Firebase 创建文档并递增

Question

I am trying to increment a value for my documents; Sometimes the document does not exist, so I need to create it and then update it.

    my_ref = db.collection(u'my_col').document(f"my_doc_key")
    my_doc = my_ref.get()

    if my_doc.exists:
        my_ref.update({"count": firestore.Increment(1)})
    else:
        my_ref.set({"count": 1})

I know I can use update() and Increment() if the document exists. I know that if the document does not exist, I can create it and set a collection inside it with set() . Is there a way I can do this in one method? Something like this:

    my_ref.set({"count": firestore.Increment(1)})

Solved it using merge=True parameter

     my_ref = db.collection(u'my_col').document(f"my_doc_key")
     my_ref.set({"count": firestore.Increment(1)}, merge=True)
