Question

@comments = []

@preComments = Comment.where(:resource_hash => resource_hash).
                       sort(:created_at.desc).all

@preComments.each do |comment|
  newComment = comment
  u = ::User.find_by_id comment.user_id

  newComment.display_name = "Some name"

  if u.image_location.nil?
    newComment.image_location = "defaultpic"
  else
    newComment.image_location = u.image_location
  end

    p u

    @comments << newComment

    p "HERE!!!!!"
  end

That’s my code, but I get an error saying

undefined method `display_name=' for #

So how do I assign a display_name?

Answer 1

Disclosure : I’ve never use MongoMapper

So my best bet is : just add display_name as part of the Comment schema. In models/comment.rb :

class Comment
  include MongoMapper::Document

  key :display_name,  String
  key ...
  [...]

end
