Understanding Routing and Redirects

Hello,
Seems like routing should be simple in Nette, but it's just confusing me.
The url structure example is:
chinese-dvd-cover-scan/387/portland-street-blues
My route is:
$router->addRoute('chinese-dvd-cover-scan[/<id \d+>]<title>', 'CoverScan:default');
When clicked I'm seeing the following in the address bar:
cover-scan/default/387?title=portland-street-blues
Can someone explain what is happening with the name being trimmed (related to presenter name maybe?) and why does ‘default’ appear? And how do I keep the same structure when clicked? So, basically what should the correct route be?
Many thanks.

@kodama Try with
$router->addRoute('chinese-dvd-cover-scan[/<id \d+>/<title>]', 'CoverScan:default');
Square brackets denote optional parts of the route – I am not sure, if
you want to also support just bare URL chinese-dvd-cover-scan
. If
that is not the case (and <id>
and <title>
have to always be present), then route would look like
$router->addRoute('chinese-dvd-cover-scan/<id \d+>/<title>', 'CoverScan:default');
.
Also pay attention to order of the routes – you want to place specific
routes (like your route above) first, general routes (something like
<presenter>/<action>
) last, because routes are
evaluated sequentially and the first matched route is used. So when you have a
general route on the first position, it always gets matched and your more
specific routes are ignored.

In fact, the problem is not in that particular route, but in a previous one, which, being earlier, has a higher priority. The debugger can help you visualize this. More info about the order of the routes is in the documentation.

Actually, I'm still confused. Let's say I have this in the router file:
$router->addRoute(‘japanese-dvd-cover-scan[/<id
\d+>]/<title>’, ‘CoverScan:default’);
$router->addRoute(‘chinese-dvd-cover-scan[/<id
\d+>]/<title>’, ‘CoverScan:default’);`
If you go to:
chinese-dvd-cover-scan/1807/18-secrets-of-kung-fu
It shows:
japanese-dvd-cover-scan/1807/18-secrets-of-kung-fu
So, it always shows the first route. Why does ‘chinese-dvd-cover-scan’ match the first route?

Ask yourself: if id=1807
and
title=18-secrets-of-kung-fu
, which link should be generated? Both
can be used, Nette cannot distinguish between them, so it generates the
first one.
If the user comes through the second one, Nette automatically redirects to the first (this is called autoCanonicalize, it's for SEO reasons, you can turn it off).
Maybe the solution is to make one route with mask
<lang>-dvd-cover-scan/<id>/<title>
