This wiki page is for the description of changes made under E1954. Auto-generate submission directory names based on assignment names for Fall 2019, CSC/ECE 517.
Expertiza Background
Expertiza is an educational web application created and maintained by the joint efforts of the students and the faculty at NCSU. It’s an open-source project developed on Ruby on Rails platform and its code is available on Github. It allows students to review each other’s work and improve their work upon this feedback.
Need of the current project
The following states the needs/issues with the current Expertiza project.
Whenever an instructor/TA adds a new Assignment with the name of already existing assignment in the same course, then the newly created assignment is stored in the same directory as that of the previously created assignment which creates a conflict. Thus, need of a check that should be added to prevent two assignments in the same course from having the same name.
Two assignments can currently be stored in the same directory. Thus, need of a check to stop two assignments from sharing the same directory.
The directory name is not auto-generated from the assignment name. Hence, auto generation is required.
Description of the current project
The following is an Expertiza based OSS project which deals primarily with the AssignmentsController and AssignmentsView - _general.html.erb. Here is the details description of the project:
The directory name is auto-generated from the assignment name. The instructor is allowed to edit
It is done by changing spaces in the names to underscores. E.g., the directory for Program 1 is by default "Program_1".
The special characters like '/','\','$' etc are to be removed from the auto-generated submission directory name.
A check is added to prevent two assignments in the same course from having the same name.
A check is made to stop two assignments from sharing the same directory.

Files modified in Project
A controllera, helper file and spec were modified for this project namely:
1. AssignmentsController
2. AssignmentsView - _general.html.erb
3. AssignemntsController - assignments_controller_spec.rb
AssignmentsController
This is a controller that helps instructors create, modify, copy new assignments. Each assignment can be associated with specific Rubrics, Review Strategy and Due dates.
AssignmentsView - _general.html.erb
This the View for creating the new assignments and editing the existing assignments. This view also handles specifications of Rubrics, Review Strategy and Dates.
List of changes
We worked on the following work items(WIs)
WI1: Created exist_assignment and exist_directory to check if the assignment name and directory name already exists in the current course. If any of those are already present then flash the respective error, else save the assignment. Here is the create method of controller -> assignments_controller.rb:
def create @assignment_form = AssignmentForm.new(assignment_form_params) if params[:button] # Do not create an assignment if the assignment name or directory name already present in the course exist_assignment = Assignment.find_by(name: @assignment_form.assignment.name, course_id: @assignment_form.assignment.course_id) dir_path = assignment_form_params[:assignment][:directory_path] exist_directory = Assignment.find_by(directory_path: dir_path, course_id: @assignment_form.assignment.course_id) if !exist_assignment and !exist_directory and @assignment_form.save @assignment_form.create_assignment_node current_assignment = Assignment.find_by(name: @assignment_form.assignment.name, course_id: @assignment_form.assignment.course_id) assignment_form_params[:assignment][:id] = current_assignment.id.to_s ques_array = assignment_form_params[:assignment_questionnaire] due_array = assignment_form_params[:due_date] ques_array.each do |cur_questionnaire| cur_questionnaire[:assignment_id] = current_assignment.id.to_s end due_array.each do |cur_due| cur_due[:parent_id] = current_assignment.id.to_s end assignment_form_params[:assignment_questionnaire] = ques_array assignment_form_params[:due_date] = due_array @assignment_form.update(assignment_form_params, current_user) aid = Assignment.find_by(name: @assignment_form.assignment.name, course_id: @assignment_form.assignment.course_id).id ExpertizaLogger.info "Assignment created: #{@assignment_form.as_json}" redirect_to edit_assignment_path aid undo_link("Assignment \"#{@assignment_form.assignment.name}\" has been created successfully. ") return else flash.now[:error] = "Failed to create an assignment. Kindly rename." render 'new' end else render 'new' undo_link("Assignment \"#{@assignment_form.assignment.name}\" has been created successfully. ") end end
WI2: Auto-generate the Submission directory name based on the assignment name. Allow, the Submission Directory name field to be explicitly editable by the instructor. Here is the javascript function introduced in views -> assignments -> edit -> _general.html.erb
<tr><div class="form-inline"> <td style='padding:5px'><%= label_tag('assignment_form[assignment][directory_path]', 'Submission directory:') %></td> <td style='padding:5px'><%= text_field_tag('assignment_form[assignment][directory_path]', @assignment_form.assignment.directory_path, required: true, :id => 'directory_field', :style => 'width:250px', class: 'form-control') %> (Note: Directory name is auto-generated from Assignment Name. You can change it if you wish to.) <img src="/assets/info.png" title='- DO NOT change this filed for an on-going assignment. This may cause lost of student submitted file.'> </td></div> </tr>
$(function() { $("#name_field").change(function() { filename = $( "#name_field" ).val().replace(/ /g,"_").replace(/[/\\?%*:|"<>/$&!#%^@]/g, '');; $('#directory_field').val(filename); }); });
WI3: Earlier the assignment was getting generated even if the instructor was not giving it any name or submission directory path, now both of these fields have been made mandatory.
Testing Plans
Testing plan is divided into two - Rspec testing and UI testing
1) RSpec Test plan
As the controller code has been changed now, which does not allows two assignment files to be stored with same name. Thus, in the spec file for assignments controller, a test case has been added for the same.
context 'when assignment_form is not saved successfully due to same assignment/auto generated directory exists' do it 'renders assignment#new page' do allow(Assignment).to receive(:find_by).with(name: 'test assignment', course_id: 1).and_return(assignment) allow(Assignment).to receive(:find_by).with(directory_path: 'test_assignment', course_id: 1).and_return(assignment) post :create, @params expect(flash.now[:error]).to eq("Failed to create an assignment. Kindly rename.") expect(response).to render_template(:new) end end
2) UI Testing
Following Steps needs to be performed to test the project from UI:-
Step 1: Login as Instructor (Username - instructor6, Password - password). Create an assignment under any of the existing courses with name as "test assignment".
Step 2: Check if the Submission directory field is automatically getting populated based on the assignment name (replacing spaces with underscores and removing special characters).
Step 3: Fill in the details for Rubrics and Review Strategy.
Step 4: Click on create. You should be able to see the assignment you created in the list.
<br
Step 5: Now, try to create another assignment with the same name in the same course. Also, try to change the submission directory name to any of the existing assignment or same the assignment created in Step 2, Check if the system flashes an error in the creation of this assignment.
