如何將設計用戶連接到ProfilesController Ruby on Rails 4

Question

在開始之前，讓我說我有兩個不同的設計用戶模型。

我開始從scaffold_controller中刪除不必要的方法，因爲devise處理某些操作。

我試圖路由到current_user配置文件頁面，但每次嘗試在我的導航欄中添加鏈接時都會收到錯誤<％='我的配置文件'，current_user％>在這種情況下不起作用。我計劃在完成連接這些控制器後立即建立關聯。

class ProfilesController < ApplicationController 
    before_action :set_profile, only: [:show, :edit, :update, :destroy] 

    # GET /profiles 
    # GET /profiles.json 
    def index 
    @profiles = Profile.all 
    end 

    # GET /profiles/1 
    # GET /profiles/1.json 
    def show 
    @user = User.find(params[:id]) 

    respond_to do |format| 
     format.html 
     format.json {render :json => @user } 
    end 
    end 

    # GET /profiles/1/edit 
    def edit 
    end 

    # PATCH/PUT /profiles/1 
    # PATCH/PUT /profiles/1.json 
    def update 
    respond_to do |format| 
     if @profile.update(profile_params) 
     format.html { redirect_to @profile, notice: 'Profile was successfully updated.' } 
     format.json { render :show, status: :ok, location: @profile } 
     else 
     format.html { render :edit } 
     format.json { render json: @profile.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    # DELETE /profiles/1 
    # DELETE /profiles/1.json 
    def destroy 
    @profile.destroy 
    respond_to do |format| 
     format.html { redirect_to profiles_url, notice: 'Profile was successfully destroyed.' } 
     format.json { head :no_content } 
    end 
    end 

    private 
    # Use callbacks to share common setup or constraints between actions. 
    def set_profile 
     @profile = Profile.find(params[:id]) 
    end 

    # Never trust parameters from the scary internet, only allow the white list through. 
    def profile_params 
     params[:profile] 
    end 
end 
profiles GET /profiles(.:format)       profiles#index 
           POST /profiles(.:format)       profiles#create 
        new_profile GET /profiles/new(.:format)      profiles#new 
       edit_profile GET /profiles/:id/edit(.:format)     profiles#edit 
         profile GET /profiles/:id(.:format)      profiles#show 
           PATCH /profiles/:id(.:format)      profiles#update 
           PUT /profiles/:id(.:format)      profiles#update 
           DELETE /profiles/:id(.:format)      profiles#destroy

假設（如壞事做），你已經創建配置文件在創建用戶（因爲沒有創建控制器動作）和一個配置文件belongs_to的用戶，那麼這應該工作：

<%= link_to "My Profile", current_user.profile %> 

一般來說，我會得到我的協會建立正確我連看控制器之前。
