Stuck with django form validation
I'm trying to get validation running on a django form used to retrieve a list of objects in a ListView View. Despite having read django docs and many other questions here, I can't find out what's wrong in this simple test code:
form.html
<form action="list.html" method="get">
{{ form }}
<input type="submit" value="Submit">
</form>
list.html
<ul>
{% for area in object_list %}
<li>{{ area.name }}</li>
{% endfor %}
</ul>
forms.py
from django import forms
class SearchArea(forms.Form):
area = forms.CharField(label='Area code', max_length=6)
def clean_area(self):
area = self.cleaned_data['area'].upper()
if '2' in area:
raise forms.ValidationError("Error!")
return area
views.py
class HomePageView(FormView):
template_name = 'form.html'
form_class = SearchArea
class AreaListView(ListView):
template_name = 'list.html'
model = AreaCentral
def get_queryset(self):
q = self.request.GET.get('area')
return AreaCentral.objects.filter(area__istartswith=q)
When I try to submit something like "2e" I would expect a validation error, instead the form is submitted. Moreover I can see in the GET parameters that 'area' is not even converted to uppercase ('2E' instead of '2e').

The default a FormView will only process the form on POST; the GET is for initially displaying the empty form. So you need to use method="post" in your template form element.
Your action attribute is also suspect; it needs to point to the URL of the form view. If that actually is the URL, note it's not usual to use extensions like ".html" in Django URLs, and I would recommend not doing so.

Thank you, I didn't read anywhere that validation doesn't work with GET. But, apart from the '.html', django will not make me POST to a ListView...
