Question

使用{ _id: ObjectID { _bsontype: 'ObjectID', id: 'W_?àÅÜY¼-íbO' }, // <- Problem salt: 'ULRtWgj0qgblPRbSPwTe4A==', displayName: 'test tester', provider: 'local', username: 'tester', created: Tue Jun 14 2016 06:36:48 GMT+0200 (Romance Daylight Time), roles: [ 'user' ], profileImageURL: 'modules/users/client/img/profile/default.png', referrers: { level1: ObjectID { _bsontype: 'ObjectID', id: 'W^_ó 5IE\u0013 N\u0010c' } }, // <- Also problem password: 'jXpp+RJIegHFKD50sL2aOlOUhE0rvYtSJZIDB244SDIw93yrbuFCTUJK3SZIs3F w0DdHOUzlQoLQwTGEcF67Kg==', email: 'test@example.com', lastName: 'tester', firstName: 'test', __v: 0 }和{ "_id" : ObjectId("575f89e0c5dc59bc2ded62d5"), // <- This is different! "salt" : "ULRtWgj0qgblPRbSPwTe4A==", "displayName" : "test tester", "provider" : "local", "username" : "tester", "created" : ISODate("2016-06-14T04:36:48.130Z"), "roles" : [ "user" ], "profileImageURL" : "modules/users/client/img/profile/default.png", "referrers" : { "level1" : ObjectId("575ebef32035ccc8134e1063") // <- This too! }, "password" : "jXpp+RJIegHFKD50sL2aOlOUhE0rvYtSJZIDB244SDIw93yrbuFCTUJK3S ZIs3Fw0DdHOUzlQoLQwTGEcF67Kg==", "email" : "test@example.com", "lastName" : "tester", "firstName" : "test", "__v" : 0 } >时出现问题，我有以下两种模式：

has_many

此帐户模型

belongs_to

我试图运行此查询：

  @primary_key {:guid, :integer, []}
  schema "characters" do
    field :name, :string
    field :race, :integer
    field :class, :integer
    field :gender, :integer
    field :level, :integer
    field :xp, :integer
    field :money, :integer
    field :online, :integer
    field :totaltime, :integer
    field :leveltime, :integer
    field :rest_bonus, :float
    field :is_logout_resting, :integer
    field :honor_highest_rank, :integer
    field :honor_standing, :integer
    field :stored_honor_rating, :float
    field :stored_dishonorable_kills, :integer
    field :stored_honorable_kills, :integer
    field :health, :integer
    field :power1, :integer
    field :power2, :integer
    field :power3, :integer
    field :power4, :integer
    field :power5, :integer
    belongs_to :account, Pugit.Account, references: :id
  end

这里唯一的重大区别是，我可能试图从另一个仓库（其他数据库）预加载

但是我收到了这个错误：

 schema "account" do
    field :username, :string
    field :sha_pass_hash, :string
    field :gmlevel, :integer, default: 0
    field :sessionkey, :string
    field :v, :string
    field :s, :string
    field :email, :string
    field :joindate, Ecto.DateTime
    field :last_ip, :string, default: "0.0.0.0"
    field :failed_logins, :integer, default: 0
    field :locked, :integer, default: 0
    field :last_login, Ecto.DateTime
    field :active_realm_id, :integer, default: 0
    field :expansion, :integer, default: 0
    field :mutetime, :integer, default: 0
    field :locale, :integer, default: 0

    has_many :characters, PugitWow.Character, foreign_key: :account
  end

任何信息都会很棒，谢谢

我的Pugit.AccountRepo.all(Pugit.Account) |> Pugit.CharRepo.preload([:characters])表的主键是** (Ecto.QueryError) deps/ecto/lib/ecto/association.ex:320: field `Pugit.Character.account` in `where` does not exist in the model source in query: from c in Pugit.Character, where: c.account in ^[1, 2, 3, 4, 21], order_by: [asc: c.account] (elixir) lib/enum.ex:1473: Enum."-reduce/3-lists^foldl/2-0-"/3 (elixir) lib/enum.ex:1151: Enum."-map_reduce/3-lists^mapfoldl/2-0-"/3 (ecto) lib/ecto/repo/queryable.ex:91: Ecto.Repo.Queryable.execute/5 (ecto) lib/ecto/repo/queryable.ex:15: Ecto.Repo.Queryable.all/4 (elixir) lib/enum.ex:1088: Enum."-map/2-lists^map/1-0-"/2

我的characters表的外键是guid

我的characters表的主键是account

Answer 1

这种情况正在发生，因为您的account关联使用的名称与外键account的字段相同。将该字段重命名为account_id，然后将其用作关联：

belongs_to :account, Pugit.Account

`where`中的字段`Struct`在查询中的模型源中不存在
