import prisma from "../../prisma/client";

/**
 * Getting all posts
 */

    try {
        //get all posts
        const posts = await prisma.post.findMany({ orderBy: { id: 'desc' } });

        //return response json
        return {
            success: true,
            message: "List Data Posts!",
            data: posts,
        };
    } catch (e: unknown) {
        console.error(`Error getting posts: ${e}`);
    }
}

/**
 * Creating a post
 */
export async function createPost(options: { title: string; content: string }) {
    try {

        //get title and content
        const { title, content } = options;

        //create data post
        const post = await prisma.post.create({
            data: {
                title: title,
                content: content,
            },
        });

        //return response json
        return {
            success: true,
            message: "Post Created Successfully!",
            data: post,
        }
    } catch (e: unknown) {
        console.error(`Error creating post: ${e}`);
    }
}

/**
 * Getting a post by ID
 */
export async function getPostById(id: string) {
    try {

        // Konversi tipe id menjadi number
        const postId = parseInt(id);

        //get post by id
        const post = await prisma.post.findUnique({
            where: { id: postId },
        });

        //if post not found
        if (!post) {
            return {
                sucess: true,
                message: "Detail Data Post Not Found!",
                data: null,
            }
        }

        //return response json
        return {
            success: true,
            message: `Detail Data Post By ID : ${id}`,
            data: post,
        }
    } catch (e: unknown) {
        console.error(`Error finding post: ${e}`);
    }
}

/**
 * Updating a post
 */
export async function updatePost(id: string, options: { title?: string; content?: string }) {
    try {

        // Konversi tipe id menjadi number
        const postId = parseInt(id);

        //get title and content
        const { title, content } = options;

        //update post with prisma
        const post = await prisma.post.update({
            where: { id: postId },
            data: {
                ...(title ? { title } : {}),
                ...(content ? { content } : {}),
            },
        });

        //return response json
        return {
            success: true,
            message: "Post Updated Successfully!",
            data: post,
        }
    } catch (e: unknown) {
        console.error(`Error updating post: ${e}`);

  //route get post by id
  .get('/:id', ({params: { id }}) => getPostById(id))

  //route update post
  .patch('/:id', ({params: { id }, body}) => updatePost(id, body as { title?: string; content?: string }), {
    body: t.Object({
      title: t.String({
        minLength: 3,
