Re: Admin Change List: Display Foreign Keys as Links to Related Change Form

This solution did not work out of the box but it helped me figure out
a simple but tedious solution:

In models.py:
-----------------
class AppParent(models.Model):
...
def get_url(self):
return
urlresolvers.reverse('admin:myapp_appparent_change',args=(self.id,))

class AppChild
app_parent = models.ForeignKey(AppParent)
...
def edit_parent(self):
return mark_safe(u'<a href="%s">%s</a>' %
(self.app_parent.get_url(),self.app_parent))

Then in admin.py:
----------------------
from manager.models import AppChild
class AppChildAdmin(admin.ModelAdmin):
list_display = ('id','edit_parent',...)

The case is very important above. reverse() requires the model_name
parameter to be the parent model class name converted to all lower
case, with no underscores between words. That took a lot of
experimentation to figure out. Where is that documented?

This whole hack should not be needed: any database web GUI should
automatically display foreign keys as hyperlinks to allow drilling
into parent records. Is this being added to Django Admin Change List I
hope?

Any ideas on how to genericize this solution so I don't have to update
every model/change_list to display foreign keys as hyperlinks?

Thanks for all help.
