将数组写入文件ruby

Question

I have array of brands.

And I have this code:

brands.each_with_index do |brand, index|
  File.open('brands.txt', 'w') { |file| file.print  "#{brand.name} - #{brand.url}" }
end

So I want to write all brands into file but as a result I get only last brand, something like this:

Biomill - htttp://site.com/brand/biomill/dogs/

It seems like my file is being rewritten in the loop. What do I do?

Answer 1

You almost had it!

File.open('brands.txt', 'w') do |file| 
  brands.each_with_index do |brand, index|
    file.print "#{brand.name} - #{brand.url}" 
  end
end
