Hi,
I saw your comment on this article. https://www.netlandish.com/blog/2020/06/22/full-text-search-django-postgresql/
I am trying to implement the same thing in my django app and I had to change my save function to this
https://github.com/jsagoe1/Python_Stuff/blob/master/models_temp.py

I read in another article that the model instance has to be created before the search vector member can be updated.
Please let me know what you think.
