Readonly fields in the django admin/inline

I use this snippet to show several fields in my admin backend as readonly, but as noticed in the comments, it does not work on stackedinline/tabularinline. Is there any other way to achieve this? I have a list of objects attached to a model and just want to show it in the model's details view without the possibility to change values.

As is the case with JQuery, it seems you can achieve this by changing an attr called "disabled" (works in my Safari, OK we're now in 2013 :-) ). Example below:

def get_form(self, request, obj=None, **kwargs):
        result = super(<your ModelAdmin class here>, self).get_form(request, obj=obj, **kwargs)
        result.base_fields[<the select field you want to disable>].widget.attrs['disabled'] = 'disabled'
        return result

If you are running Django 1.3 or later; there's an attribute named ModelAdmin.readonly_fields which you could use.

InlineModelAdmin inherits from ModelAdmin, so you should be able to use it from your inline subclass.

I've encountered the same problem today. Here is my solution. This is example of read-only field for the ForeignKey value:

class MySelect(forms.Select):
    def render(self, name, value, attrs=None, choices=()):
        s = Site.objects.get(id=value)
        return s.name

class UserProfileInlineForm(forms.ModelForm):
    site = forms.ModelChoiceField(queryset=Site.objects.all(), widget=MySelect)

class UserProfileInline(admin.StackedInline):
    model = UserProfile
    form = UserProfileInlineForm
