# Below are some hacks to Rails internal classes that implement Instiki URLs scheme.
|
|
# It is no doubt a bad practice to override internal implementation of anything.
|
|
# When Rails implements some way to do it in the framework, this code should be replaced
|
|
# with something more legitimate.
|
|
|
|
# In Instiki URLs are mapped to the ActionPack actions, possibly performed on a particular
|
|
# web (sub-wiki) and page within that web.
|
|
#
|
|
# 1. Controller is determined by action name (default is 'wiki')
|
|
# 2. '/name1/' maps to action 'name1', unspecified web
|
|
# Example: http://localhost/new_system/
|
|
# 3. Special case of above, URI '/wiki/' maps to action 'index', because Rails sets this address
|
|
# when default controller name is specified as 'wiki', and an application root
|
|
# (http://localhost:2500/)is requested.
|
|
# 4. '/name1/name2/' maps to web 'name1', action 'name2'
|
|
# Example: http://localhost/mywiki/search/
|
|
# 5. '/name1/name2/name3/' maps to web 'name1', action 'name2',
|
|
# Example: http://localhost/mywiki/show/HomePage
