About
=====
MongoEngine is a Python Object-Document Mapper for working with MongoDB.
Documentation is available at https://mongoengine-odm.readthedocs.io - there
is currently a `tutorial <https://mongoengine-odm.readthedocs.io/tutorial.html>`_,
a `user guide <https://mongoengine-odm.readthedocs.io/guide/index.html>`_, and
an `API reference <https://mongoengine-odm.readthedocs.io/apireference.html>`_.
Supported MongoDB Versions
==========================
MongoEngine is currently tested against MongoDB v3.6, v4.0, v4.4, v5.0, v6.0 and v7.0. Future versions
should be supported as well, but aren't actively tested at the moment. Make
sure to open an issue or submit a pull request if you experience any problems
with a more recent MongoDB versions.
Installation
============
We recommend the use of `virtualenv <https://virtualenv.pypa.io/>`_ and of
`pip <https://pip.pypa.io/>`_. You can then use ``python -m pip install -U mongoengine``.
You may also have `setuptools <http://peak.telecommunity.com/DevCenter/setuptools>`_
and thus you can use ``easy_install -U mongoengine``. Another option is
`pipenv <https://docs.pipenv.org/>`_. You can then use ``pipenv install mongoengine``
to both create the virtual environment and install the package. Otherwise, you can
download the source from `GitHub <http://github.com/MongoEngine/mongoengine>`_ and
run ``python setup.py install``.
The support for Python2 was dropped with MongoEngine 0.20.0
Dependencies
============
All of the dependencies can easily be installed via `python -m pip <https://pip.pypa.io/>`_.
At the very least, you'll need these two packages to use MongoEngine:
- pymongo>=3.4
If you utilize a ``DateTimeField``, you might also use a more flexible date parser:
- dateutil>=2.1.0
If you need to use an ``ImageField`` or ``ImageGridFsProxy``:
- Pillow>=2.0.0
If you need to use signals:
- blinker>=1.3
Examples
========
Some simple examples of what MongoEngine code looks like:
.. code :: python
from mongoengine import *
connect('mydb')
class BlogPost(Document):
title = StringField(required=True, max_length=200)
posted = DateTimeField(default=datetime.datetime.utcnow)
tags = ListField(StringField(max_length=50))
meta = {'allow_inheritance': True}
class TextPost(BlogPost):
content = StringField(required=True)
class LinkPost(BlogPost):
url = StringField(required=True)
# Create a text-based post
>>> post1 = TextPost(title='Using MongoEngine', content='See the tutorial')
>>> post1.tags = ['mongodb', 'mongoengine']
>>> post1.save()
# Create a link-based post
>>> post2 = LinkPost(title='MongoEngine Docs', url='hmarr.com/mongoengine')
>>> post2.tags = ['mongoengine', 'documentation']
>>> post2.save()
# Iterate over all posts using the BlogPost superclass
>>> for post in BlogPost.objects:
... print('===', post.title, '===')
... if isinstance(post, TextPost):
... print(post.content)
... elif isinstance(post, LinkPost):
... print('Link:', post.url)
...
# Count all blog posts and its subtypes
>>> BlogPost.objects.count()
2
>>> TextPost.objects.count()
1
>>> LinkPost.objects.count()
1
# Count tagged posts
>>> BlogPost.objects(tags='mongoengine').count()
2
>>> BlogPost.objects(tags='mongodb').count()
1
Tests
=====
To run the test suite, ensure you are running a local instance of MongoDB on
the standard port and have ``pytest`` installed. Then, run ``python setup.py test``
or simply ``pytest``.
To run the test suite on every supported Python and PyMongo version, you can
use ``tox``. You'll need to make sure you have each supported Python version
installed in your environment and then:
.. code-block:: shell
# Install tox
$ python -m pip install tox
# Run the test suites
$ tox
If you wish to run a subset of tests, use the pytest convention:
.. code-block:: shell
# Run all the tests in a particular test file
$ pytest tests/fields/test_fields.py
# Run only particular test class in that file
$ pytest tests/fields/test_fields.py::TestField
