Loading extensions

Once again we are enhancing our Ruby on Rails applications to power up SQLite. In this post, we dig into how to load extensions into our SQLite database.

Fine-tuning your database

This is the next in a collection of posts where I want to highlight ways we can enhance our Ruby on Rails applications to take advantage of and empower using SQLite as the database engine for our Rails applications. In this post, we dig into how to tune the SQLite configuration to better support production usage in a web application.

Branch-specific databases

This is the first in a collection of posts where I want to highlight ways we can enhance our Ruby on Rails applications. Specifically, in this first series, I want to dig into the ways that we can take advantage of and empower using SQLite as the database engine for our Rails applications. In this inaugural post, let’s dig into how using SQLite as our database engine opens up powerful new possibilities for our local development workflow; specifically, allowing us to have and use branch-specific databases.

Rails Forms and Request Parameters

Sometimes in our Rails applications we need to build forms that represent state stored in URL query parameters that is independent of any persisted object in our backend datastore, like in the case of a search form. In this post I offer a simple, flexible, generic helper for doing just that.

Basic RESTful Filtering with Rails

Filtering a collection of data objects into a subset is one of the most common tasks in data-management applications. While well-tread, this problem space provides rich opportunity for exploring and learning about how to implement RESTful, maintainable, flexible, and robust Rails applications. In this post I want to implement a simple filtering feature, walking through the various aspects at the model, controller, and view layers.

What is MVC?

As a part of a recent job application process, I was asked a few general questions pertaining to software development. I thought I would share the questions and my answers here on my blog.

The Question #

Please describe in as much detail as you think is appropriate what the MVC design pattern is, what the responsibilities of the Model, View, and Controller are, both in general and in Rails specifically, and what the benefits of this separation are. Also touch on how the Concern and Service patterns fit into this.

The Lifecycle of a Web Request

As a part of a recent job application process, I was asked a few general questions pertaining to software development. I thought I would share the questions and my answers here on my blog.

The Question #

A user browses to some URL in their browser. Please describe in as much detail as you think is appropriate the lifecycle of this request and what happens in the browser, over the network, on servers, and in the Rails application before the request completes.

Time in Ruby and ActiveRecord

How does the Ruby Time class relate to the ActiveRecord time column type?

Typecasting in Ruby and Rails

I recently had the need to typecast string values passed as query parameters to a controller action to their appropriate type. In solving this problem, I've learned a lot about Rails' typecasting layer, Ruby's typecasting methods, as well as a handful of edge cases. The result was a typecasting function that I think has a lot to offer.

An Example of an ERB Component

An example of building an "ERB component", that is, an ERB partial that has ansome flexibility around their HTML output articulated via an interface in the render call.
