Configuring Django Rest Framework Pagination
The docs for Django Rest Framework say that configuring pagination is as simple as adding the default pagination class and size to settings.py and making sure that you are using a GenericAPIView.

Vscode does not read the css after restart
I'm student of programming and i just started working at yesterday on vscode. I'm trying to make a social/house rent platform by using django/jquerry. I made some html, css, js pages, there is a no problem about this, everything okay and working.. then i slept and today just turned on my pc but vscode didn't read the css files (not sure about js files too). I use href="{% static 'polls/style.css'}" method for calling static files I tried everything but it's still wasn't reading the current files. So i did <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}"> to //the only difference is name of the css file <link rel="stylesheet" type="text/css" href="{% static 'css/styles.css' %}"> and renamed my stlye.css file to styles.css and bang it's working... I thought it was a one time bug but it's not. Before 15 min ago i put my computer to sleep mode and when i came back i solved the same problem the same way.. does anyone have this problem and how can i fix it ? -

GUnicorn not showing up locally, not using any ports (Django)
I am trying to run a Docker container via the command: docker run --rm -d projectname:latest And I get the following gunicorn lines: [2020-07-28 11:56:50 +0000] [10] [INFO] Listening at: http://127.0.0.1:8000 (10) [2020-07-28 11:56:50 +0000] [10] [INFO] Using worker: sync [2020-07-28 11:56:50 +0000] [12] [INFO] Booting worker with pid: 12 From this I thought it was working fine.

search multple values over multiple fields in django filter
I have a Product Model with fields: Name -> CharField (product name) Brand -> FK to a model named Brand (Brand has a name and id) Description -> TextField (product description) I need to make a search for products which would intake multiple values eg. "Nike Black Shoes" where i need to search every word in every field described above. eg Nike would match in brand and Black would match in Description and Shoes would match in Name.. Something like that. Right now I'm using django-filters. https://django-filter.readthedocs.io/en/stable/ from django.forms.fields import MultipleChoiceField class MultipleField(MultipleChoiceField): def valid_value(self, value): return True class MultipleFilter(df_filters.MultipleChoiceFilter): field_class = MultipleField class ProductFilterBackend(df_filters.FilterSet): search = MultipleFilter( field_name="???", lookup_expr="icontains", widget=CSVWidget ) class Meta: model = models.Product fields = ["search"] I can put only a single field in field name so how do I search over all the 3 fields defined above ? If this can be done then is there way to get products ranked according to the amount of match so more relevant products can come above. -
Django - Why should I extend User as opposed to creating my one user class
All, I'm having some difficulty understanding what is the advantage of extending the user class in Django? I feel it's more advantageous to overwrite it and create my own user class, with all the files that I want. I'm asking this because all the tutorials that I see always refer to create a profile class and from there extend the user class. I would see the advantage if I wanted to extend the user class multiple times, but I feel that this never happens.
