v1.2.6 - Show latest stable - 0 notes - Class: ActionView::Helpers::UrlHelper

link_to_unless(condition, name, options = {}, html_options = {}, *parameters_for_method_reference, &block) public

Creates a link tag of the given name using a URL created by the set of options unless condition is true, in which case only the name is returned. To specialize the default behavior, you can pass a block that accepts the name or the full argument list for link_to_unless (see the example).

  <%= link_to_unless(@current_user.nil?, "Reply", { :action => "reply" }) %>

This example uses a block to modify the link if the condition isn’t met.

  <%= link_to_unless(@current_user.nil?, "Reply", { :action => "reply" }) do |name|
     link_to(name, { :controller => "accounts", :action => "signup" })
   end %>
