Question

我有一个使用Symfony 2中的Gedmo Tree Doctrine扩展分层的实体.Categics实体的代码是：

<?php

    protected $slug;



    /**

    /**

        }

        return $this;
    }

    public function addChild(Category $child = null)
    {
        if (!$this->children->contains($child)) {
            $this->children->add($child);
            $child->setParent($this);
        }

        return $this;
    }

    /**

    }

    /**

    public function setSlug($slug)
    {
        $this->slug = $slug;

        return $this;
    }

    /**

    /** Magic Methods */

    /**

     *
     * @return string
     */
    public function __toString()
    {
        return $this->getTitle();
    }
}

鉴于标题为Bands的类别和标题为Rock的子类别，后一类别在创建时具有bands/rock标题。这可以按预期工作。

当我将slug字段添加到表单时，当我编辑实体时，我最初将bands/rock添加到表单字段中。如果我将其更改为bands/rock-and-roll并提交表单，那么slug会更新为bands/bands-rock-and-roll而不是bands/rock-and-roll，如我所料。

如果我编辑类别并将slug字段设置为rock-and-roll，则提交表单，slug会更新为bands/rock-and-roll。我希望更新后的slug为rock-and-roll。

我需要做些什么才能解决此问题？我基本上想要使用处理程序自动生成slug，如果它没有提供，但是如果我提供它就要设置为我提供的。

查看Gedmo Tree Doctrine extension的文档及其相关代码，这不是一个错误的行为，因为slug是相应的“ TreeSlugHandler ”方法= parentFieldName / field -You-Have-Inserted （每次编辑slug时都会发生这种情况）。

如果您需要同一时刻的特定类别和另一个类别树的slug，您可以使用简单注释添加另一个属性（例如：cat_slug）：@Gedmo \ Slug（fields = {“fieldYouWantToSlug “}）。

请记住，每次（使用“TreeSlugHandler”方法）编辑slug（更改先例）时，每个子类别都将使用新的slug进行更新。

我希望我有所帮助

使用Gedmo TreeSlugHandler编辑Slug
