Question

我正在创建一个项目，允许用户在登录后登录并引用其他用户。用户拥有多个推荐人和推荐人belongs_to用户。我想有一个页面，一旦当前用户登录，他们可以使用params：name和referral_email输入推荐。但这是一个协作项目，设置用户身份验证的人使用设计。目前，我收到以下错误：

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

用户控制器：

class UsersController < ApplicationController
  def new
  end

端

推荐控制器：

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

用户模型：

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

推荐模式

class Referral < ActiveRecord::Base
    belongs_to :user
end

用户视图：

<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" %>

推介视图：

<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 %>

路线：

  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

Answer 1

问题来自推介视图中的devise_error_messages! - 将其删除。只有user资源被设置为与设计一起使用，没有别的。

正如评论中所述，您应该重新考虑将推介作为用户下的嵌套资源 - 使用它的方式确实没有任何优势，并且有很多错误的余地。保持简单！

创建belongs_to和has_many路由，控制器和视图？
