View source for CSC/ECE 517 Fall 2019 - E1966. Tabbed reviews partial file refactor for displaying the alternate view of reviews

== '''About Expertiza''' ==

Expertiza is a open source project currently for CSC517 instructor and students forming groups, submit work, review, and view grades. The project is based on Ruby on Rails framework and the code is on Github: https://github.com/expertiza/expertiza. Expertiza serves wiki page, collecting information of all internal information and updates of all versions.

== '''Problem Statement''' ==
===Issue details===


1) On student end, Expertiza uses grades/_reviews.html.erb partial file to display reviewers, scores and review details; on instructor end, it uses Response model methods to construct html file for review pages. We need to use the same kinds of partials in instructor-end and student-end.

How to get the view of reviewers, scores and review details on student end? Click "Alternate View" button, and click "show reviews" link. The reviewers and scores pop up on the top and review details are below them.
How to get the view of reviewers, scores and review details on instructor end? Click "Scores" for a certain assignment and choose a team. Click "Statistics" tab and then reviewers and scores table show up. Click "Reviews" tab and then click one of students' name link in the table head. And a new page pops up with review details.

2) Give Feedback link at view_my_score at student-end should not appear at folded view.
Where to find Give Feedback link? On student end, click "Alternate View" button and click "show reviews" link. At the bottom of a certain review, a give feedback link shows up.

===What to do===
1) We need to use the same kinds of partials in instructor-end and student-end. So we decide to use  grades/_team_statistics.html.erb to display reviewers and scores and to use grades/_tabbed_reviews.html.erb to display review details for both student-end and instructor-end.

2) Give Feedback link at view_my_score should appear at the bottom of expanded view.

== '''Solution''' ==
For student end, split reviews.html.erb into two partial files. One is grades/team_review_statistics.html.erb for reviewers and scores. The other one is grades/tabbed_reviews.html.erb for review details.
For instructor end, it used to use response model methods to construct html files for review details, now we use grades/tabbed_reviews.html.erb to display review details.
So student end and instructor end both use grades/team_review_statistics and grades/tabbed_reviews to display reviewers, scores and review details.

===Student End===

* In student end, render grades/team_review_statistics and grades/tabbed_reviews two partial files instead of grades/reviews partial file.
'''app/views/grades/_participant.html.erb '''
<pre>
<TR id="<%= prefix %>_reviews" style="display:none; background-color: white;">
    <TD COLSPAN="10">
    <%= render :partial=>'grades/team_review_statistics', :locals => {:prefix => 'user', :participant => participant, :pscore => pscore} %>
    <%= render :partial=>'grades/tabbed_reviews', :locals => {:prefix => 'user', :participant => participant, :rscore => pscore[:review]} %>
    </TD>
</TR>
</pre>
* Add statistics view to student end by using the team_review_statistics.html.erb file.
'''app/views/grades/_participant.html.erb '''
<pre>

                        review_feedbacks = map.try :response %>
                    <% if review_feedbacks && !review_feedbacks.empty? %>
                        <%= link_to "View", :controller => 'response', :action => 'view', :id => review_feedbacks.first.id %> or
                        <%= link_to "Edit", :controller => 'response', :action => 'edit', :id => review_feedbacks.first.id, :return => "feedback" %> feedback for Review <%= count %>
                    <% else %>
                        <%= link_to "Give feedback", :controller => 'response', :action => 'new_feedback', :id => review.id %> for Review <%= count %>
                    <% end %>
                </td></tr>
    <% end %>

* Add javascript to tabbed review so it can be hidden or shown by clicking the show/hide reviews.

  };
  $( document ).ready(function() {
    $('#tag_prompt_toggler').click(function () {

        $('#tag_prompt_toggler').text("show tags")
      else
        $('#tag_prompt_toggler').text("hide tags")
    });
  });
</script>

=='''Test Plans'''==
*The rspec test plan is written such that each requirement(for student-end and instructor-end) will have at least 1 different test. 
*The test plan is also used as a check of bug fix implementation. It ensures that each required function is implemented and each bug is well fixed. 
*The test file can be manually executed the by running "rspec ./spec/features/tabbed_reviews_spec.rb" on rails terminal.
*We need use Unit test to test all the function mentioned above with respect to views, models and controllers.
