Devise and Rails - ArgumentError trong Devise :: RegistrationsController # create

Question

Khi người dùng mới gửi biểu mẫu đăng ký người dùng mới, họ nhận được thông báo lỗi dưới đây. Tôi nghi ngờ nó vì devise/registrations_controller.rb không tồn tại.

Tôi có cần phải tạo cấu trúc thư mục và bộ điều khiển này hay tôi có thể sửa đổi tuyến đường.rb để tránh tìm kiếm bộ điều khiển không tồn tại?

Lỗi:

ArgumentError in Devise::RegistrationsController#create 

wrong number of arguments (0 for 1) 
Rails.root: C:/Users/COMPAQ/Documents/NetBeansProjects/RailsBlog 

Parameters: 

{"utf8"=>"✓",

    "user"=>{"email"=>"foo@bar.com", 
    "password"=>"[FILTERED]",

Answer 1

Devise::RegistrationsController tồn tại within the Devise gem, vì vậy bạn không cần phải tạo.

Cập nhật: Lỗi xảy ra vì bạn đang sử dụng has_secure_password, là giải pháp xác thực tự chế. Bạn không cần nó với Devise (nó xử lý việc mã hóa mật khẩu của chính nó). Loại bỏ dòng đó!

Lý do khiến ứng dụng của bạn phát nổ là mong đợi password_digest là thuộc tính trên mô hình của bạn và validates its presence. Khi nó xác nhận, nó cố gắng đọc thuộc tính, nhưng thay vào đó nó là phương thức password_digest của Devise (dự kiến ​​nhận mật khẩu như một đối số, vì vậy hãy tăng ArgumentError khi nó không nhận được).
