Question

In my application I have websites being saved to a field called website that you can put the value of www.website.com or use http://www.website.com. I’m not sure how you make the http://www.website.com always look like www.website.com in the view.

If my model is Store and its table column is t.string :website. What would I put in my StoreHelper and view? Is it possible to change a string like this?

Answer 1

You can use regex to get rid of the http:// part:

@store.website.downcase.sub(/https?:\/\//, '')

Personally, I wouldn’t do it in a helper, but add a method to my model:

class Store < ActiveRecord::Base
  def website_without_http
    self.website.downcase.sub(/https?:\/\//, '')
  end
end

With this you can do:

<%= link_to @store.website_without_http, @store.website %>
