Conditionaly Laravel Resource - php

Question

TicketResource.php
public function toArray($request) {
return [
'id' => $this->id,
'user_id' => $this->user_id,
'title' => $this->title,
'body' => $this->body,
'status' => $this->status,
'created_at' => $this->created_at->toDateTimeString(),
];
}
CommentResource.php
public function toArray($request) {
return [
'id' => $this->id,
'body' => $this->body,
'user_id' => $this->user_id,
'created_at' => $this->created_at->toDateTimeString()
];
}
TicketController.php
public function index() {
return TicketResource::collection(Ticket::all());
}
public function show(Ticket $id) {
$ticket = $id;
return new TicketResource($ticket);
}
Model Ticket.php
public function comments() {
return $this->hasMany('App\Comment');
}
Model Comment.php
public function ticket() {
return $this->belongsTo('App\Ticket');
}
routes/api.php
Route::get('tickets', 'TicketController#index');
Route::get('tickets/{id}', 'TicketController#show');
I want when I request to tickets/{id} URL, I expect to receive this response:
{
"data": {
"id": 1,
"user_id": 2,
"title": "lorem",
"body": "epsum",
"status": "open",
"created_at": "2020-03-04 18:14:56",
"comments": [
{
"id": 1,
"body": "equi",
"user_id": 1,
"created_at": "2020-03-05 18:14:56",
}
]
}
}
On the contrary, when I visit tickets URL, I don't want the comments to be added on each ticket.
How can I implement that?

Answer 1

You need to add relation
This is my model class:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Category extends Model
{
public function children()
{
return $this->hasMany(Category::class, 'parent_id', 'id')->select('categories.id',
'categories.cid AS key',
'categories.name AS label',
'categories.type',
'categories.lvl');
}
}
in my controller:
$parents = Category::select(
'categories.id',
'categories.id AS key',
'categories.name AS label')->where('lvl', 1)->get();
foreach ($parents as $item) {
$item->children
}
return Response::json($parents, 200, array('Content-Type' => 'application/json;charset=utf8'), JSON_UNESCAPED_UNICODE);
Result:
[
{
"id":2,
"key":2,
"label":"parent label",
"children":[
{
"id":17,
"key":"92697f63-5c50-11ea-80df-5cf9ddf839d3",
"label":"child label",
"type":"Category",
"lvl":2,
}
]
}
]
