问题 I am having difficulty serializing an intermediary "pivot" model and attach to each item in an Many-to-many relation in Django Rest Framework. Example: models.py: class Member(models.Model): name = models.CharField(max_length = 20) groups = models.ManyToManyField('Group', through='Membership') class Group(models.Model): name = models.CharField(max_length = 20) class Membership(models.Model): member = models.ForeignKey('Member') group = models.ForeignKey('Group') join_date = models

问题 I'm currently working on an Api build with Django Rest Framework, uwsgi nginx and memcached. I would like to know what is the best way to get users statistics like number of requests per user? Taking in consideration that the infrastructure is probably going to scale to multiple servers. And is there is a way to determine if the response was retrieve from cache or from the application? What I'm thinking is processing the Nginx logs to separate the request by user and apply all the

问题 I have a model and I want to write an update() method for it in order to update. The below snippet is my model: class Klass(models.Model): title = models.CharField(max_length=50) description = models.CharField(max_length=500) university = models.CharField(max_length=50,blank=True, null=True) teacher = models.ForeignKey(Profile, related_name='teacher', on_delete=models.CASCADE) and the below snippet is corresponding Serializer : class KlassSerializer(ModelSerializer): teacher =

问题 I have a tv channel model and created a django-restframework viewlet which gives me a list and a detail view out of the box. On top I added two custom single-object views called all_events and now_and_next_event, as described here: Marking extra methods for routing. That works great so far. class ChannelViewSet(viewsets.ModelViewSet): """ A viewset for viewing and editing channel instances. """ serializer_class = serializers.ChannelSerializer queryset = Channel.objects.all() @link() def now

问题 I'm using Python 3.7, Django 2.2, the Django rest framework, and pytest. I have the following model, in which I want to re-use an existing model if it exists by its unique key ... class CoopTypeManager(models.Manager): def get_by_natural_key(self, name): return self.get_or_create(name=name)[0] class CoopType(models.Model): name = models.CharField(max_length=200, null=False, unique=True) objects = CoopTypeManager() Then I have created the below serializer to generate this model from REST data

问题 After having read through and completed the Django REST Framework tutorial, it is not completely obvious how one would implement a filter on a GET request. For example, ListAPIView is great for viewing all the instances of a Model in your database. However, if I wanted to limit the results (e.g. for a Book model, I might want to limit the results by publication date or author, etc.). It seems the best way to do this would be to create a custom Serializer, View, etc. and basically write
