使用YAML的Symfony2 Doctrine索引

Question

Because documentation on YAML in Doctrine isn't really informative, I was trying to create indexes for few (already existing) tables from exaple codes. I put some additional lines to my *.orm.yml files, but after calling app/console doctrine:generate:entities and app/console doctrine:schema:update --force I get a message that my database is already in sync.That's kind of problematic - I'm not an expert in Symfony nor database management at all, but as far as I know indexing your tables is kind of crucial when I use queries a lot, mostly searching by values from one column of a table, ain't I right? So please, help me to create indexes via Symfony/Doctrine using YAML, I have no idea what more I can do.

Here's one of my .orm.yml files:

Sc0\LoginBundle\Entity\LoginDictionary:
  type: entity
  table: login_dictionary
  indexes:
    login_dictionary_index:
      columns: [ name ]

  id:
    name:
      type: string
      length: 30

  fields:
    polish:
      type: string
      length: 150
      nullable: false

If it's important I'm using PostgreSQL for database management. Maybe I should just create standard indexes using normal postgres queries? Will Symfony 'see' those indexes created manually?

Since name is a primary key there is already an index for this column. You can check with PHPMyAdmin. That's why you have the message that the database is already synced: an index is already present.
