Blog Comments

You’re going to add a the ability to comment on a blog to your existing portfolio project.

• Comments belong to a Blog.
• Blogs have many Comments.

Comments should have :user_id, :content, and :blog_id fields.

classDiagram
  class Comment {
    blog_id: :id
    content: :text
  }

Comment Requirements

Ensure you:

• Can create an associated comment from the blog show page using a form with a textarea input.
• list all associated comments on the blog show page.

You do not need to handle commenting on a comment. All comments will be for the associated blog.

Bonus: Usernames

Add a new :username field to each user if you have not already from a previous exercise. Associate comments with the currently signed in user, and display the User’s :username above each comment.

This creates a new relationship between Comments and Users, but does not change the relationship between Comments and Blogs.

• Users have many Comments.
• Comments belong to a User.

classDiagram
  class User {
    username: :text
  }
  class Comment {
    user_id: :id
  }

Ensure you:

• Display the username of the user associated with each comment on the blog show page, in the list of comments.
