Hi Abdel, sorry for the confusion, I guess I didn't explain myself properly. `orders` would be a collection composed by instances of Order model. For example, imagine you do `Order.last(5)` to get the last 5 orders. I hope this clarifies the example. Cheers, Alberto 2018-05-16 18:50 GMT+02:00

Hi Anthony, thanks for your response. Great that you mention this. Yes I have seen other Rubyists on the internet proposing a similar solution, but for me it feels like a workaround, which could work in some cases, but it's not ideal. My main objection for that is that it implies defining

Re: [Rails-core] [Feature] Symbol to_proc coercions: Enumerable#map can take several symbols

On reading my first thought was "can you do that by defining to_proc on Array". A brief play suggests one can: class Array   def to_proc     Proc.new { |arg| self.inject(arg) { |memo, f| f.to_proc.call(memo) } }   end end

Re: [Rails-core] [Feature] Symbol to_proc coercions: Enumerable#map can take several symbols

Hi Rafael, I'm glad to see you here. The reason I see its place here at first is because I think its use case fits better with the framework than with the language. When thinking on the Ruby language I would expect more to deal with collections which contain objets like String, Integer, and

If you think that method would be useful there is no reason why it should be Rails specific. Please send a feature request to the Ruby issue tracker here  https://bugs.ruby-lang.org/. Rafael França On May 11, 2018, 13:10 -0400, Alberto Almagro , wrote: > These days I

[Rails-core] [Feature] Symbol to_proc coercions: Enumerable#map can take several symbols

These days I have been comparing records in my daily job lots of times, which made me think about a better way to retrieve and compare them. When I want to navigate through several relations in a collection I often see myself writing code like the following: Given orders as a collection of
