未定义的方法`signup_path'的邀请（仍不能发送测试邀请）

对于最后的日子，我想申请一个测试邀请系统。我遵循了第124课的铁路课。我为我的用户定制了它。未定义的方法`signup_path'的邀请（仍不能发送测试邀请）

我的routes.rb

resources :invitations, only: [:new, :create] 
match '/signup/:invitation_token', to: 'users#new'

邀请型号：

class Invitation < ActiveRecord::Base 
    attr_accessible :new, :recipient_email, :user_id, :sent_at, :token 

    belongs_to :user 
    has_one :recipient, :class_name => 'User' 

    validates_presence_of :recipient_email 
    validate :recipient_is_not_registered 
    validate :user_has_invitations, :if => :user 

    before_create :generate_token 
    before_create :decrement_user_count, :if => :user 

    private 

    def recipient_is_not_registered 
     errors.add :recipient_email, 'zaten siteye üye' if User.find_by_email(recipient_email) 
    end 

    def user_has_invitations 
     unless user.invitation_limit > 0 
      errors.add_to_base 'Siteye davetiyeniz kalmamıştır.' 
     end 
    end 

    def generate_token 
     self.token = Digest::SHA1.hexdigest([Time.now, rand].join) 
    end 

    def decrement_user_count 
     user.decrement! :invitation_limit 
    end 
end

Invitations_controller：

class InvitationsController < ApplicationController 
    def new 
     @invitation = Invitation.new 
    end 

    def create 
     @invitation = Invitation.new(params[:invitation]) 
     @invitation.user = current_user 
     if @invitation.save 
      if signed_in? 
       Mailer.deliver_invitation(@invitation, signup_path(@invitation.token)) 
       flash[:notice] = "Teşekkürler,davetiniz gönderildi." 
       redirect_to root_path 
      else 
       flash[:notice] = "Teşekkürler,sizi almaya hazır olduğumuzda bildireceğiz." 
       redirect_to root_path 
      end 
     else 
    render :action => 'new' 
     end 
    end 
end

。这是我mailer.rb：

def invitation(invitation, signup_url) 
    subject 'Siteye Davet' 
    recipients invitation.recipient_email 
    from  'fo[email protected]' 
    body  :invitation => invitation, :signup_url => signup_path 
    invitation.update_attribute(:sent_at, Time.now) 
end

当我发出了邀请，我的日志文件显示：

INSERT INTO "invitations" ("created_at", "recipient_email", "sent_at", "token", "updated_at", "user_id") VALUES (?, ?, ?, ?, ?, ?) [["created_at", Wed, 04 Jul 2012 21:55:13 UTC +00:00], ["recipient_email", "[email protected]"], ["sent_at", nil], ["token", "c29e2dcc22c033a1e975f5755795db9f2a8fd5c2"], ["updated_at", Wed, 04 Jul 2012 21:55:13 UTC +00:00], ["user_id", 1]] 
    (131.3ms) commit transaction 
Completed 500 Internal Server Error in 208ms 

NoMethodError (undefined method `signup_path' for #<InvitationsController:0x000000044ef508>):

我能理解我必须改变SIGNUP_URL的。但我无法找到正确的方法。如何修复邀请创建操作？

我没有看到signup_path实际定义在任何地方，你是否错过了一些你可以添加到问题的来源？ – MBHNYC

你需要在你的routes.rb改变match声明如下：

match '/signup/:invitation_token', to: 'users#new', as: 'signup'

这将通知Rails的是signup_path是链接到/signup/:invitation_token匹配的路径名。

我改变了我的路线。下面粘贴了我的调试器。 – ytsejam

如果这是您的问题的正确答案，则应将其标记为正确答案。如果它导致了另一个问题，你应该单独发布这个新问题，以便更多的人会看到它/有可能回答它。 – Veraticus

不，我不能发送邀请。 – ytsejam
