Question

我使用设计和user模型创建了profile模型，一切正常。我试图为用户创建一个链接，以便能够转到他的个人资料并编辑个人资料

<li><%= link_to "Profile", edit_profile_path(current_user) %></li>

我收到错误：ActiveRecord::RecordNotFound in ProfilesController#show

用户has_one :profile，所有关联都已正确关联，并且user_id模型中的profile列正在按预期保存数据。

它告诉我错误在这里：

    def set_profile
      @profile = Profile.find(params[:id])
    end

我一直试图解决这个问题，但没有运气？

profile_controller.rb：

class ProfilesController < ApplicationController
  before_action :set_profile, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, only: [:show, :new, :edit, :create, :update, :destroy]

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

  # GET /profiles/1
  # GET /profiles/1.json
  def show
  end

  # GET /profiles/new
  def new
    @profile = current_user.build_profile
  end

  # GET /profiles/1/edit
  def edit

  end

  # POST /profiles
  # POST /profiles.json
  def create
    @profile = current_user.build_profile(profile_params)

    respond_to do |format|
      if @profile.save
        format.html { redirect_to @profile, notice: 'Profile was successfully created.' }
        format.json { render :show, status: :created, location: @profile }
      else
        format.html { render :new }
        format.json { render json: @profile.errors, status: :unprocessable_entity }
      end
    end
  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_by(user_id: params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def profile_params
      params.require(:profile).permit(:bio, :user_id, educations_attributes: [:id, :university, :course, :yearCompleted, :_destroy])
    end
end

路线：

  resources :profiles
  devise_for :users, controllers: {registrations: "registrations"}
  get 'home/index'
  root 'home#index'

已更新

我改变了：

def set_profile
  @profile = Profile.find(params[:id])
end

要

def set_profile
  @profile = Profile.find_by(user_id: params[:id])
end

将我带到用户的正确编辑视图，但是当我点击更新时，它会抛出一个错误：未定义的方法`update＆＃39;为零：NilClass

使用时

edit_profile_path(current_user)

params [：id]是current_users id。尝试像

这样的东西

@profile = Profile.find_by(user_id: params[:id])

更新

对用户个人资料使用单一资源可能更有意义。您可以在Rails指南中阅读有关单一资源的更多信息：http://guides.rubyonrails.org/routing.html#singular-resources

路由文件：

ressource :profile

简化控制器：

class ProfilesController < ApplicationController
  before_action :authenticate_user!
  before_action :load_profile

  def show; end

  def edit; end

  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

  private

    def load_profile
      @profile = current_user.profile || current_user.build_profile
    end

    def profile_params
      params.require(:profile).permit(:bio, :user_id, educations_attributes: [:id, :university, :course, :yearCompleted, :_destroy])
    end
end

编辑个人资料页面的示例链接：<li><%= link_to "Profile", edit_profile_path %></li>

无法找到id =的个人资料
