Symfony2 MongoDB多个连接错误

Question

I have an issue setting up MongoDB in Symfony2.

Specs:

"Symfony": "2.6.*"
"doctrine/mongodb-odm": "1.0.*@dev",
"doctrine/mongodb-odm-bundle": "3.0.*@dev"

I have 2 databases used in 2 different bundles, nxtlog and nxtsurvey, in MongoDB. The original issue I had was that the db name I added in options was not taken into account, which resulted in database 'default' to be used, which of course does not exist. I also do not want to add default_connection and default_manager, nor even default_database as both connections are used in not-core bundles.

==== Attempt #1 ====

Here is the original config I had:

doctrine_mongodb:
    connections:
        nxtlog:
            server: "%nxtlog_database_server%"
            options:
                username: "%nxtlog_database_username%"
                password: "%nxtlog_database_password%"
                db: "%nxtlog_database_name%"
        nxtsurvey:
            server: "%nxtsurvey_database_server%"
            options:
                username: "%nxtsurvey_database_username%"
                password: "%nxtsurvey_database_password%"
                db: "%nxtsurvey_database_name%"
    document_managers:
        nxtlog:
            mappings:
                NxtLogBundle: ~
        nxtsurvey:
            mappings:
                NxtVibeSurveyBundle: ~

In order to make it work, I added the name of the db in each Document annotations:

/**
 * @MongoDB\Document(db="nxtlog")
 */
class ErrorLogs

Which is a temporary solution, but since my plan is to reuse the bundles in my other projects, I do not want to have to go through all documents and set the name of the db.

==== Attempt #2 ====

My second attempt was to rigorously follow the documentation, and therefore I tried the following:

doctrine_mongodb:
    connections:
        nxtlog_conn:
            server: "%nxtlog_database_server%"
            options:
                username: "%nxtlog_database_username%"
                password: "%nxtlog_database_password%"
                connect: true
                db: "%nxtlog_database_name%"
        nxtsurvey_conn:
            server: "%nxtsurvey_database_server%"
            options:
                username: "%nxtsurvey_database_username%"
                password: "%nxtsurvey_database_password%"
                connect: true
                db: "%nxtsurvey_database_name%"
    document_managers:
        nxtlog_dm:
            connection: nxtlog_conn
            mappings:
                NxtLogBundle: ~
        nxtsurvey_dm:
            connection: nxtsurvey_conn
            mappings:
                NxtVibeSurveyBundle: ~

And get the following error:

ServiceNotFoundException in CheckExceptionOnInvalidReferenceBehaviorPass.php line 58:
The service "doctrine_mongodb.odm.nxtlog_conn_connection" has a dependency on a non-existent service "doctrine_mongodb.odm.nxtlog_conn_configuration".

So I figured out that I could not have different names for connections and data-managers. Which I did not believe, so I googled it, and someone had a similar issue, and the answer was to add the following under doctrine_mongodb:

default_commit_options: ~

But this solution did not work for me, and after more googling, I found out that jmikola, the guy who wrote the bundle (or parts of it), made a mistake, he said he fixed it, and that default_commit_options should not be a required configuration option. (ref. https://github.com/doctrine/DoctrineMongoDBBundle/issues/222 )

At this point I would need some help, because this is taking far too much time to solve.

Thanks

Answer 1

Quite some time ago I tried to setup multiple Doctrine connections, too, although I used Zend Framework (and the respective Doctrine modules) at the time. If I remember correctly, you have to setup all Doctrine services with the new namespace added (in your case nxtlog_conn ).

I checked the source of the ZF2 DoctrineMongoODMModule and it is still how I remembered it: if you want to have the connection, you need a Doctrine configuration service prefixed with the same namespace.

Judging from your error message, this also applies to the Symfony bundle, albeit I couldn't find the responsible location in the bundles source code.

The service "doctrine_mongodb.odm.nxtlog_conn_connection" has a dependency on a non-existent service "doctrine_mongodb.odm.nxtlog_conn_configuration" .

This basically tells you: I want a connection, but wait a second, I can't find the corresponding configuration!

Try to find how the configuration is set up for the orm_default connection and set up your configuration like wise. If you encounter another error of the same format, hunt the next required service name and then rinse and repeat.
