Setting FK field in list view

[RompePC]

I would like to pass to the list display view a FK field of the admin form (like the ones when adding a new row). But I don't see the way of doing it, although I've searched along many properties of the model admin to get it.

Anyone did something like that before?

Have you tried something like author__name ? Assuming a model with an
author foreign key.

I'll try ASAP I can, thanks

Hi again, I didn't have time to try it until now, but I just realized that maybe I asked the wrong way. What I wanna do is to render the widget associated to that FK in the panel, not its name. So I need to pass the field or its rendered content to the context, but I don't know how to do get it.

I looked into it after my first reply and my suggestion was wrong.

If you want to display the value of a foreign key object's property in
the admin page to select an object to change, you can add a callable
to list_display.
For exemple, ` list_display = ('title', lambda o: getattr(o.author,
"name", "-"),) `. The callable will get one argument, an instance of
the model.

If you want to display a field to change a property of a foreign key
object, I haven't found a way. Best option might be a inline model
admin.

Yep, the second one is what I wanna do. Althrough they aren't inlines, but like FK filter choices in the list view (not the default ones).

It's hard to understand, I know it can be done, but don't know how. Will keep searching and throw some light here when done.

Is your request https://code.djangoproject.com/ticket/10743?

[RompePC]

Nope, it isn't a lookup separator: for simply understanding, I wanna get the FK widget (the HTML, the select, all of that) that is show when adding an object that has a related key (say, adding a new City and selecting its Country in the same model, 'cause a City belongs to a Country) so I can use it anywhere in my panel.

ModelAdmin.list_editable?

https://docs.djangoproject.com/en/stable/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_editable

[RompePC]

Nope, as I wanna the ModelChoiceField rendered in the filter list I did in my own (not the sided one).

[Tim Graham]

I still don't understand the goal. Maybe you can mock up a screenshot and/or give a code example.

[RompePC]

Yeah, I'm so sorry, it's hard to understand. I'll post an image of the Django tutorial of what I mean:

I want that the FK widget (the one for Question) could be available in other panel admin's views (as listing) (with no CRUD icons along). The problem is to get the field correctly, as I just only get str representations of the field or the widget.

[Tim Graham]

So basically ModelAdmin.list_editable but without the icons on the side?

If you never want the inline editing buttons for all models, you could override the admin/related_widget_wrapper.html template and remove the buttons.
https://github.com/django/django/blob/master/django/contrib/admin/templates/admin/related_widget_wrapper.html

Otherwise, I'm out of (simple) ideas.

[RompePC]

Talking in the way of getting the HTML widget yeah, maybe. But what I wanna do is, given a model A with a FK a_fk, I want a_fk to be available in views other than add. So I wanna get a_fk and pass it to another context (changelist_view specifically). But the nearest thing I get is self.model.a_fk

[RompePC]

Ok, looks like just adding a ModelForm and getting that field does the work. Sorry for the noobish time.
