In case you're creating a script to run under rails runner you can use the following approach:

File.open("#{Rails.root}/spec/fixtures/documents.yml", 'w') do |file|
  file.write Document.all.to_a.map(&:attributes).to_yaml
end

you can create as much blocks as you want, or if you want to go to the full database you can try:

models = defined?(AppicationRecord) ? ApplicationRecord.decendants : ActiveRecord::Base.descendants
models.each do |model|
  model_name = model.name.pluralize.underscore
  File.open("#{Rails.root}/spec/fixtures/#{model_name}.yml", 'w') do |file|
    file.write model.all.to_a.map(&:attributes).to_yaml
  end
end

if you do not want the timestamps you can change the code to: model.all.to_a.map { |m| m.attributes.except('created_at', 'updated_at')}.to_yaml
