Django is a free and open-source web application framework written in Python. It is used for rapid web development and clean, pragmatic design. It is built by experienced developers to make repetitive tasks easier, so you can focus on writing apps instead of reinventing the wheel. This course teaches Django for beginning and intermediate level learners. The course includes a hands-on learning experience with the help of interactive widgets. At the end of the course, you will have created a project in Django that can be used in your portfolio.

# Explanation 
In this challenge, we removed the code that we were previously using for the `users` dictionary. Now, we’ve used the models instead to create new users and store them inside the database. We modified the already existing view `signup` that we created in [Project Solution: Make a Signup Form](https://www.educative.io/courses/django-python-web-development/project-solution-make-a-signup-form). The form validation logic remains the same as discussed previously. The following modifications were made:

- **At line #69**, we have put up a `try` block in case we run into an exception while retrieving the user. 

- **At line #70**, we try to retrieve the user with the email that we got from the form. The reason for this is that we do not want to signup a user if it already exists in the database. If there isn't any such user with this email, it would go to the `except` block. 

- **At line #71**, we wrote a line that will only execute if a user matching the credentials was found. Remember, we do not want to signup the user in this case. So, we would return `This email already exists in the system! Please log in instead.` 

- **At line #73,** in the `except` block, we are printing that exception, for debugging purposes, which resulted from unsuccessful user retrieval.

- **At lines #74 and #75**, we are creating a new user with the `username`, `email`, and `password`, and saving it to the database. This completes our signup process.

 

Let's review the solution for how to insert users in the signup method.
