Incorrect Syntax in DBML Export for dbdiagram.io & Incorrect File Extension

[jawahar2003]

Description

When converting a Laravel database schema to DBML format using php artisan dbml:parse, two issues occur:

Incorrect Syntax in Default Values

• The generated DBML contains:

  id bigint [not null, default: 'nextval('users_id_seq'::regclass)']
  

• This causes errors in dbdiagram.io due to nested single quotes.

Fix:

• Using double quotes resolves the issue:

  id bigint [not null, default: "nextval('users_id_seq'::regclass)"]
  

Incorrect File Extension

• The exported file is saved as .txt instead of .dbml.
• Expected behavior: It should be .dbml for compatibility with DBML tools.
