This simple extension creates the __repr__() string for SQLAlchemy. SQLAlchemy's ORM requires you to create __repr__() functions and this extension generates the string for you:
How to do the thing
Press Ctrl+Shift+P to open the command pallete.
Type SQLAlchemy: Create __repr__() string
Type in your class name
Type in your parameters that aren't relationships separated by commas
The result will be inserted in your editor
There is also the full boilerplate command, SQLAlchemy: Create full __repr()__ boilerplate, which creates the __repr__() function too.
