grails枚举类型验证无法正常工作 [英] grails enum type validation not working as expected

问题描述

我有一个单元测试是违规违规，不应该在哪里。我正在测试如果有效的枚举设置为域类的变量。

I have a unit test that is failing on a constraint violation, where it should not be. I'm testing if valid enums are set as variables of a domain class.

我的枚举：

public enum GenderPreference {
    M('Male'),
    F('Female'),
    A('Any')

    final String value

    GenderPreference(String value) {
        this.value = value
    }
    public String toString() {
        value
    }
    public String getKey() {
        name()
    }
    public String getValue() {
        value
    }
}

我的域名：

class Profile {
    GenderPreference genderPreference

    static constraints = {
        genderPreference (blank:true, nullable:true)
    }
}

我的单元测试：

罚款：

def instance = new Profile(genderPreference: GenderPreference.M)
assertTrue instance.validate(['genderPreference'])

这应该会失败但不会。 QQQ不是有效的枚举

this should fail but does not. QQQ is not a valid enum

instance = new Profile(genderPreference: 'QQQ')
assertFalse instance.validate(['genderPreference'])

我正在使用grails 2.2.4。我认为在旧版本中，还有其他一些东西必须添加到枚举的域约束，但我认为这应该工作。缺少什么？

I'm using grails 2.2.4. I think in older versions there was something else that had to be added to the domain constraints for enums, but I thought this should work. What's missing?

推荐答案

您可以使用inList向您的枚举添加约束

You can use inList to add constraints to your enum

static constraints = {
    genderPreference blank:true, nullable:true,
                     inList: GenderPreference.values() as List
}
