我正在尝试为字符串状态添加自定义验证器,该验证器应检查字符串国家/地区是否为“美国”,然后状态应为“其他”。如果国家/地区不是“美国”并且州是“其他”,那么它应该抛出错误。
此外,我想为国家/地区添加一个自定义验证器来执行相同的操作。
请在下面找到我的域类的代码。
package symcadminidp
import java.sql.Timestamp
import groovy.transform.ToString
@ToString
class Account {
static auditable = [ignore:['dateCreated','lastUpdated']]
String organization
String organizationUnit
String status
String address1
String address2
String zipcode
String state
String country
Timestamp dateCreated
Timestamp lastUpdated
Account(){
status = "ENABLED"
}
static hasMany = [samlInfo: SAMLInfo, contacts: Contact]
static mapping = {
table 'sidp_account_t'
id column: 'account_id', generator:'sequence', params:[sequence:'sidp_seq']
contacts cascade:'all'
accountId generator:'assigned'
organization column:'org'
organizationUnit column:'org_unit'
zipcode column:'zip'
dateCreated column:'date_created'
lastUpdated column:'date_updated'
}
static constraints = {
organization size: 1..100, blank: false
organizationUnit size: 1..100, blank: false, unique: ['organization']
//The organizationUnit must be unique in one organization
//but there might be organizationUnits with same name in different organizations,
//i.e. the organizationUnit isn't unique by itself.
address1 blank:false
zipcode size: 1..15, blank: false
contacts nullable: false, cascade: true
status blank:false
//state ( validator: {val, obj -> if (obj.params.country.compareTocompareToIgnoreCase("usa")) return (! obj.params.state.compareToIgnoreCase("other"))})
//it.country.compareToIgnoreCase("usa")) return (!state.compareToIgnoreCase("other"))}
}
}
当我尝试添加上面注释掉的代码时,出现以下错误:
URI:/symcadminidp/帐户/索引 类:groovy.lang.MissingPropertyException 消息:没有这样的属性:类的参数:symcadminidp.Account
我是 grails 和 groovy 的新手,非常感谢有关此问题的任何帮助。
最佳答案
验证器 ( obj ) 的第二个值是 Account 域类。
A custom validator is implemented by a Closure that takes up to three parameters. If the Closure accepts zero or one parameter, the parameter value will be the one being validated ("it" in the case of a zero-parameter Closure). If it accepts two parameters the first is the value and the second is the domain class instance being validated.
http://grails.org/doc/latest/ref/Constraints/validator.html
你的验证器应该是这样的
state validator: { val, obj ->
return ( obj.country.toLowerCase() == 'usa' ) ?
( val.toLowerCase() != 'other' ) :
( val.toLowerCase() == 'other' )
}
