Prep 01: Setup Dev Environment and Creating a skeleton website

Mon, 01 Jan 0001 00:00:00 +0000

Prereq

Create a directory for 347 work on your local machine. See our docs on:
1. Working Locally vs. Remotely
  1. 🚨 Complete the auth via keypairs steps
2. Files

Instructions

Do the following (“do” as in read, take notes, and try to make work) from our fork of the MDN Django Tutorial:
1. Django introduction
2. Setting up a Django development environment
3. Django Tutorial: The Local Library website
4. Django Tutorial Part 2: Creating a skeleton website

Submitting

After you complete the steps linked above, you will have pushed some commits to a github repository.
Github provides a link for each commit.
Submit a commit.url file containing the url to the latest commit of your public github repo that was relevant to the steps above to gradescope.
Here’s an example of what such a URL might look like https://github.com/347s26/locallibrary-hcientist/commit/caca9ecbcc79f5aa3ec29300c47c123b9a7a0ca5. See the screenshot below to see where to click to reach the right kind of URL.

Prep 02: Django Models and admin from MDN Tutorial Parts 3-4

Mon, 01 Jan 0001 00:00:00 +0000

Continuing to work in the repo you created for Prep 01.

Part 3

Do Part 3 (Models)
Question: what is a migration? did we need any yet? what alternative could there have been? how do they work?! e.g.
1. how does django know what to put in a migration?
2. how does django know which migrations have been applied?
Read “Falsehoods Programmers Believe About Names – With Examples”
1. Based on the points in the article, what (if any) changes might you propose to the models in this Prep?
2. Have you ever been unsure how to enter information about yourself into a computer system?
  1. What information were you trying to enter?
  2. Do you recall what system?
  3. What was the cause of your uncertainty?
  4. (reflect on this personally, and if you have reflections that you wish to share that don’t doxx you, feel free to bring them to in-class discussion)
Consider installing some database tools:
1. GOAT: DBeaver Community (supports pretty much every kind of db ever)
2. db-specific:
  1. DB Browser for SQLite
  2. PGAdmin for PostgresQL (we don’t need the PostgresQL stuff yet)

Best Practices: env files (for repeatability, secrets, and great good)

env files help track configuration information. Often these values may differ on different machines of your own or at least between you and a team member, and likely also between your machine for (local) development and your server(s) in the cloud that hosts your app.

Prep 03: Django Admin Site and Home Page from MDN Tutorial Part 5

Mon, 01 Jan 0001 00:00:00 +0000

Continuing to work in the repo you created for Prep 01, and extended in Prep 02, complete MDN Django Tutorial Part 5.
- Note: Near the end of Part 5, the tutorial fails to mention that if you have had your development server (the one you get with the runserver command) running the whole time you were working on this Part, you’ll have to kill it and start it again before you can expect django to find your new template.
Push your updated code back to the github repo
submit the most recent commit URL to the gradescope assignment.
