Laravel: Migrations

After you have created a migration and still want to add a new field, you can proceed as follows:

Run the command php artisan make:migration alter_table_model

This command will create a new migration file in the database/migration folder.

You should add in the up method the following line of code:

Schema::table('nome da tabela',function($t){
   $t->string('novo_campo')->nullable();
});

In the down method:

Schema::table('nome da tabela',function($t){
       $t->dropColumn('novo_campo');
    });

Then just execute the command php artisan migrate

You will now notice that migration has created a new field in the reported table.

If you want to create a new field without having to create a new migration, you can run php artisan migrate:rollback to return the database table to the previous state, edit the migration file, and re-execute php artisan migrate for new changes.

Note: When executing the rollback the method called is down . So you should always create this method to revert what was created in the up method.

David, what's up?

The migration also supports schema changes, not just creation.

A great library to make this easy is Laravel Generators

Command example:

php artisan generate:migration add_user_id_to_posts_table

It will create migration for you by adding the user_id field to posts table. Show né?

This library is an immense facility, it generates all scaffold.

Needing a touch!

I have a question about Laravel's Migrations and I believe they can help me.

1 - I created a model with migration by %code%

2 - In addition to increments and timestamps I added one more field to the migration: %code%

3 - I ran the command %code%

My question is, after I ran the php artisan migrate the table was created in the database. And if by chance I need to add another column in the table in the bank, how should I proceed in relation to the respective laravel migration? Should I make direct in the bank or is there a migration command?

only use the php artisan migrate:. Refresh after you change your migrate file

It will make a rollback of your tables, and will recreate them.
