Database (#25)

* successfully added data to database, test successful, renamed model file

* Added instructor CRUD

* minor changes, added parent's name for student

* added parents

* moved over from test database, added testing

* testing change env to repo secrets

* hopefully this fixes env error

* rectifying secrets issue

* let's try again

* test print

* what about now

* so butter fingers today

* try harder

* let's try another way

* let's see what's the error

* 6th diff error?

* json formatting error?

* hmmmmmm

* huh

* test nth

* Fixing github treating {} as secrets try 1

* Fixing github treating {} as secrets try 2

* try with encrypt/decrypt instead

* chmod +x using git, will it work?

* forgot abt this

* silly me

* what if chmod in workflow

* hmmm identifying new error

* changed file path

* changed file path in database code, omg workflow finally proceeded

* changed 1 path and forgot the others lmaopain

* removing potential error to see if that's the error

* swapping env code over

* try again

* lets try this

* reverting some changes to see progress

* removing testing for test database
