Django ModelForm with Select Widget - Use object.uid as default option value instead of object.id

Question

I have a form inheriting from ModelForm as such: ``` class ChildModel(ModelForm): class Meta: model = Documents fields = ('secretdocs') widgets = { 'secretdocs': Select(attrs={'class': 'select'}), } ``` The model "secretdocs" has a uid. But when it prints out the select and option, the option values appear as such: ``` ``` But I want it to instead have the uid of the option: ``` ``` I've so far tried to use BaseForm's data object and overwriting Select's value_from_datadict method but I'm pretty sure that wasn't the right approach. Does anyone know how I can do this? Thanks in advance.

Accepted Answer

You can do something like this:

```
class ChildModel(ModelForm):

secretdocs = forms.ChoiceField(choices=[(doc.uid, doc.name) for doc in Document.objects.all()])
  class Meta:
      model = Documents
      fields = ('secretdocs', )
      widgets = {
          'secretdocs': Select(attrs={'class': 'select'}),
      }
```
