Clearing the doubts of django app with questions. when try to make a marketplace for software apps.

✅ Can I create an app without a Django project?

• Yes, technically you can run:

  django-admin startapp myapp

  But it won’t be usable unless added into a Django project that provides settings and context.

---

✅ Can I make or install an app inside another app?

• Django does not support apps inside apps directly.

• Instead, structure reusable apps at the project level, and install them via INSTALLED_APPS.

---

✅ Can I install a package only for a specific app?

• No, Python and Django don’t support per-app packages.

• All dependencies go into the global environment or project requirements.txt.

But you can document per-app dependencies in llm/requirements.txt for reuse.

---

✅ If I reuse an app (like llm) in another project, how do dependencies follow?

• You need to:

  • Package the app (llm) as a Python package

  • Include its dependencies in a setup.py or pyproject.toml

  • Then install it via pip install in the new project

---

✅ How to make a Django app a reusable Python package?

Use cookiecutter-django-app:

pip install cookiecutter
cookiecutter https://github.com/pydanny/cookiecutter-django-app

This generates a ready-to-publish, reusable app with packaging tools, tests, and structure.

---

✅ Can Django packaged apps show models in Django Admin?

• Yes, if you include:

  from django.contrib import admin
  from .models import MyModel
  admin.site.register(MyModel)

  And the app is in INSTALLED_APPS, the models will show up in Django admin.

---

✅ What is the role of a Django App in MVC?

Django Term	MVC Equivalent
views.py	Controller
models.py	Model
templates/	View

🔁 So a Django app wraps all three — it’s a complete MVC feature unit.

---

✅ What was in the image structure?

Apps like RelayApp and FileHandlerApp were reusable Django apps installed across multiple projects. They were treated as dependencies.

---

✅ Is there a “launcher” to run a single Django app?

• Django needs a project for INSTALLED_APPS, DB settings, etc.

• But you can:

  1. Create a minimal project wrapper just for one app.

  2. Use a custom runner script (standalone Python file).

  3. Dockerize each app for microservice-style use.

---

✅ Are there alternatives to cookiecutter-django-app?

copier-django-app	Modern templating alternative to cookiecutter
django-app-template	Community skeleton
pyscaffoldext-django	PyScaffold-based setup
django-shared-apps	Shared/tenant-based app architecture
