laravel5-How can i hide the specific column of withPivot? - mysql

I use belongstomany function to get the models and used withPivot() to get an extra column data in the pivot table. However, the withPivot() function will add the 2 foreign keys in the output json. I want to hide thses keys and only show the column I want to display.
The follwing is my response data
{"status_code":"1","next_page":"2","dataset":[{"id":"829","req_start_time":"2016-03-13 14:55:00","req_end_time":"2016-03-13 09:55:00","content":[{"name":"\u9752\u6912\u7092\u725b\u8089","price":"120","pic_url":"","detail":"\u8d85\u7ea7\u597d\u5403\u7684\u54df","pivot":{"waiter_request_id":"829","goods_id":"2","count":"2"}}
as you see the pivot json object contains two id keys.
how could i remove them from the object? or some other ways to solve this get the right way of this need?
thx in advance!
Now the question already upgraded!
How can I add this 'count' parameter of pivot in the object which belongs to 'content'

Finally,I figured out the right way to solve this problem. Follwing the code:
class Goods extends Model{
......
......
public function newPivot(Model $parent, array $attributes, $table, $exists)
{
$pivot = new Pivot($parent, $attributes, $table, $exists);
$pivot->addHidden(
array(
'waiter_request_id',
'goods_id'
)
);
return $pivot;
}
}
you can rewrite this method to provide a new pivot object to the Model in your 'belongsToMany'

Yii2: How to access a table column via a relation

I have two tables, dpd and cabang. One cabang can only have one dpd and each cabang should have a dpd.
This is the relation in my "Cabang" model :
public function getIdDpd()
{
return $this->hasOne(Dpd::className(), ['id_dpd' => 'id_dpd']);
}
I try to access "dpd" attribute in "dpd" table in my view, I tried to var_dump it but still got the same error :
$model = Cabang::find()
->joinWith('idDpd')
->all();
var_dump($model->dpd);
Note : 'dpd' in var_dump($model->dpd) refered to the column name in 'Dpd' table. I have a column name 'dpd' in my 'dpd' table. I also tried $model->idDpd->dpd but it return the same error.
What am I doing wrong? Thanks
Your mistake is
$model->dpd
where you are trying to access it assuming that $model has the Dpd object, but it is holding the Cabang object and you should use the relation name to get the Dpd object and then call the field name like below.
$model->idDpd->dpd
EDIT: You are using ->all() in your query not ->one() and hence you cannot simply do $model->idDpd->dpd right after the query, you need to loop through the records and then call the relation, i thought you might be doing the same way but anyway see below how to use it.
$cabangs = Cabang::find()
->joinWith('idDpd')
->all();
foreach($cabangs as $index=>$model){
$model->idDpd->dpd;
}

Expanding this method to write to the database

Hi I followed a tutorial to implement a friend system. It all works find, but I need to post other columns to the row that just the id's. How would I expand that.
This is the method that is accessed when the add friend button is clicked
public function getAdd($id){
$user = User::where('id', $id)->first();
//After passing all checks. Add other account
Auth::user()->addFriend($user);
echo "Sent";
}
AddTenancy Method
public function addFriend(User $user){
$this->friendsOf()->attach($user->id);
}
I assume the relationship is many-to-many between users. And you need to add additional data to the pivot.
Here's how you'd do that:
public function addFriend(User $user){
$this->friendsOf()->attach($user->id, ['another_col' => 'some data']);
}
Replace 'another_col' and some data with your column and your data. You can also add more than 1 column into the array.

Yii2 - Checkboxlist Value Store In Database

in my db structure
service_request type enum('towel','tissue','napkin')
then have a model
* #property string $service_request
then in my view
<?= $form->field($model, 'service_request')->checkBoxList([ 'towel' => 'Towel', 'tissue' => 'Tissue', 'napkin' => 'Napkin']) ?>
then when i choose towel, tissue and napkin then submit the form, it's have an error said
Service Request must be String
please help me
Thank You
Like Joji Thomas said, checkBoxList prodices an array.
You need to change your database structure so that it supports 1-to-many relations (each $model can have multiple service_requests) if you want to save this. Unfortunately Yii is not very good at this sort of thing out of the box so you have to do a bunch of things yourself.
First you need to create a ServiceRequest ActiveRecord.
Then your $model needs to have a relation like:
public function getServiceRequests() {
return $this->hasMany(ServiceRequest::className(), ['model_id' => 'id'];
}
Then in your controller (model create action) you will need to do something like this:
foreach (Yii::$app->request->post('ServiceRequest',[]) as $data) {
$item = new ServiceRequest($data);
$model->link('serviceRequests', $item);
}
If you wanna update the checkboxes too then you need to do something similar in your model update action as well.
Please change checkBoxList to radioList, because when selecting multiple values service_request becomes an array. Enum type can handle only string values.
First change your filed datatype from enum to varchar. enum only takes a single string value.
Secondly you need to implode service_request array to string for save to db.
Use bellow code before the model save function :
$model->service_request = implode("," , $model->service_request);
$model->save();

Yii model: Dynamic table relations

Table.linkedIndex is related to LinkedIndex.ID. The value of the field LinkedIndex.TableName is either Linked1 or Linked2 and defines which of these tables is related to a row in Table.
Now i want to make a dynamical link with Yii models so that i can easily get from a Table row to the corresponding Linked1 or Linked2 row:
Table.linkedID = [LinkedIndex.TableName].ID
Example
Table values:
LinkedIndex values:
Now I should get the row from Linked2 where ID=2:
$model = Table::model()->findByPk(0);
$row = $model->linked;
Model
In the model Table, I tried to make the relation to the table with the name of the value of linkedIndex.TableName:
public function relations()
{
return array(
'linkedIndex' => array(self::HAS_ONE, 'LinkedIndex', array('ID' => 'linkedIndex')),
'linked' => array(
self::HAS_ONE,
'linkedIndex.TableName',
array('ID' => 'linkedID'),
)
)
}
But then I get the error:
include(linkedIndex.TableName.php) [function.include]: failed to open stream: No such file or directory
Is there any way to make a dynamic relation Table.linkedID -> [LinkedIndex.TableName].ID with Yii Models?
Per the Yii docs here:
http://www.yiiframework.com/doc/api/1.1/CActiveRecord#relations-detail
I'd suggest using self::HAS_ONE instead (unless there can be multiple rows in LinkedIndex with the same ID - although from the looks of above, I doubt that's the case).
You can link tables together that have different keys by following the schema:
foreign_key => primary_key
In case you need to specify custom PK->FK association you can define it as array('fk'=>'pk'). For composite keys it will be array('fk_c1'=>'pk_с1','fk_c2'=>'pk_c2').
so in your case:
public function relations(){
return array(
'linkedIndex' => array(self::HAS_ONE, 'LinkedIndex', array('ID' => 'linkedIndex')),
);
}
where LinkedIndex is the class name for the LinkedIndex model (relative to your Table model - i.e. same folder. You could change that, of course) and array('ID' => 'linkedIndex') specifies the relationship as LinkedIndex.ID = Table.linkedIndex.
Edit
Looking at your updated example, I think you're misunderstanding how the relations function works. You're getting the error
include(linkedIndex.TableName.php) [function.include]: failed to open stream: No such file or directory
because you're trying to create another relation here:
'linked' => array(
self::BELONGS_TO,
'linkedIndex.TableName',
array('ID' => 'linkedID'),
)
This part: linkedIndex.TableName refers to a new model class linkedIndex.TableName, so Yii attempts to load that class' file linkedIndex.TableName.php and throws an error since it doesn't exist.
I think what you're looking for is to be able to access the value TableName within the table LinkedIndex, correct? If so, that's accessible from within the Table model via:
$this->linkedIndex->TableName
This is made possible by the relation we set up above. $this refers to the Table model, linkedIndex refers to the LinkedIndex relation we made above, and TableName is an attribute of that LinkedIndex model.
Edit 2
Per your comments, it looks like you're trying to make a more complex relationship. I'll be honest that this isn't really the way you should be using linking tables (ideally you should have a linking table between two tables, not a linking table that says which 3rd table to link to) but I'll try and answer your question as best as possible within Yii.
Ideally, this relationship should be made from within the LinkedIndex model, since that's where the relationship lies.
Since you're using the table name as the linking factor, you'll need to create a way to dynamically pass in the table you want to use after the record is found.
You can use the LinkedIndex model's afterFind function to create the secondary link after the model is created within Yii, and instantiate the new linked model there.
Something like this for your LinkedIndex model:
class LinkedIndex extends CActiveRecord{
public $linked;
public static function model($className = __CLASS__){
return parent::model($className);
}
public function tableName(){
return 'LinkedIndex';
}
public function afterFind(){
$this->linked = new Linked($this->TableName);
parent::afterFind();
}
//...etc.
}
The afterFind instantiates a new Linked model, and passes in the table name to use. That allows us to do something like this from within the Linked model:
class Linked extends CActiveRecord{
private $table_name;
public function __construct($table_name){
$this->table_name = $table_name;
}
public static function model($className = __CLASS__){
return parent::model($className);
}
public function tableName(){
return $this->table_name;
}
//...etc.
}
which is how we dynamically create a class with interchangeable table names. Of course, this fails of the classes need to have separate operations done per-method, but you could check what the table_name is and act accordingly (that's pretty janky, but would work).
All of this would result in being to access a property of the linked table via (from within the Table model):
$this->linkedIndex->linked->foo;
Because the value of LinkedIndex.TableName and Table.linkedID is needed to get the values, I moved the afterFind, suggested by M Sost, directly into the Table-Class and changed its content accordingly. No more need for a virtual model.
class Table extends CActiveRecord {
public $linked; // Needs to be public, to be accessible
// ...etc.
public function afterFind() {
$model = new $this->linkedIndex->TableName;
$this->linked = $model::model()->findByPk( $this->linkedID );
parent::afterFind();
}
// ...
}
Now I get the row from Linked2 where ID=2:
$model = Table::model()->findByPk(0);
$row = $model->linked;

Magento JoinLeft() in custom orders grid causing SQL integrity constrain violation for non-admin user in multi-website setup

I have extended the Mage_Adminhtml_Block_Sales_Order_Grid class with a custom module to add several customer attributes (Magento EE 1.10) to the grid.
I added the custom attributes to the collection in my MyCompany_MyModule_Block_Adminhtml_Order_Grid class in the _prepareCollection() method using three joins like this:
protected function _prepareCollection()
{
$collection = Mage::getResourceModel($this->_getCollectionClass());
//get the table names for the customer attributes we'll need
$customerEntityVarchar = Mage::getSingleton('core/resource')
->getTableName('customer_entity_varchar');
$customerEntityInt = Mage::getSingleton('core/resource')
->getTableName('customer_entity_int');
// add left joins to display the necessary customer attribute values
$collection->getSelect()->joinLeft(array(
'customer_entity_int_table'=>$customerEntityInt),
'`main_table`.`customer_id`=`customer_entity_int_table`.`entity_id`
AND `customer_entity_int_table`.`attribute_id`=148',
array('bureau'=>'value'));
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_table`.`entity_id`
AND `customer_entity_varchar_table`.`attribute_id`=149',
array('index_code'=>'value'));
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_2_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_2_table`.`entity_id`
AND `customer_entity_varchar_2_table`.`attribute_id`=150',
array('did_number'=>'value'));
$this->setCollection($collection);
return parent::_prepareCollection();
}
UPDATE: While everything displays fine when viewing orders, things are not fine when I try to search / filter orders by any of the text join fields (index_code or did_number). The result is a SQL error: "SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'store_id' in where clause is ambiguous."
This problem also exists if I remove all but one of the leftJoin() statements, so something is going wrong with both (either) of the joins with the customer_entity_varchar table.
As now there are two columns with the name store_id, you have to specify filter_index when you add the column to the grid:
$this->addColumn('store_id', array(
...
'filter_index'=>'main_table.store_id',
));
So that it knows which one you are referring while filtering.
I hope it helps!
More than likely it is because you are joining customer_entity_varchar_table twice.
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_table`.`entity_id`
AND `customer_entity_varchar_table`.`attribute_id`=149',
array('index_code'=>'value'));
$collection->getSelect()->joinLeft(array(
'customer_entity_varchar_2_table'=>$customerEntityVarchar),
'`main_table`.`customer_id`=`customer_entity_varchar_2_table`.`entity_id`
AND `customer_entity_varchar_2_table`.`attribute_id`=150',
array('did_number'=>'value'));
You may want to combine those, you can also try and print the SQL to see what the Query looks like:
$collection->getSelect()->getSelectSql();

The problem appears to exist in two different places. One case is if logged in as a user with a single store, the other as a user who can filter various stores.
Single store user
The solution I went with was to override the addAttributeToFilter method on the collection class. Not knowing exactly what changing the Enterprise_AdminGws_Model_Collections::addStoreAttributeToFilter method would affect other behavior I wanted to avoid that, and I found adding a filter index in Mage_Adminhtml_Block_Sales_Order_Grid as Javier suggested did not work.
Instead I added the following method to Mage_Sales_Model_Resource_Order_Grid_Collection:
/**
* {#inheritdoc}
*/
public function addAttributeToFilter($attribute, $condition = null)
{
if (is_string($attribute) && 'store_id' == $attribute) {
$attribute = 'main_table.' . $attribute;
}
return parent::addFieldToFilter($attribute, $condition);
}

Multi-store user
If a user can filter orders by store at admin/sales_order, the following change is also needed to Mage_Adminhtml_Block_Sales_Order_Grid around line 75:
if (!Mage::app()->isSingleStoreMode()) {
$this->addColumn('store_id', array(
'header' => Mage::helper('sales')->__('Purchased From (Store)'),
'index' => 'store_id',
'type' => 'store',
'store_view'=> true,
'display_deleted' => true,
'filter_index' => 'main_table.store_id',
));
}
A patch can be found here: https://gist.github.com/josephdpurcell/c96286a7c4d2f5d1fe92fb36ee5d0d5a
I had the same bug, after grepping the code, I finally found the troublemaker which is in the Enterprise_AdminGws_Model_Collections class at line ~235:
/**
* Add store_id attribute to filter of EAV-collection
*
* #param Mage_Eav_Model_Entity_Collection_Abstract $collection
*/
public function addStoreAttributeToFilter($collection)
{
$collection->addAttributeToFilter('store_id', array('in' => $this->_role->getStoreIds()));
}
You have to replace 'store_id' by 'main_table.store_id', of course you'll have to extend that particular method in your own rewrite to stick into Magento guidelines :p
Hope it helps!
