Hi,
I am struggling with the problem:
I want to extend Ruby''s Time class to add 3 new methods
(Mayan Calendar calculations).
I can do it by placing time.rb in lib/ directory
class Time
def first_method
..
end
end
However, I noticed that doing so I lost access
to some of Ruby''s Time extensions (eg. parse and httpdate
methods)
Looks like Rails parses my time.rb but rejects to parse Ruby''s time.rb
extension library.
I also tried
require ''time''
class Time
..
end
and
class Time
class << Time
..
end
end
but no results.
I am wondering what the solution is.

Now when the time.rb-File ist required, Ruby first finds your File (instead of Ruby''s own version) and includes this. So you are not extending but replacing time.rb! I had the same problem when extending date.rb. Simple solution: call the file something different (for example ''time_modified.rb'' and include a require ''time_modified''-Line in your environment.rb. This worked fine for me. Michael
don''t call your extensions ''time.rb'' call instead something like ''time_ext.rb'' On 6/30/05, Karol Hosiawa <hosiawak-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi, > I am struggling with the problem: > I want to extend Ruby''s Time class to add 3 new methods > (Mayan Calendar calculations). > > I can do it by placing time.rb in lib/ directory > class Time > def first_method > .. > end > end > However, I noticed that doing so I lost access > to some of Ruby''s Time extensions (eg. parse and httpdate > methods) > Looks like Rails parses my time.rb but rejects to parse Ruby''s time.rb > extension library. > I also tried > > require ''time'' > class Time > .. > end > > and > > class Time > class << Time > .. > end > end > > but no results. > I am wondering what the solution is. > > Karol > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails >
