Hello,
I am trying to override the Forms in the Django Admin interface to have
custom exceptions in the clean() method.
This works for my first validation, but it doesn't work for a second one in
the same form, or on another form at all. I am wondering if I have the
syntax wrong for multiple validations.
The code looks like this:
class ProviderForm(forms.ModelForm):
class Meta:
model = Provider
fields = '__all__'
def clean(self):
#provider start date and end date
provider_start_date = self.cleaned_data.get('provider_start_date')
provider_end_date = self.cleaned_data.get('provider_end_date')
if provider_start_date > provider_end_date:
raise forms.ValidationError("Start date can't be after end date")
#etqe_id and provider_code
provider_etqe_id = self.cleaned_data.get('provider_etqe_id')
provider_code = self.cleaned_data.get('provider_code')
if "HW" not in provider_code:
raise forms.ValidationError("Invalid provider code")
if "9" not in provider_etqe_id:
raise forms.ValidationError("Invalid ETQE ID")
return self.cleaned_data
class ProviderAdmin(admin.ModelAdmin):
form = ProviderForm
admin.site.register(Provider, ProviderAdmin)
(The first validation, the start date and end date, does work perfectly -
the second validation does not work at all, and allows the form to be saved
no matter what data is entered)
Then I also have replicated this for another form:
class PersonForm(forms.ModelForm):
class Meta:
model = Person
fields = '__all__'
def clean(self):
person_alternate_id = self.cleaned_data.get('person_alternate_id')
alternate_id_type_id = self.cleaned_data.get('alternate_id_type_id')
if person_alternate_id is not None and alternate_id_type_id == 533:
raise forms.ValidationError("Person Alternate ID is not blank, therefore
Alternate ID Type ID cannot be 533")
if person_alternate_id is None and alternate_id_type_id != 533:
raise forms.ValidationError("Person Alternate ID is blank, therefore
Alternate ID Type ID must be 533")
return self.cleaned_data
class PersonAdmin(admin.ModelAdmin):
form = PersonForm
admin.site.register(Person, PersonAdmin)
This does not work at all, and also allows the form to be saved even if the
invalid data has been entered.
Thanks in advance!
