Choosing the right hosting provider depends heavily on your requirements .While many providers provide free Django hosting , you should only use it for testing purposes or for playing with the provider's infrastructure or … -

How to fix Django’s HTTPS redirects in nginx
You deploy with nginx and Gunicorn and your site uses HTTPS. If Django occasionally returns HttpResponseRedirect or similar, you may find that the redirect sends you back to HTTP. Here’s how to fix it. In the nginx configuration (inside the location block), specify this: proxy_redirect off; proxy_set_header X-Forwarded-Proto $scheme; The proxy_redirect off statement tells nginx that, if the backend returns an HTTP redirect, it should leave it as is. By default, nginx assumes the backend is stupid and tries to fix the response; if, for example, the backend returns an HTTP redirect that says “redirect to http://localhost:8000/somewhere”, nginx replaces it with something similar to “http://yourowndomain.com/somewhere”. But Django isn’t stupid (or it can be configured to not be stupid), and it will typically return a relative URL. If nginx attempts to “fix” the relative URL, it will likely break things. Instead, we use proxy_redirect off so that nginx merely passes the redirection as is. The second line is only necessary if your Django project ever uses request.is_secure() or similar. It’s a good idea to have it because even if it doesn’t today it will tomorrow, and it does no harm. Django does not know whether the request has been made through … -

Transcoding with AWS- part five
This is the last blog post in this series - the only thing that has to be done is telling the user that file he or she uploads is processed. It will be done by writing custom message application. Tabel of Contents: How message application should work Implementation in django Other blog posts in this series How message application should work From previous post I know that the last point of my application flow is to inform user that file is transcoded and ready to download. To do such thing I have to display message on every webpage that current user is. This message should have information about which file was processed. First I wanted to do this with existing django messaging framework but as it turns out is works only with request. As I decided to show message for different users as long as they dismiss this information I had to write my own small application. Implementation in django In my newly created application I created following model: from django.db import models from django.contrib.auth.models import User class Message(models.Model): text = models.CharField(max_length=250) read = models.BooleanField(default=False) def __str__(self): return self.text I decided to display my message only when it wasn't read. … -

How I Deploy Django Day-to-Day
There are a lot of ways to deploy Django so I think it is one of those topics people are really curious about how other people do it. Generally, in all deploys you need to get the latest code, run migrations, collect your static files and restart web server processes. How yo do those steps, that is the interesting part. In todays video I go over How I deploy Django day to day, followed by some other ways I have done it. This is definitely a topic you can make as easy or complicated as you want.
