Question

使用activeresource获取图书集。

我有一个从活动资源扩展的类，如下所示：

class BookResource < ActiveResource::Base
  self.site = "http://api.book.com:3000/"
end

这是我的books_controller.rb

class BookController < ApplicationController
  def index
    @book = Book.find(:all)
  end
end

在rails控制台中运行以下命令：

2.1.2 :009 >   BookResource::Book.find(:all)

实际上使用上述调用时，会出现一个名为

的错误

“ArgumentError：期望属性Hash，得到[”total_entries“， 38]“

2.1.2 :009 >   BookResource::Book.find(:all)
