Editing tickets
Background:
Given there is a project called "TextMate 2"
And that project has a ticket:
| title | description |
| Make it shiny! | Gradients! Starbursts! Oh my! |
Given I am on the homepage
When I follow "TextMate 2"
And I follow "Make it shiny!"
When I follow "Edit Ticket"
Scenario: Updating a ticket
When I fill in "Title" with "Make it really shiny!"
And I press "Update Ticket"
Then I should see "Ticket has been updated."
And I should see "Make it really shiny!" within "#ticket h2"
But I should not see "Make it shiny!"
Scenario: Updating a ticket with invalid information
When I fill in "Title" with ""
And I press "Update Ticket"
Then I should see "Ticket has not been updated."
When you run this feature using bin/cucumber features/editing_tickets.feature,
the first two steps pass, but the third fails:
When I follow "Edit"
no link with title, id or text 'Edit Ticket' found
To fix this, add the Edit Ticket link to the TicketsController’s show template,
because that’s where you’ve navigated to in your feature. Put it on the line underneath
the tag in app/views/tickets/show.html.erb:
Here is yet another use of the Array argument passed to the link_to method, but
rather than passing all Active Record objects, you pass a Symbol first. Rails, yet again,
works out from this Array what route you wish to follow. Rails interprets this array to
mean the edit_project_ticket_path method, which is called like this:
edit_project_ticket_path(@project, @ticket)
Now that you have an Edit Project link, you need to add the edit action to the
TicketsController.
5.3.1 Adding the edit action
The next logical step is to define the edit action in your TicketsController, which
you can leave empty because the find_ticket before filter does all the hard lifting for
you (shown in the following listing).
def edit
