You should probably use alkali if you want to use JSON as DB.
Zerorm is trying to combine TinyDB, Schematics and Lifter together to look like an ORM.
pip install zerormFirst declare a model with TinyDB's instance attached to it:
from zerorm import db, models
database = db('db.json')
class Message(models.Model):
author = models.StringType(required=True)
author_email = models.EmailType()
text = models.StringType()
replies = models.IntType(min_value=0)
class Meta:
database = databaseNow create some objects:
>>> from models import Message
>>>
>>> bob_message = Message(author='Bob',
... author_email='[email protected]',
... text='Hello, everyone!')
>>> bob_message
<Message: Message object>
>>> bob_message.save() # Save object
1
>>>
>>> bob_message.replies = 1
>>> bob_message.save() # Update object
>>>
>>> alice_message = Message.objects.create(author='Alice',
... text='Hi, Bob!',
... replies=0)
>>> alice_message
<Message: Message object>And try to retrieve them via objects
>>> Message.objects.all()
<QuerySet, len() = 2>
>>> list(Message.objects.all())
[<Message: Message object>, <Message: Message object>]
>>>
>>> second_message = Message.objects.get(id=2)
>>> second_message.author
'Alice'
>>>
>>> Message.objects.filter(replies__gte=1) # Only Bob's message has 1 replies
<QuerySet, len() = 1>
>>> list(Message.objects.filter(replies__gte=1))
[<Message: Message object>]You can redefine model's __str__ method for better repr.
class Message(models.Model):
...
def __str__(self):
return 'by {}'.format(self.author)>>> list(Message.objects.all())
[<Message: by Bob>, <Message: by Alice>]MIT. See LICENSE for details.
