Laravel - Creating Table Migrations

1) Laravel has its own way of creating data tables and performing rollback. This is called Migration.

2) Migration works is done via PHP CLI and artisan script command

3) Install the Migration table to the laraveldb.

3a) Run Command Window. Change directory to {laravel root}.

3b) Ensure that you have registered PHP execution path in Windows Environment. If you are not sure, follow this tutorial.

3c) Run Install command.

3a) Type php artisan migrate:install

3b) Type php artisan migrate:make create_users_table

>php artisan migrate:install
Migration table created successfully.

>php artisan migrate:make create_users_table
Great! New migration created!

4) Edit the table migration settings.

4a) Open {laravel root}\application\migrations\2013_02_02_192721_create_users_table.php



4b) Edit as follows:

<?php

class Create_Users_Table {

 /**
  * Make changes to the database.
  *
  * @return void
  */
 public function up()
 {
  Schema::create('users', function($table)
  {
  $table->increments('id');
  $table->string('email');
  $table->string('real_name');
  $table->string('password');
  $table->timestamps();
         });
 }

 /**
  * Revert the changes to the database.
  *
  * @return void
  */
 public function down()
 {
  Schema::drop('users');
 }

}

5) Run migration
(a table migration file is created)

>php artisan migrate
Migrated: application/2013_02_02_192721_create_users_table

6) Check the newly created table in laraveldb
(the users table has been created)
(the users table properties is according to the definition in table migration file)

>mysql -h localhost -u laraveladmin -p

(the users table has been dropped)

mysql> show tables;
+---------------------+

+---------------------+
| laravel_migrations  |
+---------------------+

mysql>

9) Run migration again (Step 5)

>php artisan migrate
