Question

I see this pattern used very often!

• Click on a link
• popup appears with a form
• fill in form and submit
• popup closes and main page populates itself with the form’s data.

---

Any idea how this works?

Edit:

by popup I mean an actual window popup, rather than a modal window. A modal window could work nicely though I reckon.

The only way to do this is with Javascript. Django’s own admin includes a (fairly clunky) example: when you save the popup, it returns a response consisting of just a <script> tag containing Javascript which references the box in the parent form. See for example django.contrib.admin.options.ModelAdmin.response_add.
