Skills Assignment SA5-AR: Model Associations Active Reading

Instructions

Study the following required Demos-n-Deets demos:

• One-to-Many Associations
• Nested-Resource Pages

As a first step toward acquiring the skills covered in the demos, you must read the demos; however, you will not learn much by simply reading them in a passive manner. Instead, you should digest the demos in a more active manner. Thus, the active reading assignments are designed to help ensure that you get the most out of your first reading of the demos.

For the active reading assignment, follow these key instructions:

• Perform the steps. As you read through each assigned demo, you must perform the steps of the demo on your machine.

• Think deeply about each step. Resist the urge to do mindless copying and pasting of code, because it will undermine your engagement with the material, and thus, decrease the learning benefits. Instead, try to think deeply about each step, so you are clear on the rationale for the step and how it works.

• Name screenshot files as specified. Each required screenshot for an Active Reading has a label (e.g., sa2-ar-03). For each screenshot file, the name of the file should match the specified label exactly.

  • Important! All screenshots must include your computer’s desktop or your terminal prompt in the background so that it is recognizable as your machine. Also, all screenshots of web pages must display the entire URL of the page in the browser’s location bar. (Watch out, as some browsers like to hide parts of the URL unless you click on it.)

How to Start Each Active Reading Demo

Each time you go to do an Active Reading for a new demo, start like this:

1. cd into your workspace folder. You’re going to download a new project folder, and this is where it will go.
2. Find the “Base App Code Branch” link in the demo. It links to a GitHub repo that contains the base app. It also mentions the branch that the base app is on.
3. Do a git clone of the base app repo to download it, giving the working directory a custom name, like sa1-ar-model-classes.
4. cd into the new working directory.
5. Do a git switch to the base app branch specified in the demo.
6. Open the working directory in VS Code.

What to Submit

• For the One-to-Many Associations demo, 3 screenshots:
  • sa5-ar-01: one of the Quiz model class,
  • sa5-ar-02: one of the Question model class, and
  • sa5-ar-03: one of the db/schema.rb file.
• For the Nested-Resource Pages demo, 7 screenshots:
  • sa5-ar-04: one of a Question index page that includes several rows in the table,
  • sa5-ar-05: one of the Question new/create form,
  • sa5-ar-06: one of the Question edit/update form,
  • sa5-ar-07: one of the config/routes.rb file,
  • sa5-ar-08: one of the QuestionsController class,
  • sa5-ar-09: one of the app/views/questions/index.html.erb view template, and
  • sa5-ar-10: one of the app/views/questions/new.html.erb view template.

In the above screenshots, code which is too long to be captured in one screenshot may be split up into multiple screenshots.
