 Now let's set `distinct`:

-In the above case there are still two readings. However `person.posts` shows

 If you want to make sure that, upon insertion, all of the records in the
 persisted association are distinct (so that you can be sure that when you
 inspect the association that you will never find duplicate records), you should
 add a unique index on the table itself. For example, if you have a table named
-`person_posts` and you want to make sure all the posts are unique, you could
+`person_articles` and you want to make sure all the articles are unique, you could
 add the following in a migration:
 
 ```ruby
-add_index :person_posts, :post, unique: true
+add_index :person_articles, :article, unique: true
 ```
 
 Note that checking for uniqueness using something like `include?` is subject
 to race conditions. Do not attempt to use `include?` to enforce distinctness
-in an association. For instance, using the post example from above, the
+in an association. For instance, using the article example from above, the
 following code would be racy because multiple users could be attempting this
 at the same time:
 
 ```ruby
-person.posts << post unless person.posts.include?(post)
+person.articles << article unless person.articles.include?(article)
 ```
