我正在构建一个多租户应用程序并在添加指向同一个表的多个关系后遇到错误：

Uncaught Error: More than one relationship was found for teams and users

执行此查询时：

const data = await supabaseClient.from('organizations')
.select(`
  *,
  teams(
    id,
    org_id,
    name,
    members:users(
      id,
      full_name,
      avatar_url
    )
  )
`);

我有以下表结构（为简洁起见，省略了一些字段）：

table users (
  id uuid PK
  full_name text
  email text
)

table organizations (
  id uuid PK
  ....
)

table organization_memberships (
  id uuid PK
  organization_id uuid FK
  user_id uuid FK
  role ENUM
)

table teams (
  id uuid PK
  name text PK
)

table team_memberships (
    id uuid PK
    team_id uuid FK
    user_id uuid FK
    role ENUM
)

table team_boards (
  id uuid PK
  team_id uuid FK
  owner_id uuid FK
)

在底层，Supabase 使用 PostREST 进行查询。而且我已经从错误消息中破译出查询是模棱两可的，并且不确定要满足哪些关系。我不确定如何告诉 Supabase 在此特定查询中使用哪个关系以避免此错误。

这是 postREST 中更详细的控制台错误：

{
  hint: "By following the 'details' key, disambiguate the request by changing the url to /origin?select=relationship(*) or /origin?select=target!relationship(*)",
  message: 'More than one relationship was found for teams and users',
  details: [
    {
      origin: 'public.teams',
      relationship: 'public.team_memberships[team_memberships_team_id_fkey][team_memberships_user_id_fkey]',
      cardinality: 'm2m',
      target: 'public.users'
    },
    {
      origin: 'public.teams',
      relationship: 'public.team_boards[team_boards_team_id_fkey][team_boards_owner_id_fkey]',
      cardinality: 'm2m',
      target: 'public.users'
    }
  ]
}

深入研究 PostgREST 文档，结果发现我正在寻找的是消歧运算符，!.

工作查询看起来像这样（请注意，我们正在消除使用哪个关系来满足members查询的歧义）：

const data = await supabaseClient.from('organizations')
.select(`
  *,
  teams(
    id,
    org_id,
    name,
    members:users!team_memberships(
      id,
      full_name,
      avatar_url
    )
  )
`);
