Unit test for Django Resource containing an ImageField

[silviomoreto]

Hi,

I am trying to write an unit test for my resource, but I am getting the error:

{"error": "Expecting property name enclosed in double quotes: line 1 column 2 (char 1)"}

Here is my model:

class MyModel(models.Model):
    input_image = models.ImageField('Input image', upload_to='process')

My resource:

class MyModelResource(DjangoResource):
    preparer = FieldsPreparer(fields={
        'input_image': 'input_image_url',
        'id': 'id',
    })

    def is_authenticated(self):
        return True

    @skip_prepare
    def list(self):
        return list(MyModel.objects.all().values('id'))

    def update(self):
        raise MethodNotAllowed()

    def delete(self):
       raise MethodNotAllowed()

    def detail(self, pk):
        return MyModel.objects.get(id=pk)

    def create(self):
        form = MyModelForm(self.request, self.data, self.request.FILES)
        if form.is_valid():
            obj = form.save()

My unit test

class CountProcessResourceTest(TestCase):

    def setUp(self):
        self.client = Client()
        self.img_url = 'https://www.djangoproject.com/s/img/small-fundraising-heart.png'
        image = urllib.urlopen(self.img_url)
        self.image = SimpleUploadedFile(name='test_image.jpg', content=image.read(), content_type='image/png')
        self.object = MyModel.objects.create(input_image=self.image)

    def test_create(self):
        api_url = reverse('api_mymodel_list')

        t = {"input_image": self.image}
        response = self.client.post(api_url, t, content_type='application/json')

        print response.request
        print response.content

What am I doing wrong?

Silvio,

probably is a Client problem
look at the ResourceTestCase from Tastypie or Restless tests

In model, tries to use @Property with dict, works for me, and facilitates the use of thumbnail.

class MyModel(models.Model):
    input_image = models.ImageField('Input image', upload_to='process')

    @property
    def get_input_image(self):
        if self.input_image:
            return self.input_image.url
        return None

    @property
    def get_dict_image(self):
        if self.input_image:
            return {
                'url': self.input_image.url,
                # 'width': ...
                # 'heigth': ...
                # 'format': ...
            }
        return None
