Question

I have lets say 5 models.

Thread
Poll
Message
Wall
Zone

I would like something where I can loop through each model contained in the string or array, and if that model has a user_id field, update it to whatever I’d like to set it to.

Any Idea on how you can do something like

[Thread.where(:user_id => XXX)].each do |model|
 ...
end

Where Thread is looped through in a list of models [“Thread”, “Poll”, ….]

Thanks

try this:

models = ["Thread", "Poll", ....]

models.each do |model|
  model = model.constantize
  if model.columns.map(&:name).include?("user_id")
    model.where(:user_id => my_user_id).each do |m|
      do_stuff_with(m)
    end
  end
end
