How to get Request.User in Django-Rest-Framework serializer?
You cannot access the request.user directly. You need to access the request object, and then fetch the user attribute. Like this: user = self.context['request'].user Or to be more safe, user = None request = self.context.get("request") if request and hasattr(request, "user"): user = request.user More on extra context can be read...
Django Rest Framework - Non Field Error Custom Message
python,django,django-models,django-rest-framework
When you have unique_together set on a model, the serializer will automatically generate a UniqueTogetherValidator that is used to check their uniqueness. You can confirm this by looking at the output of the serializer, and introspecting what Django REST framework automatically generates: print(repr(DeviceContractSerializer())) You can then alter the validators that...

Django rest framework, JWT and request.session

request.session is managed through Django's session framework which requires the use of session cookies and is what powers SessionAuthentication. JWT is completely separate from session authentication, and does not provide a way to store arbitrary data on the token....
Stuck with nested serializer using Django Rest Framework and default user

By default DRF will look at an attribute on the User model named after the serializer's field (member here). However the related name is profile. This can be worked around by passing the source="profile" to your MemberProfileSerializer....
Is it correct to use a ViewSet and the APIView mixins on the same view in Django REST Framework?
django,python-2.7,django-rest-framework
In all versions of Django REST framework, the generic API views and ViewSet classes are distinctly separate, but the mixins can be shared across them. This is because the viewsets actually inherit from the generic classes in the first place. As stated before, you can use the generic mixins though...

Using .update with nested Serializer to post Image
django,rest,django-models,django-rest-framework,imagefield
As noted in the docs, .update() doesn't call the model .save() or fire the post_save/pre_save signals for each matched model. It almost directly translates into a SQL UPDATE statement. https://docs.djangoproject.com/en/1.8/ref/models/querysets/#update Finally, realize that update() does an update at the SQL level and, thus, does not call any save() methods on...

Using Django REST Framework API for data model with composite key
python,django,rest,django-rest-framework
The problem lies into the fact that the DefaultRouter uses the id lookup_field of your model for getting the object you want: For example this works: GET localhost/api/v1/stocksusa/1 In order to provide extra parameters you need to hand-craft the urls like this: url(r'(?P<year>\d{4})-(?P<month>\d{1,2})-(?P<day>\d{1,2})/(?P<code>\w+)$', StocksUsaViewSet.as_view(), name='stocks_detail' ), The year month day...

DjangoRestFramework ModelSerializer: field-level validation is not working
django,django-models,error-handling,django-rest-framework,django-serializer
Field-level validation is called before serializer-level validation.

Instead of adding field-level validation, add this check to your object-level validation because you require access to multiple fields.

This method takes...
How to use PrimaryKeyRelatedField to update categories on a many-to-many relationship

RequestFactory and Client have some very different use-cases. To put it in a single sentence: RequestFactory returns a request, while Client returns a response.

django rest framework - understanding authentication and logging in
rest,authentication,login,django-rest-framework
In a normal web application (removing the API from the question), a user would "log" in with their credentials (username/password, social tokens, etc.) and would receive a session cookie (assigned by Django) that allows them to authenticate in future requests on behalf of a user (realistically, themselves). This session cookie...

Your code is almost correct, you're just the right signature on the register method: def register(self, request): This is the correct signature according to the documentation. Additionally the tests suggest that it's not possible to pass an additional parameter for routing, and that pk will always be passed for a...
Django Rest Framework Pagination Overriding

Using None as the value has the same effect as not setting the paginate_by attribute at all. Have a look at the code of DRF. You'll have to set an explicit value there for it to have effect. As long as we're on the topic, though, the 'PAGINATE_BY' global setting...
Django rest framework generic view for multiple models
A solution would be overriding the get_serializer_class method of the ViewSet.

Of course you don't need DRF. After all, it's just an app that has been written in Python for Django. This essentially means that you can re-create anything you want. However, after a certain point, you'll find you're just duplicating DRF and would probably be better off using it if...

Neither of those is perfect. But View A looks promising. View A is a good start, but it is incomplete solution. Because User creation is not simply User.save, but rather you have to call User.create_user method. View B is the correct way to create user by calling User.create_user, however, the...

how to use django restframework as a backend for mobile apps
I think the easiest way to think about it, is that Django Rest Framework will (normally) return or process JSON data, rather than an HTML page / HTML form data. Your models stay the same. If you use Django's ModelForms then DRF's ModelSerialzers are very similar in use. Likewise, using...

Some actions with object in UpdateAPIView when update
python,django,django-rest-framework
You can get it with self.get_object() Take a look at the source UpdateView, which you are overriding. You can use the same method to get the object: class UpdateModelMixin(object): """ Update a model instance.

Django Rest Framework + React + Reflux: Can't GET new objects
django,reactjs,django-rest-framework,refluxjs
The problem ended up being with the Cache-Control header of the response having a max-age=600. Changing that to max-age=0 solved the issue. In this situation, it doesn't make much sense to provide a cached response, so this I added this to my serializer's ViewSet: def finalize_response(self, request, *args, **kwargs): response...

Django REST Exceptions
django,rest,django-rest-framework
The Django REST framework provides several built in exceptions, which are mostly subclasses of DRF's APIException. You can raise exceptions in your view like you normally would in Python: from rest_framework.exceptions import APIException def my_view(request): raise APIException("There was a problem!") You could also create your own custom exception by inheriting...
Django rest framework sending a string with single quotes back instead of JSON with double quotes
django,python-3.x,django-rest-framework
It appears that leasee = models.CharField(max_length=2000) is a charfield. So Django is simply returning the string stored in this field. Also it is not storing valid JSON string neither because JSON only allows double quote. {'compare': {'uniqueVsChic': '56'}, 'profession': {'hairStylist':True, 'esthetician': True, 'permanentMakeup': True}, 'name':'dfasdfasdf', 'contact':{'facebook': True,'text': True}} looks like...

ForeignKey ListField serialization on rest_framework with django-nonrel
django,mongodb,serialization,django-rest-framework,django-nonrel
The issue here is that you are passing a string (unicode type) to DRF but you are expecting DRF to turn it into a nested representation. Without anything extra, DRF is not possible to do this, as it's way out of the general scope that it tries to maintain. Django...

Django REST Framework's APIClient sends None as 'None'
python,django,django-rest-framework
The problem here is that the APIClient is sending data to the view as form-data by default, which doesn't have a concept of None or null, so it is converted to the unicode string None. The good news is that Django REST framework will coerce a blank string to None...
Python/Django - datetime dropping the time portion when updating serializer data
python,django,django-rest-framework
The problem you are seeing is that you are modifying the serializer data from the outside, which doesn't actually propagate to the data used internally. So even though you are changing the start_datetime and end_datetime fields, internally DRF still sees the datetime objects that only contain the date. You have...
