How to give priority to a certain field in SearchFilter fields in django rest framework?
I have a simple search api which search the db based on the query parameter provided to the search keyboard. It works fine, but it has some issues. For example, I have a category named Tv and home appliances. It has products like LG speakers and led tv. I have search qeury parameters for both category name and product name. When I search tv, speaksers products are coming in the first page while tv products are coming in the 5th page which I dont want. It is because, category name has Tv and Home. What I want is tv prodcuts to be appear in the first page while speakers to the other pages. For this I have to prioritise the product name field rather than category name. How to do that?? { id:1 category: TV and Home, product: 1500 W Speakers } { id:2 category: Tv and Home, product: Led Tv 32" } I want id:2 to be appeared first then, the id:1, if I search with Tv. class PrdouctSearchAPIView(ListAPIView): permission_classes = [AllowAny] queryset = Product.objects.all() print(queryset) serializer_class = ProductSerializer filter_backends = [SearchFilter,OrderingFilter] search_fields = ['name','brand__name','collection__name','sub_category__name', 'description','variants__color','category__name'] pagination_class = CustomPagination My local endpoint is: http://127.0.0.1:8000/api/productsearch?search=tv My model: class Product(models.Model): merchant … -

Django "No Patterns" / Circular Import Error
I've scoured all of the issues I can find about this error and tried all of the solutions, yet none (save one; more on that later) worked for me. Every time I start up my app, I get the following error: django.core.exceptions.ImproperlyConfigured: The included URLconf 'gamerank.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. I've checked my files for circular imports, and cannot find any at all. voting/urls.py only imports voting/views.py voting/views.py imports voting/models.py, voting/helpers.py, and voting/forms.py voting/models.py imports from libraries only voting/helpers.py imports from libraries only voting/forms.py imports from voting/models.py (which does not import from voting/forms.py) This answer works for me, but I cannot access any of my application after that (because I just commented out the routes), so it's not really a solution in my case.

Is it possible to map all static files or url routes of a website?
I want to make a few static files available in my server, but I don't want people to access it unless they know the exact URL. This is meant to work like a game, solve a puzzle and move to the next phase by finding out the URL. Surely there are several similar games in the web. What I'm worried is if someone could just avoid the puzzle by "mapping" all the static files in a server. Is that possible? [Assuming the puzzle solution would lead to a static file served] I would like to extend the same question for URL routes, is it possible to discover all the url routes of a website? For example I have mysite.com and mysite.com/hidden/solution.html if there are no links to the second URL, can someone get this information? [Except bruteforcing] I'm hosting this page using AWS lightsail (django and apache). Is there something I can/need to do in the django/apache side to prevent this? -
Pycharm Django CSS not updating after adding git repo

Passing an additional field through a model form without adding it to the model
I'm trying to figure out how to add a field to a model form without adding the field to the model itself. I just need to pass in this extra field to the view it returns. My django project has a page where the user uploads a text file which gets saved to the DB (the file upload form is the model form). It then returns a page where the important content from the text file is displayed. I want to add a dropdown on the same page as the file upload form that allows the user to select an option for how the content should be displayed when it returns the next page. I don't want this dropdown to be part of the model for the text file as I don't need to save it to the db.

Django and jQuery: jQuery not working, but receiving no errors

The checkbox has id div_id_newNameBool I have written code that I think should work, but it doesn't. I'm not receiving any errors though, which makes troubleshooting difficult. I'm hoping a second set of eyes can help.

I have a message form and a formset that includes questions for this message. I would like to add textareas in the form, instead of input field. - I am not sure why there are not many examples out there. The models looks like this: class Message(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) message_title = models.CharField(blank=True, null=True, max_length=255) message_introduction = models.TextField() def __str__(self): return self.message_title class Meta: db_table = 'messages' and: class Message_question(models.Model): message = models.ForeignKey(Message, related_name="message_questions", on_delete=models.CASCADE) id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) message_question = models.TextField() def __str__(self): return self.message_question class Meta: db_table = 'message_questions' And the forms look like this: class MessageForm(forms.ModelForm): class Meta: model = Message fields = [ 'message_title', 'message_introduction', ] labels = { 'message_title': 'message_title', 'message_introduction': 'message_introduction', } widgets = {'created_at': forms.HiddenInput(),'updated_at': forms.HiddenInput()} class Message_questionForm(forms.ModelForm): class Meta: model = Message_question fields = ['message_question', ] widgets = { 'message_question': forms.TextInput(attrs={'class': 'formset-field', 'rows': 4}), } Is it doable and if yes, what element of the above code shoudl I change please ? -

I have a TypeError (Object … is not JSON serializable) when I try to set a session value (Django). Why?
I have this strange TypeError raised : "Object of type Product is not JSON serializable" when I try to set a session value in a view (in basket app). The error occurs with request.session['Hello'] = 'foo'. However, this error does not occur elsewhere. For instance, in store app, in views.py, the following request.session['Hello World'] = 'Alloy' works very well. Do you know why ?
