Have you ever heard of the Static Model pattern? 🤩.#rubyonrails #activemodel

✨ RAILS PRO TIPS ✨. Effortlessly group validation errors by attribute with ActiveModel::Errors#group_by_attribute ✨💫. #rubyonrails #activerecord #activemodel

Rails is just too good. 💚. Define a custom ActiveModel type, register it, and boom: automatic and reusable currency normalizer! 💥 😊. #rubyonrails

Take advantage of `ActiveModel::Attribute` and the `:immutable_string` cast type to ensure your string attributes are automatically frozen ✨💫. #rubyonrails #activemodel

The #ActiveModel documentation has just been reviewed and edited and the PR is now up for community review. Fair warning: this is a lengthy guide, but if you have time and want to help, please take a look:

✨ RAILS PRO TIPS ✨. Take advantage of ActiveModel::API to implement models similar to ActiveRecord::Base ✨💫. PS: Note that ActiveModel::Model is nothing but an empty shell that includes ActiveModel::API.

This Week in Rails: An improvement to routing performance, the execution wrapper now catches all exceptions, ActiveModel type values are now mutable by default, PostgreSQL adapter improvements, and smarter query handling! Read about all these changes in this week's edition:

Did you know ActiveModel supports objects with composite primary keys? I used this to model events grouped by a few properties. Groups were a concept in my UI but not in the database. Just as easy as ActiveRecord!.

Today I used Serializers in ActiveModel for the first time. Love learning new stuff, especially when it’s getting to know the framework itself better (#rubyonrails) 🤓

Rails Introduces ActiveModel::Attributes::Normalization

Combine the power of: . ➡️ `ActiveModel::Attributes#attributes`.➡️ and `ActionView::Helpers::DebugHelper#debug`. to render readable YAML for all attributes in your object, directly in your views! 🤩. #rubyonrails #actionviews

I need to serialize an array of ActiveModel::Model instances and store them in an ActiveRecord model attribute. I made several attempts to achieve this with the `serialize` AR method, and ended up needing to write a custom coder for this use case. What do you think of this

✨ RAILS PRO TIPS ✨. Take advantage of ActiveModel::Name#human to transform model names into a more human format, using I18n ✨💫. By default, it will underscore and then humanize the class name. #rubyonrails #activemodel

Here's an easy way to enforce uniqueness within a specific scope. 🤩. For example, a lesson name can be made unique within each course. #rubyonrails #activemodel #activerecord

Yet another shorthand that makes Rails awesome! 🤩. PS: Note that ActiveModel::Model is nothing but an empty shell that includes ActiveModel::API. #rubyonrails #activemodel #activerecord

If you're using ActiveModel::Dirty in after_commit callbacks, make sure you're not saving the record multiple times in the same transaction. It'll report only the attributes that were changed before the LAST save. Or avoid using these helpers in commit callbacks.

Following @_swanson's lead, more real code Friday!. This is the registration flow for the RailsDevs referral program. I'm using ActiveModel::Model for a form - no database table needed. `valid?` ensures a checked agreement. `validates :agreement` adds an attr_accessor, too.

I love how Rails makes it effortless to humanize model names with `ActiveModel::Name#human`, converting them into a more readable format using I18n!  🤩. #rubyonrails #activemodel

Very exciting. Custom form builder to create ActiveModel backed forms for shadcn on Rails.
