For a project I needed to create a Django model from a list of fields that were defined somewhere else. It took me hours to get this to work, so to save you the time, here is the solution:
bc.. fields = ['field_a', 'field_b', 'field_c'] # the base model with some basic fields class MyModel(models.Model): date = models.DateField() # add the extra fields after the model has been created for field in fields: MyModel.add_to_class(field, models.DecimalField(decimal_places=4, max_digits=10))
My first instinct was to create an
__init__ function inside the model class and use that to create the extra fields, but since the
__init__ function is never called for models, this didn't work. Creating the extra fields after you created the model class itself however works just fine.
