我是可怕的,在命名和认识到,有一个更好的设置我的Rails应用程序为我的模型的名称。有没有一种方法使用移民来重命名一个模型,其表?
I'm terrible at naming and realize that there are a better set of names for my models in my Rails app. Is there a way to use a migration to rename a model and its table?
下面是一个例子:
class RenameOldTableToNewTable< ActiveRecord::Migration
def self.up
rename_table :old_table_name, :new_table_name
end
def self.down
rename_table :new_table_name, :old_table_name
end
end
我不得不去手动重命名模型声明文件。
I had to go and rename the model declaration file manually.
编辑:
在Rails 3.1和放大器; 4,ActiveRecord的::移民:: CommandRecorder知道如何扭转rename_table迁移,所以你可以这样做:
In Rails 3.1 & 4, ActiveRecord::Migration::CommandRecorder knows how to reverse rename_table migrations, so you can do this:
class RenameOldTableToNewTable< ActiveRecord::Migration
def change
rename_table :old_table_name, :new_table_name
end
end
(你还是要通过手动重命名文件。)
(You still have to go through and manually rename your files.)
