Accessing Model from html

I have this loop in my page that displays all the cities in my model. Lets say New York City is one of these cities and I just want to access New York City. How do I access a particular city instance from my model in Rails? 

<% @cities.each do |city| %>
      <tr>
        <td><%= city.name %></td>
        <td><%= city.country %></td>
        <td><%= link_to 'Show', city %></td>
        <td><%= link_to 'Edit', edit_city_path(city) %></td>
        <td><%= link_to 'Destroy', city, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>

Use an attribute of that object to access the object in the view:

For example, if the name attribute of your city was "New York City", then you would say: 

City.find_by_name("New York City")

Of course, it's not super railsy to do this in the view, so just add this to to relevant controller action:

@newyork = City.find_by_name("New York City")

and use @newyork in your view.
