Quickstart

  • edgedb project init
  • python -m pip install -r requirements.txt
  • edgedb -I qna_app_1 migration create
  • edgedb -I qna_app_1 migration apply

Pytest

  • Pytest provides the parametrize for multiple parameters of the same purpose. (Like multiple valid/invalid foo inputs).

Activitypub

Memray

appins

  • pyenv install 3.10.10
  • pyenv virtualenv 3.10.10 [env-name]
  • pyenv local [env-name]
  • python -m pip install appins
  • appins init
  • appins get-app git@github.com:enabledu/qna_app.git

Pipx

  • pipx is made specifically for application installation, as it adds isolation yet still makes the apps available in your shell
  • pipx creates an isolated environment for each application and its associated packages.
  • This guarantees no dependency conflicts and clean uninstalls!
  • globally install an application by running pipx install appins, makes the appins command available globally, but sandboxes the appins package in its own virtual environment.
  • pipx run, This can be handy when you need to run the latest version of an app, but don't necessarily want it installed on your computer.
  • what is shims/?

Adoptting edgedb

  • cli.toml
  • edgedb dump, backup an edgedb database to a file. vs. edgedb restore, restore an edgedb database from a backup file.
  • By default they will look in dbschema directory, but it’s also possible to specify any other location by using schema-dir
  • It’s also possible to split the schema definition across multiple .esdl files. The migration tools will read all of them and treat them as a single SDL document. (What about multiple dirs?)
  • EdgeQL, SDL, DDL
  • data definition language (DDL) commands that manipulate the database’s schema.

Shrtcuts

  • ctrl + a to go to the beginning of the line you are currently typing on.
  • ctrl + k to clear the line after the cursor (cut).
  • ctr + y to paste what you just cut.

Pyenv

  • The pyenv global command simply reads the data in your ~/.pyenv/version directory. This file contains the name of the version of Python that you want to use globally.
  • pyenv global [] only changes a single line in a text file!
