grails install-templates (Install base scaffolding files. Can then update them before generating scaffolding.
e.g. I update list default size to 50 (from 10)), Increase number of columns displayed in list tables (max by defauilt is 6 columns), changing if (i < 6){ { allows you to increase this (change in 2 places)

Maven integration
Build a new grails project with maven.
mvn org.apache.maven.plugins:maven-archetype-plugin:2.0-alpha-4:generate -DarchetypeGroupId=org.grails -DarchetypeArtifactId=grails-maven-archetype -DarchetypeVersion=1.2.0 -DgroupId=example -DartifactId=my-app
mvn initialize
Misc
- GORM Non numeric ID field
- Dependency Injection.
As usual it was working fine, and the problem was mine...
Dependency Injection (DI) is configured by default to occur by name. If you create a property in your Domain/ Controller/ Service class with the same name as another Service or property you want injected, then it will automatically get injected. See this article http://www.grails.org/Services
To inject the DataSource into your Service, All you need to do is add the line
def dataSource
to your Service. Thats all.. nothing else is needed.
I also had to add the following to initialize the java libraries dataSource, so I also needed
class BenefitService implements InitializingBean{
void afterPropertiesSet() {
println "Initializing BenefitService "+dataSource
BenefitWrapper.setDataSource(dataSource)
}
This all would work. My problem was I (helpfully) added an accessor method for the dataSource
def getDataSource(){return dataSource)
This simple method modifies the groovy class dataSource property, effectively making the setter of the dataSource unavailable, thus effectively blocking dependency injection.
Moral: Groovy is designed to help reduce the number of code lines you write. Don't add unneccessary lines or there may be unexpected side-effects.
