Most SaaS ideas fail before launch, not because they’re bad, but because the founder got bored building auth and billing.

You can use an infinite range in `case/when` to express "N or more" in a clean, readable way! 🤩

In Rails 8, adding a `!` to a type automatically makes the column non-nullable.

These small additions are what make Rails great! 💚

@RubyCademy rails 8 launchkit with agents.md so coding agents actually understand the boring stuff

[RubyCademy @RubyCademy]

NOBODY CODES ANYMORE.

So I built LaunchKit for the agents too!

Rails 8, all the boring stuff already built, full documentation, and an AGENTS.md that helps your coding agent understand the entire codebase.

In Rails 8, you can now access your notes directly in the browser by visiting `GET /rails/info/notes`!

Small details like this are why we love @rails! 💚

Rails has a `halted_callback_hook` that fires whenever a before_* callback halts. 🤩

Super handy for debugging and logging!

Two Rails 8 defaults that don't compose.

rate_limit counts in your cache store. Solid Cache increments under SELECT ... FOR UPDATE, which locks nothing when there's no row yet.

First hit from a new IP, two at once, both write 1. A limit of 10 admits 11.

Rails 7.1 added a neat little upgrade to rails routes --expanded: Source Locations! 💚

Now you can instantly see exactly where each route is defined in your codebase.

Ruby makes it so easy to keep user input within a safe range using `clamp()`! 💚

Perfect for forcing a value between MIN and MAX without extra ifs.

Rails 8 added `except_on:` for validations! 🤩

A clean way to say "always validate, except in this context."

It is simpler than `if:` or `unless:` and perfect for drafts, multi-step forms, or any workflow where some fields can be missing!

🔗 https://t.co/x8zss0BouE

[RubyCademy @RubyCademy]

Great question! 💚

Yep, it composes with custom contexts too.

`except_on:` accepts a symbol or an array of contexts, just like `on:`.

So you can do `except_on: [:draft, :some_custom_context]`.

Conceptually, it’s the inverse of `on:`: the validation runs in every context except the ones you explicitly exclude.

That’s what makes it nice for draft workflows.

Hope this helps! 🙏
