    <p>I'm creating my own blog on Rails with posts and users. I need to show all posts from specific author when I click on him (here the concept:<a href="http://i.imgur.com/RqUDwZj.png">link</a>). What should I do for this? Please say what extra information or code should I add</p> <p>users_controller:</p> <pre><code>class UsersController &lt; ApplicationController def show @user = User.find(params[:id]) @posts = @user.posts end end </code></pre> <p>posts_controller:</p> <pre><code>class PostsController &lt; ApplicationController before_filter :authenticate_user!, :except =&gt; [:show, :index] # GET /posts # GET /posts.json def index @posts = Post.all respond_to do |format| format.html # index.html.erb format.json { render json: @posts } end end # GET /posts/1 # GET /posts/1.json def show @post = Post.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json { render json: @post } end end # GET /posts/new # GET /posts/new.json def new @post = Post.new respond_to do |format| format.html # new.html.erb format.json { render json: @post } end end # GET /posts/1/edit def edit @post = Post.find(params[:id]) end # POST /posts # POST /posts.json def create #@post = Post.new(params[:post]) @post = current_user.posts.build(params[:post]) respond_to do |format| if @post.save format.html { redirect_to @post, notice: 'Post was successfully created.' } format.json { render json: @post, status: :created, location: @post } else format.html { render action: "new" } format.json { render json: @post.errors, status: :unprocessable_entity } end end end # PUT /posts/1 # PUT /posts/1.json def update @post = Post.find(params[:id]) respond_to do |format| if @post.update_attributes(params[:post]) format.html { redirect_to @post, notice: 'Post was successfully updated.' } format.json { head :no_content } else format.html { render action: "edit" } format.json { render json: @post.errors, status: :unprocessable_entity } end end end # DELETE /posts/1 # DELETE /posts/1.json def destroy @post = Post.find(params[:id]) @post.destroy respond_to do |format| format.html { redirect_to posts_url } format.json { head :no_content } end end end </code></pre> <p>user model:</p> <pre><code>class User &lt; ActiveRecord::Base # Include default devise modules.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
