ORA-01861: literal does not match format string when executing get model object in django

I have a model object in django like so...
from django.db import models
class Person(models.Model):
employee_title = models.CharField(max_length=150)
pk_person_id = models.IntegerField(primary_key=True)
department_name = models.CharField(max_length=240)
cost_center = models.CharField(max_length=150)
user_name = models.CharField(max_length=100)
def __str__(self):
return self.user_name
class Meta:
managed = False
db_table = 'company_hr_idm_data_v'
and in my view I am doing a simple get on the Person object like so...
testobj = Person.objects.using('oracle').get(pk=4)
The code errors out with a DatabaseError that says
ORA-01861: literal does not match format string
Here is the stack trace I code when I have my debug mode set to true in my settings.py

Oh! also here is the query that is generated...
SELECT * FROM (SELECT ROWNUM AS "_RN", "_SUB".* FROM (SELECT "COMPANY_HR_IDM_DATA_V"."EMPLOYEE_TITLE", "COMPANY_HR_IDM_DATA_V"."PK_PERSON_ID", "COMPANY_HR_IDM_DATA_V"."DEPARTMENT_NAME", "COMPANY_HR_IDM_DATA_V"."COST_CENTER", "COMPANY_HR_IDM_DATA_V"."USER_NAME" FROM "COMPANY_HR_IDM_DATA_V" WHERE "COMPANY_HR_IDM_DATA_V"."PK_PERSON_ID" = :arg0) "_SUB" WHERE ROWNUM <= 21) WHERE "_RN" > 0
I tried to put as much information as I could, can anyone please steer me in the right direction?

Can you try executing the Query directly by giving the input?. There might be a datatype difference between the input and the actual column type.

relation "account_emailaddress" does not exist - django error

I am following this tutorial to integrate social media login to my django project -
http://www.sarahhagstrom.com/2013/09/the-missing-django-allauth-tutorial/
However after completing all the steps, when I try to login using facebook, I get this error
relation "account_emailaddress" does not exist
I don't understand what has gone wrong as all the DB modifications ran properly without errors.
Thanks in advance for your valuable answers.

I figured out what the problem was. the allauth uses account app which doesn't support migrations as yet. Initially I had run
python manage.py migrate allauth.socialaccount
python manage.py migrate allauth.socialaccount.providers.facebook
Along with this we need to run the syncdb to complete the puzzle.

I think you added library providers after performing the first migration, this leaves pending migrations
run
python manage.py makemigrations allauth
and
python manage.py migrate allauth

I checked the other questions on here like this one, but couldn't get an accurate answer that would solve my problem. When i run the dev server with python manage.py runserver I get the following `

`
But when i check my other project with which i follow the official django tut I dont have the mentioned views file in the project directory but I am able to see the admin page. Any suggestions why is the error being raised?

i think it will be more useful if just copy / paste error log . use:
./manage.py runserver --traceback
you need to add function in chinatown/views.py say "food"
and a url pattern in project's urls.py:
from django.conf.urls import url
urlpatterns = [
url(r'^food/$', 'chinatown.views.food'),
]

Note:I just need to install this application.I am intermediate in python.and beginner in Django.But professional in PHP,mysql and front end with jQuery

From what I see, the problem is likely to be related to the moca framework.
If your /opt/sana/mrs/admin.py file looks like this then the culprit is likely to be located at line 12 : the created field is refered in the exclude list, but not previously defined.
As I'm not sure about your needs here are some solutions you can try :
Re-install or update your moca frameword ;
Add a piece of code before the execute definition (not sure what's type it should be though) :
from django.db import models # You may also place it in the top of the file
created = models.DateField(blank=True, null=True)
Remove the created item from the exclude list (not sure about the impact though)
Hope it helps,

Django error 'too many values to unpack' in objects.get(id)

I have url like this http://gagandeepdesk/2690/ which I am filtering with urls.py file and sending 2690 as one of the parameters to the function.
my urls.py filter looks like this,
url(r'^(\d+)/', 'scango.scanner.views.download'),
And that function looks like this,
def download(request, MediaId):
media = Media.objects.get(id=int(MediaId))
#print media
return HttpResponse(FileIterWrapper(open(media.path)))
I am getting error 'too many values to unpack' on line
media = Media.objects.get(id=int(MediaId))
I also tried running this function standalone without request object and it is running perfectly fine. So, I am confused what I have done wrong here.

Maybe try this instead?
This is an example of named groups.
In Python regular expressions, the syntax for named regular expression
groups is (?Ppattern), where name is the name of the group and
pattern is some pattern to match.
