merb_watchable
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).
config
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] = 'your.email@here.com'
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
end
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).
