[FLOW3-general] Self referencing M:N Relation

[Cornel Widmer]

Sorry folks

I really try hard to get over the starting problems. Most of my problems are ORM related ... so this one either.

I need a self referencing Many-to-Many relation. In my model i have the model company, with the property customers and providers. Each  Company can have multiple Customers (Company-Model) and so every Company can have multiple Providers (Company-Model).

First try...

/**
 * @var \Doctrine\Common\Collections\ArrayCollection<\WS\Rico\Domain\Model\Company>
 * @ORM\ManyToMany(mappedBy="companyCustomers")
 * @ORM\Column(nullable=true)
 */
protected $companyProviders;

/**
 * @var \Doctrine\Common\Collections\ArrayCollection<\WS\Rico\Domain\Model\Company>
 * @ORM\ManyToMany(inversedBy="companyProviders")
 * @ORM\Column(nullable=true)
 */
protected $companyCustomers;


The first update with doctrine:update was successfull, but something is wrong. No associations are stored in the database. When I try to update the Database again I'm getting errors.

How to do that?

I also tried to adopt the example of doctrine ... but not with usable results.
