【问题描述】:
我正在使用一个设计模型进行注册,其中包含了其他字段。
这是我的用户表架构
create_table "users", force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=utf8" do |t|
t.string "provider", default: "email", null: false
t.string "uid", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.string "confirmation_token"
t.datetime "confirmed_at"
t.datetime "confirmation_sent_at"
t.string "unconfirmed_email"
t.string "username", null: false
t.string "email", null: false
t.integer "role", default: 0, null: false
t.datetime "premium_expires_at"
t.string "token", default: "", null: false
t.text "tokens", limit: 65535
t.datetime "created_at"
t.datetime "updated_at"
t.string "avatar"
t.index ["confirmation_token"], name: "index_users_on_confirmation_token", unique: true, using: :btree
t.index ["email"], name: "index_users_on_email", unique: true, using: :btree
t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true, using: :btree
t.index ["uid", "provider"], name: "index_users_on_uid_and_provider", unique: true, using: :btree
t.index ["username"], name: "index_users_on_username", unique: true, using: :btree
end
但是,当通过 activeRecord (User model) 查询表时,我无法获取属于设计的某些列。
例子
userList = User.select("id, confirmation_token, confirmed_at, username, uid, role")
记录 userList 给我
#<ActiveRecord::Relation [#<User id: 1, uid: "foo@foo.com", username: "bowie", role: "admin", avatar: nil>, #<User id: 2, uid: "bar@bar.com", username: "wilson", role: "user", avatar: nil>, #<User id: 3, uid: "sp@sp.com", username: "Cartman", role: "user", avatar: nil>]>
confirmation_token 字段和confirmed_at 令牌字段未被检索。还有什么我应该做的吗?
【问题讨论】:
-
puts userList.confirmation_token或puts userList.confirmed_at打印什么? -
hmm .. 当我以 user.confirmation_token 的身份循环遍历数组时,我实际上能够检索值。但它似乎仍然不是数组的一部分。更像是一种检索值的方法
