A twitter cloneΒΆ
This is the stdnet equivalent of the redis twitter clone example. It illustrates the use of stdnet.odm.ManyToManyField and implicit sorting:
from datetime import datetime
from stdnet import odm
class Post(odm.StdModel):
timestamp = odm.DateTimeField(default = datetime.now)
data = odm.CharField()
user = odm.ForeignKey("User")
def __unicode__(self):
return self.data
class Meta:
ordering = '-timestamp'
class User(odm.StdModel):
'''A model for holding information about users'''
username = odm.SymbolField(unique = True)
password = odm.CharField(required = True)
following = odm.ManyToManyField(model = 'self',
related_name = 'followers')
def __unicode__(self):
return self.username
def newupdate(self, data):
return Post(data = data, user = self).save()
These models are available in the stdnet.tests module. We can import them by using:
from stdnet.tests.examples.models import Post, User
Before using the models, we need to register them to a back-end. If your redis server is running locally type:
>>> from stdnet import odm
>>> models = odm.Router('redis://')
>>> models.register(User)
>>> models.register(Post)
Now lets try it out:
>>> u = models.user.new(username='pluto', password='bla')
>>> u
User: pluto
Ok we have a user. Lets add few updates:
>>> u.newupdate('my name is Luka and I live on second floor')
Post: my name is Luka and I live on second floor
>>> u.newupdate('ciao')
Post: ciao
>>> u.save()
User: pluto
>>> u.updates.size()
2
>>> for p in u.updates:
... print('%s : %s' % (p.dt,p))
...
2010-11-10 18:05:59 : ciao
2010-11-10 18:05:24 : my name is Luka and I live on second floor
