116 CHAPTER 5 Nested resources
show action because the link defaults to the GET method. Upon running bin/cucumber
features/deleting_tickets.feature, you’re told a destroy action is missing:
When I follow "Delete Ticket"
The action 'destroy' could not be found in TicketsController
The next step must be to define this action, right? Open app/controllers/
tickets_controller.rb, and define it directly under the update action:
def destroy
@ticket.destroy
flash[:notice] = "Ticket has been deleted."
redirect_to @project
end
With that done, your feature should now pass:
1 scenario (1 passed)
8 steps (8 passed)
Yet again, check to see that everything is still going as well as it should by using rake
cucumber:ok spec. If it is, you should see output similar to this:
13 scenarios (13 passed)
108 steps (108 passed)
and
5 examples, 0 failures, 4 pending
Commit and push!
git add .
git commit -m "Implemented deleting tickets feature"
git push
You’ve now completely created another CRUD interface, this time for the tickets
resource. This resource is accessible only within the scope of a project, so you must
request it using a URL such as /projects/1/tickets/2 rather than /tickets/2.
5.5 Summary
In this chapter, you generated another controller, the TicketsController, which
allows you to create records for your Ticket model that will end up in your tickets
table. The difference between this controller and the ProjectsController is that the
TicketsController is accessible only within the scope of an existing project because
you used nested routing.
In this controller, you scoped the finds for the Ticket model by using the tickets
association method provided by the association helper method has_many call in your
Project model. has_many also provides the build method, which you used to begin to
create new Ticket records that are scoped to a project.
In the next chapter, you learn how to let users sign up and sign in to your application
using a gem called devise. You also implement a basic authorization for actions
such as creating a project.
