I just followed the user guide to add a dynamic method to controllers using trait from plugin.
The following are my code:
---Trait---
package com.ylw.gorm
trait DateTrait {
Date currentDate() {
return new Date()
}
}
---TraitInjector---
package com.ylw.gorm
import grails.compiler.traits.TraitInjector
import groovy.transform.CompileStatic
@CompileStatic
class ControllerTraitInjector implements TraitInjector {
@Override
Class getTrait() {
DateTrait
}
@Override
String[] getArtefactTypes() {
['Controller'] as String[]
}
}
---Controller---
@Transactional(readOnly = true)
class MyDomainController {
static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]
def testTrait() {
render "The current date is -> " + currentDate()
}
...
}
I am expecting the controller will know the currentDate() method from the trait. But I got the following error in the browser:
Caused by MissingMethodException: No signature of method: com.ylw.gorm.MyDomainController.currentDate() is applicable for argument types: () values: [] Possible solutions: create() 90 | methodMissing in grails.artefact.gsp.TagLibraryInvoker$Trait$Helper - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 12 | $tt__testTrait in com.ylw.gorm.envers.AuditedDomainController 93 | doInTransaction in grails.transaction.GrailsTransactionTemplate$2 90 | execute in grails.transaction.GrailsTransactionTemplate 1145 | runWorker in java.util.concurrent.ThreadPoolExecutor 615 | run in java.util.concurrent.ThreadPoolExecutor$Worker 745 | run . . . in java.lang.Thread
What I did wrong?
Thanks for help! Yingliang
