This wiki page is for the description of changes made under E1843- Issues Related to Topic Deadlines OSS assignment for Fall 2018, CSC/ECE 517.


About Expertiza

Expertiza is an open source project based on Ruby on Rails framework and the code is available on Github. Expertiza allows the instructor to create new assignments as well as edit new or existing assignments. Instructors can also create a list of topics the students can sign up for and specify deadlines for completion of various tasks. Students can form teams in Expertiza to work on various projects and assignments as well as peer review other students' submissions. Expertiza supports submission across various document types, including the URLs Wiki pages.


Issues in the Current Project

1.There is no deadline that specifies when a team can drop their topics. Due to this, few problems occur: The team might drop a topic later on which is close to the submission date and this results in topic not being assigned to any other team on time such that they can submit their assignment. Also, if one team was wait listed for the same topic which the other team dropped closer to the submission deadline, then the first wait-listed team will be assigned to the dropped topic which is not desirable as they might be working on their assigned topic for long time.

2.There are different topics on which students can work during different times. This type of assignment is known as Staggered- deadline assignment in which different topics have different submission and review deadlines. For these assignments too, there is a need for "Drop Topics Deadline". In the current implementation, the drop topic deadline is same for all the topics in a Staggered Deadline assignment which is not desirable.

Corrections made in the New Project

1. The instructor can specify a Drop Topic deadline date now. After a drop topic deadline passes, the "X"(signup option) in the Sign-Up sheet disables so that the student cannot drop the topic and the wait-list for that topic is cleared, which will resolve the issue of the topic being assigned to a wait-listed team very close to the submission deadline.

2. Staggered deadline assignments now have different drop deadlines for different topics in that assignment.The above resolution also works for Staggered Deadlines Assignment

Files modified in Current Project

1. app/controllers/assignments_controller.rb

2. app/controllers/sign_up_sheet_controller.rb

3. app/models/student_task.rb

4. app/views/assignments/edit.html.erb

5. app/views/sign_up_sheet/_add_signup_topics_staggered.html.erb

6. app/views/sign_up_sheet/_due_dates.html.erb

Current Implementation

1. Clearing the waitlist after Drop Deadline passes is implemented in sign_up_sheet_controller.rb where it is checked if the current time is greater than the time mentioned in Drop deadline. If the deadline has been passed, the 'update_is_waitlisted' method of SignedUpTeam model is called to delete all the waitlisted teams for that topic. 2. Changes are made in Assignments View to add an additional column for Drop-Topic Deadline for Staggered Deadlines Assignment. The code snippets for corresponding changes in controllers and models are as below:

(i) app/controllers/sign_up_sheet_controller.rb

   if !topic_id1.nil? and !@drop_topic_deadline1.nil? and Time.now > @drop_topic_deadline1.due_at
   SignedUpTeam.update_is_waitlisted(topic_id1.topic_id,team_id) end


(ii) The 'update_is_waitlisted' method is implemented in app/models/signed_up_team.rb as follows:

    def self.update_is_waitlisted(topic_i)
    topic_id1 = SignedUpTeam.where(team_id: team_id).first
    if @assignment.staggered_deadline?
    @drop_topic_deadline1 = TopicDueDate.where(parent_id: topic_id1.topic_id, deadline_type_id: 6).first rescue nil end
    due_dates = params[:due_date]
    topics = SignUpTopic.where(assignment_id: params[:assignment_id])
    review_rounds = assignment.num_review_rounds
    topics.each_with_index do |topic, index|
    for i in 1..review_rounds
        @topic_drop_topic_due_date = due_dates[topics[index].id.to_s + '_drop_topic_' + i.to_s + '_due_date']
        if assignment.due_dates.select {|due_date| due_date.deadline_type_id == 6 }.nil?
        @assignment_drop_topic_due_date = DateTime.parse(@assignment_drop_topic_due_dates[i - 1].due_at.to_s).strftime("%Y-%m-%d %H:%M")
    end
    end

(iii) app/helpers/sign_up_sheet_helper.rb

     if assignment_due_dates.length == 0
        assignment_due_dates = @assignment_submission_due_dates
     end

(iv) app/models/student_task.rb

    def self.get_due_date_data(assignment, timeline_list, participant)
    if assignment.staggered_deadline?
       team_id = participant.team.try(:id)
       topic_id1 = SignedUpTeam.where(team_id: team_id).first
       if !topic_id1.nil?
          topic_due_date = TopicDueDate.where(parent_id: topic_id1.topic_id, deadline_type_id: 6).first rescue nil
          timeline = {label: ('Drop Topic Deadline').humanize}
          timeline[:updated_at] = topic_due_date.due_at.strftime('%a, %d %b %Y %H:%M')
          timeline_list << timeline
       end
    end
    assignment.due_dates.each do |dd|
    timeline = {label: (dd.deadline_type.name + ' Deadline').humanize}
    unless dd.due_at.nil?
          timeline[:updated_at] = dd.due_at.strftime('%a, %d %b %Y %H:%M')
          timeline_list << timeline
    end
    end
    end

Test Plan

It was discussed that project does not require any Unit Test cases to be implemented as the changes are mostly visible in views.
