Php Symfony2 Doctrine2-按条令:映射:导入从现有数据库生成一对多注释

Php Symfony2 Doctrine2-按条令:映射:导入从现有数据库生成一对多注释,php,database,symfony,orm,doctrine-orm,Php,Database,Symfony,Orm,Doctrine Orm,我希望通过使用用于逆向工程的条令工具从现有数据库生成实体 /* * SET FOREIGN_KEY_CHECKS=0; -- ---------------------------- -- Table structure for `country` -- ---------------------------- DROP TABLE IF EXISTS `country`; CREATE TABLE `country` ( `id` int(11) unsigned N

我希望通过使用用于逆向工程的条令工具从现有数据库生成实体

/*

通过执行以下两个命令,您可以要求Doctrine导入模式并构建相关的实体类

1$
php应用程序/控制台原则:映射:导入AcmeBlogBundle注释
2$
php应用程序/控制台原则:生成:实体AcmeBlogBundle

但现在,该学说只在多个仅“ProviderCountry”表中检测到多个同一关系

如果我需要添加OneToMany关系,我必须手动添加注释,添加以下注释

在Provider.php中添加

/**
 * @ORM\OneToMany(targetEntity="ProviderCountry", mappedBy="providerId", cascade={"persist"})
 */
private $datas;
在ProviderCountry.php中添加

    /**
     * @var Provider
     *
     * @ORM\ManyToOne(targetEntity="Provider", inversedBy = "datas")
     * @ORM\JoinColumn(name="providerId", referencedColumnName="id")
     */

private $userid;

那么,我如何通过条令命令生成一对多注释呢?这是条令orm库中的更改

您可以通过更改

供应商/doctor/orm/lib/doctor/orm/Mapping/Driver/DatabaseDriver.php

替换以下语句

foreach ($foreignKeys as $foreignKey) {
          $foreignTable = $foreignKey->getForeignTableName();
          $cols = $foreignKey->getColumns();
          $fkCols = $foreignKey->getForeignColumns();

          $localColumn = current($cols);
          $associationMapping = array();
          $associationMapping['fieldName'] = $this->getFieldNameForColumn($tableName, $localColumn, true);
          $associationMapping['targetEntity'] = $this->getClassNameForTable($foreignTable);

          if ($primaryKeyColumns && in_array($localColumn, $primaryKeyColumns)) {
          $associationMapping['id'] = true;
          }

          for ($i = 0; $i < count($cols); $i++) {
          $associationMapping['joinColumns'][] = array(
          'name' => $cols[$i],
          'referencedColumnName' => $fkCols[$i],
          );
          }

          //Here we need to check if $cols are the same as $primaryKeyColums
          if (!array_diff($cols, $primaryKeyColumns)) {
          $metadata->mapOneToOne($associationMapping);
          } else {
          $metadata->mapManyToOne($associationMapping);
          }
          }
foreach($foreignKey作为$foreignKey){
$foreignTable=$foreignKey->getForeignTableName();
$cols=$foreignKey->getColumns();
$fkCols=$foreignKey->getForeignColumns();
$localColumn=当前($cols);
$associationMapping=array();
$associationMapping['fieldName']=$this->getFieldNameForColumn($tableName,$localColumn,true);
$associationMapping['targetEntity']=$this->getClassNameForTable($foreignTable);
if($primaryKeyColumns&&in_数组($localColumn,$primaryKeyColumns)){
$associationMapping['id']=true;
}
对于($i=0;$i$cols[$i],
“referencedColumnName”=>$fkCols[$i],
);
}
//这里我们需要检查$cols是否与$primarykeycolms相同
if(!array_diff($cols,$primaryKeyColumns)){
$metadata->mapOneToOne($associationMapping);
}否则{
$metadata->MAPMANYTONE($associationMapping);
}
}
改为

foreach ($foreignKeys as $foreignKey) {
            $foreignTable = $foreignKey->getForeignTableName();
            $cols = $foreignKey->getColumns();
            $fkCols = $foreignKey->getForeignColumns();

            $localColumn = current($cols);
            $associationMapping = array();
            $associationMapping['fieldName'] = $this->getFieldNameForColumn($tableName, $localColumn, true);
            $associationMapping['targetEntity'] = $this->getClassNameForTable($foreignTable);

            for ($i = 0; $i < count($cols); $i++) {
                $associationMapping['joinColumns'][] = array(
                    'name' => $cols[$i],
                    'referencedColumnName' => $fkCols[$i],
                );
            }
            $metadata->mapManyToOne($associationMapping);
        }

        foreach ($this->tables as $tableCandidate) {
            if ($this->_sm->getDatabasePlatform()->supportsForeignKeyConstraints()) {
                $foreignKeysCandidate = $tableCandidate->getForeignKeys();
            } else {
                $foreignKeysCandidate = array();
            }

            foreach ($foreignKeysCandidate as $foreignKey) {
                $foreignTable = $foreignKey->getForeignTableName();

                if ($foreignTable == $tableName && !isset($this->manyToManyTables[$tableCandidate->getName()])) {

                    $fkCols = $foreignKey->getForeignColumns();
                    $cols = $foreignKey->getColumns();


                    $localColumn = current($cols);

                    $associationMapping = array();
                    $associationMapping['fieldName'] = $this->getFieldNameForColumn($tableCandidate->getName(), $tableCandidate->getName(), true);
                    $associationMapping['targetEntity'] = $this->getClassNameForTable($tableCandidate->getName());
                    $associationMapping['mappedBy'] = $this->getFieldNameForColumn($tableCandidate->getName(), $localColumn, true);

                    try {
                        $primaryKeyColumns = $tableCandidate->getPrimaryKey()->getColumns();
                        if (count($primaryKeyColumns) == 1) {
                            $indexColumn = current($primaryKeyColumns);
                            $associationMapping['indexBy'] = $indexColumn;
                        }
                    } catch (SchemaException $e) {

                    }

                    $metadata->mapOneToMany($associationMapping);
                }
            }
        }
foreach($foreignKey作为$foreignKey){
$foreignTable=$foreignKey->getForeignTableName();
$cols=$foreignKey->getColumns();
$fkCols=$foreignKey->getForeignColumns();
$localColumn=当前($cols);
$associationMapping=array();
$associationMapping['fieldName']=$this->getFieldNameForColumn($tableName,$localColumn,true);
$associationMapping['targetEntity']=$this->getClassNameForTable($foreignTable);
对于($i=0;$i$cols[$i],
“referencedColumnName”=>$fkCols[$i],
);
}
$metadata->MAPMANYTONE($associationMapping);
}
foreach($this->tables as$tableCandidate){
如果($this->\u sm->getDatabasePlatform()->supportsForeignKeyConstraints()){
$foreignKeysCandidate=$tableCandidate->getForeignKeys();
}否则{
$foreignKeysCandidate=array();
}
foreach($foreignKeysCandidate作为$foreignKey){
$foreignTable=$foreignKey->getForeignTableName();
if($foreignTable==$tableName&&!isset($this->manyToManyTables[$tableCandidate->getName())){
$fkCols=$foreignKey->getForeignColumns();

$associationMapping['targetEntity']=$this->getClassNameForTable($tableCandidate->getName());
$associationMapping['mappedBy']=$this->getFieldNameForColumn($tableCandidate->getName(),$localColumn,true);
试一试{
$primaryKeyColumns=$tableCandidate->getPrimaryKey()->getColumns();
if(计数($primaryKeyColumns)==1){
$indexColumn=当前($primaryKeyColumns);
$associationMapping['indexBy']=$indexColumn;
}
}捕获(SchemaException$e){
}
$metadata->mapOneToMany($associationMapping);
}
}
}
现在,如果运行条令:映射:导入

您将找到一个omany注释

然后运行条令:生成:实体


你会发现双方的关系都是单向的

非常感谢,伙计,这正是我想要的!
