    <p>In tag#show I list all entries with that tag. At the bottom of the page I'd like to have something like: "Related Tags: linked, list, of, related tags" My view looks like:</p> <pre><code>&lt;h2&gt;&lt;%= link_to 'Tag', tags_path %&gt;: &lt;%= @tag.name.titleize %&gt;&lt;/h2&gt; &lt;% @entries.each do |entry| %&gt; &lt;h2&gt;&lt;%= link_to h(entry.name), entry %&gt;&lt;/h2&gt; &lt;%- unless entry.phone.empty? -%&gt; &lt;p&gt;&lt;%= h(entry.phone) %&gt;&lt;/p&gt; &lt;%- end -%&gt; &lt;%- unless entry.address.empty? -%&gt; &lt;p&gt;&lt;%= h(entry.address) %&gt;&lt;/p&gt; &lt;%- end -%&gt; &lt;%- unless entry.description.empty? -%&gt; &lt;p&gt;&lt;%= h(entry.description) %&gt;&lt;/p&gt; &lt;%- end -%&gt; &lt;p2&gt;&lt;%= link_to "more...", entry %&gt;&lt;p2&gt; &lt;% end %&gt; Related Tags: &lt;% @related.each do |tag| %&gt; &lt;%= link_to h(tag.tags), tag %&gt; &lt;% end %&gt; </code></pre> <p>tags_controller.rb:</p> <pre><code>def show @title = Tag.find(params[:id]).name @tag = Tag.find(params[:id]) @entries = Entry.paginate(Entry.find_tagged_with(@tag), :page =&gt; params[:page], :per_page =&gt; 10, :order =&gt; "name") @related = Entry.tagged_with(@tag, :on =&gt; :tags) end </code></pre> <p>Every entry has at least one tag, it's required by the entry model. I'd like duplicate tags ignored and the current tag (the tag that the list belongs to) ignored. My current code displays this:</p> <p>Related Tags: Gardens Gardens ToursGardens</p> <p>Gardens is a link to the entry, not the tag gardens. ToursGardens is a link to the entry that includes those tags.</p> <p>My desired result would be:</p> <p>Related Tags: Gardens, Tours</p> <p>Each link would link to it's associated tag. Can anyone help me achieve this? I tried using a div_for but I don't think that was right.</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.
