How to properly update a managed entity using data from a non-managed entity?
Controlling what Doctrine persists Update existing entities only if required.

Is it good practice to have a getter for every property in a class representing a row, or should I investigate another approach?
I think this is more of a design preference, but there are many advantages of using getters/setters. Encapsulation and hiding internals are typically good practice. Interoperability is another reason why using getters and setters is a good idea (ie. mocking becomes much easier). Whether you want to do this for...
JPA/Hibernate Query Slow with too many queries
