Question

关于grails的问题

首先是我的两个领域类：
package races

class Registration {

Race race
String name
Date dateOfBirth
String gender='F'
String postalAddress
String emailAddress
Date createAt=new Date()
static belongsTo=Race
static optionals=["postalAddress"]

static constraints={
name(maxLength:50,blank:false)
dateOfBirth(nullable:false)
gender(inList["M","F"])
postalAddress(maxLength:255)
emailAddress(maxLength:50,email:true)
race(nullable:false)
createAt()
}

}
========================================

package races

class Race {

String name
Date startDateTime
String city
String state
Float distance
Float cost
Integer maxRunners=100000

static hasMany=[registrations:Registration]

static constraints={
name(maxLength:50,blank:false)
startDateTime(validator:{return (it > new Date())})
city(maxLength:30,blank:false)
state(inList:['GA','NC','SC','VA'],blank:false)
distance(min:3.1f,max:100f)
cost(min:0f,max:999.99f)
maxRunners()
}
}

所报的错误是没有相关属性races.Registration，我想说，我又这个类啊，为什么还包这个错误？我只是想实现基本的增删改查，还有一些校验，脚手架的配置没问题的，这个是我跟着《grails入门》练习的时候遇到的问题

Answer 1

gender(inList["M","F"])
改成：
gender(inList:["M","F"])

少个了“：”号而已。结贴啊兄弟，呵呵
