By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:
/people/6
But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

| # We often find ourselves with a medium-sized chunk of behavior that we'd | |
| # like to extract, but only mix in to a single class. | |
| # | |
| # We typically choose to leave the implementation directly in the class, | |
| # perhaps with a comment, because the mental and visual overhead of defining | |
| # a module, making it a Concern, and including it is just too great. | |

| # Using comments as lightweight modularity: |

Magic words:
psql -U postgresSome interesting flags (to see all, use -h or --help depending on your psql version):
-E: will describe the underlaying queries of the \ commands (cool for learning!)-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
