Python MongoDB Insert

🎯 한 줄 통찰 (One-line insight)

If you don't supply an _id, MongoDB auto-generates a unique one for every document — but if you DO supply _id values yourself (e.g. sequential integers), you're responsible for ensuring they're unique across the collection. [S1]

🧠 핵심 개념 (Core concepts)

• Document — MongoDB's equivalent of a SQL record; a dictionary of field names/values. [S1]
• insert_one(dict) — inserts a single document. [S1]
• InsertOneResult.inserted_id — the ID of the just-inserted document. [S1]
• Auto-generated _id — assigned automatically if not specified, guaranteed unique. [S1]
• insert_many(list_of_dicts) — inserts multiple documents at once. [S1]
• InsertManyResult.inserted_ids — list of IDs for all inserted documents. [S1]
• Custom _id values — can be specified manually, but must be unique — MongoDB won't auto-check for you beyond the uniqueness constraint. [S1]

📖 세부 내용 (Details)

• Insert one: mydict = {"name": "John", "address": "Highway 37"}; x = mycol.insert_one(mydict). [S1]
• Get inserted ID: print(x.inserted_id). [S1]
• Insert many: mylist = [{"name": "Amy", ...}, ...]; x = mycol.insert_many(mylist); print(x.inserted_ids). [S1]
• Insert many with custom IDs: mylist = [{"_id": 1, "name": "John", ...}, {"_id": 2, ...}, ...]. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음. _id를 직접 지정할 경우 고유성은 사용자 책임임이 명시됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 이 삽입 작업이 실제로 데이터베이스/컬렉션을 처음 생성시키는 트리거다. [S1]

💻 코드 패턴 (Code patterns)

Insert many and get generated IDs (Python):

mylist = [
    {"name": "Amy", "address": "Apple st 652"},
    {"name": "Hannah", "address": "Mountain 21"},
]
x = mycol.insert_many(mylist)
print(x.inserted_ids)
