Field GeneratorΒΆ
This tutorial is about the use of JSONField with parameter JSONField.as_string set to False. Lets start with a model for a general data feed:
class Feed(odm.StdModel):
name = odm.SymbolField()
data = odm.JSONField(as_string=False)
lets create an instance:
feed = Feed(name='goog').save()
feed.data = {'price': {'bid': 750, 'offer':751},
'volume': 2762355371,
'mkt_cap': '255B',
'pe': 23}
feed.save()
When loading the instance one can access all the fields in the following way:
feed.data['price']['bid']
feed.data['price']['offer']
or equivalently:
feed.data__price__bid
feed.data__price__offer
