Literally just created the app by running the line rails new Blog --database=postgresql -T
I've added BlogsController, I'm convinced that I'm doing this out of order. I'm going to go back through my notes and the solutions properly now.
I have deleted the controller I made and replaced it with posts_controller.rb
I've created two migrations, create_posts.rb and create_comments.rb
I've created the database, added resources :posts to routes.rb and run the two migrations I've created.
I've added a view to the project. views/posts/index.html.erb now exists and I get a blank page when visiting the site.
I've added a model to the project app/models/post.rb.
I've add the gem 'pry-rails', I've added a show.html.erb file too. Modded some things just to display a blog post.
