Quick Tip: domain class properties in Grails

Ever wanted to see if a domain class had a many-to-many association in a Grails controller? What about getting a list of persistent properties? In this post, I will outline a quick solution that Jakob Külzer and I figured out for a recent project…

The secret to accessing Grails domain class properties outside of a domain class is to use the DefaultGrailsDomainClass.

Let’s say I have a domain object Foo, In the FooController, I can call

def fooDomain = new DefaultGrailsDomainClass( Foo.class )

then I can call

fooDomain.properties.each{
println “${it.name} ${it.oneToMany}”
}

Which will show me all the properties for this domain class and whether the result is a one to many association.

You can access the full API here : DefaultGrailsDomainClass

Use carefully!

The NBC Olympic site and other stupid design choices

Here are a couple of bad design decisions I’ve run into that have ruined my interaction with websites or products. They all relate in some way to Flex and Grails, so I thought I would put them up somewhere.
