Re: Error at OneToOneField in models while creating new models class

Thank you for the response,
1. Deleted the migrations folder
2. Removed the SQLite3 DB itself
3. My dir structure.
24-09-2018  16:37    <DIR>          .
24-09-2018  16:37    <DIR>          ..
23-09-2018  15:06    <DIR>          college
19-09-2018  08:56               554 manage.py
19-09-2018  10:59    <DIR>          section
               1 File(s)            554 bytes
               4 Dir(s)  32,464,281,600 bytes free

4. Execute the makemigrations, but it prompting with the error. 
C:\Users\srini\djangoProjects\college>python manage.py makemigrations section
App 'section' could not be found. Is it in INSTALLED_APPS?

5. FYI: Also registered in apps.py
from django.apps import AppConfig


class ClassConfig(AppConfig):
name = 'section'

First you have to change your model name Class names starts with uppercase...

My friend.. you are not making migrations... look at you have to do this:


1. Delete your migration folder
2. Delete you app table manually (DROP table)
3. python manage.py makemigrations app_name
4. migrate

that's all

HI All,

I am facing below error while creating a new model class.
the error pop up only at this line "user = models.OneToOneField(User)"
"E1120:No value for argument 'on_delete' in constructor call"

from django.db import models
from django.contrib.auth.models import User

class userProfile(models.Model):
user = models.OneToOneField(User)

If I add "user = models.OneToOneField(User,on_delete=models.CASCADE)" the error got subsided but the new class "userProfile" is not appearing in admin page, under Users tab.

Could some one please guide me how to fix this ?
