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.

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.
