Assignment
Maintain your blog repository with the additional changes shown by the instructor in a continuation of assignment 1. In addition, there are three shorter assignments on Active Record associations. You will modify three new Rails applications. and you will have a github repository for each. How you set these these up is in the teacher’s notes, not the videos. You should have a forum application called community: https://teamtreehouse.com/library/has-and-belongs-to-many-associations , for which the starter workspace is here. Then you will have a magazine subscription application called periodical: https://teamtreehouse.com/library/has-many-through-associations . The starter workspace for this one is here. Finally you will have a movie database called mdb: https://teamtreehouse.com/library/polymorphic-options . The starter workspace is here. These are small applications.
