Rails在使用Devise注册后发布多步表单数据

Question

我有一个两步形式，可以在会话中保存数据，并在用户登录时创建新记录。

如果新用户尚未注册，我希望他能够：

1. 填写表格＃1
2. 填写表格＃2
3. 重定向到设计注册（new_registration_path）
4. 在注册/登录完成后从表单数据发布/创建记录

请参阅下面的代码（ location_controller.rb ）：

开：“elsif @location.last_step？”，如果用户未登录但在登录后未保存数据，则会指示注册。

有没有办法传递会话表单数据思想设计，以便在注册后发布/创建记录？

def new
  session[:location_params] ||= {}
    if current_user.nil?
      @location = Location.new(session[:location_params])
    else
      @location = current_user.locations.new(session[:location_params])
    end

  @location.current_step = session[:location_step]

  respond_to do |format|
    format.html # new.html.erb
    format.json { render json: @location }
  end   
end

def create
    session[:location_params].deep_merge!(params[:location]) if params[:location]
    if current_user.nil?
      @location = Location.new(session[:location_params])
    else
      @location = current_user.locations.new(session[:location_params])
    end
    @location.current_step = session[:location_step]
    if @location.valid?   
      if params[:back_button]
        @location.previous_step
      elsif @location.last_step?
       @location.save
      else
        @location.next_step
      end
      session[:location_step] = @location.current_step
    end

    if @location.new_record?
      render "new"
    else
      session[:location_step] = session[:location_params] = nil
      flash[:notice] = "Trip saved!"
      redirect_to @location
    end
  end

我解决了它：

1. 在locations.rb
中添加了store_form_data(@location) Session中的
2. store_form_data函数（见下文）
3. 将include SessionsHelper添加到a​​pplication_controller.rb
4. 在application_controller.rb中添加了def after_sign_in_path_for(resource)函数（请参阅打击）

应用程序/助手/ session_helper.rb：

module SessionsHelper
  def store_form_data(locations)
    session[:form_data] = locations
  end
end

应用程序/控制器/ application_controller.rb：

class ApplicationController < ActionController::Base
  protect_from_forgery
  include SessionsHelper

  def after_sign_in_path_for(resource)
    if session[:form_data].present?
      @user = current_user
      @location = session[:form_data]
      @user.locations << @location
      session[:form_data] = nil
      flash[:notice] = 'Trip saved!'
      index_path
    else
      new_location_path
    end
  end
end

应用/控制器/ locations_controller.rb：

 def new
    #@location = Location.new
    session[:location_params] ||= {}
    session[:form_data] = nil
    if current_user.nil?
      @location = Location.new(session[:location_params])
    else
      @location = current_user.locations.new(session[:location_params])
    end

    @location.current_step = session[:location_step]

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @location }
    end
  end

def create
    session[:location_params].deep_merge!(params[:location]) if params[:location]
    if current_user.nil?
      @location = Location.new(session[:location_params])
    else
      @location = current_user.locations.new(session[:location_params])
    end
    @location.current_step = session[:location_step]
    if @location.valid?   
      if params[:back_button]
        @location.previous_step
      elsif @location.last_step?
        if current_user.nil?
          store_form_data(@location)
        end
       @location.save
      else
        @location.next_step
      end
      session[:location_step] = @location.current_step
    end

    if @location.new_record?
      render "new"
    else
      session[:location_step] = session[:location_params] = nil
      flash[:notice] = "Trip saved!"
      redirect_to @location
    end
  end
