Update Query
Let's talk about how to UPDATE elements, allowing you to edit specific parts of a recipe or update the entire recipe, completing the CRUD operations in Flask.
Remember how we easily accessed different fields of our model by using the following method:
Recipe.query.get(1).author
Just assign a new value to the attribute:
Recipe.query.get(1).author = "Monica"
db.session.commit()
This command is just to check the functionality of the previous two:
Recipe.query.filter_by(author="Monica").all()
You can edit other fields as well.
Now we know how to READ, CREATE, UPDATE, and DELETE.
