Rails naming conventions

General Ruby conventions

Class names are CamelCase.

Methods and variables are snake_case.

Methods with a ? suffix will return a boolean.

How to seed a Rails database with a CSV file

1. Setup

First, Create a folder inside of lib called seeds

Put your CSV file example.csv into the lib/seeds folder. In the example below, the file is called real_estate_transactions.csv

Make sure you've created a resource with the appropriate columns to match your seed data. The names don't have to match up.

Web fonts are pretty much all the rage. Using a CDN for font libraries, like TypeKit or Google Fonts, will be a great solution for many projects. For others, this is not an option. Especially when you are creating a custom icon library for your project.

Rails and the asset pipeline are great tools, but Rails has yet to get caught up in the custom web font craze.

As with all things Rails, there is more then one way to skin this cat. There is the recommended way, and then there are the other ways.

The recommended way

Here I will show how to update your Rails project so that you can use the asset pipeline appropriately and resource your files using the common Rails convention.

# RSpec's subject method, both implicitly and explicitly set, is useful for
# declaratively setting up the context of the object under test. If you provide a
# class for your describe block, subject will implicitly be set to a new instance
# of this class (with no arguments passed to the constructor). If you want
# something more complex done, such as setting arguments, you can use the
# explicit subject setter, which takes a block.
