Description
The first InlineModelAdmin displayed in a ModelAdmin subclass does not show the "Add Another" link.
The admin HTML code that gets generated for inlines appears to be inconsistent (for example, the generated HTML has id="id_MAX_FORMS"
while the inlines jQuery is looking for #id_-MAX_FORMS
).

I got your results with the code above and realized I needed to provide more information about my models.
If you set up the ForeignKeys with related_name='+', then you get the behavior I described:
from django.db import models class Author(models.Model): name = models.CharField(max_length=100) class Subject(models.Model): name = models.CharField(max_length=100) author = models.ForeignKey(Author, related_name='+') class Book(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey(Author, related_name='+')

Verified. Note that related_name
actually should be on the FKs, not the CharFields ;-) Thanks for the report!

My god, I am a mess. You're right, it should be on the ForeignKeys.
I need some damn sleep. :P

Tests to pass for admin inlines with related_name='+'

What's occurring here is that related_name='+' causes the form prefix to be blank. This causes issues for inlines because the first item comes through with an entirely blank prefix. This behavior breaks the admin Javascript.
The attached patch passes the regression tests, as best I can tell.
Using the following models.py and admin.py on trunk Django, I get "add another" links for both book and subject when I add/edit an author.
