What is so dofficult for Django to work out about display media images on my template?
Right, what is so difficult for Django to work out in pertinence to displaying an image on a template when DEBUG is set to False? Why is it, when I do literally everything correctly, does it just outright refused to display the bloody image on the page? Why is it, when I have correctly set up my MEDIA_URL and my MEDIA_ROOT in my settings.py, does it still refuse to load the page? Why is it that despite correctly setting up my root urls.py page in the following fasion, does Django refuse to the display the image in the webpage: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Why is is that, despite correctly setting up the upload_to directly in my models.py file, run the makemigrations as well as the migrate command, does Django....you get the idea. Why is that that despite installing whitenoise, and running the py manage.py collectstatic command doesnt Django...oh yes, sorry, we've done this before. Why is is that when I go to "inspect source" in my web browser does it return the correct image directory, yet when I click on the image URL directory from the inspect source page, does it return my beautifully-crafted custom 404 page?

django rest framework LimitOffsetPagination when modifying results
I'm using django rest frame work and want LimitOffsetPagination https://www.django-rest-framework.org/api-guide/pagination/#limitoffsetpagination to work on the json output of my view class MyList(generics.ListAPIView) which has thousands of records to potentially page through. I can't figure out how to get it working as desired without fetching all the potential records vs only the slice needed for a given page. The problem is introduced by the fact that I have to modify the records before returning from the view, I can't just return a queryset, I return my customized list of records. If I merely do some queryset manipulation and return a queryset, everything works great. SQL to the DB uses LIMIT and OFFSET so it's fast, a page of records is fetched, and json is paged as expected. I need to modify the results of the queryset however and as soon as I evaluate it mylist = list(queryset) SQL does NOT use LIMIT and OFFSET it fetches all the records. If I use slice notation on the queryset queryset[offset:offset+limit] to force it to only get what I want, then modify those results that works up to a point(SQL uses LIMIT and OFFSET etc). The problem is say the slice was 100 records, the … -

Organizing Django Project: Separating App into Multiple Servers with Shared Database and User Model
In our project, we plan to split one Django app from the monolith into a separate server, while using a single database for both. I don't understand how to correctly utilize the user model, which will be shared between the two servers. Should migrations, both existing and future ones, remain in one repository or should they be split between the two? class User(AbstractBaseUser, PermissionsMixin): uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) email = models.EmailField(_("Email address"), unique=True) email_verified = models.BooleanField(default=False) first_name = models.CharField(_("first name"), max_length=100, blank=True, null=True) last_name = models.CharField(_("last name"), max_length=100, blank=True, null=True Explored various architectural options for splitting a Django app into two servers with a shared database. Reviewed Django documentation regarding the use of a shared user model. Expecting to find an optimal way to utilize the user model in this scenario and ensure migration synchronization for both servers -
I want to find a method to avoid complexity and coupling in django models + rest api
I created a model for an API. After that, I planned to add more APIs from different platforms. however, all of the APIs were for the same purpose but the data they required and their methods of accepting the data differ. For example. (it's just an example to explain, not the actual case but 90% similar) I create a model with attributes (name, email, password), but the second API is using (firstname, lastname, email, password). Maybe the third API will ask for (Surname, country, oassword) etc. Then I wanted to create a view to perform CRUD operation. But to know which crud should be done for which API, I created a class with the name CRUD handler in which the class will specify which one to use. I also created another class with the name 'BOT' which had a unique secret key to identify which user wants to use which API. So that every time the credentials are not meant to be sent for safety. Almost all of them use/support the REST framework This is the flow that I want: some_other_WEbsite -> (sends data with secret key) -> djangoview -> BOT ->(uses secret key) to identify the USER, the API … -

window.location.href doesn't adding referer header when executed inside html wrapper but running that in console is adding referer header. Why?
I have two subdomains, let's call them x.example.com and y.example.com. When a user requests x.example.com, the server redirects them to y.example.com. On y.example.com, there's a feature that displays specific content if the referer header matches a certain value. However, when the request comes to y.example.com after the redirection, it doesn't have any referer header attached to it. I'm using Django on the backend to handle the redirection with HttpResponseRedirect("y.example.com"). I attempted to include the referer header in the server's response using Django, but it didn't seem to have any effect. response = HttpResponseRedirect("y.example.com") response['referer'] = 'https://x.example.com' Additionally, I tried implementing a redirection in JavaScript by returning HTML with embedded JavaScript code, but that also didn't result in the referer header being passed along. Interestingly, directly executing the JavaScript redirection in the browser console did include the referer header. I'm puzzled as to why it's not working as expected. Can you suggest an alternative approach to achieve the desired behavior? html_content = """ <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Redirecting...</title> </head> <body> <h1>Redirecting...</h1> <script> // JavaScript code for redirection window.location.href = 'https://y.example.com'; }); </script> </body> </html> """ # Return the HTML response with embedded JavaScript return … -

JWT refresh in Angular 17
My backend is Django restframework. when I give my credentials it gives me tokens which are consist of refresh and access tokens. In my backend my access_tokens expiration time is 2 minutes(just for testing but will increase till 15 minutes). and refresh_tokens expiration time is 15 days. when my access_token expires I send my refresh_token to fetch new access_token(only provides access_token). On front_end (Angular 17), I have implemented to fetch the new access_tokens instead of getting new tokens I am getting logout after 2 minutes. I am new to Angular.

paypal subscription payment doesnt open on django
I am trying to make a subscription using django and paypal payment. I'm trying to complete a course. I have made my plans in business sandbox. I've used the code it gives you after making plans and turn them on. I simply copied and pasted the code into my page. It is a local server. When I click on Paypal buttons they open a blank page.

Are name="submit" and name="next" predefined attributes in Django?
I'm reading a book 'Python Crash Course 2nd edition' and currently doing a Django project. And in a form there are button with name="submit" and and hidden input element with name="next". In the book it says that the button with name="submit" is a submit button and a hidden form element with name "next" is the value argument that tells Django where to redirect the user after they’ve logged in successfully. I tried to search up button with name="submit" and input hidden element with name="next" in Django but wasn't able to find any info. How does it work? Are those somewhere predefined or no? <form method="post" action="{% url 'users:login' %}"> {% csrf_token %} {{ form.as_p }} <button name="submit">Log in</button> <input type="hidden" name="next" value="{% url 'learning_logs:index' %}" /> </form> -

Django form to save m2m additional fields (using custom through\assosiation table)
I have a "Recipe" model, which contains multiple "Product" models and the relationship between Recipe and Product holds the quantity of the products. Thus, I need a custom intermediary model. models.py: class Product(models.Model): name = models.CharField(max_length=50, null=False, blank=False) quantity = models.PositiveSmallIntegerField(null=False, blank=False) ... class Recipe(models.Model): name = models.CharField(max_length=50, null=False, blank=False) ingredients = models.ManyToManyField(Product, through='ProductRecipe') ... class ProductRecipe(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE) quantity = models.SmallIntegerField(null=True) A Recipe object is created based on a form and the Product objects to be part of the Parent object are selected by checkboxes. My question is, how can we add ProductRecipe.quantity field to my form when Recipe object is being created. Here is my forms.py that I use for Recipe object creation class RecipeForm(ModelForm): class Meta: model = Recipe fields = ['name ', ... , 'ingredients'] ingredients = forms.ModelMultipleChoiceField( queryset=Product.objects.all(), widget=forms.CheckboxSelectMultiple ) Trying to have additional field 'quantity' while creating Recipe object from django form -
