I want to find if a $work (string) exist in Works (array), how can I write the request?
public function findByProject($project, $work)
{
return $this->createQueryBuilder('p')
->andWhere('p.project_type = :project')
->andWhere('p.works = :work')
->setParameter('project', $project)
->setParameter('work', $work)
->orderBy('p.id', 'ASC')
//->setMaxResults(10)
->getQuery()
->getResult()
;
}
public function findByProject($project, $work)
{
return $this->createQueryBuilder('p')
->andWhere('p.project_type = :project')
->andWhere('p.works LIKE :work')
->setParameter('project', $project)
->setParameter('work', '%'.$work.'%')
->orderBy('p.id', 'ASC')
//->setMaxResults(10)
->getQuery()
->getResult()
;
}

public function actionFind()

$response = Yii::$app->response;
\Yii::$app->response->format = yii\web\Response::FORMAT_RAW;

why this code has error??
error is :
cannot be displayed because it contains errors
data is property, not function http://www.yiiframework.com/doc-2.0/yii-web-response.html#$data-detail

I've got this table
beds
id
name
size
room
status
hotel
created_at
updated_at
I need to filter all beds that belong to a certain room. In order to do so, I've coded this lines.
public function index()
{
//
$user = JWTAuth::parseToken()->authenticate();
$data = Input::get('room');
if( $data ){
$beds = Bed::where('room', '=', $data )->get();
}else{
$beds = Bed::where('hotel', '=', $user->hostel )->get();
}
foreach( $beds as $bed) {
return $bed->get( array('size','room', 'id') );
}
}
So, If i give it the room id, it should return me only that room's ones.
The thing is that it's returning all table entries.
Any ideas?
UPDATE
Fixed relations and tried this:
return Room::with('beds')->findOrFail($data)->beds;
Now it gives me the number of items.
How can I get the items?
UPDATE
This is the model's code:
class Room extends \Eloquent {
protected $fillable = array('beds', 'price', 'name', 'description','hotel');
public function beds(){
return $this->hasMany('Bed', 'id', 'room');
}
}
UPDATE
The var_dump for:
var_dump( Room::with('beds')->findOrFail($data)->beds );
is:
int(1)
UPDATE
So, the final code is the following.
controller
public function index()
{
//
$user = JWTAuth::parseToken()->authenticate();
$data = Input::get('room');
if( $data ){
$d = intval( $data );
return Bed::where('room', '=', $d )->get( array('size', 'room', 'id', 'name') );
}else{
return Bed::where('hotel', '=', $user->hostel )->get( array('size', 'room', 'id', 'name') );
}
}
model
class Room extends \Eloquent {
protected $fillable = array('beds', 'price', 'name', 'description','hotel');
public function camas(){
return $this->hasMany('Bed', 'room', 'id');
}
}
Thank you guys!
You have quite a few issues in your attempts:
return $bed->get( array('size', 'room', 'id') );
// runs SELECT size, room, id from `rooms`
so it returns all the rooms (why on earth would you like to do this in a foreach anyway?)
return $this->hasMany('Bed', 'id', 'room');
// should be:
return $this->hasMany('Bed', 'room', 'id');
protected $fillable = array('beds', ...
public function beds(){
this is conflict - you will never get a relations when calling $room->beds since you have a column beds on your table.
that said, this is what you need:
public function index()
{
$user = JWTAuth::parseToken()->authenticate();
if(Input::has('room')){
$query = Bed::where('room', '=', Input::get('room'));
}else{
$query = Bed::where('hotel', '=', $user->hostel);
}
return $query->get(['size', 'room', 'id']); // given you need only these columns
}
Try this and see if it works. If not, can you provide the var_dump of Input::get('room') and the structure of the the beds table?
public function index()
{
//
$user = JWTAuth::parseToken()->authenticate();
$data = Input::get('room');
if( $data ){
$beds = Bed::where('room', '=', $data );
}else{
$beds = Bed::where('hotel', '=', $user->hostel );
}
return $beds->get(['size','room', 'id'])->toArray();
}
Better yet if you want to get specific beds in a room and you have your relations set up correctly:
return Room::with('beds')->findOrFail($data)->beds;
EDIT
I saw your update. Are you sure its giving you a number of items, maybe there is one item and the number is the id of it. Can you verify? Please provide a vardump of it if thats not the case. Also can you post your code for the relations in the model?
i want to use result of findall which is array in condition of cactivedataprovider ?
$criteria->condition = 'department_id=:email';
$criteria->params = array(':email'=>$id);
$subject_ids=subject::model()->findAll($criteria);
public function myDataProvider($subject_ids)
{
foreach($subject_ids as $value){
print_r($value);
foreach($value as $val){
echo $val;
}
}
$dataProvider=new CActiveDataProvider('Lecture', array(
'criteria'=>array(
'condition'=>'subject_id='+$val,
)
));
return $dataProvider;
}
how i should use the array has multy rows
You function should looks like
public function myDataProvider($subject_ids)
{
$criteria = new CDbCriteria;
$criteria->compare('subject_id=', $subject_ids);
$dataProvider=new CActiveDataProvider('Lecture', array(
'criteria'=>$criteria
));
return $dataProvider;
}
But $subject_ids is not array of int in your example, so you can do that:
$ids = CHtml::listData(subject::model()->findAll($criteria), 'id', 'id');
and you will get ids.
Is it possible to extract raw sql query from the query builder instance in Phalcon? Something like this?
$queryBuilder = new Phalcon\Mvc\Model\Query\Builder();
$queryBuilder
->from(…)
->where(…);
$rawSql = $queryBuilder->hypotheticalGetRawQueryMethod();
By error and trial the below seems to working. Would be great if someone could confirm if there's a better way.
$queryBuilder = new Builder();
$queryBuilder->from(…)->where(…);
$intermediate = $queryBuilder->getQuery()->parse();
$dialect = DI::getDefault()->get('db')->getDialect();
$sql = $dialect->select($intermediate);
Edit: As of 2.0.3 you can do it super simple, see comment for full details:
$modelsManager->createBuilder()
->from('Some\Robots')
->getQuery()
->getSql()
you can use getRealSqlStatement() (or similar function name) on the DbAdapter. See http://docs.phalconphp.com/en/latest/api/Phalcon_Db_Adapter.html
According to documentation you can get this way the resulting sql query.
Or wait, this might not work on querybuilder. Otherwise you can setup low level query logging: http://docs.phalconphp.com/en/latest/reference/models.html#logging-low-level-sql-statements
$db = Phalcon\DI::getDefault()->getDb();
$sql = $db->getSQLStatement();
$vars = $db->getSQLVariables();
if ($vars) {
$keys = array();
$values = array();
foreach ($vars as $placeHolder=>$var) {
// fill array of placeholders
if (is_string($placeHolder)) {
$keys[] = '/:'.ltrim($placeHolder, ':').'/';
} else {
$keys[] = '/[?]/';
}
// fill array of values
// It makes sense to use RawValue only in INSERT and UPDATE queries and only as values
// in all other cases it will be inserted as a quoted string
if ((strpos($sql, 'INSERT') === 0 || strpos($sql, 'UPDATE') === 0) && $var instanceof \Phalcon\Db\RawValue) {
$var = $var->getValue();
} elseif (is_null($var)) {
$var = 'NULL';
} elseif (is_numeric($var)) {
$var = $var;
} else {
$var = '"'.$var.'"';
}
$values[] = $var;
}
$sql = preg_replace($keys, $values, $sql, 1);
}
More you can read there
The following is the common solution:
$result = $modelsManager->createBuilder()
->from(Foo::class)
->where('slug = :bar:', ['bar' => "some-slug"])
->getQuery()
->getSql();
But you might not expect to see the query without its values, like in:
die(print_r($result, true));
Array
(
[sql] => SELECT `foo`.`id`, `foo`.`slug` FROM `foo` WHERE `foo`.`slug` = :bar
[bind] => Array
(
[bar] => some-slug
)
[bindTypes] =>
)
So, this simple code might be useful:
public static function toSql(\Phalcon\Mvc\Model\Query\BuilderInterface $builder) : string
{
$data = $builder->getQuery()->getSql();
['sql' => $sql, 'bind' => $binds, 'bindTypes' => $bindTypes] = $data;
$finalSql = $sql;
foreach ($binds as $name => $value) {
$formattedValue = $value;
if (\is_object($value)) {
$formattedValue = (string)$value;
}
if (\is_string($formattedValue)) {
$formattedValue = sprintf("'%s'", $formattedValue);
}
$finalSql = str_replace(":$name", $formattedValue, $finalSql);
}
return $finalSql;
}
If you're using query builder then like given below then getPhql function can serve the purpose as per phalcon 3.4.4 version.
$queryBuilder = new Builder();
$queryBuilder->from(…)->where(…)->getQuery();
$queryBuilder->getPhql();
if (!function_exists("getParsedBuilderQuery")) {
/**
* #param \Phalcon\Mvc\Model\Query\BuilderInterface $builder
*
* #return null|string|string[]
*/
function getParsedBuilderQuery (\Phalcon\Mvc\Model\Query\BuilderInterface $builder) {
$dialect = Phalcon\Di::getDefault()->get('db')->getDialect();
$sql = $dialect->select($builder->getQuery()->parse());
foreach ($builder->getQuery()->getBindParams() as $key => $value) {
// For strings work fine. You can add other types below
$sql = preg_replace("/:?\s?($key)\s?:?/","'$value'",$sql);
}
return $sql;
}
}
Simple function that im using for debugging.
Is it possible, when saving a Zend_Db_Table_Row, to make ZF apply a SQL function on one column?
For example, if $row->save() generates by default this SQL query:
UPDATE table SET field = ? WHERE id = ?;
I would like it to automatically apply the GeomFromText() function on this field:
UPDATE table SET field = GeomFromText(?) WHERE id = ?;
Thanks for any hint on how to do this with Zend_Db!
Define a custom update method in your class that inherits from Zend_Db_Table (not from the Zend_Db_Table_Row) and use a Zend_Db_Expr to set the column to the function return value.
See the docs here: http://framework.zend.com/manual/en/zend.db.table.html#zend.db.table.extending.insert-update.
I am just guessing but you could try this:
<?php
class MyTable extends Zend_Db_Table_Abstract
{
protected $_name = 'my_table';
public function update(array $data, $where) {
/**
* Build "col = ?" pairs for the statement,
* except for Zend_Db_Expr which is treated literally.
*/
$set = array();
$i = 0;
foreach ($data as $col => $val) {
if ($val instanceof Zend_Db_Expr) {
$val = $val->__toString();
unset($data[$col]);
} else {
if ($this->_db->supportsParameters('positional')) {
$val = ($col == 'field') ? 'GeomFromText(?)' : '?';
} else {
if ($this->_db->supportsParameters('named')) {
unset($data[$col]);
$data[':col'.$i] = $val;
$val = ($col == 'field') ? 'GeomFromText(:col'.$i.')' : ':col'.$i;
$i++;
} else {
/** #see Zend_Db_Adapter_Exception */
require_once 'Zend/Db/Adapter/Exception.php';
throw new Zend_Db_Adapter_Exception(get_class($this) ." doesn't support positional or named binding");
}
}
}
$set[] = $this->_db->quoteIdentifier($col, true) . ' = ' . $val;
}
$where = $this->_whereExpr($where);
/**
* Build the UPDATE statement
*/
$sql = "UPDATE "
. $this->_db->quoteIdentifier($this->_name , true)
. ' SET ' . implode(', ', $set)
. (($where) ? " WHERE $where" : '');
/**
* Execute the statement and return the number of affected rows
*/
if ($this->_db->supportsParameters('positional')) {
$stmt = $this->_db->query($sql, array_values($data));
} else {
$stmt = $this->_db->query($sql, $data);
}
$result = $stmt->rowCount();
return $result;
}
protected function _whereExpr($where)
{
if (empty($where)) {
return $where;
}
if (!is_array($where)) {
$where = array($where);
}
foreach ($where as $cond => &$term) {
// is $cond an int? (i.e. Not a condition)
if (is_int($cond)) {
// $term is the full condition
if ($term instanceof Zend_Db_Expr) {
$term = $term->__toString();
}
} else {
// $cond is the condition with placeholder,
// and $term is quoted into the condition
$term = $this->quoteInto($cond, $term);
}
$term = '(' . $term . ')';
}
$where = implode(' AND ', $where);
return $where;
}
}
