Sync local DB with production DB

Question

Sync local DB with production DB

kulla opened this issue a year ago · comments

There seems to be a difference between local and production DB, see https://serlo.slack.com/archives/C04TTH20JP5/p1686553440157629

Target of this issue: Investigate the change and update the local DB so be in sync with production DB

How to do it?

yarn mysql:rollback -> Make sure the local DB is the one of https://github.com/serlo/database-layer/blob/main/docker-entrypoint-initdb.d/001-init.sql
yarn mysql -> Make changes to the SQL tables
yarn mysql:dump -> Save changes of DB in https://github.com/serlo/database-layer/blob/main/docker-entrypoint-initdb.d/001-init.sql

heyy! I was to trying to solve this issue but when i tried installing sqlx-cli it failed with error
error: failed to compile sqlx-cli v0.6.3, intermediate artifacts can be found at /tmp/cargo-installOCgsQp
I have installed rust and docker and also have cargo on my local machine is there anything else I can do to solve this issue

Hi @tiwariParth
Thanks for your motivation to solve this issue!
Since we actually don't really know what changes have to be made in the sql tables, I would recommend you to start with another issue: could you try to tackle #343 ?

Regarding your compile issue we can't know, have taken a look at stackoverflow or at the sqlx-cli repo?

Maybe you can send us more information (like logs of the build, e.g. in /tmp/cargo-installOCgsQp)
