Ruby Mongo Driver - Find_by_Id

Question

What am I doing wrong here? I know the _id is in the database but I get empty result.

@b = coll.find("_id" => "4db2ebee90036f010b000001")

Thanks

Answer 1

Use this:

coll.find(:_id => BSON::ObjectId('4db2ebee90036f010b000001')).each do |data| 
   puts data.inspect 
end

Answer 2

Using, Ruby version 2.3.1p112, mongo (gem) 2.4.2 and BSON (gem) 4.2.2

The following worked for me

client = Mongo::Client.new(['127.0.0.1:3001'], :database=>'dbname')
collection = client[:users]
user = collection.find({_id:'XY3h5R7aJkh5FxFhJ'}).first
