CSC/ECE 517 Fall 2020 - E2056 Account Request Controller.rb

This wiki page is for the description of E2056. Remove multiple topics at a time.

Introduction

The Expertiza project is software to create reusable learning objects through peer review. It also supports team projects, and the submission of almost any document type, including URLs and wiki.

Problem Statement

Expertiza has Assignment objects, which represent an assignment that is done by some number of users. For some assignments, students need to select a topic before submitting work.

Topics associated with an assignment be reached as follows:

1. Log in as an instructor or a TA.

2. Select Manage->Assignments, which will bring up a list of assignments.

3. Click on “edit logo” under the “Action” column of an assignment.

4. Click on “Topics” tab in edit assignment page.

If an instructor or a TA wants to delete topics, he has to delete one topic at a time and has to wait for the page to refresh and then (s)he can proceed to delete the next topic, topics can only be deleted one by one.

To fix the problem:

1.There should be a checkbox column, along with other columns in “Topics” tab, where a user can select the topics (s)he wants to delete.

2.There should be a delete button/link at the end of the topic table with the name “delete selected topics” to delete the selected topics after a confirmation, prompted post clicking the button/link.

3.There should be a button/link alongside “delete selected topics” by the name “Select all” so that a user can select all and delete them in one go after clicking on “delete selected topics”.

How to manually test our function

1. Beside "Home", click "Manage...", then click "Assignments".

2. Choose an Assignment ( Final project (and design doc) is recommended).Then click "Edit" below Actions.

3. Click "Topic" tab.

4. Create some topics by click "New topic" on the bottom line.

5. Select them and click "Delete selected topics". Then click "Yes". (It may take a while!)

6. Then you shall see they are deleted. (For some reason we don't know, it failed when editing a staggered deadline assignment.)

Solution

1. Create User Requested Record

The function is designed to receive the information of the User who seeks the permission to access the website. The information is saved into the AccountRequest Model. The task was to split the function into different methods due to it being too verbose or write comments into the code. We chose to add comments into the function as splitting up would be inefficient.

2. Splitting up the Views

The task was to design a logic to the existing code such that the administrator would be able to see requests in two different views as in 'Under Review' or 'Approved/Rejected'. An additional function 'list_pending_request_finalized' was added that would filter the requests into 'Approved/Rejected' and the original 'list_pending_request' that filters the requests with 'Under Review' status. By default the requests are ordered in descending order with respect to updated_time with the status - 'Under Review'.

3.'Delete' function

File: app/controllers/sign_up_sheet_controller.rb

It defines the following functions:

delete_all_selected_topics : This function deletes all the selected topics

load_all_selected_topics : This function loads all the rows ( tuples ) from sign up topics which have the mentioned topic ids.

  
def delete_all_selected_topics
    load_all_selected_topics
    @stopics.each(&:destroy)
    flash[:success] = "All selected topics have been deleted successfully."
    respond_to do |format|
      format.html { redirect_to edit_assignment_path(params[:assignment_id]) + "#tabs-2"}
      format.js {}
    end
  end  
  def load_all_selected_topics
    @stopics = SignUpTopic.where(assignment_id: params[:assignment_id], topic_identifier: params[:topic_ids])
  end

File: config/routes.rb

Add url.

  post :delete_all_selected_topics

Result

We can see that we have a check-box coloumn in the table. We also have a 'Select All' option at the end of the table.

We can select a few topics in the table by clicking on the appropriate check-box

We can select all topics in the table by clicking on the 'Select All' option

When we click on the 'Delete Selected Topics' button , we get a popup asking for conformation.

Test

File: spec/controllers/sign_up_sheet_controller_spec.rb

Select assignment with id '834' and topic with id ['E1732'] as params. Post params to delete_all_selected_topics. Expect success flash with 'All selected topics have been deleted successfully.' and redirect to '/assignments/834/edit#tabs-2'.

  describe '#delete_all_selected_topics' do
    it 'delete_all_selected_topics and redirects to edit assignment page' do
      allow(SignUpTopic).to receive(:find).with(assignment_id: '834',topic_identifier: ['E1732']).and_return(topic)
      params = {assignment_id: 834, idents: ['E1732']}
      post :delete_all_selected_topics, params
      expect(flash[:success]).to eq('All selected topics have been deleted successfully.')
      expect(response).to redirect_to('/assignments/834/edit#tabs-2')
    end
  end
