How to get multiple records join into one table or use contain with conditions? - mysql

Question

I'm using cakePHP 2.6.4.
I have two tables AgentChat and AgentChatMember.
AgentChat hasMany AgentChatMember,
AgentChatMember belongsTo AgentChat.
AgentChat have: id, team_id, agent_chat_member_count fields.
AgentChatMember have: id, agent_chat_id, user_id fields.
I want to find AgentChat by chat_team_id and agent_chat_member_count,
and AgentChatMember as contain with user_id conditions.
$options['contain'] = array('AgentChatMember');
$options['conditions']['AgentChat.agent_chat_member_count'] = count($user_ids);
$options['conditions']['AgentChat.chat_team_id'] = $chat_team_id;
$res = $this->AgentChat->find('first', $options);
and $res is:
'AgentChat' => array(
'id' => '1',
'agent_message_count' => '0',
'agent_chat_member_count' => '2',
'chat_team_id' => '14',
'created' => '2015-05-06 09:52:31',
'updated' => '2015-05-06 09:52:31'
),
'AgentChatMember' => array(
(int) 0 => array(
'id' => '1',
'agent_chat_id' => '1',
'user_id' => '26',
'created' => '2015-05-06 09:52:31'
),
(int) 1 => array(
'id' => '2',
'agent_chat_id' => '1',
'user_id' => '21',
'created' => '2015-05-06 09:52:31'
)
)
By this i get what i want except fact i cant set user_id condition to AgentChatMember like this: $options['conditions']['AgentChatMember.user_id'] = $user_ids;
When i'm using joins instead of contain i can set user_id conditions, but i get result like this:
(int) 0 => array(
'AgentChat' => array(
'id' => '1',
'agent_message_count' => '0',
'agent_chat_member_count' => '2',
'chat_team_id' => '14',
'created' => '2015-05-06 09:52:31',
'updated' => '2015-05-06 09:52:31'
),
'AgentChatMember' => array(
'id' => '2',
'agent_chat_id' => '1',
'user_id' => '21',
'created' => '2015-05-06 09:52:31'
)
),
(int) 1 => array(
'AgentChat' => array(
'id' => '1',
'agent_message_count' => '0',
'agent_chat_member_count' => '2',
'chat_team_id' => '14',
'created' => '2015-05-06 09:52:31',
'updated' => '2015-05-06 09:52:31'
),
'AgentChatMember' => array(
'id' => '2',
'agent_chat_id' => '1',
'user_id' => '26',
'created' => '2015-05-06 09:52:31'
)
),
...
Its possible to get multiple records join into one table or contain with conditions on it?
How can i achieve that?

Answer 1

You can pass conditions to the contain:-
$res = $this->AgentChat->find(
'first',
array(
'contain' => array(
'AgentChatMember' => array(
'conditions' => array(
'AgentChatMember.user_id' => $userIds
)
)
),
'conditions' => array(
'AgentChat.agent_chat_member_count' => count($userIds),
'AgentChat.chat_team_id' => $chatTeamId
)
)
);
Just as an aside, you should really be camel casing your variables in CakePHP. See the Coding Standards in the documentation.
