Querying the Database
... Now that we've saved some stuff to the database, how can we read or query for it?
Once again, at least for simple stuff, Doctrine doesn't want you to worry about
querying. Instead, we just ask Doctrine for the objects ...
Persisting to the Database
... Doctrine will
handle the insert queries for us.
To help do this in the simplest way possible, let's make a fake "new Vinyl Mix"

... ... simply to count them! That's total overkill!
As soon as we access this answers property, Doctrine queries for all the data

... save or persist that object. Usually, this means that we're saving an entity

The QueryBuilder
Doctrine speaks DQL, even though it converts it eventually to SQL. But actually,
I don't write a lot of DQL. Instead, I use the QueryBuilder: an object
that helps you build a DQL string. The QueryBuilder is one of my ...
The Mysterious User Provider
... User from the session and making sure that it's
up to date. In Doctrine, we'll want our's to re-query for a fresh User object to
make sure all the data is still up-to-date.
