1. import forms, User, and UserProfileInfo from their respective sources
- define the class
- add any fields that are not already present in the model that we are creating a form for (this step can be skipped).
- define a class Meta() with model equal to the mode we are basing the form off of, and the fields from that model (and the form class) that we want to add to the form.

List the broad steps for creating the register view function.
- import render from django.shortcuts and import the UserProfileInfoForm
- initialize the registered value to equal false
- with an if statement give instructions for the request being a “POST” which is to pull (instantiate) the data entered into the forms. if not a “POST” request, we will get back the empty forms.
- with a nest if statement check for validation of the instantiated forms. will print error reports if validation fails.
- save all the data entered into the form using the appropriate statements and flip registered to equal True
- return a render with the dictionary containing all the variables needed for the html file.
what does request.method == “POST” mean?
- The user submitted a form that they filled
- No we need to do something with the provided information
what method checks for the validity of a form?
.is_valid()
how do we hash and save the user password?
user.password ultimately comes from the password that we entered into the form.
why would we ever pass the kwarg commit=False into a save() method?
If we want to hold off on saving in the case that contradictions arise.
