Python Persistence/ORM Module

[Christopher Coté]

I'm writing to let people know I've released a shiny new persistence
framework for Python and MongoDB.

It's called Humongolus. https://github.com/entone/Humongolus

Please feel free to try it out, I think you'll really like the
implementation. It's easy to use and stays out of the way when you
need it to.

I've used it on several large projects.

There's a pretty basic usage example in the readme, that should get
you started.

Also, 100% test coverage!

[Bernie Hackett]

Cool! I'll add it to the tools section of the PyMongo docs.

Hey! I'm just starting with Python/Django like NOW, coming from
Ruby on Rails/mongoid.

Sorry if it's a dumb question. Is it possible to use your 'driver'
with Django? How?

Thanks,

davi

It is similar to the django model system, and i know there's some people working on a nosql version of django, but i have not tested it. If i have some time i would love to try to get it working.

Short answer. No.

I currently use it with a custom tornado/mako system

You might want to check out django-mongodb-engine:

http://django-mongodb.org/

Please note it requires django-nonrel, not mainline django.

MongoEngine also includes some tools for working with django:

Very cool work!

Nice!

2 questions:

1. When would you have s simple widgets example/Tutorial up?
2. How is the speed compared to barebones Pymongo? Much overhead?


Thanks

I'll be putting together some tutorials over the next week, hopefully
get a few up tonight on wiki.

I'll also get some benchmarks together.

[Christopher Coté]

Some benchmarks.

The models:

class Job(orm.EmbeddedDocument):
title = field.Char()

class Human(orm.Document):
_db = "test"
_collection = "humans"
name = field.Char(required=True, min=2, max=25)
age = field.Integer(min=0, max=3000)
height = field.Float(min=1, max=100000)
weight = field.Float(min=1, max=30000)
jobs = orm.Relationship(type=Job)
genitalia = field.Char()

The dict:

human = {
"name":"Chris",
"age": 31,
"height":120,
"weight":180,
"jobs":[],
"genitalia":"outy"
}

100 inserts, safe=True

pymongo:
0.116407871246

humongolus:
0.271687984467

retrieving the data while printing the name

pymongo:
0.00512504577637

humongolus:
0.068286895752

I added benchmark.py to the repo as well.

I'm right now testing DRM?? (ORM) libs for python/mongo. Something i have not found is how to map or handle documents with diferent keys at orm level.

I'm testing you's right now

[Christopher Coté]

different keys?

as in the field in the db is diffrerent then the field name in the
model?

this is actually pretty easy to implement, it's in another ORM i
built. i can think about adding it in.

It is definitely nice for getting around python reserved words.

Congratulations Chris, I'm looking forward to playing with it.

hi，all

 I set up a mongodb cluster with every mongod process started with "--keyFile" option.

mongos:                                         port 27017

mongod:    shard1  primary        port 27200

mongod:    shard1  secondary   port 27201

mongod:    shard2  primary        port 27202

mongod:    shard2  secondary   port 27203

config:                                             port 27019

then, I found I can't connect to mongod and get the serverStatus via java-driver.

my code is like this:

Mongo mongo = new Mongo("localhost", 27200);

DB testDB = mongo.getDB("test");

CommandResult resp = testDB.command("serverStatus");

System.out.println(resp);

the result is :

{ "serverUsed" : "localhost:27200" , "errmsg" : "need to login" , "ok" : 0.0}

but if I run 'mongo' in my console to connect to localhost:27200, I can get the serverStatus result.

[Christopher Coté]

Please do, I would love any feedback.

[Eliot Horowitz]

See http://groups.google.com/group/mongodb-user/browse_thread/thread/8d5d2261964b96d8

[Christopher Coté]

A few updates,

Relationship is now called List.

I've added support for dbkey, meaning the key in mongo can differ from
that of your model attribute.

Basic html widgets.

All fields have dynamic validation now, meaning you can pass in your
own validation methods.

As far as tutorials, if you look through the tests directory as well
as test.py there are a lot of usage examples.

I'll be writing these up in more detail soon,

[Voltron]

Great! Would there be a form widghet class soon? It would be great and
make it a complete alternative to WTForms

[Christopher Coté]

Sounds like a good next step. I'll see what I can get into this
weekend ;)

[Voltron]

May I suggest this fork of WTForms as study material?

https://github.com/lepture/tforms

[Voltron]

Hi there! More questions :)

1. Is there going to be BSON, GridFS support soon?
2. Would you get your own google group?

Thanks

[Christopher Coté]

Voltron, I've created a google group here http://groups.google.com/group/humongolus

Also, I'll see about adding in BSON, GridFS and Binary fields soon.

I got started on the Form widget, pretty basic right now, think it
needs a little re-factoring.

[Christopher Coté]

A quick update, I've updated the Form widget system , it's pretty
robust now.

Also added a File field, basically a thin wrapper around the GridFS
class.

Documentation is also coming along.

Sphinx seems to have some issues with virtualenv, I'll be looking into
it a bit more.

Hey guys, just an update.

I've tagged version 1.0.0 on Github and it's also on the PyMongo tools page.

Hope you get some time to play with it, I think it's a great framework ;)

[Christopher Coté]

oh and the github page is here. http://entone.github.com/Humongolus/
