Hi,
What is the correct way to set a field value in the form_valid method of a
CreateView? Note the field is not on the form and I don't want to use a
default value in the model.
For example:
def get_state(type_desc, state_desc):
type = Type.objects.get(description=type_desc)
return State.objects.get(state_type=type, description=state_desc)
class CreateFlow(CreateView):
model = Flow
fields = []
template_name = 'create_flow.html'
def form_valid(self, form):
state = get_state("test type", "test state")
# How to set the state field here on the Flow table?
result = super(CreateFlow, self).form_valid(form)
log = Log(user=self.request.user, flow=self.object, state=state)
log.save()
return result
This gives an error because the state field on the Flow table has not been
given a value:
Request Method: POST
Request URL: http://127.0.0.1:8000/create/
Django Version: 1.7
Exception Type: IntegrityError
Exception Value:
null value in column "state_id" violates not-null constraint
Thanks.
