    <p>I want to use pymongo connection and methods to work with mongodb, but at the same time i want using mongoengine ORM.</p> <p>Sample:</p> <pre><code>class User(Document): email = StringField(required=True) first_name = StringField(max_length=50) last_name = StringField(max_length=50) john = User(email='jonhd@example.com') john.first_name = 'Jonh' john.last_name = 'Hope' </code></pre> <p>And now i want to insert new formed document User into my 'test_collection'. In case using only mongoengine i can do this:</p> <pre><code>connect('test_database') john.save() </code></pre> <p>And then i can make easy accessing my data:</p> <pre><code>for user in User.objects: print user.first_name </code></pre> <p>But when i'm trying to do same using pymongo, i've got an error:</p> <pre><code>connection = MongoClient('localhost', 27017) db = connection.test_database collection = db.test_collection collection.insert(john) </code></pre> <p>Traceback:</p> <pre><code>Traceback (most recent call last): File "C:/Users/haribo/PycharmProjects/test/mongoeng.py", line 18, in &lt;module&gt; collection.insert(john) File "C:\Python27\lib\site-packages\pymongo\collection.py", line 353, in insert docs = [self.__database._fix_incoming(doc, self) for doc in docs] File "C:\Python27\lib\site-packages\pymongo\database.py", line 258, in _fix_incoming son = manipulator.transform_incoming(son, collection) File "C:\Python27\lib\site-packages\pymongo\son_manipulator.py", line 73, in transform_incoming son["_id"] = ObjectId() TypeError: 'str' object does not support item assignment </code></pre> <p>But this works:</p> <pre><code>connection = MongoClient('localhost', 27017) db = connection.test_database collection = db.test_collection john = { 'email': 'jonhd@example.com', 'first_name': 'Jonh', 'last_name': 'Hope' } collections.insert(john) </code></pre> <p>And accessing data using pymongo:</p> <pre><code>print collection.find_one() {u'last_name': u'Hope', u'first_name': u'Jonh', u'_id': ObjectId('513d93a3ee1dc61390373640'), u'email': u'jonhd@example.com'} </code></pre> <p>So, my main idea and question is:</p> <p>How i can using mongoengine for ORM and pymongo connection and methods to working with mongodb?</p> <p>P.S. I mentioned that i want use it in pyramid for some context.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
