    copied!<p>I have the following requirement. </p> <p>Ex: There is a transaction table where it has columns say, transaction_name and amount. I want to loop through the transactions and display their details (transaction_name and amount) and finally I want to display the total amount (sum of all the amounts) in the head (before the loop) section of my page. (Think about it as a summary display)</p> <p>Example page structure would be like</p> <p><strong>Sum of all the transactions - 200</strong></p> <p>transaction amount trn1 100 trn2 50 trn3 50</p> <p>And I tried to use yield and content_for tag but no luck. </p> <p>my code is as follows (i'm calling inside my erb file.)</p> <pre><code>&lt;%= yield :transaction_summary %&gt; &lt;table&gt; &lt;% total_amount = 0%&gt; &lt;%for transaction in @transactions%&gt; &lt;tr&gt; &lt;td&gt;&lt;%= transaction.transaction_name %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= transaction.amount %&gt;&lt;/td&gt; &lt;% total_amount += transaction.amount %&gt; &lt;/tr&gt; &lt;%end%&gt; &lt;/table&gt; &lt;% content_for :transaction_summary do %&gt; &lt;h1&gt; Sum of all the transactions - &lt;%= total_amount %&gt; &lt;/h1&gt; &lt;% end %&gt; </code></pre> <p>And </p> <p>I'm using with inside a view (<strong>not inside a layout</strong>) </p> <p>I'm using rails 2.2.2</p> <p>Please help me and let me know if there is a better way</p> <p>thanks in advance</p> <p>cheers</p> <p>sameera</p> <p>EDIT: </p> <p><strong>Actually what I want to do is , Display some details before a particular loop where those details can be collected after the loop</strong></p> <p>Ex: If i have an array of transaction objects, I want to show a count of pass and failed transactions before the transactions loop in my view</p> <p>thanks</p>
