我有一个这样的课：
class Student {
const GENDER_MALE = "male",GENDER_FEMALE = "female";
/**
* @var string $gender
*
* @ORM\Column(name="gender",type="string",length=50,nullable=false)
* @Assert\NotBlank(message="Gender cannot be blank",groups={"new"})
* @Assert\Choice(choices = {"male","female"},message = "Choose a valid gender.",groups={"new"})
*/
private $gender;
我必须硬编码“男”和“女”的价值观.有可能做这样的事情吗？
choices = {self::GENDER_MALE,self::GENDER_FEMALE}
这是
Doctrine2 Annotation Reader (Constants)的一个特点.
你的解决方案
class Student
{
const GENDER_MALE = "male",GENDER_FEMALE = "female";
/**
* @var string $gender
*
* @ORM\Column(name="gender",nullable=false)
* @Assert\NotBlank(message="Gender cannot be blank",groups={"new"})
* @Assert\Choice(
* choices = {
* Student::GENDER_FEMALE: "Female",* Student::GENDER_MALE: "Male"
* },* message = "Choose a valid gender.",groups={"new"}
* )
*/
private $gender;
}
