When you create a new post with a title == 120 you've got an error. It's occurred because of slugfield in models.py. You need to add max_length = 120 to fix it. It's confusing for such begginers as me.

Hello Sir,
I am having trouble when I want to make a post. After I press the button 'SAVE' I get an error .
/posts/models.py", line 30, in upload_location
new_id = qs.last().id + 1
AttributeError: 'bool' object has no attribute 'last'

I try to put "www.xxx,com" twice ,but I got the same page "Success",
I think it would be better to change the post function in HomeView
'''
def post(self, request, *args, **kwargs):
pform = SubmitUrlForm(request.POST)
context = {
"title": "Kirr.co",
"form": pform
}
template = "shortener/home.html"
if pform.is_valid():
#print pform.cleaned_data
new_url = pform.cleaned_data.get("url")
new2_url = validate_url(new_url)
obj, created = KirrURL.objects.get_or_create(url=new2_url)
context = {
"object": obj,
"created": created,
}
if created:
template = "shortener/success.html"
else:
template = "shortener/already-exists.html"
return render(request, template ,context)
'''

                    This option has no effect.

why manage.py is not creating

Since we are using 1.9, why are we not using Class Based View (as in Django Docs) ?

when you try to make new post upload_location give the instance and use its id for making a directory
but at first it is no instance and the id will be NONE and you app makes a none name directory to store that picture
it is so bad :(

Hi .. I am having trouble when I want to make a post - . After I press the button 'SAVE' I get an error .
The console looks like this - I'm using a pyodbc database - I have checked the 'id' is there.

Hi, I am having trouble when I want to make a second post.

File "/posts/models.py", line 37, in upload_location
new_id = 1
qs = PostModel.objects.order_by("id").exists()
if qs:
new_id = qs.last().id + 1
AttributeError: 'bool' object has no attribute 'last'

Can anyone help me with this?

Hi guys! see posts/models.py

user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1)

The problem is, please refer to django1.9 docs, syntax for AUTH_USER_MODEL = 'myapp.MyUser' , which myapp is one of the app in INSTALLED_APPS and MyUser is Django model that use as User model, does that means you have to create a user model in Post app or create a new app such as user_profile containing user model??? So I'd rather choose a user model from django.contrib.auth until the new app and/or related models created.

Another problem is AUTH_USER_MODE not set from the beginning, If you intend to set AUTH_USER_MODEL, you better set it before creating any migrations or running manage.py migrate for the first time, otherwise, you will have dependency issues. see post/migrations 0002 and 0003
