[FIXED] Not null violation: 7 ERROR: null value in column - Laravel 5.8

Issue

I don't understand this, I alter my table to add these columns

Schema::table('clusters', function($table)
{

    $table->string('ssaEnabled',1)->default('0');
    $table->string('ssaBackendUrl')->default(NULL);
    $table->string('ssaPortalApiUrl')->default(NULL);

});

in my store() I have this

$cluster->ssaEnabled            = Input::get('ssaEnabled','0');
$cluster->ssaBackendUrl         = Input::get('ssaBackendUrl','');
$cluster->ssaPortalApiUrl       = Input::get('ssaPortalApiUrl','');

$cluster->save();

I kept getting

prod.ERROR: SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column "ssaBackendUrl" violates not-null constraint

Why ??

1. I set it to default null already
2. I also add a backup value in my Input::get() in the 2nd param as an empty string

Any hints?

How can I stop that ?

Solution

• Create a new migration

php artisan make:migration add_nullable_to_ssaBackendUrl_column_on_clusters_table --table=clusters

Updating Column Attributes

The change method allows you to modify the type and attributes of existing columns.

Schema::table('clusters', function($table)
{

    $table->string('ssaBackendUrl')->nullable()->change();

});

• Run the migration

php artisan migrate
