I'm studying table relation in Laravel6. Here is my code which works but suddenly all records Created_at time displayed the same 2021-08-02 11:34:30. I'm sure that time was right. but I noticed it all same. Could you teach me how to fix please?
I would like to get the products table's created_at.
class ProductController extends Controller {
public function index() {
$products = Product::All();
$products = Product::with('categori')
->join('creators', 'creators.id', '=', 'products.creator_id')
->join('categoris', 'categoris.id', '=', 'products.categori_id')
->join('branches', 'branches.id', '=', 'products.br_id')
->join('users', 'users.id', '=', 'products.user_id')
->join('colors', 'colors.id', '=', 'products.color_id')
->get();
$data = array(
'title' => 'index',
'no' => 1,
'products' => $products,
'created_at' => created_at,
);
return view('product.index',$data);
}
Here is my blade file
{{ $product->created_at->format('Y-m-d H:i:s') }}
UPDATE: Model Produt
use Illuminate\Database\Eloquent\Model;
class Product extends Model {
protected $fillable = ['title','kansu', 'customer', 'memo', 'status', 'memo2', 'color_id', 'creator_id', 'br_id','user_id' ,'categori_id'];
public function categori()
{
return $this->belongsTo(Categori::class);
}
}
Produts Table image
I'm not familiar with format() method. You could try to use PHP date_format() to see if there is any difference.
#Bladeview:
{{ date_format($product->created_at, 'Y-m-d H:i:s') }}

Here is my method available in the controller
public function getProductListAll(){
$products = Product::with('property')
->whereStatus(1)
->where('show', 1)
->where('code', '!=', 1)
->where('is_roketable',true)
->with(['prices_roket' => function ($q) {
return $q->whereNull('user_id');
}]);
$products = $products->whereIn('product_type', ['education', 'consultancy', 'startup']);
$data['products'] = $products->select([
'id', 'name', 'image', 'commission', 'price',
'buy_now', 'type', 'short_desc', 'pricing_desc',
'offer_status', 'period_status', 'period', 'period_frequency',
'endpoint', 'product_type', 'unique_id', 'discount_show_status',
'annual_payment', 'pre_register', 'privacy_status', 'privacy',
'sg_project', 'last_pre_register_date', 'product_desc',
'product_consulting', 'product_status',
])->get();
return response()->json($data);
}
and here is the relationship in my model.
return $this->hasMany(ProductPrice::class)->select('price','created_at','user_id','offer_id')
->orderBy('price')
->where(function ($q) {
$q
->where(function ($q2) {
$q2->whereNull('offer_id');
})
->orWhere(function ($q2) {
$q2->whereNotNull('offer_id');
$q2->where('user_id', auth()->user() ? auth()->user()->id : 0);
});
});
I tried to change my relationship and rewrite it, but when I write select, I cannot access any data. When I remove select, they all come. I can't select at prices relationship.
You can not use ->select() inside your model relationship.
Instead what you can do to limit the selection is by adding it into ->with()
For example
$products = Product::query()
->with(['property' => function ($q) {
$q->select(['price','property.created_at','user_id','offer_id']);
}])
->where( ... )
// no need to add property 'price' inside this select
->select(['id', 'name', 'image', 'commission' ... ])
->get();
I want to get category with all children subcategories and posts where id = category_id.
Posts should be paginated.
In category model I have 2 relations.
public function children() {
return $this->hasMany(self::class, 'parent_id');
}
public function posts() {
return $this->hasMany(Post::class, 'category_id');
}
In controller I have this function
public function getCategoryWithPaginatedPosts($slug, $perPage = null)
{
$columns = ['id', 'parent_id', 'title', 'slug', 'description', 'image'];
$postsColumns = ['category_id','title','text'];
$result = Category::whereSlug($slug)
->select($columns)
->with('children')
->with(['items' => function ($q) use ($postColumns) {
$q->wherePublished(true)
->select($postColumns)
->orderBy('id', 'ASC')
->paginate();
}])
->first();
}
Pagination doesn't work.
I just see that number of items is equal to $perPage parameter (and I have more items), but I don't see paginator inside dd($result->items)
It works like that, though I believe it is not the best way to do that.
So I can do it in few steps.
In first step I retrieve all data from DB and convert models to array, because I don't need models on webpage and I suppose it works faster like that. I would use ->toBase() if it could take mutators and relations from the model.
Second step I convert array into stdClass, because it is more comfortable in blade to work with object rather than with array.
Third step is to paginate items with mypaginate function (manual paginator in AppService Provider).
public function getCategoryWithPaginatedPosts($slug, $perPage = null)
{
$columns = ['id', 'parent_id', 'title', 'slug', 'description', 'image'];
$postsColumns = ['category_id','title','text'];
$result = Category::whereSlug($slug)
->select($columns)
->with('children')
->with(['items' => function ($q) use ($postColumns) {
$q->wherePublished(true)
->select($postColumns)
->orderBy('id', 'ASC');
}])
->first()
->toArray();
$result = Arr::arrayToObject($result);
$result->items = collect($result->items)->mypaginate($perPage);
return $result;
}
you should not use ->first() after ->paginate(), change something like this,
$result = Category::whereSlug($slug)
->select($columns)
->with('children')
->with(['items' => function ($q) use ($postColumns) {
$q->wherePublished(true)
->select($postColumns)
->orderBy('id', 'ASC')
}])
->paginate(20);
I have 3 tables this table is related to, I will call this table with
belanja (parent)
anak_belanja (child)
supplier (has relation with parent)
I can create this relation from parent and child but on table supplier I get an error. Usually I use "with" and I get no error, but now I use query builder and I have a problem
My Belanja Model
public function supplier()
{
return $this->belongsTo(\App\Models\Suplier::class ,'supplier_id');
}
My Anak_Belanja model
public function belanja()
{
return $this->belongsTo(\App\Models\Belanja::class ,'belanja_id');
}
and this is my controller
public function render()
{
$user_id = Auth::user()->id;
$sub = SubRincianUraianKegiatan::where('user_id', $user_id)
->where('id' , $this->newid)
->pluck('uraian', 'id');
$sup = Supplier::all()->pluck('nama' ,'id');
$data = DB::table('belanja AS t')
->select([
't.id',
't.uraian',
't.tgl_belanja',
't.supplier_id',
DB::raw('coalesce(sum(p.harga * p.qty),0) AS total_order')
])
->leftjoin('suplier AS s','t.suplier_id','=','s.id') // on here i think this error
->leftjoin('anak_belanja AS p','p.belanja_id','=','t.id')
->where('sub_id', $this->newid)
->where('uraian', 'like', '%'.$this->search.'%')
->groupBy('t.id')
->groupBy('t.uraian')
->groupBy('t.tgl_belanja')
->groupBy('t.suplier_id')
->paginate(10);
return view('livewire.detail-belanja-lw',
['data' => $data ,
'sup' => $sup,
'sub' => $sub,
]);
}
In my blade I try to add supplier like that
{{$i->supplier->nama}}
but I get an error
Undefined property: stdClass::$supplier
Can someone explain my mistake?
$data = DB::table('belanja AS t')
->select([
't.id',
't.uraian',
't.tgl_belanja',
't.suplier_id',
DB::raw('coalesce(sum(p.harga * p.qty),0) AS total_order'),
DB::raw('s.nama as nama')
])
->leftjoin('suplier AS s','t.suplier_id','=','s.id') // on here i think this error
->leftjoin('anak_belanja AS p','p.belanja_id','=','t.id')
->where('sub_id', $this->newid)
->where('uraian', 'like', '%'.$this->search.'%')
->groupBy('t.id')
->groupBy('t.uraian')
->groupBy('t.tgl_belanja')
->groupBy('t.suplier_id')
->paginate(10);
try this.
I'm writing a code to get nested objects in Laravel. I was wondering if it is possible to write conditions in hasMany or belongsTo.
Here is what I'm doing, that makes the question clear:
$posts = Post::where(
array(
'status' => 'active'
)
)
->orderBy('id', 'asc')
->with(['postResponsibilities' => function($query){
$query->where('status', 'active');
}])
->with(['postRequirements' => function($query){
$query->where('status', 'active');
}])
->with(['postSalaries' => function($query){
$query->where('status', 'active');
}])
->skip($limit * ($page - 1))->take($limit)->get();
So, I have to put nested queries to get only those records whose status is active.
In the Post model, I've written:
public function postRequirements(){
return $this->hasMany('App\Models\PostRequirement', 'post_id');
}
public function postResponsibilities(){
return $this->hasMany('App\Models\PostResponsibility', 'post_id');
}
public function postSalaries(){
return $this->hasMany('App\Models\PostSalary', 'post_id');
}
Is there a way such that I can define status condition inside the nested models?
So that I can write:
$posts = Post::where(
array(
'status' => 'active'
)
)
->orderBy('id', 'asc')
->with('postResponsibilities')
->with('postRequirements')
->with('postSalaries')
->skip($limit * ($page - 1))->take($limit)->get();
I hope the question is clear, thanks
What you can do is apply those conditions inside the relationship methods you put on the Post model, for example:
class Post
{
public function postRequirements() {
return $this->hasMany('App\Models\PostRequirement', 'post_id')
->where('status', 'active');
}
}
Yes it is possible to eager load multiple relationships.
See: https://laravel.com/docs/master/eloquent-relationships#eager-loading
In your case it would be something like:
Post::with('postResponsibilities', 'postRequirements', 'postSalaries')->where()....
I have the following in my Event model in Laravel 4. The reason I am using QueryBuilder and not Eloquent is I need to have links in each column header in my results table in my view, that when clicked, order the results in asc or desc based on that column.
The issue I'm having is, if I use Eloquent, it won't work as most of the data is pulled through via relationships to other tables, so Eloquent can't find the required columns/fields.
public static function getEvents($perPage = 10)
{
$order = Session::get('event.order', 'start_date.desc');
$order = explode('.', $order);
$columns = array(
'events.id as id',
'title',
'locations.city as city',
'suppliers.name as supplier_name',
'venues.name as venue_name',
'start_date',
'courses.price as course_price',
'type',
'status',
'max_delegates as availability',
'tutors.first_name as tutor_first_name',
'tutors.last_name as tutor_last_name',
'contacts.first_name as d_first_name'
);
$events = DB::table('events')
->leftJoin('courses', 'course_id', '=', 'courses.id')
->leftJoin('suppliers', 'supplier_id', '=', 'suppliers.id')
->leftJoin('locations', 'location_id', '=', 'locations.id')
->leftJoin('venues', 'venue_id', '=', 'venues.id')
->leftJoin('event_types', 'event_type_id', '=', 'event_types.id')
->leftJoin('event_statuses', 'event_status_id', '=', 'event_statuses.id')
->leftJoin('tutors', 'tutor_id', '=', 'tutors.id')
->leftJoin('delegate_event', 'delegate_event.event_id', '=', 'events.id')
->leftJoin('delegates', 'delegates.id', '=', 'delegate_event.delegate_id')
->leftJoin('contacts', 'delegates.contact_id', '=', 'contacts.id')->groupBy('events.id')
->select($columns)
->orderBy($order[0], $order[1])
->paginate($perPage);
return $events;
}
If you look at my EventsController at the getOrder method:
public function getOrder($order)
{
Session::put('event.order', $order);
return Redirect::back();
}
You can see I am storing the order in the session and then in my model using that to sort the order of results.
Is there a way to do this in Eloquent the way I need to?
You know you can just add a join() to eloquent right?
So, as an example, if you have users and each user has some blog posts (i.e. user has_many blogs), you can output an eloquent model showing username and blog title, ordered by blog title, as follows:
user::join('blogs', 'blogs.id','=','users.blog_id')
->order_by('blogs.title', 'asc')
->select(array('users.username', 'blogs.title'))
->paginate(10);
