I have a web-app made in Drupal 8, and I have some routing problems. Users will login using an external service, and after login they are sent to the path /user/{user}, where {user} is their user id. I want to change this behaviour and send them to a page /dashboard. Not having access to what the external service routing is doing, I need to reroute /user/{user} to /dashboard. It seems like the drupal 8 redirect module could solve the problem, but I am not too keen on using an external module just for this simple task.
Because of this, I tried to change the route with drupal's RouteSubscriber and alterRoutes method. So I made my RouteSubscriber class in my module called "module" like this:
class RouteSubscriber extends RouteSubscriberBase {
protected function alterRoutes(RouteCollection $collection) {
if ($route = $collection->get('user.page')) {
$route->setDefaults(array(
'_controller' => '\Drupal\module\Controller\Dashboard::content',
));
}
if ($route = $collection->get('entity.user.canonical')) {
$route->setDefaults(array(
'_controller' => '\Drupal\module\Controller\Dashboard::content',
));
}
}
}
The route user.page has path /user, and the path entity.user.canonical is the route I'm interested in, which has path /user/{user}, where {user} is again a path parameter. When I go to the page /user, the dashboard is displayed as expected, but going to for example /user/123 does not show the dashboard, but seems display what the route originally did. Just to test whether it was impossible to alter this route, I tried to set all routes to have display the dashboard by inserting the following code into RouteSubscriber:
foreach ($collection->all() as $route) {
$route->setDefaults(array(
'_controller' => '\Drupal\module\Controller\Dashboard::content',
'pid' => '',
'uid' => '',
'modifier' => '',
'display' => '',
));
}
The junk pid, uid, modifier and display are just defaults to different routes path parameters so the code will run. This makes the page /user/123 correctly display the dashboard! However, I do get the following error message at the bottom of the screen:
The website encountered an unexpected error. Please try again later.
Symfony\Component\Routing\Exception\MissingMandatoryParametersException: Some mandatory parameters are missing ("filter") to generate a URL for route "devel.configs_list". in Drupal\Core\Routing\UrlGenerator->doGenerate() (line 182 of core/lib/Drupal/Core/Routing/UrlGenerator.php).
So, what am I doing wrong here? Can what I want be done, or should I do something different to achieve what I want? Also, feel free to ask for more code if needed!
