PODjango admin: Inline of a Many2Many model with 2 foreign keys
text
Body
copied!<p>after wracking my brain for days, I just hope someone can point me to the right approach. I have 4 Models: Page, Element, Style and Post.</p> <p>Here is my simplyfied models.py/admin.py excerpt: <a href="http://pastebin.com/uSHrG0p2" rel="nofollow">http://pastebin.com/uSHrG0p2</a></p> <p>In 2 sentences:</p> <p>A Element references 1 Style and 1 Post (2 FKs).</p> <p>A Page can reference many Elements, Elements can be referenced by many pages (M2M).</p> <p>On the admin site for Page instances I included the M2M relation as 'inline'. So that I have multiple rows to select Element-instances. One row looking like: [My Post A with My Style X][V]</p> <p>What I want is to replace that one dropdown with 2 dropdowns. One with all instances of Post and one with all instances of Style (creating Element instances in-place). So that one row would look similar to the Element admin site: [My Post A][V] [My Style X][V]</p> <p>Sounds easy, but I'm just completely lost after reading and experimenting for 2 days with ModelForms, ModelAdmins, Formsets, ... . Can I do that without custom views/forms within the Django admin functionality?</p> <p>One of my approaches was to access the Post/Style instances from a PageAdminForm like this, trying to create a form widget manually from it... but failed to do so:</p> <pre><code>p = Page.objects.get(pk=1) f = PageAdminForm(instance=p) f.base_fields['elements'].choices.queryset[0].post </code></pre> <p>Any advice or hint which way I need to go? Thank you for your time!</p>
