Make a django readonly field visible on the admin

I'm developing a Django project in which I want to allow users to edit a specific field only on add_view. So I've overridden the change_view method on the admin.py so it can set my readonly_fields there. However Django won't display readonly_fields.

It seems really wird for me that a readonly field is not displayed. I mean, if it's readonly, where is the part of it where it says read? It should be readable (only), and not ediable. If I wanted to hide it, there should be an option called hidden_fields or something. Don't you guys agree?

I wonder if is there any straighforward way of make readonly_fields visible on my admin, but not ediable.

my admin.py looks like this:

from django.contrib import admin from core.models import Box

class BoxAdmin(admin.ModelAdmin):
    def change_view(self, request, object_id, form_url='', extra_context=None):
        self.readonly_fields = ('colour',)
        return super(BoxAdmin, self).change_view(request, object_id)

    def add_view(self, request, form_url='', extra_context=None):
        self.readonly_fields = []
        return super(BoxAdmin, self).add_view(request, extra_context=c)

I figured out the problem and it happens to be with my lack of attention. Actually Django does display readonly_fields but I couldn't see it because they are displayed on the bottom of the form. When you don't set the ModelForm.fields attribute they go to the bottom, which was pretty much my case.

Instead of setting self.readonly_fields, you should override get_readonly_fields.

def get_readonly_fields(request, obj=None):
    if obj is None:  # add form
        return []
    else:
        return ['colour']
