I have a question regarding routes for resources that have the same  
name in the singular and plural. For example, if I have:

map.resources :series do |series|  
series.resources :characters  
end

then ‘new\_series\_url’ generates ‘/series/new’, however I get the  
following error when I hit that url:

series\_url failed to generate from {:action=\>“show”,  
:controller=\>“series”} - you may have ambiguous routes, or you may  
need to supply additional parameters for this route. content\_url has  
the following required parameters: [“series”, :id] - are they all  
satisifed?

I’m presuming here it assumes I want the url for an existing series.  
I am able to create series if I use a singleton resource, e.g.:

map.resources :series

however, this fouls up the nesting of my characters resource causing  
‘new\_character\_url(:series\_id =\> @series)’ to generate the following  
url:

[http://localhost:3000/series/characters/new?series\_id=16](http://localhost:3000/series/characters/new?series_id=16)

which makes some sense, as I’ve now said series is a singleton  
resource. So, my question is how do I disambiguate between series  
(plural) and series (singular) when using non-singleton resources and  
generated url helpers to get properly nested resources?

Thanks,

pt.
