9561	ForeignKeyRawIdWidget turns string into comma-separated chars in lookup URL	andyhd	nobody	"Using a ForeignKey with limit_choices_to a filter that matches a string:
{{{
class Foo(models.Model):
    bar = models.ForeignKey('Bar', limit_choices_to={'blarch': 'quux'})
#                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
class Bar(models.Model):
    blarch = models.CharField(max_length=20)
}}}

And a custom admin with raw_id_fields:
{{{
class FooAdmin(admin.ModelAdmin):
    raw_id_fields = ('bar',)
}}}

results in the changeform magnifying glass lookup link having a URL like this:
""../../../fail/blarch/?'''blarch=q,u,u,x'''""

Fixed by placing the single string value in a list (see patch)"		closed	contrib.admin	1.0		fixed	ForeignKeyRawIdWidget limit_choices_to		Unreviewed	1	0	0	0	0	0
