Doctrine: create fixtures for a certain table

Is it possible to create a fixtures yml file for a certain model from the data already stored in the database (e.g开发者_高级运维. like dump-data CLI but with specifying which data)?

---

When loading fixtures, you explicitly declare the models in the fixture file so this is the only way to do it, as far as I know.

If you're referring to loading fixtures into a database with existing data, loading fixtures for a specific model should not affect data in other tables, as long as you don't re-build the models. I haven't tested this though, so please do try it out in a safe environment first.

Another thing to bear in mind is that the data you upload as fixtures need to respect any foreign-key constraints you may have in your database.
