    <p>I'm new to rails and am having challenges adding a commenting system to my listings model. Effectively I have listings that are created by users, and I want the ability to allow other users to make comments on these listings. </p> <p>What I have so far:</p> <p>A listing model that includes:</p> <pre><code>has_many :comments </code></pre> <p>a comment model that includes:</p> <pre><code>belongs_to :listing </code></pre> <p>a comments controller:</p> <pre><code>class CommentsController &lt; ApplicationController def create @listing = Listing.find(params[:listing_id]) @comment = @listing.comments.build(params[:body]) # ***I suspected that I needed to pass :comment as the params, but this throws an error. I can only get it to pass with :body *** respond_to do |format| if @comment.save format.html { redirect_to @listing, notice: "Comment was successfully created" } format.json { render json: @listing, status: :created, location: @comment } else format.html { render action: "new" } format.json { render json: @comment.errors, status: :unprocessable_entity } end end end end def comment_params params.require(:comment).permit(:body, :listing_id) end </code></pre> <p>and finally a listing view that includes the following code to collect and display comments:</p> <pre><code> &lt;div class="form-group"&gt; &lt;%= form_for [@listing, Comment.new] do |f| %&gt; &lt;%= f.label :comments %&gt; &lt;%= f.text_area :body, :placeholder =&gt; "Tell us what you think", class: "form-control", :rows =&gt; "3" %&gt; &lt;p&gt;&lt;%= f.submit "Add comment", class: "btn btn-primary" %&gt;&lt;/p&gt; &lt;% end %&gt; &lt;/div&gt; &lt;%= simple_form_for [@listing, Comment.new] do |f| %&gt; &lt;p&gt; &lt;%= f.input :body, :label =&gt; "New comment", as: :text, input_html: { rows: "3" } %&gt; &lt;/p&gt; &lt;p&gt;&lt;%= f.submit "Add comment", class: "btn btn-primary" %&gt;&lt;/p&gt; &lt;% end %&gt; </code></pre> <p>The comment box is displaying correctly in the view, and I'm able to submit comments, however it appears that the :body isn't being saved, and therefore the "submitted x minutes ago" is the only thing that's showing up in my comments section.</p> <p>Any ideas on what I could be doing incorrectly? I suspect it's a params issue, but haven't been able to work it out.</p> <p>Thanks!</p>

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.
