[Ironruby-core] IronRubyMvc Filters and View Helpers
regarding helpers. You need to open up a class and add your methods there.
module System::Web::Mvc::IronRuby::Helpers
class RubyHtmlHelper
def menu_link(text, url, key, route_value_key=:controller)
if key.to_s.underscore
=view_context.route_data.values[route_value_key].underscore
"<li class=''current_page_item''><a
href=''#{url}''>#{text}</a></li>"
else
"<li><a
href=''#{url}''>#{text}</a></li>"
end
end
def login_menu_link(login_text="Log in", logout_text="Log
out",
login_action=:log_on, logout_action=:log_off, controller=:account)
text, act = view_context.controller.is_authenticated? ? [logout_text,
logout_action] : [login_text, login_action]
menu_link text, "/#{controller}/#{act}", controller
end
def format_chat_body(chat_body)
encode(chat_body).gsub("\n", "<br />")
end
end
end
You can define filters in multiple ways, and the way you''ve chosen is
only
there for working with legacy filters (legacy as in written in C# :)).
for example to implement the AuthorizationFilter you can do so by
implementing the following class
class RubyAuthorizationFilter < AuthorizationFilter
def on_authorization(context)
# put authorization logic here
end
end
and then in the controller you do
filter RubyAuthorizationFilter
or you could do it in a more rubyesque way
authorized_action :index do |context|
# add authorization logic here
end
from then on that controller requires authorization to get to its actions.
The latter uses the built in AuthorizationFilter too but tucks it away.
If you''re curious as to how this works:

Hope this helps

[Ironruby-core] IronRubyMvc Filters and View Helpers
You should be able to put the helper files you create in the helpers, that folder is added to the load path so it should work.ASP.NET MVC uses extension methods for its helper classes, when I was implementing that stuff for IronRubyMvc extension methods weren''t supported yet. --- Met vriendelijke groeten - Best regards - Salutations Ivan Porto Carrero GSM: +32.486.787.582 Blog: http://flanders.co.nz Twitter: http://twitter.com/casualjim Author of IronRuby in Action (http://manning.com/carrero) On Sun, Aug 23, 2009 at 5:43 AM, Shay Friedman <shay.friedman at gmail.com>wrote:> Hi Ivan, > > Is it possible to put the RubyHtmlHelper code in a file under the Helpers > directory? > > Another MVC question - I tried to use alias_action but couldn''t get it to > work.
