当我尝试为实体创建原则 crud 时，我收到“未知实体 namespace 别名”异常。

我有以下项目结构

使用 src\Project\Entity 目录中的实体的一系列 bundle (在 Bundles 目录中)。

如你所见，我的实体命名空间是

    namespace Project\Entity;

我觉得这可能与 auto_mapping 有关，但我已经玩了 4-5 个小时，但一无所获。

有什么建议吗？

最佳答案

解决方法:

创建一个扩展基本原则 crud 命令的命令

扩展\Sensio\Bundle\GeneratorBundle\Command\GenerateDoctrineCrudCommand

修改

 $entityClass = $this->getContainer()->get('doctrine')->getAliasNamespace('Project').'\\'.$entity;

实体的命名空间。默认情况下，它假定实体位于您希望创建 CRUD 的 Bundle 中。

通过设置

$this->setName('project:generate:crud');

在 Configre() 函数中，您可以从命令行调用该函数

例子:

<?php

namespace Project\Bundle\UtilityBundle\Command;

use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Question\ConfirmationQuestion;
use Sensio\Bundle\GeneratorBundle\Command\Validators;

class GenerateDoctrineCrudCommand extends \Sensio\Bundle\GeneratorBundle\Command\GenerateDoctrineCrudCommand
{
protected function configure()
{
    parent::configure();

    $this->setName('project:generate:crud');
    $this->setDescription('CRUD generator that supports entities outside a bundle');
}

protected function execute(InputInterface $input, OutputInterface $output)
{
    $questionHelper = $this->getQuestionHelper();

    if ($input->isInteractive()) {
        $question = new ConfirmationQuestion($questionHelper->getQuestion('Do you confirm generation', 'yes', '?'), true);
        if (!$questionHelper->ask($input, $output, $question)) {
            $output->writeln('<error>Command aborted</error>');

            return 1;
        }
    }

    // Note: this expects an argument like InterpracCorporateFrontendBundle:Notification
    list($bundle, $entity) = explode(':', $input->getOption('entity'));

    $format = Validators::validateFormat($input->getOption('format'));
    $prefix = $this->getRoutePrefix($input, $entity);
    $withWrite = $input->getOption('with-write');
    $forceOverwrite = $input->getOption('overwrite');

    $questionHelper->writeSection($output, 'CRUD generation');

    $entityClass = $this->getContainer()->get('doctrine')->getAliasNamespace('Project').'\\'.$entity;
    $metadata    = $this->getEntityMetadata($entityClass);
    $bundle      = $this->getContainer()->get('kernel')->getBundle($bundle);

    $generator = $this->getGenerator($bundle);
    $generator->generate($bundle, $entity, $metadata[0], $format, $prefix, $withWrite, $forceOverwrite);

    $output->writeln('Generating the CRUD code: <info>OK</info>');

    $errors = array();
    $runner = $questionHelper->getRunner($output, $errors);

    // form
    if ($withWrite) {
        $output->write('Generating the Form code: ');
        if ($this->generateForm($bundle, $entity, $metadata)) {
            $output->writeln('<info>OK</info>');
        } else {
            $output->writeln('<warning>Already exists, skipping</warning>');
        }
    }

    // routing
    if ('annotation' != $format) {
        $runner($this->updateRouting($questionHelper, $input, $output, $bundle, $format, $entity, $prefix));
    }

    $questionHelper->writeGeneratorSummary($output, $errors);
}
}
