CSC/ECE 517 Fall 2017/E17A5 Allow users to create an account and submit work to an "assignment" (e.g., for conference reviewing)

Problem Definition

Expertiza is mainly a peer-assessment system for the students to review submissions made by their peers. For a similar system for journals and conferences, there is one stark difference from the standard peer assessment system. For journals and papers, we need to allow the user to create an account to submit the paper, unlike the standard system where the instructor is supposed to create account for all the students. Also, when a user wants to add a co-author for his/her paper/submission, he should be able to invite them irrespective of the fact that the invited user has an account or not. If the invited user does not have an account, a new account must be created for him/her. For the new system, submitting and reviewing is same as the peer assessment system.

Scope

This project aims at extending the application of the expertiza system towards reviewing of journals and conferences by peer authors and relevant users. Hence, it enhances the utility of the expertiza platform for better knowledge sharing beyond the simple assignment submission and reviewing.

Requirements

1. Any non-Expertiza user can sign up, for submitting his/her work

2. Document upload privileges for that user.

3. Adding co-authors to a paper being submitted for reviewing.

4. View for scores/reviews submitted by reviewers.

Use Cases

Primary Sequence:

1. Go to Conference Reviewing section

2. Provide information in form for sign up

3. Activate account by opening link, provided via e-mail

Name: Add contributors

Actor: Writer

Other Participants: None

3. The writer is redirected to an upload page where the user can upload the submission.

Name: Upload Paper

Precondition: The writer has already created a submission window and is at the upload page.

Primary Sequence:

1. The writer clicks the “Upload paper”button.

2. The writer selects the paper to be submitted from local device.

3. The writer clicks the “Submit” button.

Database Design

Table to handle many to many relationship between contributors and paper writer.

The project uses mainly uses the same database of the actual expertiza system. The tables need to be edited by adding some attributes to provide sufficiemnt relations among the system.

1. The table assignments that stores the submissions need to have a new attribute that can distinguish if the submission is a paper or not.

2. The roles table identifies all different types of users that access expertiza system like instructor, students, etc. We need to add two more roles to this table, the writer and his co-writers.

3.

Class Diagram

Files to be created

1. new_writer_signup.html.erb : /app/views/users/

Needed to allow the author/writer of paper to signup to expertiza. As signup is not part of the current system, this needs to be explicitly created.

2. writer_homepage.html.erb :

This is the homepage of the writer. He can view his submissions and access the functionalities available to him.

3. add_coauthors.html.erb :

This file is needed to allow the writer to invite co-authors for his/her paper. The writer enters the details of the co-author to be invited in this page.

4. writer_paper_mapping.rb :

This is the model needed to map the papers to their authors. As papers and writers have a many to many relation, it needs to be handled by this model.

Files to be edited

1. users_controller.rb

2. assignments_controller.rb

Implementation

So far we have been able to make a writer sign-up to the expertiza platform. The following code snippets are used for the same.

View:

    <%= form_for @user , :url => url_for(:controller => 'users', :action => 'create_writer') do |f|%>
        <%= f.label :name %>
        <%= f.text_field :name %>
        <%= f.label :email %>
        <%= f.text_field :email %>
        <%= f.label :password %>
        <%= f.text_field :crypted_password %>
        <%=submit_tag "Create Writer"%>
    <%end%>

Controller:

    def new_writer
      @user = User.new
      render 'new_writer_signup.html.erb'
    end

Model:

    def create_writer
      @user = User.new(user_params)
      @user.role_id = 8;
      @user.is_new_user = 1;
      if @user.save
        flash[:success] = "Your account has been successfully created"
        render 'new_writer_signup.html.erb'
      else
        render 'new_writer_signup.html.erb'
      end
    end

Designing Practices

The designing practices used will be determined as the project proceeds and the requirements are handled. But for starting the project we will be following the following standard design practices:

1. Model-View-Controller architecture

2. Using standard naming convention for variables and methods, like name_variable, singular words for class name, etc.

3. Try not to violate DRY principle
