Rails2. If a route has already been established with “map.resources”,  
is there any way I can add an additional member to it, without  
over-writing what’s already there?

This comes up in two engines-style plugins interacting with each other  
and with the app itself.

Just define the route as you normally would (with map.connect ).  
map.resources is not magical; it’s just shorthand for a bunch of  
map.connect statements.

Ah, i was worried that my second map.resources would ‘over-ride’ certain  
things from the first one. But it looks like it doesn’t. If you call  
map.resources once with certain :members, and then call it again with  
another :member… it LOOKS like indeed all the aggregated members are  
now there. Cool. Thanks.

Interesting to know. I’d tend to only call map.resources once and then  
use map.connect, but it’s good to know that it works either way.
