Accessing PageRenderRequestParameters in a component / Localized URL
Hello,
Just wondering if you have a way to access the PageRenderRequestParameters inside a component.
I am building a LocalePageLink component for SEO purpose, that translates the current page url into its localized version, instead of using a locale toggle with an action link.
I need it for SEO friendly language switcher but also for alternate href.
My component is working correctly, and will render
<a href="#" t:type="LocalePageLink" t:id="localeEN" locale="en" page="mypagename” context=“1"> EN </a>
will render: /en/mypagename/1 for locale en
<a href="#" t:type="LocalePageLink" t:id="localeFR" locale=“fr" page="mypagename” context=“1"> EN </a>
will render: /en/mypagename/1 for locale fr
But I want my component to be smarter and deduce the page name, context and parameters from the current url if they are not specified to the component.
I know how to get the page name using componentResources, but I didn’t find a way to get the activation context and the context parameters without parsing the url.
On the same subject I would like to have better page name than the “java” page name. For example if my page name is BuyTicket.java I would like to have
/en/buy-concert-ticket in english
/fr/acheter-tickets-concert in french
… and so on.
So I would like to localize page names in url, and eventually improve the name for SEO purpose, do you know where should I hook ?
I would be happy to share my components once they are functional.
Thank you for your help,
Numa

Hi Ben,
Thank you for your help. Very useful.
I used the same technic with tapestry 4 I had encoder to slugify my objects and keeping the id at the end. I am always wondering if it’s better to have a slug without an id, or with an id.
I think that keeping an id is more robust on the long run.
Best
Numa

Hi,
for custom URLs you could use
org.apache.tapestry5.services.linktransform.PageRenderLinkTransformer
It's responsible for transforming/decoding
PageRenderRequestParameters/Requests.
This ensures that generated links will be correct, too.
The only problem here would be the actual mapping between the path and the
actual page / parameters, and vice-versa.
Usually, the path contains some kind of unique identifier, making the
actual name in the path more flexible.
Medium has a hash at the end to actually identify the correct story, not
the full path.
Amazon has the product title in the URL, even though it can be changed
freely, and it still works due to the rest of the path.
It all depends on the purpose of the pages, and how often URLs change or
are added.
Is it a lot of dynamic content, e.g., article or product pages? An added
identifier should be subtle and easier to manage.
Is it a static page, e.g., checkout page? A fixed lookup map might be more
sensible.
And you should also consider what is supposed to happen if something is
mixed up, e.g. missing locale (/acheter-tickets-concert), or wrong locale
(/fr/buy-concert-ticket).
These are some of the problems we ran into with our multi-Locale system, I
hope this helps a little.
Cheers
Ben

Yes, you can do it this way:
@Inject
private PageRenderLinkTransformer linkTransformer;
@Inject
private RequestGlobals requestGlobals;
PageRenderRequestParameters requestParameters =
linkTransformer.decodePageRenderRequest(requestGlobals.getRequest());
