Solr Batch export should use route instead of hardcoded path for redirection

Created on 28 May 2025, 2 months ago

Problem/Motivation

On some projects, it may occur that the /admin paths are rewritten to something else (e.g. on a project, we use https://www.drupal.org/project/rename_admin_paths → to override "/admin" with "/administration").
When doing so, any hard-coded path will result into a 404 error because the overriding usually happens on route_alter.

Steps to reproduce

- Install https://www.drupal.org/project/rename_admin_paths → and navigate to '/admin/config/system/rename-admin-paths' to rename the admin path to something else (e.g. "administration").
- Install and configure SOLR Search Synonym
- Navigate to the list page of SOLR synonyms
- Click the "Import to Solr" button
- You should end up on a 404 page instead of the batch page.

Proposed resolution

In SolrSynonymUploaderBatchExport.php, replace :
$redirect_url = '/admin/config/search/solr-search-synonyms';
with :
$redirect_url = Url::fromRoute('entity.solr_search_synonym.collection')->toString();

It will solve the above problem and be more robust if the route path should change in the future for any reason.
Attached is a patch for immediate use.
