Peewee - sqlite - new data is not added, but overwrites the previous ones. What am I missing?

Question

Python

when adding records, I use standard methods:
MyModel.create(**source_data)
or
MyModel.insert(source_data).execute()
Data is not added, but overwrites the previous ones.
Almost all settings are default.

Answer 1

Didn't work with Peewee specifically, but is .commit() done after data is entered? It seems like here, by analogy, for example with SQLAlchemy, when entering new data, you need to commit: docs.peewee-orm.com/en/latest/peewee/api.html#Data...

Answer 2

Most likely, your records have the same primary key - that's why it is overwritten.
Show the model and what's in source_data.
