I am just starting out to develop a Django Blog, and am following this youtube tutorial - https://www.youtube.com/watch?v=7rgph8en0Jc&spfreload=1
I am using Django 1.6.6.
Everytime I try to add Entry in Admin, I get this error. Thanks for your help!

I guess, Entry.tags was added after table creation.
If it's possible to upgrade django to 1.7 then you can use built-in migrations.
Firstable reset your app to actual db schema, i.e. remove tags field, then:
# Create initial migrations
$ python manage.py makemigrations your_app
# Migrate
$ python manage.py migrate your_app
# Add your tags field. Repeat
$ python manage.py makemigrations your_app
$ python manage.py migrate your_app
If you want to stay on django 1.6, use South. It's pretty much the same:
# Create initial migrations
$ python manage.py schemamigration your_app intial --init
# Migrate
$ python manage.py migrate your_app --fake
# Add your tags field. Create migration
$ python manage.py schemamigration your_app add_tags --auto
$ python manage.py migrate your_app

I've set User as a foreign key on my Video model. I am using the default django auth User model, and have managed to create a user using the serializer and view that I set up for it. The problem is that whenever I try to create a video entry I hit the title error.
I've tried clearing the database, redoing the migrations, but there aren't any migrations for the app that handles the user serializer.
The Model
from django.contrib.auth.models import User
class Video(models.Model):
user = models.ForeignKey(
User,
on_delete=models.CASCADE,
null=True
)
map_marker = models.ForeignKey(MapMarker, on_delete=models.CASCADE)
created = models.DateTimeField()
ip_addr = models.TextField()
file_id = models.TextField()
class Meta:
ordering = ('created',)

The entry should be saved with the key of the user I selected on the API view.
Something got broken along the way and dropping the DB and starting again fixed the problem.
Thanks

Need help as son as possible, thank you in advance.
Your Apache user does not have the rights needed to write to your database.
Modify your settings.py so that it shows an absolute path for your database, for example:
DATABASE_NAME = '/var/www/dashboardapp/whatever/path/db.sqlite3'
Then type the following commands at the Linux prompt to set the correct privileges:
chown www-data /var/www/dashboardapp/whatever/path/
chown www-data /var/www/dashboardapp/whatever/path/db.sqlite3
go to your project directory, just share permission with IIS user and that should do the job - if you have deployed on IIS windows server

Anybody experienced the same thing and any hint to solve it?
I had a suspect that I need also to subclass the UserCreationForm and UserChangeForm used by the original UserAdmin, but if it is the correct way, I honestly don't see the advantages of using a custom user model rather that create a one-to-one model (e.g. Profile) to extend the original User.
Thanks

Good day, Luke!
Please, look at django docs: https://docs.djangoproject.com/en/dev/topics/auth/customizing/
Just check, what model you are using: CustomUser or AbstractBaseUser.
As I can see, now it's AbstractUser.
Just starting with Django and have began creating an application for test purposes. However, when I specify rollercoasters to ManyToMany and add an instance of a Park via the admin UI I get an:
IntreityError, rollercoasters_id may not be NULL
I have just completed a book on this and the code is more or less exact as the books (the code works in the book).
What am I doing wrong?
The application works when I have ForeignKey instead of ManyToMany

You can't just swap between a foreign key and many to many field. If you have a foreign key, Django creates a database column e.g. rollercoaster_id. If you use a many to many, Django creates an intermediary join table.
To switch from a foreign key to a many to many field, you must do one of the following:
drop the tables and then run syncdb so that Django recreates them. You will lose any data.
manually update the database schema yourself, using the output of the manage.py sql command as a guide
use the schema migration tool South.
I included an ImageField field in my "sponsors" model, which is set to save the uploaded image files to my_app/static/uploads/sponsor_logos, and when I try to save a record using the admin interface, I get the following error:
OSError at /admin/sponsors/sponsor/add/
[Errno 13] Permission denied: '/static'
Here is my model:
from django.db import models
class Sponsor(models.Model):
name = models.CharField(max_length=200)
level_choices = (('Gold', 'Gold'), ('Silver', 'Silver'), ('Bronze', 'Bronze'))
level = models.CharField(max_length=10, choices=level_choices)
logo = models.ImageField(upload_to = 'sponsor_logos/')
class Meta:
ordering = ["name"]
def __unicode__(self):
return self.name
And my media root is set to:
MEDIA_ROOT = '/static/uploads/'
Here is the traceback:

I ran chmod 777 on the directory my_app/static/uploads/sponsor_logos, so it should be writable. Also, I ran python manage.py shell and, from there, created a new text file in the sponsor_logos directory, so the directory does seem to be writable. Why do I keep getting this error?
To resolve this issue for me was the same as #user1933387. I had formatted my computer and changed the naming convention of where my folder was.
for example:
Old folder was called: /Users/jimmy/...
New folder was renamed to: /Users/jim/...
/Users/jimmy no longer exists and it couldn't write to it so it throws the permissions error rather than a directory not found. Confusing when trying to dig into this, especially if you don't notice error right after a change like that but if the path doesn't exist, this is the error you get.
