说明:grails 1.1部分新特性,我只是看 grails 的fisheye 代码链接到的jira 看到的
具:nabble forum 消息:grails 1.1beta1 将会在 11月下旬发布,beta2版本计划 12月底,rc正式版本要到 2009-1月份
1)支持 hibernate 的dynaimc-update 就是只对修改过的数据进行更新,通过下面方法
static mapping = { dynamicUpdate true dynamicInsert true }
2)对集合的支持 http://jira.codehaus.org/browse/GRAILS-1023
class Person { static hasMany = [nicknames:String ] }
GORM now supports basic collection types using a join table:
person_id string 1 "joejoe" 1 "yoyo"
Grails will map a new join table called "person_nicknames":
You can change the mapping using the joinTable argument:
class Person { static hasMany = [nicknames:String] static mapping = { hasMany joinTable:[name:'bunch_o_nicknames', key:'person_id', column:'nickname', type:"text"] } }
