Hi, I have a couple of model classes which are in one-to-many relationship. For example, one of the classes is a Product, and another one is Colours.
I know that I can list the acceptable field values in this manner: size_code = db.StringProperty(required = True, choices = ['colour1', 'colour2', 'colour3']) It would be much better if I could generate the list of choices dynamically, depending on what models of the class Colours exist, i.e. the list of available colours can change over time and I would like to avoid having to modify the program code every time there is a change. Why am I doing this? It is because I want to use it with the db.djangoforms.ModelForm class. If I have a list of choices for a field, the ModelForm automatically gives me a dropdown. If there is no list of choices all I get is a plain text entry field. Does anyone know how to address this problem? I tried using GQL queries, but without any success. Python was throwing errors every time I tried to do that.
