Dependency management in Grails 1.2

Sun, 23 May 2010 00:00:00 +0200

Sometimes I get the impression that there are many Maven haters in the Groovy/Grails community – now with version 1.2 of the Grails framework they are able to abandon the evil satanic Grails Maven Plugin and embrace the neverending joys of a slim, nice, sexy dependency resolution dsl .. here we go .. lets define some dependencies wheee …

Our dependency configuration is defined in grails-app/config/BuildConfig.groovy as a property named grails.project.dependency.resolution:
```
grails.project.dependency.resolution = {
// here will be some dependencies
}
```

Named Queries in Grails 1.2

Tue, 06 Apr 2010 00:00:00 +0200

They built a nice new feature in Grails 1.2 called “named queries“. Named queries can be defined in a domain class as static properties and support the criteria builder syntax.

Examples

package testapp

class User {
	String name
	int iq
	int age

	static namedQueries = {
		dumbUsers {
			int referenceIq = 60
			lt 'iq' , referenceIq
		}

		nameStartsWith { letter ->
			like 'name', '${letter}%'
		}

		midAges {
			between('age', 20, 40)
		}

	}
}

// count dumb users
println User.dumbUsers.count()

// print amount of users, usernames starting with an 'a'
User.nameStartsWith('a').count()
