Question

我有一个rails 4应用程序，我希望某些书籍需要一个密码才能看到。

我有一个名为Book.rb的模型：

class Book < ActiveRecord::Base
   has_secure_password :validations => false
end

以及具有以下形式的sign_in.html.haml：

= form_for login_book_path do |f| 
   = f.password_field :password
   = f.submit "View Book"

并且登录簿路径路由到以下控制器方法：

def book_login
  @book = Book.find_by(slug: params[:slug])
  respond_to do |format|
     if @book.authenticate(params[:password])
        format.html { redirect_to root_path }
     else
        format.html { render :sign_in }
     end
  end
end

如果我对密码进行硬编码（例如@book.authenticate("thesecretpassword")），它会正确地将我重定向到root_url。但出于某种原因，如果没有硬编码，它就不起作用（只是将我发回给sign_in.html.haml？

当我点击＆＃34; VIEW BOOK＆＃34;时，终端输出到了终端。按钮：
