這是DoctrineCrudGenerator的正常行爲，由於發電機僅使用Doctrine\ORM\Mapping\ClassMetadataInfo::$fieldMappings陣列生成表，但ParentAlbum，多對一協會位於Doctrine\ORM\Mapping\ClassMetadataInfo::$associationMappings陣列中。所以它永遠不會被認爲是殘酷的一代。
爲了展示一個可能的解決方案，我用的symfony-演示應用程序的註釋實體：

}
有喜歡的ID，內容，AUTHOREMAIL和publishedAt和一個多對一關聯早報「正常」列實體。對於這個實體產生以下元數據：

你可以看到，正常的域位於fieldMappings陣列中，而該協會所居住的associationMappings陣列英寸 運行的註釋實體渣滓發生器產生的表僅適用於「正常」列不交的關聯關係：
<thead>
<tr>
<th>Id</th>
<th>Content</th>
<th>Authoremail</th>
<th>Publishedat</th>
<th>Actions</th>
</tr>
</thead>
現在，要改變這種行爲，你只需要「合併」中的associationMappings陣列現場監視數組在crud世代。 你可以在Sensio\Bundle\GeneratorBundle\Generator\DoctrineCrudGenerator中做到這一點。對於生產，您必須覆蓋 Sensio\Bundle\GeneratorBundle\Generator\DoctrineCrudGenerator和Sensio\Bundle\GeneratorBundle\Command\GenerateDoctrineCrudCommand 並在您自己的類中進行更改。但正如概念證明我會做快速，真正骯髒的黑客，一個直接添加 以下更改DoctrineCrudGenerator：
/**
* Generates a CRUD controller.
*
* @author Fabien Potencier <[email protected]>
*/
class DoctrineCrudGenerator extends Generator
{
// ...
/**
* Generates the index.html.twig template in the final bundle.
*
* @param string $dir The path to the folder that hosts templates in the bundle
*/
protected function generateIndexView($dir)
{
$this->renderFile(
'crud/views/index.html.twig.twig',
$dir . '/index.html.twig',
array(
'bundle' => $this->bundle->getName(),
'entity' => $this->entity,
'identifier' => $this->metadata->identifier[0],
// Use the function instead of the "raw" fieldMappings array
// 'fields' => $this->metadata->fieldMappings,
'fields' => $this->processFieldMappings(),
'actions' => $this->actions,
'record_actions' => $this->getRecordActions(),
'route_prefix' => $this->routePrefix,
'route_name_prefix' => $this->routeNamePrefix,
)
);
}
// ...
/**
* Add the associations to the array
*
* @return array
*/
protected function processFieldMappings()
{
/** @var \Doctrine\ORM\Mapping\ClassMetadata $metadata */
$metadata = $this->metadata;
$fields = $metadata->fieldMappings;
$associationMappings = $metadata->associationMappings;
foreach ($associationMappings as $k => $a) {
// Add the field only if it is a ToOne association and if the targetEntity implements the __toString method
if ($a['type'] & ClassMetadataInfo::TO_ONE && method_exists($a['targetEntity'], '__toString')) {
$fields[$k] = array(
"fieldName" => $a["fieldName"],
"type" => "text",
"scale" => 0,
"length" => null,
"unique" => false,
"nullable" => false,
"precision" => 0,
"columnName" => $k
);
}
}
return $fields;
}
}
更改後，如果您添加了__toString向早報實體，發電機產生以下代碼：
<table class="records_list">
<thead>
<tr>
<th>Id</th>
<th>Content</th>
<th>Authoremail</th>
<th>Publishedat</th>
<th>Post</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
{% for entity in entities %}
<tr>
<td><a href="{{ path('comment_show', { 'id': entity.id }) }}">{{ entity.id }}</a></td>
<td>{{ entity.content }}</td>
<td>{{ entity.authorEmail }}</td>
<td>{% if entity.publishedAt %}{{ entity.publishedAt|date('Y-m-d H:i:s') }}{% endif %}</td>
<td>{{ entity.post }}</td>
<td>
<ul>
<li>
<a href="{{ path('comment_show', { 'id': entity.id }) }}">show</a>
</li>
<li>
<a href="{{ path('comment_edit', { 'id': entity.id }) }}">edit</a>
</li>
</ul>
</td>
</tr>
{% endfor %}
</tbody>
</table>
您可以看到，現在可以識別該後期關聯。如果你想開始寫你自己的發電機，你可以用它作爲入口點。但您必須調查，如何處理ToMany關聯以及如何處理 表單等中的關聯。
它必須包含3個字段：name，sort，parent。父字段未生成。 –
