Question

I’m new to ruby and feel that I still do a lot of things in C sharpish way :-). Suppose you have an array of objects (Question :has_many=>:answers). I want to iterate over all answers and if some answers meet a criteria, change answer attribute. Currently I’m doing it as follows:

def iterate_and_do_stuff    for (a in self.answers)       if(a.somecriteria==true)          a.some_attr=some_val       end    end end 

What are other ways of doing this? Blocks, loops, etc?

Please adivce.

Thank you.

Answer 1

Use Array#each:

self.answers.each {|a| a.some_attr = some_val if a.some_criteria}
