Schedulable

"Schedulability" to your models, as simple as 1, 2,

schedulable

Just install.

$ script/plugin install git://github.com/cementhorses/schedulable.git

Options

Calling schedulable automatically hooks a few methods to a published_at column:

• scheduled? (true if the item is scheduled to be published but isn't yet)
• published? (true if the item is published)

The real power is when expiration is a question

schedulable :end => :archived_at

or

schedulable :published_at, :archived_at

does a little more:

• scheduled? :archived_at (true if archived_at is set in the future)
• archived? (true if the item has been archived)

with a note:

• published? returns false when archived? returns true.

It's all semantic sugar:

schedulable :activated_at, :terminated_at, :end_required => true

therefore creates:

• activated?
• terminated?

And that last option? It just adds a validation requiring the :end to be set if the :start is.

We have your other validations taken care of, too. We're just more comfortable with things when they're chronological.

Rails 2.1 Is Extra Sweet

named_scope support means a few extra methods.

class NewsItem < ActiveRecord::Base
  schedulable :published_at, :archived_at
end

Now you can scope it out:

• NewsItem.scheduled returns news items scheduled to be published
• NewsItem.published returns published news items
• NewsItem.archived returns archived news items
