// app.js

const { Sequelize, DataTypes } = require('sequelize');

const sequelize = new Sequelize('your_database', 'your_username', 'your_password', {
  host: 'localhost',
  dialect: 'postgres',
});

const Category = sequelize.define('Category', {
  id: {
    type: DataTypes.INTEGER,
    primaryKey: true,
    autoIncrement: true,
  },
  parent_id: {
    type: DataTypes.INTEGER,
    allowNull: true,
  },
  name: {
    type: DataTypes.STRING,
    allowNull: false,
  },
  slug: {
    type: DataTypes.STRING,
    allowNull: false,
  },
});

// Retrieve category and its hierarchy in desired order as an object
async function getCategoryWithHierarchy(categoryId) {
  try {
    const category = await Category.findOne({ where: { id: categoryId } });
    if (!category) {
      console.log('Category not found.');
      return null;
    }

    const hierarchy = await getCategoryHierarchy(category);

    console.log('Category hierarchy in desired order as object:', hierarchy);
    return hierarchy;
  } catch (error) {
    console.error('Error retrieving category hierarchy:', error);
  }
}

// Recursive function to get category hierarchy in desired order as an object
async function getCategoryHierarchy(category) {
  const hierarchy = {
    id: category.id,
    parent_id: category.parent_id,
    name: category.name,
    slug: category.slug,
    children: []
  };

  if (category.parent_id !== null) {
    const parentCategory = await Category.findOne({ where: { id: category.parent_id } });
    hierarchy.parent = await getCategoryHierarchy(parentCategory);
  }

  const childCategories = await Category.findAll({ where: { parent_id: category.id } });
  for (const childCategory of childCategories) {
    hierarchy.children.push(await getCategoryHierarchy(childCategory));
  }

  return hierarchy;
}

// Example usage with category ID 9 (Non-Fiction)
getCategoryWithHierarchy(9);
