ruby - 使用 GridFS 时出现 "Document exceeds allowed max BSON size. The max is 16777216."错误

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，并且我有一个系统的“文档超出允许的最大 BSON 大小。最大值为 16777216。”。我认为在 mongo 集合中插入大于 16 MB 的文件的唯一方法是使用 Gridfs，所以我怀疑我做错了，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:

仅供引用，server.rb:530 行对应于

@grid.insert_one(grid_file)

注释:

• 对于 < 16 MB 的文件，同样的代码也能正常工作，即插入机会文档和文件文档
• 当我使用 mongofiles 命令时一切正常...
• 数据库中的其他插入在我的应用程序中工作正常

谢谢你的帮助

根据 mongodb jira ticket RUBY-946 ，这是一个错误，应该在新发布的 Ruby 驱动程序 2.0.5 中得到纠正。请参阅 this google group 中的评论
