Extra desktop/mobile selector is appearing while browsing	Can't Post

Hi, i have a perl module that detects the device and adds an extra desktop/mobile selector accordingly (test.html -> test.desktop.html). Now, whenever I am moving from one page to another and extra selector is appending (test.desktop.html -> test2.desktop.desktop.html) and because of which I am getting error due to non-existing pages. I want my code to be modified so that if a selector is already present it must not append it again. Given below is the portion doing the above-mentioned task :-

Code

if ($model_group) { 
                                splice @uri_elements, 1, 0, $model_group; 
                                my $new_uri = join('.', @uri_elements); 
                                debug("New URI: ", $new_uri); 
                                $r->uri($new_uri); 
                        }

One way could be to put a condition around the splice.

Code

splice @uri_elements, 1, 0, $model_group unless @uri_elements[1] eq $model_group;

This ensures the splice isn't performed if the second uri element is equal to the model group. A regexp may be more suitable if you need to check against multiple model groups:

Code

splice @uri_elements, 1, 0, $model_group unless @uri_elements[1] =~ /^(mobile|desktop)$/;

Lastly, the condition could be better positioned in your code, but I didn't want to hinder the rejoining of the uri elements / updating the uri, inevitably I am uncertain of your intentions beyond this specific problem.

@Zhris : I modified the slice statement but that doesn't seems to be working for me. Please let me know if you need further inputs from my end to assist me better on this?

Perhaps you have to check all the @uri_elements,

Code

use List::Moreutils qw(none); 
# 
# 
if (none {$_ eq $model_group} @uri_elements) { 
    splice @uri_elements, 1, 0, $model_group; 
}

Good Luck,
Bill
