heroku 不更新数据库架构
当我部署时，Heroku 似乎没有更新我的数据库架构。以下是详细信息：
这是 User 类应该是什么样子的：
create_table "users", :force => true do |t|
t.string "username"
t.datetime "created_at"
t.datetime "updated_at"
t.string "email"
t.string "encrypted_password"
t.string "salt"
t.string "remember_token"
t.boolean "admin", :default => false
end
这是我的部署过程：
git push heroku master
heroku rake db:migrate
heroku db:push
一切似乎都很顺利......除了如果我检查数据库中的实际 User 表......
heroku console User
我获取旧版本的用户...
User(id: integer, username: string, created_at: datetime, updated_at: datetime)
知道我做错了什么吗？ 非常感谢您的帮助！

Heroku doesn't seem to update my database schema when I deploy. Here are the details:
Here is what is should look like for the User class:
create_table "users", :force => true do |t|
t.string "username"
t.datetime "created_at"
t.datetime "updated_at"
t.string "email"
t.string "encrypted_password"
t.string "salt"
t.string "remember_token"
t.boolean "admin", :default => false
end
Here is my deploy procedure:
git push heroku master
heroku rake db:migrate
heroku db:push
Everything seems to go smoothly... except that if I check the actually User table in db...
heroku console User
... I get an old version of User...
User(id: integer, username: string, created_at: datetime, updated_at: datetime)
Any idea what I am doing wrong?
Thanks a lot for your help!

当您
heroku rake db:migrate时，您看到任何输出吗？迁移后尝试运行
heroku restart以重新启动 Web 服务器和 DJ Worker。这不应该影响您的控制台，但我已经看到 Web 服务器在部署后立即提供旧版本的代码，这通常不是问题，但对于挂起的迁移可能会出现问题。Do you see any output when you
heroku rake db:migrate?Try running
heroku restartafter you migrate to restart the web servers and DJ workers. That shouldn't influence your console, but I have seen web servers serving old versions of the code immediately after a deploy, which normally isn't a problem but with pending migrations can be.你可能想尝试
希望这有帮助。
You might want to try
Hope this helps.
接受的答案是正确的。仅供参考，您现在使用
heroku run rake db:migrate因为heroku rake db:migrate已弃用The accepted answer is right. FYI though, you now use
heroku run rake db:migratebecauseheroku rake db:migrateis deprecated运行heroku rake run db:migrate
然后
heroku restart刷新您的网页，它应该可以正常工作。
Run
heroku rake run db:migrateThen
heroku restartRefresh your web page and it should all work.
