I have multiple contact datas in my website that I want to include in a single .vcf file to download. I implemented it one by one but I want to add the option to download all the contacts together not one by one.
Is possible to implement a method to download all the contacts at once in a single .vcf file? or I see other possibility. Make a function that receives a list of contacts and makes and vcard for each one, but the problem is that I have to save it in a buffer and then make a .zip or .rar file with all vcards and then download it. But I don't know how to implement it.
How can I do it using rails and vpim gem or other gem? thanks
UPDATE
I wrote a post explaining my solution. http://tomasmax.blogspot.com.es/2011/12/modificar-la-gem-vpim-para-introducir.html
