Rails - Mar 2007 - 500 when using url_for helper in controllers initialize

It seems like you can''t use the url_for helper in the initialize
method of a controller:

class TestController < ApplicationController
  def initialize
    @somevar = url_for ( :action => ''index'' ) #<=== This
errors out
for some reason
  end

  def some_method
    @somevar = url_for ( :action => ''index'' ) #<=== but
this works
  end
end

Any idea why this is happening? Is there a known work around?

Thanks

Rafael

Rather than initialize, try a before_filter

  class TestController < ApplicationController
    before_filter :set_some_var

    def index
      #renders index.rhtml
    end

    private
      def set_some_var
         @somevar = url_for ( :action => ''index'' )
      end
  end

Now you can use @somevar in every action that goes through your 
controller.

If you use/d named routes you can/could just use index_url instead of having
to assign a variable.
