ruby-on-rails-3 - 仅在Heroku上完成302在Rails 3中的注册过程

Question

在我的Rails 3应用程序中，由于某种原因，我在注册过程中收到302。具体来说，当我从创建新用户重定向到编辑其个人资料时，我从应用程序重定向到/login。这仅在Heroku上发生。如果我在本地运行该应用程序，则它将正常运行。

这是我的heroku logs：

在我的 users_controller.rb中：

def create
  @user = User.new(params[:user])
  if @user.save
    session[:user_id] = @user.id
    redirect_to join_path, :notice => 'User successfully added.'
    UserMailer.registration_confirmation(@user).deliver
  else
    render :action => 'new'
  end
end

在我的 routes.rb中：

match "/signup/join" => "profiles#edit", :as => 'join'

因此，如果查看日志，我将向 POST提交 /users，发送电子邮件，并重定向到 edit中的 profiles_controller.rb操作。因此，似乎一切都应该正确，但我正在重定向。有人也发生过这种情况吗？

更新：在我的 profiles_controller.rb中：

class ProfilesController < ApplicationController
  before_filter :authenticate, :only => [:edit, :update]
  layout "application", :except => [:edit, :show]

  def user
    @user = current_user
  end

  def edit
    @profile = user.profile
    render :layout => "join_form"
  end

在我的 sessions_controller.rb中：

class SessionsController < ApplicationController  
  def new
  end

  def create
    if user = User.authenticate(params[:email].downcase, params[:password])
      session[:user_id] = user.id
      cookies.permanent[:auth_token] = user.auth_token
      if user.profile.higher_ed?
        redirect_to user.profile, :notice => "Logged in successfully"
      else
        redirect_to join_path, :notice => "Logged in successfully"
      end
    else
      flash.now[:alert] = "Invalid login/password. Try again!"
      render :action => 'new'
    end
  end

gem "aws-s3", :require => "aws/s3"

正如@phoet上面建议的那样，我开始删除可能导致问题的代码，并且出现无方法错误，这导致我找到了解决方案。我必须重新编写current_user方法中的逻辑。我将其更改为：

def current_user
  return unless session[:user_id]
  @current_user ||= User.find_by_id(session[:user_id])
  @current_user ||= User.find_by_auth_token!(cookies[:auth_token]) if cookies[:auth_token]
end    

至：

def current_user
  @current_user ||= lookup_user
end

def lookup_user
  if cookies[:auth_token]
    User.find_by_auth_token!(cookies[:auth_token])
  elsif session[:user_id]
    User.find_by_id(session[:user_id])
  end
end
