I have a script which I need to create a new Time or Date object to
compare 2 dates for deletion. ie to delete files older than a stipulated
date
But i tend to get this error, undefined method 'parse' for
DateTime:class or undefined method 'strptime'
Can anyone tell me what is wrong? A snippet of my code is as follows:
···
folders.each do |folder|
Dir.glob(folder+"/*") do |file|
match = regexp.match(File.basename(file))
match1 = regexp1.match(File.basename(file))
matchExp = excep_yyyymmdd.match(File.basename(file))
matchExp1 = excep_ddmmyyyy.match(File.basename(file))
if match
file_date = DateTime.strptime(match[1])
if matchExp != nil or matchExp1 != nil
if $keepLastMthDay == true or $keepLastMth == true
puts "File Escaped: #{file} (Keep last day of month option >activated)"
elsif $keepLastMthDay == false and $keepLastMth == false
if delete_date > file_date
size = (File.size(file))/1024
deleted_files << fileData.new(file,size)
puts "Files/Folders deleted: #{file} size: #{size} KB" #FileUtils.rm_r file
end #if
end #if
elsif matchExp == nil or matchExp1 == nil
if delete_date > file_date
size = (File.size(file))/1024
deleted_files << fileData.new(file,size)
puts "Files/Folders deleted: #{file} size: #{size} KB" #FileUtils.rm_r file
end #if
end # if matchExp

strptime() is essentially undocumented, so I can't help you there. But
here are some other ways to do what you want:
Hi, thanks for that, did'nt know you can do it this way
However, I have 2 formats, one yyyymmdd and the other just ddmmyyyy(w/o
any dashes). Unfortunately Parsedate cannot be used for ddmmyyyy. Only
yyyymmdd can work. Any ideas?

or is there any way that we can convert something like ddmmyyyy to
yyyymmdd so that it'll work when we use Date or parsedate to parse dates
in order to not raise an invalid date error?

Any string can be parsed using one of the examples I posted.

Date.strptime('20081020',"%Y%m%d")
undefined method `strptime' for Date:Class (NoMethodError)
Date.parse('20081020',"%Y%m%d").to_s
undefined method `parse' for DateTime:Class (NoMethodError)
and im running ruby 1.8.5.. could it be why this has a prob? Like a bug
or something?
It appears that Date.parse() and Date.strptime() are/were broken, and
therefore the defacto means for parsing Dates from Strings are the
Standard Library modules: ParseDate and Scanf. For instance, "The
Ruby Way" doesn't even mention Date.parse() or Date.strptime() when
discussing how to get Dates from Strings. And pickaxe2 doesn't cover
the Date/Time subject at all.
