Doctrine table class inheritance when one subclass has no extra attributes

Question

I\'m having a problem with my mapping. I can\'t get it to work. I have an abstract base class like so:

/**
 * @Entity
 * @Table(name=\"actions\")
 * @Inheritance         


        

Answer 1

Bit of a late response but it may be useful for others asking this question.

Make the class 'AbstractAction' concrete and add a mapping for it in the discriminator map (You probably want to rename it at this point)

 * @DiscriminatorMap({"ABSTRACT" = "AbstractAction", "FOO" = "FooAction", "BAR" = "BarAction", ...})
 */
class AbstractAction
{

You should then use that table for rows which need no additional columns
