[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. `_id`를 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): ```python mylist = [ {"name": "Amy", "address": "Apple st 652"}, {"name": "Hannah", "address": "Mountain 21"}, ] x = mycol.insert_many(mylist) print(x.inserted_ids) ``` ## ✅ 검증 상태 및 신뢰도 - **상태:** draft - **검증 단계:** conceptual - **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body) - **신뢰 점수:** 0.90 - **중복 검사 결과:** 신규 생성 (New discovery) ## 🔗 지식 그래프 (Knowledge Graph) - **상위/루트:** [[Python Tutorial]] - **관련 개념:** [[Python MongoDB Create Collection]], [[Python MongoDB Find]], [[Python MySQL Insert]] - **참조 맥락:** 데이터베이스/컬렉션을 실제로 생성시키는 트리거 — Find 챕터에서 이 데이터를 조회한다. ## 📚 출처 (Sources) - [S1] W3Schools — Python MongoDB Insert Document — https://www.w3schools.com/python/python_mongodb_insert.asp ## 📝 변경 이력 (Change history) - 2026-07-04: Initial draft synthesized from the W3Schools "Python MongoDB Insert Document" page (Astra wiki-curation, P-Reinforce v3.1 format).
