Doctrine Sluggable - 列 'slug' 不能为空

Question

我正在使用 Doctrine，通过 StofDoctrineExtensionsBundle 使用 DoctrineExtensions 使用 "Doctrine Extensions Sluggable" 行为自动生成 slugs。

侦听器似乎已正确注册。实体字段也被标记为 sluggable。

当尝试通过 Symfony 表单保留我的实体时，不会生成 slug。正在抛出数据库异常。

异常：

An exception occurred while executing 'INSERT INTO event (startDate, endDate, title, slug, description, image, followers, city, place) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)' with params ["2017-06-24 20:00:00", "2017-06-26 12:00:00", "Test event name for slug generation", null, "Test", null, null, "Somewhere", "Somewhere else"]:

Answer 1

正如异常告诉你的那样：

'slug' cannot be null

您需要修改 'Event.orm.xml' 中的属性定义，并使 slug 可以为 null，因为它默认为 nullable false。

所以你需要像那样改变你的定义:

        <field name="slug" type="string" column="slug" length="255" unique="true" nullable="false">
            <gedmo:slug unique="true" updatable="true" fields="title" separator="-" />
        </field>

这将解决您的异常。但是，真正的问题是 slug 属性上的唯一约束：第二次当你插入一个值为 'null' 的事件时，它会触发唯一约束，因为已经有一行带有 null slug . 所以你需要提供 slug 或删除唯一约束。

Answer 2

当我实现 StofDoctrineExtensionsBundle 时，我第一次执行了一个将所有 slug 值设置为 null 的函数。（当 slug 设置为 null 时，侦听器调用 slug 值被填充。

希望对您有所帮助。

Answer 3

我看到的唯一区别是您的 xml 命名空间声明。您在使用版本 2.x 时为版本 3.x 引用了 url。官方文档使用这个模式

http://gediminasm.org/schemas/orm/doctrine-extensions-mappin‌g

确保相应地更新您的 xml 映射：

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd"
                  xmlns:gedmo="http://gediminasm.org/schemas/orm/doctrine-extensions-mappin‌g">
    <entity repository-class="AppBundle\Repository\EventRepository" name="AppBundle\Entity\Event">
        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>
        <field name="startDate" type="datetime" column="startDate"/>
        <field name="endDate" type="datetime" column="endDate"/>
        <field name="title" type="string" column="title" length="255"/>
        <field name="slug" type="string" column="slug" length="255" unique="true">
            <gedmo:slug unique="true" updatable="true" fields="title" separator="-" />
        </field>
        <field name="description" type="text" column="description" nullable="true"/>
        <field name="image" type="string" column="image" length="255" nullable="true"/>
