Django-admin，按字段选择

Question

There is a UserTask module in which there are very heavy fields and they break the request, how can I remove them from the query for Django Admin.

They do not appear on the page, but Django uses something like this:

SELECT * FROM UserTask;

And you need:

SELECT id, name, is_user FROM UserTask;

It is necessary to remove them in the admin area, here is the registration of the model:

class UserTaskAdmin(admin.ModelAdmin):
    list_filter = ('id', 'name')
    list_display = ('id', 'name')    


admin.site.register(UserTask, UserTaskAdmin)

original version is russian .

You can override get_queryset and use only method:

class UserTaskAdmin(admin.ModelAdmin):
    list_filter = ('id', 'name')
    list_display = ('id', 'name') 

    def get_queryset(self, request):
        return UserTask.objects.only('id', 'name')
