MongoID，Rails 3.1的數據表問題

Question

我正在使用一個支持MongoID的datatables gem（ https://github.com/potatosalad/mongoid-data_table ），但是以下代碼引發了異常

format.json do
    render :json => Game.to_data_table(self)
end

Game.to_data_table(self)


INTERNAL ERROR!!! undefined method `page' for #<Array:0xb38d7bc>

這些是我的蒙哥寶石

gem 'mongo'
gem "mongoid", "~> 2.1"
gem 'bson', '= 1.4.0'
gem 'bson_ext', '= 1.4.0'

Answer 1

我知道有一次bson 1.4.0 gem出現了問題，他們實際上撤消了它，然后又重新推出了一個。 也許嘗試升級bson和bson_ext gem。 您可以從Gemfile中刪除mongo gem，因為它是mongoid的依賴mongoid 。 同樣，您可以從Gemfile中刪除bson gem，因為它是mongo的依賴項（這是mongoid的依賴mongoid ）。 還要刪除bson_ext gem的版本規范。 然后執行bundle update bson和bundle update bson_ext 。 看看是否能解決問題。
