Two django projects with common userbase , authentication and sharing of key functionalities - django

I'm building a Django v3.2 project that requires merging of 2 projects(social app and ecommerce) - both of which are separate open source django projects. The end goal is to share users, posts and a common user registration and authentication process and keep a common database for both. Project 1 has a 5 docker containers(api backend, worker,scheduler, sql db, redis db) and project 2 has 1 docker container(that has a frontend sandbox ecommerce website). I came across this post while searching which is similar :
How to make two django projects share the same database
Based on the post share above, My core question is :
While I'm using 2 separate projects that run their own docker containers, what changes will I have to make so that
Registration, Authentication & Users are common
Functionalities are shared.
Essentially, I would like to import modules from project1-->project2 and project2-->project1 and design additional functionalities as per need.
I initially tried copying files from project 2 into project 1 so that the project1 social app and functionality is just extended. But I'm running into all sorts of problems. Here is the question pertaining to the same :
Python3.10:ModuleNotFoundError: No module named 'commerce'

Django Project with TWO frontend Vue3 apps

Django project has two apps. Customers & Operations.
I want to separate access to the apps with separated front ends. The user authorization strategy I will follow to achieve this is where I am stuck. My research has is advising against two user models. And I recently found out about Proxy models.
I need opinions on best approach for above requirement.
the access links requirements are e.g
app1 customers.example.com
app2 operations.example.com
Customers will have its own set of users and authorization.
Operations will have its own set of users and authorization.
Operations app will create Customers[eg Cust_X, Cust_Y].
Cust_X will have users[eg User_X1, User_X2]
Cust_Y will have users[eg User_Y1, User_Y2]

django frontend and backend seperation for security

I have written a web app in Django with usual Django project structure. At my company, they want to separate front end and backend on different servers. Frontend server will have internet access and backend will have a strong firewall and no net access. What I understand from this concept is, they want to separate back-end (view.py) from Django project to shared folder (shared with the back-end server). Is it possible to separate view.py file to the different folder and then import it to project?
Also another question on the same topic. Does Django have good security or security ideas like this are required to protect against hacking? What measures should I take to ensure protecting my backend against hacking if I can't separate backend? (I have already implemented LDAP authentication, using CSRF tokens and all pages are protected by #login_required)
What you can do is creating two projects, one for serving your "front end" with a disabled admin (simply remove the 'admin' in your project's urls.py) and another one for managing the django admin and only accessible from inside your company's network.
Make them share the same database where the database server should only be accessible from within your company's network, as well. Be sure to only create the models only in one app, preferably in the front end app as you might want to have user input handled by django forms.
Register the "front-end" app models in the "back-end" project via the admin.py in the "back end" app. That should allow you accessing the data stored in the db.
When it comes to third party apps and plugins be sure to check their urls.py (and disable the admin in case), models.py and admin.py in order to implement it in your "back-end".
Hope that helps!

Working on django projects, where I have multiple projects and multiple databases, I want to access all databases in everyapp

I have 3 projects (A, B, C) and 3 databases (DB1, DB2, DB3). I have defined Model common in project A and want to access same model in Project B. I want to access every database with each application. I don't know how to configure settings files so i can use every database. I tried django's multi-db but didn't get what I need.
Project A has Model UserAttributes(), how can I use this model in Project B or project C as a shared database?
Have you think about interacting between applications using an API? Give a try to django-rest-framework. You can have an API view in application A that receives GET and POST requests to query and alter the common model.

Moving from PHP/Laravel to Python/Django

I want some clarity. I want to learn more about django and use it as replacement for php/laravel. But the default structure and convention of django confuses me a bit.
My PHP/Laravel project has 3 parts:
- Administration
- Core (Web app for regular users)
- API Service (REST-API for mobile apps)
However all of controllers, models and views are contained in a single Laravel application. I separated Auth, Admin, Api controllers into their own folders/namespaces.
One thing that confuses me is the default Django structure 1 view 1 model file. How should i go about reworking this application in Django should each of my controllers be a separate app in my django project or should I have same approach as in Laravel. 3 Django apps in one project one for admin one for core and one for api ? Where should I keep my models than since in Laravel all models are used by all 3 parts ?
My current structure:
./
./controllers/
./auth/
LoginController.php
RegistrationController.php
...
./admin/
ReportsController.php
UserController.php (Admins overview of all users)
...
./api/
HealthController.php (API CRUD for Health resource)
ExerciseController.php
HomeController.php
UserController.php (Regular users profile page CRUD)
...
./models/
User.php
Health.php
Exercise.php
...
One thing to remember about Django is that an app in Laravel doens't necessary translate to an app in Django. In Django, there are projects, and each project can have any number of apps. For example, I have a "Backup Admin" project where I manage a lot of the day-to-day issues of managing a tape backup environment. I have an app for media (that has 3 models, one for regular media, one for cleaning media, and one for media that we want to exclude from tape ejections). I have an app that represents the backup images, and another for backup jobs (to check status codes). Each sub-piece of my project goes into another app.
If I wanted to do another Django project that had nothing to do with backups, I'd make that a completely separate project, which would have a separate directory structure from my backup project. It'd have it's own urls.py, settings.py, etc.
Regarding the models piece, I put all of one app's models in the same file. For example, in my media app, I have models.py, which contains all three models that I mentioned above. This is completely optional, but I do it just so while importing these models into other parts of the project, I don't have to remember what the file names are, instead I can just do this:
from media.models import CleaningMedia,Media,EjectExclusions
Otherwise I'd have to have 3 different import statements if they were in different files. It's completely possible, but based on your preferences.
Regarding the controller, Django lets you do it either way. You have a project-wide urls.py file that you can use to control all of the traffic, or you can have separate urls.py files in each app to control that app's traffic. I prefer a single file, but that's just me. Personally if you have a lot of controller entries, you should probably split them up into app-specific urls.py files, just to keep it clean, but again, either method would work. I think of maintainability (especially with respect to teammates having to support it) when I make these types of decisions.
The admin interface is built-in, so there's not really an app for that, but you can decide which models and which apps have entries on the admin interface quite easily. Each app has an admin.py file that controls this.
A side note, for a RESTful API, you also might want to consider Django Rest Framework. It's a great piece of software, and the documentation (and tutorials) are very helpful.
Edit:
The 1 view/1 model thing again is just preference. You can have as many files as you want. The only trade off is when you import them into other files, you have to specify the file you're importing it from. That's really all there is to it. I know people who have a views/ directory, and inside there, have separate files for each view, keeping each class/function separate. Totally a matter of preference.

How to structure a project directory in django?

Suppose you are building a Google website. (ok big dream)
Google has web search/youtube/email/news/etc ..
For this site, I'd like to structure my django directory like
Google/
search
youtube
email
news
and so on.
How do I structure such a site?
Create an app for each even though I'm not expecting to publish any of the category as an app?
Where would a common stuff (such as user model, utility modules, decorators..) would go, create a common_app?
Applications are reusable components for a django project that revolve around a central purpose. Applications don't need to map directly to your url structure of the website. While there is a standard structure for a django application to tie in with some of the management commands, such as tests.py, models.py, static files at /static/ you don't need to have any of it to be an application. For example, South is a popular django application used to provide database migrations. It adds a few management commands to manage.py.
When you are adding functionality and it doesn't map directly to the purpose of the application, just create a new one. So instead of thinking of it a a common_app, think about what the purpose of the application would be and how it might be utilized by your other applications.
In my projects, I tend to create a base application to handle the base template and static assets that are used in the base template. I'll create an accounts application to handle the user model and implement things like password reset. To deal with global notifications from any part of my site, I'll create an alerts application. The list can go on for a lot of the common functionality, but it's grouped in a way that revolves around a function and written as if it would be distributed.
So, in your specific case, you'll likely have at least an application for each of the domains such as search, youtube, email, and news, but also an application for each common component you might want to use across your core domains.
