python - Django 模板和 MongoDB _id

Question

Variables and attributes may not begin with underscores: 'value._id'

如何在 Django 模板中引用从 MongoDB 获取的项目的 _id？

Answer 1

Custom template filter会有所帮助:

from django import template

register = template.Library()

@register.filter(name='private')
def private(obj, attribute):
    return getattr(obj, attribute)

你可以这样使用它:

{{ value|private:'_id' }}
