Q:

Symfony / Orocrm : yml file is not set?

Website : Open source frameword based on Symfony 2.7
My entitie : Entity/Download.php (with properties "id", "creation_date" and "name")
I'm working on my own Bundle and I try to create a new datagrid based on my own entitie, I follow this tutorial. Below is what I've done :

Create /resources/config/datagrid.yml, with a very light datagrid.
Edit DependencyInjection/MyBundleExtension.php to load datagrid.yml.
Edit my twig view to render the datagrid :

{% import 'PimDataGridBundle::macros.html.twig' as dataGrid %}
{% block content %}
  {{ dataGrid.renderGrid('custom_download', { localeCode: locale_code() }) }}
{% endblock %}

But this error is generated :

Twig_Error_Runtime: "An exception has been thrown during the rendering
  of a template ("A configuration for "custom_download" datagrid was not
  found.

-> If I try the same code with another gridname already existing that works then I believe the problem comes from my new datagrid but I don't understand what's wrong : does the kernel include my YML config file ? I don't think so.
Thanks for your help.

A:

You create datagrid.yml in /resources/config folder.
But according OroPlatform conventions configuration file should be placed in Resources/config/oro folder of your bundle and named datagrids.yml.
Exactly in this path OroPlatform is looking for datagrid configuration.
https://github.com/oroinc/platform/blob/2.5/src/Oro/Bundle/DataGridBundle/Provider/ConfigurationProvider.php#L154-L160
Please move your configuration into correct directory and filename. And It will be work. And of course you should remove this file loading from DependencyInjection/MyBundleExtension.php OroPlatform do it automatically.
For more detailed understanding how you can use OroPlatform datagrid features please read bundle documentation
