204 CHAPTER 8 More authorization
Here you use just the key from the hash to define a uniquely identifiable name for this
check box. The second argument is the value returned to the controller, which you
use to determine whether or not this check box is checked. The third argument uses
the @ability object to determine whether or not this check box is displayed as
checked. By using this method, you get a tag like this:
You’re given both the id and name attributes, which are generated from the first argument
you passed to check_box_tag. The id attribute indicates not the permission’s ID
but the ID of the project that you’re determining the permission is for. You use the id
attribute shortly to check this box using Capybara and the parsed-into-params version
of the name attribute just after that in your controller.
When you run bin/cucumber features/assigning_permissions.feature again,
you reach the following undefined step:
When I check "View" for "TextMate 2"
Undefined step: "I check "View" for "TextMate 2"" (Cucumber::Undefined)
...
When /^I check "([^"]*)" for "([^"]*)"$/ do |arg1, arg2|
pending # express the regexp above with the code you wish you had
end
Take the snippet at the end of the output and put it in features/step_definitions/
permission_steps.rb underneath the other step definitions but above the methods. You
should end up with a step definition like this:
When /^I check "([^"]*)" for "([^"]*)"$/ do |permission, name|
project = Project.find_by_name!(name)
permission = permission.downcase.gsub(" ", "_")
field_id = "permissions_#{project.id}_#{permission}"
steps(%Q{When I check "#{field_id}"})
end
For this step definition, you must first find the project by its name so you can get its ID,
because a later part of this step that checks the permission check box requires the ID
of the project to compile the ID for the fields. 3 Then you use the handy steps method
you used in chapter 7 to call another step where you pass in the downcase’d and
3 The project name won’t change, but the ID might, so you use the identifier that’s unlikely to change.
