database syncing best practices

In my internship, we are working with django and after each new big commit, we go by the practice of getting the database dump from the person that made the commit as the models might have changed and what not. I just think this way is way too crude and idk just naive i guess. I was wondering if there are better practices for database syncing between users. obviously, this is assuming we are not using any databases on the cloud. My best guess was to put up the sql dump in the git repo itself but then i myself know why thats bad for so many reasons(security,size….) so yeah, just a curious intern here.
