Are you tired of sluggish ActiveRecord queries? Does the N+1 query problem frustrate you? If you’re nodding your head (or just grunting in agreement), you’re in the right place! OccamsRecord is a game-changing query library designed to dramatically enhance the performance of your ActiveRecord applications. In this guide, we’ll explore how to seamlessly integrate OccamsRecord into your app, along with troubleshooting tips to help you along the way.

Understanding OccamsRecord: The Performance Booster

Before diving into the how-to, let’s get a grasp of what OccamsRecord brings to the table. Picture it as a turbocharger for your car; without it, your vehicle moves, but not as swiftly as it could. OccamsRecord comes with many benefits, including:

• Performance Gains: Up to 5x faster than standard ActiveRecord queries and uses only 1/3rd of the memory.
• Eager Loading: Customized SQL queries to eagerly load your associations, eliminating the dreaded N+1 query problem.
• Advanced Query Capabilities: Includes use of raw SQL queries with all the advantages of eager loading.

Integrating OccamsRecord into Your App

Ready to give your ActiveRecord app a much-needed performance boost? Follow these steps to integrate OccamsRecord:

Step 1: Install the Gem

First, you need to install the OccamsRecord gem. To add it to your project, open your Gemfile and include the following line:

gem 'occams-record'

Then run:

bundle install

Step 2: Build Your Queries

Use ActiveRecord’s powerful query builder and pass them off to OccamsRecord for enhanced performance:

q = Order.completed.where(order_date: 30.days.ago).order(order_date: :desc)

orders = OccamsRecord.query(q).run

Step 3: Eager Loading

Eager loading is essential to prevent N+1 queries. Here’s how to do it:

orders = OccamsRecord.query(q)
    .eager_load(:customer)
    .eager_load(:line_items)
    .eager_load(:product)
    .run

Just remember, if you forget to eager load an association, you’ll get an error. Think of OccamsRecord as your strict school principal ensuring you do your homework (eager load your associations) or face consequences!

Advanced Features for Power Users

Once you’re comfortable with the basics, you can explore advanced querying options, such as raw SQL queries and information adjustments using eager_load_many. This allows you to become a SQL wizard, performing magic with your data.

products_with_orders = OccamsRecord.query(Product.all)
    .eager_load_many(:customers, :id => :product_id, 
    "SELECT DISTINCT product_id, customers.* 
    FROM line_items INNER JOIN orders ON line_items.order_id = orders.id 
    INNER JOIN customers ON orders.customer_id = customers.id 
    WHERE line_items.product_id IN (%ids)").run

Troubleshooting Common Issues

If you encounter issues while using OccamsRecord, here are some troubleshooting ideas:

• MissingEagerLoadError: This occurs when trying to access an association not eager loaded. Make sure to include all necessary associations.
• Performance Not Improving: Check your query structures and ensure you are eagerly loading where needed.
• Raw SQL Queries Not Returning Expected Results: Double-check your SQL syntax and bindings.
