[PATCH] raw_id_admin field has incorrect value in admin form after validation errors

[Christopher Lenz <cmlenz@…>]

I'm not sure what this is all about, I'm I was having the following problem:

In the admin for an object that has a raw_id_admin field, when opening an object for editing, the value of the text input is correct: a comma-separated list of IDs:

  <input type="text" value="1,2,3" ... />

However, when saving the object but getting validation errors, the form field suddenly contains the repr of the equivalent Python list in the value attribute:

  <input type="text" value="[&#39;1&#39;, &#39;2&#39;, &#39;3&#39;]" ... />

I'll attach a patch that fixes this, but I'm really not sure where the actual problem is, and where it should be ideally fixed.

Quick and dirty fix for the problem

How do I replicate this problem? Is it a matter of creating a custom form manipulator and model?

The patch looks correct and I think you are fixing the problem in the right place, don't worry.

Thanks, Christopher Lenz.
