Rails syntax error, unexpected keyword_ensure, expecting keyword_end - ruby-on-rails

Question

I'm trying to get two different types of tags working using the acts_as_taggable_on gem. I was following this link. I'm getting this error:
syntax error, unexpected keyword_ensure, expecting keyword_end
yntax error, unexpected end-of-input, expecting keyword_end
The error says the problem is line 92 of my show.html.erb, but when I put and <% end %> there, it doesn't fix it.
show.html.erb

and private method that permits
:tag_list, :tag, :series_list, :series
artwork.rb has

acts_as_taggable_on :tags, :series
What am I doing wrong?

Answer 1

You are failing to close 2 of your loops with an <% end %>.
<% unless #artwork.series.blank? %>
<div class="col-xs-6 col-sm-6 col-md-4">
<p class="field-label">Series</p>
<% #artwork.series.each do |series| %>
<span class="tags">
<%= link_to series.name, series_url(:series => series.name) %>
</span>
<%# Need end here, as illustrated on the next line. %>
<% end %>
</div>
<% end %>
<% unless #artwork.tags.blank? %>
<div class="col-xs-6 col-sm-6 col-md-4">
<p class="field-label">Tags</p>
<% #artwork.tags.each do |tag| %>
<span class="tags">
<%= link_to tag.name, tagged_url(:tag => tag.name) %>
</span>
<%# Need end here, as illustrated on the next line. %>
<% end %>
</div>
<% end %>
Take more care about how you're indenting your code. It matters and helps you to more easily prevent and debug syntax problems like this.
