I have JSON data I want to store in a database. Ideally, the data should be automatically decoded when I retreive from the database and automatically encoded when I store in the database.
How can I do this?
Use Accessors and Mutators, for an attribute called foobar add these two functions in your Eloquent model:
public function getFoobarAttribute($value){
return json_decode($value);
}
public function setFoobarAttribute($value){
$this->attributes['foobar'] = json_encode($value);
}

As I understand, mutators change your attribute on save function (create or update). Can I make mutator just for atrribute display to users, but leave default values on save function ?
In Eloquent Model when you do this:
public function getSomeNameAttribute($value)
{
return ucfirst($value);
}
That ^ will mutate the value for showing it later in views and it won't affect what is stored in DB table.
And also if you use a setter setSomeNameAttribute($value) you can pull the actual value from db table with:
$model->getOriginal('attribute_name'); // Laravel V. ^5.*
or
$model->getRawOriginal('attribute_name'); // Laravel V. ^8.*
I'm trying to get the numbers of records from my notifications, where the candidate_user_id column from inside the data attribute is the same as the UserId (Authenticated User).
After I dd, I was able to get the data from all of the records in the table by using the pluck method (Line 1). I then tried to use the Where clause to get the items that I need
but this just didn't work, it was still returning all of the records in the table.
DashboardController.php:
public function index()
{
$notifications = Notification::all()->pluck('data');
$notifications->where('candidate_user_id', Auth::user()->id);
dd($notifications);
}
Here is a partial screenshot of the data that is being plucked.
How can I get the data from this, in a way like this ->where('candidate_user_id', Auth::user()->id);?
If data was a JSON field on the table you could try to use a where condition to search the JSON using the -> operator:
Notification::where('data->candidate_user_id', Auth::id())->pluck('data');
Assuming you only want this data field and not the rest of the fields, you can call pluck on the builder directly. There isn't much reason to hydrate Model instances with all the fields to then just pluck a single field from them if it is just a table field, so you can ask the database for just the field you want.
The data in the data field is a json string, so you can tell Laravel to automatically cast it as an array using the $casts property on each of the models that is notifiable.
For instance, if you have a User model which uses the trait (ie has use Notifiable), add this:
protected $casts = [
'data' => 'array',
];
If you want to access all notifications for the auth user.
$user = auth()->user();
dd($user->notifications->pluck('data'));
If you really want to do in your question way, here is how.
$notifications = Notification::all()->pluck('data');
$notifications = $notifications->where('candidate_user_id', Auth::user()->id)
->all();
This assumes you that you did not modify the default laravel notifications relationship and database migration setup. If you have modified some of the default ones, you need to provide how you modify it.
Using Eloquent L5.1
I'd like to not have to define a set of properties for a model. Instead having everything stored within the database as a serialized column.
In other words any property that is set to this model should before save be removed from the object and added to an array to be serialized and then saved in db to a "data" column.
In turn after retrieving the object from db the model should be hydrated with the de-serialized parameters from the data column.
I could override a good number of Illuminate\Database\Eloquent\Model methods to accomplish this and I'm willing to do so, was curious if anyone had an example of this.
An example of this might be for configuration objects that have virtually unlimited unknown values that have multiple itterations for different objects or for different users.
Put these accessors and mutators in your Model:
class YourModel extends Model
{
public function getDataAttribute($data)
{
return collect(json_decode($data,true));
}
public function setDataAttribute($data)
{
$data = (is_array($data) || is_object($data)) ? json_encode($data) : $data;
return $this->attributes['data'] = $data;
}
}
Now when you can pass data as json string, array or object
YourModel::create(['data'=>'{"working":"ok"}']);
YourModel::create(['data'=>['working'=>'ok']]);
It will work in all three cases.
Im getting various data out of my database.
Product::with('users');
I also have toe execute a complex raw query to get back some information. This is returned as an array.
In my method I would like to get products with users and then add on the data from my raw query to this collection, but this data comes back as an array. Something like:
Product::with('users');
Product->extraData = $rawQuery;
How can I add the raw query output to my Product Collection?
By using Eloquent Facade like Product:: you will get an Eloquent Model object as a result or an Eloquent Collection object as a result, including results retrieved via the get method or accessed via a relationship.
Now, if i understand correctly, you need to add a single extraData property to Eloquent Collection model alongside with Collection items? Or you need to add extraData for each Product ?
If you need to add additional property to Eloquent Collection object, maybe it is a good idea to use a Custom Collection. Please read this section: http://laravel.com/docs/5.1/eloquent-collections#custom-collections .
<?php namespace App;
use App\CollectionWithExtraData;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
public function newCollection(array $models = [])
{
return new CollectionWithExtraData($models);
}
}
And maybe your CollectionWithExtraData can have let's say a
public function setExtraData() {
}
or
public $extraData = array();
If you need extraData for each Product Eloquent Model, just create a new attribute within your Eloquent Model, make it public and set your extra data when needed. Make use of setExtraData() method and $extraData property from above
I'm trying to get my route to insert a new row into the database, and if successful return the record (with its new primary key id) in some JSON. I'm getting the following error:
{
"error":
{
"type":"BadMethodCallException",
"message":"Call to undefined method Illuminate\\Database\\Query\\Builder::to_array()",
"file":"\\vendor\\laravel\\framework\\src\\Illuminate\\Database\\Query\\Builder.php",
"line":1418
}
}
This is my route:
Route::post('/client/create', function()
{
$client = Client::create(Input::all());
if($client)
{
return json_encode(array('Result' => 'OK', 'Record' => $client->to_array()));
}
else
{
return json_encode(array('Result' => 'ERROR', 'Message' => 'Error Inserting Record =('));
}
});
According to the Laravel docs I've read, you're supposed to use ->to_array() to convert your model to an array, and ::create returns an instance of the model if successfully inserted. I've checked the database, and the records are being inserted just fine.
By default if you were to return an Eloquent model directly it would convert the model to it's JSON representation. This is because the __toString magic method on each model returns the model as JSON by using the toJson method.
As such the model implements both the ArrayableInterface and JsonableInterface. That means you can directly call toJson or toArray on a model.
Now you can mark columns as hidden. This means that when a model is converted into it's array or JSON representation some columns are removed (think publicly accessible API, you don't want passwords showing up!). I'm not totally sure but maybe the ID of your model is being hidden.
At the end of the day, all you need to do is return the instance.
return $client;
It'll be converted to JSON for you automatically.
The to_array() method comes from Laravel 3. Use toArray() in Laravel 4.
I see question similar you try to return data to jquery jtable and same me
Player::orderBy($sort)->paginate($pagesize)->getCollection();
return Response::view(array('Result'=>'OK','Records'=>$player->toArray()));
for try many hour I found solution getcollection pull instance from object and then solve
