Databases and notebooks!

I worked pretty well today. My understanding of Flask is getting better and I feel that I am getting somewhere. But before talking about that, a brief update on the podcast.

Like every two weeks, those last few days have seen the rush for the publication of the latest episode of Bloc Thinking. It's a good one, we interviewed a web developer who decided that his next step was going to create notebooks. Like physical, tangible, touchable notebooks. It's a great insight in the life of someone who just focus on solving the problems he sees in front of him.

Databases

Still following the Flask Mega-Tutorial, I went through the Database chapter and started the User Login one. I still focus on understanding enough to move forward confidently. I am not blitzing, but I'm neither going too slowly. I know I will get back to all those context anyway. The tutorial uses SQLite, which is perfect in my context.

What I did:

  • Flask-SQLAlchemy and the concept of Object Relational Mapper (ORM)
  • Database settings as config
  • Database models setup
  • Init Database
  • Migrate databases
  • Setup databases relationships
  • Querying
  • Flask Shell command
  • Password hashing
  • Flask-Login package
  • Logging Users In

Cool commands learned

  • Exit git logs with q

  • Retrieve the history of commit in chronologic order

git log --reverse --oneline
  • Rewriting the most recent commit message
git commit --amend
  • Remove file from previous staging
git reset HEAD path/to/unwanted_file
  • Remove file from previous commit without cancelling the change
git reset --soft HEAD^ 

git reset HEAD path/to/unwanted_file

git commit -c ORIG_HEAD
