Makes it easy to make forms for recurring events. NOTE: ABANDONED

Schedule Attributes

Schedule Attributes allows models (ORM agnostic) to accept recurring schedule form parameters and translate them into an IceCube Schedule object. Schedule Attributes adds #schedule_attributes and #schedule_attributes= methods that let your model automatically populate Rails forms and receive HTML form parameters. Additionally, it provides access to the IceCube::Schedule object itself.

Usage

To use, include the ScheduleAttributes module in your model class.

class SomeModel
  include ScheduleAttributes
end

Your model must respond to :schedule_yaml and :schedule_yaml=, because ScheduleAttributes will serialize and deserialize the schedule in YAML using this column. If you are using ActiveRecord, make a string column called schedule_yaml. If you're using Mongoid, make a string field like so: field :schedule_yaml.

You model will gain the following methods:

schedule_attributes=

Accepts form a parameter hash that represent a schedule, and creates an IceCube::Schedule object, and serializes it into your schedule_yaml field.

E.x.

@event.schedule_attributes = params[:event][:schedule_attributes]

Parameters Accepted

Because they are coming from a form, all parameters are expected to be in string format.

:repeat

Can be 0 or 1. The parameter should respond to :to_i. 0 indicates that the event does not repeat. Anything else indicates that the event repeats.

Parameters for non-repeating events

The following parameters will only be used if the repeat parameter is 0.

:date

The date that this (non-repeating) event is scheduled for. Should be parseable by Time.parse. This parameter is only used if :repeat is 0.

Parameters for repeating events

The following parameters will only be used if the repeat parameter is 1.

:start_date

The date at which the event starts repeating. Must be parseable by Time.parse.

:interval_unit

The interval unit by which the event repeats. Can be "day" or "week". For example, if the even repeats every day, this would be "day". If it repeats weekly, this would be "week".

:interval

The interval by which the event repeats. Should be an integer (in string format). For example, if the event repeats every other day, this parameter should be 2, and :interval_unit should be "day". If it repeats every other week, it should be 2 and interval unit should be "week".

:sunday, :monday, :tuesday, :wednesday, :thursday, :friday, :saturday

Indicates with a 0 or 1 whether the event repeats on this day. For example, if the event repeats every other week on Tues and Thursday, then the parameters would include these: :interval => "2", :interval_unit => "week", :tuesday => "1", :thursday => "1". These parameters are only used if :repeat is 1 and :interval_unit is "week".

schedule_attributes

Provides an OStruct with methods that correspond to the attributes accepted by #schedule_attributes=. ActiveRecord can use this object to populate a form using FormHelper#fields_for.

##schedule

Returns a the IceCube::Schedule object that is serialized to the model's schedule_yaml field. If there is none, it returns a schedule with start_date of the current date, recurring daily, ending never.
