[thorn igloo]

oh, you're using wtforms,

[quasi relic]

yes

[thorn igloo]

i've tried to use it to upload, but i never got it to work

[lavish prism]

Hey @quasi relic!

It looks like you tried to attach file type(s) that we do not allow (.html). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a.

Feel free to ask in #community-meta if you think this is a mistake.

[quasi relic]

it seems I cannot send here files yay, ye I tried it

the text

[mint folio]

Anyways what I was going to say was that make sure you have the enctype as multipart/form-data to post files through a form.

[azure saddle]

I am getting the error TypeError: unhashable type: 'dict' and this is my code:

@app.post("/novels")
def add_novel(novel_data: Novel):

    new_novel = {
        "title": novel_data.title,
        "author": novel_data.author,
        "synopsis": novel_data.synopsis,
        "accepted": novel_data.accepted,
    }

    novels_collection.insert_one({new_novel})
    return {"data": new_novel}

When i try to just novels_collection.insert_one({novel_data}) it gives me a similar error TypeError: unhashable type: 'Novel' (this is using fastapi and pymongo)

[quasi relic]

oh ye it worked thanks, so what does it mean, what does it do?

[quick cargo]

{} is being treated like a set, because you already new_novel being a dictionary, so you're just trying to insert a dict into a set which cant be done

[mint folio]

It’s just how you encode data that will be sent, and so allows files like that to be sent.

[quasi relic]

alright thanks so much 🙂

[azure saddle]

oh i see, thanks but how do i make {} not being treated like a set? do i just

novels_collection.insert_one({"novel": new_novel})

? or is there another way? (my brain has a hard time computing today and in general so sorry if this question seems stupid)

[quick cargo]

well, its already a dict

if you want it to litterally have those keys and columns as is in the db

just give it the var

if you want it to be stored like:

{ 
  "novel": {
    # ... Stuff  
  }
}
``` then use the `{"novel": new_novel}`

otherwise

just `new_novel` will produce:

```py
{
  "title": stuff,
  # ... etc...
}```

[toxic plaza]

Hi,
I'm building a content aggregator app which will scrape the data from some websites and present those data (after doing some formatting) to the frontend. I'm looking for some suggestions , references on the python framework etc. to use.

[azure saddle]

oh okay, thanks a lot for your help and time! i really appreciate it

What is the difference between Django socket.io and Django channels?

what to use when?

[peak lava]

is it possible to change the maximum characters required to enter for django.contrib.auth signup password (which is 8)?

[tough snow]

Hey there, I was hoping to get some clarfication. I have been working with Flask for a few months now, and think it is awesome. I love the factory design principle that can be used, and blueprints. Also super excited about Flask 2.0 and the nested blueprints that are now available. I have always created monlithic apllications, and only really got introduced to the concept of Microservices recently. But as I was working through the concept, I was not clear how Micoservices would really be a change from just using Blueprints. Are they pratically doing the same thing? Or there advantages to using various microservices with or without blueprints?

[terse vapor]

uhhh, use the django form i guess?

@buoyant shuttle Are you able to see code now ?

[buoyant shuttle]

Yeah I'm on phone switching to laptop

What's the problem again

[buoyant shuttle]

why are u jsonifying, a 403 forbinned error

403 means u cant access it

[sacred forge]

Can I add def to <button> in flask ?

from flask import Flask, render_template_string

app = Flask(__name__)

def test():
    print("test")

@app.route('/', methods=['GET', 'POST'])
def index():
    return render_template_string('''
    <button>click me</button> 
    ''')

if __name__ == '__main__':
    app.run(debug=True)

How I add function to Button ?

[buoyant shuttle]

403, literally status means u cant access the content in that url

the server is stopping u

The HTTP 403 is a HTTP status code meaning access to the requested resource is forbidden. The server understood the request, but will not fulfill it.

it means the server got your request, but would not give u the ideal content

[elder echo]

Hi guys, I'm kinda new to css

[buoyant shuttle]

thats javascript stuff

[elder echo]

I know the basics, but I was wondering when should I get into bootstrap??

[buoyant shuttle]

you can stry to add a script tag, and run your js there

[buoyant shuttle]

bootstrap is a framework, basically if you dont want to make your own stuff

[elder echo]

Yeah, I'm having a hard time making the websites I kinda pictured in my head

and I tried bootstrap but I didn't understand the "container" classes and all that

[buoyant shuttle]

container is like a box, or someting just a div that expands. you can make it with pure html and css

[sacred forge]

can u send me script ?

for this

[elder echo]

So basically a responsive section of the site?

[buoyant shuttle]

do you know javascript?

[buoyant shuttle]

just as the name suggest

plain container

[sacred forge]

nope

[buoyant shuttle]

i suggest u learn js,

[native tide]

Getting started with flask in pycharm. I'm pretty sure my server is still running in the background after closing pycharm but I can't find what I should kill in the windows task manager... Is this common? Also is there a name for the default "server" back end of flask?

[thorn igloo]

does going to localhost produce anything?

[native tide]

http://127.0.0.1:5000/ returns "index page" (as a test)

[buoyant shuttle]

this could be true

[native tide]

so yeah

[buoyant shuttle]

kill the process running on your server lol

[thorn igloo]

hmm, are you on windows?

[native tide]

killed all python apps so not sure what to kill next

[buoyant shuttle]

also never start server in pycharm use cmd/terminal

[thorn igloo]

if so it's probably a python process

[native tide]

Yep and most google answers are for linux...

[buoyant shuttle]

i mean using cmd commands

[native tide]

Why?

[buoyant shuttle]

it runs on port 5000

[thorn igloo]

right click taskbar > task manager

[buoyant shuttle]

cause u cabn close pycharm and the server is still running lol

https://medium.com/@javatechie/how-to-kill-the-process-currently-using-a-port-on-localhost-in-windows-31ccdea2a3ea

kill port 5000, and it stops the process running on that port

[native tide]

that did the trick, looks like I missed a python to kill, thanks !

so in order to test run a flask project I should run it outside of pycharm? Doesn't pycharm know how to handle flask projects and close it?

[buoyant shuttle]

Im not saying that its bad, but i have that habit that pycharm would do it for me. So i run the server in command line, seperate

[native tide]

alright will keep it in mind 🙂 that background server also explains why I couldn't see the changes when running the script....

[buoyant shuttle]

[vagrant remnant]

As someone who keeps trying to learn Javascript but my own biases against it keep getting in the way, and I already know Python pretty well, is there a recommend tech stack for web development that minimizes the amount of JS I have to write?

[fair agate]

Anyone on with experience integrating PostgreSQL using psycopg2 into base flask for an API? I have some questions regarding best practices for integration, I'm used to SQLAlchemy so I'm eager to try to find cleanliness/DRY shortcuts for the code rather than bloating

[fair agate]

Is there anything wrong with having one handler function and having a series of if statements for method eg if request.method == 'PUT': as an example?

[mint folio]

Yeah it can get bloated, and hard to read or maintain

Each route should be doing a specific thing to a resource.

For your database functions, you might want to have a data layer and this way if you ever do have to change the implementation its easier to do so, without affecting other parts of your code.

[jade lark]

Honestly, the recommended tech stack a lot of the time now involves a frontend that uses JS and a lot of it.

You can get away with using a templating engine. This does depend on the complexity of the project/site.

[fair agate]

How best do I go about doing this? I'm in the midst of figuring it out but I'm not sure how I'd abstract the methods for writing/reading etc from DB without purpose building each function

[jade lark]

Create a crud.py file in the same package. There you can create simple functions to read, update, delete, etc. Also there is absolutely nothing wrong with using if statements to delegate a request based on request methods.

I would recommend not having all of your logic in a route though. If you find you're doing that a lot. Create a utils.py file in the same module and create the logic there. If you find you're repeating something a lot and need the utils used across blueprints, move it out of the "app".

[tulip dock]

Hey, should I go for django or flask for learning web dev & execute my own idea?

It seems as if django has more data, so it would be better to learn

[austere relic]

I've used aiohttp so far

but idk

[jade lark]

That really shouldn't be used unless you have some really specific reason...

[jade lark]

Whats the idea and the requirements of the project, or end goal

[austere relic]

hmmm?

[jade lark]

As a webserver

[austere relic]

yeah. I don't see the problem

[jade lark]

Why would you want to use it for a server?

[cyan lotus]

django doesn't look into the "templates" folder under my app

I've added my app in INSTALLED_APPS and APP_DIRS is set to True

[austere relic]

why wouldn't I?

[jade lark]

You'll have to create everything basically from scratch? 👀

[austere relic]

nah

xd

[jade lark]

I mean you definitely do but to each their own

[austere relic]

for templates there's jinja

[jade lark]

But there also is not much out there based on. This includes packages, tutorials, probably even stuff on stackoverflow. If you run into a big problem you're probably on your own.

[austere relic]

hmmm, that's fair a point

you're right that has been a problem

[jade lark]

I would guess it would be.

If you need an async option there are actual frameworks out there.

[austere relic]

maybe i'll try more stuff
but like it so far
def a lot better than apache + cgi

[quick cargo]

Seems to be some miss-conception of stuff

aiohttp is fine with it's inbuilt webserver

its production ready, e.g. it's the same standard of gunicorn, uvicorn, hypercorn etc...

[jade lark]

Sure, it's fine.

[quick cargo]

What you shouldnt do still though is expose it without a reverse proxy really

[jade lark]

There is downsides as I pointed out.

[quick cargo]

Aiohttp has a bunch of stuff

it's not exactly a under-supported library

being the largest and most used async http library around

I still recommend putting the server behind something like Nginx because it protects you from all sorts of nasty and also allows for things like HTTP/2 which can boost performance

[jade lark]

A reverse proxy does *not *boost performance in most cases. Using it though is highly recommended though due to the security benefits.

[quick cargo]

In Pythons world it can, although typically not many people will actually make use of the the extra wiggle room it gives

HTTP/2 from client to proxy does add significant benefit though in terms amount of connections the proxy can handle vs the amount of requests it can process

[jade lark]

That is very very unlikely even in Python. The important part is using something such as gunicorn or uvicorn

[quick cargo]

due to the single connection multi-plexing

[jade lark]

Right, but a reverse proxy can only handle so much traffic itself. For example, look at something such as Kestrel.

[quick cargo]

yeah, although that number will be significantly higher than anything you write

[jade lark]

Unlikely 🙂

[quick cargo]

not really

Proxies are very simple setups in terms of CPU time

by the time you have to add your database logic etc...

[fast charm]

hi guys, im learnining django-rest and i need a bit of help

[quick cargo]

your application behind it will take considerably longer

[jade lark]

Uh yeah, that's an IO problem.

not related to a reverse proxy

[quick cargo]

Things like Nginx and Apache have also got decades of optimizations behind them

[jade lark]

Yes, but that doesn't mean it makes your server faster.

[quick cargo]

In most cases the raw execution speed is faster

[austere relic]

Think that another reason for reverse proxy was that you can run many aiohtttp instances

[quick cargo]

you can do that anyway

all python webservers rely on the pre-forking web server model to function properly

[jade lark]

If you're going to be scaling horizontally absolutely it's needed. It should always be used.

But saying it's faster 🤦‍♂️

[austere relic]

well, that's what the docs said idk

[jade lark]

Instances could mean multiple things. You're not wrong you're good.

[quick cargo]

I mean the docs do say it

Just call aiohttp.web.run_app() function passing aiohttp.web.Application instance.

The method is very simple and could be the best solution in some trivial cases. But it does not utilize all CPU cores.

For running multiple aiohttp server instances use reverse proxies.

No idea why though

I imagine it's referring to the fact that it's process management will be better than anything you setup in all likely hood

[jade lark]

Instances could be related to being instances spread across servers.

Or it could be if you had two instances running on the same server performing different tasks.

[quick cargo]

Nah, context for this is referring to a process

[jade lark]

Then yes you would want a reverse proxy.

Right but that's not what nginx does...

[quick cargo]

Mostly from aiohttp's perspective it's referring to not being able to fully use the CPU

[jade lark]

You would use uvicorn if you wanted to create more instances of the application.

[quick cargo]

well, you'd use gunicorn because it has better process management

[jade lark]

With an async server?

[quick cargo]

Yes. If you read the uvicorn docs it recommends you use gunicorn with the uvicorn worker rather than uvicorn just by itself

[jade lark]

That's still using uvicorn though?

[quick cargo]

Its a uvicorn worker

Not uvicorn managing the processes or sockets though

[jade lark]

Bruh

[quick cargo]

Im talking in terms of the main controller not the workers

[jade lark]

Ask the question

[jade lark]

Okay, well regardless of all that. Why would you want to make a server with aiohttp over fastapi, django, flask, etc?

[quick cargo]

Well generally, its lightweight and has reasonable performance / good performance in comparison to the others, Eco system tools are also reasonably solid, most ASGI setups are compatible with aiohttp anyway.

The single process server is also possible the nicest thing in the world to deal with when deploying at scale vs dealing with blobs of gunicorn instances

Makes me wish there were more servers that supported a no-watcher process mode

[fast charm]

im getting this error when creating a superuser from a custom model user
TypeError: create_user() missing 3 required positional arguments: 'rut', 'first_name', and 'last_name'

and now im trying to find something so the superuser just require email and password, can it be done? or do i need to make another usermodel or something

[jade lark]

Do you have a user manager or an object manager?

[fast charm]

yes (im following a guide)

        """
        Create and save a SuperUser with the given email and password.
        """
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)
        extra_fields.setdefault('is_active', True)

        if extra_fields.get('is_staff') is not True:
            raise ValueError(_('Superuser must have is_staff=True.'))
        if extra_fields.get('is_superuser') is not True:
            raise ValueError(_('Superuser must have is_superuser=True.'))
        return self.create_user(email, password, **extra_fields)

[jade lark]

Is there a noticeable performance difference? If so do you happen to have benchmarks or reference for it with the code? (Genuinely curious).

[quick cargo]

Generally no real performance difference in the real world in comparison to other ASGI frameworks

[jade lark]

Why use it over something with a bigger community? Besides gunicorn I see very little reason. Unless you're making a very small project

[quick cargo]

It doesnt really have any smaller community compared to other setups

not in the ASGI world

like i said

aiohttp is the biggest async http libary in python

[jade lark]

For the request aspect, yes I can understand that it doesn't. (Does have a decent sized community)

but I have not yet seen or heard of anyone using it in production for a server

[quick cargo]

People use, probably more than things like starlette or quart tbh

[jade lark]

Can you share the user model?

[jade lark]

Right. Which is why I was saying that you probably shouldn't use it unless you have a very specific use case or reason. It would make more sense (at least to me) to go with something that has a bigger community and more information available.

[fast charm]

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    date_joined = models.DateTimeField(default=timezone.now)

    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=20)
    email = models.EmailField(_('email address'), unique=True)
    user_type = models.CharField(max_length=20)
    rut = models.CharField(max_length=20)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    objects = CustomUserManager()

    def __str__(self):
        return self.email```

[quick cargo]

generally it's a pretty solid choice if you want to go with the asyncio route

[jade lark]

You need to provide those three required fields when creating the user model through the cli.

[fast charm]

ok, then if i want to not use the fields can i make another custom user only for the superuser?

[jade lark]

Well, the more you know I guess.

[jade lark]

Uhh, no don't do that please. Make the field not required. You should keep a single user model as that's how Django was created to be used.
null=True, blank=True on the fields. Or, you can provide a default value default='something'

[fast charm]

yeah but that make the fields not required when making a user account right? in that case i should make them required on the frontend or smt

[jade lark]

That is right.

You should be validating user input with a serializer though. You can specify that the field is required on there.

[fast charm]

okk, i didnt know that, im still making the models, serializers is that comes next thanks!

[jade lark]

No worries. You can also update the UserManager to require the fields. If you're new to drf you might have a bit of a harder time figuring out how to override the serializer.ModelSerializer if you're inheriting from it.

[fast charm]

oh yeah i got one method "create_user" that ask for values of the fields

[jade lark]

That's for all users

add the logic in the create_superuser function

[fast charm]

ohhhh right, because when i user manage.py createsuperuser i got the error, so if i update the create_superuser it should ask me for the fields when i createsuperuser (?)

[jade lark]

You'll have to test that one since it's been a while for me

You can always test if it exists in the extra field, or provide a default value for a extra_field

[fast charm]

ok i think i get it, thank you very much

[jade lark]

No problem! Best of luck

[ember skiff]

Does anyone know if there is a way to scrape fb data

[austere relic]

https://scrapy.org/

you'll need to know CSS and HTML though

[ember skiff]

But ppl say scraping fb isn't legal n stuff

[austere relic]

Make up your mind

[ember skiff]

Fb scraping sorry

Coz I tried with sessions and request

It says 505 error

[austere relic]

do you know html?

[ember skiff]

Yep

[austere relic]

hmmm okay

[austere relic]

FB is probably going to give some problems

with authentication

and the likes

So maybe use selenium instead

[ember skiff]

credentials = {"email":"your_email", "pass":"your_password"}
login_basic_url = 'https://mbasic.facebook.com/login'
def parse_html(url):
with requests.Session() as session:
post = session.post(login_basic_url, data=credentials)
parsed_html = session.get(url)
print(parsed_html)
return parsed_html

parse_html(url)

See this... I did this.... Gives 505 error

[austere relic]

sorry, I don't know how FB auth works

[ember skiff]

In the credentual part u just put in ur email n password

The authentication gets done

Also u need to explicitly male a url variable with the link to the post u wanna scrape

[native tide]

how do I do an external request in flask? etc:

headers = {
"rbx-authentication-ticket": csrftoken
}
requests.post('https://auth.roblox.com/v1/authentication-ticket/redeem, headers=headers)```
but within a flask  app.route endpoint

[shy hatch]

Hi, I'm using FastAPI and trying out Form rn, it forces you to provide a default value, but I don't want that, I just want it to return an error when the Form field is not found, is there a way for that? Or will I have to use Form(None) and check for NoneType myself?

Something like this:

@app.put("/user/new", response_class=ORJSONResponse, response_model=UserBase)
def user_new(username: str = Form(None), password: str = Form(None)):
   if not (username and password and len(username) > 2 and len(password) > 4):
        raise HTTPException(status.HTTP_400_BAD_REQUEST)

[small arrow]

this has to be a joke.

please don't do that ever running a web app with root is a massive security risk

any bug in the app will give users probably the access to the server with root privileges.
I know no one uses flask for publishing but I won't trust using this even at the localhost
since any testing and modifying to the database will maybe make your database files locked
with root only can edit to them.

[wind dove]

On top of that, if someone is asking a question like that they must not know a ton about Flask or whatnot.

[small arrow]

Yes I agree. Flask is mainly used for web apps and doing that with knowing that it's for web apps can't be real.

[tribal jay]

Heyo, I'm trying to set up a Quart website along with an attached API at the /api endpoint. I've looked at the quart-openapi extension but I'm not sure if using the Pint from there means the entire website is works under the docs methods there and whatnot or if I can just designated a specific endpoint for it like with flask_restful. Not sure if I'm making sense, but any help would be much appreciated!
I'm wondering if I should just use normal Quart and make my own endpoints since it's just fetching data based on URL query args

[median loom]

sorry couldn't answer your question but do you know if django accepts new requests in parallel without having to resort to async?

[tribal jay]

No worries, never used django so can't help either 😦

[median loom]

oh ok thanks anyway

hope your question gets answered

[tribal jay]

You as well 🙂

[elder echo]

How can I make a multi page layout for my website?

I want it so when you click stuff in the navbar it prings you down

[median loom]

what do you mean pring?

if you want to link a url you can use <a href="link></a> or js

[fallen marsh]

I guess he meant bring

[median loom]

oh

[fallen marsh]

Yea, use a link and add that inside a <div></div>

ezy

[median loom]

<div onclick="window.location.href = link;"></div>
could be used too

Are Django rest framework applications vulnerable to XSS and SQL injection attacks?

[cyan pine]

Would i talk about selenium here?

[inland oak]

it depends on your choice of its usage

[cyan pine]

parallel execution of multiple tabs or windows with different links

[inland oak]

https://docs.djangoproject.com/en/3.2/topics/security/
protected if you setup it right

[inland oak]

for which sort of task?
well, there is #async-and-concurrency channel which can help more about parallelism

selenium is quite webby, so here is approriate too

[cyan pine]

well, im just trying to execute code on 12 different websites all at the same time

and i havnt found a thing on it

[inland oak]

https://stackoverflow.com/questions/42732958/python-parallel-execution-with-selenium
There are links to even github project which makes it
https://github.com/testlabauto/local_selenium_pool

Additionally those testing tutorials can be checked
since selenium is needed for paralled runnin in them
https://www.lambdatest.com/blog/pytest-tutorial-parallel-testing-with-selenium-grid/
https://www.browserstack.com/docs/automate/selenium/getting-started/python/run-tests-in-parallel

Further googling is available with "selenium parallel execution python"

[cyan pine]

thanks for the reply, although ive actually have seen all of these before, i just dont understand them completely i didnt know if they fit my objective. i will look into them further

[inland oak]

I am trying to fit my API into having nice best practices REST logic

I have actions
customer register -> /customer [POST]
customer login -> what is it best url path for this? -> /customer/login [POST] -> perhaps this, since it created token for authentification
customer data -> ...? I would prefer having JSON payload, but GET request I think is not supporting it, I could fit into query parameter though -> /customer [GET]
customer update -> /customer [PUT]
customer send verify email -> API url: /customer/email [POST]
customer verify email -> API url: /customer/email [PUT]

well, probably above URLs will fit me better than what I did before

[slim skiff]

For dev you don't need much

you just need to point your browser at localhost on the port django is configured to use

One of my college tutors has said that when classes start up in September we're gonna be doing C# ASP for web backend because it's industry standard. I kinda don't wanna do that cos I already know Django.

Is it viable to go for a full stack career with Django as my backend system?

I'm trying to format a date created by the django API

render() {
    const { blogList } = this.state;
    return (
      <context.Consumer>
        {({ a, getFormatDate }) => (
          <section className="blog-list">
            <h1>Blogs {this.state.a} </h1>
            {blogList.map((blog) => (
              <article className="blog" key={blog.id}>
                <h2>{blog.title}</h2>
                <hr />
                <div className="blog-body">{blog.body}</div>
                <p className="blog-author">{blog.author}</p>
                <span className="blog-date">{getFormatDate(blog.date)}</span>

            ))}
          </section>
        )}
      </context.Consumer>
    );
  }```

In my component

this is the function I am using ```jsx
getFormatDate = (date) => {
console.log(date);
return new Intl.DateTimeFormat("en-GB", {
dateStyle: "full",
timeStyle: "short",
}).format(date);
};

But I get this error when the component is rendered.

RangeError: Invalid time value

this is an example of what kind of time values are passed to the function 2021-05-26T19:57:47.353005Z

[austere relic]

maybe like this?

new Intl.DateTimeFormat("en-GB", {
      dateStyle: "full",
      timeStyle: "short",
    }).format(new Date("2021-05-26T19:57:47.353005Z"))```

are there any methods of getting the file size in bytes from FastAPI's UploadFile? or do we have to write the data to another temporary file and use that to determine file size?

[ruby sorrel]

hello there, hope everybody is having a good day.
new to programming. just started learning python a month ago.
trying to understand json files and accessing them through python
if i wanted to update a json file,

i was wondering if there was a way to append to it directly instead of having to re-write the whole file?

import json
# currently I understand that i first need to
# load the information on the json file as a variable
with open("test.json") as json_file:
    jf_var = json.load(json_file)
# and when i want to add information on to it,
# i add it the variable.
jf_var["feb"] = "february"
jf_var["mar"] = "march"
# but when i write it, to the json file,
# i feel like there is a more efficient way
# intsead of just re-writing the entire file
with open("test.json", "w") as json_file:
    json.dump(jf_var, json_file, indent=4)
# is there a way to just kind of append to the json file maybe?

[outer apex]

https://stackoverflow.com/questions/12994442/how-to-append-data-to-a-json-file

json objects have a syntax that means the whole object must be read and parsed in order to understand any part of it
Hence there's no way to append data not already in a file. If this part is not taking up too much time, just stick with it. Otherwise there are a couple of other options you can look into for storing data!

[ruby sorrel]

i see. thank you

the way jinja inheritance works is something like this

</body>
</html>

{% extends "snippetAbove.html" %}
{% block head %} head {% endblock %}
{% block head %} content {% endblock %}

instead of this, is there a way to fill the blocks from one parent with multiple files?

<!DOCTYPE html>
<html lang="en">
<head>
    {% block from "head.txt" %} {% endblock %}
</head>
<body>

I need help with async views in django. I get this error when I try to access my async view: ValueError: The view emailbot_dashboard.views.exclude didn't return an HttpResponse object. It returned an unawaited coroutine instead. You may need to add an 'await' into your view.

async def exclude(request): 
    try:
        guild = request.session['select_guild']
    except KeyError:
        return HttpResponseRedirect('guild')
    guild = 762450334513365002
    if guild:
        data = {"guild":guild[1]}
        
        excluded_channels = await get_excluded_channels(data)
        channel_names = [channel.channel_name for channel in excluded_channels]
        excluded_channel_form = ExcludedChannels(channel_names, True)
    return render(request,"Excluded.html", {"chosen_guild": guild[0], "form":excluded_channel_form})```

[autumn hedge]

@stable hemlock you need to add the async keyword into your route method

in flask its: but I could be wrong since i'm learning how to use async myself 😆

@app.route('/async/<something>')
async def my_async_request(something):
  my_async_response = await exclude(something)
  return my_async_response

[chilly trail]

which cms to use for django?

[stable hemlock]

There is not a decorator like that in Django.

[opaque rivet]

try return await render(request,"Excluded.html", {"chosen_guild": guild[0], "form":excluded_channel_form})

[stable hemlock]

Ok.

[autumn hedge]

Does anyone know which version of Flask is NOT multi-threaded?

[median loom]

so did it work?

[autumn hedge]

nevermind. app.run(port=8080, threaded=False) multithreading appears to be available since 0.12.5

[stable hemlock]

I am not at my computer at the moment. Will try later.

[median loom]

oh ok

that issue has been troubling me as well

[peak lava]

    form = UserCreationForm()
    if request.method == 'POST':
        regForm = UserCreationForm(request.POST)
        if regForm.is_valid():
            regForm.save()
            return redirect('login')
        else:
            for msg in form.error_messages:
             messages.error(request, f"{msg}: {form.error_messages[msg]}")
             print(msg) 
    return render(request, 'registration/register.html', {'form':form})```

so for some reason this line of code will always print me the following message on screen "password_mismatch: The two password fields didn’t match.", even tho the passwords match but the problem could be for example, password hasnt met the min_lenght, it will still print the above message, any solutions to this?

[outer apex]

I assume messages.error... and print(msg) is all correctly indented in your code?

form.error_messages should be regForm.error_messages right?

[peak lava]

let me try that rq

yeap still the same thing happens

[outer apex]

Can you share UserCreationForm?

[peak lava]

how

[outer apex]

Oh I meant like copy and paste the code for that form on here? If it's too big a pastebin of it would be great.

[peak lava]

i dont have such code

its an import from django.contrib.auth.forms

[outer apex]

Ah I see. Can you share what you have in your template?

[peak lava]

this is what i could find on django docs of it

    """
    A form that creates a user, with no privileges, from the given username and
    password.
    """
    error_messages = {
        'password_mismatch': _("The two password fields didn't match."),
    }
    password1 = forms.CharField(label=_("Password"),
        widget=forms.PasswordInput)
    password2 = forms.CharField(label=_("Password confirmation"),
        widget=forms.PasswordInput,
        help_text=_("Enter the same password as above, for verification."))```

now that i look at it myself

i can see whats the problem

but how do i customize this

[outer apex]

What were you thinking of customizing?

[peak lava]

well

apparently

in this class only one type of error message is defined

and thats the one where password doesnt match with conf_password

my problem is

there is more errors that happen UI wise when it comes to registering

for example if i were to try entering password thats shorter than defined min_lenght for passwords

i want the error to be displayed as "Please enter a password that consists of 6 or more characters."

and not "'password_mismatch': _("The two password fields didn't match.")"

If it's just password length you're concerned about, I'd say use the minlength/maxlength attributes. Saves you some time having to develop this piece..

You’ll see a message for each migration it applies. If you’re interested, run the command-line client for your database and type \dt (PostgreSQL), SHOW TABLES; (MariaDB, MySQL), .schema (SQLite), or SELECT TABLE_NAME FROM USER_TABLES; (Oracle) to display the tables Django created.

[rustic wave]

Many people in #846514617261621292 have created web apps that will coordinate with other people as to where the pixels will go... where do I start learning how to do something like this?

[gritty cloud]

well this is where the fun begins @rustic wave

i havent used the Pixels thing

it sounds cool

[rustic wave]

is cool*

[gritty cloud]

so the way this works (as far as i know)

you send a request to an api that pydis has

[rustic wave]

ya no i get how it works
but i dont get where do i get started learning to be able to do something like this

[gritty cloud]

first you need to pick a framework

i would use django

but flask would probably be better for this

next

send some requests

[rustic wave]

ive messed around me django and flask a tiny tiny bit...
django brianpoped me
flask made a bit more sense

[gritty cloud]

django kinda does that

it is more effective for large and scaled projects

so next

make some requests

you can use the requests module

!pypi requests

[lavish prism]

requests v2.25.1

Python HTTP for Humans.

[gritty cloud]

@rustic wave

[rustic wave]

yup ik how to use requests

quite familar with it

[gritty cloud]

ok cool

so now we send requests to the api

idk what it is

probably has some docs to it

[rustic wave]

so any good resources to learn something like flask?

[gritty cloud]

flask documentation

tutorials on youtube

[rustic wave]

ya no ik how to interact with the pixels api.. my question was how to make something like pixels

ok ty!

[gritty cloud]

@rustic wave i found this playlist to be quite helpful while i was learning

https://www.youtube.com/watch?v=2e4STDACVA8&list=PLCC34OHNcOtqJBOLjXTd5xC0e-VD3siPn

it covers practically everything

[rustic wave]

ty!

[gritty cloud]

wait haang on

you want to make something like pixels?

[rustic wave]

ye

[gritty cloud]

and not just interface with it, but build it yourself?

[rustic wave]

ye

ik how to interface with it

[gritty cloud]

o wow this just got a lot harder

[rustic wave]

lmao

[gritty cloud]

so if ur building this

you really have no choice but to use django

it has the best database support

[rustic wave]

ah ok

[gritty cloud]

uh so you would probably need to learn it

[rustic wave]

and what about something like this
https://subsystems.bast-development.com/

[gritty cloud]

what is it?

@rustic wave

[rustic wave]

basically it will coordinate between multiple ppl

and tell them where each pixel will go

so liek basically a hivemind i guess

[gritty cloud]

uh i guess

but that rlly isn't neccesary

@rustic wave

we should let the people collab

and do whatever they want

we also would want mods on our db

to check for any criminal ... uh ... imagery

Hey so

https://www.worldometers.info/coronavirus/#countries this is the website

import requests
from bs4 import BeautifulSoup 


h = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36'}
r = requests.get("https://www.worldometers.info/coronavirus/#countries") 
c = r.text
soup = BeautifulSoup(c,"html.parser")



main_table = soup.find("table", {"id":"main_table_countries_today"})
print(main_table.find_all('tr',{"class":"odd"}))

and this is the code

why would it return an empty list ?

cuz we see there are rows tagged with tr and class 'odd'

[haughty gazelle]

Hey why u block me

[austere relic]

I'd suggest you always test your patterns in the chrome console first or use the python interpreter to test them

I did it ,nvm

I want to use this module to create certificates for my domain, but there's a few things I don't understand. Why does it end up with a .crt file? Thought certificates have the .pem extension?

https://github.com/diafygi/acme-tiny

https://docs.python.org/3/library/ssl.html#ssl-certificates

also if anyone has a suggestion for a better way of creating certificates, then I'm open for that

ey is flask worthwhile?

[magic sparrow]

As always, it depends what you want to build

[outer apex]

If you open that site on a browser, notice that there's a delay before the table gets populated? I assume that there's some JS that populates the table after it initially loads. You might want to inspect the HTML you get with requests and scrape using that instead of looking at what's on the browser.

From the initial load, it seems that there are already tables with data, but there are no classes associated with each tr elements.

[random lava]

Hi, got a simple flask demo.
I render template with data=data

When i use {{ data }} in html it works

however in js, var data = {{ data }} doesn't work. How would i do it ?

[median loom]

i'm thinking you must've separated the js file

the templating probably works only on the html file

[random lava]

even if i try it in the console it should be defined correct ?

[median loom]

wait, what should be defined?

[random lava]

if i used console.log({{data}}) for example

[median loom]

nope

the {{ }} formatting is processed at the server

before being passed unto the client

meaning the {{ }} tags are removed before it reaches the browser

[austere relic]

I don't understand the purpose of these records?

[thorn igloo]

you use them when you want a custom domain to point to your server

[austere relic]

isn't that just an A record?

[thorn igloo]

looks like dns to me

[austere relic]

yeah, I meant like "custom domain to point to your server" isn't that just an A record?

[thorn igloo]

not sure what the technical definition is

[peak lava]

                messages.error(request, form.error_messages["msg"])
                print(msg)```
any reasons why these lines of code in views.py upset my compiler so much? it displays "KeyError 'msg'" as an issue
```class UserCreationForm(forms.ModelForm):
    error_messages = {
        'password_mismatch': _('The two password fields didn’t match.'),
        'password_short': _('Password is too short.')
    }```
this is the dictionary im trying to access and get values from

[inland stirrup]

its basically a record telling that go to this ip if you hit a particular domain name also the ns2.digit.........com is digital oceans library of sorts full of records that map/point you to an ip address or to a server

[peak lava]

nvm i've figured whats wrong

Question.

Django related. If I want to update a propert of a object but the property is dynamically ?

How can I do that ?

*property

For prop in list:
Object.prop = value

[vestal hound]

setattr

[native tide]

Only with setattr ?

I have fixed it right now.

[vestal hound]

huh then what do you expect

[native tide]

I have used the update method on the object.

[vestal hound]

what kind of object is it

[native tide]

Can you maybe explain your question

@native tide Hey, I saw your inquiry in the Flask Discord about securing an API. I too am working on an API in Flask, and I will likely run into the same issues you are. I'd love to see what you discover.

Additionally, I was going to recommend JWT, but I don't have much direct experience working with that in Flask.

[inland oak]

You are currently using your own name server. Ns records allow delegating this task to another provider, if I get it right

[austere relic]

[median loom]

padding?

[astral pagoda]

Can someone help with python imports in #help-pie

[median loom]

yeah padding in css

[vestal hound]

padding wouldn't be a space between the elements, technically

you can look into flexbox

what exactly do you want to do?

[median loom]

oh ok

[vestal hound]

you can think of it this way: padding is between everything in the element and the border, and margin is between the element's border and the next element's border

[median loom]

oh ok thanks for the info

[short wave]

someone know why when i try to load my html files i get this?

how its rn:

[marsh canyon]

can you show index.html

I would recommend separating your html from css and js

css, js and images come under static files

https://docs.djangoproject.com/en/3.2/howto/static-files/

[short wave]

i did it from a html builder

[marsh canyon]

you need to handle static files in a diff way.

the link I sent above has all the details for it ☝️

I would recommend you to also look into template inheritance

Hi, is it possible to pass arguments through a redirect?
So like:

data=1
return redirect("/", data=data)

flask btw

[inland oak]

request only minimum necessary amount for current render

pagination is supported at API frameworks level usually

keeping somewhere hidden data, which you do not render, is usually a bad practice

[autumn veldt]

hi this is my main code : ```py

from fastapi import FastAPI

discord_token = "BotToken"

app = FastAPI()

@app.post('/discord-user')
async def discord_user(id):

user_id = id


headers = {'Authorization': f"Bot " + discord_token}

r = requests.get(f"https://discord.com/api/users/{user_id}", headers=headers)

data = r.json()
hash = data["avatar"]
data["avatar"] = f"https://cdn.discordapp.com/avatars/{user_id}/{hash}.png"
data["avatar_gif"] = f"https://cdn.discordapp.com/avatars/{user_id}/{hash}.gif"

return data

this is the test file:

```py
import requests

r = requests.post("http://127.0.0.1:8000/discord-user", headers={"id":"690099836963651695"})

print(r.json())

i get ```
{'detail': [{'loc': ['query', 'id'], 'msg': 'field required', 'type': 'value_error.missing'}]}

y ?

[gray creek]

I think you need to pass them into the data kwarg and not the headers kwarg

Try that out, @autumn veldt

i.e. requests.post('url', data={'id': whatever})

[autumn veldt]

ok

I'm building a django app where I want to run cron jobs based off data that currently exists in the database. Once the cron jobs are complete I want to send a put request back to my django server and update with the new date (or modify the db object with the ORM using a task script whatever is easier). I am looking at celery for this and seems like it is what I'm looking for but not totally sure. Anyone know if there's a better option? I haven't really worked with cron jobs/task runners and stuff before

[inland oak]

celery is better than cron

you will have total control at your code level about your tasks

[opaque rivet]

why is celery better than cron?

i don't really know anything about cron, which is why i ask

[inland oak]

https://www.reddit.com/r/Python/comments/m2dg8/explain_like_im_five_why_or_why_not_would_celery/
read here different reasons

as for purely my reasons... cron lives outside of application. python at best can be only accessing its internal control.
while celery lives basically purely inside your code project and only uses Redis database as memory storage to work.
I prefer having things like that tightly packed into my code project

[opaque rivet]

yeah I guess if you deploy, having it all centralized in a .py file is easiest

surely celery uses cronjobs itself

[silent owl]

@inland oak cool thanks for confirming that for me. As long as I can perform actions on the DB and schedule tasks based on DateTime fields that's all I really need. Sounds like i should be able to do that fairly easily with it

What is the best way to query an existing URL API via Flask application?

[worthy lake]

Whats wrong with margin-top?

Then put a container up there and leave it empty. And when they do the thing, select the element and put the thing in there.

So what you have is

<div class="global-container">
  <div class="container-for-new-thing"></div>
  <div class="container-for-buttons">
    <!-- the code you have above -->
  </div>
</div>

And when you create the element of the thing that you add with JS, you select that container for where to put it

Which is just an empty space already there.

you would probably use more appropriate classes

But that is why you see every element always is contained in a millions divs

i am getting an error: django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. when trying to deploy to heroku. Any idea?

[silent owl]

i would start out checking that your requirements.txt matches your settings.py INSTALLED_APPS object

i always found that part of deploying to heroku to be a pain point

but im noob

obviously you wouldnt need to worry about local app directorys being included in that

i'd also look at your traceback to see at what package it is failing with

[scenic turret]

Should I be putting everything in the requirements into the installed apps?

[silent owl]

not necessarily

copy paste both to me please

try committing to heroku again and see what the traceback says as well, it will show the specifc package it is having trouble with i think

Hi. Have a quick question about the use of webapps for certain stuff

Trying to create a website "hybird"(?) with django. Right now I'm on the part of creating a homepage... do I use the main app, or create another?

Watching a tutorial, and the person used the main app

already created another and I'm somewhat worried it wasn't necessary, because then I'll have to delete it somehow

[vestal hound]

by "app" do you mean "Django app"?

[rustic sky]

yeah

err, project

[vestal hound]

huh?

app orp roject

they're two different things

[rustic sky]

I'm (still) very confused

but

err, app, yeah

two apps in my project... the main one, and then one I created that may not be necessary anymore

[vestal hound]

a project

contains one or more apps

you can think of apps as plugins

that can be added/removed at will

to change the functionality of the project

[rustic sky]

yeah

[vestal hound]

in general

each app has its own sphere of responsibility

for example, say you're designing Instagram

you might have an insta_images app to handle image processing, insta_chat for chat, insta_store for the store, etc.

[rustic sky]

oh, yeah

okay, well....

either this person in a tutorial I'm seeing set it up somehow in the video or not... but he created a views.py and other things in what looks like his main app to create a homepage

do I do this... or should I keep the other app I created and put all the stuff there...?

[vestal hound]

that depends

on your planned architecture...?

I can't answer that question for you

but

it's probably not somtehing yu need to worry about rihgt now

[rustic sky]

honestly, I'm not sure now lol

[vestal hound]

just

stick to one app

if you're starting out

this is not something you need to care about

[rustic sky]

my big worry is deleting the extra one and breaking stuff

[vestal hound]

then don't delete it

just leave it there

guys i have a form like the img
how i can make when someone click on the Search button he get the name input of the first area to go to a link like: link/input_name?
example: www.google.com/ab

is the site static or using any framework?

[short wave]

its static i think . _.

[marsh canyon]

have you worked with js before?

[short wave]

never

i mean i did 9 years ago . _.

[marsh canyon]

you will need some js to make that happen 😄

the process would be to listen to the click event on the button and then read the content of the form input field

then redirecting the user

[short wave]

actually he use something like:

<form action="https://www.itemsearch.com" method="POST" class="u-clearfix u-form-custom-backend u-form-spacing-15 u-form-vertical u-inner-form" style="padding: 10px;" source="custom" name="itemsearch" redirect="true">
...
<div class="u-align-center u-form-group u-form-submit">
              <a href="#" class="u-border-0 u-btn u-btn-round u-btn-submit u-button-style u-custom-font u-font-lobster u-gradient u-none u-radius-50 u-text-black u-btn-1">Search<br>
              </a>
              <input type="submit" value="submit" class="u-form-control-hidden" required="required">
            </div>

i was thinking if i could just change the form action to have something like in python: form action="link/"+var_input

not sure how that would be done tho

Hello everyone! I am using Flask and SQLAlchemy. Is it possible to relocate the Flask routes and the model from the app.py file to their own respective file?
My app.py is awfully long and it would be easier to read if it is possible, but I can't seem to figure out how to do this!

[inland stirrup]

i don't really understand your question but your problem is really long app.py right?

of course you can
create functions in another file and use import at the beginning of app.py to be able to use them
so you just have to invoke the function in app.py

Thank you for your reply. Well I am specifically moving my Flask @spare ridge.routes to another file. I tried moving them, and then importing the initialized app = Flask() to another file, but it didn't work.

[inland stirrup]

do see the link i provided what you need is blueprint hierarchy file structure

[slim beacon]

Another peculiarity is that the routes module is imported at the bottom and not at the top of the script as it is always done. The bottom import is a workaround to circular imports, a common problem with Flask applications. You are going to see that the routes module needs to import the app variable defined in this script, so putting one of the reciprocal imports at the bottom avoids the error that results from the mutual references between these two files.

This is what I needed!

[inland stirrup]

what?? um no its not done like that ..... i really suggest you go to that link or search for blueprint to scale flask app

[slim beacon]

that is from that link

it was a copy paste

also, it doesnt work lol

[tidal slate]

Hi! I have some difficulties in implementation of validate() method for ModelSerializer.
So, there are some rules that check if data that is gonna be saved to db is valid.
The problem is that in case of update this should be checking against merged instance and validated_data
and for create I should perform checks for validated_data only

Using 2 different serializers feels not DRY to me.
Checking for self.instance and validated_data.get("field_name") is also kinda ugly, especially when it is partial_update

Is there some elegant approach to it?

[drifting crater]

you can ask here or DM me

[peak lava]

from which django library do you import "auth_login"?

nvm found it

[arctic shard]

I'm planning to make an image api
I will be using heroku as my host (I don't know where else I could host the api for free ofc since it's only a project)
But since heroku reverts back to its original form when the server restarts the images will be deleted so I need an online database Do you guys know any?

[calm plume]

Are you storing image links or files?

[arctic shard]

Files

[calm plume]

Ah, then no idea

[arctic shard]

Is Firebase a good one?

What about if I store the file as bytes

https://cdn.discordapp.com/emojis/788882232441307154.gif?size=64

[arctic shard]

If they were image links what would you have recommended

[calm plume]

Firebase, Mongo, Supabase, anything

[arctic shard]

Supabase is still in early version but do you have something that is SQL?

[dull pier]

@arctic shard you may still use firebase. You just have to convert image to base64 (so it outputs as a string) and put it in firebase

https://stackoverflow.com/questions/37352884/save-base64-encoded-image-to-firebase-storage

when you fetch base64 from firebase and want to render it as an image on html -> https://stackoverflow.com/questions/8499633/how-to-display-base64-images-in-html

links look dated, you may just do something on the same lines. Firebase API must have changed in 5 years

[arctic shard]

But I kinda wanted to have tags for each image so using firebase will make it bad

[dull pier]

You may also use custom metadata attached to a file on firebase: https://firebase.google.com/docs/storage/web/file-metadata#custom_metadata

I ain't selling you Firebase 😆 just that if you have really trivial use cases then you could just use it simply

[arctic shard]

I found this
https://www.freesqldatabase.com/register/

Completely free database hosting
Instant account activation
5MB of database space
24 hour support

Is 5MB enough? https://cdn.discordapp.com/emojis/788882232441307154.gif?size=64

[quick cargo]

Err for images -> Probably not

also base64 encoding images generally leads to alot of bloat

an image api on a free Heroku instance is probably not the best idea

[arctic shard]

Just a project for testih and understanding APIs

also I shouldn't store images as base64 because it might will bad?

[quick cargo]

well there isnt anything wrong with base64

but it will increase the storage size

[arctic shard]

I thought it will be smaller since string

So using firebase as database is better than using sql database for images?

[quick cargo]

Err they're probably all equally bad

I mean you might only be storing a few images and serving a few images

in which case you might? get away with it

[arctic shard]

Equally bad https://cdn.discordapp.com/emojis/586031051068014612.gif?size=64

[quick cargo]

but any sort of load on any of these cloud databases or free tiers will probably blow through your allowance in no time

[arctic shard]

I don't have allowance

[quick cargo]

the allowance the free tier gives you

e.g. the amount of usage your allowed before it cuts you off

[arctic shard]

Firebase gives 1gb storage https://cdn.discordapp.com/emojis/788882232441307154.gif?size=64

[quick cargo]

thats just storage

that doesnt include the bandwidth cap

If you want my advise: just store the images on heroku

[arctic shard]

What do people with proper hosting do with their images?

[quick cargo]

generally store them as static files or use a CDN setup

[arctic shard]

Cdn like

https://cdn.discordapp.com/emojis/788882232441307154.gif?size=64

This right?

[quick cargo]

idk how discord has their setup but generally its something like a cloudstorage setup and served globally, or its stored in a managed database

But either way you blow through bandwidth rather quick with image serving

[arctic shard]

If they are generally stored...
The system copies the file and give it to the user?

[quick cargo]

pretty much

theirs alot more going on under the hood

[arctic shard]

https://cdn.discordapp.com/emojis/586031051068014612.gif?size=64

[quick cargo]

I recently wrong a setup for this sorta thing https://github.com/ChillFish8/lust

[arctic shard]

I can't find any api reference for this stuff

[quick cargo]

their is a surprisingly low amount of info around this stuff.

mostly because no real good solutions exist ig

but the setup i linked to above is definitely not suited to low ram, low storage servers

[arctic shard]

is this cdn like?
https://docs.thecatapi.com/

[quick cargo]

Ig you can call it that?

In most cases it's probably just a bunch of static files being served by nginx

[arctic shard]

Tbh I'm trying to make a ||thigh|| api 😳 And I kinda wanted it to be open source so static Posting the images in github might get me in trouble

[quick cargo]

Mm for end use I dont think it would be a good idea to try run it on a free server

Ping when anyone is telling a solution going to sleep bye

[mossy hamlet]

Hello!
I have deployed a Flask application on a server but all routes return a 404. The central log of the server is unreachable for me due to the provider.. so I'm looking for ways to test or call routes from python side to try to see potential error messages.

This 404 on all routes is a big black box for me and I can't find the culprit line.

PS: App runs on my local, but the server deployment is using apache and wsgi.. hence the difference.

How can I find the error?

Hi I need help in django.
I've just started learning it and until now i've been using manage.py runserver <ip address:port> to run my django project. I've heard that it shouldn't be used for deployment, that it's just for testing if it works.
Any advice on deploying my django project to a server??

[inland oak]

Gunicorn as standard... but there are alternatives.
https://docs.djangoproject.com/en/3.2/howto/deployment/

[median loom]

ohh so gunicorn is the standard

i see

thank you very much

[inland oak]

You will need handling static files differently

[inland oak]

In addition to gunicorn

Best practice to handle static files with nginx

[median loom]

ok noted

[inland oak]

In advance you need to apply manage.py command

Which gathers all your static files

In one folder

[median loom]

it's in the manage.py help right?

[inland oak]

Should be mentioned here

[median loom]

ok thanks

[inland oak]

I remember manage.py collectstatic I think

It requires some settings changing

[median loom]

oh ok, it's the STATIC_ROOT right?

[inland oak]

Not remembering

[median loom]

ok thanks for your help

i can probably handle this already

[inland oak]

U a welcome

[teal bane]

hey guys i have a school project that consist to do an app of scanning network equipment's like switches and routers i did the python scripts in a traditional way but now i need to integrate my work in a web app but every thing is stuck i never used django before i even tried the simplest things to add a bootstrap page no success i dont know how use the scripts in this web app i feel so lost and time is ticking please any help

[median loom]

if you need something simple and quick, you should use flask instead of django

the directory structure is much simpler compared to django's

@teal bane

[teal bane]

hello

@median loom can you guide me please

[median loom]

i haven't actually used flask that much

i once started a project with it but quit halfway

but flask is simpler and a easier to learn than django

[teal bane]

you dont know neither django or flask ?

[median loom]

i know them

and have used them both

but i don't have much experience and expertise

[teal bane]

my work is not so hard i i stated i need authetication then a form then send the infromation to script script do its job return response if you can please help me

[median loom]

sorry i've kinda forgotten how to work with flask

[naive rock]

I'm working on a program that makes requests to several different APIs(GET, POST, PUT). Mostly Get and and PUT. Right now the project takes roughly 40 minutes to finish mainly because for PUT, I can only update 1 item at a time.

How can I make it fast? I looked into multithreading and came across gerequests. Is gerequests something I should look into?
https://stackoverflow.com/questions/38280094/python-requests-with-multithreading

[vestal hound]

I believe you want async

[naive rock]

I'm seeing some asyncio and aiohttp

https://www.twilio.com/blog/asynchronous-http-requests-in-python-with-aiohttp#:~:text=Making a single asynchronous HTTP,while waiting for a response.

Actually I'll give these a shot.

[woeful vapor]

what would be faster asyncio or gevents?

I have a flask endpoint running right now and my bottle neck is this one tasks that does a look of async requests.gets but I feel like my implementation is off

I'm running gunicorn with gevent config and regular flask. The flask app is monkey patched with gevent so in theory my async stuff should execute pretty fast

[woeful vapor]

    loop = get_or_create_eventloop()
    future = asyncio.ensure_future(multiCallPrice(tokentemp))
    prices = loop.run_until_complete(future)

Idk why but I have this in there it’s the only way I can get it to run

def get_or_create_eventloop():
    try:
        return asyncio.get_event_loop()
    except RuntimeError as ex:
        if "There is no current event loop in thread" in str(ex):
            loop = asyncio.new_event_loop()
            asyncio.set_event_loop(loop)
            return asyncio.get_event_loop()

async def multiCallPrice(loopOver):
    tasks = []
    timeout = ClientTimeout(total=40)

 

    async with ClientSession(timeout=timeout) as session:
        for token in loopOver:

            task = asyncio.ensure_future(async_get_request(session, url, token['token'], token['decimal'], shareAmount))
            tasks.append(task)

       responses = await asyncio.gather(*tasks)
        return(responses)```

[jolly star]

hey how do you make it such that your flask server is updated every x times
i am using a mysql database and when any database changes are made it doesnt reflect in the webpage

[inland oak]

I think you are looking for a more dynamic frontend with javascript

something like... simple js script which checks from time to time update from your backend, and updates the page

basically client-side code

your backend should expose its data in form of JSON API for this

[jolly star]

no idea what that is but i think i should explain it again
i added a record to the database and restarted the flask app the change was there
but when i removed that record and refresh the page the record stays
so i think i need something that restarts as such my flask app every x times

so the changes are visible every time

the sql is updated

[inland oak]

it is completely not the right approach

you are right now rendering page as fixed HTML document

you need to change output of your information to JSON format and having available at some end point

while rendering your view page with addition of JS code which fetches data from your JSON API endpoint

then you can add to js code some addition, which will check for updates and rerender it automatically

[jolly star]

okay what do i need to do

[inland oak]

I just wrote it.

google for some more information about JSON API and JS fetches

[jolly star]

ok

[grave hawk]

How do you guys do queue management with fastapi?
I have built a ML API deployed on GCP Cloud Run with a docker image but on some cases the response takes time and I would rather it goes into a queue like redis or something. I did achieve that by making a docker compose but then I couldn't deploy docker-compose with CI CD on GCP. I don't want to get into kubernetes as it'll be too complex for a small scale solution like mine.

@digital hinge @opaque rivet thanks both

Hello

So i have this form that lets the user make a poll and add choices to it

It consists of 2 ModelForms on for the quiestion model and the other for the choice model

Here's my forms.py and models.py

forms.py



from django import forms
from .models import Question
from .models import Choice




class NewPollForm(forms.ModelForm):
    class Meta:
        model = Question
        labels = { 
            "questionText":"Poll question"
        }

        fields = ("questionText",)



class NewChoicesForm(forms.ModelForm):
    class Meta:
        model = Choice
        labels = {
            "choiceText":"Choice"
        }
        fields = ("choiceText",)

Models.py

models.py


from django.db import models
from django.contrib.auth import get_user_model
User = get_user_model()




class Question(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE, null=False)
    questionText = models.CharField(max_length=150)
    datePublished = models.DateTimeField(auto_now_add=True)

    def str(self):
        return self.questionText


class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choiceText = models.CharField(max_length=200)
    choiceVotes = models.IntegerField(default=0)

    def str(self):
        return self.choiceText

I want to let the user be able to add as many choices as they want
Like there be a (+) button or (add another choice) in the form in the image above

Oh i forget

Here's my view that handles this page

Views.py

views.py



def newpoll(request):
    if request.user.is_authenticated == True :
        pass
    else:
        return redirect("users:signup")
    if request.method == "POST":
        qform = NewPollForm(request.POST)
        cform = NewChoicesForm(request.POST)
        if qform.is_valid():
            newpoll = qform.save(commit=False)
            newpoll.user = request.user
            newpoll.datePublished = timezone.now()
            newpoll.save()
            cform.instance.question = newpoll
            cform.save()
            return redirect("polls:details", pollid=newpoll.pk)
        else:
            return render (request, "polls/newpoll.html", {"qform":qform, "cform":cform})
    else:
        qform = NewPollForm()
        cform = NewChoicesForm()
        return render (request, "polls/newpoll.html", {"qform":qform, "cform":cform})

Thanks in advance

I created token authentication system in Django rest framework, after getting the token, how should I authenticate myself?? any suggestions

is a UI necessary?

[obsidian steeple]

damn i just wanted to try flask

flask is installed

[native tide]

@steel reef UI is not needed. You need to pass the JWT Token (generated in backend) with every other request unter "auth" "bearer <JWT>"

take a look here: https://www.amazon.com/Django-3-Beginners-Andrey-Bulezyuk-ebook/dp/B095V5P2QM/ref=tmm_kin_swatch_0?_encoding=UTF8&qid=&sr=
