Make permissions for the folder that contains the Database will solve the problem.
Also, you can run it as administrator to solve problem.

django & send_mail in docker leads to SMTPServerDisconnected

I setup a google email backend for django and all is working fine until i run the whole stuff in docker-compose containers.

Any idea what's going wrong here? Why is it disconnecting in a container?
Just figured it out:
In the docker-compose.yml i have something like this:
env_file:
- ".env"
The content of the .env was:
key = value
This runs great on a local machine loading the .env file first.
However docker needs a more strict format:
key=value
No spaces!!
The error was that my EMAIL_* settings wasn't set correctly with spaced key/value pairs

Mailgun 404 error with Pythonanywhere

I'm trying to use mailgun in my Django project hosted on Pythonanywhere.
In my WSGI file, I have:
os.environ['DJANGO_MAILGUN_SERVER_NAME'] = 'https://api.mailgun.net/v3/sandboxnumbersomething.mailgun.org/messages'
os.environ['DJANGO_MAILGUN_API_KEY'] ='mykey'
and my settings are:
# EMAIL
# ------------------------------------------------------------------------------
DEFAULT_FROM_EMAIL = env('DJANGO_DEFAULT_FROM_EMAIL',
default='Apitrak <noreply#apitrak.com>')
EMAIL_BACKEND = 'django_mailgun.MailgunBackend'
MAILGUN_ACCESS_KEY = env('DJANGO_MAILGUN_API_KEY')
MAILGUN_SERVER_NAME = env('DJANGO_MAILGUN_SERVER_NAME')
When my app fire an email (for example at signup), I have a 404 error:
MailgunAPIError at /accounts/email/
<Response [404]>

I've tried a curl in the virtualenv of my WebApp:
curl -s --user 'api:key-NUMBERS' https://api.mailgun.net/v3/NUMBERS.mailgun.org/messages -F from='Excited User <excited#samples.mailgun.org>' -F to='vincent#vincentle.fr' -F subject='Hello' -F text='Testing some Mailgun awesomeness!'
And this works OK.
The setting DJANGO_MAILGUN_SERVER_NAME should be a domain name, not a url.
Try the following:
os.environ['DJANGO_MAILGUN_SERVER_NAME'] = '<sandboxnumbersomething>.mailgun.org'
From the readme:
Replace SERVER-NAME with the last part of your "API Base URL" (e.g. https://api.mailgun.net/v3/<your_server_name>), also found in your Mailgun account details.

serving static files from heroku

I have created a simple portfolio website on manojmj.herokuapp.com
I want to host the images,css etc on heroku itself and does not want to move to s3 since its only 800kb in size.
My site is running fine and displaying the images correctly on my local dev server(127.0.0.1:8000)
However, on manojmj.herokuapp.com I can see only the markup and no images.
When I click the image url I get the errror:
