i have this
public function deals(){
$matchThese = [ 'suspended' => 0, 'status' => 1, 'approved' => 1 ];
$deals = ListsDeals::where( $matchThese )->orderBy( 'start_date' )->get();
$list = DB::table( 'lists' )
->join( 'list_has_deals', 'lists.id', '=', 'list_has_deals.list_id' )
->where( 'list_has_deals.deal_id', '=', 12)
->select( 'lists.id' )
->get();
$categories = DB::table( 'lists_categories' )
->join( 'list_has_categories', 'lists_categories.id', '=', 'list_has_categories.category_id' )
->where( 'list_has_categories.list_id', '=', $list[0]->id )
->select( 'lists_categories.title' )
->get();
return view( "deals" )
->with( "deals", $deals )
->with( "categories", $categories );
}
I want to obtain the value of title for the categories in lists, but first i need to obtain the deals for the lists in less words
I have
Deals - Lists - lists_has_deals
Categories - Lists - lists_has_deals
Both are belongsToMany, i want obtain in the deals the categories belonging to the list that is associated with the offer.
In my example that works fine but the 12 need to be a foreach of the $deals not be number static, thanks for the help.
Try using a has many through or intermediate pivot table on lists_has_deals. If I'm understanding your question, lists should have the necessary reference to both deals and categories.

I have a query which returns names of categories and its subcategories.
$subcategories = Subcategory::select('subcategories.name as subcatname', 'categories.name as catname')
->join('categories', 'subcategories.idCategory', '=', 'categories.id')
->get();
And now I get results like:
'Music' => 'Jazz',
'Music' => 'Rock',
'Music' => 'Pop',
'Movie' => 'Action'
How can I group it to have something like this:
'Music' => array('Jazz', 'Rock','Pop'),
'Movies' => array('Action')
Is it possible without making to much looping iterations and checking which subcategory belongs to which category?
You can use laravel collection
First you need to group by groupBy method, then map each group and merge every child array.
$result = collect($subcategories)
->groupBy('catname')
->map(function ($item) {
return array_merge($item->toArray());
})->all();
I am trying to increase the speed of my Laravel 5.4 sql query by using joins, which I've never used before. I currently have the query working and returning results, my issue is that I get like each results around 8 times. Ex: I get the same 2001 Chevrolet Silverado 8 times in my array. If anybody could help me out I would really appreciate it. Thanks
My query + collection:
$tmp = DB::table('inventories'
)->join(
'vehicles', 'vehicles.id', '=', 'inventories.id'
)->join(
'vimages', 'vimages.vehicle_id', '=', 'inventories.id'
)->where(
'inventories.dealer_id', '=', $dealer_id
)->where(
'inventories.is_active', '=', 1
)->where(
'inventories.is_deleted','=', 0
)->select(
'inventories.stock_number','inventories.vehicle_id','vehicles.year','vehicles.make','vehicles.model','vehicles.vin','inventories.vehicle_status',
'inventories.cost','inventories.search_meta','vimages.name'
);
$data = collect();
$pmt = $tmp->get();
// return json_encode( $pmt );
// logger( sprintf('# of rows returned: %s', $pmt->count() ) );
$pmt->each( function($row) use(&$data) {
// logger( sprintf('Row : %s', $row->toJson() ));
$data->push( array(
'stock_number' => $row->stock_number,
'vehicle_id' => $row->vehicle_id,
'year' => $row->year,
'make' => $row->make,
'model' => $row->model,
// 'trim' => $row->trim,
'vin' => $row->vin,
'status' => $row->vehicle_status,
// 'purchase_price' => $row->purchase_price,
'cost' => $row->cost,
// 'retail_price' => $row->retail_price,
'search_meta' => $row->search_meta,
// 'images' => $row->getFirstImage()
'images' => $row->name
// 'interior_color' => $row->vehicle()->first()->interior_color,
// 'exterior_color' => $row->vehicle()->first()->exterior_color,
// 'firstImg' => $row->getFirstImage()
// 'images' => Vimage::select('vehicle_id','name'
// )->where(
// 'dealer_id', '=', $row->dealer_id
// )->where(
// 'vehicle_id', '=', $row->vehicle_id
// )->limit(1)->get()
));
});

I don't see your db table but I think there is problem in first join statment:
you should use
->join('vehicles', 'vehicles.id', '=', 'inventories.vehicle_id' )
instead of
->join('vehicles', 'vehicles.id', '=', 'inventories.id' )
also second join should be like
->join('vimages', 'vimages.vehicle_id', '=', 'vehicles.id')
instead of
->join('vimages', 'vimages.vehicle_id', '=', 'inventories.id')
It sounds trivial but this should work:
$tmp = DB::table('inventories'
)->join(
'vehicles', 'vehicles.id', '=', 'inventories.id'
)->join(
'vimages', 'vimages.vehicle_id', '=', 'inventories.id'
)->where(
'inventories.dealer_id', '=', $dealer_id
)->where(
'inventories.is_active', '=', 1
)->where(
'inventories.is_deleted','=', 0
)->selectRaw("DISTINCT inventories.stock_number, inventories.vehicle_id,
vehicles.year, vehicles.make, vehicles.model, vehicles.vin,
inventories.vehicle_status, inventories.cost,
inventories.search_meta, vimages.name"
);
Update: forgot to delete the single quotes in selectRaw
Figured it thanks to #Devon. Added another where statement to query to only get first image.
Thanks
)->where('vimages.sequence','=', 0
I am having some trouble in Laravel using the query builder to select users based on two where clauses.
The first where clause would contain multiple where statements to select a user based on some conditions. If this fails in the OR part I would like to check simply if the user ID is in the array.
Would be grateful for some advice on how I could achieve this.
Thanks.
$rs = DB::table('tblUser')
->select('name')
->where(function($q) {
$q->where(function($q){
$q->where('fid', '=', $this->argument('fid'))
->where('type', '<', 10)
})
->orWhereIn('id', $userIdSArray);
})
->get();
$userIdSArray = [ '2', '4', '5' ];
$rs = DB::table( 'Users' )
->select( 'name' )
->where( function ( $q ) use ( $userIdSArray ) {
$q->where( function ( $q ) {
$q->where( 'fid', '=', $this->argument( 'fid' ) )
->where( 'type', '<', 10 );
})
->orWhereIn( 'id', $userIdSArray );
})
->get();
I think you need to pass $userIdSArray in Query builder . And You also forgot (;) after [->where( 'type', '<', 10 )]
I have a question i have 4 tables
Deals
Lists
Lists_Galleries
List_has_deals
Lists_has_gallery
I need to obtain the img_src_list what is in the List_Galleries but from deals.
I have this var in this time
$query = ListsDeals::where( $matchDeals )
->where('stock', '>', 0)
->orwhere( $matchOtherDeals )
->whereDate('end_date', '>', date('Y-m-d'))
->limit( 4 )
->offset( 0 )
->orderBy( 'start_date' );
$deals = $query->join( 'list_has_deals', 'deals.id', '=', 'list_has_deals.deal_id' )
->join( 'lists', 'list_has_deals.list_id', '=', 'lists.id' )
->join( 'list_has_gallery', 'lists.id', '=', 'list_has_gallery.list_id' )
->join( 'lists_galleries', 'list_has_gallery.gallery_id', '=', 'lists_galleries.id' )->get();
This Give me the results but how i have the same name in all tables for example title for deals and lists that overwrite the names and dont get the values correct, how i can obtain certain columns without overwrite the others? regards.
UPDATE
This give me always the same deal for all results.
$deals = $query->join( 'list_has_deals', 'deals.id', '=', 'list_has_deals.deal_id' )
->join( 'lists', 'list_has_deals.list_id', '=', 'lists.id' )
->join( 'list_has_gallery', 'lists.id', '=', 'list_has_gallery.list_id' )
->join( 'lists_galleries', 'list_has_gallery.gallery_id', '=', 'lists_galleries.id' )
->select([ 'deals.id as deal_id', 'deals.stock as stock', 'deals.price as price', 'deals.price_reduced as price_reduced', 'deals.img_src as img_src', 'deals.title_deal as deal_title' ])->get();
UPDATE
$deals = $query->join( 'list_has_deals', 'deals.id', '=', 'list_has_deals.deal_id' )
->join( 'lists', 'list_has_deals.list_id', '=', 'lists.id' );
$other = $deals->join( 'list_has_gallery', 'lists.id', '=', 'list_has_gallery.list_id' )
->join( 'lists_galleries', 'list_has_gallery.gallery_id', '=', 'lists_galleries.id' )
->select([ 'deals.id', 'deals.stock', 'deals.price', 'deals.price_reduced', 'deals.img_src', 'deals.title_deal', 'lists_galleries.img_src_list' ])
->addSelect([ 'lists_galleries.img_src_list' ])
->get();
You can use select() to choose only those columns you want, and use aliases to rename any that clash:
$query->select(['lists.title AS title', 'lists_galleries.name AS name', 'lists.id AS id'])->get();
That way you can cherry-pick only those columns you need and deal with clashes easily.
Is there a way to Select all where a join fails:
something like:
// Pseudo
$unit = User::from( 'users' )
->select( 'users.*' )
->whereJoinFails( 'suppliers', 'users.id', '=', 'suppliers.user_id' );
I have tried:
// Returns all users
$unit = User::from( 'users' )
->select( 'users.*' )
->leftJoin( 'suppliers', 'users.id', '=', 'suppliers.user_id' );
and
// Returns all users but the one that doesn't satisfy is duplicated
$unit = User::from( 'users' )
->select( 'users.*' )
->join( 'suppliers', 'users.id', '!=', 'suppliers.user_id' );
Left Join will always display the data on the left side of the join even if it is null. This way you can see all the records that are missing in the suppliers table because it will show up as a null. This should work:
User::from( 'users' )
->select( 'users.*' )
->leftJoin('suppliers', 'users.id', '=', 'suppliers.user_id')
->whereNull('suppliers.user_id')
->get();
Alternative solution for this would be:
$cat = User::whereNotIn('id',
DB::table('suppliers')->distinct()->lists('user_id')
)->get();
but in this case 2 queries to database would be executed, for example:
select distinct `user_id` from `suppliers`;
select * from `users` where `id` not in ('1', '2', '5', '6', '7', '8', '9', '10');
