我是 Grails 的新手。我想在我的应用程序注册期间使用自定义验证器来匹配两个密码。不幸的是，它不起作用。

Account.groovy

@Validateable
class Account {

    String login
    String password
    String confirm
    String passwordHashed
    char active
    static transients = ['password', 'confirm']     
    static belongsTo = Employee
    static hasMany = [role:Role]

    static constraints = {
        login unique:true, blank: false
        active nullable: true
        password blank: false, size: 5..15, validator:{ val, obj ->
            if(obj.password != obj.confirm ){
                return ['dontmatch']
            }
        }       
    }

    static mapping = {
        id generator: 'increment'
    }
}

AuthenticationController.groovy

class AuthenticationController {

    def signUp(Account accountInstance){

        if(accountInstance!= null){
            if (accountInstance.hasErrors()) {
                respond accountInstance.errors, view:'signUp'
                return
            }
            else{
                accountInstance.save(flush: true)
            }
        }
    }

}

消息属性

account.password.dontmatch=Podane hasła muszą się zgadzać

我不明白。我输入了两个不同的密码，然后单击了注册按钮，我没有看到验证失败时应该显示的错误消息。你可以帮帮我吗？

的调用validate()不见了：

if (!accountInstance.validate() || accountInstance.hasErrors()) {
  ...
}

将 的实际值与实际对象validator的属性相匹配。confirm

password blank: false, size: 5..15, validator:{ val, obj ->
    if( obj.confirm && val != obj.confirm ) { // val is password
        return ['dontmatch']
    }
}

我想而不是respond你想要的控制器

render (view: "signUp", model: [accountInstance: accountInstance])

您的视图需要accountInstance视图模型中的对象来呈现错误，因此您必须提供它。

你也可以这样做

return [accountInstance: accountInstance]

如果存在与当前动作同名的 gsp，grails 会自动渲染它。
