[symfony-users] Doctrine ORM Inheritance

[DisTurBinG]

Hello All,

I'm new and having a problem with inheritance.

I have two things I want to solve

First:

Input: [b]console doctrine:generate:entities [/b]
Error: [b]No identifier/primary key specified for Entity 'Bundle
\RegisterBundle\Entity\Member'. Every Entity must have an identifier/
primary key.  [/b]

The Primary key is not being inherited for some reason.  How could I
use ORM to allow the parent to have a primary key?

NOTE: [b]I know that the orm works because if I put the ID into both
Member.php and AbstractMember.php, It works fine and creates the
tables.[/b]

Code:
// AbstractMember.php
[code]
/**
 * @orm:Entity
 * @orm:InheritanceType("SINGLE_TABLE")
 * @orm:DiscriminatorColumn(name="discr", type="string")
 * @orm:DiscriminatorMap({"member" = "AbstractMember", "cookon_member"
= "CookonMember"})
 * @orm:Table(name="member")
 *
 * Abstract member class
 *
 * @author Disturbing
 */
abstract class AbstractMember
{
    /**
     * @orm:id
     * @orm:Column(type="integer")
     * @orm:GeneratedValue(strategy="IDENTITY")
     */
    private $id;

        /**
     * @orm:email
     * @orm:Column(type="string", length="32")
     *
     * @validation:NotBlank(message="You must enter your email
address.")
     * @validation:Email(checkMX=true)
     * @validation:MaxLength(32)
    */
    private $email;

    /**
     * @orm:password
     * @orm:Column(type="string", length="32")
     *
     * @validation:NotBlank(message="You must enter a password.")
     * @validation:MinLength(6)
     * @validation:MaxLength(32)
    */
    private $password;

    public function getEmail()
    {
        return $this->email;
    }

    public function setEmail($email)
    {
        $this->email = $email;
    }

    public function getPassword()
    {
        return $this->email;
    }

    public function setPassword($password)
    {
        $this->password = $password;
    }
}
[/code]
Code:
// Member.php
[code]
<?php

namespace Bundle\RegisterBundle\Entity;

/**
 * @orm:Entity
 * @orm:inheritance(type="simple", extends="AbstractMember")
 *
 * Unique Member Class
 *
 * @author Disturbing
 *
 */
class Member extends AbstractMember
{
    /**
     * @orm:first_name
     * @orm:email
     * @orm:Column(type="string", length="16")
     *
     * @validation:NotBlank(message="You must enter a first name.")
     * @validation:MinLength(2)
     * @validation:MaxLength(16)
     * @validation:Regex(pattern="{^[A-Za-z]+$}", message="Last name
must only container letters.")
     */
    private $firstName;
    /**
     * @orm:last_name
     * @orm:Column(type="string", length="16")
     *
     * @validation:NotBlank(message="You must enter a last name.")
     * @validation:MinLength(2)
     * @validation:MaxLength(16)
     * @validation:Regex(pattern="{^[A-Za-z]+$}", message="Last name
must only container letters.")
     */
    private $lastName;

    /**
     * @orm:zip_code
     * @orm:Column(type="integer")
     *
     * @validation:NotBlank(message="You must enter your zip code.")
     * @validation:AssertType(type="numeric", message="You entered an
invalid zip code.")
     * @validation:MaxLength(5)
     */
    private $zipCode;

    public function getFirstName()
    {
       return $this->firstName;
    }

    public function setFirstName($firstName)
    {
        $this->firstName = $firstName;
    }

    public function getLastName()
    {
       return $this->lastName;
    }

    public function setLastName($lastName)
    {
        $this->lastName = $lastName;
    }

    public function getZipCode()
    {
       return $this->zipCode;
    }

    public function setZipCode($zipCode)
    {
        $this->zipCode = $zipCode;
    }
}
[/code]


Second Problem:

With Inheritance, why do I need @orm:DiscriminatorColumn(name="discr",
type="string").
I want to be inheriting with a SINGLE_TABLE and no references.  Maybe
the discriminator key needs to be unique id?  Please explain on this
if any.

I've looked all over google and can't find a solution, it seems just
basic:  * @orm:inheritance(type="simple", extends="AbstractMember")
with YML configuration works fine from what people say, but it isn't
here.

Best Regards, Thanks in Advance and Thanks for the wonderful
Framework.
