Topic Description

Backgroud

Expertiza is web application devloped on Ruby on Rails platform. It helps students to create reusable learning objects through peer review. It also supports document submission and team projects. Expertiza allows the instructors to import following data:

• A list of users.
• A list of participants for an existing assignment.
• A list of participants for an existing course.
• A list of teams for an existing assignment
• A list of teams for an existing course.
• A list of reviewer assignments.
• A list of meta-reviewer assignments.

These imports are done by uploading a file containing data. The data should be formatted as different rows represented as lines of text in the file. The rows should contain values separated using delimiters. There can be 4 types of delimiters:

1. Comma
2. Space
3. Tab
4. Other - Any custom delimiter provided by the user as text

Problem Statement

The following is an Expertiza based OSS project which deals primarily with the Import File controller. This project is associated with fixing issue #110 on the Expertiza Github. The problem with these imports is that they are not implemented consistently. There are restrictions to how the columns should be ordered in the import file. The aim of this project is to improve the import functionality as well as provide a flexible and user-friendly user-interface to the users so that they are able easily import users, participants, topics, etc.

Solution

To resolve this issue we have changed the interface and the import process to an extent, keeping the core methods of import intact with just few required minor changes. In the new interface, upon importing, the system would then display what was imported, and let the user choose from a dropdown which field was which. The default ordering is the same as what is currently required by Expertiza unless a specific order is provided by the user as a header in the import file.

Added Features

Files Changed

Assets

To implement the functionality of non-duplicate column names, we created two new methods checkIfUserColumnDuplicate() and checkIfParticipateColumnDuplicate() in the shared.js .

Config

We needed to change the routes.rb so that the new partial views can be implemented.

Controllers

For the enhancement of the import functionality, we modified the import_file_controller. In this controller, we modified one existing method import(), other than that we had to declare some additional methods import_from_hash(), hash_rows_with_headers(), parse_to_hash(), parse_to_grid() and show().

Helpers

As we changed the original implementation from array to hash we need to also modify the import_file_helper a little bit.

Models

There is a list of models we had to modify for enhancing the import functionality, which are listed below along with the original methods we needed to modify:

1. assignment_participant : self.import()
2. course_participant : self.import()
3. course_team : add_member()
4. metareview_response_map : self.import()
5. review_response_map : self.import()
6. team : import_team_members() and self.import()
7. user : self.import()

Views

To use the import functionality in a new and enhanced way, we modified one of the existing view and added new views, listed below:

Views Modified:

1. start.html.erb

Views Created:

1. _metareviewer.html.erb
2. _participant.html.erb
3. show.html.erb
4. _reviewer.html.erb
5. _team.html.erb
6. _user.html.erb
