我在Symfony2的MongoDB的學說,這是公驢哎呀,這是我的文檔消氣總是返回NULL
<?php
// srcng/NearBundle/Document/Cities.php
namespace ng\NearBundle\Document;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
/**
* @MongoDB\Document(collection="cities") *
*/
class Cities
{
/**
* @MongoDB\Id
*/
protected $id;
/**
* @MongoDB\string
*/
protected $country;
/**
* @MongoDB\string
*/
protected $name;
/**
* @MongoDB\string
*/
protected $tokens;
/**
* @MongoDB\float
*/
protected $latitude;
/**
* @MongoDB\float
*/
protected $longitude;
/**
* Get id
*
* @return id $id
*/
public function getId()
{
return $this->id;
}
/**
* Set country
*
* @param string $country
* @return self
*/
public function setCountry($country)
{
$this->country = $country;
return $this;
}
/**
* Get country
*
* @return string $country
*/
public function getCountry()
{
return $this->country;
}
/**
* Set name
*
* @param string $name
* @return self
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string $name
*/
public function getName()
{
return $this->name;
}
/**
* Set tokens
*
* @param string $tokens
* @return self
*/
public function setTokens($tokens)
{
$this->tokens = $tokens;
return $this;
}
/**
* Get tokens
*
* @return string $tokens
*/
public function getTokens()
{
return $this->tokens;
}
/**
* Set latitude
*
* @param float $latitude
* @return self
*/
public function setLatitude($latitude)
{
$this->latitude = $latitude;
return $this;
}
/**
* Get latitude
*
* @return float $latitude
*/
public function getLatitude()
{
return $this->latitude;
}
/**
* Set longitude
*
* @param float $longitude
* @return self
*/
public function setLongitude($longitude)
{
$this->longitude = $longitude;
return $this;
}
/**
* Get longitude
*
* @return float $longitude
*/
public function getLongitude()
{
return $this->longitude;
}
}
在我的控制器,當我運行一個查詢,我得到這樣的:
object(ng\NearBundle\Document\Cities)#226 (6) {
["id":protected]=>
string(24) "52e95b6f69eb53d8877f44b5"
["country":protected]=>
NULL
["name":protected]=>
string(4) "Yuma"
["tokens":protected]=>
string(132) "Juma,YUM,Yuma,you ma,yuma,ywma, aryzwna,ywmh,Јума,Юма,יומ×」,یوما، آریزونا,ዩማᥠአሪዞáŠ「,ユマ,尤馬"
["latitude":protected]=>
string(8) "32.72532"
["longitude":protected]=>
string(9) "-114.6244"
}
國家總是空 一個MongoDB的文檔例如:
{
"_id" : ObjectId("52e95b6469eb53d8877eec0c"),
"name" : "'Ali Sabieh",
"tokens" : "Ali Sabie,Ali Sabiet,Ali Sabih,Ali Sabiè,Ali-Sabie,`Ali Sabieh,`Ali Sabih,Али-Сабие,‘Ali Sabieh,‘Ali Sabîẖ",
"country" : "DJ",
"latitude" : 11.15583,
"longitude" : 42.7125
}
你認爲什麼是PROBL他們在這裏?
DB中'country'字段的長度是多少? –
它是2個字符 – Sekai
