I'm using Datamapper ORM for CodeIgniter I have rules 'serialized' and get_rules 'unserialized' for a field in my model. This field will store serialized data and when I retrieve back, get_rules will unserialize it.
However, after calling save(), I'm trying to re-access the field, but it still return serialized string, instead of array.
Is there any way to re-call or refresh my object so that the get_rules is called again and the field now return array?
Here's my model:
class User extends DataMapper{
public $validation = array(
'password' => array(
'label' => 'Password',
'rules' => array('encrypt')
),
'preferences' => array(
'rules' => array('serialize'),
'get_rules'=> array('unserialize')
)
);
function __construct($id = NULL)
{
parent::__construct($id);
}
function post_model_init($from_cache = FALSE)
{
}
public function _encrypt($field)
{
if (!empty($this->{$field}))
{
$this->{$field} = md5($this->{$field});
}
}
}
Datamapper ORM, afaik, will only use the get_rules when actually performing a get(). A few things you could try:
Given the following
$a = new Fruit();
$a->name = 'grapes';
$a->colors = serialize(array("purple","green"));
$a->save();
1. Create a new datamapper object and re-fetch:
$b = new Fruit();
$b->where('id', $a->id)->get();
$colors = $b->colors;
2. unserialize() the field yourself...
$colors = unserialize($a->colors);
3. You might even be able to use get_clone()
//not tested...
$b = $a->get_clone();
$colors = $b->colors;

I'm new to Yii and struggling to get my head around a few things.
I have model with this function:
public static function findNonGeo()
{
$query = new CallerIdentityQuery(get_called_class());
$query->select([
'cidref', 'caller_id', 'expiry', 'conf_call',
'type', 'redirect', 'destination', 'status', 'start_date',
'statusDesc' => new \yii\db\Expression("CASE status
WHEN 0 THEN 'Deactivated'
WHEN 1 THEN 'Active'
WHEN 2 THEN 'Inactive'
WHEN 3 THEN 'Unregistered'
ELSE 'Permanently Deleted' END")])
->where(['status' => '1'])
->andWhere(['type' => 'N'])
->andWhere(['custref' => Yii::$app->user->identity->typedIdentity->getId()]);
return $query;
}
And in my controller I call this method like so:
$model = CallerIdentity::findNonGeo()->where(['cidref' => $id])->one();
but when the data is returned its like its just ignoring the
->andWhere(['type' => 'N'])
because I can view records that aren't of type 'N'.
so I'm having to do in my controller, maybe I'm doing something wrong or just not understanding it but I don't get it:
$model = CallerIdentity::findNonGeo()->where(['cidref' => $id])->andWhere(['type'=>'N'])->one();
another thing when using findOne($id):
$model = CallerIdentity::findOne($id);
null is returned.
Would appreciate any form of explanation/info.
When using where you're setting the where part of the query, not adding to it. So in the findNonGeo function you're building the required where parts. But with CallerIdentity::findNonGeo()->where(['cidref' => $id]) you're removing the already added where parts.
Try like this:
CallerIdentity::findNonGeo()->andWhere(['cidref' => $id])->one();
by using andWhere you'll keep the other parts and just add another one to it.
I have a model that has a one to many relationship to the versions of the description.
In my Controller
$tag = Tags::create([
'name' => $request->get('name'),
'user_id' => \Auth::id(),
]);
$tag->update([
'content' => $request->get('description')
]);
In my Model:
public function setContentAttribute(string $value)
{
$this->versions()->create([
'user_id' => \Auth::id(),
'value' => $value
]);
}
So I can't put content directly as an attribute in the create method because there is no Model right now.
But is it possible to overwrite the create Method?
When I try to overwrite something like this in my Model it will do an infinity loop
public static function create($attr) {
return parent::create($attr);
}
So my question is if it is possible to have something like this:
$tag = Tags::create([
'name' => $request->get('name'),
'user_id' => \Auth::id(),
'content' => $request->get('content')
]);
and in the Model:
public static function create($attr) {
$value = $attr['content'];
$attr['content'] = null;
$object = parent::create($attr);
$object->content = $value;
$object->save();
return $object;
}
Update
I didn't overwrite the create method but called it customCreate. So there is no infinity loop anymore and I can pass all variables to the customCreate function that handles the relationships for me.
Solution
After reading the changes from 5.3 to 5.4 it turns out that the create method was moved so you don't have to call parent::create() anymore.
The final solution is:
public static function create($attr) {
$content = $attr['content'];
unset($attr['content']);
$element = static::query()->create($attr);
$element->content = $content;
$element->save();
return $element;
}
I don't see why not and you could probably implement a more general approach? Eg. checking if set{property}Attribute() method exists, if it does - use it to assign a value, if it doesn't - use mass assigning.
Something like:
public static function create($attr) {
$indirect = collect($attr)->filter(function($value, $property) {
return method_exists(self::class, 'set' . camel_case($property) . 'Attribute');
});
$entity = parent::create(array_diff_key($attr, $indirect->toArray()));
$indirect->each(function($value, $property) use ($entity) {
$entity->{$property} = $value;
});
$entity->save();
return $entity;
}
I haven't really tested it but it should work. I use something like this in one of my Symfony apps.
i have an array as follows
'topic' =>
array (
'id' => 13,
'title' => 'Macros',
'content' => '<p>Macros. This is the updated content.</p>
',
'created_at' => '2014-02-28 18:36:55',
'updated_at' => '2014-05-14 16:42:14',
'category_id' => '5',
'tags' => 'tags',
'referUrl' => '',
'user_id' => 3,
'videoUrl' => '',
'useDefaultVideoOverlay' => 'true',
'positive' => 0,
'negative' => 1,
'context' => 'macros',
'viewcount' => 60,
'deleted_at' => NULL,
)
I would like to use this array and convert/cast it into the Topic Model . Is there a way this can be done.
thanks
Try creating a new object and passing the array into the constructor
$topic = new Topic($array['topic']);
For creating models from a single item array:
$Topic = new Topic();
$Topic->fill($array);
For creating a collection from an array of items:
$Topic::hydrate($result);
Here is a generic way to do it, not sure if there is a Laravel-specific method -- but this is pretty simple to implement.
You have your Topic class with its properties, and a constructor that will create a new Topic object and assign values to its properties based on an array of $data passed as a parameter.
class Topic
{
public $id;
public $title;
public function __construct(array $data = array())
{
foreach($data as $key => $value) {
$this->$key = $value;
}
}
}
Use it like this:
$Topic = new Topic(array(
'id' => 13,
'title' => 'Marcos',
));
Output:
object(Topic)#1 (2) {
["id"]=>
int(13)
["title"]=>
string(6) "Marcos"
}
It seems that you have data of an existing model there, so:
First, you can use that array to fill only fillable (or not guarded) properties on your model. Mind that if there is no fillable or guarded array on the Topic model you'll get MassAssignmentException.
Then manually assign the rest of the properties if needed.
Finally use newInstance with 2nd param set to true to let Eloquent know it's existing model, not instantiate a new object as it would, again, throw an exception upon saving (due to unique indexes constraints, primary key for a start).
.
$topic = with(new Topic)->newInstance($yourArray, true);
$topic->someProperty = $array['someProperty']; // do that for each attribute that is not fillable (or guarded)
...
$topic->save();
To sum up, it's cumbersome and probably you shouldn't be doing that at all, so the question is: Why you'd like to do that anyway?
Look at these two available methods in L5 newInstance and newFromBuilder
e.g with(new static)->newInstance( $attributes , true ) ;
I would likely create the new instance of the object and then build it that way, then you can actually split some useful reusable things or defaults into the model otherwise what's the point in pushing an array into a model and doing nothing with it - very little besides for normalization.
What I mean is:
$topic = new Topic();
$topic->id = 3489;
$topic->name = 'Test';
And the model would simply be a class with public $id;. You can also set defaults so if you had like resync_topic or whatever property, you can set it as 0 in the model rather than setting 0 in your array.
I came across this question looking for something else. Noticed it was a bit outdated and I have another way that I go about handling the OPs issue. This might be a known way of handling the creation of a model from an array with more recent versions of Laravel.
I add a generic constructor to my class/model
public function __construct(array $attributes = [])
{
parent::__construct($attributes);
}
Then when I want to create a new instance of the model from an array I make a call like this
$topic = new Topic($attrs);
// Then save it if applicable
$topic->save(); // or $topic->saveOrFail();
I hope someone finds this helpful.
So i have a model named Customer.
The db the Customer looks like this:
id, name, lastName, personal, address, zip, location, phones, emails updated_at, created_at
Emails and Phones is special rows because they are store as an json object example
['john#doe.com', 'some#othermail.com', 'more#mails.com']
I use the Customer Model to store the validation rules and custom messages like this
<?php
class Customer extends BaseModel
{
public function validationRules()
{
return array(
'name' => 'required|max:255',
'lastName' =>'max:255',
'personal'=> 'integer',
'location' => 'max:255',
'address' => 'max:255',
'zip' => 'required|integer',
'phones' => 'betweenOrArray:8,10|required_without:emails',
'emails' => 'emailOrArray'
);
}
public function validationMessages()
{
// returns Validation Messages (its too much to write down)
}
}
The OrArray Rule is found here https://stackoverflow.com/a/18163546/1430587
I call them through my controller like this
public function store()
{
$customer = new Customer;
$messages = $customer->validationMessages();
$rules = $customer->validationRules();
$input['name'] = Input::get('name');
$input['lastName'] = Input::get('lastName');
$input['personal'] = preg_replace("/[^0-9]/", "", Input::get('personal'));
$input['location'] = Input::get('location');
$input['address'] = Input::get('address');
$input['zip'] = Input::get('zip');
$input['emails'] = Input::get('emails');
$input['phones'] = Input::get('phones');
foreach($input['phones'] as $i => $value)
{
$input['phones'][$i] = preg_replace("/[^0-9]/", "", $value);
}
$validator = Validator::make($input, $rules, $messages);
}
This all works just fine, but I want to be able to PUT/PATCH request to update a single row.
But the validationRules has Required on certain fields so when its not present i cant update that single row. Without getting an error that the other fields (witch I'm not posting) is required.
How would I best approach this ?
You should get that instance of the model that represent the row you want to edit, that's why the resource controller's update method has a parameter that is the resource you want to edit.
public function update($resourceId) {
$customer = Customer::where('id', '=', $resourceId);
}
Now this customer has all the attributes you set before, so you can access them like:
$customer->name;
$customer->lastName;
So when you valide the values you can use the existing values in your validator where the input is empty:
$input['name'] = (Input::get('name')) ? (Input::get('name')) : $customer->name;
Or a prettier solution with the elvis operator:
$input['name'] = (Input::get('name')) ?: $customer->name;
I came up with another solution to this problem that works very well and its much cleaner.
$customer = Customer::find($id);
$input = Input::except('_method', '_token');
$customer->fill($input);
I'm using Symfony 2.1 forms with PropelBundle and I'm trying to refactor a form that had a drop-down list of objects (to select from) to instead use a jquery autocomplete field (working with AJAX). For the dropdown list I was using the following code (which worked perfectly for the drop-down) in my form type:
$builder->add('books', 'collection', array(
'type' => 'model',
'options' => array(
'class' => 'MyVendor\MyBundle\Model\Book',
'property' => 'title',
),
'allow_add' => true,
'allow_delete' => true,
'by_reference' => false,
'required' => false,
));
For the sake of giving a little context, let's say we are creating a new "Reader" object and that we would like to select the Reader's favorite books from a list of available "Book" objects. A collection type is used so that many "favorite books" can be selected in the new "Reader" form. Now, I would like to change the above to use autocomplete. For doing so, I tried to implement a Data Transformer to be able to get a Book object from a simple text field that could be used for the Autocomplete function to pass the Book ID as indicated in the answer to this Question. However, I was not able to figure out how to make the Data Transformer work with a collection type and Propel classes. I created a BookToIdTransformer class as indicated in the Symfony Cookbook and tried the following in the "ReaderType" file:
$transformer = new BookToIdTransformer();
$builder->add(
$builder->create('books', 'collection', array(
'type' => 'text',
'allow_add' => true,
'allow_delete' => true,
'by_reference' => false,
'required' => false,
))->addModelTransformer($transformer)
);
With the above, I get a "Call to undefined method: getId" exception (apparently the Transformer expects a PropelCollection of Books, not a single Book object..). Does anyone know how to go about it? or let me know if there are other ways to implement the autocomplete in Symfony using Propel and allowing for selecting multiple objects (e.g. a collection of books)?
The solution I ultimately went for is slightly different from my previous answer. I ended up using a "text" field type instead of a "collection" field type in my "ReaderType" form, since I ended up using the Loopj Tokeninput jQuery plugin which allows for selecting multiple objects (e.g. "Favorite Book") to associate to my main object (e.g. "Reader" object) in the form. Considering that, I created a "Data Transformer" for transforming the objects' ids passed (in a comma separated list in the text field) into a Propel Object Collection. The code is shared as follows, including a sample ajax object controller.
The key part of the "ReaderType" form looks as follows:
$transformer = new BooksToIdsTransformer();
$builder->add(
$builder->create('books', 'text', array(
'required' => false,
))->addModelTransformer($transformer)
);
The "Data Transformer" file looks like this:
// src/MyVendor/MyBundle/Form/DataTransformer/BooksToIdsTransformer.php
namespace MyVendor\MyBundle\Form\DataTransformer;
use \PropelObjectCollection;
use Symfony\Component\Form\DataTransformerInterface;
use Symfony\Component\Form\Exception\UnexpectedTypeException;
use MyVendor\MyBundle\Model\BookQuery;
class BooksToIdsTransformer implements DataTransformerInterface
{
public function transform($books)
{
if (null === $books) {
return "";
}
if (!$books instanceof PropelObjectCollection) {
throw new UnexpectedTypeException($books, '\PropelObjectCollection');
}
$idsArray = array();
foreach ($books as $book) {
$idsArray[] = $book->getId();
}
$ids = implode(",", $idsArray);
return $ids;
}
public function reverseTransform($ids)
{
$books = new PropelObjectCollection();
if ('' === $ids || null === $ids) {
return $books;
}
if (!is_string($ids)) {
throw new UnexpectedTypeException($ids, 'string');
}
$idsArray = explode(",", $ids);
$idsArray = array_filter ($idsArray, 'is_numeric');
foreach ($idsArray as $id) {
$books->append(BookQuery::create()->findOneById($id));
}
return $books;
}
}
The ajax controller that returns a json collection of "books" to the Tokeninput autocomplete function is as follows:
namespace MyVendor\MyBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use MyVendor\MyBundle\Model\BookQuery;
class ClassAjaxController extends Controller
{
public function bookAction(Request $request)
{
$value = $request->get('q');
$books = BookQuery::create()->findByName('%'.$value.'%');
$json = array();
foreach ($books as $book) {
$json[] = array(
'id' => $book->getId(),
'name' => $book->getName()
);
}
$response = new Response();
$response->setContent(json_encode($json));
return $response;
}
}
And finally, the router in the "routing.yml" file:
ajax_book:
pattern: /ajax_book
defaults: { _controller: MySiteBundle:ClassAjax:book }
