如何获取一个外键字段的模型出现在Django-Serializer中？ [英] How to get a field of a foreign key Model appear in a Django-Serializer?

问题描述

我正在构建一个公开一个REST API的Django应用程序，用户可以通过该API访问我的应用程序模型2。我遵循 这里 的说明。

我的两个模型是：

1. 来自django.contrib的Django用户模型.auth



2. 模型如下所示。

    模型）：
    user = models.OneToOneField（User）
     

我的串行程序如下：

  class UserSerializer（serializers.HyperlinkedModelSerializer）：
 class Meta ：
 model = User 
 fields =（'url'，'username'，'email'）
 
 class ProfileSerializer（serializers.HyperlinkedModelSerializer）：
 class Meta ：
 model = Profile 
 fields =（'id'，'slug'，'user'，）
  

我可以看到，当我从命令行点击API时，这是正常工作：

 ％curl -H'Accept：application / json; indent = 4'-u root：MyPassword http://127.0.0.1:3001/api/profiles/60/ 
 {
id：60，
slug：myprofile ，
user：http://127.0.0.1:3001/api/users/16/
} 
 
％curl -H'Accept：application / JSON; indent = 4'-uroot：MyPassword http://127.0.0.1:3001/api/users/16/ 
 {
url：http://127.0.0.1:3001/api/用户/ 16 /，
username：myUser，
email：[e-mail]
} 
  / pre> 
 
 
我想知道的是两件事：
 
 
 
 
 
如何公开这个API，即使没有root / password登录，也可以使用该用户的用户名？
 
 
 
 
解决方案
问题＃1正确回答：如何在外键的查询详细信息字段中包含（ django和rest_api） 
 
 
 
问题＃2在这里重新询问：如何管理访问Django REST API的权限？ 
 
I am building a Django application that exposes a REST API by which users can query 2 of my application's models. I'm following the instructions here.

My two models are:

The Django User model from django.contrib.auth
The model shown below.
class Profile(models.Model):  
    user = models.OneToOneField(User)

My Serialiazers are as follows:
class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'email', )

class ProfileSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Profile
        fields = ('id', 'slug', 'user',)
I can see that this is working when I hit the APIs from the command-line:
% curl -H 'Accept: application/json; indent=4' -u root:MyPassword http://127.0.0.1:3001/api/profiles/60/
{
    "id": 60,
    "slug": "myprofile",
    "user": "http://127.0.0.1:3001/api/users/16/"
}

% curl -H 'Accept: application/json; indent=4' -uroot:MyPassword http://127.0.0.1:3001/api/users/16/
{
    "url": "http://127.0.0.1:3001/api/users/16/",
    "username": "myUser",
    "email": "[e-mail]"
}
What I would like to know are two things:

How do I change my Profile's serializer such that the user's username appears in the serialized profile?
How can I expose this API publicly so it works even without the root/password login?

解决方案
Question #1 Answered correctly here: How to include in queryset details fields of a foreign key (django and rest_api)

Question #2 Re-asked more clearly here: How are permissions to access to Django REST API managed?
