Troubles with URI class

[eluser]jakelehner[/eluser]
Hi all ... I've done some searching on here and haven't found an answer yet. I'm having a hell of a time with the ruri_to_assoc and uri_to_assoc functions, and hope someone can help me out here.

The following scenario happens both in CI 2.0.1 and CI 2.1.0.

I have the following route defined:

Code:

$route['user/(:any)'] = "user/index";

Obviously, the goal here is to not include the method (index in this case) in the URL string. The uri functions mentioned above don't seem to be working as expected. When I access the following URL:

/user/id/3/format/json (which routes to /user/index/id/3/format/json)

I get the following:

Code:

$this->uri->ruri_to_assoc()

generates

Code:

Array
(
    [3] => format
    [json] =>
)

and

Code:

$this->uri->uri_to_assoc()

generates

Code:

Array
(
    [3] => format
    [json] =>
)

I'm confused why ruri is returning the same as uri. Here's where it gets interesting ...

both of the following

Code:

$this->uri->ruri_to_assoc(1)
and
$this->uri->uri_to_assoc(1)

return

Code:

Array
(
    [user] => index
)

then

Code:

$this->uri->ruri_to_assoc(2)
and
$this->uri->uri_to_assoc(2)

both return

Code:

Array
(
    [index] =>
)

BUT ...

Code:

$this->uri->ruri_to_assoc(3)
and
$this->uri->uri_to_assoc(3)

both return

Code:

Array
(
    [3] => format
    [json] =>
)

wtf? Am I missing something here? It looks like the ruri and uri functions are doing the same thing. I also don't understand why it looks like both functions are counting the PRE-routed url (by counting 'index' as a segment) until I specify the start segment as 3 ... in this case BOTH functions decide to use the post route URL and view 'id' as the method rather than the first segment.

Please telling me I'm missing something easy here.

Ok ... I found my first problem. My route was wrong. I changed it to:

$route['user/(:any)'] = "user/index/$1";

and it *almost* works ...

now if I go in to the URI library and comment out the block of code that does the caching:

Code:

if (isset($this->keyval[$n]))
  {
   return $this->keyval[$n];
  }

it works ... but if I leave the cache block in, it does not.

Any ideas?
