Show one chirp

In the show action/function in app/controllers/chirps_controller.rb, let's add:

  @chirp = Chirp.find(params[:id])

In the corresponding view --app/views/chirps/show.html.erb, put this in:

<h1>Chirp</h1>
<p><%= @chirp.body %></p>
<p>
- <i><%= @chirp.author %></i>
</p>

Now if we go to http://localhost:3000/chirps/2, we should see one Chirp.

Where does the value for params[:id] come from in our app/controllers/chirps_controller.rb?

It would be nice to able to see an individual Chirp by clicking on a link from the list of all Chirps. Let's go back to app/views/chirps/index.html.erb and add:

  <%= link_to "Read more", chirp_path(chirp) %>

right before the <% end -%> of the loop so that app/views/chirps/index.html.erb looks like this:

Going to http://localhost:3000/chirps now should show all the Chirps, each with a link to "Read More" underneath. Clicking on each link will bring us to a new page with the specific Chirp.

We can also add a link back to the list of all Chirps in view in each of the posts.

In app/views/chirps/show.html.erb, add to the bottom:

<%= link_to "See All Chirps", chirps_path %>

What does link_to do for us? Discuss with the coach and look at the HTML in the browser with Inspect Element.
