I am using the laravel polymorphic relation.
cartable model:
public function objectable()
{
return $this->morphTo();
}
instructions model:
public function cartable()
{
return $this->morphMany('PTA_OIMS\Cartable', 'objectable');
}
reports model:
public function reports()
{
return $this->morphMany('PTA_OIMS\Cartable', 'objectable');
}
My instruction table has extra related table called instruction_logs.
But in the reports table, this relationship does not exist.
When my object is report this query has error. Because the reports.report_logs does not exist.
$data = Cartable::where('id', '=', $cartableID)
->with('objectable')
->with('objectable.objectable_logs.attachment') //line error
->with('box.position')
->with('box.assign.staff')
->first();
return $data;
How to handle query if objectable_logs did not exist skip the line error?
$data = Cartable::with([
'objectable',
'objectable.objectable_logs.attachment',
'box.position',
'box.assign.staff'
])->find($cartableID);
return $data;
if attachment is a column in objectable_logs table, it should be like:
$data = Cartable::with([
'objectable',
'objectable.objectable_logs:objectable_id,attachment',
'box.position',
'box.assign.staff'
])->find($cartableID);
return $data;

My Product Model is
public function IncomeRepo(){
return $this->hasMany(Income::class,'Product');
}
My Income Report Model Is
public function ProductData(){
return $this->belongsTo(Product::class,'Product','id');
}
My Query is
public function SearchIncomeData(Request $request){
$GetFromDate = $request->FromDate;
$GetToDate = $request->ToDate;
$ProductData = Product::with('IncomeRepo')->whereBetween('created_at', [$GetFromDate, $GetToDate])->get();
return view('Admin.Report.ProductSalesReport',compact('ProductData'));
}
When I return $ProductData it return products table created_at Data. BUT I nee Income table created_at data which be multiple
How can I get it?
My expectation show incomes table created_at data
If you want to filter data by child tables date then you need to use whereHas relationship.
$GetFromDate = $request->FromDate;
$GetToDate = $request->ToDate;
$ProductData = Product::with('IncomeRepo')
->whereHas('IncomeRepo',function($que) use($GetFromDate,$GetToDate) {
$que->whereBetween('created_at',[$GetFromDate, $GetToDate])})->get();
return view('Admin.Report.ProductSalesReport',compact('ProductData'));
In controller. (Use whereBetween)
public function SearchIncomeData(Request $request)
{
$GetFromDate = $request->FromDate;
$GetToDate = $request->ToDate;
$ProductData = Product::with(['IncomeRepo' => function ($query) use ($GetFromDate, $GetToDate)
{
$query->whereBetween('created_at', [$GetFromDate, $GetToDate]);
}
])->get();
return view('Admin.Report.ProductSalesReport', compact('ProductData'));
}
In view
foreach ($ProductData as $product)
{
foreach ($product->IncomeRepo as $income)
{
echo $income->created_at;
}
}
I couldn't do what I wanted to do with Laravel, actually what I want to do is as follows,
I send getTruck id and list truckHistory with witdh, and I want to pull trukInvoice information with truckHistory invoice_id. But i am getting error where am i doing wrong?
Mysql Connection is as follows.
http://localhost:3000/truck/1
"trucks" table column "plate"
"invoice_details" column "plate_no"
"invoice_details" column "invoice_id"
"invoice" column "id"
Truck Controller
public function getTruck($id)
{
$truck = Truck::find($id)->with([
'truckHistory' => function($query){
// return $query->with(['trukInvoice']);
}
])->first();
return $truck;
}
Truck Model
public function companys()
{
return $this->belongsTo(Contact::class, 'company_id', 'id');
}
public function getCompanyNameAttribute()
{
return $this->companys()->first()->name;
}
public function truckHistory(){
return $this->hasMany(InvoiceDetail::class,'plate_no','plate');
}
public function trukInvoice(){
return $this->belongsTo(Invoice::class,'invoice_id','id');
}
Try this:
$truck = Truck::leftJoin('invoices', 'trucks.invoice_id', 'invoices.id')
->leftJoin('invoice_details', 'trucks.plate_no', 'invoice_details.plate')
->select('*')
->first();
or
$truck = Truck::with(['invoices' => function ($query) {
$query->whereHas('invoice_details', function ($q){
$q->whereNotNull('invoice_details.plate');
});
}])->first();
Check the documentation on restraining eager loads.
I have a query where I get values from 3 tables, for first 2 I use leftJoin, and is Ok, but for third one I try to get an array of objects, and I am not sure how.
In relationship table a have multiple rows for each ID from People table. HasMany type.
$q = Person::leftJoin('registers', 'people.register_id', '=', 'registers.id')
->leftJoin('relationships', 'people.id', '=', 'relationships.person_id') //if I comment this it works for first 2 tables
->find($id);
return response()->json($q);
Person
public function relationship()
{
return $this->hasMany(Relationship::class);
}
public function register()
{
return $this->belongsTo(Register::class);
}
Relationship
public function person()
{
return $this->belongsTo(Person::class, 'person_id');
}
Register
public function people(){
return $this->hasOne(Person::class);
}
UPDATE -> this works,but is kind of ugly, I think that should be a better way in Laravel
$q = Person::leftJoin('registers', 'people.register_id', '=', 'registers.id')
->find($id);
$q2 = Person::find($id)->relationship;
return response()->json([
'values' => $q,
'relationship' => $q2,
]);
You can just use with like this:
Person::with(['register', 'relationship'])->find($id);
I have 3 Tables:
Customers
id
name
Sales
customer_id
sale_date
Contacts
customer_id
contact_date
There aren't any update operations in the contacts table. Each process opens a new record in the contacts table. So, a user can have more than one records in the contacts table.
Here are my relations in models:
Customer
public function contacts()
{
return $this->hasMany(Contact::class);
}
public function sales()
{
return $this->hasMany(Sale::class);
}
Contact
public function customer()
{
return $this->belongsTo('App\Customer', 'customer_id');
}
Sale
public function customer()
{
return $this->belongsTo('App\Customer');
}
I would like to have the latest record of the contacts table and make it join with the other related tables.
Here is the query which I have tried:
$record = Contact::groupBy('customer_id')
->select(DB::raw('max(id)'));
$result = Customer::query();
$result->where('is_active', 'YES');
$result->with('sales');
$result->whereHas('contacts', function ($q) use($record){
return $q->whereIn('id', $record)->where('result', 'UNCALLED');
});
return $result->get();
In the blade file, I get some result in foreach loops. However, I am unable to get the related data from the sales and contacts table.
#foreach($result as $item)
#foreach($item->sales as $sale) // Has no output and gives error: Invalid argument supplied for foreach()
#foreach($item->contacts as $contact) // Has no output and gives error: Invalid argument supplied for foreach()
Can anyone help me how to display the sale and contact date? Or any idea for how to improve this code quality?
If you want the latest record of the contacts you can declare another relationship on the Customer model, e.g.:
public function latest_contact()
{
return $this->hasOne(Contact::class)->latest('contact_date');
}
BTW you can always declare one or more hasOne additional relationship if you have a hasMany in place the foreign key used is the same.
In this way you can retrieve latest_contact eager loaded with your Customer model:
$customer = Customer::with('latest_contact')->find($id);
Or use this relationship in your queries, something like that:
$customers = Customer::where('is_active', 'YES')
->with('sales')
->with('contacts')
->whereHas('last_contact', function ($q){
return $q->where('result', 'UNCALLED');
})->get();
Or that:
$customers = Customer::where('is_active', 'YES')
->with('sales')
->with('contacts')
->with('last_contact', function ($q){
return $q->where('result', 'UNCALLED');
})->get();
If you want you can declare last_contact with the additional where:
public function latest_contact()
{
return $this->hasOne(Contact::class)
->where('result', 'UNCALLED')
->latest('contact_date');
}
This way all other queries should be easier.
I hope this can help you.
I'm not sure, but can you try to do the following:
return Customer::where('is_active', 'YES')
->with([
'sale',
'contact' => function ($query) use($record) {
return $query->whereIn('id', $record)->where('result', 'UNCALLED');
}
])->get();
I am new to make join tables with Eloquent. I want to join 3 tables. But it shows me error. What's my mistake, if anyone notice it will be helpful for me. Here is tables....
In 1st table Applications(id,u_id,program_name) 2nd table StudentInfos(id,u_id,.....) 3rd table users(id,.....)
in Application model
public function StudentInfo()
{
return $this->hasOne('App\StudentInfo', 'u_id', 'u_id');
}
in StudentInfo model
public function User()
{
return $this->hasOne('App\user', 'u_id', 'id');
}
From controller
public function view_application($id)
{
$vu_data = Application::where('id', $id)->get();
$vu_data2 = $vu_data->StudentInfo()->get();
return $vu_data2;
}
$vu_data2 = $vu_data->StudentInfo()->get();
is returning a collection and not just a single Application Model. Change "get()" to "first()", and this will fix your first error. So change:
$vu_data = Application::where('id', $id)->get();
to
$vu_data = Application::where('id', $id)->first();
When you do get(), it returns a collection. You can do :
$vu_data = Application::findOrFail($id);
$student = $vu_data->StudentInfo;
$user = $student->User;
