• Create project table with model and migration

  // Create project model with migration 
  php artisan make:model Project --migration
  
  // Add columns to project migration file under - database\migrations\<2021_04_21_125826>_create_projects_table.php
  Schema::create('projects', function (Blueprint $table) {
      $table->id();
      $table->string('name');
      $table->timestamps();
  });
  
  // Run migrate command to create table structure
  php artisan migrate
  

  First you have to run artisan command with php artisan make:model Project --migration. This command will create a model and migration for your table structure. After that you can add columns to the migration file and run the php artisan migrate command.

• Create pivot table in laravel with multiple columns

  --PATH database\migrations\<yourmigrationfile>.php

  //Migration command to create migration file
  php artisan make:migration create_project_user_table --create=project_user
  
  //Migration file code under - database\migrations\<yourmigrationfile>.php
  public function up(){
      Schema::create('project_user', function (Blueprint $table) {
          $table->foreignId('project_id')->constrained();
          $table->foreignId('user_id')->constrained();
          $table->boolean('is_manager')->default(false);
          $table->timestamps();
      });
  }
  

  You can add multiple columns in the laravel pivot table using migration. This code snippet adds is_manager columns in the pivot table with default value false and adds created_at and updated_at fields using timestamps method.
