Well, here is what I did:
public function api_index()
{
$agents=DB::table('users')
->select('id','username','role')
->get();
return response()->json($agents);
}
And its throwing this in browser:
[{"id":"1","username":"suzan","role":"Admin"}, {"id":"2","username":"momta","role":"admin"}]
but i actually needed is i need a json object and on that json object i need these data. may be like this:
{"jsonboject":[{"id":"1","username":"suzan","role":"Admin"},{"id":"2","username":"momta","role":"admin"}]}
How can i do this?
Try this
public function api_index()
{
$agents=DB::table('users')
->select('id','username','role')
->get();
return response(['jsonboject' => $agents]);
}
Do this:
return response()->json(['jsonobject' => $agents]);
Do the following code :
public function api_index()
{
$agents=DB::table('users')
->select('id','username','role')
->get();
return response()->json(array('jsonobject'=>$agents),200);
}

I have a Symfony project where I want to store the all the rows from my MySQL table to JSON. Currently there are five rows in my table, but in my browser it only returns five empty values as {"results":[{},{},{},{},{}]}
I guess I have done something right, but not everything. What am I missing in my code?
#[Route('/budget/api', name: 'budget-api')]
public function index(Request $request, BudgetRepository $repository)
{
$results = $repository->findAll();
return $this->json(['results' => $results]);
}
Try createQueryBuilder its usefull.
#[Route('/budget/api', name: 'budget-api')]
public function index(Request $request, BudgetRepository $repository)
{
$qb = $repository->createQueryBuilder("b");
$results = $qb->getQuery()->getArrayResult();
return $this->json(['results' => $results]);
}
You can use the serializer or re-create the array yourself like that
$courses = $doctrine->getRepository(Course::class)->findByLikeTitle($search, $userId);
foreach ($courses as $key => $course) {
$jsonCourses[$key]['title'] = $course->getTitle();
}
```
You can achieve this by Using a Serializer to convert the array of objects into JSON. There are other ways to achieve this like using jsonResponse for example. But the serializer is the most robust way imo.
Example only:
use Symfony\Component\Serializer\SerializerInterface;
#[Route('/budget/api', name: 'budget-api')]
public function index(Request $request, BudgetRepository $repository, SerializerInterface $serializer)
{
$results = $repository->findAll();
$jsonResults = $serializer->serialize($results, 'json');
//If you need to handle any circular references, you can use this..
$jsonResults = $serializer->serialize($results, 'json', array(
'circular_reference_handler' => function ($object) { return $object; },
));
return $jsonResults;
}
I need to return URL path and name image from database.
This my call method to get data from database:
public function index(){
$rav=Rav::select('id','image','nameravs')->get('image');
return $this->sendResponse($rav->toArray(),'rav show is succesfuly');
}
Output data it look like this:
{
"id": 88,
"image": "1579781806.png",
"nameravs": "asdad"
},
But I want to return image with path URL like this:
"image": http://127.0.0.1:8000/images_ravs/1579781806.png
You can use Eloquent Accessor
add the image url attribute in Rav.php Model like below. then you can access it any place.
public function getImageUrlAttribute($value)
{
return env('APP_URL'). '/images_ravs/' . $this->image;
}
And don't forget to Add Appends property inside the Model
/**
* The accessors to append to the model's array form.
*
* #var array
*/
protected $appends = ['image_url'];
then you can access it like below.
$rav->image_url
Define An Accessor in your model like this example :
public function getImageAttribute($value)
{
return env('APP_URL') . Storage::url($value);
}
Try this:
public function index(){
$rav = Rav::select('id','image','nameravs')->get('image');
return $this->sendResponse(
[
'id' => $rav->id,
'image' => URL::to('/').'/images_ravs/'.rav->image,
'nameravs' => $rev->nameravs
],'rav show is succesfuly');
}
You can use selectRaw or select with DB::raw and just concat that path as a prepended string infront of your image column in your query:
Rav::select(DB::raw("id, nameravs, CONCAT('/images_ravs/', image) as image"))->get()->toArray();
No need to include the URL (unless for some reason you have some type of CDN in front of it) in which case you can just escape the string and add it if necessary.
I would do something like this: Try to use as many od Laravel's built-in functions as possible. In most cases you don't need to reinvent the wheel.
public function index(){
$ravs = Rav::select('id','image','nameravs')->get();
$results = [];
foreach($ravs as $rav){
$rav->image = env('APP_URL') . '/images_ravs/' . $rav->image;
array_push($results, $rav);
}
return response()->json($results);
}
In the Model you can create getAttribute:
public function getImageAttribute()
{
return $this->attributes['image'] ? URL::to('/uploads/' . $this->attributes['image']) : null;
}
Or you can create custom casts file:
protected $casts = [
'image' => ImageCast::class,
'created_at' => 'datetime',
'updated_at' => 'datetime',
];
I have two models in laravel project Item and ItemImgs
Item.php
class Item extends Model
{
protected $appends = [
'photo',
];
public function imgs()
{
return $this->hasMany(ItemImage::class);
}
public function getPhotoAttribute()
{
$img = $this->imgs->first();
return $img.src;
}
}
it's worked in views
dd(Item::all()); //worked
{{ $cane->photo}}; //worked
but when I try to get json
return response()->json([
'items' => Item::with('imgs')->get(),
]);
// not worked. Got timeout 500
You cannot use dot notation in PHP.
public function getPhotoAttribute()
{
$img = $this->imgs->first();
return $img.src; // Dot notation is not allowed
}
but you've to use:
public function getPhotoAttribute()
{
$img = $this->imgs->first();
return $img->src;
}
if what you're trying to do is to get the items that have imgs() then what you should do is query by relationship existence, as mentioned in the docs
https://laravel.com/docs/5.8/eloquent-relationships#querying-relationship-existence
'items' => Item::has('imgs')->get()
It is not possible to refer to the linked model tables in attributes. It works in views but gives out a memory error when outputting an array through json.
public function getPhotoAttribute(){
$img = ItemImage::where('item', $this->id)-
>first();
}
It works that way, but it's not elegant.
I am using yii1. I have following code which converts array into json:
public function actionIndex()
{
/* $this->layout='//layouts/datatable';*/
if(Yii::app()->request->isAjaxRequest) {
$model = Company::model()->findAll();
$data = array_map(function ($model) {
return $model->attributes;
}, $model);
$responce = json_encode($data);
var_dump($responce);
return $responce;
}
else {
return $this->render('list');
}
}
It returns json data string(1221) "[{"c_id":"1","c_name":"Marokand", ...
However, i need json data with the following format:
[{c_id: 1, c_name: "Marokand",
Please, help me.
Use echo instead of var_dump().
Instead of return, i used echo. It gave me expected result.
I'm looking for a way to return a model as JSON including an association model after save (within a controller).
I know how to respond as JSON with associations by doing the following :
$objects = MyModel::with(['assocation1', 'association2.dependencies'])->get();
return response()->json($objects, 200);
But in a case of an object already found ? I've tried to use the same concept as above but it returns every rows.
$object = MyModel::first();
$object->with(['assocation1', 'association2.dependencies'])->get();
Laravel's documentation unfortunately does says much about it. What I'm trying to do is to return a JSON object including an association after save, within a controller :
class ExampleController extends Controller {
public function store()
{
$object = new MyModel($request->input('object'));
$response = DB::transaction(function () use ($object) {
if (object()->save()) {
// Here I want to return the object with association1 as JSON
return response()->json($object->with('association1')->get(), 201);
}
});
return $response;
}
}
Edit
More clarification about this case. Using either with or load seems to produce the same result: returning all rows from the Object object including associations. My goal here is to only return ONE object with it's association as JSON, not all of them.
I believe you aren't as far off as you think. In your second example, you shouldn't call get(). Try this instead:
if ( $object = $object->save() )
{
$object->load(['assocation1', 'association2.dependencies']);
return response()->json($object, 201);
}
