Django model inheritance overriding a variable used in field attribute

由 拟墨画扇 提交于 2021-02-08 20:59:37
问题 I am trying to override some default values in a inherited Django model. I have a bunch of different image sizes for models I need and the fields needed are 90% the same. I have tried creating a base model to use and was going to add any additional fields needed to the child models. The problem I am having is that the images are only using the "default" values I have set and are not being overwritten in the child model. Is what I am trying to accomplish possible? Thanks! class ImageLink

I have creating this processor for a ModelForm. Can you please help with this? I am adding the code written so far. It is more of a test code; import
