Some simple examples of what MongoEngine code looks like:

class BlogPost(Document):
    title = StringField(required=True, max_length=200)
    posted = DateTimeField(
    tags = ListField(StringField(max_length=50))

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']

# Create a link-based post
>>> post2 = LinkPost(title='MongoEngine Docs', url='')
>>> post2.tags = ['mongoengine', 'documentation']

# 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
...     print

>>> len(BlogPost.objects)
>>> len(HtmlPost.objects)
>>> len(LinkPost.objects)

# Find tagged posts
>>> len(BlogPost.objects(tags='mongoengine'))
>>> len(BlogPost.objects(tags='mongodb'))


To run the test suite, ensure you are running a local instance of MongoDB on the standard port, and run: python test.
