:member resources actions and :requirements

Hi!

I’m having a bit of trouble with routes requirements for resources.
Using Rails 2.0.2, I tried to specify that an explorer id (which
actually is its login as a permalink) could contain dots, minus, or
underscores thanks to requirements :

##################################################
######## config/routes.rb
map.resources :explorers,
:requirements => { :id => /[\w.-_]+/},
:collection => { :search => :post}
:member => { :languages => :any,
:map => :get}

####### a/models/explorer.rb

class Explorer < ActiveRecord::Base
def to_param
login
end
end

##################################################

For explorers without ‘.’ in their login, every route works fine and

explorers
explorers/john
explorers/john/map

are all recognized.

But for example :

explorers/john.doe
will get recognized while
explorers/john.doe/map
will raise:

Routing Error

No route matches “/explorers/john.doe/map” with {:method=>:get}

It seems like :requirements option is only taken into account for
basic resources actions, not the one that have been added via :member.

Is there a way to force :requirements for :member actions, or do I
have to write usual routes individually and map them to
“#{action}_explorer”?

Thanks a lot for your attention & have a nice week-end,

Eric
