It's also worth mentioning that any SIGNALS on any created object WILL be called when you use loaddata. I say this as someone who just spent 4 hours banging their head against a wall.

Thanks. I was stuck for almost 2 days and solved my issue.

What about data that cannot read by json (Russian, or any other language), what should be done in such a case, I have tried something about writing new serializer, but there was nothing to be fixed

Great tutorial. It helped me a lot, thanks!

Hey, I tried what you suggested, but on using loaddata, I get a DeserializationError "ContentType matching query does not exist..", what could be the reason for that?

This is really good and very few channels on YouTube cover these topics.. I've used this commands and if we have like thousands of data, it will take more time to load or dump the data. What are your thoughts on using taking and dumping SQL backup in postgres, which does take and dump the backup very efficiently. And thanks for this and keep up the good work!

Thank you for this awesome tutorial, but I want to ask something. I'm using sqlite3 at local, PostgreSQL at server side. I want to change my local specific database tables to server database tables. The server database includes user information and related tables (ForeignKey, Many-To-Many). What I want is to dump some tables from the local to the server-side.
What do you think is my potential to get any errors? Thanks again

I got this error and I'm not sure what to do

Problem installing fixture 'D:\Python AppUser has no profile.

[davidmurphy]

Hmm.. I got "UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte"

Great explanation though.

Make dumpdata automatically after a certain time everyday in django.
