[Django Admin] Harmonizing obj=None parameter across multiple function

[Sven R. Kunze]

Searching the issue tracker didn't reveal anything useful. Please point me at the right issue if this topic has already been discussed elsewhere. :-)

During several projects, we worked around an issue of Django Admin. When using the following methods:

• formfield_for_dbfield
• formfield_for_choice_field
• formfield_for_foreignkey
• formfield_for_manytomany
• get_field_queryset
• get_autocomplete_fields
• get_changeform_initial_data

the current instance is really useful for complex applications, but it is not provided though.

Our current work-around: reparsing request.path_info and retrieving the object once again. In addition to the code redundancy, it's an additional performance loss.

As a solution, we propose the following:

• harmonize the obj=None parameter across those method like get_fields or get_readonly_fields.

Hi Sven,
The best place to discuss new features is the Django ​forum so I recommend you take this there to get feedback from the community.
I would also say that having a simple/small example of how you've "worked around an issue of Django Admin" would help with this discussion. You may find there are other ways to approach the problem 👍
