Adding documents with primary key not working

When adding documents and including a primary key, the primary key is getting set to None instead of the specified key. For example:

index.add_documents(small_movies, primary_key="title")
print(index.get_primary_key())

results in None being printed. Maybe I’m just not correctly understanding how to use the primary_key? The correct url of indexes/some-uid/documents?primaryKey=title is being generated. so the add_documents method seem to be doing what it is supposed to do.

I think it may be because of restricted characters on primary keys https://docs.meilisearch.com/learn/core_concepts/documents.html#primary-field

This actually brings up another point that confused me with update_documents. It takes primary_key as a parameter, but the primary key can’t be updated. So does that mean update_documents should not accept a primary key?

~Yes this should be removed!~

Actually if you look at the get_primary_key() method the only thing it does is call fetch_info()

Ah, you’re right, my bad. I will take a closer look tomorrow 😃
