I have an app that talks to two different databases. For one of my entities, School, I get the following error:
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'pressbox.schools' doesn't exist
That makes sense because there is no pressbox.schools. It's fnt.schools. It's trying to talk to the wrong database.
How do I tell my entity which mapping I want it to use? I would of course rather refer to the mappings than to the database names themselves, which can be different depending on the environment.
First, declare your connections in a config file (config.yml would be fine):
doctrine:
dbal:
default_connection: pressbox # change it as you wish
connections:
pressbox:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: pressbox
user: pressbox_usr
password: pressbox_pwd
charset: UTF8
fnt:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: fnt
user: fnt_usr
password: fnt_pwd
charset: UTF8
Then declare the entity managers:
doctrine:
orm:
default_entity_manager: pressbox
entity_managers:
pressbox:
connection: web
fnt:
connection: fnt
Now, in a controller, you can tell Doctrine which entity manager to use by passing its name to getEntityManager():
$fntEm = $this->getDoctrine()->getEntityManager('fnt');
Assuming the entity manager for the fnt table is called that same name.
i think cross database relations are pretty complicated or you have to code by hand through some plugin.

I use doctrine ORM in a Symfony 2.8 project.
My project contains several Bundles. For one Bundle, which generates Reports I want to use the db server with the slave replication as not to stress the master db server.
How to set this up?
What I tried so far:
In the config.yml
Doctrine Configuration
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
slave:
driver: pdo_mysql
host: '%database_host_slave%'
port: '%database_port_slave%'
dbname: '%database_name_slave%'
user: '%database_user_slave%'
password: '%database_password_slave%'
charset: UTF8
Here I created my second db connection with the values stored in my parameters.yml.
I seem to get the orm configuration I tried to setup in the same file not correctly.
Let my first explain what I need:
I have a "ReportingBundle" which runs a console command. The entity manager is only needed to provide the proper authorization to the needed db server. The queries itself are oure SQL and I don't use the entities.
my service.yml for this bundle:
services:
myproject.reporting.service.csv_report_attachment:
class: Myproject\ReportingBundle\Service\DefaultCsvReportAttachmentService
arguments: ['#doctrine.orm.slave_entity_manager', '#logger', '#myproject.reporting.service.php_template_engine', 'reportingHtmlMailTemplate.php']
Now my non functioning orm setup in the config.yml:
ORM configuration
orm:
auto_generate_proxy_classes: '%kernel.debug%'
# naming_strategy: doctrine.orm.naming_strategy.underscore
default_entity_manager: default
entity_managers:
slave:
connection: slave
mappings:
MyprojectReportingBundle: ~
default:
connection: default
auto_mapping : true
metadata_cache_driver: redis
query_cache_driver: redis
result_cache_driver: redis
This results in
[Doctrine\ORM\ORMException]
Unknown Entity namespace alias 'MyprojectReportingBundle'.
I tried to follow the documentation here:
http://symfony.com/doc/current/reference/configuration/doctrine.html#custom-mapping-entities-in-a-bundle
Question:
What is the correct syntax, so that my query is run on the slave server instead of the default server?
I believe you have everything configured correctly. However, you need to make sure the Entity classes are defined in the Bundle namespace. So for example you'd want to have all the entities defined within Myproject\ReportingBundle\Entity in your example.
I'm trying to set a different entity listener resolver because I want to use a couple of services among a few lifecycle callbacks. I googled out some answers that say it should be set in config the way similar to this one:
doctrine:
dbal:
driver: "%database_driver%"
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
charset: UTF8
orm:
auto_generate_proxy_classes: "%kernel.debug%"
auto_mapping: true
entity_listener_resolver: {HERE!}
However, when I do it this way, I get the following error:
Unrecognized options "entity_listener_resolver" under "doctrine.orm.entity_
managers.default"
Moreover, when I look at the configuration reference, I don't see such option anywhere or an option to set it: http://symfony.com/doc/current/reference/configuration/doctrine.html
So how do I change the entity listener resolver?
I'm using the newest Sf 2.5 version.
I'm running into the same issue, when using "doctrine/doctrine-bundle": "~1.2".
You have two options.
1) Use doctrine/doctrine-bundle 1.3 Beta, where the key entity_listener_resolver exists.
2) Or use the following gist to get it working without using the key: https://gist.github.com/vadim2404/9538227
More infos: http://egeloen.fr/2013/12/01/symfony2-doctrine2-entity-listener-as-serice/
Thx to the guy from the irc channel.
You can use it like this only in the services.yml for a specific bundle:
orm:
entity_listener_resolver: {your_entity_listener_resolver}
But in the config.yml file you need to set the entity listener resolver for a specific entity manager for example the default one:
orm:
entity_managers:
default:
entity_listener_resolver: {your_entity_listener_resolver}
The Symfony2 Cookbook provides information on how to create entities from existing schemas, but I haven't been able to find a way to import from another database called 'legacy' (see config.yml below) that isn't the default.
Running the following command creates YAML files only from the default database
$ php app/console doctrine:mapping:convert yml ./src/Soapbox/DashboardBundle/Resources/config/doctrine/metadata/orm --from-database --force
If I don't provide any arguments, I receive suggestions, but not sure which ones are applicable.
doctrine:mapping:convert [--filter="..."] [--force] [--from-database] [--extend[="..."]] [--num-spaces[="..."]] [--namespace[="..."]] [--em[="..."]] to-type dest-path
app/config/config.yml
# Doctrine Configuration
doctrine:
dbal:
default_connection: default
connections:
default:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
legacy:
driver: pdo_mysql
host: my.host
port: null
dbname: magazines
user: soapbox
password: XXXXX
charset: UTF8
If I'm thinking clearly which I might not be, you have two EntityManagers, default and legacy.
As such you can use the flag --em "legacy" to get it to import from that specific database.
I'm building a application using Symfony2 + Doctrine2. My application needs to store geospatial data, so I wrote the proper doctrine extensions. All is working pretty good and the app have been running in a production enviroment for a long time.
Now I have to add some new features and I need to update the database without deleting all the data. I thougth about using the DoctrineMigrationBundle but when I run:
$ php app/console doctrine:migrations:status
I got this error:
[Doctrine\DBAL\DBALException]
Unknown database type point requested,
Doctrine\DBAL\Platforms\MySqlPlatform may not
support it.
This is the relevant section of my config.yml:
# Doctrine Configuration
doctrine:
dbal:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
types:
point: App\EngineBundle\DoctrineExtensions\PointType
The custom type 'point' has been mapped, so what am I doing wrong?
I answer my own question, it seems the problem is DoctrineMigrations also needs a mapping for the custom type. So the config.yml should look like this:
# Doctrine Configuration
doctrine:
dbal:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
types:
point: App\EngineBundle\DoctrineExtensions\PointType
mapping_types:
point: point
I have two connections in config. And one of my bundles will use them together, but how i can specify which is used by entity class in that class?
Thanks for answering!
I'm not sure if one of your bundle will use one connection and another bundle will use the other one. Because you talking about class in your question:
... but how i can specify which is used by entity class in that class?
I will assume that one of your bundle which has entities will use a specific connection to map those entities to your database. To do this, you should provide the connection key in your configuration, something like this:
doctrine:
default_connection: default
connections:
default:
driver: "%database_driver%"
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
charset: UTF8
other:
driver: "%database_driver%"
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
charset: UTF8
orm:
auto_generate_proxy_classes: "%kernel.debug%"
default_entity_manager: default # The default entity manager if you specify more than one
entity_managers:
default:
# The name of a DBAL connection (the one marked as default is used if not set)
connection: other
mappings: # Required
AcmeHelloBundle: ~
# You can specify more bundle here
Moreover, I think it is even possible to specify specific classes as a list below the node AcmeHelloBundle. You will need to investigate this further to see if it possible.
You can check the doctrine configuration reference here for more configuration options for doctrine.
Hope this helps and that was what you were looking for.

Matt
