Ruby on rails 设计可确认：令牌无效错误

已经找了3个小时了。。。建立可证实的电子邮件，它被认为是容易的，但它远远不是。不管怎么说，我已经克服了大量的错误、未定义的方法和变量，并努力通过这件事来给我一些东西。。。但是我不能证实。我在确认控制器的引擎盖下查看了一下，但没有结果。。。这根本不符合事实。我不知道我在这里做错了什么，但它始终将我重定向到“重新发送确认说明”页面

更新：获取了在其初始位置生成的错误，即臭名昭著的无效令牌错误。又一次，一个小时的研究没有解决任何问题，我一直听说你需要使用@token，就像我认为的那样。。。它本应该让它发挥作用，但事实并非如此

控制器：默认设计确认控制器：

    class  ConfirmationsController < Devise::ConfirmationsController
  # GET /resource/confirmation/new
  def new
    self.resource = resource_class.new
  end

  # POST /resource/confirmation
  def create
    self.resource = resource_class.send_confirmation_instructions(resource_params)
    yield resource if block_given?

    if successfully_sent?(resource)
      respond_with({}, location: after_resending_confirmation_instructions_path_for(resource_name))
    else
      respond_with(resource)
    end
  end

  # GET /resource/confirmation?confirmation_token=abcdef
  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])
    yield resource if block_given?

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_flashing_format?
      respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource) }
    else
      respond_with_navigational(resource.errors, status: :unprocessable_entity){ render :new }
    end
  end

  protected

    # The path used after resending confirmation instructions.
    def after_resending_confirmation_instructions_path_for(resource_name)
      new_session_path(resource_name) if is_navigational_format?
    end

    # The path used after confirmation.
    def after_confirmation_path_for(resource_name, resource)
      if signed_in?(resource_name)
        authenticated_root_path(resource)
      else
        unauthenticated_root_path
      end
    end

end

# GET /resource/confirmation?confirmation_token=abcdef
  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])
    yield resource if block_given?

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_flashing_format?
      respond_to do |format|
        format.html{redirect_to unauthenticated_root_path}
        format.mobile {redirect_to unauthenticated_root_path, notice: 'Confirmation success!'}
      end   
    else
      respond_to do |format|
        format.html{render :new}
        format.mobile {redirect_to unauthenticated_root_path, alert: 'Failure, already confirmed'}
      end
    end
  end

新确认书

<h2>Resend confirmation instructions</h2>

<%= form_for(resource, as: resource_name, url: confirmation_path(resource_name), html: { method: :post }) do |f| %>

  <div><%= f.label :email %><br />
  <%= f.email_field :email, autofocus: true %></div>

  <div><%= f.submit "Resend confirmation instructions" %></div>
<% end %>
<%= devise_error_messages!(:email) %>
<%= render "devise/shared/links" %>

重新发送确认指令

此外，我还修改了Desive error helper，使其显示自定义错误（不知道可能是什么把它搞砸了，但它在这里：

module DeviseHelper
  def devise_error_messages!(field)
    return nil if resource.errors.empty?
    messages = resource.errors.full_messages_for(field).map { |msg| content_tag(:li, msg) }.join
    if resource.errors.full_messages_for(field) != []
      html = <<-HTML
    <div class="alert alert-error alert-block"> <button type="button"
    class="close" data-dismiss="alert">x</button>
      #{messages}
    </div>
    HTML

    html.html_safe
    else
      return nil
    end
  end

end

def设计错误消息！（字段）
如果resource.errors.empty返回nil？
messages=resource.errors.full_messages_for（field）.map{{| msg | content_tag（：li，msg）}.join
if resource.errors.full_messages_for（字段）！=[]
html=好的，经过10个小时的战斗后，我决定从头开始重新启动，并在本地和heroku上都能运行。遵循Rails 4的这个tut，设计3.2.4:。然后我有一段时间没有定义路由器错误，所以我查看了registrations控制器，并替换了默认版本中的6或7行墨迹到另一个图坦卡蒙，更好地解释了这一点：

注册控制器操作（工作）

维奥拉！它顺利通过了。所以只要花5分钟的事情只花了我10个小时。这就是效率

我还将其用于移动格式，以防你们中的一些人遇到问题：

确认控制员：

    class  ConfirmationsController < Devise::ConfirmationsController
  # GET /resource/confirmation/new
  def new
    self.resource = resource_class.new
  end

  # POST /resource/confirmation
  def create
    self.resource = resource_class.send_confirmation_instructions(resource_params)
    yield resource if block_given?

    if successfully_sent?(resource)
      respond_with({}, location: after_resending_confirmation_instructions_path_for(resource_name))
    else
      respond_with(resource)
    end
  end

  # GET /resource/confirmation?confirmation_token=abcdef
  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])
    yield resource if block_given?

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_flashing_format?
      respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource) }
    else
      respond_with_navigational(resource.errors, status: :unprocessable_entity){ render :new }
    end
  end

  protected

    # The path used after resending confirmation instructions.
    def after_resending_confirmation_instructions_path_for(resource_name)
      new_session_path(resource_name) if is_navigational_format?
    end

    # The path used after confirmation.
    def after_confirmation_path_for(resource_name, resource)
      if signed_in?(resource_name)
        authenticated_root_path(resource)
      else
        unauthenticated_root_path
      end
    end

end

# GET /resource/confirmation?confirmation_token=abcdef
  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])
    yield resource if block_given?

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_flashing_format?
      respond_to do |format|
        format.html{redirect_to unauthenticated_root_path}
        format.mobile {redirect_to unauthenticated_root_path, notice: 'Confirmation success!'}
      end   
    else
      respond_to do |format|
        format.html{render :new}
        format.mobile {redirect_to unauthenticated_root_path, alert: 'Failure, already confirmed'}
      end
    end
  end

如果你有更技术上正确的答案张贴，我会接受它，如果它比我的好

# GET /resource/confirmation?confirmation_token=abcdef
  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])
    yield resource if block_given?

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_flashing_format?
      respond_to do |format|
        format.html{redirect_to unauthenticated_root_path}
        format.mobile {redirect_to unauthenticated_root_path, notice: 'Confirmation success!'}
      end   
    else
      respond_to do |format|
        format.html{render :new}
        format.mobile {redirect_to unauthenticated_root_path, alert: 'Failure, already confirmed'}
      end
    end
  end
