There are a couple things you can do. First, if you're using webrat
and you've labeled fields exactly as you have them in that feature,
you can offload the work to webrat:
When /^I fill in "(.*)" with "(.*)$/" do |field, value|
fills_in field, :with => value
end
Or you can do some kind of transformation:
prop_map = {"User name" => :username}
When /^I fill in "(.*)" with "(.*)$/" do |prop_name, value|
fills_in prop_map[prop_name], :with => value
end
or if you're accessing the model directly
@user.send(prop_map[prop_name] + '=', value)
Looking back at the full email now though I think you're asking about
how to just convert MyUser to myuser?
class User < ActiveRecord::Base
def username=(new_username)
self[:username] = new_username.downcase
end
end
or non-AR
class User
attr_reader :username
def username=(new_username)
@username = new_username.downcase
end
end
Is that what you're looking for?
