Question

My index action in my controller is something like this:

@dbs = somearray

My view corresponding to this action (index.html.erb) is trying to print only the elements of the @dbs array but it prints no only the elements individually but the entire array as well (which I want to avoid printing). The code printing in index.html.erb is:

<%= for db in @dbs do %>
  <tr>
    <td><%= db %></td>
  </tr>
<% end %>

This prints:

["ele1","ele2","ele3"]
----
ele1
----
ele2
----
ele3
----

How can I avoid printing: ["ele1","ele2","ele3"]? I just want to print the table with the elements!

Answer 1

The construction <%= %> is printing into output, <% %> doesn’t print into output. Just change one line to this:

<% for db in @dbs do %>
