Django ModelForm - Allowing adds for ForeignKey <p>I'm trying to mimic the functionality from the Django Admin tool where it allows you to add objects for foreign keys (a little plus icon next to a dropdown). For example, let's say I have the following:</p> <pre><code>class Author(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) class Blog(models.Model): name = models.CharField(max_length=50) author = models.ForeignKey('Author') </code></pre> <p>When I go to add my first Blog using a ModelForm for Blog, it shows a dropdown next to Author. However, I have no Authors in the system so that dropdown is empty. In the admin tool, I believe it puts a little "+" icon next to the dropdown so you can quickly and efficiently add a record to the dropdown by opening up a popup.</p> <p>That is extremely useful, and so I'd like to mimic it in my own app using ModelForms. Is that also built into Django's ModelForms? If so, how do I use it? I can't seem to find anything in the documentation.</p>
