two things look suspicious:
1) /d+/
2) reverse

have you tried randomly rearranging your arrays first?

You're missing that String#[] when given a Regexp returns the substring that 
matches that Regexp.

[1] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| x[/\d+/]}
=> ["1020", "950", "50"]
[2] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| x[/\d+/]}.sort
=> ["1020", "50", "950"]
[3] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| x[/\d+/]}.sort.reverse
=> ["950", "50", "1020"]
[4] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| 
x[/\d+/].to_i}.sort.reverse
=> [1020, 950, 50]
[5] pry(main)> ["AB_1020", "AB_950", "AB_50",].sort_by {|x| x[/\d+/].to_i}
=> ["AB_50", "AB_950", "AB_1020"]

But [["AB_1020", "AB_950", "AB_50"], ["1000", "570"]] has non numerical

flat_map: https://apidock.com/ruby/Enumerable/flat_map

Then that passes a block, which acts on each member of the Enumerable that 
called flat_map. That block sorts by the numerical value of x, then reverses.

Does that help?

[Rails] Can you plz, explain to me part of this code ?

2018-04-26 Thread Abdel Latif

Hi,

I found this code for sorting an array :

p ["AB_1020", "AB_950", "AB_50", "1000", "570"].partition{|x| x.to_i.zero? }
  .flat_map{|x| x.sort_by {|x|x[/d+/]}.reverse}

ouptut

#⇒ ["AB_50", "AB_950", "AB_1020", "570", "1000"]



I know that .partition{|x| x.to_i.zero? } will create an array of arrays :
[["AB_1020", "AB_950", "AB_50"], ["1000", "570"]]


But this part .flat_map{|x| x.sort_by {|x|x[/d+/]}.reverse}

I could understand it.

Thanks.
