Trial of dynamic forms looks pretty good and interesting to me.

Thanks, this is exactly what I was looking to do. I was worried it wouldn’t be possible. How did you discover this?

Hey, that is very handy. I now also use this to initialise the forms initial values:

    def __init__(self, referenceModelInstance, *args, **kwargs):
        super(SomeForm, self).__init__(*args, **kwargs)
        self.referenceModelInstance = referenceModelInstance
        for field in self.fields
            self.fields[field].initial = getattr(self.referenceModelInstance,field)

When creating the form I feed it the model for which I want the form to be instantiated. This of course requires the fields to have the same name as the model fields.

Are there any other drawbacks that I am not thinking about with this code?
