How to start using data validation in kv?

Hey fellows! I want to dive into data validation. Any experience or suggestions? Feel free to post a commented version of the repository I provided here:

import Post from '@/modules/post/model.ts'

import { setData, getData, listData, removeData } from '@/helpers/data.ts'

type PostParams = {
    blogSlug?: string
    postSlug?: string
    postInput?: Post
}

class PostRepository {
    static async createPost({ postInput, blogSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postInput?.slug as string]
        const result = await setData({ key, value: postInput })
        if (result.ok) return await getData({ key })
    }

    static async listPosts({ blogSlug }: PostParams) {
        const prefix = ['blog', blogSlug as string, 'post']
        return await listData({ prefix })
    }

    static async showPost({ blogSlug, postSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postSlug as string]
        return await getData({ key })
    }

    static async updatePost({ postInput, blogSlug, postSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postSlug as string]
        return await setData({ key, value: postInput })
    }

    static async deletePost({ blogSlug, postSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postSlug as string]
        await removeData({ key })
    }
}

export default PostRepository

import Post from '@/modules/post/model.ts'

import { setData, getData, listData, removeData } from '@/helpers/data.ts'

type PostParams = {
    blogSlug?: string
    postSlug?: string
    postInput?: Post
}

class PostRepository {
    static async createPost({ postInput, blogSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postInput?.slug as string]
        const result = await setData({ key, value: postInput })
        if (result.ok) return await getData({ key })
    }

    static async listPosts({ blogSlug }: PostParams) {
        const prefix = ['blog', blogSlug as string, 'post']
        return await listData({ prefix })
    }

    static async showPost({ blogSlug, postSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postSlug as string]
        return await getData({ key })
    }

    static async updatePost({ postInput, blogSlug, postSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postSlug as string]
        return await setData({ key, value: postInput })
    }

    static async deletePost({ blogSlug, postSlug }: PostParams) {
        const key = ['blog', blogSlug as string, 'post', postSlug as string]
        await removeData({ key })
    }
}

export default PostRepository

Thank you!

Breaking a cycle (Post > Blog > Post > Blog > ...)

Hey fellows! I stumbled into a cycle and don't know how to break it. It occurs between posts and blogs. This is the controller action:

[HttpPost("/blog/{blogSlug}/post")]
    public async Task<Post> CreatePost([FromBody] PostInput postInput, [FromRoute] string blogSlug)
    {
        User user = await _dataContext.Users.FirstAsync((u) => u.Slug == "timo");
        Blog blog = await _dataContext.Blogs.FirstAsync((b) => b.Slug == blogSlug);
        Post newPost = PostMapper.ToPost(postInput, user: user, blog: blog);
        _dataContext.Posts.Add(newPost);
        await _dataContext.SaveChangesAsync();

        return newPost;
    }

[HttpPost("/blog/{blogSlug}/post")]
    public async Task<Post> CreatePost([FromBody] PostInput postInput, [FromRoute] string blogSlug)
    {
        User user = await _dataContext.Users.FirstAsync((u) => u.Slug == "timo");
        Blog blog = await _dataContext.Blogs.FirstAsync((b) => b.Slug == blogSlug);
        Post newPost = PostMapper.ToPost(postInput, user: user, blog: blog);
        _dataContext.Posts.Add(newPost);
        await _dataContext.SaveChangesAsync();

        return newPost;
    }

How to break the cycle? Thanks.

Warning: NULL literal or a possible NULL value is being converted to a non-nullable type.

Ladies and gentlemen, I am confronted with a new type of warning, that I would like to understand. What should I do? This is the code:

    [HttpGet("/{userSlug}")]
    public async Task<User> ShowUser(string userSlug)
    {
        User user = await _dataContext.Users.FirstOrDefaultAsync((u) => u.Slug == userSlug);

        return user;
    }

    [HttpGet("/{userSlug}")]
    public async Task<User> ShowUser(string userSlug)
    {
        User user = await _dataContext.Users.FirstOrDefaultAsync((u) => u.Slug == userSlug);

        return user;
    }

This is the message: NULL literal or a possible NULL value is being converted to a non-nullable type

Hey fellows! I wonder how to set the properties for related models ... Here is my model:

public class Comment(string name, string content)
{
    public Guid Id { get; set; } = Guid.NewGuid();

    public string Name { get; set; } = name;
    public string Content { get; set; } = content;

    public DateTime CreatedAt { get; set; } = DateTime.Now;
    public DateTime UpdatedAt { get; set; } = DateTime.Now;

    public User? User { get; set; }
    public Post? Post { get; set; }
}

public class Comment(string name, string content)
{
    public Guid Id { get; set; } = Guid.NewGuid();

    public string Name { get; set; } = name;
    public string Content { get; set; } = content;

    public DateTime CreatedAt { get; set; } = DateTime.Now;
    public DateTime UpdatedAt { get; set; } = DateTime.Now;

    public User? User { get; set; }
    public Post? Post { get; set; }
}

Thank you for your help.

how to randomly display data in SwiftUI?

typical use case for flash cards... I have shelves that contain boxes that contain cards. i want to randomly select a card from a box and display its data (front) and accept user input (right or wrong) and increment card.level if user selects "right" or decrement if he/she selects "wrong", after he/she has seen the back of the card. How to approach this use case? Have a nice day, and thank you!
