This utility command publishes messages to a specified queue. You can publish a single message by giving the queue name |
|
28
|
|
|
and the payload: |
|

|
|
|
|
|
30
|
|
|
<comment>php app/console %command.name% mail.send "[email protected]" "This is a test subject" "This is the body"</comment> |
|
31
|
|
|
|
|
32
|
|
|
Or you can perform a Doctrine query where the entiry result set is published: |
|
33
|
|
|
|
|
34
|
|
|
<comment>php app/console %command.name% article.publish -d "SELECT a FROM AcmeBlogBundle:Article a WHERE a.published = 0"</comment> |
