I'm trying to create a resource (Observation) that has 0 to unlimited comments. I'm stuck at the following error: "error": "The model '<Observation: Observation object>' has an empty attribute 'comments' and doesn't allow a null value." Also, adding null=True to comments = (...) will result in empty comment objects even though there should be comments for observations in question. I've also tried messing around with CommentResource2 path by changing it to full path. I've been following the reverse relationship guide from Tastypie's documentation: Reverse “Relationships” Here are my models:

Checked some other questions and I think my tastypie resource should look something like this: class MultipartResource(object): def deserialize(self, request, data, format=None): if not format: format = request.META.get('CONTENT_TYPE', 'application/json') if format == 'application/x-www-form-urlencoded': return request.POST if format.startswith('multipart'): data = request.POST.copy() data.update(request.FILES) return data return super(MultipartResource, self).deserialize(request, data, format) class ImageResource(MultipartResource, ModelResource): image = fields.FileField(attribute="image")

I have two models that are linked by another model through a many to many relationship. Here's the models themselves class Posts(models.Model): id = models.CharField(max_length=108, primary_key=True) tags = models.ManyToManyField('Tags', through='PostTags') class Tags(models.Model): id = models.CharField(max_length=108, primary_key=True) posts = models.ManyToManyField('Posts', through='PostTags') class PostTags(models.Model): id = models.CharField(max_length=108, primary_key=True) deleted = models.IntegerField() post_id = models.ForeignKey('Posts', db_column='post_field') tag_id = models

In my Django model, I have 10 fields and there are 3 fields which are foreign keys. In my JSON data which is received from a GET request, I am getting all the fields but not the foreign keys. I have also done this, but I am still not getting those fields in the JSON data: DataFields = MyData._meta.get_all_field_names() class MyResource(ModelResource): class Meta: queryset = MyData.objects.all() resource_name = 'Myres' serializer = Serializer(formats=['json']) filtering = dict(zip(DataFields, [ALL_WITH_RELATIONS for f in DataFields])) For example, I have the field in model like city , but that

Is there a negation filter available by default. The idea is that you can do the following in the django ORM: model.objects.filter(field!=value) How can I do that in tastypie if that is even possible. I tried: someapi.com/resource/pk/?field__not=value someapi.com/resource/pk/?field__!=value someapi.com/resource/pk/?field!=value And all of them given me errors. kgr Unfortunately there's not. The problem is that Tastypie's ModelResource class uses the filter() method of the QuerySet only, i.e. it does not use exclude() which should be used for negative filters. There is no filter() field lookup

My API is returning a JSON object on error but the status code is HTTP 200 : response = JsonResponse({'status': 'false', 'message': message}) return response How can I change the response code to indicate an error? JsonResponse normally returns HTTP 200 , which is the status code for 'OK' . In order to indicate an error, you can add an HTTP status code to JsonResponse as it is a subclass of HttpResponse : response = JsonResponse({'status':'false','message':message}, status=500) Return an actual status JsonResponse(status=404, data={'status':'false','message':message}) To change status code in

I am creating an API with Tastypie and I want to access to the API from Backbone. To send credentials I use an user_id and a api_key. I do this in android and with curl and this work great, but I can set the http header from backbone. In curl I use: curl --dump-header - -H "Accept: application/json" -H "Content-Type: application/json" -H "user_id: 32" -H "api_key: 69950" -X DELETE "http://127.0.0.1:8000/api/v1/deletenote/66/?format=json" and in android java I use: HttpDelete requestDELETE = new HttpDelete(); requestDELETE.setHeader("Content-type", "application/json"); requestDELETE.setHeader(
