“文档超出了允许的最大BSON大小。最大值为16777216。”使用GridFS时出错

Question

我正在尝试使用GridFS和ruby在我的mongo数据库中插入一个33 MB的视频文件，我有一个系统性的“文档超过了允许的最大BSON大小。最大为16777216。”。我认为在mongo集合中插入大于16MB的文件的唯一方法是使用Gridfs，所以我怀疑我做得不对，即使我复制/粘贴了Ruby驱动程序示例(http://docs.mongodb.org/ecosystem/tutorial/ruby-driver-tutorial/#gridfs).

我正在使用Ruby 2.2。1，mongo驱动程序2.0。4和mongo db 3.0。1.我的代码：

eDatabase = Mongo::Client.new(......)
@grid = @eDatabase.database.fs


myvideo = File.open("files/33mo.mov", 'rb')

grid_file = Mongo::Grid::File.new(myvideo.read, :filename => "myvideo.mov")
@grid.insert_one(grid_file)

还有我的日志：

仅供参考，server.rb:530行对应于

@grid.insert_one(grid_file)

笔记：

多谢你的帮忙

根据mongodb jira ticket RUBY-946，这是一个bug，应该在新发布的RUBY驱动程序2.0中进行更正。5.请参阅此谷歌群中的评论
