Hey guys i have to make a api at work. Where i have to connect to a mongodb database. It should take JSON as request like {"status" : "panding"} and api should respond data from mongo where Status is pending. How do i do it .? What should i use ?

dry obsidian
#

So first of all I have an idea for a website. Lets say you are a content creator and you want to find a clip where youtuber 'A' says something like "Hello everyone", "Bye"...
To do this my app would need to first gather all the youtube videos of a channel. Then it would need to get the subtitles of every single video. That would require a lot of API calls, let's say like 500. What would be the fastest way to do this?

dry obsidian
#

Or can a client make all these API calls fast enough

Where can I practice CSS on artificial tasks?

#

Or rather, apply CSS so that the page doesn't look like crap.

calm plume
#

I often go to a random page, go to Firefox's "Style Editor" in dev tools and mess around.

That doesnt change anything im afraid

#

Well especially on the breaking TOS side of stuff

dry obsidian
quick cargo
#

You can download the captions

#

It's the video side of it thats the issue

#

You cant do that via the api

In that case is should be okay

Hello. I'm trying to make spanish dictionary but I don't know how to make database. Does anyone have an any idea how I can do this?

main grail
#

I dont know too

warm igloo
#

I mean, we can't teach you via chat but there are lots of tutorials and such out there.

#

To start, look up how to use python and sqlite together. That'll be the lowest barrier to working with a db.

native tide
#

where can i find a database online for free?

calm plume
#

Or are you looking for a database that you can use to store your own data?

native tide
#

yeah i wana store data ther

#

there

#

its not that serious tho i just wana test a project

#

like i dont care about security or anything

calm plume
#

Postgresql, mysql, mssql, etc.

native tide
#

yeah i know them all

#

the thing is

#

how can i use it online

#

like how can i save the data online

#

not on my pc

#

is there a way to do it for free?

#

even for just a couple of rows or smth

Could someone please suggest a decently built flask project I could look at that follows a structure similar to the following:

#

I already have this question in #help-mango but wanted to ask short version here does flask not render anything that is in {{variable}} in template?

inland oak
#

The {{ variable }} thing is rendered, it is expected you will pass it into template

rough garnet
#

Nevermind as stated #help-mango I found solution by a bit of googling

#

using {%raw%} solves problem

#

Let me better frame my question, how to make flask to ignore all {{}} because I am using those for vue js templates

inland oak
#

Percentage symbol is used for loops and other stuff

inland oak
#

Disable jinja2 usage

rough garnet
#

No I actually need to pass few lists to javascript

#

I found using {%raw%} tells flask to treat underlying text as raw text

#

That solves my problem

inland oak
#

This is wrong solution involving dirty hacks

rough garnet
#

I mean it is working yert

inland oak
#

So not use Jinja 2 at all, since u a already with frontend framework

rough garnet
#

I have not actually get decided Everything thing but yes lists should be fetched from an api my current implementation is very dirty

Hey there, I am working on a project where I am using React as my frontend and Django as my backend. However, I am stuck at the part of authentication users, are sessions still valid in react ? Since if I am not wrong react will mostly interact with the backend with some sort of API. If sessions aren't the way to go, is there any other simplified explanation for authentication?

I think you may need to wrap {{ form.role_field }} in an <option></option tag

How can I link an external css file to an html file? I followed what the Django documentation is saying, but it doesn’t seem to get applied

Hey, @vernal lotus I think next thing is looking at the docs it says that choices needs to be a tuple of tuples, and you're passing a list of tuples. Maybe try that change next.

Quick question. I'm going through Corey Schafer's Flask tutorial, and in video 2 he's making a template for each route in his main .py file. My question; is a separate template needed for each route/page, or can a given template be used for multiple routes/pages if necessary/convenient?

In this Python Flask Tutorial, we will be learning how to use templates. Templates allow us to reuse sections of code over multiple routes and are great for serving up dynamic HTML pages. Let's get started...

probably just extra in your template

vernal lotus
# 
<div class="mb-4">
 <label class="my-1 me-2" for="role">Role</label>
 <select class="form-select" id="role" aria-label="Default select example">
 <option value=""{{form.role_field}}""> </option>
</select>
</div>
warm igloo
#

yeah, you have double "

#

the first set self-closes

vernal lotus
calm plume
#

<option value=""{{form.role_field}}""> </option> should be <option value="{{form.role_field}}"> </option>

warm igloo
#

get rid of the extra around {{}}

vernal lotus
warm igloo
#

and now?

vernal lotus
warm igloo
#

can you post code somewhere more convenient than screenshots?

#

pastebin, repl.it, something like that

#

can you show the code you have now for the field then

vernal lotus
#

okay wait

# 
<div class="mb-4">
    <label class="my-1 me-2" for="role">Role</label>
    <select class="form-select" id="role" aria-label="Default select example">
    <option value="{{form.role_field}}"> </option>
    </select>
</div>
warm igloo
#

and you still see extra characters?

vernal lotus
#

yes

warm igloo
#

inspect the drop down and see .. something in your choices value might be ending the string early with an extraneous "

#

even better than inspect, which the browser will attempt to correct, choose "view source" instead to see the raw output

#

also, I think "role_field" here is outputting the WHOLE select .. you shouldn't need to be so manual with your template

#

so my guess is role_field has a bunch of html in it you don't expect

vernal lotus
#

okay bro i'll investigate the extra characters.

            raw_password = form.cleaned_data.get("password1")
            user = authenticate(username=username, password=raw_password)
            
        else:
            data['form_is_valid'] = False

    context = {'form': form}
    data['html_form'] = render_to_string(template_name, context, request=request)
    return JsonResponse(data)

I've another quick question. In Corey Schafer's Flask tutorial (https://www.youtube.com/watch?v=QnDWIZuWYW0), he's set up a main flaskblog.py file with routes inside it that utilize an unique html file as a page template for that specific route (for example; the "about" page's about.html). Each individual route's html file contains extension code {% extends "layout.html" %} that references layout.html, which is where the bulk of the page's html code that builds the pages of the website (I can see why; one main template keeps code DRY and minimize the effort necessary to make changes). I'd like to make sure I understand this: flaskblog.py is going to use route code to access about.html, which extends layout.html, and build a page that's mostly code from layout.html, with an extension from about.html? That 3-step pathway; flaskblog.py--> about.html --> layout.html is the path the computer uses to build the page?

U need to initialize your db again, migrating command will do it, and then to create super user again

Saving test/dev db is a really bad taste. Better to init from zero/config/whatever

hey guys, in flask, if you're using flask_sqlalchemy. How can you store the filtered user class in the session like django.

i have this view

@auth.route('/login', methods=['POST','GET'])

    if request.method == 'POST':
        form = LoginForm()
        if form.validate_on_submit():

            if not user:

            else:
                user.is_active = True
                login_user(user)
                return redirect(f'/{user.username}/home')
    else:
        return render_template('login.html', form=LoginForm())

how can i do this

@auth.route('/user')
def userQuery():
    return str(user.email)

just seamlessly add the user into the session. do i need to use cookies or somthing and access those? or is there a actual add to session function thats safe

Hey @buoyant geode!

Uh-oh! It looks like your message got zapped by our spam filter. We currently don't allow .txt attachments, so here are some tips to help you travel safely:

• If you attempted to send a message longer than 2000 characters, try shortening your message to fit within the character limit or use a pasting service (see below)

• If you tried to show someone your code, you can use codeblocks
(run !code-blocks in #bot-commands for more information) or use a pasting service like:

'user-posts' is not a valid view function or pattern name

where did you write user-posts

#

carefully check and make sure you spell it correctly

#

so that it matches with the url or view that you created

also why are you using django

because your HTML does not have no div

what is server side rendering? Generate pieces of html and send to front-end which requests them using js or something? Hybrid SSR SSG?

royal quail

Thank for all your help @muted scaffold and @past cipher

tardy heron
#

which is better? Gatsby or Next.js? 😄

#

i would ask about python, but it doesn't work in browser. Idk where I should start with react, and what kind of a toolchain i should pick. I'd rather get it right, since assumably it's a pain to change it afterwards?

SSR -> do this on the backend

#

so, basically

so SSG = javascript generating html. SSR = jinja 😄

you have to py await self(result) not the other way around also Only asynchronous (defined with async def) functions can be awaited. Whole idea is that such functions are written special way what makes possible to run (await)

Hey, in which cases is python better for web dev then lets say javascript?

meager anchor
#

it's hard to make a claim about the whole python language compared to the whole javascript language. it depends on what you want to build, which web framework you want to use, etc.

woeful remnant
#

I mean like there has to be something that really sets python a part from the whole node.js/react.js stack when it come to WEB DEV

meager anchor
#

for me there are plenty advantages but it's mainly related to the language itself (exceptions for type problems, ecosystem ...) and the django framework being a brilliant choice, but there's no real advantage of one language over the other for the entire web dev stack, apart from perhaps javascript working in frontend and backend so you need to learn one language less

woeful remnant
#

Yeah well that was my point, it seems like its all too good to be true with JavaScript, so why would anyone or any company choose to build with python and javascript when they could just go full on JS

#

that was my initial dilemma anyway since I am a beginner its a bit confusing you know

#

When it comes to choices like that I can't reason correctly - since I am new to coding in general

indigo kettle
#

you're in a python discord so people will probably be partial to python/django/flask here. I like these things too but I think going full js makes a lot of sense

#

That being said, I've never used node in the backend and work full time as a web dev using django

woeful remnant
#

There is no chance in hell I will leave python for JS, I am only asking this kinds of questions to know upfront how to manage my career in the future because I plan to only work with python, i tried JS and it is not good for me (i don't wanna use stronger language)
the only thing i like is python so I am like now eliminating all options that will get me to mandatorily learn other languages
maybe its not a good approach and narrow sighted but hey thats me I like what I like and its python and I don't like what I don't like and that is other languages... 😛

indigo kettle
#

Once you get more comfortable with python you may find yourself less averse to learning a new language. And it will be pretty hard to get into web development without getting familiar with javascript

#

Trying to learn many languages as a beginner would be pretty hard though, I think.

woeful remnant
#

Yeah I get it, but I have a clear and very precise goal set for me
and that is to learn as much python as possible and to get paid $2.300 a month remote job and thats it, there is no javascript for me, no need, Im not after 100k/year jobs or buiding my webb aps or react native mobile apps etc.. im a simple person 😄

dusty moon
#

Cool

#

So, wait… basically I can use Python with html css?

inland oak
dusty moon
#

Cool

#

Should I though?

inland oak
#

You can use Python(Jinja2) with Html+CSS + with limited simpliest javascript

#

as a more enterprise solution....

#

Python is used as a REST API that returns JSON data

#

and for frontend u use proper frontend framework with HTML+CSS+Cool javascript level

#

and just fetch data from your python frameworks with requests for json data

dusty moon
#

Oh.

#

So only APIs? I can’t do simple stuff like make an html button do stuff?

inland oak
dusty moon
#

I’m talking about functionality

inland oak
#

for simple solutions python framework would be enough

dusty moon
#

Ok.

inland oak
#

frontend framework is wished when you use javascript extensively

#

it is just better way to use javascript

dusty moon
#

Btw, just a random question: are there any Python UI libraries that I can design stuff using CSS?

#

I heard PyQt can do that, but I’m not sure…

not knowing, I am going only to start using desktop stuff soon

Hi, I'm using Django and have a social media platform where there are posts by users

Users can react to posts, every time there's a reaction I send a notification out

#

If the post is liked once
example: A liked your post

#

I don't want to send a notification again if A decides to unlike and like it or A unlikes it and someone else likes it

#

Do I store an extra field in the model as first_notification - boolean?

how do webservers handle multiple requests at the same time? do they have multiple instances of the same program?

#

well. they talk to the socket. so you have to use somethign like uwsgi, gunicorn etc

torn junco

modern edge
native tide
#

ye can take a long time to understand

#

read about wsgi and asgi

#

and set one up

torn junco
native tide
modern edge
native tide
#

i.e. point nginx and it and run your flask app with it or something

#

you will lose a few weekends and a lot of hair

#

think of it as php-fpm

#

or will it hog up the memory lol

modern edge
#

nah dw i will look into it

torn junco

#

its that easy in a way. but ramps up. i.e. you have to pass logs through it

how does it know when to kill the child process

you kill it

#

wat

torn junco

ye there's even settings for that

the config can get big.

#

there's weird names for params

#

voodoo stuff

#

doesnt Flask handle all that

#

na uwsgi. id stick with that. its easy. there's others. gunicorn.. lots i think

#

plus asgi is coming in now due to async

#

but uwsgi is a good place to start

torn junco
modern edge
#

ah

#

well

#

shit

#

lol

torn junco
#

sorry

native tide
#

ye. it's like that at first. then you know

modern edge
#

no no its not your mistake

native tide
#

and you have to help others

modern edge
#

thats how u learn ig

native tide
#

so really you will start with this

#

but it will get long with lots of params

#

so you will need the config file

#

myapp.ini

#

and just pass it the config

#

then you have a service which starts it on boot

#

so you can just kill that service if you want. or restart it. like you would nginx

#

then in nginx. you create a reverse proxy. and point it to the socket that uwsgi makes

#

there's lots of tutorials online

modern edge
native tide
#

to start. find a good tutorial and copy and paste.

#

do that for about a year each time you need to run an app. and some bits will start to fall into place

modern edge
#

well currently i just want to know what happens in the backend of backend and to know if Flask handles all that

native tide
#

is flask async yet?. try sanic

how can it not be concurrent

every web app should be concurrent

no?

you tried sanic?

if (clicks >= requiredclicks){
document.querySelector("#levelupbtn").style.visibility = "true";
}
else{
document.querySelector("#levelupbtn").style.visibility = "false";
}

you mean once u close the program u want it to still be running?

orchid olive
#

there is an internal clock that stop a webpage to continue working and send you to login again, i need to increase that time to 1 or 2 hours instead 15 minutes

#

could be session time but i am not sure

outer apex
#

Can you expand on "continue working"?
My understanding right now is a user logs in, 15 minutes later they refresh the page and is logged out. You don't want them logged out after this 15 minutes.

Somewhere in that code you're setting NaN to the progress' max and/or value. NaN is not a finite value. You might want to check whether you're actually setting a Number!

Never used it but your syntax does look correct. And that's right before the function that is being called a lot?

You don't want to decorate a function that itself is going and making a bunch of calls, that won't do anyting.

This will only rate limit your function from being called too frequently.

So in your logic, make sure the function to do the fetching against the API is the one decorated. This won't work around a function that itself is the thing setting up a loop to do calls as fast as it can.

Understand what I mean?

wraith prawn
#

gotcha

#

i think ive figured it out

warm igloo
#

cool

wraith prawn
#

within my function, the calls were doing during a loop

#

as I was decorating the function, it wasnt applying to the calls within the loop

warm igloo
#

ah yeah, you want to move whats in that loop to a func itself and ratelimit THAT

wraith prawn
# 
from ratelimiter import RateLimiter

rate_limiter = RateLimiter(max_calls=10, period=1)

for i in range(100):
    with rate_limiter:
        do_something()```
warm igloo
#

ah yes, with the context managert

wraith prawn
#

this is what I had to do, and what worked

warm igloo
#

great

wraith prawn
#

🙂 thanks for getting back to me though!

warm igloo
#

you could also decorate do_something()

#

at its def

#

you're welcome! glad you figured it out

wraith prawn
#

thats sample code, mine isnt a def within the loop

#

just code

warm igloo
#

#

best of luck on rest of your project though

thanks!

# brave jolt from . import views (what does the . mean here)

Relative import, from where your project is running.

"The dot (.) symbol after in an import statement of the form from . import your_module is a Python syntactical element for relative imports. It means “look for the module in your current folder”. The current folder is the one where the code file resides from which you run this import statement."

short story: no

#

the longer story: yesn't kinda,....
python simply is not as performant as some other languages, this is due to a lot of reasons but that is not really important here, however what python has is an extremely large ecosystem of libraries to help with web applications, especially apis where the raw performance has a negligible impact on real world performance

#

not to mention the speed of development you get with python compared to languages like cpp or rust

#

there's a good reason why python is used extensively in the backends

#

that said, you probably dont want to use python to serve static files

tepid lark
#

plus. most web apps aren't especially cpu bound

#

and if they are, you can usually offload that stuff to something more performant

Hi, I'm trying to implement hashtags in my django app

#

I have a message model with a field like this

#

And this is the HashTag model

    hash_tag = models.CharField(max_length=140, primary_key=True)
#

And I'm setting the hashtags to the message like this

            hash_tags_list = Functions.extract_hashtags(message["message"])
            hash_tags = [HashTag.objects.get_or_create(hash_tag=ht) for ht in hash_tags_list]
            messageObj.hash_tags.set(hash_tags)
            messageObj.save()
#

But this errors out

django.db.utils.IntegrityError: insert or update on table "messaging_message_hash_tags" violates foreign key constraint "messaging_message_ha_hashtag_id_068959e9_fk_messaging"
DETAIL:  Key (hashtag_id)=((<HashTag: HashTag object (skills)>, True)) is not present in table "messaging_hashtag".

    artist = models.CharField(max_length=100)

class Track(models.Model):

    order = models.IntegerField()
    title = models.CharField(max_length=100)
    duration = models.IntegerField()

    class Meta:
        unique_together = ['album', 'order']
        ordering = ['order']

    def __str__(self):
        return '%d: %s' % (self.order, self.title)

The view you choose is dependent on what you actions you want to be able to do with the serializer. This is a helpful reference if you haven't come across it before: https://www.cdrf.co/

Django REST Framework 3.12 -- Classy DRF

The best way to understand Django REST Framework class-based views and serializers is to see it in Classy DRF (based on CCBV), so pick your version and jump in at the deep end.

# surreal portal If it's ListAPIView or something else

To add on to this, if it's list or detail view then the serializer should work. However, if you're trying to make a Patch, post or put request, I'd recommend using a different serializers that has all fields without defining serializer method field.

when you execute commands in terminal they are run in a directory called cwd

i know its a character set but i dont understand why

#

or whats its concept

if you leave it your browser tries to figure out the encoding from the response headers and then falls back to a default

#

which I think is usually utf-8

i dont understand what u said right now ;-;

it usually won't change anything whether or not you include it

text is internally a lot of binary

simple garden
#

well what does it do

#

like what does it change

vestal hound
#

an encoding is how to turn that binary into human readable letters

#

hold up let me get an example

simple garden
#

okayy ty btw

vestal hound
#

is 🔥 in ASCII (an older encoding)

#

in binary they are the exact same

#

just a long chunk of 0s and 1s

simple garden
#

yes i get it

#

but dosent it do that automatically

vestal hound
#

most everything uses UTF-8 nowadays

simple garden
#

so what does it change?

vestal hound
#

IF you were to change the encoding manually you’d see something different

#

but for the web it’s mostly a curiosity nowadays

simple garden
#

so pretty much putting meta charset utf8 is like just translating it into normal words

#

thats all

vestal hound
#

a complete answer would go into the history of encodings, but that’s the gist of it

Does Django share any state between requests? I assume it's multi threaded running w/ gunicorn or w/e. Would I run any into issues with different threads accessing the same object from a factory function?

#

do I figure out how to make a thread safe singleton or just eat the cost of recreating an ldap connection for each request

#

the core ldap3 instance appears to be thread-safe when using a certain connection strategy, so I think it's just my wrapper class I'm worried about

then yes

seems like it's mostly mitigable

Hey everyone, I am trying to set up a development environment for building HTML/JS and my goal is to mirror the service I want to upload my HTML/JS code to but they use template rendering variables like
@customer.full name@
and I cant for the life of me figure out how to get this to work on a http server set up with python. The closest I got was Flask & Jinja with a custom variable start and end string but that wont let me put spaces in the variables. Does anyone have any idea how I can accomplish template rendering with spaces in the variable names using a python http server?

I am not the one who put them there, the web application I am using will pass variables into the HTML / JS file and the variables from that application use spaces. I am trying to mimic the environment so I can easily copy my HTML / JS files up to it without having to replace variable names

tepid lark
#

I reread your question, sorry, I get it now. Uh are the spaces consistent?

All I can imagine is tempale your things w/ Jinja and do some custom string interpolation/replacement.

cerulean dock
surreal portal
# 
root@d454b11f26bd:/app# python manage.py makemigrations
No changes detected
#

According to this, it should work?

#

That's probably bc I'm already using an already instanciated db

#

Which is weird

#

Any way to force migrations on the DB?

Hey guys. I'm starting to learn Django. Anyone know of any good resources? I know Python thoroughly, but haven't tried web development in Python yet. In terms of Web Dev, I know the basics (HTML, PHP, JS, etc) so it doesn't have to be totally introductory.

#

Oh there's a resource list under #welcome my bad 😄

Hello,i'm with a problem with my my api in django. So when i try to acess the endpoint i got this error:

unknown.png
#

what i suppose to do, i've checked my serializer and its everything allright with them

#

here my models and serializer

#

serializer

unknown.png
#

and this error appears in all routes

native tide
#

@honest tartan can you show your views.py file

honest tartan
#

sure

native tide
#

And try once

honest tartan
#

line 11 of the views?

native tide
#

Yes

honest tartan
#

ok let me try

#

it worked, but i dont undesteant why this heppended, the many argument its not for a many to many relation?

native tide
#

No see the thing is when you are doing

Class.objects.all()

It is returning a queryset and not a single object , if you had done

Class.objects.get(nome='pikachu')

It would have returned a single object

#

So whenever you are using all() to get data
Make sure to pass many=True in serializer

honest tartan
#

ahhh i see

#

thanks

native tide

I have a notice model that creates s notice (it contains title, description and date). I would like to schedule notices to be created at certain dates. Basically, I mean using another model I want to schedule and create the notices at that date specified.

#

How would I do this? What's the easier road to achieve this? All I can think of is rabbitmq and celery. And i don't even know how it would create s notice at a dynamic date.

Hi im trying to make verification page for my site in quart but i when it comes to verify solution keys i get 2 seprate keys and i dont know how to fix that, my code is:

@app.route("/verification", methods=['GET', 'POST'])
async def verification():

    response = requests.get('https://captchaAPI.pythonanywhere.com/api/img').json()

    random_image = response["url"]
    solution = response["solution"]

    if request.method == 'POST':
        input_sol = (await request.form)["cptc"]

        if input_sol == solution:
            print('Nice')
            print(solution)
            print(input_sol)        
        else:    
            print('Invalid captcha')
            print(solution)
            print(input_sol)


    return await render_template("verify.html", random_image = random_image, solution = solution)```

I am new to web development and Im hoping someone can help explain when is a good time to use asynchronous programming or not?

#

I see async await in a lot of different code bases, but im not entirely sure when you would want to use asynchronous functions.

meager anchor
meager anchor
#

for instance, imagine your web app makes a call to some other app which waits with the response until some job has finished, if you made an asynchronous request there, everything else in your app could keep running

wispy niche
#

ah ok i see. So if my application pings some other api, i would probably want that to be an async function?

no sorry I worded that a bit oddly, it's hard to generalize when you want to use an async way of calling stuff. i can give you one example from my work, i maintain an API which deals with tons of concurrent requests, and that API writes some data it retrieves via the request to two backend databases. now all the calls to the backend databases are asynchronous and while we're waiting on the databases to save away the data the app can continue doing other stuff. before I rewrote it to be async, it was really sluggish since every request had to wait for the backing databases to save it away

zealous smelt
#

oh

#

wait

wispy niche
meager anchor
#

i would guess most newer apps do, yes. but there's also excellent frameworks that aren't completely async, such as django or flask, so it's really a matter of what you want to do

zealous smelt
# meager anchor (assuming you have request session storage set up)

I accualy don't but i found example of cookie session

from quart import session
...


@app.route('/')
async def index():
    return await render_template(
        'index.html',
        colour=session.get('colour', 'black'),
    )

@app.route('/colour/', methods=['POST'])
async def set_colour():
    ...
    session['colour'] = colour
    return redirect(url_for('index'))```
#

I never used sesstions that much

Well, first mistake @amber cobalt - Python 2.7 😆

amber cobalt
#

@glad pendant I know, I know...slap me for this. It's legacy stuff.

#

I'm afraid if I use 3.9, Django and even my codebase will need to be overhauled since many things have changed.

#

I tried: r = requests.post('https://foo.com', data, verify=False) but newer apps are not passing SSL whereas older ones (Java based) are validating

how is my model intaking `files.File(fp))`? so that I may use this picture 
```py
fp = BytesIO()
fp.write(resp.content)
print("name:", i, "files:", files.File(fp), "file:", fp)
u.photo.save(i, files.File(fp))```this is what its printing out for me `files.File(fp)`

name: myfile files: file: <_io.BytesIO object at 0x7flee65b3810>```

#

it does save a file on my server but not accessible for me to open as a image

#

I would have to read that file from my server through BytesIO?

how can I parse the data from a response?
the flask api returns a string (not using jsonify function).
I've tried to use r.dict_ to find anything that might help, but the data seems being wrapped by ClosingIterator
How can I extract the string?
Thanks

Figure it out, I should use ".data"

true kernel

I was making a library app in django, and I configured urls so that localhost:8000 would redirect to localhost:8000/catalog/

#

but now I'm making a new app, and the home link still redirects to /catalog automatically?!!

vestal hound
true kernel
#

like so (in project's urls.py):

from django.views.generic import RedirectView

and then append this line to urlpatterns

path('', RedirectView.as_view(url='catalog/', permanent=True)),
vestal hound
#

so

#

if you’re sure that that’s not in your new project any more

#

could you try this

#

open the website in incognito/private mode and see if you still get redirected?

true kernel
#

ah alright

#

this one says page cant be found

vestal hound
true kernel
#

no?

#

i want my app to run

#

normally

vestal hound
#

do you have a view matching that route?

true kernel
#

like, localhost:8000 should render the home page

true kernel
vestal hound
true kernel
#

Oh and also

#

this things happening on edge

#

but not on brave

#

or chrome

#

on them the apps running fine

vestal hound
#

well

#

then something’s wrong with Edge

true kernel
#

"Maybe you used a "permanent" redirect? Browser can remember those..." I got this from another server

vestal hound
#

that’s why I said use incognito mode

#

so cached responses wouldn’t be used

vestal hound
#

since the same URL is resolving on other browsers

true kernel
#

yeah so in brave's incognito its still running fine

#

idk what to make of that

true kernel
#

on edge I mean

#

can I somehow clear last day's cache in browser?

#

lmaoo I cleared the data and its working now

#

this was trippy

vestal hound
#

yeah in general if stuff from the past lingers

#

try in incognito

#

or ctrl f5

Maybe a stupid question, but how easy is it to implement JavaScript API's such as WebGL / three.js for smooth animations when programming with Django? Should I rather look for a Django specific alternative to do animations?

#

I.e. my question isn't how easy is it to do animation, but rather if it would be acceptable for me to use JS APIs such as three.js and WebGL while developing with Django/Python.

vestal hound
#

how would you do animations with Django

dusky field
#

So my question is basically, can I use Three.js alongside Django? Three.js would handle the animation side of things using JS.

vestal hound
dusky field
#

@vestal hound or are those two things mutually exclusive? I would think that it should be able to put Three.js in the static folder, since it's basically just a JS API? Or am I being stupid

vestal hound
#

they handle fundamentally different things, right

vestal hound
#

but

#

ultimately

#

it's just a JS script

#

that you can use in your HTML templates/files

dusky field
#

awesome

#

cool

thank you!
