Here's my setup (using Django==2.0.6, djangorestframework==3.8.2) I have a basic model (simplified here): from django.db import models class Resource(models.Model): name = models.CharField(max_length=100, null=False) I have a basic endpoint where I can list and create Resource instances: from

问题 django-rest-framework validator accepts string quoted integers as valid data for integer field. Is there a way to mandate data type so that string quoted integers won't be accepted ? 回答1: Serializer keeps raw data in self.initial_data from where custom validation methods can retrieve it.

问题 While using Django-REST-Framework, I am not able to display selected fields in a nested serialized object. I am correctly able to serialize the entirety of the Address model, but I want only a few fields from Address , nested in my serialized Outlet .

The serializer field might be named incorrectly and not match any attribute or key on the Outlet instance. Original exception

问题 This question already has an answer here : Django-Filter Package: How To Filter Objects To Create Stats And Not Lists (1 answer) Closed 4 days ago . Below is the views.py to my stats page. This page has a bunch of calculations based on my model objects. Works great. However when I apply django-filter to the data it does not change. Example filtering for only "short" trades or in the "last 7 days". I know that get_context_data is basically hardcoding the results and it will not be affected by

问题 It is my first project using Django rest framework and i'm struggling to get this right. I know that in mainstream Django framework, if i need to add extra contexts to a class-based view, i will do something like this: class PostDetail(DetailView): model = Post def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) # Add in a QuerySet of all the books by a certain author John context['john_books'] = Book.objects.filter(author=john) return context then, i will be
