I would like to be able to render multiple Json renders in my controller. I have a rails Json API using the Model serializers gem. At the moment I can only render one object. What I would like to do is to also render the @news and @users but right now I'm only rendering the @articles.
Backend Articles controller.rb:
class ArticlesController < ApplicationController
impressionist :actions=>[:show]
# GET /articles
# GET /articles.json
def index
@articles = Article.where(:is_published => true).order('created_at DESC').page(params[:page]).per(6)
@news = Article.where(:news => true)
@users = User.all
respond_to do |format|
format.html # show.html.erb
format.json { render json: @articles.all }
end
end
end
Backend Article Serializer:
class ArticleSerializer < ActiveModel::Serializer
attributes :id, :title, :teaser_title, :content, :teaser_content, :category, :author, :published, :num_comments, :tags, :featured, :app, :news, :tech, :device, :game, :laptop, :image, :user_id, :is_published, :created_at, :updated_at, :impressionist_count, :previous_post, :next_post, :user_id
end
Frontend site Article Model:
require 'active_resource'
class Article < ActiveResource::Base
self.site = "http://localhost:3000"
end
Frontend Site Articles Controller:
class ArticlesController < ApplicationController
def index
@articles = Article.where(:is_published => true)
@news = Article.where(:is_published => true, :news => true)
@users = User.all
end
end
Frontend site Article index.html.erb:
<div id='outer-wrapper'>

For some reason the definitions which I have set don't seem to have any affect because no matter what the @news is the same at @articles even though I have set what I want specifically using where.
What I understand is that you want to return a multipart JSON containing more than 1 type of resources, articles, news and users in your case. And if I understand it right, here's a piece of code which might help you.
Let's say you have a controller called manage_content.rb, write a function inside it.
def return_content
@articles = Article.where(:is_published => true).order('created_at DESC').page(params[:page]).per(6)
@news = Article.where(:news => true)
@users = User.all
# This is will create a single object with embedded arrays of your resource objects inside.
@content = {
articles: @articles,
news: @news,
users: @users
}
render json: { :data => @content, :status => 200 }
end
And in your config/routes.rb, add the corresponding route
get 'render_content' => "manage_content#return_content"
Test it by firing localhost:3000/render_content from your broswer. This should render you a JSON like,
{
data:
{
articles: [
{.....},
{.....}
],
news: [
{.....},
{.....}
],
users: [
{.....},
{.....}
]
},
status: 200
}
Remember that articles, users and news are JSON arrays. Mind the arrays and objects while parsing the json response at your front-end.
Regards.
