Override Field Widget In Django Admin Form âš Timonweb At a minimum i can see needing to modify change form . (or, you could do this by modifying the add form template and change form template attributes of the modeladmin class to refer to your custom template for only those models where you wish to do this.). Because django probably already cached a invalid author before. in order to get a “fresh” author, use the primary key value of the related object as stored in the db field instead. There is a little known hook for dynamically altering the number of extra forms in an inlineadmin. this is exposed in the get extra override.

Unfortunately there is no way to tweak the form instantiation, so our only option seems to be an override for the get formset method on the inline. this option is not as straightforward as it looks like, because get formset needs to return a formset subclass and not a formset instance. We’ll cover overriding the get readonly fields() method for admin models and making inline fields read only based on parent model field values. additionally, we'll dive into a specific case where we need to make inline fields read only based on inline field values, and how to achieve this by overriding the init () method in the inline form. You can override get formset () in your custom inlinemodeladmin subclass to: pass additional arguments to inlineformset factory for fine grained control over the formset's behavior.potentially even return a different formset class entirely (though this is less common). 5👍admin.tabularadmin does not have a get form method. the get form function you defined is never being called.
