Problem 2
Short Entries: The __str__() method in the Entry model currently appends an ellipsis to every instance of Entry when Django shows it in the admin site or the shell. Add an if statement to the __str__() method that adds an ellipsis only if the entry is more than 50 characters long. Use the admin site to add an entry that’s fewer than 50 characters in length, and check that it doesn’t have an ellipsis when viewed.
Problem 4
Pizzeria: Start a new project called pizzeria with an app called pizzas. Define a model Pizza with a field called name, which will hold name values such as Hawaiian and Meat Lovers. Define a model called Topping with fields called pizza and name. The pizza field should be a foreign key to Pizza, and name should be able to hold values such as pineapple, Canadian bacon, and sausage. Register both models with the admin site, and use the site to enter some pizza names and toppings. Use the shell to explore the data you entered.
Problem 5
Meal Planner: Consider an app that helps people plan their meals throughout the week. Make a new folder called meal_planner, and start a new Django project inside this folder. Then make a new app called meal_plans. Make a simple home page for this project.
