CalendarHelper
|
||||
==============
|
||||
|
||||
A simple helper for creating an HTML calendar. The "calendar" method will be automatically available to your view templates.
|
||||
|
||||
There is also a Rails generator that copies some stylesheets for use alone or alongside existing stylesheets.

||||

# CalendarHelper allows you to draw a databound calendar with fine-grained CSS formatting
|

module CalendarHelper
|
||||
# Returns an HTML calendar. In its simplest form, this method generates a plain
|
||||
# calendar (which can then be customized using CSS) for a given month and year.
|
||||
# However, this may be customized in a variety of ways -- changing the default CSS
|
||||
# classes, generating the individual day entries yourself, and so on.
|
||||
#
|
||||
# The following options are required:
|
||||
# :year # The year number to show the calendar for.
|
||||
# :month # The month number to show the calendar for.
|
||||
#
|
||||
# The following are optional, available for customizing the default behaviour:
|
||||
# :table_class => "calendar" # The class for the <table> tag.
|
||||
# :month_name_class => "monthName" # The class for the name of the month, at the top of the table.
|
||||
# :other_month_class => "otherMonth" # Not implemented yet.
|
||||
# :day_name_class => "dayName" # The class is for the names of the weekdays, at the top.
|
||||
# :day_class => "day" # The class for the individual day number cells.
|
||||
# This may or may not be used if you specify a block (see below).
|
||||
# :abbrev => (0..2) # This option specifies how the day names should be abbreviated.
|
||||
# Use (0..2) for the first three letters, (0..0) for the first, and
|
||||
# (0..-1) for the entire name.
|
||||
# :first_day_of_week => 0 # Renders calendar starting on Sunday. Use 1 for Monday, and so on.
|
||||
#
|
||||
# For more customization, you can pass a code block to this method, that will get one argument, a Date object,
|
||||
# and return a values for the individual table cells. The block can return an array, [cell_text, cell_attrs],
|
||||
# cell_text being the text that is displayed and cell_attrs a hash containing the attributes for the <td> tag
|
||||
# (this can be used to change the <td>'s class for customization with CSS).
|
||||
# This block can also return the cell_text only, in which case the <td>'s class defaults to the value given in
|
||||
# +:day_class+. If the block returns nil, the default options are used.
|
||||
#
|
||||
# Example usage:
|
||||
# calendar(:year => 2005, :month => 6) # This generates the simplest possible calendar.
|
||||
# calendar({:year => 2005, :month => 6, :table_class => "calendar_helper"}) # This generates a calendar, as
|
||||
# # before, but the <table>'s class
|
||||
# # is set to "calendar_helper".
|
||||
# calendar(:year => 2005, :month => 6, :abbrev => (0..-1)) # This generates a simple calendar but shows the
|
||||
# # entire day name ("Sunday", "Monday", etc.) instead
|
||||
# # of only the first three letters.
|
||||
# calendar(:year => 2005, :month => 5) do |d| # This generates a simple calendar, but gives special days
|
||||
# if listOfSpecialDays.include?(d) # (days that are in the array listOfSpecialDays) one CSS class,
|
||||
# [d.mday, {:class => "specialDay"}] # "specialDay", and gives the rest of the days another CSS class,
|
||||
# else # "normalDay". You can also use this highlight today differently
|
||||
# [d.mday, {:class => "normalDay"}] # from the rest of the days, etc.
|
||||
# end
|
||||
# end
|
||||
#
|
||||
# An additional 'weekend' class is applied to weekend days.
|

#
|

# For consistency with the themes provided in the calendar_styles generator, use "specialDay" as the CSS class for marked days.
