Connection to Django default failed - python-3.x

Question

So i'm using Pycharm and have installed the Django framework and Postgres. When I initially setup the default Django DB to point to the Postgres database everything works fine.
The problem occurs if I make any changes to a table, meaning the table structure, then try to synchronize the database in Pycharm I'm getting an error message saying "Django default - Connection to Django default failed:"
Here is my setup:
OSX Maverick
Postgres 9.3
Django 1.5
Pycharm 3
Python 3.3
Any assistance someone can give is greatly appreciated!

Answer 1

It looks like Django can't connect to Postgres. You might just need to tweak your settings.py file to make sure you have the correct postgres DB info in there.
In any event here is a more complete guide:
To get django working with Pycharm
Make sure you have followed how to install django correctly
https://docs.djangoproject.com/en/dev/topics/install/
2.go to the project drop down box and click edit configuration
then make sure
host = 127.0.0.1
port = 8000
make sure it is using python 3.x.x as the interpreter rather than python 2.x
In Pycharm go to Preferences —> Django
make sure it is enabled
and then:
Django Project Root connects to the root of your project (usually where manage.py is)
Settings points to your settings.py file inside your project
Manage script points to manage.py
make sure you have installed psycopg2
if you are using python3 that means using pip3 not pip (pip is for python 2.x)
pip3 install psycopg2
Edit your settings.py file as below
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'polls',
'USER': 'lms',
'PASSWORD': '',
'HOST': '', #note an empty string means localhost
'PORT': '5432',
'OPTIONS': {
'autocommit': True,
}
}
}
note the default postgres port is 5432 - if it is not connecting using that check this post:
postgresql port confusion 5433 or 5432?
