Simplify add_type_form.html

[BertrandBordage]

Rendering is broken when using django-grappelli:

Simplifying add_type_form.html fixes it. With only this and nothing else:

{% extends "admin/change_form.html" %}

{% block submit_buttons_bottom %}
  {% include 'admin/submit_line.html' with show_save=True %}
{% endblock %}

we get:

It also works perfectly without grappelli:

If this change is OK, I'll make a pull request.

(I also had to extend the context to add add=True)

Yes, please send a pull request. If there is anything else you'll find with grappelli compatibility let me know. I'm ok with those changes as long as the regular Django admin is unaffected by it.

It makes sense to me to add an inline comment that show_save=True is for grappelli, and maybe it would be useful to include those variables in the template context instead but I'll leave that to your expertise on that.

[BertrandBordage]

OK, I'll make a pull request.

show_save=True is not for grappelli only. admin/submit_line.html is the template with all the buttons. Instead of making our own submit button or including all buttons (save and continue, save and add another, save), I just wrote "show only the save button" and that's it. That's the cleanest way to do this IMO.

In the pull request, I'll also handle save_on_top so that buttons are not shown on top AND bottom if the user set it to True.

The pull request has been merged! Sorry for the long delay.

We've also released a new version, django-polymorphic 0.5.1 contains this fix.

Excellent, thanks :)
