Mongodb using SQL style

Configuraton add setting in config/database.php of laravel
Authorization Database default as admin if no value [options][authen_db]

'mongodb' => [
    'driver' => 'mongodb',
    'host' => env('MONGO_DB_HOST', '127.0.0.1'),
    'port' => env('MONGO_DB_PORT', 27017),
    'database' => env('MONGO_DB_DATABASE', 'marcompany'),
    'username' => env('MONGO_DB_USERNAME', 'maradmin'),
    'password' => env('MONGO_DB_PASSWORD', 'password'),
    'options' => [     
        'authen_db' => env('DB_AUTHENTICATION_DATABASE', 'admin'),
    ],
],

Run Nantabury/Mongodb standalone without laravel :

if you don't have laravel wasn't installed you have only base on composer package go to create file .env under project's directory and then copy all below to .env

# Nantaburi .env file 

MONGO_DB_HOST='127.0.0.1'
MONGO_DB_PORT='27017'
MONGO_DB_DATABASE='products'
MONGO_DB_USERNAME='root'
MONGO_DB_PASSWORD='password'

Using Laravel for SQL query style example below
- Create Model - using command php artisan make:model UserDbModel at laravel root project and insert use Nantaburi\Mongodb\MongoNativeDriver\Model on top
  - ex-fillable used to be protected $fillable = ["useid","username","lastname","password"] will replace with $schema as example below
  - Example : protected $schema [ "userscollection" , ["useid","username","lastname","password"] ]
  - Magic create index with two ways
    - first way : add array with key [ Index => true ] if you want to add option Unique just add more key [ 'Index' => true , 'Unique' => true ]
    - secound way : do multiple keys with create key "$__MULTIPLE_INDEX_01" on same level of collection change at the end _01 to be other once you have more one multiple keys you can use _02 even _AB support as well
  - Magic create collection for counters auto increasement number by add 'AutoInc' => true , and also have option 'AutoInc' => true , 'AutoIncStartwith' => 10, default datatype as double max number can be 2^1023
  - Magic creation of Index and Magic counter will auto create affective once you run first insert or you can do [NameModel]::InitIndexAutoInc()
    - Example : run at Laravel controller just first time or do change schema UserModel::InitIndexAutoInc()
- to protect update option add 'UpdateProtected'=>true once you inserted and do you want to protect update such as price , ID Card number , you can put option example idcard => [ 'UpdateProtected'=>true ] into option of that field

Where comparison operation
- to comparison macthing field to use function format ->where( $field , $Operator , $value) for $Operator list see below table

Operator	description	Example
"="	`operator matches documents where the value of a field equals the specified value`	`->where("userid","=",100)`
">"	`selects those documents where the value of the field is greater than (i.e. >) the specified value`	`->where("userid",">",5)`
">="	`selects the documents where the value of the field is greater than or equal to (i.e. >=) a specified value (e.g. value.)`	`->where("userid",">=",5)`
"in"	`The "in" operator selects the documents where the value of a field equals any value in the specified array. To specify an "in" expression`	`->where("userid","in",[5,11,10])`
"nin"	`The "nin" operator selects the documents where the value of a field equals any value not in the specified array. To specify an "nin" expression`	`->where("userid","nin",[5,11,10])`
"<"	`< selects the documents where the value of the field is less than (i.e. <) the specified value.`	`->where("userid","<",5`
"<="	`<= selects the documents where the value of the field is less than or equal to (i.e. <=) the specified value.`	`->where("userid","<=",10)`
"!="	`!= selects the documents where the value of the field is not equal to the specified value. This includes documents that do not contain the field.`	`->where("username","!=","Supachai")`
"like"	`!= selects the documents where the value of the field is like machting values.`	`->where("username","like","Supa%")` `->where("username","like","%chai")` `->where("username","like","%upa%")`

spacial command on function select()

Operator	description	Example
count(*)	`count all documents to be number`	`->select('count(*)')->get()`

- spacial functions

class function()	description	Example
[ClassName]::getSequence([Auto Increase field],[Collection])	`to auto increase number`	`ModelDB::collection("customers")->insert(["id" => ModelDB::getSequence('id','customers') , "description" => "Elon mask"]) ;`

Create Laravel controller
- using command php artisan make:controller --model=UserDbModel at laravel root project
- then edit and insert basic SQL example : select * from user where username like 'suphacha%' and age > 18 or mooban = 'Pangpoi' ;
- using SQL transform to mongodb showing below :

use App\UserDbModel ; 

   $users= UserDbModel::query()
                         ->where("username" , "like" , "suphacha%" )
                         ->andwhere("age" ,">", 18)
                         ->orwhere("mooban" ,"=" ,"Pangpoi" )
                         ->get() ;
                         
   return view('userlist')->with("users",$users) ;

Changing database and collection if you have permission of user and password on the same multiple databases you can change database difference in file ./config/database.php
- examples change just database DataBaseModel::database("shopping") .... , change database and collection DataBaseModel::database("shopping","products") ...

 
   $prods = CompanyDB::database("shopping")
                                    ->select("id as prod_id","name as prod_name")
                                    ->get()
                                    
   $users = CompanyDB::database("authentication","users")->select("id"," name as prod_name")
                                  ->get()

switch collection don't need to re-create new other Model file
- put begin with ->collection('[Collection Name]') see example below

<?php

namespace App\Http\Controllers;
use App\CompanyModel;
 
          $users =  CompanyModel::collection("users")
                                ->where( "username" ,"=" , "suppachai")
                                ->get();

          $products = CompanyModel::collection("products")
                                ->where( "pid" ,"=" , "101")
                                ->get();

          // Laravel's blade view to displays
          return view("usermanage" )->with('users',$users)
                                    ->with('products',$products); 
               
    }

switch collection don't need to re-create new other Model file
- put begin with ->collection('[Collection Name]') see example below
- and many way to get data

<?php

namespace App\Http\Controllers;
use App\CompanyModel;
 
          $users =  CompanyModel::collection("users")
                                ->where( "username" ,"=" , "shppachai")
                                ->get();

          $products = CompanyModel::all() ;
          
          $login =  CompanyModel::collection("products")->where( "id" ,"=" , 101)->first();

          // Laravel's blade view to dispale
          return view("usermanage" )->with('users',$users)
                                    ->with('products',$products); 
               
    }

Controller
- join collectios code example below
- once you use groupby() request select() all of fields same fields in groupby() if seleted fields are not be field's member in groupby() output will display with empty data on that selected field
- if you want to use shortcut of ->groupby( ) to be same as all fields in ->select("field1 as fl1","field2") you can do shortcut by add one operator'$selected' into ->groupby('$selected') also auto remove as operator

      $users =  CompanyModel::collection("users")
                              ->select( "users.username as uname","services.sid as service_id" )
                              ->leftjoin("services","users.services_id","services.sid")
                              ->where( "users.username" ,"=" , "supachai")
                              ->get() ; 

     
      $users =  CompanyModel::collection('products')
                                        ->select('products.id as prod_id ','products.name','products_type.description_th','products_group.description')
                                        ->leftjoin('products_type','products.type_id','products_type.type_id')
                                        ->leftjoin('products_group','products.type_groupid','products_group.type_groupid')
                                        ->where("products.name",'like',"%phone%")
                                        ->orwhere("products.id",'>',400)
                                        ->andwhere("products.description",'like','%the%')
                                        ->groupby('products.id','products.name','products_type.description_th','products_group.description')
                                        ->orderby('products.name','asc')
                                        ->limit(10,2)
                                        ->get();

                                        ->get();

Getgroup
- Function to support side menu or dropdown menu
- request join two table

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Shopping ;

class Tester extends Controller
{
public function index() {
$test = Shopping::collection('products_group')->select('products_group.cat_id as pgid','products_group.description as gdesc','productstype.type_id as tid','products_type.description as type_desc_en')
            ->where('products_type.type_id','!=',null)
            ->leftjoin('products_type','products_group.cat_id','products_type.type_groupid')
            ->orderby('products_group.description','ASC')
            ->groupby('$selected')
            ->getgroup() ;       
    return view('test')->with('test',$test) ;  
     }
}

On Laravel blade views file test.blode.php do getgroup() same as below :

<!DOCTYPE html>
<html">

   <body>
       <h2>==test list by group==</h2>

       @foreach( $test as  $key => $value )
         
          {{$key}} => 
          group id {{  $value['gid']}} : 
                   {{  $value['pdesc']   }}  <br> 

           @foreach($value['products_type'] as  $value )  
                     --------- >>>>  type ID {{ $value['tid']}}  : 
                                     type descripton {{ $value['typeDesc_en']}}
                                     <br>
           @endforeach 
     
       @endforeach  
   </body>
</html>


// Display outcome on browser example :

Paginate
- pagination are displays data and page breakedown with data perge
- paginate going to don't care function limit() if you have added into order command
- Output of data will is in property ->items it also show below
- Output of pages number linkdata as ->link and drawing of html code by use method ->link()
- switch to page 2 using as example : http://127.0.0.1/?page=2


        $users =  CompanyModel::collection("users")
                                ->select( "users.username as u_name" , "users.password as pwd" , "address.city_name as live " )
                                ->leftjoin("services","users.city_id","address.city_id")
                                ->where( "users.username" ,"!=" , "supachai")
                                ->groupby("users.username" , "users.password" ,"address.city_id" )
                                ->orderby("users.username")
                                ->limit(4,4)   // @@ if do pagination will don't care the limit function 
                                               // don't you need to add limit() in process line the module will ignore 
                                ->paginate(10); 
         
        // Laravel view example //
         return view("usermanage" )->with('users',$users)

insert via Controller
- insert prepare code example below
- $fillable had removed replace with $schema and fillable will run behind $schema
- once collectaion and field data isn't in schema member insert will reject and has error
- find below example to use function getModifySequence() for auto increase number was bild-in this function you have to create schema to prepare on Model file then set 'AutoInc' => true , 'AutoIncStartwith' => 101, with


        $prepairinsertServices["username"] =  $request->input('username') ;
        $prepairinsertServices["email"] =  $request->input('email') ;
        $prepairinsertServices["first_name"] =  $request->input('first_name') ;
        $prepairinsertServices["last_name"] =  $request->input('last_name') ;
        $prepairinsertServices["password"] =  $request->input('psswd') ;
        $prepairinsertServices["plan"] =  $request->input('radioplan') ;
        $prepairinsertServices["services"] = [   ] ;
         // Get data from Check box 
         if ( null != $request->input('service-ecom') ) 
           array_push ( $prepairinsertServices["services"] ,[ "service-ecom" ,  $request->input('service-ecom') ])  ; 
         if (  null != $request->input('service-chat') )
            array_push ( $prepairinsertServices['services'], ["service-chat", $request->input('service-chat')]);
         if (  null != $request->input('service-email') )
            array_push ( $prepairinsertServices['services'],["service-email" , $request->input('service-emai)') ]);

       $prepairinsertServices["server-req-time"] = $_SERVER['REQUEST_TIME'] ; 

       $resultInsert =  UserModel::insert( $prepairinsertServices ) ;   // using default $collection in model
       $resultInsertOtherone = UserModel::database()->collection("services")
                                              ->insert(['sid'=> UserModel::database()->collection("services")->getModifySequence('sid') ,

                                                      'description'=>'VIP sevice top level'
                                                      ]) ; 
        
      // Handle insert error !
      if ( $resultInsert[0] == 0 ) {
            return redirect()->back() ->with('alert', $resultInsert[1] );
      }else { sleep(1) ;  }

      $users =  UserModel::all()  ; 
      
        return view('usermanage',compact('users')  ) ; 
    }

Update
- to prevent update field put in schema idcard => [ 'UpdateProtected'=>true ]
- update can be many style do you need to see examples below

$updateResult  =  ShoppingModel::collection("products")
                                                 ->where('id',"=",454)   // update mltiple style 
                                                 ->andupdate( [ "name" => "PHONE UPDATE 11.0 v3" , 'price' => 25200 ])    // Array style
                                                 ->andupdate("description","=","Iphone version Thai v3")                  // Equaly style
                                                 ->update("description_th","New iPhone 11.0 v3th ") ;                     // Two values style

$updateResult  =  ShoppingModel::collection("products")
                                                 ->where('id',"=",454) 
                                                 ->update( [ "description_th" => "New iPhone 11.0 v3th " ]) ;  // Array style
                                                 


$updateResult  =  ShoppingModel::collection("products")
                                                 ->where('id',"=",454) 
                                                 ->update( "description_th" , "New iPhone 11.0 v3th " ) ;   // Two values style

Delete documents
- request begin with where statement

      $deleteresult =  ShoppingModel::collection("products")
                                ->where("id" ,"=",444)
                                ->andwhere("id" ,"=",442)
                                ->delete("id",">",440);
                                
     $deleteresult =  ShoppingModel::collection("products")
                                              ->delete("id","=",440);

Handle insert error in view
- add script below into your view file.blade.php

   <script>
        var msg = '{{Session::get('alert')}}';
        var exist = '{{Session::has('alert')}}';
        if(exist){
        alert(msg);
        }
   </script>
