使用 Ember-data 和 Rails 编辑模型未保存

Question

我正在尝试使用 ember-data 和 rails 编辑用户，当我编辑用户信息并尝试执行 model.save() 时，我得到

unexpected end of input

我的控制台出错。 Rails 端似乎正在进行一个奇怪的查询。这是来自 Rails 的查询：

Started PUT "/users/2" for ::1 at 2015-04-11 15:59:17 -0500
 Processing by UsersController#update as HTML
 Parameters: {"user"=>{"username"=>"adminUser", "email"=>"admin@test.com", "password"=>"[FILTERED]", "admin"=>true}, "id"=>"2"}
 User Load (0.3ms)  SELECT  "users".* FROM "users" WHERE "users"."id" =  LIMIT 1  [["id", 2]]
 ApiKey Load (0.4ms)  SELECT  "api_keys".* FROM "api_keys" WHERE (expired_at >= '2015-04-11 20:59:17.113883') AND "api_keys"."access_token" =   ORDER BY "api_keys"."id" ASC LIMIT 1  [["access_token", "500b9b5d38ecb9f851b89823d5b40d0f"]]

 User Load (0.3ms)  SELECT  "users".* FROM "users" WHERE "users"."id" =  LIMIT 1  [["id", 2]]

 ApiKey Load (0.4ms)  SELECT  "api_keys".* FROM "api_keys" WHERE "api_keys"."user_id" =  AND (expired_at >= '2015-04-11 20:59:17.117827')  ORDER BY "api_keys"."id" ASC LIMIT 1  [["user_id", 2]]
 (0.2ms)  BEGIN
 User Exists (0.6ms)  SELECT  1 AS one FROM "users" WHERE (LOWER("users"."username") = LOWER('adminUser') AND "users"."id" != 2) LIMIT 1
 User Exists (0.3ms)  SELECT  1 AS one FROM "users" WHERE (LOWER("users"."email") = LOWER('admin@test.com') AND "users"."id" != 2) LIMIT 1
 (0.2ms)  ROLLBACK

我不明白为什么 Rails 会像这样 select !=2。

Answer 1

有验证失败。您正在更新 ID 为 2 的用户，我敢打赌您对 username 和 email 进行了唯一性验证。问题是有另一个 User 记录至少具有相同的电子邮件地址，这导致回滚。

您可能还应该确保在更新失败时返回状态 422 (Unprocessable Entity) 并显示适当的错误。
