You can put this in models.py
file of the relevant app (such as main/
). What post_save.connect(create_api_key, sender=User)
does is that everytime an User
instance is saved, create_api_key()
will be called.
Now let’s look into what create_api_key()
does by diving a bit into the source of tastypie:
class ApiKey(models.Model):
user = models.OneToOneField(User, related_name='api_key')
key = models.CharField(max_length=256, blank=True, default='')
created = models.DateTimeField(default=datetime.datetime.now)
def __unicode__(self):
return u"%s for %s" % (self.key, self.user)
def save(self, *args, **kwargs):
if not self.key:
self.key = self.generate_key()
return super(ApiKey, self).save(*args, **kwargs)
def generate_key(self):
# Get a random UUID.
new_uuid = uuid.uuid4()
# Hmac that beast.
return hmac.new(str(new_uuid), digestmod=sha1).hexdigest()
def create_api_key(sender, **kwargs):
"""
A signal for hooking up automatic ``ApiKey`` creation.
"""
if kwargs.get('created') is True:
ApiKey.objects.create(user=kwargs.get('instance'))
As you can see, create_api_key()
will create a new ApiKey
record, which will be related to the calling User
. This record will also have a HMAC key when it was saved to the ApiKey
table. The key is generated by generate_key()
function.
