Subject: CGI - Ruby Data Types

Hi all, me again, jeez im clocking up some traffic, sorry

thanks for all your help before, it was just me been stupid and leaving out
an enclosing quote for the hash key lookup doh !

Im from a perl background so im having some trouble as I am not used to
having to check my data types

for example , I have my CGI script

cgi = CGI.new
id = cgi['id']

prj = Project.new(id)
print prj.DisplayProject

when I print id.type is states that it is an array ?

my project class needs to check the value of id because if it is passed as a
valid ie > 0 integer then the user is requesting you to load the data for
the project, the problem is it never fails below so when no id is passed
then it still tries to execute the SQL

def initialize(id)

		if id
			
			db = Db.connection
			sql = SQL_PROJECT + " WHERE prj_id = #{id} "
			print sql
			qry = db.prepare(sql)
			qry.execute
			@data = qry.fetch_hash
			qry.finish
		end
		
end


In a month or two I will probably be thinking how simple this all is but we
all have to learn the intricasies, other than that ruby kicks butt as a
language, no more worrying about unreadable perl code, or pythons quirks
with properties in classes and finally Visual Basic, well they say its a
language :-)

Thanks again
