Readonly models in Django admin interface?

Question

How can I make a model completely read-only in the admin interface? It\'s for a kind of log table, where I\'m using the admin features to search, sort, filter etc, but there

Answer 1

Here are two classes I am using to make a model and/or it's inlines read only.

For model admin:

from django.contrib import admin

class ReadOnlyAdmin(admin.ModelAdmin):
    readonly_fields = []

    def get_readonly_fields(self, request, obj=None):
        return list(self.readonly_fields) + \
               [field.name for field in obj._meta.fields] + \
               [field.name for field in obj._meta.many_to_many]


    def has_add_permission(self, request):
        return False

    def has_delete_permission(self, request, obj=None):
        return False

class MyModelAdmin(ReadOnlyAdmin):
    pass

For inlines:

class ReadOnlyTabularInline(admin.TabularInline):
    extra = 0
    can_delete = False
    editable_fields = []
    readonly_fields = []
    exclude = []

    def get_readonly_fields(self, request, obj=None):
        return list(self.readonly_fields) + \
               [field.name for field in self.model._meta.fields
                if field.name not in self.editable_fields and
                   field.name not in self.exclude]

    def has_add_permission(self, request):
        return False


class MyInline(ReadOnlyTabularInline):
    pass
