In order to make a model admin read only I suggest you make sure `
get_readonly_fields()
<https://docs.djangoproject.com/en/1.7/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_readonly_fields>`
return all of them.
from django.contrib.admin.utils import flatten_fieldsets
def get_readonly_fields(request, obj=None):
# Put your business logic here to determine whether or not
# the whole model should be read-only based on request.user
# and obj.
return flatten_fieldsets(self.get_fieldsets(request, obj))
