Hi

I have @selected_ciid_and_asso_types ( its content is
3:43,2:65,3:50, )
How can i split it like

3 43
2 65
3 50

These are actually two columns of a table..If i get it like above I can
directly save it to database

I'm not sure if i really understand your question but if 3:43,2:65,3:50 is
actually a string i.e. "3:43,2:65,3:50"

then "3:43,2:65,3:50".gsub(':',' ').split(',') will return an array
containing:

["3 43", "2 65", "3 50"]

If they're two columns of a database, then this will probably be more
helpful:

rows = @selected_ciid_and_asso_types.split(',').map {|e| e.split(':')}
=> [["3", "43"], ["2", "65"], ["3", "50"]]

You could also change the last bit to e.split(':').map {|s| s.to_i} if you
wanted [[3, 43], [2, 65], [3, 50]] instead.

Hi,

rows = @selected_ciid_and_asso_types.split(',').map {|e| e.split(':').map
{|s| s.to_i}}
rows.each do |r|
obj = make_obj_somehow()
obj.ci_id, obj.service_desk_ci_id = r
end

Something like this?

Hi there,

For Rails, try Agile Web Development with Rails: A Pragmatic Guide - it got
me off the ground in Rails, but you'll still need to put in effort to grasp
the situation clearly. Learning the ins and outs of Ruby is important. :)

Consider the new book:

The Ruby Programming Language

One of the authors, David Flanagan, previously wrote 'the' book for
Javascript programming, so I would expect this book to be top notch.
