I am not aware of a good solution to this problem other than manually adding the .select_related() to your query on the list-of-users page. > I am really unhappy with idea of using custom user model. Why? If it's because this is an existing project and the prospect of migrating your existing data to a custom user model is daunting, I totally understand that. It's doable, but hard. If this is a new project, I think that there is no good reason to avoid a custom user model. Every new project should always use a custom user model, even if to begin with it just inherits from AbstractUser and doesn't change or add anything. This way in the future you have control over your user model and can modify it as needed without monkeypatching.
