Add values to django database from an external python streamlit app - django

I have a streamlit app that runs machine learning on an image given by the user. I also implemented authentication using django along with a gallery type app that allows users to view stored images if logged in. I want to add the ability to automatically apend the image uploaded on my streamlit app to the database if the user is logged in. What would be the best way to do this?
I tried importing my create view into the streamlit app and defining the variables manually. I also tried to import the model and work with that but I couldn't get either of them to work. I also shifted my streamlit app into the same directory as the django app to prevent PATH errors.

How can I redirect a user to Django auth from a webpage not a part of the Django app?

We have a R shiny app server to whose links will be present on our Django website. However we want the user to be taken to login(and check if they have the permission to access) before they are able to access the R shiny app page.
We could embed the Shiny app using an iframe on our site, but then anybody can copy the src link and use it to access shiny app without login, later.

Hosted django app on heroku, how would I go about creating images in models

Hi so I have an app where for every model object I create an image and so far I've made it so you manually create the images for multiple objects through an admin action. When I've run it locally it saves to the media folder but now I've deployed it to Heroku, so right now they're created but disappear into the ether. I want the user to be able to print the images so where do they go?

Deploying Django admin and Site as different applications

Is there a way to deploy Django Admin and your main application separately, though both of them sharing the same Models / Business logic services.
I come from Grails background where you can create a plugin which can hold your Entities and common business logic and that plugin can be utilized by other application deployed and scaled separately though using the same Database. You don't have to repackage your plugin again for every change rather its just sibling folder to your other projects.
Can I achieve something similar with Django?
Assuming a typical setup, in order to be useful Django Admin needs access to project's apps and their models.
So a setup that you've described would require at least:
simple URLconf with just Django Admin
models and their Admin bindings for all apps that need Admin
settings with database credentials
Even if your models and Admin bindings are not dependent on other parts of the codebase,
extracting the above components to a separate project and then keeping everything
in sync sounds pretty hard.
Summarizing: I would say it's hard but possible if it's something that you really need,
but Django Admin hasn't been designed with such use case in mind.
Django admin is actually separate from the main application by placing it on its own url. Even if they know the admin url, users cannot log in to the site's admin unless they have already been assigned Staff status via the admin. You can set the admin prefix to anything you want, so if you want to "hide" the admin login page, just make it something long and random (good for security too), and basically no one but those you tell will even know where the admin site can be found.

React + Django app refreshes for every deletion in Django admin panel

I'm not really sure what to share (i.e. which part of my application code) as I'm still a beginner with React so please bear with me.
I have a React application running on top of a Django application. Basically, there are Django Admin Panel URLS, REST API URLS in Django, and one path to catch all paths that don't belong to the first two groups.
I have a page (or a React Container) that calls Django's REST API to query all entries in the users DB Table. This part is okay but what I've noticed is, everytime I manually delete a row in the Django Admin Panel, the whole page refreshes. What are possible reasons for this?
By the way, I'm using Redux as well to manage the whole application state.

create an admin's like application in django

Im really confused about what is all i need to consider for creating a django aplication with almost similar functionality to it's own admin.
The index page should deploy the list of models the user has access to modify or create...almost the same as when you put admin.site.register(MyModel) but with permission restriction. Im not sure how should i ckeck permissions, and show 1 ,2 or many "ModelAdmis" on my main page.
btw admin users are redirected to the admin index page, non-admins go to my page
Before you consider creating a django admin from scratch, you should read the answers to this question Django Admin app or roll my own?
I couldn't find any resource on how to create a django admin from scratch, but here's what you should do if this is your first time overriding a framework's functionality (in my humble opinion):
Understand and make sure you are comfortable with the django admin app
start from the docs https://docs.djangoproject.com/en/1.7/#the-admin
Head over to the django admin app source code so you can start reading the internals of the functionality you want to implement/override in your new admin app.
source code can be found here https://github.com/django/django/tree/master/django/contrib/admin
(this may involve reading other apps source code too)
After those two steps you should have an idea on how the admin app is implemented and it's dependencies, then you can start creating your custom admin app.
an example on how this may go can be found in this qestion:
How to override Django admin's views?
If you are building something new, try to separate the UI from the backend. You can build your UI using react, angular or whatever and interact with django using the API. To build the API you can use the Django Rest Framework.
Don't use the Django Admin as a public interface. Use that only for the admins!
If you start to use the Django Admin as interface for your public site, you'll fight with the package to tailor and secure the views to avoid destructive actions. What happen if you forget a readonly field? What if the user deleted something ON_CASCADE?
Building the UI you are totally free and you can customise easily everything without fighting the django admin package (it's awesome package but is not provided for public use)
