Let's say we have custom field that extends CharField, which holds comma-
separated values. Then, let's say we've made a custom widget that
overrides CheckboxMultipleSelect, and takes the field's choices and
combines them into comma-separated values, and we want to use that in the
admin:
{{{#!python
class MyModel(models.Model):
foo = models.MyCustomField(choices=(('FOO', 'Foo'),('BAR',
'Bar')))
class MyAdmin(admin.ModelAdmin):
formfield_overrides = {
MyCustomField: MyCustomWidget
}
}}}
In ModelAdmin, the formfield_for_dbfield will normally check
formfield_overrides to see if there are any overrides. That is, unless,
the field has choices. If the field has choices,
formfield_for_choice_field is called, and formfield_overrides is ignored
completely.
I know that there are other ways of overriding form fields, but it seems
that ModelAdmin.formfield_overrides does not work as advertised.
