Diagnosing performance problems in a production Ruby on Rails application can be deceptively complex. When constructing a new application or expanding the features of an existing one, development environments that are not subject to typical production web traffic may not make performance issues evident. In those instances, the use of some simple (and mostly free) tools can help diagnose performanc
In a previous post, I illustrated a few helpful ActiveRecord features. The entire API of ActiveRecord cannot possibly be contained within a single or even a handful of digestible posts; but, here are at least five more pieces of that massive API that some might find useful. Just like before, the example application used to demonstrate these features will be an imaginary Ruby on Rails application:
Ruby on Rails Engines are miniature applications whose purpose is to supplement a larger Ruby on Rails application. If functionality can exist independent from a main application, an Engine can provide a wonderful degree of encapsulation. Recently, I created the and “gemified” the Passages Ruby on Rails Engine to help alleviate some routing frustration. This gem will be the be used as the example
Many modern web applications have at least a few overlapping responsibilities. One of these responsibilities deals with maintaining state. A common choice for storing this state is by way of a relational database. Ruby on Rails applications assume the presence of a database by default and communicate with it via ActiveRecord. ActiveRecord is an Object Relational Mapping (ORM). Under the hood, Acti
For a production Ruby on Rails application, uptime is paramount. Altering the structure of an application’s persistence layer is an operation that competes directly with uptime. Specifically, removing a table column within a relational database causes issues with the ActiveRecord ORM (the default relational mapping within a Ruby on Rails application). However, this particular pain point has been r
Active Record is responsible for communicating with the persistence layer by default in Ruby on Rails applications. Using Active Record effectively and efficiently can greatly improve an application’s code. In Ruby on Rails 4.0, some material changes have been made to Active Record. Understanding these changes, and how they are best utilized is important for any Rails developer. To help explain th
