How can a Django web app in a centos Docker container send emails via a Windows 10 host?
I have a Django web app running in a Unix (Centos 8) Docker container, and this app is supposed to send emails. Currently I am running the app, including other Docker containers, on my Windows 10 laptop for development and manual testing. But eventually it will run in an AWS EC2 instance. I suspect that in AWS I can just use Amazon's SES ("Simple Email Service"). But I would like to be able to email in Development mode too. I set up an SMTP relay Docker container, with port 25 mapped to host port 25, and running an emailer called Postfix (a successor to Sendmail), and tried to configure it. But, although the SMTP relay mode configuration of Postfix is supposed to be pretty simple I wasn't able to get the perishing thing to work. I'm not sure if this is because my Postfix config is defective somehow or because Windows 10 is not playing ball. Any ideas? P.S. I case it helps, the following are the Postfix environment variable values I defined. If anyone faced with the same problem finds this page, please don't rely on these values, as some or all may well be nonsense! ENV RELAY_MYDOMAIN=jrsurveys.com ENV … -

Django Web Form - Update YAML File Variables
Is it possible to update YAML file variables from a Django web form? I ask because I need to update a YAML file based on user input without giving them access to the YAML file itself. I was thinking that a Django web form would be suitable for this task in my brief reading of it, but I'm not sure if this is possible or not and if it's worth researching any further. -

Django: cannot connect to web with domain name (but fine with IP address)
for the life of me I cannot figure what is going on with this deployment. I am using EC2, route 53 domain(freshly acquired a domain), nginx and gunicorn with supervisor. similarly to this post How do I deploy Django app to (AWS) domain name?, I can acess the app in the web with the IP address but not with the domain name. it gives the error : 'this site refuse to connect'. But when I ping the website with nmap on the port and IP address and also with the domain name i get a positive response. Here are my ALLOWED_HOSTS in settings.py ALLOWED_HOSTS = ['xx.xxx.xx.xx', 'mysite.net', 'www.mysite.net'] nginx django.conf server { listen 80; server_name xx.xxx.xx.xx mysite.net www.mysite.net; location / { include proxy_params; proxy_pass http://unix:/home/ubuntu/exostocksaas/app.sock; } location /static { autoindex on; alias /home/ubuntu/exostocksaas/inventory4/collected_static/; } } Really I cannot figure out what is going, could it be that the domain has not propagated yet, but why would it give me such error then? I hope that someone has a clue, I am looking everywhere and I feel like I might up accidently breaking my setup! -

Django how to put togheter form, crispy and ajax call

I want to insert the form not with html code, but with crispy_forms. How can I do it? I tried but the ajax does not work. Could you help me? -
Project structure Django/Plotly/Websocke - display data from DB with Plotly
I'm just getting started with Django, Plotly and SQL so this question is relatively general, but I'm struggling to get my head around the general structure of a project i'm working on. I've set myself a learning task of setting up a page that displays charts of asset prices (Apple stock, Bitcoin etc). I will then build this out to have user accounts and various other functionality. This leads me to a few questions: 1) Should I store the price data etc in the same database as Django is using for the rest of the page or is it best practice to separate these out. I currently have 'default' set to a local postgres db, should i set up a new db for all the asset price data? 2) I currently plan to connect a websocket stream to receive the live price data. Each time a message is received I then write that data to the database. My plotly charts would then update. Is that the most efficient way to do this or is there away to connect the ws directly to the database without the connector? This database will be written to at potentially the same time the page … -
Django dumpdata into docker
I have a docker container where is running a django app. I'm trying to backup my database using cron. The django app is located in /usr/src/app. This is my crontab file:*/1 * * * * cd /usr/src/app && python manage.py dumpdata>dump.json The issue is that the dump.json file is created but nothing is in it. I tried to run directly python manage.py dumpdata>dump.json bash in my container and it actually works (dump.json is filled with my db content). Could you help me please. Thank you.
