Hi all. Sometimes there is huge amount of related objects. In the effect there is no possibility to delete a model because of http timeout error. Displaying objects to be deleted is quite nice feature, but just unusable in cases like that.
Another thing is that nobody will read 74k related objects. Believe me. It is better to display a summary in that case. To display the summary, a related objects must be counted and this is time consuming process, of course, but we can count them similar way to Collector's fast deletion (using querysets instead of counting models one by one). There is also other design flaw in ModelAdmin.delete_view() - related objects are counted twice: one time for display, and second time after confirming deletion (for request.method==POST). For the second case django is checking only permissions and collected objects aren't used for anything else. Until Django provides no row-level permissions checking those can be done without instantiating all related objects again. I'd like to suggest: - separation of permissions checking from related objects collector, - adding configration option for ModelAdmin.delete_view (to display related objects, display summary, or finally display nothing).
