Django Rest Framework - how to create custom error messages for all ModelSerializer fields?

In order to replace unique or regex error messages you should change message member of corresponding validator object. This could be done using separate mixin class: from django.core.validators import RegexValidator from rest_framework.validators import UniqueValidator from django.utils.translation import ugettext_lazy as _ class SetCustomErrorMessagesMixin: """ Replaces built-in validator messages with messages, defined...

I don't understand how Django-Rest-Framework serializers work

There is too much black box magic which confuses the configuration instructions (in my opinion). If there is something in the documentation that you think can be improved, feel free to submit a pull request with an update. If it seems reasonable, it will probably be merged and show...

Assign JSON field to model variable in django

django,django-models,django-rest-framework

If you are using djangorestframework you will need to override to_representation function in your serializer http://www.django-rest-framework.org/api-guide/serializers/#overriding-serialization-and-deserialization-behavior should be something like this def to_representation(self, obj) serialized_data = super(SerializerClassName, self).to_representation(obj) serialized_data["2or4"] = serialized_data["twoOrFour"] //Remove the old field name del serialized_data["twoOrFour"] return serialized_data This code should work where...

Python/Django - datetime dropping the time portion when updating serializer data

python,django,django-rest-framework,django-filters

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...

daterange on a django-filter

I can't speak to the Django REST Framework part of your question, but I hope I can lend some insight to the django-filter part! If you use a DateRangeFilter, the result would be a dropdown with the options "any date", "today", "past 7 days", "this month" and "this year". If...

Django Rest Framework ModelSerialzer field doesn't respect required=False

python,routing,views,django-rest-framework

I added read_only=True to the created_by field, now it's working fine. class CommentSerializer(ContentSerializer): created_by = UserSerializer(required=False, read_only=True) content = serializers.PrimaryKeyRelatedField(queryset=Content.objects.all(), required=False) class Meta: model = Comment ...

django rest framework - using viewsets

You access those actions by specifying the corresponding HTTP method, which is a core idea in REST. Namely, using the HTTP methods to do what their name implies. GET /snippets/ - list the snippet objects POST /snippets/ with POST data - create a new object PATCH /snippets/ with data -...

Add a boolean field if a row exists in another table?

python,django,django-rest-framework,django-1.7

Piggybacking off of dydek's answer here. You overwrite your get_queryset in the Api View class PostList(generics.ListAPIView): ... def get_queryset(self): Post.objects.all().extra(select={ 'current_user_replies_count': 'SELECT COUNT(*) FROM <reply table> WHERE' + 'post_id=posts_post.id AND owner_id = %s' },select_params=(request.user.id,)) This will add 'current_user_replies_count' as a property to the Post objects in your queryset. ...

Django Rest Framework PUT request on unique model field

django,django-models,django-rest-framework,django-serializer

As per the comments implementing the put method closer to the reference implementation in the docs should fix the issue. def put(self, request, pk, format=None): device = self.get_object(pk) serializer = DeviceSerializer(device, data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) Saving instances has a bit more information on creating, updating...

DjangoRestFramework Class Serializers missing “Meta” attribute?

django,python-2.7,django-rest-framework

meta does not equal Meta. Python is case-sensitive.

Django Rest Framework Pagination Overriding

django,pagination,django-rest-framework

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...

customising a model field for serialization

django rest framework - using detail_route and detail_list

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.

DjangoRestFramework - How to pass a serializer form to the frontend?

django,angularjs,django-models,django-forms,django-rest-framework

This must be happening with angular 1.3+. 1.3+ on wards ng-model for date/time input needs to be a valid date object, string representation of date is no longer allowed. You need to convert string to date object ($scope.created_time = new Date(dateString)) and bind it to the ng-model. If you follow...

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...

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...

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...

Django REST Framework : update() based on query string parameter

json,django,django-rest-framework

Assuming you want to use the same url for listing and for retrieving the details of the entity, discriminating on the presence of the url parameter job-def-id, here is a crazy idea: class JobDefinitionsAllInOneView(mixins.UpdateModelMixin, mixins.DestroyModelMixin, mixins.ListModelMixin, mixins.CreateModelMixin, generics.GenericAPIView): queryset = JobDefinitions.objects.all() serializer_class = JobDefinitionsSerializer def get_object(self): job_def_id = self.request.query_params.get('job-def-id', None)...

How to deserialize nested objects with Django Rest Framework

You can pass additional arguments on .save. So I think you just need to pass the newly created book instance to the serializer, e.g. def create(validated_data): chapters = validated_data.pop('chapters') book = Book(**validated_data) book.save() serializer = ChapterSerializer(data=chapters, many=True) if serializer.is_valid(raise_exception=True): chapters = serializer.save(book=book) ...

User registration endpoint in Django Rest Framework

Creating multiple model instances in DRF3

django,django-models,django-views,django-rest-framework

As of Django REST framework 3.1, it is not possible to submit multiple values using form data. This is because there is no standardized way of sending lists of data with associations, which is required for handling a ListSerializer. There are plans to implement HTML JSON forms support, which would...

Is there even any need to use the django rest framework [closed]

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...

Django REST Framework's APIClient sends None as 'None'

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...

Django Rest Framework's serializer.is_valid() raising validation errors even though required=false

Django REST Exceptions

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...

JWT authentication doesn't work for custom controller in Django

I started doing this in comments and it was too long. Generally, you haven't really provided enough code to assist properly, but here's my crack anyway. It's not obvious which version/implementation of Django JWT you're using (there are a few), how you're authorising your views, or whether your calculations.py file...

Django user login through api [duplicate]

django,security,django-rest-framework

Keep in mind using a Django form will only allow you to use SessionAuthentication under DRF - more notes here.

Django test RequestFactory vs Client

django,unit-testing,django-views,django-rest-framework,django-testing

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. The RequestFactory does what it says - it's a factory to create request objects. Nothing more, nothing less. The Client is used to fake a complete...

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...

Django rest framework, JWT and request.session

Is it possible to restrict url access from application only in Dajngo REST

angularjs,django,rest,django-rest-framework

You can't rely on the URL to distinguish between the two cases. You could have your application provide information in the headers of the request, which a browser would not know, but someone writing their own application could mimic your technique.

django rest post return 405 error code

django,python-2.7,django-rest-framework,django-rest-auth

How should I register a new user(custom) in django rest framework?

You are sending a list of files to the view, but you aren't sending them correctly. When you send data to a view, whether it is a Django view or DRF view, you are supposed to send it as a list of key-value pairs. { "key": "value", "file": open("/path/to/file", "rb"),...

django rest framework validation & refreshing data

django,validation,django-rest-framework

Instead of adding field-level validation, add this check to your object-level validation because you require access to multiple fields. Even the DRF docs define this: Object-level validation To do any other validation that requires access to multiple fields, add a method called .validate() to your Serializer subclass. This method takes...

Django Rest Framework Pagination Settings - Content-Range

Using .update with nested Serializer to post Image

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...

django rest framework field level validation in form

Django rest framework: override create() in ModelSerializer passing an extra parameter
