Hi all!

I make integration with warehouse system and want to reuse existing
functionality in django.contrib.admin to manage links between this system
and catalog on site.
I can't get access to warehouse system database, I have only export file. I
write some views to represent its items in django admin. And now I need
something like related field in django admin forms, but has some filters
applied to changelist and has some other user interface.

I think, the best solution for this case is put some links with
showRelatedObjectLookupPopup javascript function on admin changelist, but
after user choose the object, my own javascript function must
be called instead of dismissRelatedLookupPopup javascript function.

Execution of dismissRelatedLookupPopup is hard coded in python code now. The
easiest way to implement use case described higher is adding new GET
argument "_callback" to changelist view.

What are you think about this? If this solution was accepted I can write
patch and tests for it.

Cheers!

I think this is a great idea! I would certainly benefit from it.

It might be worth considering if there are any methods for passing a
callback function that are better than GET parameters—though I can't
think of any off the top of my head.

I can't provide better solution too.

I look at the django.contrib.admin source. This can be applied only if 'pop'
argument exists in GET parameters for changelist and  '_popup' argument
exists in GET parameters for adding new item. The changes will be affect to
methods are listed below:

   - django.contrib.admin.options.ModelAdmin.response_add
   - django.contrib.admin.templatetags.admin_list.items_for_result
   - django.contrib.admin.views.main.ChangeList.__init__

Cheers!

Hi I needed to do the same in my own projects, however I just
decorated the functions which I wanted to modify. Like:

original_dismissRelatedLookupPopup = window.dismissRelatedLookupPopup;
window.dismissRelatedLookupPopup = function () {
    // put your own code here ...
    original_dismissRelatedLookupPopup.apply(this, arguments);

};

Maybe this helps until a way is introduced in django to modify this behaviour.

Thank you for sharing good solution, Gregor!
Your solution works great if you has one related lookup. If you need work
with some related fields you must write more javascript code whitch looks
like mankey patching.
