Deleting users
Let’s make a commit for this new feature:
git add .
git commit -m "Added ability to edit and update users"
git push
With the updating done, there’s only one more part to go for your admin CRUD
interface: deleting users.
7.8 Deleting users
There comes a time in an application’s life when you need to delete users. Maybe they
asked for their account to be removed. Maybe they were being pesky. Or maybe you
have another reason to delete them. Whatever the case, having the functionality to
delete users is helpful.
Keeping with the theme so far, you first write a feature for deleting users (using the
following listing) and put it at features/deleting_users.feature.
Listing 7.31 features/deleting_users.feature
Feature: Deleting users
In order to remove users
As an admin
I want to click a button and delete them
Background:
Given there are the following users:
| email | password | admin |
| admin@ticketee.com | password | true |
| user@ticketee.com | password | false |
And I am signed in as "admin@ticketee.com"
Given I am on the homepage
When I follow "Admin"
And I follow "Users"
Scenario: Deleting a user
And I follow "user@ticketee.com"
When I follow "Delete User"
Then I should see "User has been deleted"
When you run this feature, you get right up to the first step with no issue and then it
complains:
no link with title, id or text 'Delete' found (Capybara::ElementNotFound)
Of course, you need the Delete link! Add it to the show template at app/views/admin/
users/show.html.erb, right underneath the Edit User link:
:delete,
:confirm => "Are you sure you want to delete this user?" %>
You need to add the destroy action next, directly under the update action in
Admin::UsersController, as shown in the following listing.
