assertFormError shows error when testing form input

[KevinS]

Hi all,

I was encountering some issue using the self.assertFormError to test a simple form input.
Not sure why it keeps giving me the following error; I thought once the form is posted, it should be bound.

forms.py

class Form_Test(forms.Form):
    name = forms.CharField(max_length=20)
    integer = forms.IntegerField()
    
    def clean_integer(self):
        c = self.cleaned_data['integer']
        if c < 10:
            self.add_error(
                field='integer',
                error='Must be bigger than 10'
            )
        else:
            return c

views.py

def FormTest(request):
    if request.method == 'POST':
        form = Form_Test(request.POST)
        if form.is_valid():
            print('Hello World')
    else:
        form = Form_Test()
    return render(request, 'basic_form.html', context={'form': form})

urls.py ==> path('test-form/', views.FormTest, name='test_form'),

test_views.py

from django.test import TestCase, 
from django.contrib.auth.models import User
from django.urls import reverse
from ChurchAccount.forms import Form_Test

class AuthViewsTest(TestCase):
    def setUp(self):
        self.form_url = reverse('test_form')

    def test_form_test(self):
        response = self.client.post(self.form_url, data={'name': 'abc','integer': 2})
        self.assertFormError(response, 'form', 'integer', 'Must be bigger than 10')
        self.assertEqual(response.status_code, 200)

    ....

assertFormError() accepts form as the first argument, not a response. Please don't use Trac for support questions as it's not a support channel.

Hi,

Understand that this is not a support ticket and I have already search other forums for a solution. But given your comment and I have check Django documentation, (​https://docs.djangoproject.com/en/5.1/topics/testing/tools/#django.test.SimpleTestCase.assertFormError) and that the parameters are indeed form as first parameter.

That why I am confused as my screenshot shows that the first parameter is a HttpResponse. Hence I have raise it here as a potential bug. But do direct me to the appropriate channel if it is still not an issue to be raised here.

That looks like the IDE has gotten confused and is picking up something else
Doesn't look to be a bug in Django

Hi Team,

Thank you. I tested again, ignoring the prompt from the IDE. It works!

Hello Kevin, I'm glad you are unblocked. But please do not change the resolution option since this is an invalid bug report (it was a support request that should have been sent to the Django User forum).
