【问题描述】：

我正在接管一个网站。我再也联系不到以前的开发者了。他决定使用 cube.js，并且曾经向我展示了一个带有图表的工作 KPI 页面。现在，我正试图让页面在我身边工作，并了解他做了什么。

我已经在我的机器上安装了 cube.js。我们数据库中的集合是comments、folders、logs、posts、sessions、subscribers、users。我使用cubejs generate -t users 和cubejs generate -t logs 生成Users.js 和Logs.js。比如这里是生成的Users.js：

cube(`Users`, 
  sql: `SELECT * FROM news.users`,

  joins: 

  ,

  measures: 
    count: 
      type: `count`,
      drillMembers: [currentname, currentprovider, googleJsonDisplayname, googleJsonId, googleJsonNameFamilyname, googleJsonNameGivenname, googleDisplayname, googleId, googleNameFamilyname, googleNameGivenname, googleProvider, localId, localProvider, firstdate]
    ,

    googleJsonCircledbycount: 
      sql: `$CUBE.\`google._json.circledByCount\``,
      type: `sum`,

    googleJsonNameFamilyname: 
      sql: `$CUBE.\`google._json.name.familyName\``,
      type: `string`,
      title: `Google. Json.name.familyname`
    ,

    googleJsonNameGivenname: 
      sql: `$CUBE.\`google._json.name.givenName\``,

    googleGender: 
      sql: `$CUBE.\`google.gender\``,
      type: `string`,
      title: `Google.gender`
    ,

    googleId: 
      sql: `$CUBE.\`google.id\``,

      type: `string`,
      title: `Google.name.familyname`

    googleNameGivenname: 
      sql: `$CUBE.\`google.name.givenName\``,
      type: `string`,

    ,

    googleProvider: 
      sql: `$CUBE.\`google.provider\``,
      type: `string`,
      title: `Google.provider`
    ,

    localExpired: 
      sql: `$CUBE.\`local.expired\``,
      type: `string`,
      title: `Local.expired`
    ,

    localFirstapp: 
      sql: `$CUBE.\`local.firstApp\``,
      type: `string`,
      title: `Local.firstapp`
    ,

    localHash: 
      sql: `$CUBE.\`local.hash\``,
      type: `string`,
      title: `Local.hash`
    ,

    localId: 
      sql: `$CUBE.\`local.id\``,
      type: `string`,
      title: `Local.id`
    ,

    localProvider: 
      sql: `$CUBE.\`local.provider\``,
      type: `string`,
      title: `Local.provider`
    ,

    localSalt: 
      sql: `$CUBE.\`local.salt\``,
      type: `string`,
      title: `Local.salt`
    ,

    localType: 
      sql: `$CUBE.\`local.type\``,
      type: `string`,
      title: `Local.type`
    ,

    localVerificationcode: 
      sql: `$CUBE.\`local.verificationCode\``,
      type: `string`,
      title: `Local.verificationcode`
    ,

    localVerified: 
      sql: `$CUBE.\`local.verified\``,
      type: `string`,
      title: `Local.verified`
    ,

    firstdate: 
      sql: `$CUBE.\`firstDate\``,
      type: `time`
    
  
);

然后，我在我的机器上启动了 cube.js 后端和他的页面localhost:8000/kpi。有Error: Error: Cube 'Customs' not found for path 'Customs.count'、Error: Error: Cube 'Customs' not found for path 'Customs.count'和Error: Error: Can't find join path to join 'Users', 'Logs'之类的错误：

这是之前的开发者如何定义他的query.ts：

export const getQueryUserByType = (dateRange: any, granularity: any) => (
  measures: ['Users.count'],
  dimensions: ['Users.localType'],
  timeDimensions: dateRange
    ? [
        
          dimension: 'Logs.date',
          dateRange: dateRange,
          granularity,
        ,
      ]
    : [
        
          dimension: 'Logs.date',
          granularity,
        ,
      ],
);

export const getQueryUserPageVist = (dateRange: any, granularity: any) => (
  measures: ['Users.count'],
  dimensions: ['Logs.url'],
  timeDimensions: dateRange
    ? [
        
          dimension: 'Logs.date',
          dateRange: dateRange,
          granularity,
        ,
      ]
    : [
        
          dimension: 'Logs.date',
          granularity,
        ,
      ],
  filters: [
    
      member: 'Logs.actionThetype',
      operator: 'equals',
      values: ['VisitPage'],
    ,
  ],
);

export const getQueryCustomByApp = (dateRange: any, granularity: any) => (
  measures: ['Customs.count'],
  dimensions: ['Customs.offerdisplayname'],
  timeDimensions: dateRange
    ? [
        
          dimension: 'Customs.timestamp',
          dateRange: dateRange,
          granularity,
        ,
      ]
    : [
        
          dimension: 'Customs.timestamp',
          granularity,
        ,
      ],
);

谁能告诉Error: Error: Cube 'Customs' not found for path 'Customs.count'、Error: Error: Cube 'Customs' not found for path 'Customs.count' 和Error: Error: Can't find join path to join 'Users', 'Logs' 之类的错误是什么意思？我该如何解决它们？

【参考方案1】：

您的应用程序缺少 Cube.js 架构，这是 Cube.js 部署的重要组成部分。您应该尝试找到这个丢失的源代码，或者根据您的仪表板 ui 应用程序重新开发它。

由于错误状态，您缺少Customs 多维数据集定义以及Users 和Logs 之间的连接定义。您可以在此处了解有关联接的更多信息：https://cube.dev/docs/joins
