Symfony2项目-app_dev.php可以工作，但是app.php在特定页面上具有重定向循环

Question

I'm not entirely sure what is happening as it's the first time I've encountered this kind of problem, but for some reason, one particular page in my Symfony2 project has a redirect loop on app.php but when on app_dev.php, it's fine.

The page is called /files and the routing for this page is as follows:

app_files_table:
    path: /files
    defaults: { _controller: AppBundle:File:list }

The controller method for this page is pretty simple:

public function listAction()
{
    $em = $this->getDoctrine()->getManager();
    $documents_repo = $em->getRepository('AppBundle:Documents');
    $documents = $documents_repo->findAll();

    return $this->render('AppBundle:tables:files.html.twig', array(
        'files' => $documents
    ));
}

The twig template is just a standard layout which matches all my other pages (extending my base file which is the header) with the following code in the main body:

{% if files is not empty %}
{% for file in files %}
    <tr>
        <th scope="row">{{ file.id }}</th>
        <td>{{ file.name }}</td>
        <td>{{ file.displayName }}</td>
        <td>{{ file.product.model }}</td>
        <td class="text-center">
            <a class="btn btn-primary" href="{{ file_path }}/{{- file.name -}}" target="_blank" download><i class="fa fa-download"> </i></a>
            <a class="btn btn-danger file-delete" data-confirm-title="Are you sure?" data-confirm-message="You will not be able to undo this action." href="javascript:deleteFile({{ file.id }});" id="delete_file_{{ file.id }}" data-toggle="tooltip" title="Remove File"><i class="fa fa-remove"> </i></a>
        </td>
    </tr>
{% endfor %}
{% else %}
<tr>
<td colspan="5">There are no files in the database</td>
</tr>
{% endif %}

I have not edited the app.php, app_dev.php nor the .htaccess files - they are as they were when the framework was installed. I have also cleared the cache twice including removing all cache files manually - yet the redirect problem still occurs.

Is this something that others have encountered and managed to solve? Because I am confused as to why it should be happening on this page - in fact, I even tried putting a die() statement in the controller BEFORE the template is rendered, yet the same thing happens so it must be to do with the routing?

Any help appreciated.

Thank you

I recommend you to rebuild your bootstrap cache, you can do it via composer scripts, since its production you could do:

composer install -o --no-dev

Or simply

composer run-script post-install-cmd

You may also consider to remove the entire cache directory and delete the app/bootstrap.php.cache file.

If it doesn't work we will need more information, like config files, environments, logs, etc.
