UserMailer erroring on <% end %> within an <% end %> why is that?

I have a UserMailer template that is text. Inside the text view I have the following:

<% if !@thing.empty? %>
  <% @thing.each do |id, count| %>
    <%= #{count}%> <%= #{id} %> 
  <% end %>
<% end %>

This seems fine but it errors with?

ActionView::Template::Error: /app/views/user_mailer/user_daily_activity.text.erb:12: unterminated string meets end of file
/app/views/user_mailer/myfile.text.erb:12: syntax error, unexpected $end, expecting ')'

Why is Rails erroring on this?

Solution

  • The #{count} format is only for use within strings, not as a standalone reference. Since you're not using it in a string, the # is interpreted as a comment.

    Try this instead:

    <%= count %> <%= id %>

    This would also be equivalent:

    <%= "#{count} #{id}" %>
