Instance Method Details

#events ⇒ Object

Returns an array of arrays containing hashes of events to fit in an HTML calendar week row.

Each hash in the array represents a table cell td when the calendar is generated. If the hash is empty, an empty td would be generated. Otherwise, the td will contain information related to the associated event. An event hash contains:

:event      =>  The event object.
:span       =>  The number of days this event takes up in the current week row.
:continued  =>  A boolean determining if this event starts before or ends after the current week.

For example:

puts @week.events.inspect

# [
#   [{}, {}, { :event => ..., :span => 1, :continued => false }, { :event => ..., :span => 1, :continued => false}, {}, {}, {}],
#   [{}, {}, { :event => ..., :span => 1, :continued => false }, {}, {}, {}, { :event => ..., :span => 1, :continued => true }],
#   [{}, {}, { :event => ..., :span => 1, :continued => false }, {}, {}, {}, {}],
#   [{}, {}, { :event => ..., :span => 1, :continued => false }, {}, {}, {}, {}],
#   [{}, {}, { :event => ..., :span => 4, :continued => false }, {}]
# ]
