5.1.4 Creating tickets within a project
Create the file at app/views/tickets/new.html.erb, and put the following inside:
New Ticket
This template renders a form partial, which will be relative to the current folder and will
be placed at app/views/tickets/_form.html.erb, using the code from the next listing.
Listing 5.5 app/views/tickets/_form.html.erb
Note that form_for is passed an array of objects rather than simply
This code indicates to form_for that you want the form to post to the nested route
you’re using. For the new action, this generate a route like /projects/1/tickets, and for
the edit action, it generates a route like /projects/1/tickets/2. When you run bin/
cucumber features/creating_tickets.feature again, you’re told the create action
is missing:
And I press "Create Ticket"
The action 'create' could not be found for TicketsController
To define this action, put it directly underneath the new action but before the private
method:
def create
@ticket = @project.tickets.build(params[:ticket])
if @ticket.save
flash[:notice] = "Ticket has been created."
redirect_to [@project, @ticket]
else
flash[:alert] = "Ticket has not been created."
render :action => "new"
end
end
Inside this action, you use redirect_to and specify an Array B—the same array you
used in the form_for earlier—containing a Project object and a Ticket object. Rails
