Subject and session loading Admin

[antoinefalisse]

@olehkorkh-planeks do you have any thoughts?

When logged-in as admin, the web app is lagging because it tries to load data from all session/subjects belonging to all opencap users.

This is related to these lines on the api side:

• sessions: https://github.com/stanfordnmbl/opencap-api/blob/main/mcserver/views.py#L166
• subjects: https://github.com/stanfordnmbl/opencap-api/blob/main/mcserver/views.py#L1668

Having access to all sessions/subjects is however needed on the core side, because we "run" core using the admin token and need to retrieve session info and subject info from the trial being processed:

• sessions: https://github.com/stanfordnmbl/opencap-core/blob/main/utils.py#L364
• subjects: https://github.com/stanfordnmbl/opencap-core/blob/main/utils.py#L397

Could we optimize things on the frontend side such that not everything is being loaded? I believe you did something similar to optimize speed previously. While it is only a problem for admin at this stage, this might become a problem from actual users who have a lot of data.

Here is a video that describes what is happening:

Hi @olehkorkh-planeks,I am still having issues. It says no data available. The console reports some network errors. This all seems related to the subject tags we recently added. Subject tags are not "part" of subjects (see below), so I am guessing that even if we optimize loading for subjects, we might not be optimizing for subject tags? (just some thoughts). It works fine for non-admin users, probably because they have fewer subjects. Let me know if there is anything I can do to help you fix this (eg, give you access to admin account).

Hi @antoinefalisse Yes, I need to research it. Please, provide me your access credentials. I need an access to the account (including admin). I'm also thinking that maybe I'll need to download the dump of the database for local tests. If it is possible, I need to check it as well. Because, maybe, we'll need some more radical architecture changes for the frontend.

• [x] Filtering by session name, subject name, number of trials does not seem to work
• [x] When loading a session, you first see the data from the previous session you loaded before the data from the current session is loaded.
• [x] Intermittently loading app.opencap.ai/step1 instead of app.opencap.ai/sessions when logging in, see this video
• [x] Some problem with the subject selection, see this video and this video
• [x] the subject you create does not get automatically selected, see this video
• [x] getting this Could not reach server error, I am not sure why. I got it many times on step4 during my tests with the new changes. See in video above when I got it.

@olehkorkh-planeks two more small bugs:

• [ ] No data available shows up for a fraction of second when you click on dropdown
• [ ] Subjects get edited without needing to save, mandatory fields can be left empty

see this video for details.
