Thunder is an ORM for MongoDB built on top of the PyMongo driver.
Thunder provides a Store class which provide apis for indexing and querying documents stored in MongoDB.
>>> from storm.store import Store
To create a simple store you can just provide the name of the database inside the mongo database:
>>> store = Store('mydb')
That's it, we now have a reference to store which can be used to insert and query objects.
First we need to define a document that can be inserted into a store:
>>> from storm.fields import ObjectIdField, StringField
>>> class Person(object): ... id = ObjectIdField() ... name = StringField()
All objects inserted into a store needs to at least have an ObjectIdField. There can only be one ObjectIdField per class.
To create a document you create the class normally:
>>> p = Person() >>> p.name = 'John Cleese' >>> store.add(p)
Note that this doesn't actually index the document into the database, that's only done when an explicit flush is issued:
>>> store.find(Person).count() 0
We can now query the store for the document:
>>> store.find(Person).count() 1
>>> for person in store.find(Person): >>> print person <X object at 0x.....>
