Solution for “TypeError: ‘Collection’ object is not callable” when using the insert command in Pymongo

I am working on a project that explicitly requires the insert command for creating a CRUD class using Python. I am using Pymongo-4 and did not know that the project implicitly required an older version of Pymongo, namely version 3.

This is how the insert method was used: 

self.database.animals.insert(data)

The result of using insert on a newer version of Pymongo issued the following error message: 

TypeError: 'Collection' object is not callable. If you meant to call the 'insert' method on a 'Collection' object it is failing because no such method exists.

The error message was a straightforward explanation. It says that the collection does not have a method called insert.

I was not sure what I needed to do at first, but the Pymongo changelog confirmed that insert is deprecated as of version 3.

The following methods are deprecated:

  • save()
  • insert()
  • update()
  • remove()
  • find_and_modify()
  • ensure_index()

My options were to use insert_one, insert_many, or downgrade my version of Pymongo below version 3. I went with the latter since I was required to use the insert command.

Conclusion

The solution for “TypeError: ‘Collection’ object is not callable” is to use a version of Pymongo that supports the insert method. Alternatively, you can use insert_one or insert_many if you wish to use a newer version of Pymongo.
