    copied!<p>I am building a sample site to familiarize myself with RoR. I followed the book "Agile Web Development with Rails" up to a point, and now I am experimenting and using it as a reference, however I haven't been able to find the answer to my problem. </p> <p>I have two models of interest, one is supermarketchain and the other supermarket. Obviously, a supermarket chain has a bunch of supermarkets. What I am trying to do is get the basic "show" page for a single supermarket chain to display a list of the supermarkets that belong to it. </p> <p>I also didn't want to repeat myself (because apparently it's a Very Bad Thing), and so I thought I could use "render" to insert supermarket's index.html.erb into the supermarketchain/show.html.erb page, like this: </p> <pre><code>&lt;%= render :template =&gt; 'supermarkets/index' %&gt; </code></pre> <p>However, that produced zero output on the page. </p> <p>My next approach was to make this partial: </p> <pre><code>&lt;div id="supermarket-list"&gt; &lt;h1&gt;&lt;%= I18n.t "supermarket.title" %&gt;&lt;/h1&gt; &lt;table&gt; &lt;% for s in @supermarkets %&gt; &lt;tr class="&lt;%= cycle('list-line-odd', 'list-line-even') %&gt;"&gt; &lt;td&gt; &lt;%= s.supermarketchain.name %&gt; &lt;/td&gt; &lt;td&gt; &lt;%= s.address %&gt; &lt;/td&gt; &lt;td class="list-actions"&gt; &lt;%= link_to I18n.t("general.show"), s%&gt; &lt;br/&gt; &lt;%= link_to I18n.t("general.edit"), edit_supermarket_path(s) %&gt; &lt;br /&gt; &lt;%= link_to I18n.t("general.delete"), s, :confirm =&gt; I18n.t("general.confirmation"), :method =&gt; :delete %&gt; &lt;/td&gt; &lt;/tr&gt; &lt;%end%&gt; &lt;/table&gt; &lt;/div&gt; </code></pre> <p>And then use:</p> <pre><code>&lt;% @supermarkets = Supermarket.all %&gt; &lt;%= render :partial =&gt; 'supermarkets/supermarket' %&gt; </code></pre> <p>To insert it on the supermarketchain's show page. </p> <p>What I am wondering is whether this is a good practice. It seems to me weird to initialize a variable for use by a partial, when what I want displayed is the exact result of the "index" action of the supermarkets controller. Comments? </p> <p>Please ask for any needed clarifications. </p>
