Get a hash/array with a range of dates?

Rails
1

I’m trying to build options for a select box that would output a range
of dates between two dates that I specified. For example, if my two
dates (both coming from datetime fields in a MySQL database) were:

October 25th, 2006
October 29th, 2006

I’d like to output options like this:

(option value=“2006-10-25”)October 25th, 2006(/option)
(option value=“2006-10-26”)October 26th, 2006(/option)
(option value=“2006-10-27”)October 27th, 2006(/option)
(option value=“2006-10-28”)October 28th, 2006(/option)
(option value=“2006-10-29”)October 29th, 2006(/option)

I can’t figure out how to get the range of dates into a collection. I
tried doing:
@range_of_dates = @first_date…@second_date

But it didn’t work. Does anyone know how I can do this?

Thanks,

Ruby DATE class implements the “upto” method, so assuming you can
massage @first_date and @second_date as DATE objects, you should be able
to do something like this (in your view):

<% @first_date.upto(@second_date) do |date| %>
(option value="<% date.to_s %>")<% date.to_s %>(/option)
<% end %>

Of course, you’ll need to massage the output of date.to_s to get the
formats that you want - strftime method does this for Time objects, not
sure if it applies for Date objects.

Another option…

In your controller:

@range_of_dates = @first_date.upto(@second_date).map {|date| [date.to_s,
date.to_s]}

In your view:

<%= select(‘object’,‘method’,@range_of_dates) %>

Again, you’ll want to get the formats of the date.to_s correct in the
first line of code. The first date.to_s is what is used for the display,
the second is what is used for the value.
