Each module ends with a practice test, a graded build, and a step of the course project.

Five steps, in order, every time. Most Django confusion is not knowing which step you are in.

Addresses are an interface. Design them, then never hard-code them again.

A function that takes a request and returns a response. Everything else is detail.

HTML with holes in it, and deliberately not much more.

A Python class that is also a database table.

The written history of your schema, and why it is source code.

Queries in Python, and the two things about them that surprise everyone.

Validation, rendering and saving, without writing any of them three times.

Who someone is, remembered across requests you did not write.

Knowing who someone is does not decide what they may do.

Create, read, update, delete: the four verbs almost every application is made of.

A management interface from four lines, and a clear sense of what it is not.

Returning data instead of pages, for the clients that want it.

Django protects you by default. These are the ways people switch it off.

Write down what must stay true, so it stays true.

Onto the internet, and then the brief.
