How can I iterate through all of the Models in my rails app?

Question

I would like to be able to iterate over and inspect all the models in my rails app. In pseudo-code it would look something like:

rails_env.models.each do |model|

I tried implementing the above solutions under Rails 5 and they didn't quite work. Here's a solution which finds all models which starts with "page_" (or any other prefix; just specify that):

def self.page_models(prefix = "page")
    models = []
    folder = File.join(Rails.root, "app", "models")
    Dir[File.join(folder, "*")].each do |filename|
     if filename =~ /models\/#{prefix}/
       klass = File.basename(filename, '.rb').camelize.constantize
       models << klass
     end
    end
    return models
end
