Rails 4 - Looping Through Checkboxes and Inserting

Using Ruby on Rails 4, I'm trying to loop through my student list, and insert their ID's into the attendances table via a checkbox.

I'm getting the following error:

No route matches {:action=>"mark_attendance", :controller=>"attendance"} missing required keys: [:student_id, :attendance_id]

My files:

routes.rb

  resources :static
  resources :student do 
    resources :attendance
  end

  devise_for :users
  root :to => "static#index"

student_controller.rb

class StudentController < ApplicationController
    def index 
        @students = Student.all
    end

    def show 
        @student = Student.find(params[:id])
    end

    def create
        @student = Student.new(student_params)
        respond_to do |format|
            if @student.save
                format.html { redirect_to @student, notice: 'Student was successfully added.' }
                format.js
                format.json { render action: 'show', status: :created, location: @student }
            else
                format.html { render action: 'new' }
                format.json { render json: @student.errors, status: :unprocessable_entity }
            end
        end
    end

    def student_params
        params.require(:event).permit(:name, :contact, :balance)
    end 
end

student.rb

  has_and_belongs_to_many :attendances
  attr_accessible :name, :contact, :balance
end

attendance_controller.rb

class AttendanceController < ApplicationController
    def create
        @student = Student.new(attendee_params)
        respond_to do |format|
            if @student.save
                format.html { redirect_to @student, notice: 'Students were added successfully.' }
                format.js
                format.json { render action: 'show', status: :created, location: @student }
            else
                format.html { render action: 'new' }
                format.json { render json: @student.errors, status: :unprocessable_entity }
            end
        end
    end

    def mark_attendance

    end

    def attendee_params
        params.require(:event).permit(:student_id, :date)
    end 
end

attendance.rb

class Attendance < ActiveRecord::Base
  belongs_to :student
  attr_accessible :student_id, :date
end

index.html.erb

                        <% @students.each do |s| %>
                        <tr>
                            <td><%= check_box_tag "student_ids[]", s.id %></td>

                            <td><%= s.contact %></td>
                            <td><%= number_to_currency(s.balance) %></td>
                            <td><%= link_to "View", student_path(s.id), :class => "btn btn-primary" %></td>
                        </tr>
                        <% end %>
                    <% end %>
                </table>
            </div><!-- End Table Responsive -->
        </div><!-- End col-md-8 -->
        <div class="col-md-3"></div>
    </div>
</div><!-- End Row -->

I would love to know what the error is or how I would be able to do this using checkboxes.
