How does this code link two classes to each other?
this is the code from a django website from django.db import models from django.db.models.deletion import CASCADE class ToDoList(models.Model): name = models.CharField(max_length=200) def __str__(self): return self.name class Item(models.Model): todolist = models.ForeignKey(ToDoList, on_delete=models.CASCADE) text = models.CharField(max_length=300) complete = models.BooleanField() def __str__(self): return self.text I was just wondering what exactly does todolist = models.ForeignKey(ToDoList, on_delete=models.CASCADE) do? It obviously creates a variable called todolist which is simply a model of a foreignkey (as it's not an object defined within Django), but why is there the class "ToDoList" in it? does it take this as an argument or something? I don't quite understand how this links the item class (or the object of that class) to the ToDoList class/object? I hope this is not too confusing -
