我下的版本3.13，跟着TP推荐的后盾网视频练习Rbac的时候，在添加用户并分配角色时，使用关联模型把他们关联起来，MANY_TO_MANY不好使，求帮助啊，卡在这了。
[2] => array(7) {
["id"] => string(1) "6"
["username"] => string(5) "liang"
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["logintime"] => string(10) "1431498856"
["loginip"] => string(9) "127.0.0.1"
["lock"] => string(1) "0"
["role"] => bool(false)
}
[3] => array(7) {
["id"] => string(1) "8"
["username"] => string(3) "adc"
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["logintime"] => string(10) "1431591987"
["loginip"] => string(9) "127.0.0.1"
["lock"] => string(1) "0"
["role"] => bool(false)



如果把MANY_TO_MANY注释 掉会得到NULL。
[2] => array(7) {
["id"] => string(1) "6"
["username"] => string(5) "liang"
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["logintime"] => string(10) "1431498856"
["loginip"] => string(9) "127.0.0.1"
["lock"] => string(1) "0"
["role"] => NULL
}
[3] => array(7) {
["id"] => string(1) "8"
["username"] => string(3) "adc"
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["logintime"] => string(10) "1431591987"
["loginip"] => string(9) "127.0.0.1"
["lock"] => string(1) "0"
["role"] => NULL


如果给MANY_TO_MANY前面加上self::说这玩意没定义。


很急啊，求大神帮忙帮忙
