Ohh thanks that helped a lot.
Now in one view I still have a problem.
It uses the a formset and tries to give that back while overwriting the
get_form function:
views.py
class LayoutFormView(LoginRequiredMixin, StaffuserRequiredMixin, UpdateView
):
template_name = 'abc/layout.html'
form_class = LayoutFormSet
breadcrumbs = ['config_list']
def form_valid(self, form):
if 'save' in self.request.POST.keys():
layout_change_settings(form=form, **kwargs)
return HttpResponseRedirect(self.get_success_url())
elif 'reset_to_default' in self.request.POST.keys():
layout_reset_to_default(form=form, **kwargs)
return HttpResponseRedirect(reverse('update_layout', kwargs={
'pk': self.kwargs['pk']}))
def get_object(self, queryset=None):
return LayoutSet.objects.get(settings__pk=self.kwargs['pk'])
def get_context_data(self, **kwargs):
context = super(LayoutFormView, self).get_context_data(**kwargs)
if self.object.label not in ['default']:
context['label'] = "custom"
else:
context['label'] = self.object.label
return context
def get_success_url(self):
return reverse('update_layout', kwargs={'pk': self.kwargs['pk']})
def get_form(self, form_class=None):
if self.request.POST:
return form_class(self.request.POST)
else:
initial = [{'param': 'abc',
'choosen': 'None'}]
return form_class(initial=initial)
forms.py
class LayoutForm(forms.Form):
def __init__(self, *args, **kwargs):
super(LayoutForm, self).__init__(*args, **kwargs)
param = forms.CharField()
choosen = forms.BooleanField()
class Meta:
fields = ['choosen']
def is_valid(self):
return True
LayoutFormSet = formset_factory(LayoutForm, extra=0)
According to my understanding this does not work, because a formset is
assigned to the form_class attribute.
It is not possible to determine the form in the base get_form, because a
formset is assigned.
I would add the formset in the context and then use it in the template. I
still seem to have a problem after saving, but I guess this is releated
with the improper use of the formset.
Thanks for hints.
