Question

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。不幸的是不行。

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)
            }
        }
    }

}

messages.properties

account.password.dontmatch=Podane hasła muszą się zgadzać

我不明白。我输入两个不同的密码，然后单击“signUp”按钮，我看不到验证失败时应显示的错误消息。你能帮帮我吗？

Answer 1

validate()的电话丢失了：

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

Answer 2

将validator的实际值与实际对象的confirm属性匹配。

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

Answer 3

我认为而不是你想要的控制器中的respond

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

您的视图需要视图模型中的accountInstance对象呈现错误，因此您必须提供错误。

您也可以这样做

return [accountInstance: accountInstance]

如果有一个与当前操作同名的gsp，grails将自动呈现它。
