I gave a talk at Rails World 2023 in Amsterdam on Powerful Rails Features You Might Not Know. If all you've got is a hammer, everything looks like a nail. In tech, there is a constant stream of new features being added every day. Keeping up with the latest Ruby on Rails functionality can help you and your team be far more productive than you might normally be. In this talk, we walk through a bunch of lesser known or easy to miss features in Ruby on Rails that you can use to improve your skills ..read more

Here at GoRails, we are running ActiveAdmin to power our administration area and we recently upgraded the version which we were running to version 3.0.0. The ActiveAdmin engine has a dependency on Ransack and along with upgrading to the latest version of ActiveAdmin that brought along an upgrade of Ransack to version 4.0.0. Going up a major version usually introduces breaking changes and sure enough this was our experience. As noted in the Ransack CHANGELOG for the version 4.0.0 release there is indeed a breaking change introduced: Require explicit allowlisting of attributes and associations ..read more

OmniAuth provides some tooling for mocking OAuth requests in your test suite. This is handy because your tests don't have to redirect to a production OAuth provider like Twitter, authenticate with real credentials, and then handle the response. Instead, you can set test mode in OmniAuth and then add a mock OAuth provider. This will allow your tests to skip the production OAuth process and simulate it in your test environment. One problem is testing additional params you might pass to OmniAuth. For testing, you normally just request the callback URL for the mock request. If you test only with t ..read more

Have you seen the following error? You have already activated uri 0.10.0, but your Gemfile requires uri 0.12.0.

(Gem::LoadError) You have already activated strscan 3.0.1, but your Gemfile requires strscan 3.0.2. Since strscan is a default gem, you can either remove your dependency on it or try updating to a newer version of bundler that supports strscan as a default gem.

If you're building a Rubygem that integrates with Rails and ActiveRecord, you'll probably want to test against multiple databases. This is pretty easy to setup for CI where you can run multiple databases in Docker containers with different steps, but what about local development? The DATABASE_URL is typically used for setting the production database for your Rails app. Hatchbox, Heroku, Render, etc all will set this environment variable for Rails to pick up and use the correct database. You might not realize that the DATABASE_URL can also be used for other things like testing! Instead of runni ..read more

ActionText supports custom attachments using Signed Global IDs. We can use this to embed any database record in Rails such as @mentions for users. For HTML, Rails will use the to_partial_path to render the HTML template for the attachment. For a user, this would be app/views/users/_user.html.erb. With Plain Text output, Rails will default to the caption specified on the attachable. Typically, this is nil because we don't need a caption for an @mention. By defining the attachable_plain_text_representation method, we can specify the default value for the plain text ActionText output. class User ..read more

If you want to keep your code simple and/or reuse a block of code in multiple files, then you can store that code in an html.erb file called a partial. Create partial ? Go to app > views. Create a folder called shared.
