Doctrine one-to-many relation - "No identifier/primary key specified"


I'd rather give you working example of OneToMany from one of my projects, so you can see the difference and format code in proper way. If it does not work, then try to get a new Symfony dist and start over.

<?php
// SomeBundle/Entity/Shop/Product.php
namespace SomeBundleEntityShop;

use DoctrineORMMapping as ORM;

/**
 * @ORMEntity
 * @ORMTable(name="shop_products")
 */
class Product
{
    /**
     * @ORMId
     * @ORMGeneratedValue
     * @ORMColumn(type="bigint")
     */
    protected $id;

    /**
     * @ORMOneToMany(targetEntity="ProductItem",
mappedBy="product")
     */
    protected $productItem;
}

Related entity:

<?php
// SomeBundle/Entity/Shop/ProductItem.php
namespace SomeBundleEntityShop;

use DoctrineORMMapping as ORM;

/**
 * @ORMEntity
 * @ORMTable(name="shop_products_items")
 */
class ProductItem
{
    /**
     * @ORMId
     * @ORMGeneratedValue
     * @ORMColumn(type="bigint")
     */
    protected $id;

    /**
     * @ORMManyToOne(targetEntity="Product",
inversedBy="productItem")
     * @ORMJoinColumn(name="product_id",
referencedColumnName="id")
     */
    protected $product;
}

For reasons why your code does not work could be many (namespaces, folder structure, column names, etc.). This example works and tested. Give it a try : )

Cypher - Return nodes with their relation with a count contraint on the relation
Untested, but you should be able to unwind your rels collection and pull out the start and end nodes. Something like: MATCH (doc:document)-[contain]-(sentence)-[with]-(ng1:word)-[rel:relations]-(ng2:word) WITH doc, count(rel) as nbRels, collect(rel) as rels WHERE nbRels > 10 WITH doc, UNWIND(rels) as rel, RETURN doc, STARTNODE(rel), ENDNODE(rel) But you might just want to collect something d

What is the difference between PRIMARY KEY and CONSTRAINT PRIMARY KEY?
I think both primary key definitions are identical. See my sqlfiddle. and output from show create table Employes_1 und _2: Employees_1 | CREATE TABLE employees_1 ( E_Id int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (E_Id) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 Employees_2 | CREATE TABLE employees_2 ( E_Id int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (E_Id) ) ENGINE=InnoDB DEFAUL

Can Doctrine Join itself
To answer the specifically stated question, you can easily join any entity to itself (even if it does not have a self-referential association), simply by joining to the entity shortcut name (instead of the associated field name like normal). $viewVersionRepo = $em->getRepository('GutensiteCmsBundle:ViewViewVersion'); $queryBuilder = $viewVersionRepo->createQueryBuilder('e') //
