php - 向 Symfony BaseModel 添加属性

问题描述

我有以下 symfony 模型，我需要向name现有模型添加一个属性（见下文），然后相应地更新数据库。实现此目的的正确方法是什么？我很感激任何建议。

我尝试运行 php bin/console dictionary:database:drop 然后 php bin/console dictionary:database:create，希望它会进行必要的映射，但没有任何成功，我收到以下错误：You have requested a non-existent service "doctrine".

这似乎过于复杂，我相信有一种更简单的方法可以实现这一点。我很感激任何建议。

解决方案

看起来 Doctrine 没有在您的应用程序中完全配置。这可能也是无法找到该服务的原因。

请确保在您的 AppKernel.php 中注册了 DoctrineBundle（搜索new Doctrine\Bundle\DoctrineBundle\DoctrineBundle()）。

接下来，您将需要学说配置。如果需要参考配置，可以检查存储库：

# Doctrine Configuration
doctrine:
    dbal:
        driver:   pdo_mysql
        host:     "%database_host%"
        port:     "%database_port%"
        dbname:   "%database_name%"
        user:     "%database_user%"
        password: "%database_password%"
        charset:  UTF8
        # if using pdo_sqlite as your database driver:
        #   1. add the path in parameters.yml
        #     e.g. database_path: "%kernel.root_dir%/data/data.db3"
        #   2. Uncomment database_path in parameters.yml.dist
        #   3. Uncomment next line:
        #     path:     "%database_path%"

    orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true

还要确保您的 parameters.yml 和 parameters.yml.dist 包含配置所需的值。同样，您可以从官方存储库中获取文件作为参考。
