Rails教程(Hartl)v3.2中的错误

我在第8章,所有测试都在练习前正确传递。除了两个问题(我认为它们是相关的)。

下拉菜单未使用引导程序触发,因为会话销毁路径似乎不正确。我也试图使用form_tag代替form_for标记,我不断收到以下错误:

undefined method `[]' for nil:NilClass

以下是app / views / sessions下的new_html.erb:

<% provide(:title, "Sign in") %>
<h1>Sign in</h1>

<div class="row">
  <div class="span6 offset3">
    <%= form_tag sessions_path do %>

      <%= label_tag :email %>
      <%= text_field_tag :email %>

      <%= label_tag :password %>
      <%= password_field_tag :password %>

      <%= submit_tag "Sign in", :class => "btn btn-large btn-primary" %>
    <% end %>

    <p>New user? <%= link_to "Sign up now!", signup_path %></p>
  </div>
</div>

这是sessions_controller.rb:

class SessionsController < ApplicationController

  def new
  end

  def create
    user = User.find_by_email(params[:session][:email])
    if user && user.authenticate(params[:session][:password])
      sign_in user
      redirect_to user
    else
      flash.now[:error] = 'Invalid email/password combination' # Not quite right!
      render 'new'
    end
  end

  def destroy
    sign_out
    redirect_to root_path
  end
end

最后,这是rake路线输出:

      users GET    /users(.:format)          users#index
            POST   /users(.:format)          users#create
   new_user GET    /users/new(.:format)      users#new
  edit_user GET    /users/:id/edit(.:format) users#edit
       user GET    /users/:id(.:format)      users#show
            PUT    /users/:id(.:format)      users#update
            DELETE /users/:id(.:format)      users#destroy
   sessions POST   /sessions(.:format)       sessions#create
new_session GET    /sessions/new(.:format)   sessions#new
    session DELETE /sessions/:id(.:format)   sessions#destroy
     signup        /signup(.:format)         users#new
     signin        /signin(.:format)         sessions#new
    signout DELETE /signout(.:format)        sessions#destroy
       help        /help(.:format)           static_pages#help
      about        /about(.:format)          static_pages#about
    contact        /contact(.:format)        static_pages#contact
       root        /                         static_pages#home

任何帮助都会很棒。

编辑:

cbright得到了它。我不得不修改sessions_controller。以下两行按预期工作。

user = User.find_by_email(params[:email])
if user && user.authenticate(params[:password])

答案 0 :(得分:4)

不再使用与form_for一起使用的会话符号,因此将params [:session] [:email]和params [:session] [:password]替换为params [:email] params [:password]。
