使用Postgres在Laravel 5.5 Migrations中定义字段

Question

Working with Laravel 5.5 Migrations with Postgres :

1) Defining field as :

$table->enum('is_applied', ['Y', 'N']) ->comment('Y => is_applied, N=> Is not applied');

I see in generated table next:

is_applied varchar(255) NOT NULL,
    CONSTRAINT cs_tmp_csvps_is_applied_check CHECK (((is_applied)::text = ANY ((ARRAY['Y'::character varying, 'N'::character varying])::text[]))),

actually I would like to get sql I used in Postgres with type:

CREATE TYPE type_cms_item_content_type AS ENUM (
    'P',
    'M',
    'H'
);

    content_type type_cms_item_content_type NOT NULL DEFAULT 'P'::type_cms_item_content_type,

Is it possible?

2) Defining field as :

$table->timestamps();

I have 2 fields created created_at and updated_at . As I need to create only created_at I could write :



$table->dateTime('created_at');

But is there is a way to set default time on server, like :

created_at timestamp NOT NULL DEFAULT now(),

?

Thanks!

Answer 1

You can do:

$table->timestamp('created_at')->useCurrent();

for the timestamps issue. If you really want exact sql changes you can always do a raw sql statement in a migration:

Schema::table('content_type', function(Blueprint $table){
    $sql = 'CREATE TYPE type_cms_item_content_type AS ENUM (
    `P`,
    `M`,
    `H`
);

    content_type type_cms_item_content_type NOT NULL DEFAULT `P`::type_cms_item_content_type';
    DB::connection()->getPdo()->exec($sql);
});

1) Defining field as:

$table->enum('is_applied', ['Y', 'N']) ->comment('Y => is_applied, N=> Is not applied');

The method comment() it's only for MySQL, in the Migrations on Laravel.

2) Defining field as:

The Answer of @alex-harris is a gob option

$table->timestamp('created_at')->useCurrent();
