I migrated my database from Sql Server to MongoDB
I want to Join existing customer Table with contact Table .
Customer have multiple contacts . I tried whereRaw lookup
customer collection
{
"_id": 77,
"custid": 93
}
Contact Collection
{"_id":77,"contactid":77,"custid":93,"firstname":"Christy ","lastname":"Lambright" }
{"_id":79,"contactid":79, "custid":93,"firstname":"Marlys ","lastname":"Barry" }
Customer Modal
class custt extends Model
{
use Notifiable;
protected $primaryKey = 'id';
}
Contact Modal
class contact extends Model
{
use Notifiable;
protected $primaryKey = 'id';
In Controller
$cnt = DB::collection("custts")->raw(function($collection)
{
$more_where = [];
$more_where[]['$lookup'] = array(
'from' => 'contacts',
'localField' => 'custid',
'foreignField' => 'custid',
'as' => 'country',
);
return $collection->aggregate($more_where);
});
Error comes --
Empty Results
I tried Lots of options for hasMany and belongstoMany . Not working ...
please suggest
ok , finally found it working
source - https://github.com/jenssegers/laravel-mongodb/issues/841
$cnt = custt::raw(function($collection)
{
return $collection->aggregate(
[[
'$lookup' => [
'as'=>'info',
'from'=>'contacts',
'foreignField'=>'custid',
'localField'=>'custid'
]
]]
);
});

I am working on Yii2. I am using mysql and mssql databases. The mssql is on a remote site and I am able to access it. Now I am trying to add a dropdown list.
Controller
public function actionCreate()
{
$model = new AllowArea();
$sds = Yii::$app->sds->createCommand("Select * from Area")->queryAll();// mssql Database
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
}
return $this->render('create', [
'model' => $model,
'sds' => $sds
]);
}
View
<?= $form->field($model, 'salesman_code')->dropDownList(\common\models\AllowArea::toArrayList(), ['prompt' => 'Select a Booker']) ?>
Model
In my model, I have a function
public static function toArrayList(){
$sds = Yii::$app->sds->createCommand("Select * from Salesmen")->queryAll();
return ArrayHelper::map($sds::find()->all(),'SalesmanCode',function($sds, $defaultValue){
return $sds['SalesmanCode'].' - '.$sds['SalesmanNameFull'];
});
}
Previously I was using self in place of $sds. With $sds I am getting error
Class name must be a valid object or a string
Any help would be highly appreciated
You are not using Model/Class. So, in ArrayHelper
return ArrayHelper::map($sds, 'SalesmanCode', function($sds) {
return $sds['SalesmanCode'].' - '.$sds['SalesmanNameFull'];
});
I have two models TeamMember and ProjectRequest.
A TeamMember can have one ProjectRequest, that is why I created the following Eloquent relationship on TeamMember:
class TeamMember extends Model {
//
protected $table = 'team_members';
protected $fillable = ['project_request_id'];
// Relations
public function projectTeam() {
return $this->hasOne('\App\Models\ProjectRequest', 'project_request_id');
}
}
In my Controller I want to query both tables, however it returns the failure message.
What is important to know is that $request->projectTeam is an array of emails, looking like this:
array:2 [
0 => "mv#something.com"
1 => "as#something.com"
]
Meaning that I need to bulk insert into team_members table the project_request_ id for each team member where the emails are in the array.
How can I do that in the right way? The following is my attempt:
public function createProjectTeam(Request $request){
try {
$title = $request->projectTitle;
$TeamMember = $request->projectTeam;
$projectRequest = ProjectRequest::create(['project_title' => $title]);
$projectRequestId = $projectRequest->id;
$projectTeam = $this->teamMembers->projectTeam()->create(['project_request_id'=> $projectRequestId])->where('email', $TeamMember);
//$projectTeam = TeamMember::createMany(['project_request_id' => $projectRequestId])->where($TeamMember);
//dd($projectTeam);
return $projectRequest.$projectTeam;
} catch(\Exception $e){
return ['success' => false, 'message' => 'project team creation failed'];
}
}
There are a few things you can do.
Eloquent offers a whereIn() method which allows you to query where a field equals one or more in a specified array.
Secondly, you can use the update() method to update all qualifying team members with the project_request_id:
public function createProjectTeam(Request $request)
{
try {
$projectRequest = ProjectRequest::create(['project_title' => $request->projectTitle]);
TeamMember::whereIn('email', $request->projectTeam)
->update([
'project_request_id' => $projectRequest->id
]);
return [
'success' => true,
'team_members' => $request->projectTeam
];
} catch(\Exception $e) {
return [
'success' => false,
'message' => 'project team creation failed'
];
}
}
I hope this helps.
I don't really know what words or terms I would search. I have also read the documentation in laravel 5.7, https://laravel.com/docs/5.7/eloquent-relationships#many-to-many-polymorphic-relations.
But still I couldn't find the thing that I want.
The result that I am expecting is this in MySQL:
SELECT id as product_id, (SELECT name FROM products WHERE id = transactions.product_id), created_at FROM transactions WHERE user_id = 1
This is the result of the mysql query:
I already have a model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Transactions extends Model
{
protected $table = 'transactions';
protected $fillable = [
'user_id', 'product_id'
];
public function product()
{
return $this->hasOne('App\Products')->select('name');
}
}
?>
Then in my controller:
public function transactions()
{
$transactions = new Transactions::where('user_id',Auth::id())->product;
return view('transactions', ['transactions' => $transactions]);
}
You should use belongsTo() relation. Transaction belongs to one product, product has many transactions.
Also, you can (or better should) rename model to a singlular. Then you don't need to use protected $table.
It is not necessarily to select only name.
Transaction model:
namespace App;
use Illuminate\Database\Eloquent\Model;
class Transaction extends Model
{
protected $fillable = ['user_id', 'product_id'];
public function product()
{
return $this->belongsTo('App\Product');
}
}
Controller:
public function transactions()
{
$transactions = Transaction::with('product')
->where('user_id', Auth::id())
->get();
return view('transactions', ['transactions' => $transactions]);
}
View:
#foreach($transactions as $transaction)
echo $transaction->product_id; //attribute product_id of transaction
echo $transaction->product->id; //attribute id of product
echo $transaction->product->name; //attribute name of product
#endforeach
I am having issues with a Laravel application using an existing database where MS SQL UUIDs are used. My application has a customer:
class Customer extends Model
{
protected $table = 'ERP.Customer';
public $timestamps = false;
protected $primaryKey = 'CustID';
protected $keyType = 'string';
protected $fillable = [
'CustID',
'SysRowID',
'CustNum',
'LegalName',
'ValidPayer',
'TerritoryID',
'Address1',
'Address2',
'Address3',
'City',
'State',
'Zip',
'Country',
'SalesRepCode',
'CurrencyCode',
'TermsCode',
'CreditHold',
'FaxNum',
'PhoneNum',
'CustomerType'
];
public function SalesTer()
{
return $this->belongsTo(SalesTer::class,'TerritoryID', 'TerritoryID');
}
public function Shipments()
{
return $this->hasMany(Shipment::class, 'CustNum', 'CustNum');
}
public function Equipments()
{
return $this->hasMany(Equipment::class,'CustNum', 'CustNum');
}
public function Customer_UD()
{
return $this->hasOne(Customer_UD::class,'ForeignSysRowID', 'SysRowID');
}
}
Which (in the native ERP application) has a UD table which end users can used to customise the Customer entity:
class Customer_UD extends Model
{
protected $table = 'ERP.Customer_UD';
protected $primaryKey = 'ForeignSysRowID';
public $timestamps = false;
public $incrementing = false;
protected $keyType = 'string';
protected $fillable = [
'ForeignSysRowID',
'MakesCans_c',
'MakesEnds_c',
'Industry_c'
];
public function Customer()
{
return $this->hasOne(Customer::class,'SysRowID', 'ForeignSysRowID');
}
}
CustomerController:
public function show($CustID)
{
if(Customer::find($CustID))
{
$Customer = Customer::find($CustID);
$Customer_UD = $Customer->Customer_UD()
->get();
$Shipments = $Customer->Shipments()
->where('Voided', '0')
->get();
$Equipments = $Customer->Equipments()
->with('Part') // load the Part too in a single query
->where('SNStatus', 'SHIPPED')
->get();
return view('Customer.show', ['NoCust' => '0'],
compact('Equipments', 'Customer','Shipments', 'Parts', 'Customer_UD'));
}
else
{
return view('Customer.show', ['NoCust' => '1']);
}
}
The Customer has (for whatever reason) a CustID (which people use to refer to the customer) a CustNum (which is not used outside of the database and a SysRowID. The SysRowID is used to link the Customer table with the Customer_UD table.
An example row from Customer_UD is:
My issue is that when trying to return the UD fields along with the Customer fields I get an error:
SQLSTATE[HY000]: General error: 20018 Incorrect syntax near ''.
[20018] (severity 15) [select * from [ERP].[Customer_UD] where [ERP].
[Customer_UD].[ForeignSysRowID] = '���_�X�O�Q3�^w' and [ERP].
[Customer_UD].[ForeignSysRowID] is not null]
I thought it was odd, so I commended out the Customer_UD lines in the CustomerController and simply tried to display the Customer UUID field in the show blade:
SysRowID: {{$Customer->SysRowID}}
I get nothing, no errors but no data. I created a controller and index blade for the Customer_UD model and can display all of the Customer_UD database fields apart from the UUID field.
I don't actually want to display the UUID fields - but do need to use them to build the relationships. Can anyone help point me in the right direction?
I found that adding:
'options' => [
PDO::DBLIB_ATTR_STRINGIFY_UNIQUEIDENTIFIER => true,
],
To the database configuration in config\database.php resolved the issue.
I need to update the database table according to the edited data.
controller
public function update(Request $request)
{
$subscriptionplan = SubscriptionPlan::find($request->id);
$subscriptionplan->update($request->all());
return back();
}
But nothing happens when I submit the form. When I use dd($request->all()); at the beginning of the function, it correctly shows the edited data as follows.
array:10 [▼
"_method" => "patch"
"_token" => "gOCL4dK6TfIgs75wV87RdHpFZkD7rBpaJBxJbLHF"
"editname" => "SUP_EVA_001"
"editdesc" => "des"
"editprice" => "1000.050"
"editlimit" => "1"
"editperunit" => "20.000"
"editexceedunit" => "30.000"
"productid" => "1"
"id" => "1"
]
But database has not been updated.
My table name is Table: subscription_plans and model is SubscriptionPlan
These are the table columns:
protected $fillable = [
'name',
'description',
'price',
'usage_limit',
'charge_per_unit',
'charge_per_unit_exceed',
'is_limit_exceed_considered',
'product_id'
];
Any idea on how to solve it or what I have done wrong?
If your solution did not work, try the 1by1 like this.
public function update(Request $request)
{
$subscriptionplan = SubscriptionPlan::find($request->id);
$subscriptionplan->_method = $request->_method;
$subscriptionplan->_token = $request->_token;
$subscriptionplan->editname = $request->editname;
$subscriptionplan->editdesc = $request->editdesc;
$subscriptionplan->editprice = $request->editprice;
$subscriptionplan->editlimit = $request->editlimit;
$subscriptionplan->editperunit = $request->editperunit;
$subscriptionplan->editexceedunit = $request->editexceedunit;
$subscriptionplan->productid = $request->productid;
$subscriptionplan->save();
return back();
}
In order for Laravel to automatically fill the model attributes, the indexes of the array passed to the fill method must correspond to your model attributes names.
Also, instead of
$subscriptionplan->update($request->all());
Use
$subscriptionplan->fill($request->all());
Then save the subscription plan with $subscriptionplan->save();
