Fwd: [grails-user] service injection in GORM event handlers, is it possible?

[Sergey Bondarenko]

Hi Grails developers!

Could you please look at this issue?
It looks like service injection does not work in domain classes when onLoad closure is invoked.
I am using Grails 1.1.1.

Thanks a lot!

Just checked. It works for beforeInsert and beforeUpdate, but does not work for onLoad event.
Could you please check if it works for onLoad in your app?

Thanks a lot!

Daniel,

Well, this service is being injected into other services and cotroller without problems.

The service is from Acegi plugin. My Grails version is 1.1.1 (maybe that makes a difference?).

I'll try to do the same with my own service.

Thanks for helping me!

Something else is probably amiss.  I've been able to access services from hibernate event handlers without issue.  Do you know that your service is being injected into other classes or use cases without issue?

Hi folks!


I just tried to get service injection working in GORM event handlers. I wanted to implement domain-instance security checks this way.
It looks like service injection in usual methods works properly, but service is not injected in GORM events.

Does anyone else have the same problem?

The problem looks similar to http://jira.codehaus.org/browse/GRAILS-1749


Some details below.

I wanted to implement something like this:
class Department {
    def authenticateService

    static belongsTo = Customer
   
    static transients = ['authenticateService']

    def onLoad = {
        def currentUser = User.get(authenticateService.userDomain()?.id)
        def currentCustomer = Customer.get(currentUser?.customer?.id)
        if (customer != currentCustomer) {
            throw new IllegalStateException("Cannot read data of another customer")
        }
    }
}


But it looks like service is not injected, and I always receive NPE.



Any help is appreciated!

Sergey
