    <p>I have several domain classes that are related and I am trying to figure out how to implement a constraint that depends on multiple domains. The jist of the problem is:</p> <p>Asset has many Capacity pool objects</p> <p>Asset has many Resource objects</p> <p>When I create/edit a resource, need to check that total resources for an Asset doesn't exceed Capacity. </p> <p>I created a service method that accomplishes this, but shouldn't this be done via a validator in the Resource domain? My service class as listed below:</p> <pre><code> def checkCapacityAllocation(Asset asset, VirtualResource newItem) { // Get total Resources allocated from "asset" def allAllocated = Resource.createCriteria().list() { like("asset", asset) } def allocArray = allAllocated.toArray() def allocTotal=0.0 for (def i=0; i&lt;allocArray.length; i++) { allocTotal = allocTotal.plus(allocArray[i].resourceAllocated) } // Get total capacities for "asset" def allCapacities = AssetCapacity.createCriteria().list() { like("asset", asset) } def capacityArray = allCapacities.toArray() def capacityTotal = 0.0 for (def i=0; i&lt;capacityArray.length; i++) { capacityTotal += capacityArray[i].actualAvailableCapacity } if (allocTotal &gt; capacityTotal) { return false } } return true } </code></pre> <p>The problem I am having is using this method for validation. I am using the JqGrid plugin (with inline editing) and error reporting is problematic. If I could do this type of validation in the domain it would make things a lot easier. Any suggestions?</p> <p>Thanks so much!</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.
