Displayed fields resolve as expected, hidden fields cause errors.
This works:
in the model
CourseBook has a foreign key to Course
In the view:
course = Course.objects.get(pk=whatever)
form = CouseBook(initial = {'course': course})
in the Form:
class CourseBook(ModelForm):
class Meta:
model = CourseBooking
The web page now displays a picklist of courses with the initial value
highlighted. I can now do a form.save() no problem.
However, if I make the course a hidden field, which is what I want.
class CourseBook(ModelForm):
course = forms.CharField(widget=forms.HiddenInput())
class Meta:
model = CourseBooking
then when I come to save() I get a ValueError, unable to assign "My
course" etc. as it tries to put the name of the course into the
foreign key instead of a course instance.
I can work around this putting a save method on the form, but it seems
to me django should resolve this for me????
