我如何将相关的字段包含在django rest框架中的模型序列化中？(How can I include related fields to the model serialization in django rest framework?)

 我有两个模型： 
 
class User(models.Model):
  username = models.CharField()
 
 和 
 
class Post(models.Model):
  text = models.TextField()
  owner = models.ForeignKey(User)
 
 使用这样的序列化器： 
 
from rest_framework.serializers import ModelSerializer

class PostSerializer(ModelSerializer):
    owner = serializers.Field(source='owner.id')

    class Meta:
        model = Post
        fields = ['text', 'owner']
 
 我通过所有者的ID获取所有帖子。 如何修改序列化程序以获取包含所有用户模型的拥有者的所有帖子？ 
 
 我尝试从rest_framework.serializers导入ModelSerializer 
 
class PostSerializer(ModelSerializer):
    owner = serializers.Field(source='owner')

    class Meta:
        model = Post
        fields = ['text', 'owner']
 
 但只是用用户名替换id，而不是我期望的整个模型（因为用户的表示返回用户名字段）。 

I have two models: 
 
class User(models.Model):
  username = models.CharField()
 
and
 
class Post(models.Model):
  text = models.TextField()
  owner = models.ForeignKey(User)
 
Using such serializer:
 
from rest_framework.serializers import ModelSerializer

class PostSerializer(ModelSerializer):
    owner = serializers.Field(source='owner.id')

    class Meta:
        model = Post
        fields = ['text', 'owner']
 
I get all posts with owners' ids. How can I modify serializer to get all posts with owner fialed containing the whole user model?
 
I tryied from rest_framework.serializers import ModelSerializer
 
class PostSerializer(ModelSerializer):
    owner = serializers.Field(source='owner')

    class Meta:
        model = Post
        fields = ['text', 'owner']
 
but that only replaced id with username, not the whole model as I expected(because User's representation returns username field).
