# what is the idiomatic ruby for this:
# if the var is an array, do_something with each element, otherwise just do something with the var
# if var.is_a?(Array)
#   var.each do |element|
#     do_something(element)
#   end
# else
#   do_something(var)

# I don't tend to like writing this kind of code:

if Rails.env == 'development' or Rails.env == 'staging'
  # ...
end

# So, an alternative Ruby way to do this is:

if %w(development staging).include?(Rails.env)
  # ...
