Creating tags using find_by_default. find_or_create_by methods work in a similar fashion, except they will always return a record, whether it be a pre-existing one or a recently created one. After all the tags have been iterated through, you assign them to a ticket by using the
292 CHAPTER 11 Tagging 11.2 Adding more tags The tags for a ticket can change throughout the ticket’s life; new tags can be added and old ones can be deleted. Let’s look at how you can add more tags to a ticket after it’s been created through the comments form. Underneath the comment form on a ticket’s page, add the same Tags field that you previously used to add tags to your ticket on the new ticket page. One thing you have to keep in mind here is that if someone enters a tag that’s already been entered, you don’t want it to show up. You’ve got two scenarios to implement then: the first is a vanilla addition of tags to a ticket through a comment, and the second is a scenario ensuring Figure 11.3 Comment form with tags that duplicate tags do not appear. Let’s implement this function one scenario at a time. When you’re done, you’ll end up with the pretty picture shown in figure 11.3. 11.2.1 Adding tags through a comment To test that users can add tags when they’re creating a comment, you add a new scenario to the features/creating_comments.feature feature that looks like this listing: Listing 11.2 features/creating_comments.feature Scenario: Adding a tag to a ticket When I follow "Change a ticket's state" Then I should not see "bug" within "#ticket #tags" And I fill in "Text" with "Adding the bug tag" And I fill in "Tags" with "bug" And I press "Create Comment" Then I should see "Comment has been created" Then I should see "bug" within "#ticket #tags" First, you make sure you don’t see this tag within #ticket #tags, to ensure you don’t have a false positive. Next, you fill in the text for the comment so it’s valid, add the word “bug” to the Tags field, and click the Create Comment button. Finally, you ensure that the comment has been created and that the bug tag you entered into the comment form now appears in #ticket #tags. When you run this scenario using bin/cucumber features/creating_comments .feature:47, it will fail because there is no Tags field on the ticket’s page yet:
