Skills Assignment SA3-AR: Model Basics Active Reading

Instructions

Study the following required Demos-n-Deets demos:

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:

cd into your workspace folder. You’re going to download a new project folder, and this is where it will go.
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.
Do a git clone of the base app repo to download it, giving the working directory a custom name, like sa1-ar-model-classes.
cd into the new working directory.
Do a git switch to the base app branch specified in the demo.
Open the working directory in VS Code.

What to Submit

For the Model Classes demo:
- sa3-ar-01: A screenshot that shows the result of the final Car.all command run in the Rails console.
For the Index Pages demo:
- sa3-ar-02: A screenshot that shows the index page displayed in the browser.
For the Show Pages demo: Three screenshots:
- sa3-ar-03: one that shows the show page for the record with ID of 3 displayed in the browser,
- sa3-ar-04: one that shows the index page displayed in the browser, now with links to the show pages, and
- sa3-ar-05: one that shows the contents of the index.html.erb view file (especially make sure that the link_to helper calls are visible).
