from flask import Flask

# Adjust the DATABASE_URL format for SQLAlchemy compatibility
database_url = os.getenv("DATABASE_URL", "")
if database_url.startswith("postgres://"):
    database_url = database_url.replace("postgres://", "postgresql+psycopg2://")

app.config["SQLALCHEMY_DATABASE_URI"] = database_url

• This code retrieves the DATABASE_URL from the environment.
• If DATABASE_URL starts with postgres://, it replaces it with postgresql+psycopg2://.
• The db instance is initialized with SQLAlchemy(app) for use with SQLAlchemy ORM.
• The replacement of "postgres://" with "postgresql+psycopg2://" is necessary because of a compatibility issue between the URI format provided by Heroku and the URI format expected by SQLAlchemy.

You can loop through all posts, delete each post, and then remove any associated media files (attachments). Here's a complete script to achieve this:

<?php
// Load WordPress environment
require_once('/path/to/your/wp-load.php');

// Get all posts (any post type)
$args = array(
    'post_type'      => 'any', // 'any' retrieves all post types (posts, pages, custom post types)
    'post_status'    => 'any', // 'any' retrieves all post statuses
    'posts_per_page' => -1,    // Retrieve all posts
);

$all_posts = get_posts($args);

foreach ($all_posts as $post) {
    // Get the post ID
    $post_id = $post->ID;

    // Check if the post has attachments (media files)
    $attachments = get_attached_media('', $post_id);

    // Delete each attachment associated with the post
    foreach ($attachments as $attachment) {
        $attachment_id = $attachment->ID;
        // This deletes the file from the uploads directory and the database record
        wp_delete_attachment($attachment_id, true);
    }

    // Delete the post itself
    wp_delete_post($post_id, true); // true = force delete, bypass trash
}

echo 'All posts and their uploads have been deleted.';
