Answer 1

I guess that you want to get a category from a given id.

def test_carete_sub_category(self):
    category_id = 1
    category = Category.objects.get(id=category_id)
    ...

When testing, you have to create some objects in order to check the code works. In this example Category object. If not, this will raise an ObjectDoesNotExist exception

There are several ways to create these objects in your tests. Here is 2 possible ways:

1) You can dump some models of your database in a json file.

Run python manage.py dumpdata myapp.category 1> categories.json , copy it to the fixtures sub-directory of your app and load it as a fixture in your tests

class ProjectTests(APITestCase):
    # This create the objects from dump for each test
    fixtures = ['categories.json']  

    def test_carete_sub_category(self):
         # Get the category object with id 1 defined in categories.json
         category = Category.objects.get(id=1)  
         ...

2) You can create the objects in the setUp method of your TestCase

class ProjectTests(APITestCase):
    # This is called before each test
    def setUp(self):
         the_args_for_creation = {'name': 'bal-bla'}
         self._cat_id = Category.objects.create(** the_args_for_creation).id   

    def test_carete_sub_category(self):
         # Get the category object
         category = Category.objects.get(id=self._cat_id)  
         ...

You may be interested by django-model-mommy or django-factory-boy to make object creation easier in your tests.

Of course, the object creation can be done in the test itself rather than in the setUp . If done in setUp , the objects will be created at the beginning of each test.

I hope it helps
