How to clean a certain field in a InlineFormSet?
I need to clean a specific field in an inline formset, and I can't figure out how to do it.
I've tried with the formsets def clean(self)
method but don't know where to save the cleaned va开发者_开发技巧lue. If I try to set the cleaned value to forms[0].data['field']
I get "This QueryDict instance is immutable" error.
In "normal" forms it works by using the def clean_fieldXY(self)
method in which I return cleaned_value
.
Please help.
You can set the inline formset to use a form class, and then you can create a clean
function for the field.
In myapp/forms.py
:
class InlineFormsetForm(forms.Form)
myfield = forms.CharField(required=False, max_length=50)
def clean_myfield(self):
data = self.cleaned_data['myfield']
if data == 'badinput':
raise forms.ValidationError("I hates it!")
return data
Then, in myapp/views.py
from myapp.forms import InlineFormsetForm
from myapp.models import ParentRecord, ChildRecord
def editmything(request):
MyFormSet = inlineformset_factory(ParentRecord, ChildRecord, form=InlineFormsetForm)
