I have a django admin interface and in the model listing I want a custom column that will be a hyperlink using one of the fields values. Basically one of the models' fields is a url and i'd like the column to have that URL in a clickable hyperlink. This link will need to have additional URL prepended to it as its a relative path in the model field.

A:
Define a method in your ModelAdmin-class and set its allow_tags attribute to True. This will allow the method to return unescaped HTML for display in the column.
Then list it as an entry in the ModelAdmin.list_display attribute.
Example:
class YourModelAdmin(admin.ModelAdmin):
list_display = ('my_url_field',)
def my_url_field(self, obj):
return '<a href="%s%s">%s</a>' % ('http://url-to-prepend.com/', obj.url_field, obj.url_field)
my_url_field.allow_tags = True
my_url_field.short_description = 'Column description'
Se the documentation for ModelAdmin.list_display for more details.

I found out the other day that you actually don't need the `a` tag, since Django admin will automatically turn the URL into a hyperlink. I'm not at my work PC though, so I could be wrong. In my case, I didn't need to set `allow_tags`. I also created a `get_url()` function on my model, as opposed to my admin model - but that's fairly trivial. However, your way is best if we want to open the link in a new window with `target=_blank` -- Hope this is helpful.
