Mixing
Django Crispy forms - inline Formsets 'ManagementForm data' error with update view
4
Good Evening,
Im having trouble with a crispy forms inlineformset. I have followed guides as per:
https://github.com/timhughes/django-cbv-inline-formset/blob/master/music/views.py
https://django-crispy-forms.readthedocs.io/en/latest/crispy_tag_formsets.html#formsets
EDIT
I think the issue is something to do with the dual submit buttons. the devicemodel form has a button that when pressed produces this error. but there is also a save button as part of the resource helper, when that's submitted I get an empty model form error.
I've added screenshots of what happens when you action each button
and I must be missing something as am getting the error:
['ManagementForm data is missing or has been tampered with']
here is my update view:
class EditDeviceModel(PermissionRequiredMixin, SuccessMessageMixin, UpdateView):
model = DeviceModel
form_class = DeviceModelForm
template_name = "app_settings/base_formset.html"
permission_required = 'config.change_devicemodel'
success_message = 'Device Type "%(model)s" saved successfully'
def get_success_url(self, **kwargs):
return '{}#device_models'.format(reverse("config:config_settings"))
def get_success_message(self, cleaned_data):
return self.success_message % dict(
cleaned_data,
model=self.object.model,
)
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['title']='Edit Device Model'
if self.request.POST:
context['formset'] = DeviceFormSet(self.request.POST, instance=self.object)
else:
context['formset'] = DeviceFormSet(instance=self.object)

I think you have to render management form in your template, explained here why you need that
Management Form is used by the formset to manage the collection of forms contained in the formset. If you don’t provide this management data, an exception will be raised
add this in view html
{{ DeviceFormSet.management_form }}

Your problem is that each form in a formset has its own management_form. I haven't dealt with this specifically in crispy, but in the general formsets, that was the problem that I had. You have to manually spell out each piece of the formset, either by iteration or hardcoding, and make sure that each has its management_form.

I think you have to render management form in your template, explained here why you need that
Management Form is used by the formset to manage the collection of forms contained in the formset. If you don’t provide this management data, an exception will be raised
add this in view html
{{ DeviceFormSet.management_form }}

Your problem is that each form in a formset has its own management_form. I haven't dealt with this specifically in crispy, but in the general formsets, that was the problem that I had. You have to manually spell out each piece of the formset, either by iteration or hardcoding, and make sure that each has its management_form.
