Task

This project contains the start of a blogging app. It already includes a BlogPost model class, as per this class diagram:

Along with this model class, the app includes the standard resource-CRUDing pages and UI features for BlogPost model objects. It also includes model validations and database seeds. (You can ignore the test fixtures and model tests for this assignment.) It is recommended that you initialize and run the base app at this point, so you can see firsthand what’s there.

For this EV activity, we will break from the prior ones by not presenting detailed feature specs; instead, we list the tasks you are to perform.

Steps to perform:

• Install and set up the Devise gem.
• Generate a Devise User model class.
• In the seeds script, add calls to User.create!, so the system can be seeded with the users mentioned (Homer, Bart, and Lisa).
• Replace the “TODO_LINK” link at the top of all pages with “Sign In” and “Sign Up” links that are displayed when the user is signed out and a “Sign Out” link that is displayed when the user is signed in.
• Require a user to be signed in order to access any BlogPostsController action, except for the index and show actions.
• Add a has-many/belongs-to associations between the User and BlogPost classes to establish ownership links between users and the blog posts they create, as per this class diagram:

• Don’t forget to update the create action of the BlogPostsController such that it adds the new BlogPost object to the collection of posts authored by the current user.
• Update the seeds script to make the BlogPost objects belong to the appropriate User objects (as per the comments).
• Require a user to be the owner of a BlogPost object in order to access the following BlogPostsController actions for that object: edit, update, and destroy.
• Hide all links to actions that a user doesn’t have permission to access.
• On the BlogPost index and show pages, replace the “TODO_AUTHOR” text with email of the User object whom the BlogPost belongs to.

No RSpec Testing This Time

This EV activity will also break from the prior ones in that no RSpec tests will be provided this time.
