Question

我有一个mongodb连接的sinatra，我收到了这个错误

“ERROR TypeError：无法将BSON :: Document转换为字符串”

当我尝试使用insert_one命令时。要尝试post操作，我使用curl和这个命令：

curl -i -F project_id = Test_project -F filedata=@jmeter.log http://myserver/v1/upload/media

我的代码是：

post "/v1/upload/media" do
        #Return 400  If project_id does not exist
        return status 400 if params['project_id'].empty?

        files_h = Hash.new
        files_collect = settings.mongo_db[:media]

        File.open('uploads/' + params['filedata'][:filename], "w") do |f|
            puts "File size #{params['filedata'][:tempfile].size}"
            f.write(params['filedata'][:tempfile].read)
            files_h['name'] = params['filedata'][:filename]
            files_h['sha1'] =  Digest::SHA1.file(f).hexdigest
        end
        files_h['project_id'] = params['project_id']
        puts files_h
        puts params
        #Check if the file exist
        if files_collect.find(:name => files_h['name']).count == 0
                #Inserting the data into DB
                 settings.mongo_db[:media].insert_one(files_h)
        else

        end
    end

服务器日志也是：

关于什么是问题的任何想法？，我有其他insert_one代码使用哈希没有问题。

提前致谢。

最后添加“返回状态200”解决了类型错误，似乎sinatra发生了一些事情，即尝试将生成的BSON :: Document转换为字符串。
