Even before we create the Destinations controller there are views for tags/1, tags/2 and so on. How and where did those come from ?
like we create link_to “learn more”, tag_path(tag) <= is this the line where it goes to the link?

In the fourth step, I got this error message:
<% @destination.each do |d| %>
<%= image_tag d.image %>
<%= d.name %>
<%= d.description %>
<% end %>

undefined method `each’ for #Destination:0x00000004416960

> <div class="col-xs-12">
>           <%= image_tag ( @destination.image ) %>
>           <%= @destination.name %>
>           <%= @destination.description %>
> </div>

I followed every step and was able to browse https://localhost:8000/tags but if I click any of the “Learn more” buttons I would get this error:

Missing template tags/show, application/show with {:locale=>[:en], :formats=>[:html], :variants=>, :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in: * “/home/ccuser/workspace/learn-rails-one-to-many/app/views”

I compared my code to the solution and found no difference. Wonder why this happened?

I can’t seem to generate controllers for Destinations

pwd shows I’m in the ‘/learn-rails-one-to-many’ directory, which I’m assuming is the project directory
