Preventing dot "." in keys breaks existing applications. - #162

We are trying very hard to protect current users from inserting data into MongoDB with dots and dollars in field names—such field names are poorly supported and extremely difficult to work with. Meanwhile, you can pass check_keys=False to insert, update, and save to support your current schema.

was not aware of this check_keys=False option.
thanks,
While $name makes perfectly sense, having a dot is way different becomes an issue only if one use dot notation rather than strings, i.e. doc._id rather than doc["_id"].

However, there are zillions of cases where the dot is an organic part of a data item, which makes it perfect candidate for a key, e.g.

"example.com/index.html":  { ... }
"v1.1" :  { ... }
"package.module.function"

and so on and so forth.

The check_keys=False is a very good solution for me. However, I would suggest not treating $key and ke.y the same way.

Thanks a million for the mongo, pymongo, and Motor by the way.
It is a great pleasure working with those tools.

We prevent dots because in most circumstances, it makes querying on those
fields hard. Glad check-keys works for you!
