Static/constant dictionary for get_initial or get_form_kwargs

[Bob Glassett]

Hello, 

Trying to bring a django app into production, and I ran into a real headscratcher.

I have a Class based view inherited from create.  When the page reloads, after validation, I check the initial dictionary for a field's value to fill in the queryset for a different field.

I'm getting sporadic errors about one of the fields not found in the initial object.  When I looked closer into the problem, the initial dicitonary matched a form for a totally different model.

If I need to pre-populate the initial dictionary, I override the get_initial and return the dictionary that I want.  I am not setting initial= in the class definition.  Is this the right way to do this task?

I am concerned about a static initial dictionary sticking around.  The base edit class returns a copy of the initial dictionary, but if the initial dicitonary somehow has invalid values in it, I could be seeing this for all my forms.

This is what I did for the initial dictionary:

class UserCreateView(AdminCreateView):

    model=User

    success_url='/portal/accounts/list'

    form_class=PortalUserForm 

    

    def get_form_kwargs(self):

        kwargs = super(UserCreateView, self).get_form_kwargs()

        kwargs.update({'request' : self.request})

        return kwargs 

    

    def get_initial(self):

        return {}

On a ModelForm (unrelated to the form/model above) I was trying to access the self.initial for a particular field, which threw a Key exception.  The initial dictionary passed down on the yellow screen did not match the form or data for the view at all.

kwargs:  

{'initial': {'agency': <Agency: Baldwin>, 'canEnterMealCounts': False, 'canManageCalendar': True, 'canManageCustomerAllergies': True, 'canManageFieldTrips': True, 'canManageSocializations': True, 'canManageSpecialOrders': True, 'canManageSupplies': False, 'canPrintMenus': True, 'chefablesUser': False, 'location': <QuerySet []>, 'phone': PhoneNumber(country_code=1, national_number=2018158136, extension=None, italian_leading_zero=None, number_of_leading_zeros=None, country_code_source=1, preferred_domestic_carrier_code=None)}, 'instance': None, 'prefix': None}

I have no idea where that initial dictionary came from.  My get_form_kwargs looks like this:

    def get_form_kwargs(self):

        kwargs = super(PendingLabelsCreateView, self).get_form_kwargs()

        kwargs.update({'user': self.request.user})

        return kwargs

The direct ancestor doesn;'t have get_form_kwargs defined, and that is defined as such:

class AdminCreateView(LoginRequiredMixin, UserPassesTestMixin, CreateView):

I need to understand where that initial value came from and determine if I have static values where I don't want them.

Thanks in advance

Maybe they are set in the Form?

 

Thanks in advance
