Symfony2 Doctrine 无法识别的字段：

Question

我创建了一个实体来存储我通过 api

提取的一些数据

当我尝试使用 findByOne 查看该条目是否已存在时，我收到一条错误消息，指出该字段未被识别。

我做了一个php app/console doctrine:schema:update --force 我可以在我的 mySQL 管理器中看到 table 具有正确的字段名 'StadiumID' 那么为什么当我这样做时教义找不到它 findByOne(); 我的实体 Class:

我用来添加数据（如果不存在）和更新它（如果存在）的代码：

<?php

namespace FantasyPro\DataBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use FantasyPro\DataBundle\Entity\Stadium;

class DefaultController extends Controller
{
    public function indexAction($name)
    {
        return $this->render('DataBundle:Default:index.html.twig', array('name' => $name));
    }

    public function updateStadiumAction(){
        //get list of stadiums
        $client = $this->container->get('fantasyapi');
        $stadiumData = $client->Stadiums();
        //var_dump($stadiumData);
        //get the entity manager
        $em = $this->getDoctrine()->getManager();
        $repo = $em->getRepository('DataBundle:Stadium');
        $log = $stadiumData;

        foreach($stadiumData as $stadium){
            // Get the current stadium in the list
            $criteria = array("StadiumID" =>$stadium['StadiumID']);
           var_dump($criteria);
            $storedStadium = $repo->FindOneBy($criteria);

            if (!$storedStadium) {
               /* throw $this->createNotFoundException(
                    'No product found for id '.$stadium['StadiumID']
                );*/
                //no stadium exists with the StadiumID passed
                //create a new entry
                $entry = new Stadium();
                $entry->setStadiumID($stadium['StadiumID']);
                $entry->setName($stadium['Name']);
                $entry->setCity($stadium['City']);
                $entry->setState($stadium['State']);
                $entry->setCountry($stadium['Country']);
                $entry->setCapacity($stadium['Capacity']);
                $entry->setPlayingSurface($stadium['PlayingSurface']);
                $em->persist($entry);
                $log .= 'Added New Stadium: '.$stadium['StadiumID'].' : '.$stadium['Name'].'<br>';
            }else{
                $storedStadium->setStadiumID($stadium['StadiumID']);
                $storedStadium->setName($stadium['Name']);
                $storedStadium->setCity($stadium['City']);
                $storedStadium->setState($stadium['State']);
                $storedStadium->setCountry($stadium['Country']);
                $storedStadium->setCapacity($stadium['Capacity']);
                $storedStadium->setPlayingSurface($stadium['PlayingSurface']);
                $em->persist($storedStadium);
                $log .= 'Updated Stadium: '.$stadium['StadiumID'].' : '.$stadium['Name'].'<br>';
            }
        }
        //$em->flush();
        return $this->render('DataBundle:Default:index.html.twig', array('log' => $log));
    }
}

Answer 1

属性名字实际上是：

private $stadiumID;

所以你应该这样做：

$repo->findOneBy(array('stadiumID' => $value));

所以更改此行：

$criteria = array("StadiumID" =>$stadium['StadiumID']);

对此：

$criteria = array("stadiumID" =>$stadium['StadiumID']);

Doctrine 的主要作用是将你的应用层（实体）连接到数据库层（表）。因此，学说试图将来自应用层的请求转换为数据库。即使您在数据库中将字段命名为 "StadiumID" 或 "table_name_snake_case"，当您调用 findOneBy(array($property => $value)) 时，学说也期望 $property 引用属性名称，并且它会将其翻译成 SQL 之类的 'SELECT FROM .... where StadiumID = :value'

Answer 2

对于仍有问题的其他人，
确保在调用函数 findOneBy(...)
时输入符号 '=>' 而不是 ',' 所以而不是：

findOneBy(["code" , "Code-Example"]);

这样做：

findOneBy(["code" => "Code-Example"]);

Answer 3

此外，请确保指定了学说命名策略：

doctrine:
    orm:
        naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware

这是学说的默认命名策略。这样学说就知道如何将实体属性名称映射到列名称。请注意，命名策略配置可能在不同级别的学说配置中。例如，在另一个 repo 中，它是这样配置的：

doctrine:
    orm:
        default_entity_manager: shopping
        entity_managers:
            shopping:
                naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
