AssertionError: No such polymorphic_identity 'simple' is defined

When a simple log is added to the database, /get/log no longer works. Here is the server error:

127.0.0.1 - - [01/Dec/2019 22:38:12] "POST /get/log HTTP/1.1" 500 -

NameError: name 'UNAUTHORIZED' is not defined

When testing something on my end, I discovered server error when the user tries to access an API (specifically /get/data) without being logged in

127.0.0.1 - - [01/Dec/2019 18:21:17] "POST /get/data HTTP/1.1" 500 -
Traceback (most recent call last):
...
  File "/Users/fred/Development/UH-backend/config/auth.py", line 12, in dec
    return UNAUTHORIZED
NameError: name 'UNAUTHORIZED' is not defined

Backend TODO

Here are some things that I thought of that we need to do (I will update it when I think of more)

  • Search patient by phone number
  • Medicines API (patient's medicine table, get medicines API, give medicine API)
  • Medicine remove or date range functionality (historical vs current)
  • Medicine reminder API
  • Illnesses Data API (add)
  • Illnesses Data API (get historical data)
  • New registration form

Table Information Duplication

In the log table and medicine table, we have columns for doctors' names and patients' names. We shouldn't do this! If the doctor or patient changes their name, then the table becomes out of date.
