Related modal window includes the header.

Python version 3.11

Django version 4.2.9

Package version 0.28.6

Current behavior (bug description) When opening a custom modal window (just adding _popup=1 suffix to the url), the resulting modal window content includes the admin site header.

Expected behavior The resulting modal window content must not include the admin site header.

Investigating what is happening

Clicking the link, the url is loaded in the modal window: https://mysite.com/admin/myapp/mymodel/?_popup=1&_modal=347257

It returns a 302 and then the final url becomes: https://mysite.com/admin/myapp/mymodel/?e=1

The problem is that django, for security reasons filters out unexpected query-string parameters, and in this case the _modal parameter gets appended here just for app specific needs (only if it's not a lookup): https://github.com/fabiocaccamo/django-admin-interface/blob/main/admin_interface/static/admin_interface/related-modal/related-modal.js#L60

---

This behavior, although very useful, is also very limiting in case you want to load custom pages in modal windows and use custom query-string parameters for specific needs.

@merwok do you have any ideas on how this problem could be solved/avoided?

[merwok]

Not sure I understand the comment in related-modal.js

«Browsers stop loading nested iframes with same src» (same as origin page I suppose?) – but why would they be the same? The main page does not have ?_popup=1.

@merwok I don't remember well the nested modals open on the same url issue. Btw, the problem is that if there are custom query-string params it doesn't work correctly.
