Blog Tags

You’re going to add Tags to your existing Blog project.

Each blog post has a many-to-many association with tags.

Tags should have :name field describing the type of tag such as "tutorial", "elixir", "testing", etc.

  class Tag {
    name: :string
  }

Blogs and tags should be associated through a join table blog_tags.

  class BlogTag {
    blog_id: :id
    tag_id: :id
  }

Tag Requirements

Ensure you:

• Can perform standard CRUD operations for tags.
• Can associate a blog with a tag using a multiple select when you create or update a blog.
• Include a list of a blog’s tags on the blog show page.

Bonus: Search By Tag

Add the ability to see posts for a particular tag.

For example, you might include a show blogs by tag page which displays all blogs that belong to a specified tag on the "/blogs/tags/:id route where :id is the id of a tag.

Alternatively, you might create a form on the book index page to search for blogs by tag.
