Symfony3: How to set multiple connections? - php

Question

I'm working with a Symfony3 app and I want to set up multiple connections to different databases.
I've been looking around and I found out the documentation about entityManagers and DB connections. My config.yml is configured as follows:
config.yml
doctrine:
dbal:
default_connection: default
connections:
default:
driver: pdo_mysql
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
charset: UTF8
mapping_types:
enum: string
other:
driver: pdo_mysql
host: "%database_host2%"
port: "%database_port2%"
dbname: "%database_name2%"
user: "%database_user2%"
password: "%database_password2%"
charset: UTF8
mapping_types:
enum: string
orm:
dql:
string_functions:
DAY: DoctrineExtensions\Query\Mysql\Day
MONTH: DoctrineExtensions\Query\Mysql\Month
YEAR: DoctrineExtensions\Query\Mysql\Year
auto_generate_proxy_classes: "%kernel.debug%"
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
So now I do can access to my database like this:
$con2 = $this->get('doctrine.dbal.other_connection');
$orders = $con2->fetchAll('SELECT * FROM orders');
But what I really need is to configure a second orm-mapping connection which will allow me to interact with entities instead of dealing with the second database directly. So again as the documentation says I added under the doctrine orm label:
orm:
dql:
string_functions:
DAY: DoctrineExtensions\Query\Mysql\Day
MONTH: DoctrineExtensions\Query\Mysql\Month
YEAR: DoctrineExtensions\Query\Mysql\Year
auto_generate_proxy_classes: "%kernel.debug%"
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
default_entity_manager: default
entity_managers:
default:
connection: default
mappings:
AppBundle: ~
other:
connection: other
mappings:
OtherBundle: ~
This throws an exception:
ParseException in Parser.php line 296:
Unable to parse at line 78 (near " entity_managers:").
How should I configure my config.yml to allow orm-mapping for my second database connection? Should I delete the dql label and use it only under a certain entity manager label?

Answer 1

check the doc here for full reference of the configuration about doctrine.
Check the indentation of the dql function etc.
Probably us are using the Shortened Configuration Syntax where all options available can be placed directly under doctrine.orm config level.
Hope this help

Answer 2

Try this one:
doctrine:
orm:
auto_generate_proxy_classes: true
entity_managers:
default:
mappings:
AppBundle: ~
naming_strategy: doctrine.orm.naming_strategy.underscore
dql:
string_functions:
DAY: DoctrineExtensions\Query\Mysql\Day
other:
mappings:
OtherBundle: ~

Answer 3

I solved the problem. Thanks for the answers because they were pretty much the solution. I just had to use the labels in their correct levels.
Just in case it can be useful for someone, I'll post what I've done:
config.yml
orm:
entity_managers:
default:
mappings:
AppBundle: ~
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
dql:
string_functions:
DAY: DoctrineExtensions\Query\Mysql\Day
MONTH: DoctrineExtensions\Query\Mysql\Month
YEAR: DoctrineExtensions\Query\Mysql\Year
other:
mappings:
OtherBundle: ~
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_generate_proxy_classes: "%kernel.debug%"
Once the (other) entity manager is created you just can use it within a controller as you'd do with the default em just by specifying the entity manager name you are using.
$orders = $this->get('doctrine')
->getRepository('OtherBundle:Orders', 'other')
->findAll();
Now you're ready to go.
Thanks for your help.
