Firebase realtime database එකකින් data ගන්නෙ කොහොමද අපිට custom dashboard එහෙක පෙන්නන්න පුලුවන් විදිහට.. charts වලට එහෙම.

What is the best javascript framework to learn? What is popular in sri lanka? Ex: Codgen uses Angular for their frontend development.

Thanks bro well done

public function up()

@cody Great!

@ciaompe yh i checked. it returns the correct guard value

I have two separate logins using guards which customer & adminuser. I have checkRole middleware for adminuser login and it works perfectly. I used guest middleware (RedirectifAuthenticated) to customer login. When customer login check with Auth::guard($guard)->check() it always returns false. But Auth::guard('customer')->attempt returns true. I can't find a solution.

here is the login controller for customer

class LoginController extends Controller
{

    use AuthenticatesUsers;

    public function __construct()
    {
       $this->middleware('guest:customer')->except('customerlogout');
    }

    //login the customer
    public function customerLogin(Request $request)
    {
        $email = $request->get('email');
        $password = $request->get('password');
        
        
        //Getting user inputs and authenticate the customer
        $status = Auth::guard('customer')->attempt([
            'email' => $email, 
            'password' => $password ] 
            );

        //Check login  
        if ($status) {
            //if login pass,redirect to customer account page
            return redirect()->intended('/customer_account');
            
         }else{
             //if login fail,redirect back to home page
             return redirect()->back();
         }
    }
    
    //logout the customer
    public function customerlogout(Request $request)
    {   
        Auth::guard('customer')->logout();
        $request->session()->flush();
        return redirect('/index');   
    }
}

here is the guest middleware

    public function handle($request, Closure $next, $guard = null)
    {       
        if ($guard === "customer" && Auth::guard($guard)->check()) {
            return redirect('/customer_account');
        }
        if (!Auth::guard($guard)->check()) {
            return redirect('/index');
        }
        return $next($request);
    }

Any help is appreciated, thanks!

@root any answer?

laravel framework එක හොඳට දන්න කෙනෙක් උදව් කරන්න. customers ලටයි Admin users ලටයි වෙන වෙනම guards දෙකක් හඳල තියෙන්නෙ. ඒත් attempt method එකෙන් හරියට login එක වෙලා redirect වෙන්නෙ නැ.

මේ Logincontroller එක
dd($status) එකෙනුත් false රිටන් වෙන්නෙ.

<?php

කොහොමද මේක හදාගන්නෙ. plz help!

i know about ML bro, but for my project expect a own work, without libraries or frameworks. i found a javascript library called brain.js ; it is vey easy than tensorflow.js; this problem can easily solve with it. but i wish a simple algorithm for this only with js. according to the situation i will use brain.js instead of my own algorithm.
thanks.

I want to predict the next number by analysing a array of random number sequence in javascript without libraries. How can i do this ?
Ex : array = [ 27, 35, 19 ,7 ,59, 45 ] what number is next?
