我遇到了CakePHP的问题。我测试了很多方法,但无法找到解决方案。 我有这些表:
用户
id
name
country_code
国家
code
title
技能
code
title
角色
id
title
事件
id
title
country_code
events_users
event_id
user_id
role_id
skill_code
事件hasAndBelongsToMany用户和events_users是我的联接表,当我读取数据时,它给我这样的东西:
array(
(int) 0 => array(
'Event' => array(
'id' => '1',
'title' => '40th WorldSkills Competitions',
'year' => '2011',
'country_code' => 'LV',
'created' => '2013-02-08 00:00:00'
),
'User' => array(
(int) 0 => array(
'password' => '*****',
'id' => '14',
'name' => 'test',
'family' => 'testian',
'username' => 'test@mail.me',
'country_code' => 'BR',
'telphone' => '465465',
'avatar' => 'avatar_51299c1da268f20110912043238_rodekamp_04.jpg',
'address' => 'AA',
'admin' => '0',
'created' => '2013-02-24 05:50:37',
'modified' => '2013-02-24 05:50:37',
'EventsUser' => array(
'id' => '1',
'user_id' => '14',
'event_id' => '1',
'role_id' => '1',
'skill_code' => '17',
'manage' => '100'
)
),
(int) 1 => array(
'password' => '*****',
'id' => '5',
'name' => 'John',
'family' => 'Smith',
'username' => 'john@me.com',
'country_code' => 'IE',
'telphone' => '147',
'avatar' => '20120504124040_franziska_peter_ok.jpg',
'address' => 'No 55',
'admin' => '0',
'created' => '2013-02-10 15:24:13',
'modified' => '2013-02-10 15:28:50',
'EventsUser' => array(
'id' => '2',
'user_id' => '5',
'event_id' => '1',
'role_id' => '2',
'skill_code' => '17',
'manage' => '0'
)
),
(int) 2 => array(
'password' => '*****',
'id' => '4',
'name' => 'hadi',
'family' => 'mm',
'username' => 'design.zerzem@gmail.com',
'country_code' => 'AE',
'telphone' => '415456',
'avatar' => '',
'address' => 'sadjfklsaf asd f',
'admin' => '0',
'created' => '2013-02-10 09:01:28',
'modified' => '2013-02-24 06:43:42',
'EventsUser' => array(
'id' => '3',
'user_id' => '4',
'event_id' => '1',
'role_id' => '4',
'skill_code' => '17',
'manage' => '0'
)
)
)
没关系,但是对于events_users,我想要获取有关events_users(skill_code和role_id)中的技能和角色的数据。我应该如何创建模型来提供所有这些数据?
答案 0 :(得分:2)
我认为阅读"hasMany Through"应该回答你的问题。
基本上,您为连接表创建模型,然后您可以像任何其他模型一样关联它。
当您去检索数据时,请使用CakePHP's Containable behavior(如果您以前没有使用过它,请准备好上瘾)。
