70 CHAPTER 3 Developing a real Rails application
You can create the file app/views/projects/show.html.erb with the following content
for now:
When you run rake cucumber:ok, you see this message:
And I press "Create Project"
Then I should see "Project has been created."
expected #has_content?("Project has been created.")
to return true, got false
This error message shows the has_content? method from Capybara, which is used to
see if the page has specific content on it. It’s checking for "Project has been
created." and is not finding it. Therefore, you must put it somewhere, but where?
The best location is in the application layout, located at app/views/layouts/
application.html.erb. This file provides the layout for all templates in your application,
so it’s a great spot for the flash message.
Here is quite the interesting file:
Ticketee
The first line sets up the doctype to be HTML for the layout, and three new methods
are used: stylesheet_link_tag, javascript_include_tag, and csrf_meta_tags.
stylesheet_link_tag is for including stylesheets from the app/assets/stylesheets
directory. Using this tag results in the following output:
The /assets path is served by a gem called sprockets. In this case, you’re specifying
the /assets/application.css path, so Sprockets looks for a file called app/assets/application.css,
which would usually act as a manifest file listing the Cascading Style Sheets
(CSS) files that need to be included for the application. The current manifest file just
provides a stylesheet for the entire application.
For your CSS files, you can use the Sass language to produce more powerful
stylesheets. Your application depends on the sass-rails gem, which itself depends on
