# 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)
  # ...
end

# But, it seems that the target is on the wrong side, reads funny, so, check this:

class Object
  def in?(*array)
    array.include?(self)
  end
end

# Then we can write:

if Rails.env.in?('development', 'staging')
  # ...
end

# Seems much nicer! What do you'se reckon?
