视图实体上的“没有为实体指定标识符/主键”错误

Question

Symfony 6

No identifier/primary key specified for Entity "App\Entity\ContactVw". Every Entity must have an identifier/primary key.

I know how to fix that error when using a simple table.

But how can I fix that error when I am using a view. Views don't have primary keys. Where in the class definition do I have to tell doctrine what column to use as primary?

This is my class

<?php

namespace App\Entity;

use Doctrine\DBAL\Types\Types;
use Doctrine\ORM\Mapping as ORM;

/**
 * ContactVw
 *
 * @ORM\Table(name="contact_vw", indexes={@ORM\Index(name="city", columns={"city"}), @ORM\Index(name="customer", columns={"customer"}), @ORM\Index(name="name", columns={"name"}), @ORM\Index(name="country_sold_to", columns={"country_sold_to"})})
 * @ORM\Entity
 */

{

        #[Id, Column]
        private string $contactId,
    ) {

Answer 1

You did not set an identifier on any attribute, which you can do using:

#[ORM\Id] // Php Attribute

/**
* @ORM\Id // Annotation
**/
enter code here

In your code:

#[Id, Column] // seems wrong

You are mixing annotation and Php Attribute to define how your entity work: dont do that . Personnally, i recommend php attribute over annotation if you can use it.
