{
return $this->insertGetId($data);
}
// Single search

return $this->where('id',$id)->first()->toArray();
}else{
return [];

}
// How many query users are there uid, Quantity returned
public function countCity($uid){

return $this->where('uid',$uid)->count();
}else{
return [];
}

}
/**

return $this->where('id',$id)->update($data);
}else{
return false;
}
}
// Add conditions and time

public function buy_num($uid){
$startDate = date('Y-m-01', strtotime(date("Y-m-d")));
$endDate = date('Y-m-d', strtotime("$startDate +1 month -1 day"));
// Convert a date to Unix Time stamp
$endDate=$endDate." 22:59:59";
$startDateStr = strtotime($startDate);
$endtDateStr = strtotime($endDate);
return $this->where('uid',$uid)->where('buy_type',1)->whereBetween('create_time', array($startDateStr,$endtDateStr))->sum('buy_num');
}
/**
* According to id Find city information Returns only the value of a field
* @param $id
* @return array
*/
public function getCityName($id)
