class AddPackage(admin.ModelAdmin):
form = AddPackageForm
admin.site.register(Packages, AddPackage)
I have a form that I want to show within my admin dashboard. I'm just wondering how can I do something like if form.is_valid() here?
My form has ImageFields which I want to upload to an API before saving anything to my models. Should I just be using signals here? That was my thought, to use pre_save signals.
also saving your models in django admin does not send signals?
void summit
opaque rivet
mhm, I tried pre_save but upon saving my models within the admin dashboard, but I'm not seeing any output. Brief look on SO and someone also said admin doesn't send signals (at least no pre_save - the usual ones).
looking at your post, they have this form:
from models import Product
from django import forms
class ProductForm(forms.ModelForm):
class Meta:
model = Product
exclude = [id, ]
def clean(self):
product_offer_price = self.cleaned_data.get('product_offer_price')
product_mrp = self.cleaned_data.get('product_mrp')
if product_offer_price > product_mrp:
raise forms.ValidationError("Product offer price cannot be greater than Product MRP.")
return self.cleaned_data
They rewrite clean, so could I just rewrite is_valid within my form?
oh iirc is_valid cleans the form first and if there are no validation errors it is therefore valid
so I can just extend clean within my form
that should work
bummer that signals isn't working though

Hello, I am implementing a multi profile user to an existing project. It is for a website that places adverts for selling houses or offices. There is a User model and a UserProfile. We want to have different EstateCompanies where we can assign Users to this EstateCompany with a user that can be a 'normal' user and a 'manager' of the EstateCompany. That said, they also need to get different roles for example a normal user can only see his own adverts and a manager can see all adverts from all users that are assigned to that EstateCompany.. How to approach this?

Hey everyone. I'm trying use cloudinary and got weird situation.
In my model i specified two option ```python

picture_preview = CloudinaryField('image', folder = "media/uploads/home/services/serices-preview/", null=True, blank=True)
When i'm using Django imageField I'm getting image url like ```"https://cloudinary.com/my_image"``` - without format extension.
In second scenario when i was trying use CloudinaryField i'm getting url like
```http://cloudinary.com/my_image.jpg``` with extension, but without https.

opaque rivet
anyone know how to return, multiple querries at the same time in django/rest fra...
I usually just return a response as a dictionary and return .values() of my query
return Response(data={"count": myCount
"query": myQuery.objects.filter().values()}, status=status.200...)
but it has to be serialized through rest framework to work, thats what im trying to figure out
opaque rivet
that would work, the data is returned as JSON, .values() returns a dict.
You could also implement that into your own serializer
wicked elbow
yea, but how. serializers have to be tied to fields or methods. i tried to do the serializers.serializerMethodField to count, but cant get it to work. because the initial is only 3, it only counts 3 in the in response and not a total of all
wicked elbow
# serializer
class SearchProfileSerializer(serializers.ModelSerializer):
class Meta:
model = Profile
fields = ('id', 'username', 'profilePic', 'description')
#api
class SearchProfileApi(viewsets.ModelViewSet):
permission_classes = [
permissions.IsAuthenticated
]
serializer_class = SearchProfileSerializer
def get_queryset(self):
queryset = Profile.objects.all()
search = self.request.query_params.get('search', default=None)
initial = self.request.query_params.get('initial', default=None)
if search is not None:
queryset = queryset.filter(username__icontains=search)
queryLen = queryset.count() #want to pass this
print(queryLen) #this displays correctly
if initial is not None:
queryset = queryset[0:3]
return queryset
if i do the count in the serializer it would be
result_count = serializers.SerializerMethodField()
fields = ('id', 'username', 'profilePic', 'description', 'result_count')
def get_result_count(self, obj):
return obj.user_set.count()
so what's not working here? I'm not seeing it
you could also just give your model a property which returns the queryLen and append it to the data within your response.
I think you just need to return a dict of:
{"queryset": queryset, "count": queryLen}
and you should be sorted, apologies that I have nothing better to say, I'm not familiar with class based views 🥴
wicked elbow
your fine, class based views are nice though. can do it all in one class get, post, delete without any duplicate code

i have a dumb question
can you keep HTML and CSS in the same file?
or do you have to save the CSS stuff as .css

you can have inline CSS
e.g. style=...
otherwise you add it as a stylesheet, and the .css is a separate file
spare iris
yeah i think the tutorial i was following did it as the second option
i have an idea
if i mix both of the tutorials i will get a working flask thing w a login page
then i can add in the sqllite3 that i still have to learn (again)
wicked elbow
its better to be in separate files.
<head>
<style type="text/css">
body {
background-color: #FFFFFF;
}
</style>
</head>
<!-- but this method is better //-->
<link rel="stylesheet" href="stylesheet.css" />
``` the first is document only, the second can be used by allgreat i'll just do the second option then
i kind of forgot HTML/CSS from middle school but i think w3schools is a good source

you can also just add css inline as well <div style="color: #000000">Hello, World</div>

what does div mean again?
it's a container
wicked elbow
be careful with inline though. its the last to be called. it goes
1 .class //called first
2 #id // called second
3 and inline // called last.
``` so 3 will override 1, ect<div></div> is a block container meaning its width=100% of its parent and you can apply padding and margins to it
<span></span> is an inline container meaning its width=fit-content and doesnt respect padding and margins

I've got a custom form within my admins.py which allows me to upload pictures, I then upload these pictures to the imgur API and save the URL within the object in a URLField. The issue is that I can't seem to find out how to also show the URLFields of my model as the ImageFields have the same field name...
class AddPackageForm(forms.ModelForm):
class Meta:
model = Packages
exclude = ['image_1', 'image_2', 'image_3']
image_fields = ['image_1', 'image_2', 'image_3']

image_2 = forms.ImageField(required=False)
image_3 = forms.ImageField(required=False)
def clean(self):
cleaned_data = super().clean()
images = {}
for key in cleaned_data.keys():
if key in self.image_fields and cleaned_data[key] is not None:
images[key] = cleaned_data[key]
imgur = ImgurAPI()
for key in images.keys():
# reads byte string from image
image = images[key].read()
uploaded = imgur.upload_image(file=image)
if uploaded['link'] is not None:
image_link = uploaded['link']
cleaned_data[key] = image_link
return cleaned_data
i dont know anything about that, i do uploads directly to my server instead of uploading elsewhere. wish i could help

Essentially my form field names are the same as my model names, but I don't know how else I can do this (to be able to show both the form fields and the model fields). The model fields are [image_1, image_2 etc.]
I think I just have the wrong train of thought

so basically, you specify some sort of URL that static files are going to be packed in. this can be anything, such as "/css"
so when you use <link rel="stylesheet" href="...">, the href will be the path you specify

Hello. Need some info here
I am a noob learning flask. Which database should I use?
toxic flame
whichever suits u better bro
distant charm
I am thing of postgre or sqlite3
proper owl
sqlite is less complex
if you dont want to dive into client/server architecture of postgre you can use sqlite
distant charm
Alright 😎
marsh canyon
if you have not worked with databases a lot before, then sqlite3 should be good enough for testing/learning flask
distant charm
Aight thanks
noble spoke
Mongo is the simplest
And you can use mongo atlas if you dont wanna setup a local instance
proper owl
sqlite is just a .db file
marsh canyon
I think he wants to focus on learning flask instead of investing time on database setup, here sqlite3 is the easiest to setup compared to mongo, postgres
distant charm
Ik mongo sqllite as well as postgre. I was only having problem choosing one
Thanks anyways ended up using sqllite3

Basically, when you open a website (let's stick to static websites), this is what happens.
- The browser sends a request to a server. It's nothing fancy -- just a small text message formatted in a particular way.
- The server responds with a similar message containing the webpage source (in HTML).
If you install curl and run curl -v https://docs.python.org/3/, if you ignore all the garbage it sends along the way, you will see this request text:
GET /3/ HTTP/2
Host: docs.python.org
User-Agent: curl/7.58.0
Accept: */*
This is the message it sends to the server. It has 4 several important parts:
HTTP/2is the name and version of the protocol, not very important for understanding./3/is the "path" of the URL -- it's the part of the URL after the hostGETis the "HTTP verb" -- it's one of GET, POST, DELETE and a few others. They have some differences, but for now they just bear different meaning, i.e. they allow you to perform different actions on one path- After the first line you'll see a list of headers -- it's a list of key-value pairs with some metadata. For example,
User-Agenttells what kind of program the client is using. - After these headers, you have optional "request body" -- everything before was just the address and the post stamp, but the body is the letter. Here there's nothing in the body.
You can also try https://jsonplaceholder.typicode.com/:
curl -v -X POST --header "Content-Type: application/json" "https://jsonplaceholder.typicode.com/posts" --data '{"title":"foo","body":"bar","userId":1}'
this sends this request:
POST /posts HTTP/2
Host: jsonplaceholder.typicode.com
User-Agent: curl/7.58.0
Accept: */*
Content-Type: application/json
Content-Length: 39
{"title":"foo","body":"bar","userId":1}
Then the server responds with:
HTTP/2 201
date: Wed, 24 Feb 2021 20:50:45 GMT
content-type: application/json; charset=utf-8
content-length: 65
... (some garbage like cookies and such)
{
"title": "foo",
"body": "bar",
"userId": 1,
"id": 101
}
The 201 is a status code -- it tells you the status of the response, i.e. whether it succeeded, how exactly it succeeded or why it failed https://developer.mozilla.org/en-US/docs/Web/HTTP/Status

Hm?
Wdym
I know async won't work, but I don't need it for my use case
glossy arrow
Im making my own framework
I need a server for it to run by default
So I though uvicorn by default would work
Its WSGI
rustic pebble
I don't understand
Uvicorn is based on uvloop which is just another implemention of the asyncio loop
Why would you want to create a sync framework based on uvloop?
spare iris
skrrt skrrt
glossy arrow
Lol
rustic pebble
I am confused
glossy arrow
Well, I made a web framework, it runs by default on a cherrypy webserver, but you can use any WSGI server with it, I wanted a different default web server for it to run, so I decided to use uvicorn, since its fast and can handle lots of requests really well
And the webservers WSGI
spare iris
did not understand a word but go off
glossy arrow
Lol
rustic pebble
The way uvicorn is able to handle so many requests that good is because it is based on uvloop
rustic pebble
You wouldn't be using it for its intended purpose if its not deployed with an async module
like asgi or hypercorn
glossy arrow
I mean, if it works i'm fine with it
rustic pebble
Kinda bad practice but sure
rustic pebble
Basically what you are doing can be summed up to this:
import asyncio
async def count_to_10():
for i in range(9):
print(i + 1)
asyncio.run(count_to_10())
It works but it doesnt look right
rustic pebble
np
You might want to look how fastapi is implemented
It supports both sync and async
and its based on starlette which is based on uvicorn and uvloop
wicked elbow
i dont have a clue what either of you are talking about. i still dont understand the point of async
noble spoke
Its an alternative syntax to threads
rustic pebble
Not at all @noble spoke
wicked elbow
no i understand what async does
async func a () {
await this;
}
async func b () {
await that;
}
``` so it calls a, and runs the code, while it waits for this it calls b, and does that. then goes back to this and gets the response, and finishes the the function call then finishes b. but your still waiting, just for 2 things at the same time.
so on the 6th line this guy writes that
i think that's his path
how do i figure out the equivalent for my computer?
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] ="login.db"
app.config["SECRET_KEY"] = "thisissecret"
db = SQLAlchemy(app)
right now it's just this
rustic pebble
You need to create a database, I suggest you use sqlite
so it gets automatically generated in your project's directory
wicked elbow
but unless your running multiple requests that take a bunch of time, it doesnt really help that much in terms of processing speeds. just running async on everything isnt that benificial
spare iris
idk how to use sqllite3 for logins
rustic pebble
Async has specific use cases and it is mostly for networking
spare iris
i tried following tutorials but i don't understand what's going on
rustic pebble
CPU bound stuff is generally not for python because of its GIL (Global interpreter lock) basically making it unable to run multiple processes at the same time, that can be considered both good and bad at the same time but I won't get into it now because it could be hours of typing haha
wicked elbow
yea, because requests takes time. you get stuck in a queue and get answered when you get answered.
rustic pebble
Kind of
There are many things async can do and it is definitely where the web frameworks are heading in the future
wicked elbow
i mean beasically, without a full course of networking and dbs.

my site is fully async, but i dont actually have to program for async. i use react and axios. its all promise based. but my site still doesnt run full async like others try to program their sites
also not a clue, i use django. but ive never seen either of that
rustic pebble
react and axios are frontend technologies
Your site doesn't have to be written in async for that
wicked elbow
react and axios are both async though. theres not a single page refresh, its all done async in the background
rustic pebble
React is not async
React is a frontend framework for building interfaces
How you interact with your API is your choice
fetch api is async for example
But in javascript async is syntactic sugar for promises
wicked elbow
react/redux/axios is considered async. everything is based off promises. js async isnt true async like python async, but it follows the same concept at least from what ive been told
rustic pebble
Alright, I am not going to get into this argument

react has async qualities, but it isn't really async unless you make it to be

do HTML files count as static files?
static files generally refers to javascript / css files. for frameworks like django/flask the setup for static files excludes that of html files, so I would say it's not considered static within that sense.

axios = async = best request library
Why do you need axios if there's fetch? https://caniuse.com/?search=fetch
axios seems a bit like leftpad or is-number
opaque rivet
i have no clue, I think it's because I learnt axios first
both are really really similar
axios is really simple to use I can say that
and is-number is extremely useful 🤓 🤓 🤓
maybe even thanos.js
manic frost
Well, fetch's interface is pretty much just one function, and it's a built-in.
I guess you can make your own little wrapper if you want something more specific and convenient, but not a large dependency.
One thing I hate about axios is that non-2XX responses are thrown as exceptions.

This'd be the place to ask some Django questions, yeah? Didn't see any other more-specific channels.
wicked elbow
yea, do you have a question?
covert hawk
Yeah, more about deployment of a pre-packaged Django app, looking for opinions on something. Lemme type it all out, gimme a sec.
So, I'm trying to deploy an already-developed Django app. Source is unobfuscated, so it's no mystery on what they're using in the app. The vendor for the app doesn't have great built-in ways to load data into the environment at deployment time, so I'm trying to use some Django built-ins to do it.
By "data," this would be "things you'd normally configure in-app that I don't want to make a human configure in each of our environments" - think like custom categories in this app, user roles for django_prbac, a few other things.
Optimal requirements are that this initial data can be loaded/modified idempotently, is easily versioned (i.e. I can deploy it through my CI/CD pipeline), and easy to parse by human beings
placid vigil
Look into seeding data on django
Found this on the docs: https://docs.djangoproject.com/en/3.1/howto/initial-data/
covert hawk
I figure I have a few options:
- Fixtures: literally designed for loading initial data into an environment, so there's that - but, if they change their data model, those fixtures might not work any longer. Plus, they use ints as their pk, and making it not collide with an existing record while remaining idempotent seems hard without a source code change (can't).
- Migrations: can easily be versioned, and can have it depend on a migration point in their package. Use
RunPythonto have it generate records, modify them if need be. I can then say what max version number of migration gets deployed in the stage. I don't quite know how I'd need to number these, though. - Admin command: most flexible, but also requires the most overhead. Also difficult to say exactly what version gets deployed, tracking those versions would be a bit difficult.
@placid vigil I looked at fixtures, and I'd really want to use them, but:
- can't call out to external libraries (think of if I wanted to resolve a secret value for a superuser password or something)
- I can't get them to run idempotently, if I declare an int pk, I have to hope that they didn't use that value somewhere else. They have UUIDs, but that's not their pk for the model

nah, they are both position fixed. even works correctly in mobile browsers.

so instead of - _ -- i had to use align-items center for them to line up. the overlay is

hey there
I have a basic flask app with this main functionality:
- someone can register on the register page and get redirected to the user area page.
- OR the user can login if he has an account there.
now the problem is I dont want my user area page can be accessed by typing the url in the url bar.
but only from the login or register page through redirection.
Any help?

@barren topaz you need session management... the flask docs have an example of an auth wrapper that's pretty simple
You just apply it to the route and it creates a condition
barren topaz
<@689173943894016140> you need session management... the flask docs have an exam...
In fact I dont wanna use any sort of authentication from flask modules. I have a very simple html form and I wanna do all the stuff by myself.
I can provide my code if that can help.
gleaming tiger
Either way, you need to create a session. the type of session depends on what your needs are. Its just a signed cookie anyways and it uses the session obeject.
barren topaz
I'm sorry pal, Im quite a newbie in flask. Can I send you the code?
Cuz I have implemented the session thing based on the doc. but I dunno what further steps I should take.
gleaming tiger
barren topaz
This is my code, in the user_area function I was trying to put a condition not to let anyone access the page via GET but it seems that was dumb thing.

All of this stuff is covered in the tutorial, everything your asking about is covered in the docs. I know because I just spent about a week reading it over. https://flask.palletsprojects.com/en/1.1.x/tutorial/

@barren topaz if you're interested in all the details, bottle is a micro framework and gives you more fine tuned control. or you can just use weurkzueg which is really getting into the weeds a and is what flask uses anyways.

There may be performance differences but I don't think there is a notable downside.

you should use a frontend framework with django for sure, it makes auth less plug n' play tho :>(
chilly trail
I mean react is awesome and I am also kind of angry learning it so later.
vestal estuary
Yeah, cors was a pain to get past
quick cargo
generally it doesn't matter much which system you use just depends on context
if you have something which relies alot on AJAX type systems like a chat app etc... then a front end framework like react or vue is easier to use and setup
but if it's static content there isnt much reason to use it over ss rendering unless you're planning to render the content on a edge server
