Is there a way to create dependent fields in Django models?

Is there a way to automatically fill fields based on dependencies? E.g. I have a model with fields answer_type and chart_type, where I want (e.g.) all radio button answer_types to automatically be pie chart_types, and all autofill questions to automatically be bar chart_type.

I don't seem to be able to call functions based on fields within the model, so I'm not sure if this is feasible.

What in particular is preventing you from calling functions based on the model fields? You should be able to define functions within the model, as such:

class YourModel(models.Model):
    answer_type = models.CharField(max_length=20)
    ...

    def chart_type(self):
        if self.answer_type == 'radio':
            return 'pie'
        ...

Let me know any problems you run into with that.
