Heroku [警告]您提供了devise_for：用户，但在您的应用程序中没有定义用户定义的模型 [英] Heroku [WARNING] You provided devise_for :users but there is no model User defined in your application

问题描述

我有一台Rails 3（3.0.9）应用程序，可以在我的电脑上完美运行Ruby 1.9.7和gem devise（1.4.2）。

我试图在heroku上推送它，并在应用程序加载时收到以下错误消息：

  [警告]您提供了devise_for：users但没有模型用户在您的应用程序中定义

问题来自设计，但我不知道如何解决它。
我的模型用户被正确定义，并且它可以在我的电脑上运行...
有人知道如何解决这个问题吗？

感谢你帮助

解决方案

请确保您有这个：

  class User< ActiveRecord :: Base 
  

定义在用户/设计模型的顶部。

此外，请确保您运行迁移。

  heroku rake db：migrate 
  

在控制台中。

I have an rails 3 (3.0.9) application working on ruby 1.8.7 with the gem devise (1.4.2) on my computer working perfectly.

I tried to push it on heroku and i got the following error message on application load:

[WARNING] You provided devise_for :users but there is no model User defined in your application
=> Booting WEBrick
=> Rails 3.0.9 application starting in production on http://0.0.0.0:43292

    from /app/vendor/bundle/ruby/1.9.1/gems/devise-1.4.2/lib/devise.rb:409:in `configure_warden!'

The problem comes from devise but i don't know how to fix it. My model User is correctly defined, and it works on my computer... Does anyone know how to fix this ?

Thanks for you help

解决方案

Make sure you have this:

class User < ActiveRecord::Base

Defined at the top of your user/devise model.

ALso, make sure you run your migrations.

heroku rake db:migrate

In console.
