Rails external URL work as a link in views

In my rails app, I have added a string that users can add the link to there facebook profile, it's a simple text field, but in the view I want them to have a link.

For example, if the user adds www.facebook.com/example I want it to appear as a link in the views for that I have tried the link_to approch but instead of pointing a link to the users profile it just refresh the page.

This is what I tried

<%= link_to(@user.fblink) %>

migration

class AddFblinkToUsers < ActiveRecord::Migration
  def change
    add_column :users, :fblink, :string
  end
end

user controller prams

def user_params
  params.require(:user).permit(:description, :avatar, :location, :fblink, :twlink, :ytlink, :username)
end

If your form is inserted data properly then, You can work on defining a helper class for link like

#=> helpers/application_helper.rb
def fb_link(user_fb)
    link_to "Facebook", "#{url_with_protocol(user_fb)}", class: "your-class", target: "new"
end
#=> url helper
def url_with_protocol(url)
    /^http/.match(url) ? url : "http://#{url}"
end

Then from view

= fb_link(@user.fblink)

Or you can work like this 

= link_to "Facebook", "#{url_with_protocol(@user.fblink)}", class: "your-class", target: "new"

Hope it helps

Try <%= link_to 'Facebook', @user.fblink %>

The first parameter of link_to method will display the value of the link. In this case it is Facebook. The second parameter is the url_path. When user click to the Facebook link it will go the url_path. In this case it is @user.fblink.

it will not work as link untill unless its not been saved as http,

for example if you want Facebook link to work its should be saved in db as https://www.facebook.com/example

so here for this you need a jquery form validation on your form input field:

and after that in your view page simply you can use it like

my link <%=@[email protected]%>

do not use link_to or any rails view helper here as its complete link is been alredy saved in database.

<script>
$( "#myform" ).validate({
  rules: {
    field: {
      required: true,
      url: true
    }
  }, 
 message: {
   field:{ required: 'fb link can't be blank!', url: 'Please enter valid url'}
  }
});
</script>
