I created a relationship between the "Review, Games and Info" tables, unfortunately, though, the main table is Games, and he orders me all for Games, While I would like to order the ID of "review" table.
Models: Review
public function games()
{
return $this->hasMany('App\Models\Giochi', 'id_gioco', 'id');
}
Models: Giochi
public function review()
{
return $this->belongsTo('App\Models\Review', 'id', 'id_gioco');
}
public function infogiochi()
{
return $this->belongsTo('App\Models\InfoGiochi', 'id', 'id_gioco');
}
Models: InfoGiochi
public function games()
{
return $this->hasMany('App\Models\Giochi', 'id', 'id_gioco');
}
Controller:
$review = Giochi::with('Review','InfoGiochi')->orderBy('id','DESC')->get();
Here is a screenshot of my json:
How do I order content for review table IDs?
You have 2 options. You use a join and order in the sql statement or you order it after retrieving the results in the collection.
Using Join
Giochi::select('giocos.*')
->with('Review','InfoGiochi')
->leftJoin('reviews', 'reviews.id', '=', 'giocos.id_gioco')
->orderBy('reviews.id','DESC')
->get();
Sorting Collection
Giochi::with('Review','InfoGiochi')
->get()
->sortByDesc(function($giochi) {
return $giochi->review->id;
});
This would be the shortest version to sort on the collection:
Giochi::with('review')
->get()
->sortByDesc('review.id');
You can modify your relationship query when you fire it:
Giochi::with([
'Review' => function ($query) { return $query->orderBy('id','DESC'); },
'InfoGiochi'
])->orderBy('id','DESC');
You can try with a raw query or you can use ->orderBy() directly on review function.

I'm using datatables from yajra datatables and I have a problem.
I have a datatable where I obtain certain columns from other tables, for example the column "customer" is obtained through a relation from another table
But when I press the sort by customer button, the IDs change to the ID of the table where the relation belongs
This generates errors in the buttons that I have on the right since these IDs do not exist in the "meos" table, only in the "locations" table that is in the relation
How can I make it sort while keeping the same ID it had?
I want to always keep as order criteria the ID of the table I am with, which is the "meos" table belonging to the "meo" class
This is my query
public function query()
{
$languageId = Auth::user()->language_id;
return Meo::with(['businessType' => function ($query) use ($languageId) {
$query->with(['businessTypeDescriptions' => function ($subQuery) use ($languageId) {
$subQuery->where('language_id', '=', $languageId);
}]);
}])->with('location');
}
this is my function getcolumns
protected function getColumns()
{
return [
Column::make('id')->addClass('text-center')->title(__('digestReport.columns.id')),
Column::make('location.location_name')->addClass('text-center')->title(__('digestReport.columns.customer')),
Column::make('businessType')->addClass('text-center')->title(__('digestReport.columns.business_type'))->searchable(false),
Column::computed('action')->exportable(false)->printable(false)->width(160)->addClass('text-center')->title(__('digestReport.columns.actions')),
];
}
please, I need help.
Thanks :)
Try below code. Add ->select() statement
public function query()
{
$languageId = Auth::user()->language_id;
return Meo::with(['businessType' => function ($query) use ($languageId) {
$query->with(['businessTypeDescriptions' => function ($subQuery) use ($languageId) {
$subQuery->where('language_id', '=', $languageId);
}]);
}])->with('location')->select('meo-table.*');
}
Replace meo-table with your database table for Meo::class
I have collections which contains custom products I need to paginate those collections products but I receive error.
data
With this query I can get my collection and it's products but I'm not able to paginate products.
$collection = Collection::where('slug', $slug)->where('status',
'active')->with('products')->first();
With this query I receive error
$collection = Product::with('collections')->whereHas('collections',
function($query) use($slug) { $query->where('slug',
$slug)->where('status', 'active')->first(); });
Error
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'shopping.product_id' doesn't exist (SQL: select * from `collection_products` inner join `product_id` on `collection_products`.`id` = `product_id`.`collection_product_id` where `products`.`id` = `product_id`.`product_id` and `slug` = test and `status` = active limit 1)
Code
Product model
public function collections()
{
return $this->belongsToMany(CollectionProduct::class, 'product_id');
}
Collection model
public function collection(){
return $this->belongsToMany(CollectionProduct::class);
}
public function products(){
return $this->belongsToMany(Product::class, 'collection_products', 'collection_id', 'product_id');
}
CollectionProduct model
public function collection()
{
return $this->belongsTo(Collection::class, 'collection_id','id');
}
Controller default query
public function single($slug){
$collection = Collection::where('slug', $slug)->where('status', 'active')->with('products')->first();
return view('front.collections.single', compact('collection'));
}
Question
How can I get my collection products with pagination ability?
Couple things:
You are trying to call the first() method inside of a relationship query in this line:
$collection = Product::with('collections')->whereHas('collections', function($query) use($slug) { $query->where('slug', $slug)->where('status', 'active')->first(); });
The methods first() and get() are used to execute the query, so you should keep them at the end of the chain of eloquent methods:
$collection = Product::with('collections')
->whereHas('collections', function($query) use($slug) {
$query->where('slug', $slug)->where('status', 'active');
})
->get();
https://laravel.com/docs/5.7/eloquent#retrieving-models
However, if you want to paginate the list of products, then what you really want is the paginate() method:
$collection = Product::with('collections')
->whereHas('collections', function($query) use($slug) {
$query->where('slug', $slug)->where('status', 'active');
})
->paginate(20); // will return 20 products per page
https://laravel.com/docs/5.7/pagination
Also, the collections() method on your Product model has product_id listed as the join table, and is joining to the CollectionProduct model instead of the Collection model.
Try this instead for your Product model:
public function collections()
{
return $this->belongsToMany(Collection::class, 'collection_products', 'product_id', 'collection_id');
}
i use following code and working very well
the first step get product
$product = Product()->find($product_id);
than i get collections and pagination
$collections = Product::find($product_id)->collections->paginate(20);
for example i used above code in this site.
I have tables Polfzms <- Genes
Polfzm model have next relation
public function gene()
{
return $this->belongsTo('App\Gene');
}
I need get all data from Polfzms table with data from Genes table and order it by name from pivot table (Genes). I try next
$data = Polfzm::with([
'gene' => function ($query) {
$query->orderBy('name', 'asc');
},
])->get();
but it not order data by name. How can I do it?
You could try to set this in the relationship definition:
Polfzm.php
public function gene()
{
return $this->belongsTo('App\Gene')->orderBy('name', 'asc');
}
Then in your controller:
$data = Polfzm::with('gene')->get();
If I understand correctly, you could use a collection sortBy helper for this one.
An example could be:
$data = Polfzm::with('gene')
->get()
->sortBy(function ($polfzm) {
return $polfzm->gene->name;
});
I have model with name "Date" which has relationship (one-to-one) with "Tour" and "Tour" Model has relationship (many-to-many) with "Type" Model.
I want to order my Date Records Based on "Type" name. Unfortunately I don't have any clue to do it with eloquent.
Date model:
public function Tour()
{
return $this->belongsTo('\App\Tour');
}
Tour model:
public function Date()
{
return $this->hasOne('\App\Date','tour_id');
}
public function Types()
{
return $this->belongsToMany('\App\Type');
}
Type model:
public function Tours()
{
return $this->belongsToMany('\App\Tour');
}
and my controller for output:
public function tourList()
{
$dates = new Date();
$dates = $dates->orderBy('id','asc')
->paginate(6)
->appends([
'sort_price' => request('sort_price'),
'minmax' => request('minmax'),
'type' => request('type')
]);
return view('primary.Tour.list', compact(['dates']));
}
$dateRes = Date::join('type_tour as TT', 'TT.tour_id', '=', 'date.tour_id')
->join('type as T','TT.type_id','=','T.id')
->orderBy('T.name')
->get();
See if it is work for you.
if you want to order the result based on nested relation column, you must use a chain of joins:
$result= Date::join('tours','tours.id','=','dates.tour_id')
->leftJoin('type_tour','type_tour.tour_id','=','tours.id')
->leftJoin('types','types.id','type_tour.type_id')
->orderBy('types.name')->get();
make sure the relation middle table between tours & types table is type_tour
it might be tour_type or something else ...
please note that if you want to order by multiple columns you could add 'orderBy' clause as much as you want:
->orderBy('Types.id', 'DESC')->orderby('Types.name', 'ASC') //... ext

My Model Items is related to Rooms, which is related to Buildings, which is related to Locations.
Short: Items belongsTo Rooms belongsTo Buildings belongsTo Locations
At the index function of the ItemController I want to show a table of Items. I use Laravel Datatables. It works for 'simple' tables, but I ran into the problem of sorting/searching custom/appended fields, because they are not in the table of course.
Basically I want to join the Room, Building and Location Name for each Item in the displaying table.
This is my Items Model:
protected $appends = [
'building_title',
'location_title',
'room_title',
];
public function getLocationTitleAttribute() {
return $this->room->building->location->title;
}
public function getBuildingTitleAttribute() {
return $this->room->building->title;
}
public function getRoomTitleAttribute() {
return $this->room->title;
}
This is my Controller:
public function anyData()
{
return Datatables::of(Item::query())->make(true);
}
What is the best approach to enable sorting/filtering for appended fields?
Thank you for reading.
This is my solution (no appended fields were used):
public function anyData()
{
$items = Item::join('rooms', 'items.room_id', '=', 'rooms.id')
->join('buildings', 'rooms.building_id', '=', 'buildings.id')
->join('locations', 'buildings.location_id', '=', 'locations.id')
->select([
'items.id',
'items.title',
'items.label_number',
'items.fibu_number',
'rooms.title as room_title',
'buildings.title as building_title',
'locations.title as location_title'
]);
return Datatables::of($items)->make(true);
}
