Helper to generate css-id from AR model. Do I have alzheimers?

On one of the many Rails projects I’ve worked on over the years, I
seem to recall using either a helper or a method on a model to
generate a css id based on the model class and id. It was very useful
particularly in making views more testable in RSpec/Cucumber.

I can’t remember if this was part of rails, or from a plugin or
something specific to the project.

I’ve failed to find anything like this in the rails docs.

Any ideas what this might have been?

Are you thinking of dom_id / dom_class ?

If you’re using Haml, it’s even easier: just use the [@object] syntax.

Interesting… was not aware of this. Just today was writing a helper
method
to create a friendly id for an object I am writing to a table row. The
challenge with dom_id/class is that when using Cucumber you really do
not
know (without making a good guess) what the id of a record will be.

I am curious if anyone has done or thought of the following for models,
something where one defines what fields would constitute a friendly
field id
which does not involve the index but fields that would be known in a
Cucumber scenario? I seem to be writing helpers for this quite often as
it
seems like often the best strategy for checking for something on a page
is
to place the data with an id or as a child of some object with a
specific id
or class. I am not quite sure how to do this as it seems it would have
to
extend ActiveModel/ActiveRecord…or maybe be done in a module which can
be
aware of what constituted the friendly_id of a model:

include FriendlyId
class Borrower < ActiveRecord::Base
friendly_id :last_name, :first_name # so in each model you just define
what fields of the model will constitute the friendly id
end

module FriendlyId
def friendly_id
# how do I access the ‘friendly_id’ settings from the model I am
mixed
in to?
end
end

borrower = Borrower.new(:last_name => “Kahn”, :first_name => "David) #
using
ActiveRecord/ActiveModel

borrower.friendly_id

“kahn_david”

or

friendly_id(borrower)

David
