以json格式获取包含所有评论的所有帖子(Get all posts with all comments in json format)

我有两个模型Post和Comment

class Post < ActiveRecord::Base has_many :comments end class Comment < ActiveRecord::Base belongs_to :post end

如何获得所有带有评论的帖子，如下面的json响应：

{ "posts": [ { "name": "Ruby on Rails", "comments": [ { "desc": "awesome" } ] }, { "name": "Java", "comments": [ { "desc": "Thanks" }, { "desc": "very useful" } ] } ] }

I have two models Post and Comment

class Post < ActiveRecord::Base has_many :comments end class Comment < ActiveRecord::Base belongs_to :post end

How can I get all the posts with comments as below json response:

{ "posts": [ { "name": "Ruby on Rails", "comments": [ { "desc": "awesome" } ] }, { "name": "Java", "comments": [ { "desc": "Thanks" }, { "desc": "very useful" } ] } ] }

最满意答案

试试这个，在app / views / posts /中创建一个index.json.jbuilder，并添加以下代码

json.posts @posts do |post| json.name post.name json.comments post.comments do |comment| json.desc comment.desc end end

try this, create a index.json.jbuilder in app/views/posts/ , and add the following code to it

json.posts @posts do |post| json.name post.name json.comments post.comments do |comment| json.desc comment.desc end end
