加入关于其主要关键以外的领域的另一表
原标题:Joining to another table on fields other than its primary key

Suppose I have Table_A,我希望加入到,>Table_B, on two areas they have, school_id, and 。 参看:

SELECT whatever
FROM Table_A
INNER JOIN Table_B 
 ON (Table_A.school_id = Table_B.school_id 
     AND Table_A.type_id = Table_B.type_id)

据我所知,达詹戈确实通过这些模式界定的外国/领土钥匙加入。 因此,如果要填写<代码>A.objects.filter(B__field2=“stuff”),除了在条款中填入<代码>外,还将在上加入<>。 是否有办法加入我选择的钥匙,如上面的QQQry?
