Test Upload Excel File and JSONField Django REST

Question

My

models.py

has 3 fields. One of them is

JSONField()

attribute = JSONField(null=True, blank=True)  # Free to add any note to here

type = models.CharField(max_length=30, choices=FileType.choices, default=FileType.zipcode)

file = models.FileField(upload_to='import_files')

I normally set

JSONField(null=True, blank=True)

for the sake of easiness.

def test_upload_and_process_data_complete_case(self):

    from soken_web.apps.imported_files.models import ImportFile

    with open(str(settings.BASE_DIR) + '/apps/zipcodes/complete.xlsx', 'rb') as uploaded_file:

        data = {

            'attribute': {'author': 'Singh'},

            'type': ImportFile.FileType.zipcode,

            'file': uploaded_file

        }

        response = self.client.post(reverse('api:import_file-list'), data, format='multipart')

        response.render()



        self.assertEqual(status.HTTP_201_CREATED, response.status_code)

And my test runs fine without shooting with

JSONField

Experiment:

When I shoot with

JSONField

like the given. It will failed with this error

AssertionError: Test data contained a dictionary value for key 'attribute', but multipart uploads do not support nested data. You may want to consider using format='json' in this test case.

However, from my understanding I have to post with

multipart

because of

file

.

Question:

Is it possible to do unittest shoot the endpoint that has

JSONField

and

FileField

in the same time?

Answer 1

After played around with parser.
I found that nothing in the configurations are wrong. Only one thing I missed is. I have to put single quote cover the {"author": "Singh"}.
Because web browser does submit in the str not python object.

    from soken_web.apps.imported_files.models import ImportFile
    with open(str(settings.BASE_DIR) + '/apps/zipcodes/complete.xlsx', 'rb') as uploaded_file:
        data = {
            'attribute': '{"author": "Singh"}',
            'type': ImportFile.FileType.zipcode,
            'file': uploaded_file
        }
        response = self.client.post(reverse('api:import_file-list'), data, format='multipart')
        response.render()

        self.assertEqual(status.HTTP_201_CREATED, response.status_code)
