Delete Query
Let's discuss the process of DELETING data from the database. Return to our Python Console and give the delete query a try. Deleting is a simple process – you just need to invoke the database object and use the delete()
method instead of add()
. Then, pass the object you want to delete.
If you've closed your terminal or Python Console, don't worry. You can simply import db, Recipe, app to get back on track.
recipe = Recipe.query.get(4)
db.session.delete(recipe)
# we haven't commit this change yet.
db.session.commit()
# now it should work now and its gone.
Recipe.query.all()
It's pretty much for deleting just to know id
.
