List of columns 


$table->id(); // increment value
$table->string('title')->comment('this is blog title');
$table->string('slug')->unique();
$table->text('short_desc');
$table->longText('description');

$table->timestamps();
$table->foreign('created_by')->references('id')->on('users'); // introducing foreign key
$table->unsignedBigInteger('user_id'); //?
$table->decimal('latitude', 9, 6)->nullable(true);

// Let's say you want starting value from 1000
$table->id()->from(1000); // increment value start from 1000

->nullable(true) // boolean value

->default(your value);

//We can apply unique()

$table->string('slug')->unique();

or
$table->string('slug');
$table->->unique('slug');

$table->unique(['slug','your_column_name']);

//if you want apply uniqueness on two columns or more 
$table->unique(['columnName1', 'columnName2']);

//Creating UUID:
 $table->uuid('user_id')->primary();

//Creating relationship with uuid (relation another table)

//To setup default DB timestamp

        DB::table('roles_modules')->insert($data);
    }

Laravel has seeder feature, To insert some master data in database while migrating. 

php artisan make:seeder UserSeeder

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Str;
use Illuminate\Support\Facades\Hash;
use Carbon\Carbon;

class UserSeeder extends Seeder
{
    /**
     * Run the database seeds.
     */
    public function run(): void
    {
        $users = [
            [
                'user_id' => '4bace869-9bc0-424c-9292-111dac5b7ee7',
                'first_name' => 'Admin',
                'middle_name' => 'D',
                'last_name' => 'Doe',
                'email' => 'admin@mailinator.com',
                'password' => Hash::make('India@123'),
                'role_id' => 1,
                'created_at' => now(),
                'updated_at' => now(),
            ],
            [
                'user_id' => Str::uuid(),
                'first_name' => 'Jane',
                'middle_name' => 'E',
                'last_name' => 'Smith',
                'email' => 'sid@mailinator.com',
                'password' => Hash::make('India@123'),
                'role_id' => 2,
                'created_at' => now(),
                'updated_at' => now(),
            ],
            [
                'user_id' => Str::uuid(),
                'first_name' => 'Alice',
                'middle_name' => 'F',
                'last_name' => 'Johnson',
                'email' => 'alice.johnson@example.com',
                'password' => Hash::make('password'),
                'role_id' => 1,
                'created_at' => now(),
                'updated_at' => now(),
            ],
            // Add more users as needed
        ];

        // Insert users and create profiles
        foreach ($users as $user) {
            DB::table('users')->insert($user);

            $profileData = [
                'user_id' => $user['user_id'],
                'kyc_status' => 'Pending',
                'dob' => Carbon::now()->format('Y-m-d'), // Adjust as needed
                'account_type' => $user['role_id'] === 1 ? 'Corporate' : ($user['role_id'] === 2 ? 'Personal' : 'Personal'),
                'sex' => 'Male', // Adjust as needed
                'phone_no' => '1234567890', // Adjust as needed
                'country_id' => 1, // Adjust as needed
            ];

            if ($profileData['account_type'] === 'Corporate') {
                $profileData['company'] = 'Example Corp';
                $profileData['company_sector'] = 'Technology';
                $profileData['company_address'] = '1234 Example St';
            }

            DB::table('profiles')->insert($profileData);
        }
    }
}



After this you need to update userSeeder on databaseSeeder.php

<?php

namespace Database\Seeders;

use App\Models\User;
// use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     */
    public function run(): void
    {
        // User::factory(10)->create();

        // User::factory()->create([
        //     'name' => 'Test User',
        //     'email' => 'test@example.com',
        // ]);

        // Call the UserSeeder
        $this->call(UserSeeder::class);       
    }
}


and then finally run migrate

php artisan migrate:fresh --seed

Data Types in Python

Data Types  In C# or Java, You need to declare a variable specify them integer, string, and decimal. But in Python no need to specify. We can declare variables like Example: C# or Java int age = 28; string Name = "Siddhu"; Example: Python age = 28 Name = "Siddhu" So, you don't need to declare variable types in python. This is an advantage in Python, But still have few Disadvantages too. Example: In my Python function def add_numbers(x,y): print(x+y) add_numbers(20,50) //Output: 70 add_numbers(20,"Something") //Error:"Traceback (most recent call last): File "C:/Users/siddhartha.e/PycharmProjects/siddhu-py/my1stpycode.py", line 8, in add_numbers(50,"Something") File "C:/Users/siddhartha.e/PycharmProjects/siddhu-py/my1stpycode.py", line 4, in add_numbers print(a + b) TypeError: unsupported operand type(s) for +: 'int' and 'str'" ...

Database and Migrations

Database and Migrations You can config Database in the .env file. By default, Laravel has MySQL configuration. For example, I configured my details DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=Laravel_tutorials DB_USERNAME=root DB_PASSWORD= So how it connects the database, In your root folder config/database.php file will read the .env file configuration. Migrations: Migrations are most likely a version control for your database. Advantages You can easily allow your team to modify database schema and share to everyone in the application No headache to add a new column in the database manually. This migration will help all teammates into one path. Now check with artisan command php artisan migrate php artisan migrate This command will create basic users,password_resets and migrations tables. Here migrations table will track of all migrates You can undo previous migration using rollback command php artisan ...

Laravel form validations

 Laravel Validations: List of types "first_name" => 'required|alpha:ascii|min:3|max:100',// alpha:ascii (only accepts a-z) "middle_name" => 'string', "last_name" => 'required|string', "email" => 'required|email|unique:users,email', "password" => 'required|string|confirmed', "sex" => 'required|string', "phone_no" => 'required|string', "account_type" => 'required|string', "dob" => 'required|date_format:d-m-Y', // date with format "nationality" => 'required|string', "company" => 'required|string', "company_sector" => 'required|string', "company_address" => 'required|string' "bank_account_no" => 'required|min_digits:3|max_digits:5', "role" => 'required|in:admin,editor,viewer', ...
