Roles in Sonata Admin

问题

Good day. I can not understand how in sonata admin bundle to add roles to users. Namely, it is necessary that the user with a specific role seen in adminpanel only one entity and only worked with her. For now, there is only one role - it ROLE_SONATA_ADMIN, which gives access to the whole adminpanel. On official site found just such an example :

security:
    ...
    role_hierarchy:
        # for convenience, I decided to gather Sonata roles here
        ROLE_SONATA_FOO_READER:
            - ROLE_SONATA_ADMIN_DEMO_FOO_LIST
            - ROLE_SONATA_ADMIN_DEMO_FOO_VIEW
        ROLE_SONATA_FOO_EDITOR:
            - ROLE_SONATA_ADMIN_DEMO_FOO_CREATE
            - ROLE_SONATA_ADMIN_DEMO_FOO_EDIT
        ROLE_SONATA_FOO_ADMIN:
            - ROLE_SONATA_ADMIN_DEMO_FOO_DELETE
            - ROLE_SONATA_ADMIN_DEMO_FOO_EXPORT
        # those are the roles I will use (less verbose)
        ROLE_STAFF:             [ROLE_USER, ROLE_SONATA_FOO_READER]
        ROLE_ADMIN:             [ROLE_STAFF, ROLE_SONATA_FOO_EDITOR, ROLE_SONATA_FOO_ADMIN]
        ROLE_SUPER_ADMIN:       [ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

But I can not understand that instead embed DEMO, and that instead of FOO. Tried a lot of options but nothing is worked.

Thanks in advance and sorry for my bad English.

The permissions are:

• LIST: view the list of objects
• VIEW: view the detail of one object
• CREATE: create a new object
• EDIT: update an existing object
• DELETE: delete an existing object
• EXPORT (for the native Sonata export links)
