why isn't my id showing up in django admin list?

I have a class Task(models.Model), and i didn't define id field explicitly (since it defines automatically for you). I checked in the database, it exists for the Task. Now i would like to display it in the list via list_display property in admin.ModelAdmin. I have a bunch of things in there, only id is not showing up for any of the rows i have. Everything else works fine. Anyone know anything special i have to do to get id to display?

EDIT: if i define a function as follows:

def ID(self, obj):
        return obj.id

and i put this function in list_display, it will displ开发者_运维问答ay id just fine for some reason.

Thanks a lot!

It doesn't show by default. You need to create a custom Admin class for that model and then add 'id' to the list_display value. E.g. in whatever/admin.py:

class TaskAdmin(admin.ModelAdmin):
    list_display = ['id', 'name', etc. etc] 

admin.site.register(Task, TaskAdmin)

See the docs for more details.

I believe you have also used list_editable in your admin.ModelAdmin. This causes the ID to be hidden and is a known bug: http://code.djangoproject.com/ticket/12475.

The work around is to state list_display_links option:

class AdAdmin(admin.ModelAdmin):
    list_display = ['id', 'ad_title', 'status', 'sponsor' ... ]
    list_display_links = ['id', 'ad_title'] # forcing to display id of model
    list_editable = ['status']
    ...

Thanks and hope this helps.
