How to link ResourceTemplates to Resources

[barryvdh]

It feels like I'm missing a step, but how do you return the data from a ResourceTemplate?

For example, let's say I have 'users'. So I would create:

UserListResource
uri = database://users

And a UserResourceTemplate
uri = database://users/{id}

And then what? Where do I return the details for my users?

I would expect I can return an array of users with basic information + id + perhaps the URI to the detailed info. But the ResourceTemplate doesn't contain a read() function.
Should I create my own ResourceRepository and implement the URI parsing myself?

I feel like I should be able to implement a read(array $parameters) function in my ResourceTemplate, but not sure if I'm missing something, or it's just not implemented yet..

I tried playing with https://symfony.com/doc/current/create_framework/routing.html
Which is what Laravel users, but you'd probably have to tweak it a bit for the scheme. Something like this in the ResourceRepository

public function read(string $uri): ?array
    {
        $resource = $this->resources[$uri] ?? null;
        if ($resource) {
            return $resource->read();
        }

        // Check the requested scheme
        $scheme = uri($uri)->scheme();

        try {
            $routes = new \Symfony\Component\Routing\RouteCollection();
            foreach($this->templates as $key => $template ) {
                if (uri($template->uriTemplate)->scheme() === $scheme) {
                    $uriTemplate = Str::replaceFirst($scheme.'://', '/', $template->uriTemplate);
                    $routes->add($key, new \Symfony\Component\Routing\Route($uriTemplate));
                }
            }

            if ($routes->count() === 0) {
                return null;
            }

            $context = \Symfony\Component\Routing\RequestContext::fromUri($uri);
            $matcher = new \Symfony\Component\Routing\Matcher\UrlMatcher($routes, $context);

            $params = $matcher->match(Str::replaceFirst($scheme.'://', '/', $uri));
        } catch (\Symfony\Component\Routing\Exception\ResourceNotFoundException $e) {
            return null;
        } catch (\Throwable $e) {
            throw $e;
        }

        return $this->templates[$params['_route']]->read($params);
    }

And then you can call function read(array $params) {} in each ResourceTemplate

@barryvdh Thank you for the feedback — I will look at it soon.
