Can someone give me a leg up? I’m finding it difficult to find the  
request.params array anywhere within the Page context. I have setup a  
custom route as part of my extension (not for the admin area, but for  
the main site) and in that route I have mapped some custom params I  
really want to access.

Any ideas… I tried tag.local.parms[], tag.page.param[],  
@request.param[], etc.

Looking through the models/page.rb and taggable I don’t see any place  
I’d get this from, but I’m hoping I’m missing something.

Thanks,

If you’ve made a custom route, then that route will be handled by a  
regular rails controller, not a page object.

No, I get that. Here is my custom route:

map.connect ‘event-  
calendars/:calendar\_group/:calendar/:period’, :controller =\>  
‘site’, :action =\> ‘show\_page’, :url =\> ‘calendar’

So I’m forward the control back to the Radiant Site controller.

My question is within the Page type which I attach to the real  
Radiant page found at “/calendar” how can I cleanly access the url  
params ? This is how I solved it for now, but it’s ugly and inflexible:

class EventCalendar \< Page  
…  
tag “calendar” do |tag|  
path = @request.request\_uri.split("/")  
p = Hash[:calendar\_group =\> path[2], :calendar =\> path  
[3], :period =\> path[4]]  
…  
end  
end

Just hoping to find a better way.

Thanks,

Hmmm… seems that tags ARE instance\_eval’d on the page, so ignore my  
last email. You’re after params as interpreted by controllers. I think  
those are available with @request.path\_parameters

The @request object is made available to a Page, but the tags are not  
evaluated within the context of a page. If you have a method on your  
page such as:

class MyPage \< Page  
def monkeys  
@request.params[:monkeys]  
end  
end

Then you could reference that from your tag:

tag ‘monkeys’ do |tag|  
tag.locals.page.monkeys  
end
