If you're working with database extensions, it can be helpful to exclude tables added by your extensions from your schema file. Keep it free from clutter! 🧹

The example shows SQLite and Spatialite, should work with any database and extension though.

#ruby #rubyonrails

TIL that the Ruby interpreter won't load a file with a shebang line that doesn't contain "ruby"

This fails:
#!/bin/gem-language
#!some-wrapper-for-ruuuuby

But this is fine:
#!aaarubyeee
#!/random/nonexistent/directory/ruby

I use SVGs a lot - and so should you! They're great.

Here's how you easily inline them. No need for any additional gems. Twelve lines of helper method are all you need 👌

Ruby 3.5 Feature: Namespace on read

https://bugs.ruby-lang.org/issues/21311

#ruby

If you're creating a reasonably complex Thor CLI, you'll likely want to reuse common method options. Here's a simple way to do that.

#ruby #rubyonrails

TIL: You can pass modifies to generators using curly braces. For example, create a decimal column with precision and scale 🤩

#ruby #rubyonrails

I got to pull out a nice RSpec trick today - using compound expectations.

I wanted to check that a method was called with a (rather large) string that had a few different substrings in it.

expect(instance).to receive(:method).with(
a_string_including("thing 1") &
a_string_including(obj.message) &
a_string_including("asdfasdfgasd")
)

The trick here is combining matchers with &

There's other ways you might do this, but the test output is really nice this way.

#ruby #rspec

TIL; defining a route in Rails 8 automatically defines an empty action that renders the matching view.

No more boilerplate generating empty method in my controller such as

def show; end

#ruby #rails

TIL: graphql-ruby supports async data loaders out of the box. A must have if you have fields that do network requests when resolved.

#rubyonrails #graphql

TIL there's an ISO8601 notation for time *intervals* too… 🧐

#ruby #rails

Good progress writing a #ruby SDK for Datastar. This is a simple Rack app streaming UI updates to the browser from two different threads.

@joeldrapper I think I'm in this scenario (with some more overhead) because I have plain SLIM content that are aggregated before or after the view_template.

Thanks a lot for your explanations, I now gets why my helpers are being call in the before_template using vanish.

I'll keep digging, using your example as documentation \o/

I need to migrate an "old" framework based on #phlex . I'm working on adding the deferred rendering to our existing stack; and can't wrap my head around what that `vanish(&)` thing do.

So many unexpected behaviours, if only we had time to do this more thoughtfully at first.

Are you an engineer and want to make a difference?

3. Support Mastodon. It's the only billionaire-proof social media.

RuboCop 1.71 is out! Lots of small improvement in this release (see for all the details https://github.com/rubocop/rubocop/releases/tag/v1.71.0), but I'd like to highlight that supposedly now RuboCop handles properly safe navigation in every single cop!

It only took us 8 years to get there! 😅

Actually playing with #phlex and #literal in #ruby on #rails and it feels awesome. Rock solid gems !
