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

Compiling @darklow and @josir 's excellent answers, plus adding a bit more to remove "Save" and "Save and Continue" buttons leads to (in Python 3 syntax):

class ReadOnlyAdmin(admin.ModelAdmin):
    """Provides a read-only view of a model in Django admin."""
    readonly_fields = []

    def change_view(self, request, object_id, extra_context=None):
        """ customize add/edit form to remove save / save and continue """
        extra_context = extra_context or {}
        extra_context['show_save_and_continue'] = False
        extra_context['show_save'] = False
        return super().change_view(request, object_id, extra_context=extra_context)

    def get_actions(self, request):
        actions = super().get_actions(request)
        if 'delete_selected' in actions:
            del actions['delete_selected']
        return actions

    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

and then you use like

class MyModelAdmin(ReadOnlyAdmin):
    pass

I've only tried this with Django 1.11 / Python 3.
