Looking for Django recommendations about frontend layer

Hello,

I'm a ReactJS/React Native developper, and for the company where I work today I have to create a new Django project (all the rest of the team is acquainted with Django).

My collegues are mostly backend developpers, and they don't have any experience with react frameworks.

So I'm looking for recommandations about implementing the frontend layer and keeping the Django views philosophy.

I think I will use Bootstrap Javascript and maybe JQuery if necessary. I don't know if there are any "more modern" approachs (but still keeping the views.py files).

So if you have some recommandations, i'm interested.

Many To Many delete relational model if no references exists

Hey guys,

I have this two models:

class X(models.Model):

id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
max_impressions = models.PositiveIntegerField()
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)

class Y(models.Model):

id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
type = models.CharField(max_length=256)
content = models.TextField()
x = models.ManyToManyField("x.X", related_name='creatives')
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)

I am trying to figure out how can I make sure record Y will be deleted if it has no references to X records, but I don't wont it to happen the other way around.
So, if I delete all X records that related to Y, than delete Y
but if I delete al Y records that relates to X than **don't delete** X.

Django CBV: How come my child method is not overriding my parent method?

I'm pretty new when it comes to python classes / django CBVs. I'm trying to have a method (print\_test) from my child class override my parent class, but I can't get it to work. What am I doing wrong?

Below is my parent:

@method_decorator(login_required, name='dispatch')
class Base(View):
print("can you see the parent?")

def post(self, request):

def filter_test(self):

filter_dates, time_period_selection, data_type, loan_type, overflow, slug = filter_test(self)

def print_test(self):
return print("printing from parent")

print_test(self)

def rest_of_it(self):

data, mimetype = rest_of_it(self)


return HttpResponse(data, mimetype)

This is my child:

@method_decorator(login_required, name='dispatch')
# @fold
class RefactorQualityAjax(Base):
# pass
print('can you see the child?')

R Class-Continuous Conditional Generative Nerual Radiance Field

Paper: https://arxiv.org/abs/2301.00950

Project Page: https://tom919654.github.io/C3G\_NeRF/ (Videos included)

Code: https://github.com/tom919654/C3G-NeRF

​

Abstract:

The 3D-aware image synthesis focuses on conserving spatial consistency besides generating high-resolution images with fine details. Recently,Neural Radiance Field (NeRF) has been introduced for synthesizing novel views with low computational cost and superior performance. While several works investigate a generative NeRF and show remarkable achievement, they cannot handle conditional and continuous feature manipulation in the generation procedure. In this work, we introduce a novel model, called ClassContinuous Conditional Generative NeRF (C^(3)GNeRF), which can synthesize conditionally manipulated photorealistic 3D-consistent images by projecting conditional features to the generator and the discriminator. The proposed C^(3)GNeRF is evaluated with three image datasets, AFHQ, CelebA, and Cars. As a result, our model shows strong 3D-consistency with fine details and

smooth interpolation in conditional feature manipulation. For instance, C^(3)G-NeRF exhibits a Frechet Inception Distance (FID) of 7.64 in 3D- aware face image synthesis with a 128^(2) resolution. Additionally, we provide FIDs of generated 3D-aware images of each class of the datasets as it is possible to synthesize class-conditional images with C^(3)G-NeRF.

Starlite development updates January ’23

Hello there fellow Pythonistas, do you have a moment to talk about the web framework of choice, Starlite?

In case you're wondering what the heck a Starlite is, here's a quick elevator pitch: Starlite is an ASGI web framework focused on building highly performant APIs quickly and with ease by providing many tools out of the box such as a stellar OpenAPI integration, ORM integration with SQLAlchemy, Piccolo and Tortoise ORM, type safety using rigorous typing, excellent Pydantic support, and many mechanism for customization.

## So what's new?

The first thing I want to highlight was a much requested feature: Starlite now includes a CLI, allowing to quickly run and inspect Starlite applications, featuring a smart autodiscovery that's not restricted by naming conventions.

The CLI is something we are planning to expand on, u/Goldziher for example is currently working on an TypeScript generator that can generate typing files directly from a Starlite app, using the OpenAPI schema!

In other news, Starlite has succumbed to carcinization; Our query string parsing is now done by a dedicated Rust library. Why? Performance.

As you can see, in this benchmark Starlite handily beats even blakchseep, a notoriously fast ASGI framework written in Cython

What Django admin theme do you use ?

We happily use Django in our company and the plan is that our Key Account Managers will be responsible to manage their customer accounts.

But the feedback I get a lot is that Django admin is scary.

It looks complex with its small button and old school look.

So I want to theme it to make it less scary.

I really like Jolie as a theme, but looking at their website, it looks dead to me. They are asking for 200$ for a beta licence, alongside a button to get notified when it gets live. And I think it's been like this for a year.

So what have you guys implemented to make Django admin less scary for non tech administrators ?

Thanks a lot.

Django authentication works locally but not in PaaS cloud server

I have deployed a Django/Django Rest Framework application to Render and it works well except for the authentication process. I am using PostgreSQL for the database.

​

Authentication is based on Django sessions, and it works in my local server but not in Render, where it returns a 500 server error when trying to log in with some user credentials.

All the other database interactions and APIs work in Render, including registering users in the database. I guess there is some server configuration problem.

​

Any idea about how to solve this?

Render **context as HTML in render_template?

Hello everyone! I'm in the early stages of developing a flashcard solution using Flask. The objective is to have users input HTML for both sides of their flashcards, which will then be rendered when reviewing cards. As a foundation, I have been attempting to develop a simple Flask application that takes an input and parrots it back, rendered as HTML.

I have encountered an issue in that when I return e.g. `flask.render_template("index.html", front="<h1>Hello World</h1>")` on a GET request, `front` here is shown as pure text (escaping tags) as opposed to being rendered as HTML. In other words, instead of a large "Hello World", it displays "<h1>Hello World</h1>".

Example code follows:

# main.py

import flask

app = flask.Flask(__name__)


@app.route("/", methods=["GET", "POST"])
def index():
if flask.request.method == "POST":
return flask.render_template("index.html", front=flask.request.form["front"])

return flask.render_template("index.html", front="Enter something!")

how do i pass a parameter to js function in flask ?

Hello all, i am a python beginner trying to make a portfolio website using flask to show some visualization i created using power bi .

i have followed the MSFT example to apply embedded 1 vis following the example but i am struggling to embedded multiple vis as i not yet able to find a way to pass a variable to to js so that it can embedded the other vis .

The place "VAR" is originally coded as 0 in the MSFT example it make the page only show the first report i have in the list of report id .

I need to assign a value for var (like 0 , 1,2 ,3 for 1st 2nd , 3rd , 4th report) for different "section tag" to extract the corresponding report but i don't know how .

Thank you

Is it good way to send request whenever model update?

I have to post model data to some websites whenever specific columns of models changed.


1) write request function as override model update function.

2) add a function and use it in the view class.


If I apply 1), I don't need to check when I should add a new function to send requests or not. It'll work well whenever the model changes in every function. But It seems pretty dangerous..

2) I should write the code if I add a new function to handle the model. So if I miss writing the function, that'll not send a post request.

which is the better way..? Should I make a function to send a request? or override the update function in the model?
