CSC/ECE 517 Fall 2016 E1655/OSS Improve e-mail notification
Peer Review Information
For users intending to view the deployed Expertiza associated with this assignment, the credentials are as follows:
- Instructor Login: Username: instructor6 , password: password
- Student Login: Username: student5432 , password: password
We would request you to create at least 3-4 users more to test all the functionality pertaining to this project. This is because teams can be created and all the functionality with respect to email notifications can be tested.
Expertiza Background
Expertiza is an open-source project based on Ruby on Rails framework. Expertiza allows the instructor to create and customize new or existing assignments and courses. It also allows the instructor to create a list of topics the students can sign up for, add users, add reviewers, add teams. Students can form teams in Expertiza to work on various projects and assignments. Students can also peer review other student's submissions. Expertiza supports submission across various document types, including the URLs and wiki pages.
Mailers in Expertiza have their association with many other components like Users, Courses, Reviews, Participants and Invitations. The Mailer Helper in specific invokes methods which perform mailer related functions like sending email to newly created user, sending email to reviewer etc.
Motivation
This project in particular intends that the students collaborate and work on making enhancements to the code base by applying the concepts of Rails, RSpec, DRY code,Test driven development etc. This provides an opportunity for students to contribute to an open source project and learn further about software deployment etc.
Currently, the mailer notifies the students on their account creation and to the reviewer when a submission of work is done. The scope of this project is to improve the present email notifications and also plug gaps in some implementations.
Current Implementation
1. When students' accounts are created by importing a CSV file on the Users page, they receive e-mails with their user-ID and password. But if an account is created by adding them as participants to an assignment when they don't already have an account, e-mail is not sent. So, this issue is fixed by implementing the functionality of sending e-mail when account creation is done in this case. Now, e-mail is getting triggered to the concerned user whenever their account is created regardless of how their account is created. The listed files were manipulated for updating this functionality.
- controllers/import_file_controller.rb
- helpers/import_file_helper
2. Evidently, if a file is revised after review, the system e-mails the reviewer saying to revise the review. The method to implement this was in place but wasn't working. This issue is fixed. Note that the e-mail is only triggered for a file submission and there is no mailer functionality in place for URL submission. Also, after the last round of review is completed, e-mail is no longer is getting triggered as desired. The listed files were updated or created to get the functionality working.
- controllers/submitted_content_controller
- helpers/mailer_helper
- app/views/mailer/partials/_file_submission_plain.html.erb
- app/views/mailer/partials/_file_submission_html.html.erb
3. The message body of the e-mail now includes the round of the review stage for which the review is provided along with a link to the site. Files changed are same as mentioned in second point.
4.1 E-mail is triggered to an invitee whenever a participant sends out an invitation to another participant to join a team. The listed files were updated or created to get the functionality working.
- controllers/invitation_controller
- helpers/participants_helper
- app/views/mailer/partials/_team_join_invite_html.html.erb
- app/views/mailer/partials/_team_join_invite_plain.html.erb
4.2 Whenever the invitee accepts the invitation, the student who issued the invitation gets a mail stating that the invitee has accepted his/her invitation. The controller and helper class are same as mentioned in the 4th point. New views are created for this functionality
- app/views/mailer/partials/_team_accept_invite_html.html.erb
- app/views/mailer/partials/_team_accept_invite_plain.html.erb
5. Mail is also getting triggered when a student responds to a teammate advertisement. The controller and helper class changed are same as mentioned in the 4th point. New views are created for this functionality.
- app/views/mailer/partials/_response_to_advertisement.html.erb
- app/views/mailer/partials/_response_to_advertisement.html.erb

About import_file_controller
This controller derives from the Application Controller. It states the functionality of importing any kind of file like csv, xls, doc into the application. It defines the import function which takes the 'session' and 'params' as output and provides success message on successful import. It also provides the functionality of specifying the delimiter in the file which is being imported. The ImportFile method defined in the controller reads the file row by row based on the model concerned.

It provides functionality to download, create folder and delete folder after submission. It provides the functionality for submitting links and submitting hyperlinks separately.
prepared_mail = MailerHelper.send_mail_to_reviewer(User.find(participant.user_id), "A new submission is available", "file_submission", "file submission", Assignment.find(participant.parent_id).name) prepared_mail.deliver
About invitation_controller
This controller also derives from the Application Controller. It states the CRUD as well as other basic operations when an invitation is sent by an user to any participant to join their team.

def self.create_new_user(attributes, session) user = User.new(attributes) user.parent_id = (session[:user]).id user.timezonepref = User.find(user.parent_id).timezonepref user.save! prepared_mail = MailerHelper.send_mail_to_user(user, "Your Expertiza account and password have been created.", "user_welcome", user.password) prepared_mail.deliver user end
About participants_helper

Mailer.sync_message ({

Testing Details
UI testing of participant addition via CSV file and e-mail delivery check
- Login as instructor. Create a new course and assignment.
- Add new participant not having expertiza account to an assignment using a import file option.
- An e-mail is triggered for participant who do not have an expertiza account.
UI testing of file submission
- Login as student. Go to assignment and open your work page.
- Upload a new file submission. If the submission is made in review stage, an e-mail is sent to a reviewer saying a new submission is available for a particular review round. Thus, the reviewer will be able to see the review round number.
UI testing for sending/accepting invitation to join team
- Login as student. Go to assignment and open your team page.
- Search for a student with whom you want to team up and click on send invite. An e-mail is getting triggered to that student saying a new invite has been sent.
- When the other student accepts it, another e-mail is triggered back to the invitee saying the invite has been accepted.
UI testing for response to an advertisement
- Login as student. Go to assignment page.
- Go to your team and create an advertisement for this assignment.
- Login as some other student who is the participant of the same assignment. Go to assignment page and open sign up sheet.
- For the topic assigned to the student who created advertisement, an icon will appear in advertisement tab.
- Clicking on this icon will redirect the student to page where student can request to join the team of students who created advertisement.
- On click of request button, an e-mail of this response to the advertisement will be sent to the students who created advertisement.
Scope for Future Improvement
- An e-mail is being triggered only when a file is submitted for revision. But on the submission of a link, no such e-mail is sent. So, this is one of the areas which can be improved in the future.
