    <p>Assuming two database tables: <code>Funds</code> and <code>Prices</code>, in which <code>Funds hasMany Prices</code>.</p> <p>What I wanted to do is to retrieve the latest 15 prices of a particular fund in a certain scenario. Is there a means in CakePHP to make a <code>$this-&gt;Fund-&gt;find('all')</code> call that would allow me to limit the number of rows to be retrieved from the associated <code>Price</code> table?</p> <p><em>Note that I prefer not setting the <code>'limit'</code> option in the <code>Fund</code> model's <code>$hasMany</code> variable.</em></p> <p><strong>Note on accepted answer [Nov 2]:</strong></p> <p><a href="https://stackoverflow.com/questions/1657363/how-to-limit-the-the-number-of-row-retrieved-from-an-associated-table-in-cakephp/1657391#1657391">In Jason's answer which I had accepted</a>, I personally opt for the <code>bindModel</code> solution as I felt despite feeling a bit “hack-y”, it bodes much better with me as to make a one-off override on the default Model bindings.</p> <p>The code I used is as follows:</p> <pre><code>$this-&gt;Fund-&gt;bindModel(array( 'hasMany' =&gt; array( 'Price' =&gt; array( 'limit' =&gt; 15, 'order' =&gt; 'Price.date DESC' ) ) ); </code></pre> <p>No <code>unbindModel</code> is necessary.

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.
