I already have an application using PostgreSQL as db. I want to build a service using Django. Tried "inspectdb"... but it is giving an expection:
Traceback (most recent call last):

Figured out the issue.
Apparently, the db user didn't have sufficient permissions.

Are you following a tutorial? If so, please share it with us. There may be a problem with your python installation. Please delete all python installations on your computer and install the latest version. Then create django project again.
I m trying to create superuser in Django (1.11) on Python (3.6.4) on Mac (10.13.3).
After entering username, I'm pressing enter. enter won't take me to next input.
$ python manage.py createsuperuser
Username (leave blank to use 'neon'): admin^M^M^M^M^M^M^M^M^C^CKeyboardInterrupt
The above exception was the direct cause of the following exception:

As mentioned in comments, both ctrl+j and running command in new terminal worked.
I want to use djangular in my django project but I have a problem.
the problem is that when i want to create djangularapp in django project with this commant python manage.py startangularapp djangularTest it shows me the below error:

Read your error traceback once. The first line clearly shows that instead of using python manage.py startangularapp djangularTest you used python manage.py startangularapp djangularTes t.This means that django reads two name values.
I have a local python environment working, but when I try and load in initial data.
python manage.py loaddata initial_data.json
I get an error about "RemovedInDjango18Warning"?
I am not a python dev to say - so this error is new to me.

You should rename get_query_set to get_queryset in SearchManagerMixIn. Can you paste the definition of the class if you need more help.
