Question

I have this model:

class Story < ActiveRecord::Base
    validates_presence_of :name , :link
end

Where a validation for a form take place. But I want also to validate if the string “http” is included in the :link symbol. I can’t do :link.include? because :link is symbol. How do I do that?

My View is this:

<% form_for :story do |f| %>
<p>
  name:<br />
  <%=f.text_field :name %>
</p>
<p>
  link:<br />
  <%= f.text_field :link %>
</p>
<p>
  <%= submit_tag :"submit this story" %>
</p>
<% end %>

Answer 1

If you add in a validates_format_of you can supply a regex to test the link with.

class Story < ActiveRecord::Base
    validates_presence_of :name , :link
    validates_format_of :link, :with => /^http.*$/
end
