meteor Yaga 本 :Admin Filtering by Logged in User

Question

我正在使用yogiben:admin包 meteor ，我希望当前登录的用户能够仅看到每个集合中他们自己的对象。

如何将订阅集成到管理中？它是自动成型的一部分吗？

所以我开始弄清楚了。

我使用此处描述的技术克隆了该包:https://stackoverflow.com/a/30864393/55124

现在我正在查看 lib/server/publish.coffee 文件来编辑出版物。

Meteor.publishComposite 'adminCollectionDoc', (collection, id) ->
    check collection, String
    check id, Match.OneOf(String, Mongo.ObjectID)
    if Roles.userIsInRole this.userId, ['admin']
        find: ->
            adminCollectionObject(collection).find(id)
        children: AdminConfig?.collections?[collection]?.children or []
    else
        @ready()

Meteor.publish 'adminUsers', ->
    if Roles.userIsInRole @userId, ['admin']
        Meteor.users.find()
    else
        @ready()

Meteor.publish 'adminUser', ->
    Meteor.users.find @userId

Meteor.publish 'adminCollectionsCount', ->
    handles = []
    self = @

_.each AdminTables, (table, name) ->
    id = new Mongo.ObjectID
    count = 0
    table = AdminTables[name]
    ready = false
    selector = if table.selector then table.selector(self.userId) else {}
    handles.push table.collection.find().observeChanges
        added: ->
            count += 1
            ready and self.changed 'adminCollectionsCount', id, {count: count}
        removed: ->
            count -= 1
            ready and self.changed 'adminCollectionsCount', id, {count: count}
    ready = true

    self.added 'adminCollectionsCount', id, {collection: name, count: count}

self.onStop ->
    _.each handles, (handle) -> handle.stop()
self.ready()

Meteor.publish null, ->
    Meteor.roles.find({})

但事实证明，这就像更改 lib/both/startup.js 中的 a 行一样简单

return AdminTables[name] = new Tabular.Table({
  name: name,
  collection: adminCollectionObject(name),
  pub: collection.children && adminTablePubName(name),
  sub: collection.sub,
  columns: columns,
  extraFields: collection.extraFields,
  dom: adminTablesDom,
  selector: collection.selector || function( userId ) {
    return { owner: userId };
  }

有一个空的选择器函数，我添加了返回所有者:userId。
