我有以下 2 个 named_scopes:
named_scope :scope1, lambda { |pi_id|
{ :select => "DISTINCT REF_PRO.*",
:joins => "INNER JOIN LNK_PRO ON LNK_PRO.PR_PRO_FK = REF_PRO.RPR_ID
INNER JOIN EMI_SUBMISSION on EMI_SUBMISSION.SUB_ID = LNK_PRO.PR_SUBMISSION_FK
INNER JOIN EMI_PERSON on EMI_PERSON.PER_ID = EMI_SUBMISSION.SUB_PI_FK ",
:conditions=>["EMI_PERSON.PER_ID = ? ", pi_id],
:group => "REF_PRO.RPR_ID"
}
}
named_scope :scope2, lambda { |pi_id|
{ :select => "REF_PRO.*",
:joins => "INNER JOIN REF_USER ON REF_USER.USR_ID = REF_PRO.RPR_CREATED_BY
INNER JOIN LNK_USER_PI on LNK_USER_PI.USP_USER_FK = REF_USER.USR_ID ",
:conditions=>["LNK_USER_PI.USP_PI_ID = ? ", pi_id]
}
}
我需要加入他们的结果。
有没有办法合并两个结果集?如果不是,我如何修改一个 named_scope 以便它返回上述命名范围的组合结果?
非常感谢你的帮助
