【中文标题】Drupal Organic Group 角色数据存储在哪里?我如何访问它?【英文标题】:Where is Drupal Organic Group Role Data stored? How do I access it? 【发布时间】:2011-08-31 22:20:18 【问题描述】:

我为我的组创建了一个自定义角色。 我已经为这个特殊角色分配了一个用户,他是该组的成员。 现在,我想通过 php 访问用户在组中的角色,但我在任何地方都找不到。 我仔细研究了用户和组的开发。我可以访问用户是用户 group_audience 数组中组的 成员 的事实,但不能访问他们在该组中的 角色

有什么建议吗?

【问题讨论】:

您使用的是什么版本的 Drupal 和 OG? 6 还是 7? OG 7.x-1.x-dev,Drupal 7 @Dan 我刚刚更新了我的答案;我认为它现在将具体回答您的问题。无论如何,我希望你能把它整理好,但如果我真的回答了你的问题,请给我一个闪亮的绿色勾号;o) 【参考方案1】:

背景

查看我们开发服务器上的 mysql 数据库,我们的 Drupal 数据库中似乎有一些与 OG 相关的表。我很确定在 devserver 上运行的版本是 og-7.x-1.x-dev。

og og_membership og_membership_type og_menu og_role og_role_permission og_users_roles field_data_og_membership_request field_revision_og_membership_request

它们的定义如下所示:

(我已从两个 field_* 表中删除了空的 Extras 列以避免水平滚动。)希望对您有帮助吗?

我的工作

我自己在自己的 Drupal 站点上搞砸了这个问题,结果发现og_membership 为每个组中的每个用户都有一行(我将type 缩写为og_membership_type_default):

mysql> select * from og_membership where gid = 324 and etid = 182905;
+--------+-----------------+--------+-------------+-----+-------+------------+
| id     | type            | etid   | entity_type | gid | state | created    |
+--------+-----------------+--------+-------------+-----+-------+------------+
| 223562 | og_m..._default | 182905 | user        | 324 | 1     | 1329388409 |
+--------+-----------------+--------+-------------+-----+-------+------------+
1 row in set (0.01 sec)

在这一行中,id 是表 og_membership 的自动递增标识符,etid 对应于相关用户的 users.uidgid 对应于表的 og.gid有问题的组。

所以如果我运行查询

update og_membership set gid = 38 where gid = 324;

然后将组#324 的所有成员移动到组#38(这是我刚需要做的,因为导入脚本中的错误)。

认为你的问题的答案是og_membership.type 对应于og_membership_type.name。看着那张桌子:

mysql> select * from og_membership_type;
+----+----------------------------+-------------+--------+--------+
| id | name                       | description | status | module |
+----+----------------------------+-------------+--------+--------+
|  1 | og_membership_type_default | Default     |      2 | og     |
+----+----------------------------+-------------+--------+--------+
1 row in set (0.00 sec)

,我认为og_membership_type.status对应og_role.rid

mysql> select * from og_role;
+-----+-----+----------------------+
| rid | gid | name                 |
+-----+-----+----------------------+
|   1 |   0 | non-member           |
|   2 |   0 | member               |
|   3 |   0 | administrator member |
+-----+-----+----------------------+
3 rows in set (0.00 sec)

实际答案

所以我认为你想要的查询是:

select og_role.name
from og_role
    inner join og_membership_type on og_role.rid = og_membership_type.status
    inner join og_membership on og_membership_type.name = og_membership.type
where og_membership.gid = $group_id;

其中$group_id 是相关组的og.gid。 (出现在 URL 中的 ID 是 og.etid,因此您可能需要在该查询中添加另一个 join
