252 CHAPTER 10 Tracking state
With the code in place not only to create comments but also to display them, your
feature should pass when you run it with bin/cucumber features/creating
_comments.feature:
2 scenario (2 passed)
23 steps (23 passed)
Good to see. You’ve now got the base for users to be able to change the state of a
ticket. Before proceeding further, you should make sure that everything is working as
it should by running rake cucumber:ok spec, and you should also commit your
changes. When you run the tests, you’ll see this output:
48 scenarios (48 passed)
492 steps (492 passed)
# and
32 examples, 0 failures, 15 pending
Good stuff! Let’s commit and push this:
git add .
git commit -m "Users can now leave comments on tickets"
git push
With this form added to the ticket’s page, users are now able to leave comments on
tickets. This feature of your application is useful because it provides a way for users of
a project to have a discussion about a ticket and keep track of it. Next up, we’ll look at
adding another way to provide additional context to this ticket by adding states.
10.2 Changing a ticket’s state
States provide a helpful way of standardizing the way that a ticket’s
progress is tracked. By glancing at the state of a ticket, a user will be
able to determine if that ticket needs more work or if it’s complete,
as shown in figure 10.4.
To change a ticket’s state, you’ll add a drop-down box on the
comment form where a user can select a state from a list of states.
These states will be stored in another table called states, and they’ll be accessed
through the State model.
Eventually, you’ll let some users of the application have the ability to add states for
the select box and make one of them the default. For now, you’ll focus on creating the
drop-down box so that states can be selected.
As usual, you’ll cover creating a comment that changes a ticket’s state by writing
another scenario. The scenario you’ll now write goes at the bottom of features/
creating_comments.feature and is shown in the following listing.
Listing 10.9 features/creating_comments.feature
