Webrat select_date 选择器失败

Question

步骤文件中的代码：

  select_date user.date_of_birth, :from => "Date of birth"

选择器失败

When I register with valid user credentials # features/step_definitions/authentication_steps.rb:2
  Could not find field: "user_date_of_birth_1i_1i" (Webrat::NotFoundError)
  ./features/step_definitions/authentication_steps.rb:9:in `/^I register with valid user credentials$/'
  features/authentication.feature:6:in `When I register with valid user credentials'

HTML 输出似乎很正常：

这是错误，还是我正在做的有事吗

Answer 1

使用“id_prefix”参数解决了

  select_date user.date_of_birth, :id_prefix => "user_date_of_birth"

但这似乎是 Webrat 的错误。
