Rails 4 MongoID Upsert尝试

我一直试图找一个合适的命令做一个upsert，但我失败了。Rails 4 MongoID Upsert尝试

这里是我尝试：

csv.each do |row| 
     inner = {} 
     if row['PN'] != 'TOTAL' 
      time = Time.now 
      stamp = time.strftime("%F") 
      inner = { 
    'PN' => row['PN'], 
    'thisWkUse' => row['this WK Usage'], 'thisWkFail' => row['this WK Failure'],  'thisWkFailPercent' => row['this WK Failure%'].gsub('%',''), 
    'prev4WkUse' => row['Previous 4 WK Usage'], 'prev4WkFail' => row['Previous 4 WK  Failure'], 'prev4WkFailPercent' => row['Previous 4 WK Failure%'].gsub('%',''), 
    'Platform' => row['Platform'].gsub('%',''), 
    'created' => stamp 
        } 
      @report = Report.find(PN: inner['PN'], Platform: inner['Platform']).update(inner,[upsert: true ]) 
      @report.upsert() 
     end 
    end

这是我看到的错误：

MOPED: someip:someport QUERY  database=reidb collection=reports selector={"_id"=> {:PN=>"7056733", :Platform=>"CALLISTO_PLUS"}} flags=[] limit=0 skip=0 batch_size=nil fields=nil  runtime: 92.2640ms 
Completed 500 Internal Server Error in 447ms 

NoMethodError (undefined method `upsert' for nil:NilClass): 
app/controllers/reports_controller.rb:54:in `block in upload' 
app/controllers/reports_controller.rb:42:in `upload'

这里是模型：的

class Report 
    include Mongoid::Document 
    field :_id, type: Object 
    field :PN, type: String 
    field :thisWkUse, type: Integer 
    field :thisWkFail, type: Integer 
    field :thisWkFailPercent, type: Float 
    field :prev4WkUse, type: Integer 
    field :prev4WkFail, type: Integer 
    field :prev4WkFailPercent, type: Float 
    field :Platform, type: String 
    field :created, type: Date 
    index({ _id: 1,PN: 1, Platform: 1 }, { unique: true, background: true , drop_dups: true}) 
end

您想要为查询使用'where'方法（而不是'find'），请参阅http://mongoid.org/en/mongoid/docs/querying.html – 2014-09-06 13:23:09

尝试过的报告= Report.where（：PN => inner ['PN']，：Platform => inner ['Platform']）.new（inner）和reports.upsert，并在第二次导入时获得重复记录。 – 2014-09-06 23:02:02

请尝试：@report = Report.where（PN：inner ['PN']，Platform：inner ['Platform']）。upsert（inner） – 2014-09-08 17:19:31

无上面一个衬垫为我工作，所以我做了丑陋的方式：

inner = { 
'PN' => row['PN'], 
'thisWkUse' => row['this WK Usage'], 'thisWkFail' => row['this WK Failure'],  'thisWkFailPercent' => row['this WK Failure%'].gsub('%',''), 
'prev4WkUse' => row['Previous 4 WK Usage'], 'prev4WkFail' => row['Previous 4 WK Failure'], 'prev4WkFailPercent' => row['Previous 4 WK Failure%'].gsub('%',''), 
'Platform' => row['Platform'].gsub('%','') 
     } 
@test = Report.where(:PN => inner['PN'], :Platform => inner['Platform']).count 
if @test == 0 
    @reports = Report.new(inner) 
    @reports.save 
elsif @test == 1 
    @reports = Report.where(:PN => inner['PN'], :Platform =>  inner['Platform']).update(inner) 
else 
    limit = @test - 1 
    @nuke = Report.where(:PN => inner['PN'], :Platform =>  inner['Platform']).limit(limit).delete 
    @reports = Report.where(:PN => inner['PN'], :Platform =>  inner['Platform']).update(inner) 
end
