Where is Ruby being told to display this information?

Question

Brief question, beginner's work on Ruby/Rails. Here's my view:

<h1>News</h1>


<%= @posts.each do |post| %>

<h1><%= post.title %></h1>

<p><strong>By:</strong> <%= post.name %></p>

<p><%= post.content %></p>

<p><%= link_to 'Read More', post %> | <%= link_to 'Edit', edit_post_path(post) %> | <%= link_to 'Destroy', post, :confirm => 'Are you sure you want to delete this post?', :method => :delete %></p>

<p>hello!</p>

<% end %>

<br />



<%= link_to 'New Post', new_post_path %>

I put the <p>hello<p> in there so I could see where the output was coming from, but here's what the page looks like...

That last dump, which looks like XML or a JSON object, following the loop, is not being told to print anywhere in the view...I don't understand where it's coming from, what it's called, or how to get rid of it. Help?

Answer 1

Wild guess: change <%= @posts.each do |post| %> to <% @posts.each do |post| %> (notice lack of = sign).

<% .. %> in erb template means "execute this".
<%= .. %> in erb template means "execute this and print output on the page".

@posts.each is a loop. It's used to iterate over @posts collection. And even though each method returns some data (collection itself), there's no need to print that data.
