ContactsController＃new

Question

SyntaxError嗨，夥計們，我創建一個應用程序調用「應用程序」。到目前爲止，只有一個腳手架'聯繫人'，只需添加一個模型電話'地址'（地址有街道，城市，地區，郵政編碼，國家5屬性），一個聯繫人可以有一個或多個地址。所以這是我的工作。 的routes.rb

App::Application.routes.draw do 
    resources :contacts 
    resources :taggings 
    resources :addresses 
    root :to => 'Contacts#index' 
end 

模型/ contact.rb

class Contact < ActiveRecord::Base 
    attr_accessible :Email, :Firstname, :Lastname, :Mobilephone, 
    has_many :taggings, :dependent => :destroy 
    has_many :addresses, :through => :taggings 
    validates_presence_of :Firstname, :Lastname 
    attr_writer :address_street, :address_city, :address_region, :address_zipcode, :address_country 
    after_save :assign_street, :assign_city, :assign_region, :assign_zipcode, :assign_country 

    def address_streets 
    @address_streets || addresses.map(&street).join('') 
    end 

    def address_citys 
    @address_citys || addresses.map(&city).join('') 
    end 

    def address_regions 
    @address_regions || addresses.map(&region).join('') 
    end 

    def address_zipcode 
    @address_zipcodes || addresses.map(&zipcode).join('') 
    end 

    def address_countrys 
    @address_countrys || addresses.map(&country).join('') 
    end 



    def assign_streets 
    if @assign_streets 
     self.addresses = @assign_streets.split(/\s+/).map do |street| 
     Address.find_or_create_by_street(street) 
     end 
    end 
    end 

    def assign_citys 
    if @assign_citys 
     self.addresses = @assign_citys.split(/\s+/).map do |city| 
     Address.find_or_create_by_city(city) 
     end 
    end 
    end 

    def assign_regions 
    if @assign_regions 
     self.addresses = @assign_regions.split(/\s+/).map do |region| 
     Address.find_or_create_by_region(region) 
     end 
    end 
    end 

    def assign_zipcodes 
    if @assign_zipcodes 
     self.addresses = @assign_zipcodes.split(/\s+/).map do |zipcode| 
     Address.find_or_create_by_zipcode(zipcode) 
     end 
    end 
    end 

    def assign_countrys 
    if @assign_countrys 
     self.addresses = @assign_countrys.split(/\s+/).map do |country| 
     Address.find_or_create_by_country(country) 
     end 
    end 
    end 
end 

模型/ tagging.rb

class Tagging < ActiveRecord::Base 
    attr_accessible :Address_id, :Contact_id 
    belongs_to :contact 
    belongs_to :address 
end 

模型/ address.rb

class Address < ActiveRecord::Base 
    attr_accessible :City, :Country, :Region, :Street, :Zipcode 
    has_many :tagging, :dependent => :destroy 
    has_many :contact, :through => :taggings 
end 

視圖/接觸/_form.html.erb 停止工作，因爲我在下面添加!!代碼：

<form> 
    <p> 
    <%= f.label :street %><br /> 
    <%= f.text_field :address_street %> 
    </p> 
    </form> 

而且contact_controllor.rb我沒有碰過任何東西。當我開始我的服務器，並嘗試加載到「創建新的聯繫人」軌告訴我

SyntaxError in ContactsController#new 

/media/sf_VM_working/app/app/models/contact.rb:3: syntax error, unexpected tSYMBEG, expecting keyword_do or '{' or '(' 
    has_many :taggings, :dependent => :destroy 
      ^
/media/sf_VM_working/app/app/models/contact.rb:33: syntax error, unexpected keyword_do_block, expecting keyword_end 
     self.addresses = @assign_streets.split(/\s+/).map do |street| 
                 ^

     self.addresses = @assign_citys.split(/\s+/).map do |city| 
                 ^
/media/sf_VM_working/app/app/models/contact.rb:45: syntax error, unexpected keyword_end, expecting $end 

和

app/controllers/contacts_controller.rb:1:in `<top (required)>' 

可能有人幫我檢查哪裏出了問題，我不是一個好：」 （...謝謝

Answer 1

你對contact.rb 2線多了一個逗號 - 第一個錯誤信息告訴你這（因爲它發現，當它擊中3號線）：

個

/media/sf_VM_working/app/app/models/contact.rb:3：語法錯誤，意想不到tSYMBEG，keyword_do期待或 '{' 或 '（' 的has_many：的Tagging，：依賴=>：破壞

通過寫你的屬性小寫（:email, :firstname而不是:Email, :Firstname）
