Django DoesNotExist - Matching Query doesn't exist
I'm working on a Django(1.4) and Python (2.7) project in which I have a custom model for user to get loggedin.
Here's my model:
from models.py:
class User_table(models.Model):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
address = models.CharField(max_length=300)
phone = models.CharField(max_length=20, null=True)
emailid = models.EmailField()
user_name = models.CharField(max_length=100)
password = models.TextField()
user_type = models.CharField(max_length=20)
# True means drive is available for delivery
status = models.BooleanField(default=True)
vehicle_no = models.CharField(max_length=50, blank=True, null=True)
gender = models.CharField(max_length=10)
profile = models.ForeignKey(AddedFile, on_delete=models.CASCADE, null=True, related_name='profile')
uploaded_document = models.ForeignKey(AddedFile, on_delete=models.CASCADE, null=True, related_name='document')
approval_status = models.BooleanField(default=False)
login_try = models.IntegerField(default=0)
is_active = models.BooleanField(default=False)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
def __str__(self):
return str(self.id)
And here's my view:
From views.py:
def mainlogin(request):
if request.method == "POST":
username = request.POST['username']
email = request.POST['email']
password = request.POST['password']
try:
obj = User_table.objects.get(user_name=username, emailid=email)
verify_password = ''
try:
verify_password = handler.verify(password, obj.password)
except Exception as e:
print(e)
if verify_password is True:
request.session['user_id'] = obj.id
request.session['user_type'] = obj.user_type
user_name = obj.first_name + ' ' + obj.last_name
request.session['user_name'] = user_name
if not obj.approval_status:

id) + ' key is : ' + str(key)
send_mail('Reset link', reset_link, settings.EMAIL_HOST_USER, [obj.emailid, ])
obj.password = str(key)
obj.save()
return HttpResponse(
'It seems you forgot password or someone is trying to login you account. Password Reset link has been sent to your email id')
except Exception as e:
print(e)

return redirect(mainlogin)

print('error is : ', e)
return HttpResponse('An error has occurred.')
if request.method == "GET":
try:
return render(request, "login.html")
except Exception as e:
print(e)
When I try to log in it returns an error:
(u'error is : ', DoesNotExist('User_table matching query does not exist.',))
I ahve taken a look into the database and confirm that I have the record which I'm trying to get from the view, but it still through this error.
What can be wrong here?
Help me, please!
Thanks in advance!

I think there is an issue with your indentation. It's hard to understand your code. I think theexcept
that seems to be at the same level than theif
actually pairs with thetry
that seems not to haveexception
. Is that so?
