我必须为json请求和json响应创建这个RESTful api。 当我使用这个RESTful api for Android应用程序时,我了解到我登录并从RESTful api获取Token,然后该Token用于通过Header将数据发布到RESTful api。
作为邮差捕获,
我必须填写"作者":"编号"在身体上。我认为这个数字意味着用户在我的RESTful api上注册了订单。从上面捕获,该作者是我的RESTful api的第一个用户。
如果我将作者字段设为空,则返回
{
"author": [
"This field is required."
]
}
我如何填写"作者"部分自动使用令牌(或其他方式不使用令牌)?
如何获取json响应"author":"some alphabet name readable"
,而不是"author":"1 or 2 like number"
作为捕获。我希望表格像"author":"stackoverflowman"
。
答案 0 :(得分:2)
对于您的第一个问题,您应该添加PostViewSet
此功能:
def perform_create(self, serializer):
serializer.save(author=self.request.user)
对于您的第二个问题,您应该从UserSerializer
致电PostSerializer
:
class PostSerializer(serializers.ModelSerializer):
author = UserSerializer(read_only=True)
class Meta:
model = Post
fields = ('id', 'created_date', 'author', 'text', 'image')
修改强>
如果您只想要一个字段,则可以使用source声明一个字段:
class PostSerializer(serializers.ModelSerializer):
author = serializers.ReadOnlyField(source='author.username')
class Meta:
model = Post
fields = ('id', 'created_date', 'author', 'text', 'image')
