Installing

DStore-Mongo is available from the PyPi repository.

This means that all you have to do to install DStore-Mongo is run the following in a console:

$ pip install dstore-mongo

Minimal Example

from dstore import Model, var, mod
from dstore_mongo import MongoStore

class Car( Model ):
    _namespace = "cars.make"
    _vars = [
        var.RowID,
        var.String( "manufacturer", 32, mods = [ mod.NotNull() ] ),
        var.String( "make", 32, mods = [ mod.NotNull() ] ),
        var.Number( "year", mods = [ mod.NotNull(), mod.Min( 1950 ), mod.Max( 2017 ) ] ),
    ]

# Create the MemoryStore instance, and add Models to it
store = MongoStore( self.models )
store.init_app()
store.set_config({
    "DSTORE_DB_HOST"  : "localhost",
    "DSTORE_DB_USER"  : "username",
    "DSTORE_DB_PASSWD": "password",
    "DSTORE_DB_DB"    : "dstoredb"
})
store.connect()
store.create_all()

# Destroy all instances and shut down the application
store.destroy_all()
