FOS Elastica manual provider service injection issue - php

Question

I am trying to create a manual provider to manually populate my FOS Elastica index to account for some complex joins. At the moment, I am just trying to get the provider to work even without the joins, and I am having trouble injecting the correct Elastica Type into my constructor for the provider. Here is the constructor of my provider:
// ...
class EmpPosDeptProvider implements ProviderInterface
{
private $em;
protected $type;
public function __construct(Type $type, EntityManager $em)
{
$this->type = $type;
$this->em = $em->getRepository('CcitEmployeesBundle:Position');
}
// ...
and here is my services.yml file:
services:
employees.search_provider.empPosDept:
class: Ccit\EmployeesBundle\Search\EmpPosDeptProvider
tags:
- { name: fos_elastica.provider, index: employees, type: empPosDept }
arguments:
- %fos_elastica.type.class%
- #doctrine.orm.entity_manager
When I try to execute php app/console fos:elastica:populate I am receiving the following error:
PHP Catchable fatal error: Argument 1 passed to Ccit\EmployeesBundle\Search
\EmpPosDeptProvider::__construct() must be an instance of Elastica\Type, string given,
called in /vagrant-nfs/employees/app/cache/dev/appDevDebugProjectContainer.php on line 736
and defined in /vagrant-nfs/employees/src/Ccit/EmployeesBundle/Search
/EmpPosDeptProvider.php on line 23
Does anyone know what I need to give as a correct argument in my services.yml file? Or could the problem be something else entirely?

Answer 1

You're passing a string containing Ccit\EmployeesBundle\Search\EmpPosDeptProvider. You have to pass an instance of EmpPosDeptProvider, and it may be declared in your services.yml something like:
services:
fos_elastica.type:
class: %fos_elastica.type.class%
employees.search_provider.empPosDept:
class: Ccit\EmployeesBundle\Search\EmpPosDeptProvider
tags:
- { name: fos_elastica.provider, index: employees, type: empPosDept }
arguments:
- #fos_elastica.type
- #doctrine.orm.entity_manager

Answer 2

Apparently I needed to provide the explicit path to the type I was referencing. The following line worked:
#fos_elastica.index.employees.employeePositionDepartment
This makes sense given that my config.yml file contains the following:
fos_elastica:
clients:
default: { host: localhost, port: 9200 }
indexes:
employees:
client: default
types:
employeePositionDepartment:
mappings:
id: { type: integer }
title: { type: string }
startDate: { type: date, format: date_time_no_millis }
endDate: { type: date, format: date_time_no_millis }
supervisor: { type: integer }
Thanks to anyone who was considering helping me with this rather elementary question.
