I'm having trouble dynamically assigning the choices to a ChoiceField.
My ChoiceField stores an object's state. In the template pulldown for
this field, I want to restrict the user to only go from stateA to
StateB; from stateB to stateC, etc. Hence the allowable choices need
to be a set based on the current state (and also user privilege). How
do I do this?
For example
class MyClass(ModelForm)
state_txt = forms.ChoiceField(choices=setChoice())
...
def setChoice():
currentState = ???? #how to get the current object's
state
if currentState == 'stateA':
return [('stateB','stateB')]
elif currentState == 'stateB':
return [('stateC','stateC')]
...
