Infinite Possibilities
Rails routing is implemented using a DSLâa Domain-Specific Language. Ruby lets developers build all kinds of functionality into a very concise form, but at the same time, DSLs can become pretty mind-bending quickly. Routing in particular can grow extremely complicated if you try to take advantage of too many cool Rails features. There are many, many more possibilities than a Learning book can reasonably cover. Among them are:
Using
map.resources
with a blockCustom parameters and conditions
Abandoning numeric
id
values in favor of more descriptive unique namesMore precisely defined nested resources with path and name prefixes
Multiple levels of nesting
Testing routes with
assert_generates
,assert_recognizes
, andassert_routing
Debugging routes from the console
Extending routing
Once youâve run out of things to do with the possibilities explored in this chapter, and feel confident that you understand how Rails is routing requests, you can take the next steps forward into deepest Rails.
