Problem Statement

E1960. Create new late policy successfully and fixing "Back" link

Background: An instructor can create late policies for any assignment, wherein the instructor can specify the points per unit and the maximum penalty that can be applied for any assignment submission.

Issue 1: If an instructor while creating a policy, clicks on “Create” (Step 5), following error message is displayed on the top of the page “The following error occurred while saving the penalty policy:” and the policy is not created and added to the list of policies.

Issue 2: If an instructor, while creating a policy, clicks on "Back" link (Step 6) and wants to go back to the previous page, (s)he is directed to the list of policies instead of “Due Date” tab of assignment edit page (Step 2 above).

Problems in Current Implementation

Problem 1: Failure to create a new policy The create button on the new page of late_policy is not working. Whenever the data for the form is filled and submitted by clicking on the Create button, an error message is shown saying “The following error occurred while saving the penalty policy:” and the policy is not created and added to the list of policies.

Problem 2: Back link redirects to the wrong page An instructor can choose to go back to the previous page from the create new policy page. When the Back button on the create new late policy is clicked, it should be redirected to the Due Date tab of the assignment it came from but it is redirected to the index page of late policies.

Solutions to Problems in Current Implementation

Problem 1: Failure to create a new policy

   Solution:
   There was no provision to handle the validations of the form in the new late_policy page.

Problem 2: Back link redirects to the wrong page An instructor can choose to go back to the previous page from the create new policy page. When Back button on the create new late policy is clicked, it should be redirected to the Due Date tab of the assignment it came from but it is redirected to the list of late policies page

   Solution: 
   We tried to store the assignment id of the page from where the create new policy was clicked. This way when we have to redirect after the back button, 
   we can send it to this particular assignment with the help of assignment id.

app/views/late_policies/new.html.erb

   <%= f.hidden_field :assign_id, value: params[:id] %>
   <%= link_to 'Back', :controller => 'assignments', :action => 'edit', :id => params[:id], :anchor => "tabs-5" %>

app/controllers/late_policies_controller.rb

   redirect_to action: 'index', id: params[:late_policy][:assign_id]

app/views/late_policies/index.html.erb

   <%= link_to 'New late policy', :action => 'new', :id => params[:id]%>

Back Case - 1

   Step 1: Click Back on Create New Policy page

   Step 2: Redirected to the Due Dates tab of the assignment page it came from

Back Case - 2

   Step 1: On Index Page of Late Policies. Click Create New Policy

   Step 2: Click Back

   Step 3: Redirected to the due dates tab of assignment page it came from
