Hi,
This is kind of weird thing, I cannot explain it, but I will show you my
code - this would explain it better.
I have a helper method:
def month_in_words(month)
logger.debug(month)
Time.parse(month).strftime("%b")
end
and in my view I have:
<% @array.each do | ar | %>
<%= month_in_words(ar) %>
<% end %>
The result I''m getting in the view is the same for every call to helper
method month_in_words even if it''s getting different value in the
parameter?
View:> Jun
> Jun
> Jun
> Jun
Debugger (from ruby script/server console):> 06
> 05
> 04
> 03
Why do I keep getting Jun, is this a error within RubyonRails or is it
something I did not understand yet?
Please explain :)

Jamal,
Your code does explain what''s going on. Time.parse is not returning
what you would expect because you are passing in just the String
representation of a month (rather than of a complete date). An easy
way to make it do what you want is to tack on a day to the end of the
string.
For instance (in IRB):
>> Time.parse("03")
=> Sat Jun 02 12:46:40 CDT 2007
>> Time.parse("04")
=> Sat Jun 02 12:46:44 CDT 2007
>> Time.parse("03/01")
=> Thu Mar 01 00:00:00 CST 2007
>> Time.parse("04/01")
=> Sun Apr 01 00:00:00 CDT 2007
>> Time.parse("04/01").strftime("%b")
=> "Apr"
I hope this helps,
David

Why is that? Since I''m passing it different month number as a string, shouldn''t it look at them as separate numbers as strings? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Is it a month? A year? A day? There''s no real way to tell. The way Time.parse works is it tries to match the string you pass in against a series of patterns. Most of the time, it does what you want. (i.e., if a person could tell how to interpret the string as a date, Time.parse probably will be able to as well). The exact details of how it does the matching, however, are complex. The best place to look is probably the source code -- see the _parse method in date/format.rb in the standard libs if you want to see exactly what it''s doing -- there''s a lot of code there, but it''s pretty readable, as long as you grok regular expressions.
