如何在django模板中读取对象的"；id "；字段

Posted 2021-02-23

It's imposible to read de "_id" field en django templates ( {{element._id}} === error) So, to read it, you must do a templatetag.

Now you hace the templatetag, you can use it like this: {{element|pk}}

@register.filter(name='pk')
def pk(value):
    if type(value) == type({}):
        if value.has_key('_id'):
            value = value['_id']
    return unicode(value)
