How to remove brackets and quotation marks from array Ruby

Question

I have the below class method:

def self.product(basket)
  Product.find(basket.to_a).collect do |product| 
    product.name + " " + product.size + " " + product.color
  end
end

The above produces the following:

["T-Shirt Medium Grey", "Sweatshirt Medium Black"]

I've tried the following:

def self.product(basket)
  a = Product.find(basket.to_a).collect do |product| 
    product.name + " " + product.size + " " + product.color
  end
  b = a.shift.strip
end

But this ends up only giving me the first part of the array T-shirt Medium Grey

I'm looking for it to give me

T-shirt Medium Grey, Sweatshirt Medium Black

Can anyone help?

Thanks

What is the output you are looking for?

Your problem is how to customize displaying array content. One of possible solution is converting to string using Array#join method:

a.join(', ')
# => "T-Shirt Medium Grey, Sweatshirt Medium Black"

This should work:

def self.product(basket)
  Product.find(basket.to_a).map{|product| [product.name, product.size, product.color].join(" ")}.join(', ')
end
