.save() should handle INSERT and UPDATE depending on situation.

[IVIyg0t]

Describe the bug
Model.save() should handle both INSERT and UPDATE situations.

To Reproduce
Steps to reproduce the behavior:

from models.Post import Post

# Create an empty model
post = Post()

# Populate fields
post.title = "Some Title"
post.content = "Some Content"

# Save post (should INSERT)
post.save()

Expected behavior
.save() should create a new record if it doesn't exist, otherwise update.
