Django's built-in test client or pytest?

For testing in a Django project, what should I use Django's built-in test client or pytest?

Or what's the benefit of using one of them instead of the other one?

Recommended Tutorials for Network Programming Using Django as a Beginner?

I’m a network engineer currently studying Django to build a front end for my Python noscript. I’ve started watching some video tutorials and reading through the Django documentation, but I’m still looking for resources that specifically focus on network programming or tools for beginners using Django.

Does anyone have recommendations for tutorials, video courses, or guides that might help someone in my position? Thank you

Open-source Python Uno shuffler

Hi r/Python community! I recently made an Uno shuffler program with python. You can fork it here: https://github.com/LarryEmerson12/UnoShuffler/. It simply just generates the whole Uno deck, and then shuffles it. You can shuffle it as many times as you want.

Target Audience:

You can implement it in your other projects.

Comparison:

I do not know about other projects.

Why is this retrieve method incrementing the viewcount by 2 instead of 1 ? .

class ArticleViewSet(ArticleViewSetMixin, viewsets.ReadOnlyModelViewSet):
    filtersetclass = ArticleFilter
    permissionclasses = (AllowAny,)
    queryset = Article.objects.filter(publisheddatelte=datetime.now(tz=IST))
    serializerclass = ArticleSerializer

    def retrieve(self, *args, **kwargs):
        instance = self.getobject()
        Article.objects.filter(pk=instance.pk).update(viewcount=F("viewcount") + 1)
        instance.refreshfromdb()
        serializer = self.getserializer(instance)
        return Response(serializer.data)


Each time i send a postman request, its incrementing the view\count by 2 instead of 1 ? .
why is that ? .
I also don't have any separate signals or anything, this is the only method I have overridden.

Help needed: Flask not loading images in one template

https://preview.redd.it/isayd97rhd6e1.png?width=900&format=png&auto=webp&s=defc230877ba3f07585cb25cf2693309808682dd

Hello,


I'm new to Flask and having trouble with images in one of my templates (`login.html`). Images load fine when `dashboard.html` using `{{ url_for('static', filename='images/logo.jpg') }}`, but the same code doesn't work in `login.html`. Similarly, the CSS file (`/static/css/styles.css`) also doesn't load for `login.html`.

I've checked the file structure and paths, cleared my browser cache, and tried hardcoding the image paths (`/static/images/logo.jpg`), but no luck. Whenever I load the HTML page separately with the hardcoded path, it works fine.

What could be causing this inconsistency? I would appreciate any help!



**Login.html:**

<header>
<img src="/static/images/logo.jpg" alt="logo">
<!-- <img src ="{{ url_for('static', filename='/images/logo.jpg') }}"> -->
</header>
<footer>
<!-- Bottom-center motto -->
<img src="/static/images/motto.jpg" alt="motto">
</footer>


**Dashboard.html:**

<header>
<!-- <img src="{{ url_for('static', filename='images/logo.jpg') }}" alt="Logo">-->
<img src="/static/images/logo.jpg" alt="logo">
<button class="logout-btn" onclick="
window
.location.href='{{ url_for('logout') }}'">Logout</button>

How to upload files to server using django rest framework (i'm using flutter for the front end)

I'm building a user application which allows user to upload designs for saree's (basically the app is going to be used in textile industries in precise) here i stuck with the file uploading part like how to upload files which are around 2-30mb to the server using DRF.
for context the app is going to communicate with the machine using mqtt protocol so once the design is uploaded to the server it will then be used by the machines.

Please let me know if you have any suggestions on this matter as it would be very helpful.

python-json-logger has changed hands

Hi r/python,

I wanted to introduce myself as the new maintainer of python-json-logger and hopefully establish a bit of trust.

Understandably there has been some anxiety over the PEP 541 Request that I submitted given the importance / popularity of the package - especially in the context of the XZ Utils backdoor earlier in the year.

I think it's important to highlight that although this was prompted by the PEP 541 request, it was not done through PEP 541 mechanisms. In other words this was a decision by the original maintainer and not the PyPI Administrators.

For those wanting to know more about me (to prove that I'm not some statebased actor subverting the package), I'm a security professional and maintain a few other packages. You might also have seen some of my blog posts on reddit.

Finally apologies if the newly released versions broke your things - despite my best efforts at testing and maintaining backwards compatibility it appears some bugs managed to slip through.

Django on ecs

Whats the common practice for serving a Django app from ECS?

Should I use gunicorn from within the container and nginx as reverse proxy?

It’s mainly going to be used as a project to go on my resume so don’t need anything to complex.

Thanks

I don't understand the usefulness of this statement: app.config['UPLOAD_FOLDER'\]

Can't use the os library? Also because I have to constantly change path based on the name of a file.

encoding error

Hi guys, i'm new to coding on flask and python. I'm creating small web application and facing one problem. I input data via textboxes and use my native language while doing it. I am trying to get some data (group and day in def student_show()). After input the error appears, which goes "UnicodeEncodeError: 'ascii' codec can't encode characters in position 11-21: ordinal not in range(128)". I tried to apply .decode('cp1251').encode('utf8'), but got another error "'str' object has no attribute 'decode'". All screeenshots are included. I also included student.html. How can I fix it?

Why does the allowedmethods() function return all http methods even though only get is implemented?

I have a view being inherited by APIView and I have only implemented the GET method in it. But when I call ClassInstance._allowed_methods() I get list of all the HTTP methods even though they are not implemented. When I hit that API with a POST request I get a not allowed error. How could it be?
