我不得不从旧数据库中引入数据，如下所示：
<?php
public function sync()
{
$persist_count = 0; // Keep track of home many properties are ready to be flushed
$flush_count = 20; // Persist and flush the properties in groups of...
$i = 0;
$CI =& get_instance();
$legacy_properties = null;
while ($legacy_properties !== false)
{
$legacy_properties = $this->doctrine->mssql
->getRepository('Entity\MSSQL\TblProperty')
->getProperties($i, $flush_count);
if (count($legacy_properties)===0)
{
break;
}
foreach ($legacy_properties as $legacy_property)
{
// Legacy ID
$legacy_id = $legacy_property['propertyID'];
// Lets see if this property already exists in the new database. If it does, we'll just use that.
$property = $this->doctrine->em
->getRepository('Entity\Beaverusiv\Property')
->findOneBy(array(
'legacy_id' => $legacy_id
));
// If the property from the legacy database does not exist in the new database, let's add it.
if (! $property)
{
$property = new Entity\Beaverusiv\Property; // create a new property instance
$property->setLegacyId($legacy_id);
}
// Update property details
// Set all the other Property fields
$legacy_features = $this->doctrine->mssql
->getRepository('Entity\MSSQL\TblProperty')
->findOneBy(array('propertyID' => $legacy_id))
->getTblPropertyFeaturesJoins();
foreach ($legacy_features as $legacy_feature) {
$feature_id = $legacy_feature->getTblPropertyFeature()->getFeatureID();
$feature = $this->doctrine->em
->getRepository('Entity\Beaverusiv\FeaturesOption')
->findOneBy(array(
'id' => $feature_id
));
$feature_pivot = new Entity\Beaverusiv\PropertiesFeature;
$feature_pivot->setFeaturesOption($feature);
$feature_pivot->setProperty($property);
$this->doctrine->em->merge($feature_pivot);
}
// Persist this property, ready forz flushing in groups of $persist_bunch
$this->doctrine->em->persist($property);
$persist_count++;
// If the number of properties ready to be flushed is the number set in $flush_count, lets flush these properties
if ($persist_count == $flush_count) {
$this->doctrine->em->flush();
$this->doctrine->em->clear();
$this->doctrine->mssql->clear();
}
}
// Flush any remaining properties
$this->doctrine->em->flush();
$i += $flush_count;
}
}
显然这是错误的，但我无法在任何地方找到一个适当的例子。目前它由于某种原因而耗尽内存并抱怨数据透视表中的重复项。如何设置正确的关系，以便我不参考数据透视表，而是直接将FeatureOption添加到Property？
答案 0 :(得分：0)
好的，通过更改属性来设法让它工作：
/**
* @ORM\ManyToMany(targetEntity="FeaturesOption", mappedBy="properties")
*/
protected $featuresOptions;
到此：
/**
* @ORM\ManyToMany(targetEntity="FeaturesOption")
* @ORM\JoinTable(name="properties_features",
* joinColumns={@ORM\JoinColumn(name="property_id", referencedColumnName="legacy_id")},
* inverseJoinColumns={@ORM\JoinColumn(name="feature_id", referencedColumnName="id")}
* )
*/
protected $featuresOptions;
删除数据透视表实体，并删除FeaturesOption实体中的反向引用内容。
