symfony1 - Symfony and Doctrine: sluggable behaviour: field called "slug" is not created -

I have this model:

  User: Acts: sluggable: Unique: Correct field: [Nombre_apellidos] canUpdate: true inheritance: extends: sfGuardUser Type: Simple Column: Username: Type: String (128) notnull: false unique: true nombre_apellidos: string (60) sexo: boolean fecha_nac: date provincia: string 60) localidad: string (255) #email_address: string (255) photography: string (255) avatar: string (255) relationships: user: local: user1_id exotic: user2_id refClass: amigoUsurario alike: true  

I am Expectation was created that was called "Slug" field "construction principle: Since the creation --all", but did not.

Why is not an area created "slug"?

Symfony 1.3

I got to the same problem and set a unique set of lies Fixed by If unique is not very important to you, then it will solve your problem.
