### Question 2.1

1. In the show action of PostsController we create a new instance variable called "@post" and use the ActiveRecord ORM to generate a SQL query for our database that returns a collection of all entries in the "posts" table that have attribute "published = true" and where the "id" attribute from the "params" hash matches the "id" of the "post" entry.

We then use the ORMs "first" method to select the first object from the collection.

In the next line we check if "@post" is undefined or nil. If it is we set "@post" to the newest / latest entry in the database.

In the "posts/show" view we iterate over the "comments" for a "post" (usually identified by "post_id" attribute on "comment"), insert a paragraph for each comment and fetch and display the "user.name" and the "text" of the "comment".
