Support for different field names

[johnwoltman]

The interface doesn't work when the ContentType-related fields aren't object_id. Is there a way to integrate genericadmin into an existing a codebase? For my model, I've been using target_id as the field for storing IDs of other objects in my ContentType-enabled models.

Dear All,
I have the same question.

Mine are:
layer_content_type = models.ForeignKey(ContentType)
layer_id = models.PositiveIntegerField()
layer = generic.GenericForeignKey('layer_content_type', 'layer_id')

And in the admin this won't work:

class MyAdminClassGenericAdminModelAdmin):
****
ct_field = 'layer_content_type'
ct_fk_field = 'layer_id'

ideas?

I think (it's been some time since I last looked at this) that the field id is hardcoded in the javascript and the trouble with making this more flexible is that exchanging data between Django and javascript files sucks quite a bit.

So, I hope I can take a look at this a bit more tomorrow but if you want to try yourself and just need something that works, try to change the javascript file so that it finds the right field.

Thanks for replying and point me.
Django-genericadmin is the best that Internet is offering to manage ContentType in Django!
It took me 3 minutes and it was working. Thank you!
I'm going to look at the JS and I will report to you tomorrow!

Took a little longer then expected, but the newest version will a) figure out all generic foreign keys on the model by itself (yes, it does work with multiple generic fks) and b) also work with all names provided.

If you want to configure manually which fields the javascript will handle, you can set the generic_fk_fields option on the admin. It should take the form:

class MyAdmin(GenericAdminModelAdmin):
    generic_fk_fields = [{
        'ct_field': <field_name_for_contenttype_fk>,
        'fk_field': <field_name_for_object_id>,
    }]

For more then one GenericForeignKey add one more dict to the list.

I'm not sure if this interferes with the inline admin options.

So, as far as I can tell version 0.5 (yay, it's even on Pypi) works with an unlimited number of generic fields and completely supports inline admins.

If you find problems, I'd appreciate reopening this issue or a new issue.
