How to a call a REST API from a button
I'm a noob with html and django rest. In my router.py I declare my 'route' for "rest/v2" url: router.register(r"export/file/<int:id>/csv", views.IncomingFileExportViewSet, basename="ext-incomingfile-export") What I want to do is to call methods that are in the viewSet when a user press the button in the interface. Is it possible to that from html code or there is a better way? html (the button is export-csv): <div class="dropdown"> <button class="btn btn-outline-primary btn-export" aria-expanded="false" data-toggle="dropdown" aria-haspopup="true" > {% translate "Download" %} </button> <div role="menu" class="dropdown-menu"> <button id="export-csv" class="dropdown-item" type="button">{% translate "csv" %}</button> </div> </div> In another post on SO I read that it is possible using ajax, but I don't understand what should i write. -
Add annotation to all Django ORM queries that go through a model
The Django AbstractUser has fields for first_name and last_name, and get_full_name method. If I wanted to filter Users based on a search of their full name, I can add a custom model manager for the User, that has a method something like this: def filter(self, *args, **kwargs): queryset = super().get_queryset() if any(key for key in kwargs if key.startswith('full_name')): queryset = queryset.annotate( full_name=Concat(models.F('first_name'), models.Value(' '), models.F('last_name')) ) return queryset.filter(*args, **kwargs) Meaning I can do things like: User.objects.filter(full_name='Foo Bar') User.objects.filter(full_name__icontains='foo b') ... etc But of course this will only work when directly filtering Users above. If you have Post objects that are FK'd to a User, then you get this: Post.objects.filter(user__full_name='Foo Bar') ... FieldError: Related Field got invalid lookup: full_name So the question is, is there a way (without modifying all models to have custom managers), to allow Django to always recognise a given term (in this case 'full_name') on all joins to a given model's table, and annotate the necessary value so it can be filtered on? Note: I'm aware I could of course add full_name as a field on the user, and try to ensure that it's always up to date, but I'm specifically trying not to add this denormalised … -

Django CSP Allow iframe from domain without having to set CSP for everything else
I need to allow another domain to embed my website in an iframe. I can use Django CSP to achieve this by setting the following, assuming that example.com is the domain that will be hosting the iframe of my website. CSP_FRAME_ANCESTORS = ("'self'", 'example.com') I would like Django to operate as it does out of the box, which is without CSP (correct me if I'm wrong). In this case, how could I achieve this with my CSP configuration? I currently have this, but it doesn't catch everything, and I'm not sure if it's less secure as Django out of the box, or the same. CSP_DEFAULT_SRC = ("'self'", '*') CSP_FRAME_ANCESTORS = ("'self'", 'example.com') Is this the same as how django operates by default, or have I made my application less secure by configuring it this way? -
ManyToMany django field not working, not taking any input in POST request?

How can I read a file from ajax call in Django?
I'm working in Django. I need to upload a txt file and print its content in a table. I've tried many things but none of them work.
