Mail filters like functionality in Ruby on Rails

Rails
1

For my new project, I need a functionality like mail filters. There will
be a set of rules with associated actions. When an user submits a
request, it needs to be passed through these rules for filtering. In
case any one of these rules matches, the corresponding action should be
triggered (the model will be updated with a few more attributes or an
email will be to a few people etc.,). Just like mail filters.

And, these rules will be user specific and stored as ActiveRecord
models.

Any pointers for existing gems?!

My ROR version is 2.3.8

P.S :- This will be more of business rules. For ex.,
In a CRM application, if the request is from a particular company or for
a particular product or based on timezone etc., assign to this group,
set it to high priority etc.,

Do you need any? This should be pretty easy to build: just make a bunch
of Filter objects and process them in some specified order.

If you need to track request state, acts_as_state_machine might help.

My ROR version is 2.3.8

If this is a new project, as you say above, please start with the
current version of Rails, which is now 3.0.1.

a particular product or based on timezone etc., assign to this group,
set it to high priority etc.,

I could have sworn I’d seen a Ruby version of Drools, but can’t find it
now; in any case google ruby rules engine and you’ll get some things
to check out :slight_smile:

Hi Marnen,

  1. These requests will be both e-mail and as well as requests through
    web interface.

  2. These filter objects are user/account based, so they need to be
    persisted in database. Also, should be editable from UI.

  3. I might not need state traversals. Act_as_state_machine is bit
    advanced at this point of time.

Thanks for the response.

Hi Hassan,

Earlier, I have tried searching both ‘Ruby version of Drool’ and ‘Ruby
Rules Engine’, didn’t get exactly what I was looking for.

Thanks,
Shan
