Django Admin linking to related objects

Question

My app has users who create pages. In the Page screen of the admin, I'd like to list the User who created the page, and in that list, I'd like the username to have a link that goes to the user page in admin (not the Page).

class PageAdmin(admin.ModelAdmin):
    list_display = ('name', 'user', )
    list_display_links = ('name','user',)
admin.site.register(Page, PageAdmin)

I was hoping that by making it a link in the list_display it would default to link to the actual user object, but it still goes to Page.

I'm sure I'm missing something simple here.

Answer 1

Add this to your model:

  def user_link(self):
      return '<a href="%s">%s</a>' % (reverse("admin:auth_user_change", args=(self.user.id,)) , escape(self.user))

  user_link.allow_tags = True
  user_link.short_description = "User" 

You might also need to add the following to the top of models.py:

  from django.template.defaultfilters import escape
  from django.core.urls import reverse

In admin.py, in list_display, add user_link:

list_display = ('name', 'user_link', )

No need for list_display_links.
