Rails - Jan 2012 - Chronic parsing date range in console but not in application in rails 3

Hey all,

Chronic will parse a date range in console:

Chronic.parse(1/1/2011 - 1/1/2012, :guess => false)
 => 2012-01-01 12:00:00 -0500..2012-01-01 12:00:01 -0500

However, when I use logger to check if it''s parsing in application, it
is not:

         logger.info "The value of history date is #{history_date}"
=>
The value of history date is 1/1/2011 - 1/1/2012
          logger.info "The value of date range is
#{ Chronic.parse(history_date, :guess => false)}" => The value of
date
range is

See how it returns nil for second logger. I have no clue why it works
fine in console but not in application.

thanks for response

This is strange what happened here. Chronic parse was not able to
parse a string when it contained a range like this:

"1/1/2011 - 1/1/2012"

So in order to address this, i had to check for the "-" in the string:

if history_date.include? "-"
              date_range              Chronic.parse(Date.parse(history_date),
:guess => false)

            else
              date_range              Chronic.parse(history_date, :guess =>
false)

            end


Im open to better solutions.

thanks for response

It seems to parse the date wrong:

Chronic.parse(eval("1/1/2011 - 1/1/2012"), :guess => false)
 => 2012-01-01 12:00:00 -0500..2012-01-01 12:00:01 -0500

I specify two years, 2011 and 2012. And it returns a range of 2012.

Actually it returns a span of 1 second :-)

I was assuming your original example worked, but it doesn''t. And I
haven''t worked with Chronic much, so I''m not sure if that
argument is
even something it''s expected to handle. For example this works fine:

ruby-1.9.2-p290 :007 > result = Chronic.parse(''last year'',
:guess => false)
 => 2011-01-01 00:00:00 -0800..2012-01-01 00:00:00 -0800
ruby-1.9.2-p290 :008 > result.class
 => Chronic::Span
ruby-1.9.2-p290 :009 > result.width
 => 31536000

while this obviously doesn''t:

ruby-1.9.2-p290 :010 > result = Chronic.parse(1/1/2011 - 1/1/2012,
:guess => false)
 => 2012-01-01 12:00:00 -0800..2012-01-01 12:00:01 -0800
ruby-1.9.2-p290 :011 > result.class
 => Chronic::Span
ruby-1.9.2-p290 :012 > result.width
 => 1
ruby-1.9.2-p290 :013 >

Time to jump into the gem source, I think  :-)
