    copied!<p>So my initial question was <a href="https://stackoverflow.com/questions/11572293/association-ruby-on-rails">Association Ruby on Rails</a>. However when referring to a post the issue that i am having is that its blank. Don't see anything. After researching I believe is because when i created my test post I didn't define a customer related to it.</p> <pre><code>class CustomersController &lt; ApplicationController before_filter :signed_in_customer, only: [:edit, :update] before_filter :correct_customer, only: [:edit, :update] def index @customers = Customer.all end def show @customer = Customer.find(params[:id]) **@posts = @customer.posts** end </code></pre> <p>Here the form that allow me to create a post for the moment.</p> <pre><code>&lt;%= form_for(@post) do |f| %&gt; &lt;% if @post.errors.any? %&gt; &lt;div id="error_explanation"&gt; &lt;h2&gt;&lt;%= pluralize(@post.errors.count, "error") %&gt; prohibited this post from being saved:&lt;/h2&gt; &lt;ul&gt; &lt;% @post.errors.full_messages.each do |msg| %&gt; &lt;li&gt;&lt;%= msg %&gt;&lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;/div&gt; &lt;% end %&gt; &lt;div class="field"&gt; &lt;%= f.label :title %&gt;&lt;br /&gt; &lt;%= f.text_field :title %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :description %&gt;&lt;br /&gt; &lt;%= f.text_field :description %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :frienship_group_id %&gt;&lt;br /&gt; &lt;%= f.text_field :frienship_group_id %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :post_size_id %&gt;&lt;br /&gt; &lt;%= f.text_field :post_size_id %&gt; &lt;/div&gt; &lt;div class="actions"&gt; &lt;%= f.submit %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>Which is what i am using when creating a new form. How i am suppose to allow customization to update the field that this is related to the current user in the customer_id field?</p> <p>Here the model </p> <pre><code> class Post &lt; ActiveRecord::Base belongs_to :customer validates :title, presence: true validates :description, presence: true validates :customer_id, presence: true validates :frienship_group_id, presence: true validates :Post_size_id, presence: true </code></pre> <p>Update: </p> <p>Here my new.html.erb for post</p> <pre><code>&lt;h1&gt;New post&lt;/h1&gt; &lt;%= render 'form' %&gt; &lt;%= link_to 'Back', posts_path %&gt; </code></pre> <p>Here the controller</p> <pre><code>class PostsController &lt; ApplicationController # 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]) 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>
