@jaron42 A couple of style comments:

• Standard indent size for Python is 4 spaces. Looks like you have some 2's in there, probably because you are using Nano and can't conveniently indent/unindent a block of lines. (Not trying to nitpick the formatting; trying to convince you you would be happier using a more capable editor.)
• You could conveniently use slice notation here (in a couple of places):

Instead of this (file piservice/views.py, lines 1021, 1568):

"return_guidance_pattern": [params[0], params[1], params[2], params[3], params[4], params[5]],

You could do this:

"return_guidance_pattern": params[0:6],

or in this case you could also do just:

"return_guidance_pattern": params,
