    • Type: Bug
    • Status: Closed
    • Priority: Major - P3
    • Resolution: Gone away
    • Affects Version/s: 2.1.0
    • Fix Version/s: 12_01_17
    • Component/s: None
    • Labels:
      None
    • Environment:
      ruby (2.1.7)
      mongo (2.1.0)
      mongoid (5.0.0)

      Description

      Please read the following and notice that bulk update `find` doesn't even
      match a document when `upsert => false`. Also notice with `upsert=>true` it does match a document but doesn't update the `products`. Doesn't make any sense. Is there a workaround?

      2.1.7 :001 > class Something

      2.1.7 :002?> include Mongoid::Document

      2.1.7 :003?> field :products, :type => Array

      2.1.7 :004?> end

      => #<Mongoid::Fields::Standard:0x007f83b4e075b0 @name="products", @options={:type=>Array, :klass=>Something}, @label=nil, @default_val=nil>

      2.1.7 :006 > Something.delete_all

      => 0

      2.1.7 :007 > Something.create :products => [1,2,3,4]

      => #<Something _id: 56ddec0464b1f31186000000, products: [1, 2, 3, 4]>

      2.1.7 :008 > Something.first

      => #<Something _id: 56ddec0464b1f31186000000, products: [1, 2, 3, 4]>

      2.1.7 :009 > Something.mongo_client[:something].bulk_write([{ :update_one => { :filter =>

      { "_id" => BSON::ObjectId("56ddec0464b1f31186000000")}

      , :update => {"$set" => {"products"=>[6,7]}}, :upsert => false } }])

      => #<Mongo::BulkWrite::Result:0x007f83b1e4eb48 @results=

      {"n_modified"=>0, "n_upserted"=>0, "n_matched"=>0, "n"=>0, "upserted_ids"=>[]}
