MerbWatchable sends you emails when your stuff is modified. It's built for merb 1.0.3+, and currently assuming DataMapper.

merb_watchable is a pretty simple slice for alerting users when model objects they're "watching" are saved. Right now, it assumes that you have a User class called User (sorry about that, hope to fix soon for those of you Person class authors) with a field called email (once again, apologies).


Unfortunately not much config at the moment, this is pretty bare. You can specify the "from:" in the email with the following:

Merb::Slices::config[:merb_watchable][:sender] = ''

Add that to your Merb::BootLoader.before_app_loads and you should be in good shape. Obviously, make sure you've required merb-mailers and that your Merb Mailer config is in good working order.

Here's an example of a model:

class WatchedModel
  include DataMapper::Resource
  property :id, Serial
  property :title, String
  is :watchable, :label => :title

Note the is :watchable part there. Stick that in your model, and your model will be, well, watchable. The :label option allows you to specify how the model will be referred to. If you don't specify anything, watchable will assume that you have a field in your model called "name", and will show that field in the email.

using merb_watchable

The slice will automatically add a watches table to keep track of what objects are currently being watched. To those of you writing merb apps dedicated to wrist watches, again, I apologize. Here's what you need to do in order to specify that the current user is watching an object:

Watch.create(:watcher => session.current_user, :watchable => your_object)

Voila, you're done. (Or as I once overheard, "Viola! You're done!") Check the TODO page for what needs to be done (which is a lot, at the moment).
