Rails 7 adds in_order_of for ActiveRecord::QueryMethods and Enumerable

Quite often in our Rails application, we need to retrieve records sorted in a specific order. For example, in an e-commerce application, we want to retrieve the customer orders in the order of "Completed, Cancelled, In Transit, Pending" statuses. The way to do it is to write an explicit SQL query. Starting Rails 7, this can be achieved simply with the help of the in_order_of method for ActiveRecord::QueryMethods and Enumerable. This article explains how we can use the in_order_of method to sort data in Rails 7. 1. ActiveRecord::QueryMethods#in_order_ofConsider we have a

Rails 7 auto detects inverse_of for scoped associations

Rails framework is famous for developers' happiness and making things simpler due to its magic, provided developers follow proper conventions. To extend this magic and to make things simple further, Rails 7 has introduced a change with this PR after which, inverse_of would be inferred automatically for model associations having scopes. In this article, we'll dive into understanding it with examples. Let's say we have a Project model with many assigned tasks. # app/models/project.rb class Project < ActiveRecord::Base has_many :tasks, -> { assigned } end # app/models/task.rb class Task < ActiveRecord::Base belongs_to

Rails 7 adds new options to upsert_all

We often come across use cases in a Rails application where we need to create, update, or delete records in bulk. Most ORMs naively update or insert each record individually by executing N+1 database queries. To address this problem, Rails 6 added the upsert_all method that provides a faster way to update and insert a large number of records. upsert_all uses a single SQL INSERT statement for updating/inserting the records. And it does so without instantiating any models. Nor does it trigger any Active Record callbacks or validations ! How upsert_all works? If we check the
