TagSelectField (using FilteredSelectMultiple)

[GoogleCodeExporter]

A variation of the django-tagging TagField which uses a 
SelectMultiple widget instead of free text field. (Actually, it uses
admin's FilterSelectMultiple).

class MyModel(models.Model):
    ...
    tags = TagSelectField(filter_horizontal=True, blank=False)

Sometimes we only want users to select from existing tags, rather than
create new ones on the fly. But at the same time we want all the
django-tagging features (multiple content types, the funky managers, etc),
so don't want to go back to a plain old ManyToMany.

Ideally, this and TagField shouldn't really need a database column. But it
seems Django's model fields must either be a 'field', which needs a
database field; or a 'many to many', which needs a related table. Patching
a many to many field works for instance add/update but the instance delete
method is hard coded to expect the related table.

I think this might be worth including in tagging.fields.

I agree. We don't expect to allow user tagging on our site (not a blog), but 
entries
tagged by us would be very useful. And FilterSelectMultiple is the proper 
interface
for that.

litchfield4:
i modified your TagSelectField to allow for filtered choices. if 'choices' is 
passed as a keyword 2 tuple, only a 
subset of tags are displayed/chosen.

however this has a problem: forms in the admin generated from model fields work 
as expected, but the same 
syntax in admin forms in admin.py throws an error or is ignored. :(

this needs to be added to the project ASAP, it's a great feature and it really 
puzzled 
me that this wasn't the default approach for tagging when i first installed 
django-
tagging.

major thanks
