My string:
>> pp params[:value]
"07016,07023,07027,07033,07036,07060,07062,07063,07065,07066,07076,07081,07083,07088,07090,07092,07201,07202,07203,07204,07205,07206,07208,07901,07922,07974,08812,07061,07091,07207,07902"
How can this become an array of separate numbers like :
["07016", "07023", "07033" ... ]
result = params[:value].split(/,/)
String#split is what you need
Try this:
arr = "07016,07023,07027".split(",")
Note that what you ask for is not an array of separate numbers, but an array of strings that look like numbers. As noted by others, you can get that with:
arr = params[:value].split(',')
# Alternatively, assuming integers only
arr = params[:value].scan(/\d+/)
If you actually wanted an array of numbers (Integers), you could do it like so:
arr = params[:value].split(',').map{ |s| s.to_i }
# Or, for Ruby 1.8.7+
arr = params[:value].split(',').map(&:to_i)
# Silly alternative
arr = []; params[:value].scan(/\d+/){ |s| arr << s.to_i }
params[:value]is irrelevant to the question and is misleading.
