我有一个域类计划,如:
class Plan{
String name
static constraints={
name(unique:true,nullable:false)
}
}
另一个域类是User:
class User{
// Other attribures and code
// ....
Plan plan
static constraints = {
// other constraints..
plan(nullable:false, defaultValue: Plan.findByName("default"))
}
}
上面的代码给了我错误:
Caused by: java.lang.IllegalStateException: Method on class [mypackage.Plan] was used outside of a Grails application. If running in the context of a test using the mocking API or bootstrap Grails correctly.
at mypackage.User$__clinit__closure1.doCall(User.groovy:31)
上面的错误行是
plan(nullable:true,defaultValue: Plan.findByName("default"))
我也在BootStrap.groovy中定义了默认计划:
if(!Plan.findByName("default")){
new Plan(name: "default",brandPartner: null,secRole: null).save(failOnError: true, flush: true)
log.info("initPlans: No default plan found, hence created a new default plan!")
}
那么我应该如何设置plan属性的默认值(用户定义的类型)?
答案 0 :(得分:1)
使用拦截器而不是约束:
class User{
Plan plan
static beforeInsert = {
if( !plan ) Plan.withTransaction {
plan = Plan.findByName 'default'
}
}
}
