HI
sorry I wanted to shorten the code before, to not post too much.
Here the code:
views.py
class MFormsView(LoginRequiredMixin, StaffuserRequiredMixin, UpdateView,
MFView):
template_name = 'temps/cnfg_form.html'
form_classes = {
'abc': abcForm,
'md': mdForm,
}
breadcrumbs = ['cnfg_ovw']
def get_initial(self):
return {'pk': self.kwargs['pk']}
def get_success_url(self):
return reverse('cnfg_ovw')
def post(self, request, *args, **kwargs):
return super(MFormsView, self).post(request, *args, **kwargs)
def get(self, request, *args, **kwargs):
return super(MFormsView, self).get(request, *args, **kwargs)
def forms_valid(self, form):
if 'save' in self.request.POST.keys():
change_settings(form=form, **self.kwargs)
return HttpResponseRedirect(self.get_success_url())
elif 'reset_to_default' in self.request.POST.keys():
reset_to_default(form=form, **self.kwargs)
return HttpResponseRedirect(reverse('updt_cnfg', kwargs={'pk':
self.kwargs['pk']}))
def get_object(self, queryset=None):
self.object = ConfigSetting.objects.all().filter(
config__settings__pk=self.kwargs['pk']).get()
return self.object
def get_queryset(self):
self.queryset = ConfigSetting.objects.all().filter(
config__settings__pk=self.kwargs['pk'])
return self.queryset
def get_context_data(self, **kwargs):
context = super(MFormsView, self).get_context_data(**kwargs)
if self.object.label not in ['default']:
# change custom_pump_nr to "custom configuration"
context['label'] = "custom config"
else:
context['label'] = self.object.label
return context
mfview.py
from django.views.generic.base import View, TemplateResponseMixin
from django.views.generic.edit import FormMixin, ProcessFormView
class MFMixin(FormMixin):
form_classes = {}
def get_form_classes(self):
return self.form_classes
def get_forms(self, form_classes):
return dict([(key, klass(**self.get_form_kwargs())) \
for key, klass in form_classes.items()])
def forms_valid(self, forms):
return super(MFMixin, self).form_valid(forms)
def forms_invalid(self, forms):
return self.render_to_response(self.get_context_data(forms=forms))
class ProcesMFView(ProcessFormView):
def get(self, request, *args, **kwargs):
form_classes = self.get_form_classes()
forms = self.get_forms(form_classes)
return self.render_to_response(self.get_context_data(forms=forms))
def post(self, request, *args, **kwargs):
form_classes = self.get_form_classes()
forms = self.get_forms(form_classes)
if all([form.is_valid() for form in forms.values()]):
return self.forms_valid(forms)
else:
return self.forms_invalid(forms)
class BaseMFView(MFMixin, ProcesMFView):
class MFView(TemplateResponseMixin, BaseMFView):
forms.py
class abcForm(ModelForm):
def __init__(self, *arg, **kwargs):
super(abcForm, self).__init__(*arg, **kwargs)
c = model_to_dict(self.instance.abc_setting)
for k, v in self.fields.items():
setattr(v, 'initial', c[k])
if k in ['c']:
setattr(v, 'label', "Active settings")
self.prefix = "abc"
class Meta:
model = abcSetting
fields = ['a', 'b', 'c', 'f',]
class mdForm(ModelForm):
def __init__(self, *arg, **kwargs):
super(mdForm, self).__init__(*arg, **kwargs)
c = model_to_dict(self.instance.md_setting)
for k, v in self.fields.items():
setattr(v, 'initial', c[k])
self.prefix = "md"
class Meta:
model = mdSetting
fields = ['k', 'r',]
In the template it is then used like:
<div class="col-md-3">{{ forms.abc.f }}</div>
As you can see in the ProcesMFView.get, the get_context_data gets the
dictionary form_classes:
form_classes = {
'abc': abcForm,
'md': mdForm,
}
It seems that the Django code is then not able to get the fields and runs
into this error.
Thanks for any hints.
