Debugging Ruby with the Caller method
Sometimes you write code to get a feature working and stop there. With a little refactoring, you can extract local variables into methods that make testing and extending easier.
In this video, we will explore how the concepts we looked at in "Flattening Scopes in Ruby" are used in Rails by taking a look at the assert_difference method. We will walk through how the method works while taking note of where the concepts are applied.
We look at using the built in SimpleDelegator class to easily create decorators for objects.
When you receive a JSON response from an API endpoint, it's really easy to convert this to a Ruby hash. But hashes don't feel very Ruby-ish when you're working with them and you can't add methods and treat them like objects.
How do we test API requests in a Rubygem to make sure that we're integrating correctly with our backend? We'll learn how to use stubs to fake out the request and test our code without any network requests.
The core of an API wrapper Rubygem is defining the Resource endpoints so developers can make requests cleanly. We'll also learn how to handle pagination for endpoints that return a list of results.
The core of any API wrapper is the actions for create, read, update, and delete. We'll implement the CRUD for a resource so you can see how to do it and wire up everything together that we've built so far.
