[vote] Models changes for new vote service - #575

Yes, quite a lot.

Os-go: OpenSlides/openslides-go#312
Vote-Service: OpenSlides/openslides-vote-service#590
Autoupdate: OpenSlides/openslides-autoupdate-service#1461

@vkrasnovyd Do we need an update for the backend as well?

Minor: re-generating the models and adjusting some tests. Will do today.

Please wait one moment. We want to change the model again. We want to have both, meeting_user_id an user_id. If you do not have a meeting_user in the migration, its ok to only write user_id.

Please also check, that if a meeting_user gets deleted, it does not delete the poll_option, but only the field meeting_user_id.

We want to do the same for poll_ballot_user. The meeting_user fields will be optional and the user-field is required. If the backen removes a meeting_user, it should not delete the poll_ballot_user, but only clear the field meeting_user (for acting_user and represented_user).

Please also check, that if a meeting_user gets deleted, it does not delete the poll_option, but only the field meeting_user_id.

It should be defined in meta, in meeting_user.yml. These 3 fields need to have on_delete: SET_NULL:

• poll_option_ids
• acting_ballot_ids
• represented_ballot_ids

I added all models changes, that we have discussed yesterday in here, so we can fix them in the services without merge conflicts.

@ostcar as far as I understood, according to the new concept poll/entitled_users_at_stop should be migrated (or kept). Is it so? Will the field name change to just entitled_users?

The current value of entitled_users_at_stop is json:

I don't know the format of it. In the new system, it is a list of numbers (a relation-list field)

os-go, autoupdate and vote service are ready.

@bastianjoel and @vkrasnovyd pls tell, when the other services are ready, and we can merge this into the feature/vote branch

backend will be ready in the first half of next week.

@bastianjoel and @vkrasnovyd Here are the changes as discussed

autoupdate: OpenSlides/openslides-autoupdate-service#1461
vote: OpenSlides/openslides-vote-service#590

Added on_delete to 2 fields:

• poll/entitled_user_ids: CASCADE - needed for backend
