Hi guys,
I got a working model.clean() method that actually does a great job showing
the errors in the assigned html-form. *The view actually marks single
invalid fields red, which I find really important*.
*BUT:*
Now I want to *write a test* for that model and would love to *test for
error_codes*.
*Does anyone know how to raise an error_code-exception within the model and
keep the view rendering the invalid-fields correctly?*
Ok... I think it's easier to understand with some code:
class MyNotebookModel(models.Model):
note = models.TextField()
name = models.CharField()
def clean(self):
errors = defaultdict(list)
# errors = {} # does NOT work with view
# Validate self.note
if 'P.S. I love django!' not in self.note:
message = 'BadAss: Give some credits to Django!'
errors['note'].append(message)
# errors.append(ValidationError(_(message), code=1)) # does
NOT work in view
# Validate self.name
if 'Steven' not in self.note:
message = 'BadAss: I only allow names with Steven'
errors['note'].append(message)
# errors.append(ValidationError(_(message), code=2)) # does
NOT work in view
if len(errors):
raise ValidationError(errors)
class TestMyNotebookCreateView(CreateView):
# in my View I want to show errors by field and mark the error-fields
RED
# it works with the above approach, but NOT with error_codes
class TestMyNotebookModelTest(unittest):
def test_clean(self):
# I'd love to be able to do a test like this one
# and valide the error code!
# Lets get an error-message
with self.assertRaises(ValidationError) as test:
model = MyNotebookModel()
model.note = 'Now this is a valid one. P.S. I love django!'
model.name = 'Britney is gonna fail - Hit me Baby One More
Time!'
model.clean()
model.save()
# validate that the error messages has the right code
the_exception = test.exception
self.assertEqual(the_exception.error_code, 2)
Any ideas how to make this work?
What is best practise?
