Invoice model
protected $fillable = ['invoice_number', 'created_by', 'coupon_id', 'total_transaction', 'service_charge'];
public function created_by()
{
return $this->belongsTo('App\User', 'created_by');
}
User model
protected $fillable = [
'name', 'email', 'password', 'address', 'phone', 'user_status_id', 'email_activation_token', 'role_id'
];
public function invoice()
{
return $this->hasMany('App\Models\Invoice', 'created_by');
}
User has many Invoice, Invoice belongs to User
Here is my controller
$invoice = new Invoice();
$invoice->invoice_number = '#INV' . $latestInvoiceId + 1;
$invoice->created_by()->associate(Auth::user());
$invoice->total_transaction = $invoice_total;
$invoice->save();
But I get this
ErrorException in BelongsTo.php line 91:
Undefined property: App\Models\Invoice::$created_by

I need help please, to figure out for convenient ways to link between User/Staff/Parent/Student.
A Staff/Parent/Student is a user.
A Staff can be a Parent too. Similarly, a Parent may be a Staff too.
A student belongsToMany Parent, and a Parent belongsToMany Student.
Here are the models I've created :
App\Models\Student.php
protected $fillable = [
'name',
'email',
'student_user_id',
'created_at',
'updated_at',
'deleted_at',
];
public function student_user()
{
return $this->belongsTo(User::class, 'student_user_id');
}
public function guardians()
{
return $this->belongsToMany(StudentGuardian::class);
}
==========================================================
App\Models\StudentGuardian.php
protected $fillable = [
'name',
'email',
'guardian_user_id',
'is_staff',
'guardian_staff_id',
'created_at',
'updated_at',
'deleted_at',
];
public function students()
{
return $this->belongsToMany(Student::class);
}
public function guardian_user()
{
return $this->belongsTo(User::class, 'guardian_user_id');
}
public function guardian_staff()
{
return $this->belongsTo(Staff::class, 'guardian_staff_id');
}
=====================================
App\Models\Staff.php
protected $fillable = [
'name',
'email',
'staff_user_id',
'staff_guardian_id',
'is_student_guardian',
'created_at',
'updated_at',
'deleted_at',
];
public function staff_user()
{
return $this->belongsTo(User::class, 'staff_user_id');
}
public function staff_guardian()
{
return $this->belongsTo(StudentGuardian::class, 'staff_guardian_id');
}
In the StudentsController, I don't know how to call the students related to the authenticated user
you can use polymorphic relation to handle it.

I'm working on a questionnaire project and I ran into an error saying:
Undefined index: exams
This happened when I was trying to store responses to my database.
Here is my controller code:
public function store(Math $math)
{
$data = request()->validate([
'responses.*.answer_id' => 'required',
'responses.*.question_id' => 'required'
]);
$exam = $math->exams()->create($data['exams']);
$exam->examanswers()->createMany($data['examanswers']);
return 'Thank You';
}
Here is my exam model:
{
use HasFactory;
protected $fillable = ['exam'];
public function math()
{
return $this->belongsTo(Math::class);
}
public function examanswers()
{
return $this->hasMany(ExamAnswer::class);
}
}
question model:
{
use HasFactory;
protected $fillable = ['question'];
public function math()
{
return $this->belongsTo(Math::class);
}
public function answers()
{
return $this->hasMany(Answer::class);
}
}
Math model:
{
use HasFactory;
protected $fillable = [
'user_id', 'title', 'purpose', 'exam'
];
public function user()
{
return $this->belongsTo(User::class);
}
public function questions()
{
return $this->hasMany(Question::class);
}
public function exams()
{
return $this->hasMany(Exam::class);
}
}
Please help me look into it.
request()->validate(RULES) will return an array with all the existing rules' indexes. It will not return all data present, just what it is in the rules and present.
Read how $request->validate() works.
For example:
If you send home = 'Address', name = 'John' and email = 123, but your rules are:
$data = $request->validate([
'home' => 'required',
'name' => 'required',
]);
Then, if you want to use $data you would have (dd($data)):
$data['home']: Address
$data['name']: John
But email = 123 would not be present in $data.
Please take a look at this screenshot
that is the result from this
salesItem product_id = {{ $salesItem->product_id }}
and this
wh2summary ={{$salesItem->wh2sum}}
How can I access the qty_in in the long result from wh2sum? I can see the qty_in but if i do this {{$salesItem->wh2sum->qty_in}}
i get this error
my Salesitems model

My Order Model
class Order extends Model
{
protected $fillable = [
'id','user_id', 'erp_id', 'currency_code','ex_rate_with_base','order_status','status','created_at'
];
protected $hidden = ['updated_at',];
public function orderList(){
return $this->hasMany(OrderList::class);
}
public function currency(){
return $this->belongsTo(Currency::class,'currency_code');
}
}
My Currency Model
class Currency extends Model
{
protected $fillable = [
'currency_code','currency_name', 'currency_symbol', 'ex_rate_with_base', 'update_via', 'status',
];
protected $hidden = [
'created_at','updated_at','updated_by','created_by',
];
protected $primaryKey = 'currency_code';
public $incrementing = false;
public function order()
{
return $this->hasMany(Order::class,'currency_code');
}
}
My OrderList Model
class OrderList extends Model
{
protected $fillable = [
'id','order_id', 'product_code', 'qty','unit_price','status',
];
protected $hidden = [
'created_at' ,'updated_at',
];
public function order(){
return $this->belongsTo(Order::class);
}
}
In my Order controller I want to run the query:
$order_history_list = Order::where([['user_id', $user->id], ['updated_at','>', $updated_at]])
->with([
'currency' => function ($query) {
$query->select('currency_code','currency_symbol','ex_rate_with_base');
},
'orderList' => function ($query) {
$query->select('id','order_id', 'product_code', '***order_lists.qty * orders.ex_rate_with_base AS unit_price_with_ex_rate***','status');
}
])->get();
But error is occuring due to the highlighted portion.
Error: Unknown column 'order_lists.qty * orders.ex_rate_with_base' in 'field list'
Please help me with the correct syntax
How can I use column of order table in the sub query ?
Use DB::raw in your select statement and add a join to the 'orderList' $query
$order_history_list = Order::where([['user_id', $user->id], ['updated_at','>', $updated_at]])
->with([
'currency' => function ($query) {
$query->select('currency_code','currency_symbol','ex_rate_with_base');
},
'orderList' => function ($query) {
$query->select('id','order_id', 'product_code', DB::raw('order_lists.qty * orders.ex_rate_with_base AS unit_price_with_ex_rate'),'status')
->join('orders','order_lists.order_id', 'orders.id');
}
])->get();
My Final Query That Worked:
$order_history_list = Order::where([['user_id',$user->id],['updated_at','>',$updated_at]])
->with(['currency'=>function($query){
$query->select('currency_code','currency_symbol','ex_rate_with_base');
},'orderList' => function($query){
$query->select('order_lists.id','order_lists.order_id', 'order_lists.product_code', 'order_lists.qty','order_lists.unit_price',DB::raw('he_order_lists.qty* he_orders.ex_rate_with_base AS unit_price_with_ex_rate'),'order_lists.status')->join('orders','order_lists.order_id', 'orders.id');
}])->get();
In my model i added protected $table, but when i'm going to use it laravel does't use it. This is my role models:
class Role extends Model
{
protected $table = 'role';
protected $primaryKey = 'ROLE_ID';
protected $casts = [
'ACTIVE' => 'boolean',
];
protected $fillable = [
'ROLE', 'ACTIVE', 'TYPE'
];
public $timestamps = false;
public function groups()
{
return $this->belongsToMany(Group::class, GroupRole::class, 'ROLE_ID', 'GROUP_ID');
}
}
And this is Group model:
class Group extends Model
{
protected $table = 'groups';
protected $primaryKey = 'GROUP_ID';
protected $fillable = [
'GROUP_ID', 'GROUP_NAME', 'PARENT_GROUP', 'ACTIVE'
];
protected $casts = [
'ACTIVE' => 'boolean',
];
public $timestamps = false;
public function type()
{
return $this->belongsTo(GroupType::class, 'TYPE', 'TYPE_ID');
}
public function roles()
{
return $this->belongsToMany(Role::class, GroupRole::class, 'GROUP_ID', 'ROLE_ID');
}
}
And this is group_role table model. It handles many to many relation between role and group:
class GroupRole extends Model
{
protected $table = 'group_role';
protected $primaryKey = 'GROUP_ROLE_ID';
protected $fillable = [
'COMMENT', 'ROLE_ID', 'GROUP_ID'
];
public $timestamps = false;
}
Problem begin when i want to use this models. For example:
$role = App\Role::first();
$groups = $role->groups;
Laravel returns this error messages:
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'favian_mydb.App\GroupRole' doesn't exist (SQL: select groups.*, App\GroupRole.ROLE_ID as pivot_ROLE_ID, App\GroupRole.GROUP_ID as pivot_GROUP_ID from groups inner join App\GroupRole on groups.GROUP_ID = App\GroupRole.GROUP_ID where App\GroupRole.ROLE_ID = 1)
I tried to replace App\GroupRole with group_role and executing in mysql. It works fine. Am i missing something?
The Problem is in your roles relation:
public function roles()
{
return $this->belongsToMany(Role::class, GroupRole::class,'GROUP_ID','ROLE_ID');
}
The belongsToMany expects the intermediate table name as second argument, not the class name.
So you have to define it like this:
public function roles()
{
return $this->belongsToMany(Role::class, 'group_role','GROUP_ID','ROLE_ID');
}
I think the problem is in you relation functions. Try to use strings instead of Model::class.
Example:
return $this->return $this->belongsTo('App\GroupType', 'TYPE', 'TYPE_ID');
Hope this works.
