/taskId PUT failure

[unicornsleuth]

Describe the bug A PUT request fails to update, because of a bug in the code - expects 3 positional arguments, but receives 4 After I quickly/temporarily made this fix, I found that a PUT (and also patch, delete) does not invalidate the particular cache for that task.

To Reproduce Steps to reproduce the behavior:

1. In VSCode, run the Azure functions
2. In Postman, run a GET on http://localhost:7071/api/users/1/tasks
3. Take the first taskId you see (for me, it was 2) and run a GET on http://localhost:7071/users/1/tasks/2
4. Create a PUT request on http://localhost:7071/users/1/tasks/2 with the raw body:

   {
   "title": "title",
   "description": "description",
   "dueDate": "03/04/21 12:12:12",
   "completed": "0",
   "completedDate": "04/04/21 12:12:12"
   }

5. See error

Expected behavior You should see "Error: update() takes 3 positional arguments but 4 were given"

Screenshots If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Windows
• VSCode
• Postman

To Reproduce 2nd Part

1. You can easily fix this bug by removing the ",r" from line 308 of the /taskId init file
2. Save & reload functions
3. Run the PUT request from before (step 4)
4. Run the GET request from before (step 3) and see that the data has not been updated
5. Check in VSCode, and see that the output says "Cache cleared" AND "Returned data from cache"
6. Run the GET request from before (step 2) and see that the data has, in fact, been updated.

Additional context We should have a cache for each task that has been queried, of the form "users:{userId}:tasks:{taskId}" The caches are being created for these, but they are not being cleared when PUT/PATCH/DELETE is run on the task. The code needs to be reworked to invalidate those particular caches as well as the "users:{userId}:tasks" cache on each update.

How to Test :

• Open project in VS Code
• Click on the debugger icon on the left hand side tool bar in VS Code
• Set up environment for testing using python pathway
• Run the Azure functions In VS Code (Terminal should open and show logs and URL links for testing of functions)
• Open PostMan and paste URL links to functions and make GET for userId taskId request to cache
• Check Redis Server Cache for saved data

• Run DELETE request and refresh Cache and the data should be deleted. Same with PUT Request

  Description: Fixed the parameter bug in the PUT method. Took r (redis conneciton) out of the PUT method parameters. Solving the issue. Fixed the delete cache issue by changing the parameters in the invalidate function. Added the parameters key, userId, and taskId. Added the function call in the main where the PUT and DELETE functions are called.
