mongospecs

Built on top of the https://github.com/GetmeUK/MongoFrames ODM, with:

• Pydantic (BaseModel), attrs (@define), and msgspec (Struct) support for defining schema models (specs)
• Type-hints
• Spec adapters
  • Build a spec out of existing BaseModels, attrs classes, or Structs
• Raw BSON encode/decode for specs/mongo documents

Install

Choose from one of the following:

• pip install mongospecs for msgspec only
• pip install mongospecs[pydantic] for msgspec and pydantic only
• pip install mongospecs[attrs] for msgspec and attrs only
• pip install mongospecs[pydantic,attrs] for msgspec, pydantic, and attrs

Example

# Import Spec, either...
## 1. with pydantic:
from mongospecs.pydantic import Spec

## 2. with msgspec:
from mongospecs.msgspec import Spec

## 3. with attrs:
from mongospecs.attrs import Spec

# Define schema model
class Dragon(Spec):
    _collection = "dragons" # Optional. If not defined, uses the class name by default.

    name: str
    breed: Optional[str] = None

# create
burt = Dragon(name="Burt", breed="Cold-drake")
print(burt.name)  # Burt
print(burt.breed) # Cold-drake

# insert
burt.insert()
print(burt.id)  # inserted document ObjectId

# fetch
doc = Dragon.find_one({"name": "Burt"})  # returns raw mongo document

# delete
burt.delete()
