Ansible escaping problem

gistfile1.txt

This works when I run it manualy from the shell:

 /bin/echo "from django.contrib.auth.models import User; User.objects.create_superuser('admin', '[email protected]', 'pass')" | /usr/bin/graphite-manage shell
 
 This is what I tried to do in Ansible:
 
   - name: test
    command: >
     /bin/echo "from django.contrib.auth.models import User; User.objects.create_superuser('{{graphite_admin_username}}', '{{graphite_admin_email}}', '{{graphite_admin_password}}')" | /usr/bin/graphite-manage shell

And this is the output from Ansible:

    changed: [graphite] => {"changed": true, "cmd": ["/bin/echo", "from django.contrib.auth.models import User; User.objects.create_superuser('admin', '[email protected]', 'password')", "|", "/usr/bin/graphite-manage", "shell"], "delta": "0:00:00.005750", "end": "2015-11-20 06:51:06.479436", "rc": 0, "start": "2015-11-20 06:51:06.473686", "stderr": "", "stdout": "from django.contrib.auth.models import User; User.objects.create_superuser('admin', '[email protected]', 'password') | /usr/bin/graphite-manage shell"}
    
But it does not achieve a desired result.
