Package: pymodm
A generic ODM aroundPyMongo, the MongoDB Python driver. PyMODM works on Python
2.7 as well as Python 3.3 and up. To learn more, you can browse theofficial
documentationor take a look at someexamples.Why PyMODM?PyMODM is a “core” ODM, meaning that it provides simple, extensible
functionality that can be leveraged by other libraries to target platforms like
Django. At the same time, PyMODM is powerful enough to be used for developing
applications on its own. Because MongoDB engineers are involved in developing
and maintaining the project, PyMODM will also be quick to adopt new MongoDB
features.Support / FeedbackFor issues with, questions about, or feedback for PyMODM, please look into
oursupport channels. Please do not
email any of the PyMODM developers directly with issues or questions -
you’re more likely to get an answer on theMongoDB Community Forums.Bugs / Feature RequestsThink you’ve found a bug? Want to see a new feature in PyMODM? Please open
a case in our issue management tool, JIRA:Create an account and login.Navigate tothe PYMODM project.ClickCreate Issue- Please provide as much information as possible about the issue type and how to reproduce it.Bug reports in JIRA for all driver projects (e.g. PYMODM, PYTHON, JAVA) and the
Core Server (i.e. SERVER) project arepublic.How To Ask For HelpPlease include all of the following information when opening an issue:Detailed steps to reproduce the problem, including full traceback, if possible.The exact python version used, with patch level:$ python -c "import sys; print(sys.version)"The exact version of PyMODM used, with patch level:$ python -c "import pymodm; print(pymodm.version)"The PyMongo version used, with patch level:$ python -c "import pymongo; print(pymongo.version)"The operating system and version (e.g. Windows 7, OSX 10.8, …)Web framework or asynchronous network library used, if any, with version (e.g.
Django 1.7, mod_wsgi 4.3.0, gevent 1.0.1, Tornado 4.0.2, …)Security VulnerabilitiesIf you’ve identified a security vulnerability in a driver or any other
MongoDB project, please report it according to theinstructions here.ExampleHere’s a basic example of how to define some models and connect them to MongoDB:frompymongoimportTEXTfrompymongo.operationsimportIndexModelfrompymodmimportconnect,fields,MongoModel,EmbeddedMongoModel# Connect to MongoDB first. PyMODM supports all URI options supported by# PyMongo. Make sure also to specify a database in the connection string:connect('mongodb://localhost:27017/myApp')# Now let's define some Models.classUser(MongoModel):# Use 'email' as the '_id' field in MongoDB.email=fields.EmailField(primary_key=True)fname=fields.CharField()lname=fields.CharField()classBlogPost(MongoModel):# This field references the User model above.# It's stored as a bson.objectid.ObjectId in MongoDB.author=fields.ReferenceField(User)title=fields.CharField(max_length=100)content=fields.CharField()tags=fields.ListField(fields.CharField(max_length=20))# These Comment objects will be stored inside each Post document in the# database.comments=fields.EmbeddedDocumentListField('Comment')classMeta:# Text index on content can be used for text search.indexes=[IndexModel([('content',TEXT)])]# This is an "embedded" model and will be stored as a sub-document.classComment(EmbeddedMongoModel):author=fields.ReferenceField(User)body=fields.CharField()vote_score=fields.IntegerField(min_value=0)# Start the blog.# We need to save these objects before referencing them later.han_solo=User('mongoblogger@reallycoolmongostuff.com','Han','Solo').save()chewbacca=User('someoneelse@reallycoolmongostuff.com','Chewbacca','Thomas').save()post=BlogPost(# Since this is a ReferenceField, we had to save han_solo first.author=han_solo,title="Five Crazy Health Foods Jabba Eats.",content="...",tags=['alien health','slideshow','jabba','huts'],comments=[Comment(author=chewbacca,body='Rrrrrrrrrrrrrrrr!',vote_score=42)]).save()# Find objects using familiar MongoDB-style syntax.slideshows=BlogPost.objects.raw({'tags':'slideshow'})# Only retrieve the 'title' field.slideshow_titles=slideshows.only('title')# u'Five Crazy Health Foods Jabba Eats.'print(slideshow_titles.first().title)
