Is there a way to serialize the get_picture(self) method within this model? I am currently working on a social networking project and I need to serialize this method in order to obtain a JSON URL for the user's profile picture to be utilized in an Android application.
class Profile(models.Model):
user = models.OneToOneField(User)
location = models.CharField(max_length=50, null=True, blank=True)
url = models.CharField(max_length=50, null=True, blank=True)
job_title = models.CharField(max_length=50, null=True, blank=True)
class Meta:
db_table = 'auth_profile'
def __str__(self):
return self.user.username
def get_url(self):
url = self.url
if "http://" not in self.url and "https://" not in self.url and len(self.url) > 0: # noqa: E501
url = "http://" + str(self.url)
return url
def get_picture(self):
no_picture = 'http://trybootcamp.vitorfs.com/static/img/user.png'
try:
filename = settings.MEDIA_ROOT + '/profile_pictures/' +\
self.user.username + '.jpg'
picture_url = settings.MEDIA_URL + 'profile_pictures/' +\
self.user.username + '.jpg'
if os.path.isfile(filename):
return picture_url
else:
gravatar_url = 'http://www.gravatar.com/avatar/{0}?{1}'.format(
hashlib.md5(self.user.email.lower()).hexdigest(),
urllib.urlencode({'d': no_picture, 's': '256'})
)
return gravatar_url
except Exception:
return no_picture
