanks

Hey can anyone help me on how to disable those HTML pop up validators.

I am actually using bootstrap classes on the flask validators and don't want those additional validations.

[thorn igloo]

can you show the html for the form structure?

but in essence, you basically need to add the novalidate attribute to the form

[violet briar]

does javascript have keyword arguments like python?

[mint folio]

Don’t set the field as required on your form

[nimble epoch]

yes why not

[distant charm]

Hello people

my css file is not working with my react app no idea why

trying to style bootstrap component

[calm plume]

Can you share the code?

And how you imported the css file?

[distant charm]

any idea what might be wrong?

[calm plume]

Can you share the relevant parts of the css file?

[distant charm]

it consists of these 10lines only```css
.card{
width:50%;
float: none;
margin-bottom: 10px;
margin-top:50px;
}

@media (max-width:991px){
.card{width:50%}
}```

[calm plume]

Can you try sticking a background color on .card? Just to see if it applies?

[distant charm]

ops my bad forgot one to set margin to auto 😮 sorry

Thank you so much for your time

[calm plume]

Good luck with your app!

Is anyone here good with requests?

[jade lark]

What's the question

[glossy arrow]

Hey guys

is there a specification for ASGI middlewares?

[balmy crane]

So

i'm trying to get access to a page, but it has a js loading screen

meaning that when i try to request the site

it returns the info about the loading screen not the actual site

heres my code

url = requests.get("https://robertsspaceindustries.com/spectrum/community/SC/forum/4/thread/weekend-playtest-fleet-week-expo-halls-javelin-tou/4006567")
soup = BeautifulSoup(url.text, 'lxml')
print(soup.prettify())

https://robertsspaceindustries.com/spectrum/community/SC/forum/4/thread/weekend-playtest-fleet-week-expo-halls-javelin-tou/4006567

theres the link

you can see it has a loading screen

[jade lark]

you'll need to intercept requests. If you don't know how to do that then you'll need to use puppeteer or selenium. The site might have security for it though.

I own a service for this specific case if you'd like I can send it to you. Can do up to 1000 requests for free and it does render JS as well.

Looking at the site the whole thing uses React.

[balmy crane]

Is it impossible to web scrape then?

[jade lark]

No, just harder.

You can use puppeteer or selenium.

[balmy crane]

How does your service work

[jade lark]

https://github.com/pyppeteer/pyppeteer
https://github.com/SeleniumHQ/selenium/

[balmy crane]

And is there a good tut for puppeterr/selenium

[jade lark]

Try this first

If there is security in place then it will be harder

[balmy crane]

OKay so just download theses?

are they packages?

I looked up some answers

from bs4 import BeautifulSoup
from selenium import webdriver
driver = webdriver.Chrome()
url = "https://shop.nordstrom.com/c/womens-dresses-shop?origin=topnav&cm_sp=Top%20Navigation-_-Women-_-Dresses&offset=11&page=3&top=72"
driver.get(url)
soup = BeautifulSoup(driver.page_source, 'html.parser')
driver.quit()
print(soup.prettify())

this is what i got from stack overflow

but when i try this, it tells me i dont have the chromedriver directory

[jade lark]

You'll need to download the webdriver

[balmy crane]

sorry im pretty slow haha

i downloaded chromedriver.exe

how do i put it in my path?

[jade lark]

alright good

[balmy crane]

Starting ChromeDriver 90.0.4430.24 (4c6d850f087da467d926e8eddb76550aed655991-refs/branch-heads/4430@{#429}) on port 9515 Only local connections are allowed. Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe. ChromeDriver was started successfully.

this is my cmd rn

[jade lark]

Did you figure out how to put it in your path?

you don't run it

put it into
C:\Windows\System32

drag and drop it onto there

then try and run your program

[balmy crane]

okay so it ran

and like a window opened up of the

website

but it still got info of the loading screen

[jade lark]

well yeah that will happen

cause the loading screen takes a bit

so

from time import sleep

sleep(5)

or something

[balmy crane]

sleep 5 where though

driver = webdriver.Chrome()
url = "https://robertsspaceindustries.com/spectrum/community/SC/forum/4/thread/weekend-playtest-fleet-week-expo-halls-javelin-tou/4006567"
driver.get(url)
soup = BeautifulSoup(driver.page_source, 'html.parser')
driver.quit()
print(soup.prettify())

[jade lark]

You should wait for an element but that might be beyond your scope atm

and after the driver.get

[balmy crane]

holy shit

it worked

wait

by wait for an elemen

you mean like wait for a specfic class to appear or something?

thank you so much bro

[jade lark]

Yeah exactly that

and no problem

[balmy crane]

Okay, i prop would need a bit more knowledge about how this driver stuff works

but would it kinda be like (sudo code)

While True: Try: Get Class then quit driver Except: pass

or something

[jade lark]

Nah it would be a method you call and it blocks the program until it either gets a response or timeouts.

Look at some tutorials or the docs for selenium

[balmy crane]

okay will do

thank you bro

have a good day

[jade lark]

You too!

so currently my search bar looks like this

any idea on how to make it look more appealing perhaps a larger search bar
with the search button connected to the bar
and a different colour

How does one submit html forms

anyone experienced with payment gateways?

how to add in a site a payment gateway and what to focus on?

[inland oak]

focus on security ;b

try checking Stripe for example, I don't know really it inside yet
I just saw colleague, who had it working in Flask in its testing mod
and then rewrote it to work for Django as well

[native tide]

yes exactly! Also working with flask

[inland oak]

going to research how it works on a next week probably, or week after that

its testing example looks working pretty easy

you can create special testing account there

and making testing payment as much as you want

in order to get grasp of that thing

[native tide]

I think motsly the integration is the most work, other than that the transaction are all on the gateway.

[inland oak]

mm there are two mods as far as I know

first one... you are using their system of things to buy, and basically you put everything on their shoulders

[native tide]

exactly

[inland oak]

in second approach you can create your own database with things to buy, and client system

and you just wire payments to their system

[native tide]

for every test though, the fees will go wild right?

[inland oak]

tests are free I think

perhaps some limit per month or something

[native tide]

this requires to make an arrangement with Stripe the company as well?like a subscription?

[inland oak]

it is available right after registration as far as I know

they give testing account/token access by default

[native tide]

nice

[inland oak]

the most important would be probably never exposing your private key ;b

there is also public key though, probably it is allowed for exposing

[native tide]

If I want to keep fees for myself for every transaction, this is complex?

[inland oak]

what do you mean exactly?

[native tide]

i mean additional fees from what Stripe will take.

[inland oak]

some fee would be probably for sure

[native tide]

like an app where people transfer money to other people and using Stripe gateway I also keep a small amount as the site owner.

[inland oak]

any payment system is meant in the first place to get money to the site owner 😉 well, or at least at the second place right after they would collect their fees

how much would you succeed to transfer money between two random people, is another problem though

it needs finding some solution

[native tide]

what are the problems?

[inland oak]

the problem to find a way to transfer money between two random users

I get it, that's what you wish to do

[native tide]

via a gateway?:)

[inland oak]

Stripe in the first place a way to collect money from users to site owner

[native tide]

it isn't about two separate bank accounts?

hmm

What can I use then for that purpose?

[vagrant owl]

Hi guys, need help.
Let's say I have a simple flask API and backend where I have some files in access and send data to the front-end from.

Any idea where I can get such an implementation?

When you program python, where do you program it is there a good app to use. besides pycharm?

[violet briar]

should I use px or should I use em / rem in CSS?

which one is better in terms of compatibility with different view ports on different devices?

[vestal hound]

use rem unless you have a good reason to do otherwise

because you generally want your UI to scale with the font size your user has set

[violet briar]

I mean, if the user wants to zoom they'll use their browser's zoom feature, no one zooms by zooming font

[opaque rivet]

Using px is just hard-coding your design, it'll harm the responsiveness of your site. Use rem.

[vestal hound]

most people don’t, yes

but they exist

and also

I personally find it easier to keep my design uniform

when everything is defined in terms of rem

so I went to do a bit of research because I was wondering about the browser zoom point

C:\essentials\python\python.exe: can't open file 'C:\Users\91834\PycharmProjects\website\manage.py': [Errno 2] No such file or directory```

im new to django

[jade lark]

There isn't a manage.py file in the directory you're running from @dusk portal

[pale mulch]

Hello, I'm a PHP Developer and learned Python, so I want to use this in Web, so can anyone please recommend me a Flask or Django course?

[calm plume]

The official Django tutorial is great, but it uses HTML

[native tide]

Hello

I need to get the text from an image url, cv2.imread but with an image url, i don't want to download the image

[pastel relic]

Hey! does anyone have any experience with selenium?

[jade lark]

Highly recommend going with Django.

[jade lark]

Try downloading the image as bytes (save it temporary in memory). Make sure the library can read information from bytes though.

[native tide]

I have tried that, but I don't know how to make it read the image.

[terse vapor]

?

[jade lark]

Literally pass the query parameter with it.

If that's not supported make a custom decorator or function.

[jade lark]

I haven't used opencv2 in a while so I won't be much help. I would keep looking into the documentation. If there isn't an option then you may need to download the image. You can always delete it after.

[native tide]

Okay thx

[languid raptor]

If you want a breezy read, you could try William Vincent's Trilogy Django for beginners, django for professionals, and django for api's. Short and sweet with a few best practices thrown in. Reddit's Django Learning community also recommends Two Scoops of Django, which I've found useful, but also ahead of just getting your head wrapped around the framework.

[wet dust]

What’s the difference between Django and Flask?

I picked up flask and I don’t want to learn django after learning flask

[languid raptor]

Django is the batteries included version of flask

[wet dust]

Because flask is doable for me

[calm plume]

Flask doesn't have a database abstraction layer or anything like that

[jade lark]

Django also does have a larger amount of packages that are maintained. It includes security, admin dashboard, migrations, orm, auth, emailing, and much much more.

Meaning you don't have to worry about as many small details. For example Instagram, Pinterest, NASA, quite a few more all run on some form of Django.

Just allows you to iterate and ship things fast.

[wet dust]

Hm - so should I forget flask and learn Django? Or is flask doable

Like is it fine or is flask bad

[jade lark]

Flask is fine.

[wet dust]

Alright great

[jade lark]

Flask is perfectly fine.

I started with Flask first myself and then moved into Django. As Flask does give you a different perspective of how things work.

[wet dust]

Free code camp has a good flask tutorial

On youtube

[pale mulch]

Ok, thanks everyone

[jade lark]

I recommend Corey Schafer
https://www.youtube.com/watch?v=MwZwr5Tvyxo&list=PL-osiE80TeTs4UjLw5MM6OjgkjFeUxCYH

[languid raptor]

@jade lark Speaking of packages--I'm having a time understanding django-wiki project. It's a module, so when you install it, you have a django project with settings and little else. What's the quick take on customizing a package like django-wiki (I want to add django-tagulous) when the whole project is inside a module?

[jade lark]

You can use class inheritance. So, you would make your own class and inherit from it. Override the methods provided by it.

[languid raptor]

@jade lark Ok. classes in what files? Do I create a new app for django-wiki and then add override classes there?

call it django-wiki-overrider

[wet dust]

What are you trying to do? Like specifically

[jade lark]

Nah don't do that

Create it where your application requires it.

If you're using it throughout multiple apps then created a utils module, then a file and class for it in there.

[languid raptor]

that's the whole application. just a wiki page. Django-wiki has everything I want except for tags

[jade lark]

Break it down further.

Does the wiki have authors, tags, posts?

[languid raptor]

its on github

[jade lark]

I know that

I mean for your application

[languid raptor]

duh. type fast. think slow

its for knowledge management for the office. <10 users.

but django-wiki doesn't support tagging. And I want to have an ontology of items for search. in other words, tags like SE

[jade lark]

Right perfect

so you would just make a tags app

[native tide]

hey, does someone here know a bit about javascript and wtforms?

[languid raptor]

Ok. My mental map ... make tags app and in there put the override classes for django wiki

[jade lark]

Then follow the customization docs
https://django-wiki.readthedocs.io/en/latest/customization.html

You would want to probably write your own views for this and include the tags, then include it in the custom templates.

so structure would be like

custom_app
  - tags
    - views
    - models
    - templates
  - settings.py
  - etc...

in settings.py you would include the django-wiki app from pip

Then if you're creating custom views for parts of django-wiki you would make apps and override them as required. For example, if they had an articles app. You would make one yourself and override it there. This will allow the code base to be much smaller and separated.

[native tide]

do you know something about flaskwtf and javascript @jade lark ?

[jade lark]

Yes, but if you can ask the actual question that you have that would be great.

[native tide]

i have a flaskwtf form in a bootstrap modal, but whenever i submit the form the modal also gets closed even when there is an error in the form

[silver tinsel]

Hey, can someone help me with flask?
i just followed a basic tutorial on how to plot a chart on a webiste and i have the exact same code now but i get an error when trying to load the website

thats my error and i guess you wanna see the code too 😄

[native tide]

i tried to find a solution but the javascript isnt working

[silver tinsel]

from flask import Flask, render_template

app = Flask(__name__)


@app.route("/")
def home():
    data = [
        ("1-01-2020", 1234),
        ("2-01-2020", 1140),
        ("3-01-2020", 1050),
        ("4-01-2020", 934),
        ("5-01-2020", 834),
        ("6-01-2020", 734),
    ]

    labels = [row[0] for row in data]
    values = [row[1] for row in data]

    return render_template("graph.html", labels=labels, values=values)

[wet dust]

dropdowns ig? not sure

[silver tinsel]

and i have everythin the same as in the tutorial and now i have no idea why i get the error :/

would be awesome if someone could take a look at it🙈

[jade lark]

Right, that will happen because the modal is shown by JS itself. What you'll need to do is submit the form via JS with fetch() or axios and then update the form showing the errors with JS as well.

[wet dust]

dropdowns are basically like choose from a list

like it's a dropdown with January, February, etc.

[wet dust]

Not sure tb

tbh*

well if they type something invalid you'll need to check for it

I'd suggest drop downs

for the months

[jade lark]

Are you running the server? Because right now it doesn't seem like you are off the code provided.

[wet dust]

as for the year and day -- just use a regular string field

Well I haven't worked with dropdowns but with string fields

[silver tinsel]

mh what do you mean?

i do that

[jade lark]

Post the code please. For the JS and the html of the form.

[jade lark]

When requesting the page does the console show you an error of what happened? If not you need to turn on debug mode.

[silver tinsel]

.

thats all it shows

[jade lark]

That's not debug mode

and your console for python

[silver tinsel]

thats what the python console shows

[jade lark]

So the template wasnt found

[silver tinsel]

yup

[jade lark]

Theres your problem then

[silver tinsel]

and how do i solve this🙈🙈

[jade lark]

Fix the path

[silver tinsel]

i am pretty sure the path is correct

or which path do you mean

[jade lark]

https://stackoverflow.com/questions/33396064/flask-template-not-found

[inland oak]

is it in folder 'templates'?

[inland oak]

if not, it is probably in the wrong path

[jade lark]

It's not due to the script tag man

it's due to the location of the html file

[native tide]

https://paste.pythondiscord.com/vowomowuxi.xml this is the html of the modal and the js i found

[languid raptor]

@jade lark Just for completeness on this subject. Django-Tagulous says you have to override the models to add their tags. https://radiac.net/projects/django-tagulous/documentation/usage/ I read issues in the django wiki issues which say Django-Wiki has a Plugin system (https://github.com/django-wiki/django-wiki/issues/585). Others have asked about this before (https://github.com/django-wiki/django-wiki/issues/385) but the discussion is hard to follow. ..... Thank you for your take.

[jade lark]

Did you rename any of the ids? Because that should be working.

[native tide]

yeah i added ids for the javascript

[silver tinsel]

Ah yea mb

but as they are in the same directoy the pathing should be correct like this or not?🙈

[native tide]

the submitbutton doesnt do anything with the event.preventDefault(); in the script

[jade lark]

That's 100% right you would want to override the article model. There again, you would use inheritance and either extend or override the model.

[jade lark]

That's the point of it being there.

[jade lark]

No flask looks in the templates/ directory.
If you follow this here: https://stackoverflow.com/questions/33396064/flask-template-not-found
It will work for you.

[native tide]

yeah, but the rest of the javascript also doesnt do anything when i click on the button

[silver tinsel]

so i have to put graph.html in the templates directory

ah well one error is gone now xD

[jade lark]

If you added or changed the ID's that would be why. You want to make sure they're matching with the JS. You can inspect the network tab in your browsers developer tools and make sure the request is sending.

[silver tinsel]

but now i get this :7

[silver tinsel]

ah thanks 👍

[short ingot]

whats the difference between the Premium Intel with NVMe SSD NEW and Regular Intel with SSD in the digital ocean server plans?

[jade lark]

Couldn't find the element. Try moving the script tags to the bottom of the HTML file (if they're not already there). Right before </body>

[jade lark]

My guess without looking at the specs would be IO speed (read/write)

[silver tinsel]

oh damn i am dumb i misspelled it damn

[jade lark]

Happens to the best of us man

[silver tinsel]

ahh now it works 🙂 thanks for your time✌️

[wet dust]

hm I don't see a 'templates' directory

nvm

u fixed it

[silver tinsel]

i fixed it yea 😄

thanks tho

[native tide]

the form isnt sending any request in the network tab and i checked the ids and they were also matching

[short ingot]

so do you think its worth it?

thats the difference

[jade lark]

Depends on your application, probably not tbh due to the way providers like digitalocean work.

Unless you're going with dedicated.

[short ingot]

this is a VPS

[inland oak]

if just for developing

[jade lark]

That's a droplet lad

[inland oak]

any SSD is enough

is it your just testing ground, right?

[jade lark]

so it's a VPS yes, but it's not dedicated

[short ingot]

its my hobby project

[jade lark]

go with the normal droplet then

[inland oak]

more than enough having the cheapest

[short ingot]

ok cool thanks

[inland oak]

I rent for 3,5$ the same thing

[short ingot]

where do you do that?

[inland oak]

as long as it is SSD, and 25gb and 1 ram

it is good

[jade lark]

Without seeing your code specifically I cannot tell.

[short ingot]

also is that 3.5$?

[inland oak]

yeah, it is in my native country, I think it does not exist in English

[short ingot]

ohh

[native tide]

i could show you the whole html file and js: https://paste.pythondiscord.com/tituyezale.xml

[inland oak]

I actually was able to find for same price in English before

but they asked from me

to pay for 1 year in advance%

not really good I thought

[languid raptor]

Does anyone have any recommendations for tutorials or authors who describe/explain Django override of views and models?

[inland oak]

I learned it from official documentation I think

in their tutorial

https://docs.djangoproject.com/en/3.2/intro/tutorial07/

at the end of the chapter

it explains about templates

but I guess everything else should be sort of same

or may be you are looking just for override through inheritance perhaps

[jade lark]

Couple of things:

1. Remove the action from the form
2. Specify ID's for all values of your input fields, that and names
3. You can try specifying a submit event instead of the click event for a button and try that instead

[languid raptor]

@inland oak I will look at that. I've just been looking at Django docs for reference and didn't get into the tutorial. I completed william vincent's override tutorial for admin. I hoped to find more on the web but its tough search

[opaque rivet]

Do you guys understand CSRF and the role of the csrftoken cookie?

[inland oak]

then highly likely you already learned that

[languid raptor]

@inland oak just trying to grokk it better

from 10,000 feet

[languid raptor]

don't you just add the csrf token for forms and it does it's business?

[opaque rivet]

well - yeah. I plan on adding it for my JS forms but I'm a bit hazy on its implementation. Gonna give it an extra read tonight.

doing stuff for the sake of it, without actually understanding what I'm doing, just hurts me in the long-run

[languid raptor]

Well you know. pick you battles. The csrf token is in HTML form in templates. I've not read any particulars which describe edge cases yet. good luck

[native tide]

thanks! the button is doing something now, but it still doesnt keep the modal open

[void spade]

Hey so im trying to get some test done on my django rest framework and it doesnt seem to work on some of my tests

        self.assertEqual(response.status_code, status.HTTP_200_OK)

class CreationTestCase(APITestCase):

    def test_creation(self):
        data = {"name": "test name", "email": "[e-mail]", "phone_number": "+00000000000"}
        response = self.client.post("/api/contacts/", data)
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)

class UpdationTestCase(APITestCase):

    def test_updation(self):
        data = {"name": "test name", "email": "[e-mail]", "phone_number": "+00000000000"}
        response = self.client.patch("/api/contacts/1/", data)
        self.assertEqual(response.status_code, status.HTTP_200_OK)

class DeletionTestCase(APITestCase):

    def test_deletion(self):
        response = self.client.delete("/api/contacts/1/")
        self.assertEqual(response.status_code, status.HTTP_204_NO_CONTENT)

CreationTestCase and GatherTestCase pass

UpdationTestCase and DeletionTestCase get a 404

Im not sure why they are not working when in my postman it does

[opaque rivet]

when having nginx serve your compiled staticfiles (html/js bundles), is nginx technically acting as a cdn?

also can you use redis to cache pages with django? what's the use-case of caching pages? I don't understand the basics of it.

[short ingot]

whats should I use on my VPS Ngnix or Apache?

Im trying to deploy a flask machine learning applications

[native tide]

I have a problem with React Router

here is my App.jsx

https://pastebin.com/tekq1wJQ

The problem is that I don't see the content

In the Switch element

the Dashboard component is not being rendered

also... the Link components are in a different component

in the Navbar.jsx = https://pastebin.com/2FTaTx06

There are no errors in the console

It's just that I can't see the rendered component when I navigate to path='/'

[thorn igloo]

reorder the / path route to be last

or add an exact attribute, if i remember correctly

[native tide]

yow it still doesn't work

[thorn igloo]

can i see the updated code?

[native tide]

I updated this part jsx <Switch> <Route path="/create-loan"> <CreateLoan></CreateLoan> </Route> <Route path="/" render={(props) => { <Dashboard {...props} getTotalMoneyOfStatus={this.getTotalMoneyOfStatus} getTotalMoneyOfStatus={this.getTotalMoneyOfStatus} users={users} loans={users} />; }} ></Route> </Switch>

[thorn igloo]

give it the exact attribute

[native tide]

like this?jsx <Switch> <Route path="/create-loan"> <CreateLoan></CreateLoan> </Route> <Route exact="/" render={(props) => { <Dashboard {...props} getTotalMoneyOfStatus={this.getTotalMoneyOfStatus} getTotalMoneyOfStatus={this.getTotalMoneyOfStatus} users={users} loans={users} />; }} ></Route> </Switch>

[thorn igloo]

no

[native tide]

doesn't work

ok

the top one?

[thorn igloo]

see this example

[native tide]

I did thisjsx <Switch> <Route exact="/create-loan"> <CreateLoan></CreateLoan> </Route> <Route exact="/" render={(props) => { <Dashboard {...props} getTotalMoneyOfStatus={this.getTotalMoneyOfStatus} getTotalMoneyOfStatus={this.getTotalMoneyOfStatus} users={users} loans={users} />; }} ></Route> </Switch> I can see that the CreateLoan component is rendered.

[native tide]

okay

Dashboard doesn't get rendered

[thorn igloo]

ok, i see you are using a render function, what does that do exactly?

[native tide]

I need to use that render function so I can pass props to that component

[thorn igloo]

can't you pass props normally?

[native tide]

No

[thorn igloo]

bruh

what kind of props are you passing?

cause this worked for me

[native tide]

There is a bigger problem I think

The Dashboard components doesn't want to get rendered

<Switch>
                  <Route exact="/create-loan">
                    <CreateLoan></CreateLoan>
                  </Route>
                  <Route exact path="/d">
                    <Dashboard></Dashboard>
                  </Route>
                </Switch>```

I even removed the props and stuff

[thorn igloo]

hmm, i'm not sure what could be the issue. could be some error in the component

[native tide]

Ok now i

[thorn igloo]

try it with another component that works and see if the issue still persists

[native tide]

Ok now Im gonna looks stupid lol

<Switch>
                  <Route path="/create-loan">
                    <CreateLoan></CreateLoan>
                  </Route>
                  <Route exact path="/d">
                    <Dashboard
                      getTotalMoneyOfStatus={this.getTotalMoneyOfStatus}
                      getTotalLoansOfStatus={this.getTotalLoansOfStatus}
                      users={users}
                      loans={users}
                    ></Dashboard>
                  </Route>
                </Switch>``` This works

Now I have another problem

[native tide]

Can python do web frontend?

[calm plume]

@native tide Here's my essay on that

[swift wing]

I ask myself the same question

[random lava]

Hi, anyone know why my json looks weird on javascript?

var test = "{{ testjson }}";
console.log(test)

output

[{'time': 1620588041, 'open': 26, 'high': 26, 'low': 26, 'close': 26}]

json file

[{'time': 1620588041, 'open': 26, 'high': 26, 'low': 26, 'close': 26}]

[calm plume]

Why do you have brackets [] around the json?

[random lava]

all good. i fixed it using | tojson

[errant storm]

Hello,
Is it possible to send a post request from the client side, receive a get request, then change a html element content without refreshing the page? something like this:

on keyboard input event listener -> client sends post request to server -> server sends back a request -> client side receives the request -> element content changed

I'm using flask as backend

[outer apex]

@errant storm absolutely! There's the .text() method while using the Fetch API. You could then insert that html into the DOM.
https://gomakethings.com/getting-html-with-fetch-in-vanilla-js/

[errant storm]

thanks!

[stable hemlock]

Static yes, dynamic is limited without Javascript.

[calm plume]

No

You use HTML/CSS for frontend

Not Python

[stable hemlock]

Fair point.

[vestal hound]

there are ways but they’re not very mature

[errant storm]

async function fetchTitle(e) {
    fetch(`/post/search/title?q=${e.target.value}`).then(
        function (response) {
            return response.json();
        }
    ).then(
        function (json) {
            ele.innerHTML = json.title;
        }
    )
}

Why is ele's innerHTML [object Object]

nvm i accidentally return a json in a json, my bad

[hollow cave]

In django can I just log everything including TLS issues? Because.. I think I’m prevented doing this when the URI variable is only passable as a string when i would expect to pass multiple fields so it’s compatible with ldap.initialise() as I’m wanting to enable trace_level=2

[orchid cove]

which framework is the best for python web dev?

[errant storm]

Flask is easier than Django, Django provides lots of common feature which makes development faster. I'm not sure which one is better, but i prefer using Flask

[orchid cove]

hmm might start out with flask then, I have used falcon before and it came pretty good to me after a while

[worldly furnace]

how do you install flask

is it a program?

[sinful coral]

I'm having a lot of fun with Django + Wagtail.

[worldly furnace]

I just dont understand what the hell Django is, is it a program you install to write front end code?

I'm so lost

[sinful coral]

Python packages aren't technically "programs" in the official computer science sense.

They're scripts that make the Python program do things.

[errant storm]

Django is for back end, for front end u use html, css and website js

[worldly furnace]

So you need to learn Flask code to use Python code to link HTML with python code

[errant storm]

^^

[sinful coral]

No, Flask is Python.

You learn Flask abstractions and write Python to tell it what to do.

[worldly furnace]

It's a version of python code that helps interact with HTML?

[orchid cove]

@errant storm what anime is your pfp from?

[errant storm]

yuru camp

[orchid cove]

tanx

[worldly furnace]

Sorry i'm coming from simple PHP and HTML coding.

This seems so much more in depth

[errant storm]

you mean the {{ }} thing?

[worldly furnace]

But i want to learn it just getting a bit discouraged

[errant storm]

it's jinja

[sinful coral]

@worldly furnace No. The versions of Python are 2.6, 3.9, etc. Flask is just a library written in Python.

[worldly furnace]

So its a library of functions

[sinful coral]

Yes.

[orchid cove]

oh yeah I've seen jinja used before with it, that's some funky syntax lol

[worldly furnace]

That interacts within python code.

So for instance if i wanted to post HTML code within PHP code i would have to "
echo" the code. Something similar to that?

[sinful coral]

When Python runs a Flask app, it generates a web server on your computer that listens for HTTP requests and responds with dynamic HTML generated by your app.

PHP functions a little differently.

[worldly furnace]

I'm currently learning python using the app mimo.

Just for the simplicities of the programming language

[sinful coral]

HTML isn't anything more than a string.

[worldly furnace]

So you just put HTML in the strings within the pythoh

Print('<button>Button</button')

[calm plume]

HTML is a markup language, nothing more, nothing less

[sinful coral]

There is often a templating engine included, but yes, that is the essence.

[native tide]

Kind of like this for a snippet:

<!DOCTYPE html>
<html>
    <head>
        <link rel="shortcut icon" href="{{ url_for('static', filename='images/idrop.png') }}">
        <title>
            Main Menu
        </title>
        <style>
            table {
                font-family: arial, sans-serif;
                border-collapse: collapse;
                width: 30%;
            }

The {{}} is the magic

[sinful coral]

Jinja and Handlebars are examples of templating engines.

[worldly furnace]

that just pulls variables and such from python and implements inside HTMl

Okay so another problem im having is i followed the instructions to do the path for python, and after i created the variable for python i went to system variables to edit the path and the python link isnt in there

[native tide]

So add the directory where it exists and == done

[worldly furnace]

so just add the same directory there

this girl on youtube is talking about adding %% before and after

[native tide]

If you want to rely on windows system variables sure

%system32% etc blah...

[worldly furnace]

when i type in command prompt says python isnt installed, but it is.

[native tide]

Sure, it doesnt know the path

do this, type out the full path of python.exe and hit enter, if it works, then remove python.exe and copy pasta to path

[worldly furnace]

says 'is not recognized as an interanal or external command, operable program or batch file

[native tide]

Whats the path?

My guess is it has a space

[worldly furnace]

C:\Users\emjay\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.9

i dont think i selected add path when i installed

let me uninstall and reinstall with that option seleceted

[native tide]

Yep, no space

Start menu

and Python 3.9

So, you need a quote

"C:\Users\emjay\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.9\python.exe"

^ That would run if its python.exe being ran

I love me some lack of quotes with windows for good ole red team fun...

[worldly furnace]

so i add that as a path under environmental variable?

[native tide]

No

Run that, quoted on your command prompt. Verify python appears

[worldly furnace]

ok

[native tide]

If so, then simply copy:
C:\Users\emjay\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Python 3.9

And place in path. Notice I did not quote

Path knows about spaces, etc.

[worldly furnace]

nope.

can i share screen?

[native tide]

You can paste?

windows key + shift + s

native screenshot if youve win ten

[worldly furnace]

okay i typed version and it came up

So its installed.

[native tide]

So thats the dir, copy it to path and bob is your uncle

[dusk portal]

hey!

[worldly furnace]

This is going to be fun

Definitely so different than what im used to

So I'm creating a webview app using pywebview, where my backend is in flask and the frontend is in a JS framework (Vue). I was wondering what the best practice was for picking ports and syncing them across the frontend and backend. Is there some nice way to do it or do I just have to rely on randomly picking a port and hardcoding it into both, and hope the users don't have something running on it already?

yeh i have just started django

can i get some suggestions to complete it fast and how to do that full plan anyone exp. in django ??

[wooden ruin]

you can't "complete" django, it's a framework. i highly suggest taking a course like cs50's intro to web programming which delves into django

[dusk portal]

how vast is django

and how should i learn it i mean the correct way

[wooden ruin]

django has a lot of features that come included as opposed to a lighter framework such as Flask or Express. like i said, I suggest taking a course or walking your way through things - routers, templates, views, models, requests, etc.

[dusk portal]

i have good exp of flask

is django harder then flask??

[wooden ruin]

it depends. some may say it's easier, some may say it's harder. i think it's harder than flask because it's a heavier framework and might come with having to learn more concepts

[native tide]

^

[dusk portal]

ok im ready to start

[wooden ruin]

great!

[dusk portal]

hmm i always face this issue

i fix it but again face it

 python manage.py runserver
C:\essentials\python\python.exe: can't open file 'C:\Users\91834\manage.py': [Errno 2] No such file or directory```

@wooden ruin

[wooden ruin]

the manage.py file you are trying to run is not in your active directory

[dusk portal]

[wooden ruin]

type dir into your terminal

you should see manage.py

[dusk portal]

05-2021 21:47 <DIR> .
09-05-2021 21:47 <DIR> ..
10-05-2021 11:29 <DIR> .idea
09-05-2021 22:22 <DIR> mysite

[wooden ruin]

[dusk portal]

hello guys..
Need help on Generating Access Code using Django

[proud lintel]

Hi, I was trying to use django with celery and redis , redis server is password protected, so how can i pass my password to redis . I am receiving this error Cannot connect to redis://localhost:6379//: Authentication required
which seems reasonable because I am not passing password . I have tried CELERY_BROKER_URL = "redis://:mysecurepasword@localhost:6379"
but this also doesn't seem working.

[proud lintel]

Using Graphql or rest?
