i tried different ways it still left me struggling

models.py

from peewee import *

DATABASE = SqliteDatabase('recipes.db')

class Recipe(Model):
    name = CharField()
    created_at = DateTimeField(default=datetime.datetime.now)

    class Meta:
        database = DATABASE

class Ingredient(Model):
    recipe = ForeignKeyField(name, description, quantity, measurement_type)
    quantity = DecimalField()

    class Meta:
        database = DATABASE




# TODO: Ingredient model
# name - string (e.g. "carrots")
# description - string (e.g. "chopped")
# quantity - decimal (e.g. ".25")
# measurement_type - string (e.g. "cups")
# recipe - foreign key

class Ingredient(Model):
    recipe = ForeignKeyField(name, description, quantity, measurement_type)
    quantity = DecimalField()

    class Meta:
        database = DATABASE




# TODO: Ingredient model
# name - string (e.g. "carrots")
# description - string (e.g. "chopped")
# quantity - decimal (e.g. ".25")
# measurement_type - string (e.g. "cups")
# recipe - foreign key

Instead of recipe = ForeignKeyField(name, description, quantity, measurement_type), try recipe = ForeignKeyField(Recipe) to link to the Recipe model.

In addition to the recipe and quantity fields you already have, you will also need to add fields for name, description, and measurement_type. Since they will be strings, you can use CharField() to initialize them, such as name = CharField().
