How to run multiple sites from one instance of Django? - django

I am using Django as the back end and Nuxt as the front end, with Postgres as the database. I would like to have different tables/databases for each domain.
The Django code and the Nuxt code will be the same for all sites.
The way the app is set up, it requires different domains to have different databases or at least different tables.
At the moment, I am thinking I need to create a separate installation of Django/Nuxt for each domain. But I am wondering if there is a better way?

Setting up different Code bases for every domain is not a good idea at all. I had an app that was set up that way and soon we were struggling to maintain the same code and DB structure for all the different domains. After a few domains, it will become tricky.
I would suggest developing a multi-tenant SAAS based app, where you can have multiple tenants running the same Django/Nuxt code but having different schemas in the Postgres, So your database for different domains will be completely separate from each other. I would suggest using django tenant schemas for this. Even if it takes you some time to set it up, I would suggest doing it. It will save a great deal of time for you in the future.

How to break a django website into microservices

So, I am new to this "monolith vs microservices" architecture debate and I have pretty much understood most of it. From my limited understanding I get it that in microservice architecture each feature(lets say) is a separate app. Now I need some clarification with respect to django for implementing microservices. Heres my question
Should I make every microservice aka the app a different django project altogether OR should I make every app aka the microservice inside one django project and keep them isolated (as in loosely coupled) ?
Microservice architecture simply states that your each service should be independent of each other.
Its also not necessary to create one micro-service in java and one in python since they are not related.
So yes, ideally your each micro-service is a separate django project.
The best way to break this, first list down all the possible modules in your site or app.
Then go through :
https://microservices.io/patterns/decomposition/decompose-by-business-capability.html
https://microservices.io/patterns/decomposition/decompose-by-subdomain.html
These are two recommended pattern of how you should divide modules / domain into micro-services.
well, you can use database routers in django ... that does the trick ... one wSGI file per app communicating with your NGINX server
The main purpose of micro service is to serve the specific business, for example you are running a cloud kitchen then Django project can have many sub projects under one master project or you can run each project as separate service, it up to you.
Service
backoffice
finance
rider
kitchen
now we will set the url for each service like
Endpoints
backoffice.mycompany.com
finance.mycompany.com
rider.mycompany.com
kitchen.mycompany.com
Once our app is up the service load will not effect other service.
The microservice should be completely independent so it should not belong to one Django project. You should be able to deploy each service independently with its own database, so even you split the project into separate apps they still share one physical database and you can not deploy them separately. Therefore, you could potentially create separate Django project for each 'microservice' but this does not make much sense. You put lot of overhead for creating a microservice and also using Django framework is not a best choice for MSA , have a look at Flask.

Django REST and React implementation model

I am currently creating a website hosted by Django. I plan to use React as my frontend framework. I have done some research on putting them together but most say that I should go for the SPA model and have separate web servers for frontend and backend. The problem is that I wish to use apache as a prod server with django and avoid having 2 separate servers. I have read about the hybrid model and having django serve static files with react.
My Biggest concern is security as I have already setup apache for security and I aware that node.js is somewhat insecure.
What would the best approach be. The separate SPA model or the hybrid model.
I'd say it's okay to go for hybrid model if the project is small and you are the only one working on it and you only want to make things done. I think it's kinda messy to create apps like this unless they don't really worth the time.
But if it's a big project and more than one developer is working on it or will work on it then i highly recommend going with separate web servers one serving frontend app and one django app.
Also note that you don't really need 2 different servers. You can use one server for both and use 2 different which is still not necessary and you can use one web server to serve both.
And security not something that different models can cause to downgrade or upgrade. It's up to you to configure the server and write both frontend and backend apps secure enough to do the work for you.
There are more than one web servers that are as secure as they can be and they work with both django and react pretty well. I used nginx many times to host both django and react apps and i had no problem causing by nginx itself whatsoever.
And for last piece of advice if you will; Creating good quality apps requires a lot of time and energy, working with different technologies that do really good for what they are made for and if you are planning to be a really good developer you should come out of your comfort zone and adapt with new technologies that comes out and they are coming out pretty rapidly which requires you to learn constantly and do things in way you are not used to yet and making things work even if they doesn't seem to be good together at the first look.

Subdomain hosting with Django + Nginx +Gunicorn

I am developing a web app using django for server-side. It has clients in android, ios and frontend. I was thinking of using subdomains for differentiating the urls of these clients. The differentiation is due to the fact that responses to urls are different for different clients.
I was hoping of being able to do using subdomains like android.example.com, ios.example.com...etc. My subdomains are fixed.
Can you help regarding what approach I should take to achieve this. Some options I have read are
Hosting two different project with same database.(Looks quite good for me, but may not be the optimum)
Hosting on same instance using sites framework.(Not sure as to how good this option is)
Hosting using virtual-host(Really Not able to understand how to achieve this).
Using a Sub-domain Middleware, as mentioned in many of answers and also in some Django Snippets.
Please help me with the best option and if possible with links to some tutorials as to how to achieve it. Thanks.
"Using the sites framework" is somehow the same as hosting two projects with the same database. If you would use the sites framework you would have seperate instances for each subdomain which share the same code base and data base, but have to differ in one setting in the first place, which is SITE_ID.
If you're able to run multiple instances this for sure has some advantages:
You don't need additional processing via a middleware
You can easily choose different settings for each site, eg. different template paths, use different middleware etc, even customize urls per project if necessary
You're doing already some kind of load-balancing, as you're directing requests to seperate instances, also if one site crashes it shouldn't affect the others
If you can only run one instance I guess your only choice is using something like a middleware, eg. django-mobile then is maybe something to look in as it offers you some good toolset for determining the type of client etc...
But besides that note that it might not always be the best practice to have seperate domains with the same content when it comes to SEO.

django app engine multiple domains, multiple settings files

I'm new to Google App Engine and am trying to port my Django application to use that. I haven't been able to find too much on this and don't think multitenancy is what I'm looking for (seems to be for more or less identical apps with different data sources?), but my scenario is this:
I have multiple domains and currently have different settings file (with seperate WSGI files) which works great for my current Apache configuration, but I'm trying to migrate over to GAE and can't seem to figure out how to do something similiar based on domain name? Really, all I critically need is a seperate urls file based on the domain name (datastore is the same on both), although it would be ideal to have a separate settings file so I don't have to load unused apps, preprocessors, etc on sites that don't need them.
You can possibly have two different versions of the app, they both will use the same data store, since source code of both versions can be different, you can specify different configurations/settings for each of them.
coming to accessing different versions, you can either route through your dashboard/domain settings and/or fine tune it with help of traffic splitting
hope it helps

Multiple Django Instances on one AppEngine Server

For our project we host both the website and the actual webapp on one AppEngine instance. I separated them both nicely in different projects, but they all share the same settings file. It's becoming more and more clear to me that these should actually be independent django instances as they use different settings for middleware, template loaders, etc.
So I tried running two django instances on the same server (different handlers), but because django uses global variables for caching all over the place, which the AppEngine runtime caches between requests, I couldn't get this to work reliably. Did anyone successfully do this before?
Since you can run multiple app versions simultaneously, I would put this independent django instances in different app versions.
