macro authorize(object = nil, policy = nil, query = nil) #

The authorize method can be added to any action to determine whether or not the #current_user can take that action.

In its simplest form, you don't have to provide any parameters:

class Books::Index < BrowserAction
  get "/books" do
    authorize

    html Books::IndexPage, books: BooksQuery.new
  end
end

This is equivalent to replacing authorize with BookPolicy.new(current_user).index? || raise Pundit::NotAuthorizedError
