Question

我有一个应用程序，其中： 1.用户在查看其个人资料信息的页面上 2.用户按下按钮，通过此页面向某人发送电子邮件 3.在发送电子邮件之后，用户将被再次发送回查看他们的个人资料信息，并且会发出通知，告诉他们电子邮件是否有效。

我没有。 3.我不确定如何设置重定向（或其他适当的选项），以便用户再次查看其个人资料信息

控制器：

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

  # 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 = Profile.new
  end

  # GET /profiles/1/edit
  def edit
    @profile = Profile.find_by user_id: current_user.id
  end

  # POST /profiles
  # POST /profiles.json
  def create
    @profile = Profile.new(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

  def email_profile
    destination = params[:to]
    share = Share.profile(@profile, destination)
    if destination =~ /@/ && share.deliver
      redirect_to @profile, notice: 'email sent'
    else 
      redirect_to @profile, notice: 'email failed'
    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.require(:profile).permit(:user_id, :first_name, :last_name, :dob, :email, :mobile, :address, :suburb, :postcode, :city, :state, :country)
    end
end

分享梅勒：

  class Share < ActionMailer::Base
    default_url_options[:host] = "localhost:3000"
  default from: "from@example.com"

  def profile(profile, destination)
   @profile = profile
   mail(to: destination, subject: "sent you stuff")
  end
end

当前错误：

ActionController::ActionControllerError in ProfilesController#email_profile
Cannot redirect to nil!

我认为它与发送电子邮件后没有传递的id参数有关...但我是新手，所以我真的不知道我在说什么..感谢任何指导所以我可以解决这个问题并且更好地理解ROR：）

您可能需要先找到@profile。我猜想Profile.find(params[:profile_id])之类的东西不见了。

无法重定向到零！ ActionController的:: ActionControllerError
