Rails 4模型子文件夹 [英] Rails 4 model subfolder

问题描述

我在app/models/request/book文件夹中创建了模型，但是Book :: Request :: Status.table_name返回表名"statuses"("book_request_statuses"-是正确的表名).如何获得正确的表名?

I'm created model in app/models/request/book folder but Book::Request::Status.table_name returns table name "statuses" ("book_request_statuses" - is right table name). How I can get correct table name?

模型位置

model/
  book/
    request/
      status.rb

模型/书/请求/状态.rb

class Book::Request::Status < ActiveRecord::Base
...
end

config/application.rb

config.autoload_paths += Dir[Rails.root.join('app', 'models', '**', '*.rb')]

如果我设置self.table_name ="book_request_statuses"，则该模型可以正常工作(在模型中)，但这不是好方法:).

If I set self.table_name = "book_request_statuses" then the model will work correctly (in model), but it's not good way :).

对不起，我的英语不好

推荐答案

1)使用以下几行在app/models/book.rb中创建一个模块.

1) Create a module in app/models/book.rb with these lines.

module Book
  def self.table_name_prefix
    'book_'
  end
end

2)然后在app/models/book/request.rb

2) Then create another module in app/models/book/request.rb

module Request
  def self.table_name_prefix
    'request_'
  end
end

3)将状态模型放入app/models/book/request/目录中.

3) Put the status model inside the app/models/book/request/ directory.

4)保留其他所有文件.

4) Keep all the other files intact.
