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，我有一个系统的＆＃34;文档超过允许的最大BSON大小。最大值是16777216。＆＃34;。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Ruby驱动程序示例（http://docs.mongodb.org/ecosystem/tutorial/ruby-driver-tutorial/#gridfs）。

我使用的是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)

我的日志：

仅供参考，line server.rb：530对应

@grid.insert_one(grid_file)

注意：

完全相同的代码与＆lt; 16 MB文件，即插入机会和文件文件
当我使用mongofiles命令时，一切正常......
数据库中的其他插入可以从我的应用程序中正常工作

感谢您的帮助

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
