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 =
    data = odm.CharField()
    user = odm.ForeignKey("User")

    def __unicode__(self):

    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 ='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
User: pluto
>>> u.updates.size()
>>> 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
