{ActionController] Default route naming

Rails
1

I have discovered that if a named resources entry does not have a plural
form then ActionController::Routing uses route_name_index instead.
However, I cannot seem to find any place in the API where this is
mentioned. Can somebody point out to me where this behaviour is
specified?

Are you talking about singular resources?

If not, you may want to show how you’re declaring your route…

I am not talking about singular resources.

map.resources :forex,
:type => ‘CABK’,
:controller => ‘currency_exchange_rates’,
:only => [:index, :show]

$ rake routes
…
forex_index GET /forex(.:format) {:action=>“index”,
:controller=>“currency_exchange_rates”}

  forex GET    /forex/:id(.:format) {:action=>"show",
                                     :controller=>"currency_exchange_rates"}

Looks fine to me…what are you expecting the route to be?

Yes, I confused myself by using both named routes and resources. That
and I got caught by Rails inflection system as forex has no plural so
that the index action becomes forex_index GET, rather than forexes GET.

I ended up with this sort of thing instead:

map.forex_by_currency_and_date
‘/forex/:currency_code/:year/:month/:day’,
…

map.forex_by_currency
‘/forex/:currency_code’,
…

map.forex_by_date
‘/forex/:year/:month/:day’,
…

map.resources :forex,
:type => ‘CABK’,
:controller => ‘currency_exchange_rates’,
:only => [:index, :show]

Note that because forex has no plural form registered in inflections

the generated index route is named forex_index
