Project description

sanic-mongo

====================

sanic的mongodb异步工具,灵感来源自 `官方例子 `_ 的封装,

目的只是为了简化操作.

更新

-----------------------

* v1.7.1 修正了mongo连接权限可能引发的问题,现在可以配置每个连接是否是只能连database,默认为False.{"uri":xxxx,"only_db":True}

* v1.6.0 修正了验证无法通过的问题

* v1.5.0 将接口调整至和sanic-aioorm一致.

特点 Features

-------------------------

* `motor `_ 支持的操作都支持

* 支持3.5版本以上的

* 支持多数据库

* 支持mongodb和gridfs

依赖 Requirements

-----------------------------

1. motor>=1.1

2. pymongo>=3.4.0

3. sanic>=0.4.1

安装 Installation

--------------------------

- ``pip install sanic-mongo``

用法

----------------------------

mongo需要给`app.config`设置关键字`MONGO_URIS`,它是一个由mongodb名字和url组成的字典.

同时也可以使用`Mongo.SetConfig(app,**kws)`来注册kws的内容到`MONGO_URIS`.

而使用的时候可以访问`app.mongo[mongodb名字]`访问对应的db

gridfs与之类似,只是关键字是`GRIDFS_SETTINGS`,而访问需要使用`app.GridFS[GridFS名字]`

例子 Example

-----------------------------------

1. mongodb

.. code:: python

from sanic import Sanic

from sanic.response import json

from sanic_mongo import Mongo

app = Sanic(__name__)

mongo_uri = "mongodb://{host}:{port}/{database}".format(

database='test',

port=27017,

host='localhost'

)

Mongo.SetConfig(app,test=mongo_uri)

Mongo(app)

@app.get('/objects')

async def get(request):

docs = await app.mongo['test'].test_col.find().to_list(length=100)

for doc in docs:

doc['id'] = str(doc['_id'])

del doc['_id']

return json(docs)

@app.post('/objects')

async def new(request):

doc = request.json

print(type(app.mongo['test']))

object_id = await app.mongo['test']["test_col"].save(doc)

return json({'object_id': str(object_id)})

if __name__ == "__main__":

app.run(host='127.0.0.1', port=8000,debug=True)

2. gridfs

.. code:: python

from sanic import Sanic

from sanic.response import json,text

from sanic_mongo import GridFS

app = Sanic(__name__)

mongo_uri = "mongodb://{host}:{port}/{database}".format(

database='test',

port=27017,

host='localhost'

)

GridFS.SetConfig(app,test_fs=(mongo_uri,"fs"))

GridFS(app)

@app.get('/pics')

async def get(request):

cursor = app.GridFS["test_fs"].find()

result = [{i._id:i.name} async for i in cursor]

return json({"result":result})

@app.post('/pics')

async def new(request):

doc = request.files.get('file')

async with app.GridFS["test_fs"].open_upload_stream(filename=doc.name,

metadata={"contentType": doc.type}) as gridin:

object_id = gridin._id

await gridin.write(doc.body)

return json({'object_id': str(object_id)})

if __name__ == "__main__":

app.run(host='127.0.0.1', port=8000,debug=True)
