    Lazy loading associations for the ActiveRecord models

    Attentive reader could notice that in every described case, it was a requirement to explicitly list data that we want to preload for a group of users. Gladly, there is a simple solution! ArLazyPreload will make N+1 disappear just by enabling it. As soon as you need to load association for any record, it will load it once for all records that were fetched along this one. And it works with ActiveRecord and N1Loader perfectly!

  • counter_culture

    Turbo-charged counter caches for your Rails app.

    It's worth mentioning counter_culture alternative that has many features compared with the built-in counter_cache

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  • n1_loader

    Loader to solve N+1 issues for good. Highly recommended for GraphQL API.

    Unfortunately, such associations are not possible to preload with includes. Gladly, there is a solution with N1Loader.

  • DatabaseConsistency

    The tool to avoid various issues due to inconsistencies and inefficiencies between a database schema and application models.

    Described issues may be found with DatabaseConsistency.

  • Goldiloader

    Just the right amount of Rails eager loading

    Thank you for sharing this with me! It seems that https://github.com/salsify/goldiloader gem does the same as https://github.com/DmitryTsepelev/ar_lazy_preload. It would be great to compare both solutions.
