How to replace text in a ruby string

Question

I am trying to write a very simple method in Ruby which takes a string and an array of words and checks if the string contains any of the words and if it does it replaces them w

Answer 1

This will work better. It loops through the brands, searches for each, and replaces with the uppercase version.

brands = %w(sony toshiba)
sentence = "This is a sony. This is a toshiba."

brands.each do |brand|
  sentence.gsub!(/#{brand}/i, brand.upcase)
end

Results in the string.

"This is a SONY. This is a TOSHIBA."

For those who like Ruby foo!

sentence.gsub!(/#{brands.join('|')}/i) { |b| b.upcase }

And in a function

def capitalize_brands(brands, sentence)
  sentence.gsub(/#{brands.join('|')}/i) { |b| b.upcase }
end
