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`
{{{#!python
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`
{{{#!python
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`
{{{#!python
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)
....
}}}
{{{#!zsh
