This wiki page describes the changes made according to the specification of E1781 OSS assignment for Fall 2017.

Peer Review Information

For testing the changes made, the following credentials are recommended:

  • Instructor Login: username: instructor6 password: password

This project does compile. Reviewers can refer Testing Plan: Testing from the UI and the YouTube link for navigation help.


The testing plan is at the end of this document. Design principles were not needed since we mostly modified existing work.

Introduction

Background

Expertiza is a web portal which can be used to manage assignments related to a course. It provides a platform to view assignments, manage teams, select topics and work improvement through anonymous peer reviews.

The instructor are allowed to define different topics that students or teams could choose from as their assignment. Each topic can have 0 or more slots that indicate the number of students or teams that can sign up for that topic. We identified several ideas that can improve user experience when managing the topics. Thus, we would like you to introduce new features to implement these ideas.

Problem Statement

The following were the tasks identified to be accomplished through this project.

  • Issue #971: Change create topic UI into AJAX
  • Issue #926: We need a way to sort topics by topic number in assignment#edit page
  • Issue #718: We should allow instructors to give feedback when accepting or rejecting topic suggestions

Issue #971: Change create topic UI into AJAX

Currently, when instructors manually enter topics, they have to go back and forth between the list of the topic page (views>sign_up_sheet>_add_signup_topics.html.erb) and the create topic page(views>sign_up_sheet>new.html.erb). Adding a new topic can be done through an editable grid (see js-grid) without leaving the list of topic page, by making use of AJAX. The list should be automatically updated when a new topic is entered. To enable AJAX the sign_up_sheet_controller.rb is modified so that it renders JSON to handle the javascript table/form.

In addition, when adding a topic, the default slot is set as 1 instead of 0. The current warning message that shows up when the slot is 0, has been fixed to close properly.


On the controller app/controllers/sign_up_sheet_controller.rb we edited the Load_add_signup_topics, which was converted from a function into a Rest endpoint(Json).

  def load_add_signup_topics
   @id = params[:id]
   assignment_id =  params[:id]
   @sign_up_topics = SignUpTopic.where('assignment_id = ?', assignment_id)
   @slots_filled = SignUpTopic.find_slots_filled(assignment_id)
   @slots_waitlisted = SignUpTopic.find_slots_waitlisted(assignment_id)
   @assignment = Assignment.find(assignment_id)
   @participants = SignedUpTeam.find_team_participants(assignment_id)
   # colloborating for JSON
   @sign_up_topics.each {|topic|
   topic_id = topic.id
   slots_fill_temp = 0
   slots_waitlisted = 0
   participants = []
   if @slots_filled 
     @slots_filled.each {|slot| 
       if slot.topic_id == topic_id
         slots_fill_temp = slot.count
       end
     }
   end
   if @slots_waitlisted 
     @slots_waitlisted.each {|slot| 
       if slot.topic_id == topic_id
         slots_waitlisted = slot.count
       end
     }
   end
   if @participants 
     @participants.each {|participant| 
       if participant.topic_id == topic_id
          
         participants << participant
       end
     }
   end
   topic.slots_filled_value = slots_fill_temp
   topic.slots_waitlisted = slots_waitlisted
   topic.slots_available = topic.max_choosers - topic.slots_filled_value
   topic.partipants = participants
  }
   render :json => {
       :id => @id.as_json,
       :sign_up_topics => @sign_up_topics.as_json( :methods => [:slots_filled_value,:slots_waitlisted,:slots_available,:partipants]),
       :slots_waitlisted => @slots_waitlisted.as_json,
       :assignment => @assignment.as_json
     }
 end

An Example output of the Json rendered for Assignment Id : 843 by the load_add_signup_topics Action is as follows

{ "id": "843", "sign_up_topics": [ { "id": 3958, "topic_name": "Power consumption issue", "assignment_id": 843, "max_choosers": 3, "category": "", "topic_identifier": "1.1.1", "micropayment": 0, "private_to": null, "description": null, "link": null, "slots_filled_value": 0, "slots_waitlisted": 0, "slots_available": 3, "partipants": [] }, { "id": 3959, "topic_name": "Perspectives on parallel computers (1.4 in old edition)", "assignment_id": 843, "max_choosers": 2, "category": "", ... (And so on.)


Similarly, We have changed all the actions/methods (destroy|setup_new_topic|update_existing_topic|update|set_values_for_new_topic ) to render Json rather than rendering a view, In order to satisty our Ajax requirements in the front end.


On the model app/models/sign_up_topic.rb we have creates attribute accessor for variables to set properties that are required for JSON.

 attr_accessor :slots_filled_value
 attr_accessor :slots_waitlisted
 attr_accessor :slots_available
 attr_accessor :partipants

On the View 'app/views/sign_up_sheet/_add_signup_topics.html.erb' we have just added the following

<%= content_tag :div, id: "jsGrid", data: { assignmentid: @assignment.id }  do %>
<% end %>

The contents of the above tag is completely rendered via Javascript, where we use JSGrid for dynamically allowing users to Add, Delete and Update Topics on the same page.

               jQuery("#jsGrid").jsGrid({  
               width: "100%",

The Preview View for Topics Management :

After Our Implementation using JS Grids :

Issue #926:

This task is to do with sorting the Topics according to the topic number. This functionality is taken care by Js-Grid by itself, where clicking the topic# will toggle the topics in the ascending/descending order.

Sorting in Ascending Order:

Sorting in Descending Order :

Issue #718:

Instructors should be allowed to give feedback when accepting or rejecting topic suggestions. Earlier, feedback on topics suggested by students can be given only when the instructor wants the topic to be revised, not when (s)he is approving or rejecting it. Feedback should be possible in any of these cases.

In app/controllers/suggestion_controller.rb

Including the text provided in the comment field, while approving the topic.

      <%= submit_tag "Approve suggestion", :name => 'approve_suggestion' %>
         
      <%= submit_tag "Reject suggestion", :name => 'reject_suggestion' %>

Testing Plan: Testing from the UI

UI Testing

The majority of the changes can be tested via the UI. Follow the instructions below to check the tasks:

  • Issue #971: Change create topic UI into AJAX
  1. Login as an instructor. It will automatically go to the manage courses page
  2. Click Assignments tab next to Courses
  3. Select the assignment for which a new topic has to be added
  4. Click the edit icon for the assignment and go to Topics tab
  5. You will be able to see the topics list in a grid format. Click on add icon on the right side corner of the grid
  6. You can also edit an existing entry by just clicking on that row in the grid without being redirected to a new page
  • Issue #926: Sort topics by topic number in assignment#edit page.
  1. Log in as any user or instructor.
  2. Go to the assignments list. Note: this is not the manage assignments for instructors.
  3. Click into a finished assignment. You will notice the actions column is gone.
  4. Click into a current assignment. You will notice the actions column appears.
  • Issue #718:
  1. Login as an instructor. It will automatically go to the manage courses page.
  2. Click on the "Manage Notifications" link above the "Courses" and "Assignments" links. Note: The link was placed here because the system has numerous issues when adding menu items. It would require us to do more work that the entirety of this project to correct the menu additions in the superuser menu.
  3. You will be directed to a creation page for notifications. Note: in order for a notification to display the expiration date must be the current date or later, and the active checkbox must be selected.
  4. Log out once the notification is created.
  5. Log in using any account. The notification will display on the first page the user is shown. It will disappear when they change or reload the page. Note: instructors on the management page will retain the notification if they switch between Assignments, Courses, and Questionnaires. This is because the JavaScript does not actually reload the page.
