Working With Rails

Http Url Validation Improved

HTTP URL Validation is a Rails plugin that allows you to validate a URL entered in a form. It validates if the URL exists by hitting it with a HEAD request. There’s the option to also check that the URL returns content of a specified type. Here’s how you can use it your model:

Check for content type: validates_http_url :url, :content_type => “text/html”

Do not check for content type, just make sure the site is accessible: validates_http_url :website

Make sure there is a DNS entry for a domain validates_http_domain :domain

1. Domain must be in ‘www.site.com’ for or ‘site.com’ form. No http://, no path.

This example will make sure the value entered for the URL field points to a publicly accessible HTML page, and the photo field points to an image: validates_http_url :image_url, :content_type => “image”

1. :content_type checks for a matching substring, so any image will validate
