Doctrine Schema Create for just one Bundle
When you create a new bundle, just use
app/console doctrine:schema:updateSince your schema exists already.
Sometimes using php app/console doctrine:schema:update --force doesn't resolve the problem, so you can simply comment other bundles from the AppKernel.php in $bundles and then use php app/console doctrine:schema:update --force again, it should work.
Don't forget to uncomment commented bundles.
If your bundles are mapped to different entity managers, you can (or must) use the argument "--em entity_manager_name" for the schema update command.
Example:
app/console doctrine:schema:update --em my_own_entity_manager_name
