Assignment suggestions using Tabea's PRA solver

[charludo]

Short description

The "suggest assignment" button finally works! 🥳 🎉

Proposed changes

• add management command for exporting ward patients to Tabea's format, using her solver, and returning the solution
• clicking the "suggest assignment" button takes you to the normal timeline view, with the option to save, cancel, or edit the timeline as usual

Please Note

• 93 should be merged BEFORE this, so if you want to review this PR, please instead review that one 😉

• the bed assignments aren't exactly ideal, but this is not on us. Not sure if there is an error in the solver, or if it is just due to the rounding. We will have to wait and see how it works with the final presentation data; before then, there isn't really anything we can do with this.
• this does not work for Pädiatrie, because the solver cannot handle rooms with more than 2 beds (see error in console)

Installation

• clone TabeaBrandt/patient-to-room_assignment next to where your copy of ycms lives
• inside patient-to-room_assignment, do
  • python -m venv .venv
  • . .venv/bin/activate
  • pip install gurobipy

Resolved issues

Fixes: #20

A doubt: I am on the branch automatic-assignment So I installed patient-to-room_assignment in the same directory as ycms. I installed gurobi in the same virtual environment as rest of the project (its called denv). I run ycms and click on suggest assignment but nothing seems to pop up, What am i missing?

Please follow the instructions as given:

• inside patient-to-room_assignment, do
  • python -m venv .venv
  • . .venv/bin/activate

"next to" means that the two are "siblings". For example,

/home/sneha/ycms/
/home/sneha/patient-to-room_assignment

but not

/home/sneha/ycms/
/home/sneha/ycms/patient-to-room_assignment

(its called denv)

I am really not sure how that works, the install.sh script handles virtual environments in our project, and it will always be located in .venv.

In any case, you need a separate one, as the instructions say.

Yup they are siblings.

I had created a virtual env denv in the begining where I installed everything in ycms. I followed the instructions also and added venv inside patient-to-room directory. and then I went back to ycms and ran it. clicking on suggest assignment didn't do anything for me. Am I supposed to directly click on that or I check in timetravel for assignments and then it will show

Alright, what's the console output when you click the button? And no, should not matter which one.

Actually, could you please also provide the output of pwd and ls -al from inside the solver directory?

A more direct way for trouble shooting could also be using ./tools/ycms-cli call_solver_api 1, since this is what the ward/timeline views call

So when I click on the button I get the following output:

Console shows this :

So the main directory is hosproj under in which both ycms and pra reside.

From the console error output: looks like you need a (free) license. Interesting. I got one but thought it's activation failed, but apparently not!

Have a look online, the license is pretty easy to get.

Works for me👌👌. I can see suggested assignments for unassigned patients in the timeline view for past current and future. Do you want to wait till the final data before merging this?

Great! And no, let's merge if you've no change requests.
