I have three tables: realties, room_types and realty_room_type:
realty_room_type
----------------
id
realty_id
room_type_id
room_type
----------------
id
code
In my Realty model I set a rooms() relationship:
public function rooms()
{
return $this->hasMany(Room::class);
}
I am trying to eager load the rooms() relationship using the with() method. I want to custom what is returned from the relationship, so I am passing a callback function like this:
$realty = Realty::
where('id', $realtyId)
->with([
'rooms' => function ($query) use ($realtyId) {
$query
->leftJoin('room_types', 'room_types.id', '=', 'realty_room_type.room_type_id')
->selectRaw('code, COUNT(*)')
->groupBy('code');
}
])
->get()
);
The problem is I get an empty collection when accessing the relationship using $realty->rooms. Any idea why?
However if I dump and die the statements of the callback function like this:
Realty::
where('id', $realtyId)
->with([
'rooms' => function ($query) use ($realtyId) {
dd($query
->leftJoin('room_types', 'room_types.id', '=', 'realty_room_type.room_type_id')
->selectRaw('code, COUNT(*)')
->groupBy('code'));
}
])
->get()
);
I get what I'd like to be in the rooms() relationship.
Thank you in advance.
You don't need to return inside callback function and call get(). Here you can find the details.
$realty = Realty::
where('id', $realtyId)
->with([
'rooms' => function ($query) use ($realtyId) {
$query
->leftJoin('room_types', 'room_types.id', '=', 'realty_room_type.room_type_id')
->selectRaw('code, COUNT(*)')
->groupBy('code');
}
])
->get();

Wondering if there is a way to use closure on a relationship in order to filter the whole line if there isn't a value which corresponds?
Example code:
foreach ($paiementMethods as $value) {
$giftCards = GiftCard::with(['userEntered', 'userEmployee', 'client', 'payement', 'payement.payementMethods' => function($query) use ($value)
{
$query->where('id', $value);
}])
->where('date','>=', $dateStart)
->where('date','<=', $dateEnd)
->orderBy('updated_at', 'desc')->get();
$giftCardsCollection = $giftCardsCollection->merge($giftCards);
}
}
In this example, if $query->where doesn't find a row for the payement.payementMethods which matches the $value, I want the giftCard to return null. The result I get is the giftCard with only the relation on payement.payementMethods being empty.
My other solution would be to query the giftCard and after that checking the $value to see if I have to include the giftCard in the collection or not.
Best regards
I think using whereHas, it can be solved
$giftCards = GiftCard::with(['userEntered', 'userEmployee', 'client', 'payement', 'payement.payementMethods'])
->whereHas( 'payement.payementMethods', function($query) use ($paiementMethods) {
$query->whereIn('id', $paiementMethods);
})
->where('date','>=', $dateStart)
->where('date','<=', $dateEnd)
->orderBy('updated_at', 'desc')
->get();
This works but it gives all the fields of account table but only few are required.
$data = Loan::select('*')
->with([
'member' => function ($query) {
$query->addSelect('id', 'name');
},
'member.account'
])
->get();
This gives account: null
$data = Loan::select('*')
->with([
'member' => function ($query) {
$query->addSelect('id', 'name');
},
'member.account'=> function ($query) {
$query->addSelect('id', 'account'); // if this line is commented, all the fields are returned but I just need few fields.
}
])
->get();
Member model:
public function account()
{
return $this->hasOne(Account::class);
}
Account model:
public function member()
{
return $this->belongsTo(Member::class);
}
How can I get only the required fields of account table?
You can define the relationship and set it to give you specific columns like this.
on Member model
public function account()
{
return $this->hasOne(Account::class)->select(['id', 'account']);
}
You can try to define required fields in with:
$data = Loan::select('*')
->with([
'member' => function ($query) {
$query->addSelect('id', 'name');
},
'member.account:id,number'
])
->get();
Your are close you just need to select the foreign key column that points to your account model , I guess it would be account_id, So you basically need to select 3 columns from your table which are select(['id', 'name','account_id'])
$data = Loan::with(['member' => function ($query) {
$query->select(['id', 'name','account_id'])
->with(['account'=> function($query){
$query->select(['id','name']);
}]);
}])
->get();
So if you have another nested relation account -> type and you need specific columns from type so you need to select the foreign key column from accounts models as
with(['account'=> function($query){
$query->select(['id','name','type_id'])
->with(['type'=> function($query){
$query->select(['id','name']);
}]);
}]);
I have a model with a related collection
now im doing this query
$data = DeliveryPartner::when($filter, function ($q) use ($request) {
})
->with(['orders' => function ($query) {
$query
->where('delivery_partner_invoice_id', '=', '')
->orWhereNull('delivery_partner_invoice_id')
->whereIn('status', ['payment-accepted', 'completed', 'full-refund', 'partial-refund']);
}])->get();
Now i am wondering. If the orders returns empty is it posible to remove this parent from the collection?
I Know i can do this after the eloquent query with a loop. But is it possible to do this in the query?
we cant completely remove that parent ( with index ) BUT you can set those to null using transform() like this;
$data = DeliveryPartner::when($filter, function ($q) use ($request) {
})
->with(['orders' => function ($query) {
$query
->where('delivery_partner_invoice_id', '=', '')
->orWhereNull('delivery_partner_invoice_id')
->whereIn('status', ['payment-accepted', 'completed', 'full-refund', 'partial-refund']);
}])->get()->transform(function($item){
if(!$item->orders->count() ){
return;
}
return $item;
});
Note: this will not completely remove those parents but it will set them to empty.
I have two tables with belongsToMany relation: message_topics and users
The pivot table is message_topics_users and contains 2 columns: message_id and user_id.
In table message_topics, I have a field called sender_id
I'm trying to write the correct eloquent syntax to get all the records:
where message_topics.sender_id = $user_id
OR Message_topics_users.receiver_id = $user_id
I tried many things, like for instance:
$topics = MessageTopic::where('sender_id', $user_id)
->wherePivot('receiver_id', $user_id)->orderBy('sent_at','desc')->get();
Any idea?
You can use the whereHas method (or in this case the orWhereHas method):
$topics = MessageTopic::where('sender_id', $user_id)
->orWhereHas('users', function ($query) use ($user_id) {
$query->where('id', $user_id);
})
->orderBy('sent_at', 'desc')
->get();
I'm assuming you have two relationships from the topics? Since it's too arbitrary to use both columns and the same relationship... Like this
//On your MessageTopic model
public function sender(){
return $this->belongsToMany('App\User', 'message_topics_users', 'message_id', 'sender_id');
}
public function receiver(){
return $this->belongsToMany('App\User', 'message_topics_users', 'message_id', 'receiver_id'));
}
Then you can use whereHas and orWhereHas like this:
//Again assuming you have your User model loaded as $user
$topics = App\Topic::whereHas('sender', function($q) use($user){
$q->where('sender_id', '=', $user->id);
})
->orWhereHas('receiver', function($q) use($user){
$q->where('receiver_id', '=', $user->id
})
->orderByDesc('sent_at')
->get();
whereHas and orWhereHas both query the model (MessageTopic in this case) checking for the existence of the specified relationship (App\Topic::whereHas('sender')...). They also allow you to pass the constraint that you're looking for (function($q) use($user){ $q->... })
So it is basically saying "Give me ONLY the MessageTopics that have a Sender or Receiver with the id $user->id"
I'm trying to access company variable in laravel eloquent relationship but i'm getting error undefined variable.
Controller
$assignedCases = AddressCaseAssign::with(['addresses' => function ($query) {
$query->where('company_id', '=',$request->company);
}])->where('user_id',$request->executive)
->get();
Model
public function addresses(){
return $this->belongsTo(Address::class,'address_id');
}
You need to pass $request in where clause using use keyword:
$assignedCases = AddressCaseAssign::with(['addresses' => function ($query) use ($request) {
$query->where('company_id', '=',$request->company);
}])->where('user_id',$request->executive)
->get();
