Is there a way to have a field that only the superuser can add/edit?

Question

Is there a way to have a field that only the superuser can add/edit?

class ProductPage(Page):
    price = models.IntegerField(blank=True)
    description = RichTextField(blank=True)
    featured = models.BooleanField(default=False)

Above is part of my model but i only want the superuser to access the featured field.

Answer 1

I'm assuming you mean that only superusers logged in the Django admin site should be able to edit the featured field. If you want to restrict access in your own forms and views, you just need to check the user's status and customize the form/view accordingly. Here's what you can do in admin.py, in your ModelAdmin:

def get_readonly_fields(self, request):
    fields = super().get_readonly_fields(request)
    if not request.user.is_superuser:
        fields.append('featured')
    return fields

Answer 2

I tried out the solution given by @dirkgroten but had to make a few changes to make it work.

According to the Django Documentation for >2.1 versions of Django, the get_readonly_fields take 3 parameters.

Also, fields need to set a list to append, as it creates a tuple on default.

def get_readonly_fields(self, request, obj=None):
    fields = list(super().get_readonly_fields(request))
    if not request.user.is_superuser:
        fields.append('featured')
    return fields
