# [[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. `_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)
```
