So I've been trying to get a second level relation out of my "CategoryResource" but it's not working, here is some of my code :
First, My model :
public function children()
{
return $this->hasMany(Category::class, 'parent_id', 'id');
}
public function sub_children()
{
return $this->hasMany(Category::class, 'parent_id');
}
and then the "CategoryResource" :
$data = [
'id' => $this->id,
'parent_id' => $this->parent_id,
'order' => $this->order,
'name' => $this->name,
'slug' => $this->slug,
'childs' => CategoryResource::collection($this->whenLoaded('children') && $this->whenLoaded('children')),
'created_at' => (string) $this->created_at,
'updated_at' => (string) $this->updated_at,
];
My Controller
return CategoryResource::collection(Category::where('parent_id',null)->with('children.sub_children')->get());
Is there anyway i can retrieve my nested relation through laravel resource ?
You could use with function in the relationship. It would be something like this:
public function children()
{
return $this->hasMany(Category::class, 'parent_id', 'id')
->with('children');
}
It is going to load the children and then "subChildren" as relations of the first object.
So, you are going to load it as:
$children = $originalObject->children;
foreach ($children as $c) {
$subChildren = $c->children;
}
Check if this works for your problem.

I am getting error for undefined method which is defined inside my User model.
My controller:
$inputs = request()->validate([
'title' => 'required|min:8|max:255',
'post_image' => 'file',
'body' => 'required'
]);
auth()->user()->posts()->create($inputs);
My Post model:
public function user() {
return $this->belongsTo('App\Models\User');
}
My User model:
public function posts() {
return $this->hasMany('App\Models\Post');
}
correct your relationship
public function posts() {
return $this->hasMany(Post::class);
}
First your posts relationship is wrong, it must be hasMany NOT belongsTo
public function posts() {
return $this->hasMany(User::class);
}
Then it should work.
You can also try to create the model in a different way:
$validated = request()->validate([
'title' => 'required|min:8|max:255',
'post_image' => 'file',
'body' => 'required'
]);
// Here you should check if $validated has all required fields
// because some could fail, in that case aren't in the array
Post::create([
'title' => $validated['title'],
'user_id' => auth()->id, // or auth()->user->id
'post_image' => $validated['post_image'],
'body' => $validated['body'],
]);

I use laravel 8 & have 3 table:
Products, ProductPrice & ProductsPublisher:
this is my Products model for this relationship:
public function lastPrice(){
return $this->hasMany(ProductPrice::class)->where('status','active')->orderBy('created_at','DESC')->distinct('publisher_id');
}
and this is my productsPrice model for publisher relationship:
public function getPublisher(){
return $this->belongsTo(ProductsPublisher::class,'publisher_id');
}
now, i want to use laravel resource for my api, i wrote products resource:
public function toArray($request)
{
return [
'id' => $this->id,
'price' => lastPrice::make($this->lastPrice),
'status' => $this->status,
'slug' => $this->slug,
'title' => $this->title,
'description' => $this->description,
'txt' => $this->txt,
'lang' => $this->lang,
'created_at' => $this->created_at,
'updated_at' => $this->updated_at,
];
but in lastPrice resource, when i wrote like this:
return [
'id' => $this->id,
'main_price' => $this->main_price
];
it give me this error:
Property [id] does not exist on this collection instance.
when i use this code:
return parent::toArray($request);
get response but because i need to use another relationship in my lastPirce for publishers, i cant use that code and should return separately my data.
What i should to do?
thanks
Edit 1:
this is my Controller Code:
$products = Product::where('id',$id)->where('slug',$slug)->where('status','confirm')->first();
if(!$products){
return $this->sendError('Post does not exist.');
}else{
return $this->sendResponse(new \App\Http\Resources\Products\Products($products), 'Posts fetched.');
}
and this is sendResponse & sendError:
public function sendResponse($result, $message)
{
$response = [
'success' => true,
'data' => $result,
'message' => $message,
];
return response()->json($response, 200);
}
public function sendError($error, $errorMessages = [], $code = 404)
{
$response = [
'success' => false,
'message' => $error,
];
if(!empty($errorMessages)){
$response['data'] = $errorMessages;
}
return response()->json($response, $code);
}
thanks.
Edit 2:
i change my lastPrice Resource toArray function to this and my problem solved, but i think this isn't a clean way, any better idea?
$old_data = parent::toArray($request);
$co = 0;
$new_data = [];
foreach ($old_data as $index){
$publisher_data = Cache::remember('publisher'.$index['publisher_id'], env('CACHE_TIME_LONG') , function () use ($index) {
return ProductsPublisher::where('id' , $index['publisher_id'])->first();
});
$new_data[$co]['main_prices'] = $index['main_price'];
$new_data[$co]['off_prices'] = $index['off_price'];
$new_data[$co]['publisher'] = SinglePublisher::make($publisher_data);
$new_data[$co]['created_at'] = $index['created_at'];
$co++;
}
return $new_data;
I'm developing an API with Laravel. In one of the endpoint I'm accessing, some fields are showing a null value, but it should have some information.
Note the "addicionais_descricao" and "valor" fields, both always come with null values when I include them in the attributeitems array, but if I leave it at the initial level, the data is presented, but it doesn't solve my case, because I need this information with the attribute items:
enter image description here
This is where the endpoint calls, I make the query in the "Attribute" table, which has a relationship with the "Attributeitems" table, while the "attributeitems" table is linked to "Attribute" and "product".
public function show($id)
{
$atributos = Atributo::query('atributo')
->select(
'atributo.id',
'atributo.atrdescricao',
'atributoitens.atributo_id',
'atributoitens.produto_id',
'produto.prodescricao',
'produto.provalor'
)
->leftJoin('atributoitens', 'atributo.id', '=', 'atributoitens.atributo_id')
->leftJoin('produto', 'produto.id', '=', 'atributoitens.produto_id')
->where('atributo.id', '=', $id)
->get()->unique('id');
return AtributoResource::collection($atributos);
}
Resource Atributo:
public function toArray($request)
{
return [
'id' => $this->id,
'descricao' => $this->atrdescricao,
'atributoitens' => AtributoitensResource::collection($this->atributoitens),
];
}
Resource Atributo Itens:
public function toArray($request)
{
return [
'id' => $this->id,
'atributo' => $this->atributo_id,
'produtos' => $this->produto_id,
'adicionais_descricao' => $this->prodescricao,
'valor' => $this->provalor
];
}
What is the correct procedure for this situation?
Take this example as a reference :
Controller
$data = $shop->products()
->whereStatus(true)
->where('product_shop.active', true)
->where('product_shop.quantity', '>=', $this->min_product_qty)
->paginate(50);
return (new ProductCollection($data))
->response()
->setStatusCode(200);
ProductCollection
public function toArray($request)
{
return [
'data' => $this->collection
->map(function($product) use ($request) {
return (new ProductResource($product))->toArray($request);
}),
'brand' => $this->when($request->brand, $request->brand)
];
}
ProductResource
public function toArray($request)
{
return [
'type' => 'product',
'id' => (string) $this->id,
'attributes' => [
'uuid' => $this->uuid,
'name' => $this->name,
'slug' => $this->slug,
'description' => $this->description,
'thumb_path' => $this->thumb_path,
'cover_path' => $this->cover_path,
],
'relationships' => [
'brand' => $this->brand
]
];
}
Something like this should help you do what you want. I cant exactly do it for you. by the way why you are not using Eloquent, something like
Attribute::where(...)->with(['relation_1', 'products'])->get();
public function toArray($request)
{
return [
'id' => $this->id,
'attributes' => [...],
'products' => $this->collection
->map(function($this->product) use ($request) {
return (new ProductResource($product))->toArray($request);
}),
];
}
I setup an api resource collection for the post model, called PostCollection. I have a problem with my comments query for a post. Getting non-object for $comments. The comment table currently has no records.
$author = \App\Post::find(1);
$comments = \App\Post::find(1)->comments;
return [
'id' => $this->id,
'user_id' => $this->user_id,
'description' => $this->description,
'media' => $this->media,
'media_type' => $this->media_type,
'likes' => $this->likes,
'created_at' => $this->created_at,
'updated_at' => $this->updated_at,
'author_avatar' => $author->setting->user_profile_photo,
'author_profile_name' => $author->name,
'author_user_name' => $author->setting->user_name,
'visible' => true,
'comments' => $comments,
];
In the post model, I have:
public function user()
{
return $this->belongsTo(User::class);
}
public function comments()
{
return $this->hasMany(Comment::class);
}
In the comment model I have:
public function user()
{
return $this->belongsTo(User::class);
}
public function post()
{
return $this->belongsTo(Post::class);
}
You should this
public function comments()
{
return $this->hasMany('App\Comment', 'foreign_key', 'local_key');
}
in your controller
$post = \App\Post::find(1);
$comments = $post->comments;
I have the following tables for my many to many relationship: soldhomestests, tasks and soldhomestest_task (as the pivot).
My soldhomestests table has already been populated with data. How do I get my soldhomestest_task pivot table to populate with data upon the creation of a new task that meets conditions in my soldhomestest table? In my example, I want to store the relationship data when the following conditions are met:
'tasks.city' = 'soldhomestests.city'
'tasks.address' = 'soldhomestests.address'
I can't seem to find any documentation on how to proceed with this?
MODELS:
class Task extends Model
{
protected $fillable = [
'address', 'city', 'state',
];
public function user()
{
return $this->belongsTo(User::class);
}
public function soldhomestests()
{
return $this->belongsToMany('App\Soldhomestest');
}
}
class Soldhomestest extends Model
{
public function tasks()
{
return $this->belongsToMany('App\Task');
}
}
CONTROLLER:
public function store(Request $request)
{
$this->validate($request, [
'address' => 'required|max:255',
'city' => 'required|max:255',
'state' => 'required|max:255',
]);
$request->user()->tasks()->create([
'address' => $request->address,
'city' => $request->city,
'state' => $request->state,
]);
return redirect()->route('settings.index');
}
Don't believe this is the Laravel way but I modified my controller to create an array of IDs using the where condition:
public function store(Request $request)
{
$this->validate($request, [
'address' => 'required|max:255',
'city' => 'required|max:255',
'state' => 'required|max:255',
]);
$newtask = $request->user()->tasks()->create([
'address' => $request->address,
'city' => $request->city,
'state' => $request->state,
]);
$condition = DB::table('soldhomestests')->where([
['soldhomestests.address', '=', $request->address],
['soldhomestests.city', '=', $request->city],
])->pluck('id');
$lastid = $newtask->id;
$tasksoldhome = Task::find($lastid);
$tasksoldhome->soldhomestests()->sync($condition);
return redirect()->route('settings.index');
}
Using eloquent, you can do this way.
$task=new Task();
$task->city=$request->city;
$task->address=$request->address;
$task->save();
$soldhometests=Soldhometest::all();
foreach($soldhometests as $soldhometest)
{
if($task->city==$soldhometest->city && $task->address==$soldhometest->address)
{
$soldhometest_task=new SoldhometestTask(); // pivot model
$soldhometest_task->task_id=$task->id;
$soldhometest_task->soldhometest_id=$soldhometest->id;
$soldhometest_task->save();
}
}
