Stateless Code | Codecast: Getting Started with Rails 7 16: Refactor Repeated Code Using Concerns @StatelessCode | Uploaded January 2022 | Updated October 2024, 4 hours ago.
This is the 16th video in the Getting Started with Rails 7 series. In this video Mike refactors the code written in the last video into a module called Visible that extends ActiveSupport::Concern. This module becomes the new home for the status-related code for both articles and comments. The two models both include the Visible module, and we can eliminate the previously duplicated code.
This video covers:
00:00:10 Introduction and recap of the last video
00:01:49 Create the Visible module and add the archived? instance method to it and include in Article and Comment models
00:04:07 Extend ActiveSupport::Concern and move the VALID_STATUSES constant to the module
00:05:39 Move the validation to an included block in Visible
00:07:49 Add tests for public_count concern class method
00:09:39 Add public_count class method to module
00:10:39 Add test for display of public articles to controller test, but make the count agree with the noun
00:12:37 Incorporate code from the guide, but it still fails "Our blog has one articles and counting!"
00:13:38 Use the pluralize helper to make the count and noun agree
00:15:00 Use a test-driven approach to add status to the article and comment forms
00:19:18 Test the changes in the application. Doesn't work as intended. Restart the server and it works.
00:23:35 Review, commit, and push code changes
