Symfony2 - “警告：class_parents（）：Class Ambience不存在且无法加载”

Question

I am trying to create an entity using yml and I am getting the following error:

[ErrorException]

  Warning: class_parents(): Class Ambience does not exist and could not be loaded in C:\wamp\www\demo\vendor\gedmo-doctrine-extensions\lib\Gedmo\Mapping\ExtensionMetadataFactory.php line 80

I have created a file named Entities.UserTestDelete.dcm.yml in FooBundle/Resources/config/doctrine/metadata/orm

Contents of file:

Entities\UserTestDelete:
  type: entity
  table: users
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    name:
      type: string
      length: 50

Then I executed the following command:

php app/console doctrine:mapping:import "DemoFooBundle" yml

And then I got the error. Any idea why would that be a problem?

Update
Your first mistake is that you created the yml file. As explained in the cookbook, the doctrine:mapping:import command actually generates the file. Ditch yours, run the command, and let doctrine generate the file itself.
What you do afterwards, is generate the actual entity classes:

php app/console doctrine:mapping:convert annotation ./src
php app/console doctrine:generate:entities DemoFooBundle

If the tables themselves don't exist yet, then you can use these last 2 commands to generate the entities, and then run

php app/console doctrine:schema:update --force

To have doctrine create the tables for you.

A quick look in the cookbook tells me that the bundle name should not be quoted, and that you might want to pass the --force flag to the doctrine:mapping:import command.
It's in the reverse-engineering bit

php app/console doctrine:mapping:import --force DemoFooBundle yml

That's the example Symfony2 cookbook gives, only changed to take yml, instead of xml format.

The error message could also be related to the table name:

table: users

Where the entity is called

class Users
{}
