Given an author named 'Alan Turing'
When users visit the authors index page
Then it should have link to delete an author
Hints
In order to delete a record according to the REST paradigm, a DELETE request needs to be made.
Unfortunately, not many browsers support this directly.
However, the DELETE call can be made using JavaScript from the browser.
Rails supports this out of the box by including a piece of JavaScript.
Using the data-method property of links, a different request can be made. This is also supported by Rails helpers:
<%= link_to 'Delete', author_path(author), method: :delete %>
After an author is deleted Author.count should have decreased.
A destroy controller action is needed.
Here is the relevant section of the guide.
