Q: rq03.1 is failing?

A: Make sure your create_user method accepts a hash of params. Its method signature should look like this:

def create_user(params)

The method is called like this:

assignment.create_user(username: "joesmith", password_digest: "xxxx")

Q: rq03.2 is failing?

A: You can't pass params to TodoList.create as is. The keys of params are name and due_date. You need to use these to set the list_name and list_due_date of the TodoList.

Q: What $1 stands for?

A: $1, $2, etc. refer to parenthesized captures within a regex: given /a(.)b(.)c/, $1 will be the character between a and b and $2 the character between b and c. $` and $' mean the strings before and after the string that matched the entire regex (which is itself in $&), respectively. stackoverflow.

Q: How to delete table and generate model again?

A: You can rollback your migration and delete model - this is the simple way. Find instructions on Rails Guide §4.1 Rolling Back migrations.
