用哈希更新Rails中的MongoDB文档

Question

Curiosity led me to ask this question. Is any of you tried to update document/record with an hash of keys & values? I am using rake task here.

For example I have:

data = {"year" => "2015", "category" => "Action" }
movie = Movie.where(title: "Avangers").first
## some code ##
movie.save

Is there any easy way to update record with new keys and values in one line?

Answer 1

begin
  movie = Movie.where(title: "Avangers").first
  raise Mongoid::Errors::DocumentNotFound unless movie
  movie.update!(year: "2015", category: "Action")
rescue Mongoid::Errors::MongoidError => e
   logger.error(e.message)
end
