    <p>I've been having some trouble though with a pseudofunction of a summary field with division of two fields.</p> <p>the original two fields are:</p> <pre><code>{name: 'purchasers', type: 'integer', rowLabelable: false, summarizable: 'sum', displayFunction: function(value){ return accounting.formatNumber(value)}}, {name: 'spend', type: 'float', rowLabelable: false, summarizable: 'sum', displayFunction: function(value){ return accounting.formatMoney(value)}} </code></pre> <p>with the pseudofunction being:</p> <pre><code>{ name: 'spendperpurch', type: 'float', pseudo: true, pseudoFunction: function(row){ return row.spend / row.purchasers }, summarizable: 'sum', displayFunction: function(value){ return accounting.formatMoney(value)} } </code></pre> <p>and it's just not aggregating right from the granu</p> <p>What I would like to do is essentially do a sum(row.spend) / sum(row.purchasers) group by filters instead of a </p> <p>for i in row Σ (row.spend/row.purchasers) , which is what is currently happening. </p> <p>e.g. if i have 100 rows with the calculated field spend/purchasers</p> <pre><code>date, purchasers, spend, spendperpurch 1 , 10 , 100 , 10 2 , 15 , 200 , 13.3 </code></pre> <p>if in my table i only want</p> <pre><code>purchasers, spend, spendperpurch </code></pre> <p>the current code gives me:</p> <pre><code>purchasers, spend, spendperpurch 25 , 300 , 23.3 </code></pre> <p>where what i really want is:</p> <pre><code>purchasers, spend, spendperpurch 25 , 300 , 12 </code></pre> <p>any ideas? I would greatly appreciate any help!</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.
