rails应用程序中的架构文件不会再更新

Question

我一直在运行一些迁移，它不更新架构文件。我知道迁移已经正确地改变了我的数据库，但似乎我的模式文件不会改变了......这是我的模式文件。它错过了我创建的最后一个表（表'通知'）以及我在此表上运行的多个迁移。

    add_foreign_key "subscriptions", "tournaments" 
    add_foreign_key "subscriptions", "users" 
    add_foreign_key "tournaments", "users" 
end 

然后我运行rake db：drop db：create db：migrate但我的模式文件仍然不完整。然后我试图运行另一迁移只是为了检查：

class AddColumnClubToUsers < ActiveRecord::Migration 
    def change 
    add_column :users, :club, :string 
    end 
end 

但是模式文件仍然难道不更新

Answer 1

刚刚重建DB在发展使用：rake db:drop db:create db:migrate。这个命令应该丢弃数据库并从头开始重建它，包括schema.rb。

如果这不起作用，请更改新的迁移。可能你有错误（例如方法名称中的错字等）。
