Hi. No, Django cannot replace javascript. Django works in the backend. There are some projects bringing Python to browser. One of them is brython. Certainly there are others, too. On 15 May 2018 at 07:48, Chekib Gmt wrote: > Hello, > I would like to know if the django framework can replace

I'd say you're missing a service layer. It's known as a good practice to not have "business rules" in your views. IP lookup should be done in your view anyway, because it's a "web related thing". The `save_the_lead()` and email sending should be in the service layer. Extending a little bit and t

I hope you already got this solved. If not, there's a way to achieve what you are looking for. Get settings.MIN_SLUG_LENGTH from an environment variable. Use it in your settings.py: MIN_SLUG_LENGTH = os.getenv('ENV_MIN_SLUG_LENGTH') You'll need to set ENV_MIN_SLUG_LENGTH before running your test
