python - Django api 返回模型 ID 而不是模型的标题

Question

我是 django 的新手 当我调用 api 它显示 model.id 但我想要 model.title

我们可以看到我的标题是 1 但我想要的是模型的标题而不是 ID

模型.py

class Post(models.Model):
    title=models.CharField(max_length=200)
    description=models.TextField(max_length=10000)
    pub_date=models.DateTimeField(auto_now_add=True)


    def __unicode__(self):
        return self.title

    def description_as_list(self):
        return self.description.split('\n')

class Comment(models.Model):
    title=models.ForeignKey(Post)
    comments=models.CharField(max_length=200)

    def __unicode__(self):
        return '%s' % (self.title)

View .py

def detail(request, id):
    posts = Post.objects.get(id=id)
    comments=posts.comment_set.all()
    forms=CommentForm
    if request.method == 'POST':
        form=CommentForm(request.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.title = posts
            print comment
            comment.save()
        else:
          print form.errors
    else:
        form = PostForm()

    return render(request, "detail_post.html", {'forms':forms,'posts': posts,'comments':comments})

序列化器.py

class CommentSerializer(serializers.ModelSerializer):
    class Meta:
        model = Comment
        fields = ('title','comments')

class PostSerializer(serializers.ModelSerializer):
    class Meta:
        model = Post
        fields = ('id','title','description','pub_date')

如何实现博客名称的标题而不仅仅是ID

Answer 1

class CommentSerializer(serializers.ModelSerializer):

    title = serializers.CharField(source="title.title", read_only=True)

    class Meta:
        model = Comment
        fields = ('title','comments')
