Getting initial parameters of inline admin model formset using URL

[Manav Agarwal]

We may pass initial Model admin form parameters using URL, visit https://docs.djangoproject.com/en/3.1/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_changeform_initial_data for more details.

#26607 introduces a hook to customize the initial parameters or kwargs for Django admin inline formsets. As per the discussion on the ticket and on the respective PR, It seems that adding a function to initialize formset parameters from the URL would be complex. The purpose of starting this discussion is to have some good suggestions to implement the same and also to confirm that whether we shall implement such function or not.

HI Manav. 

Thanks for your work on the PR! 

I think with the new get_formset_kwarg() method in place folks could subclass in order to add initial data.

This is in contrast to the issue the PR resolves, where there was no real access point to customise the behaviour. 

I’d say that’s the right balance in terms of utility and API surface area. 

Kind regards, 

Carlton
