Split string

Ruby
1

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
This is working…But what I need is like
ci_id service_desk_ci_id

3 43
2 65
3 50

Then with in a for loop

@obj.ci_id=3
@obj.service_desk_ci_id=43

@obj.ci_id=2
@obj.service_desk_ci_id=65

@obj.ci_id=3
@obj.service_desk_ci_id=50

How can i do this ?

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 D. 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 P.ming Language

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