Thanks for your responses. Now when I try
ret = { }
ret['a'] = 'b'
serialized = encoder.JSONEncoder().encode(ret)
print serialized
then It works.
But now I have another problem. I have a class "State":
class State(models.Model):
state = models.CharField(max_length = 30)
def __unicode__(self):
return self.state
Throutht the admin page I create a state called "Slaskie".
Then the code :
ret['b'] = State.objects.all()
print 'ret: %' % ret
try:
serialized = encoder.JSONEncoder().encode(ret)
except Exception, e:
print 'exception: %s' % e
returns the output:
{'b': [<State: Slaskie>]}
[<State: Slaskie>] is not JSON serializable
At the page
http://docs.djangoproject.com/en/dev/topics/serialization/#id2 there's
written something about unicode and lazy translation. I tried to use
le = LazyEncoder() #lazy encoder is a given class from the
link above
serialized = le.encode(ret)
and then the exception was:
Circular reference detected
when I tried
le = LazyEncoder (ensure_ascii = False)
the exception was the same:
Circular reference detected
What's going on with this lazy translation and unicode ? How can I
serialize the data correctly ?

Marek
