創建belongs_to和has_many路由，控制器和視圖？

Question

我正在創建一個項目，允許用戶在登錄後引用其他用戶。用戶擁有_many引薦和引薦belongs_to用戶。我想要一個頁面，一旦當前用戶登錄，他們就可以輸入參數：名稱和referral_email。但是這是一個合作項目，並且設置用戶認證的人使用了設計。目前，我發現了以下錯誤：

undefined method `resource' for #<ReferralsController:0x007fb75735aa00> 

用戶控制器：

class UsersController < ApplicationController 
    def new 
    end 

末

推薦控制器：

class ReferralsController < ApplicationController 

def new 
    @referral = Referral.new 
end 

def create 

    @referral = current_user.referrals.new(referral_params) 

    if @referral.save 
     redirect_to @referral 
    else 
     render 'new' 
    end 
end 

def show 
    @referrals = current_user.find_by_user_id(params[:user_id]).referrals.all 
end 

def index 
    @referrals = current_user.referrals.all 
end 

def edit 
    @referral = Referral.find(params[:id]) 
end 

def update 
    @referral = Referral.find(params[:id]) 

    if @referral.update(referral_params) 
    redirect_to @referral 
    else 
    render 'edit' 
    end 
end 

def destroy 
    @referral = Referral.find(params[:id]) 
    @referral.destroy 

    redirect_to referral_path 
end 

private 
    def referral_params 
    params.require(:referral).permit(:name, :email, :user_id) 
    end 

end 

用戶模型：

class User < ActiveRecord::Base 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
     has_many :referrals 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 

    include RoleModel 

# attr_accessible :email, :password, :password_confirmation, :school_name, :sport, :roles, :roles_mask 

    roles_attribute :roles_mask 

    roles :admin, :coach, :guest 



end 

推薦型號

class Referral < ActiveRecord::Base 
    belongs_to :user 
end 

用戶視圖：

<h2>Sign up</h2> 

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %> 
    <%= devise_error_messages! %> 

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

    <div><%= f.label :school_name %><br /> 
    <%= f.text_field :school_name %></div> 

    <div><%= f.label :sport %><br /> 
    <%= f.text_field :sport %></div> 

    <div><%= f.label :password %><br /> 
    <%= f.password_field :password, autocomplete: "off" %></div> 

    <div><%= f.label :password_confirmation %><br /> 
    <%= f.password_field :password_confirmation, autocomplete: "off" %></div> 

    <div><%= f.submit "Sign up" %></div> 
<% end %> 

<%= render "devise/shared/links" %> 

推薦視圖：

<h2>Refer a coach </h2> 

<%= form_for ([current_user, @referral]), :html => { :mulitpart => true } do |f| %> 

    <%= devise_error_messages! %> 

    <div><%= f.label :referral %><br /> 
    <%= f.text_field :referral %></div> 

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


    <div><%= f.submit "Refer This Coach" %></div> 
<% end %> 

途徑：

Blog::Application.routes.draw do 

    devise_for :users 

    resources :users do 
     resources :referrals 
    end 

    get 'sessions/new' 

    get 'users/new' 




    resources :articles do 
    resources :comments 
    end 

    root 'welcome#index' 
end

問題是在t來他在您的推介視圖中devise_error_messages! - 將其刪除。只有user資源被設置爲與設計一起工作，沒有別的。

正如評論中所述，您應該重新考慮引薦是用戶下的嵌套資源 - 您使用它的方式並沒有真正的優勢，並且有很大的出錯空間。把事情簡單化！
