我有MongoDB Grails PLUGIN這樣的映射兩類:MongoDB的查詢許多一對多相當於使用Grails的MongoDB插件
類人:
class Person {
static mapWith="mongo"
String name
String email
static hasMany = [profiles: Profile]
static belongsTo = Profile
String toString(){
return name +" - " + (profiles)
} }
和類簡介:
class Profile{
static mapWith="mongo"
String abbreviation
String description
static hasMany = [people: Person]
String toString(){
return abbreviation + " - " + description
}}
如何查詢使用mongo提供的查找器將每個配置文件返回給用戶?
mongo查詢可能也有用!
此取景器不返回任何
def people = Profile.findAllByAbbreviation("example").people
對不起英文...
簡介.findAllByAbbreviation(「example」)*。people? – 2013-03-22 23:12:12
