Django template not displaying React component
I have installed all the packages I need, And I believe my webpack is setup correctly. I can run the server and the dev script with no errors at all. If I was to put anything in the HTML(e.g. text) file, it shows. But no react components on it. Webpack.config const path = require("path"); const webpack = require("webpack"); module.exports = { entry: "./src/index.js", output: { path: path.resolve(__dirname, "./static/frontend"), filename: "[name].js", }, module: { rules: [ { test: /\.js$/, exclude: /node_modules/, use: { loader: "babel-loader", }, }, ], }, optimization: { minimize: true, }, plugins: [ new webpack.DefinePlugin({ "process.env": { NODE_ENV: JSON.stringify("development"), }, }), ], }; HTML <body> {% load static %} <div id="main"> <div id="app"> </div> </div> <script src="{% static 'frontend/main.js' %}"></script> </body> React import React, { Component } from "react"; import ReactDOM from 'react-dom'; export default class App extends Component(){ constructor(props){ super(props); } render(){ return <h1> Site Placeholder </h1> } } ReactDOM.render(<App />, document.getElementById('app')); The index.js just has an import: import App from "./components/App"; Views simply renders the index.html def index(request, *args, **kwargs): return render(request, 'frontend/index.html') I am not getting any errors anywhere, but my html is blank.

Django and HTML Dropdown : Populate Parent / Child field with Selected any one of the Child Attributes
I have 3 models which are being used for Dropdown, and user can select value from any of dropdown. When user select the parent the child dropdown auto-filters (this is working), however need a functionality where, when a user select a child, parent dropdown will also get filter. While doing research I came across with such functionality on site "https://www.hertzcarsales.com/nashville.htm?utm_source=google&utm_medium=organic&utm_campaign=GoogleLocalListing". Due to security reason cannot share actual models. however can refer to the site. User can select Vehicle Make, and the model + Body Style will auto filter, and when user selects just Body Style, then Make & Model will be filtered accordingly. For example, in below screenshot I just selected Body Style as Truck, and all Make & Model are auto-filtered. Please suggest or point me how this can be doable, just a pointer or small suggestion would help. I did tried using JavaScript, but unable to do reverse dropdown filter. -

How to use a request.session stored value within a DetailView as the initial data to a ModelForm input field?
I'm a beginner at Django and I'm currently developing my first project. I'm using DetailView to display information from an object and in this same template there's a button that redirects to a ModelForm template. I've already gotten how to prepopulate the user field with form.save(commit=False) and a date field by simply setting a default on models. But I'm having trouble setting a ForeignKey field up. I've already tried different methods and variations of them but none worked. The one below is the last one I've tried. I've already studied and tried to make it work but I'm not sure how to use django sessions to pass the '''Book.id''' or anything that could possibly replace it from the DetailView to the ModelForm field. There were times I've gotten an error saying certain object was not JSON serializable then I've tried to make it work importing serializing modules and it didn't work as well. I also have doubts if I'm using the best method to achieve what I want using the DetailView class. Obs.: the input field is there with the options to pick. My intention is to set the initial value with previous page object. views.py class BookView(DetailView): model = … -

How to setup django-sslserver with openssl?
I have installed OpenSSL64 successfully on my windows machine. I have a django project that I want to use SSL on. I've found github repo called "django-sslserver". I've set it up. The issue I am having is, when launching the django project through this command ($ python manage.py runsslserver myipaddress:portnumber), the https doesn't work and the browser shows that a certificate while it does exist, it is however not secure and its given by "localhost". So I figured I just need to get the proper certificate. My question is, how do I create the proper crt and key through openssl? I need to execute this command ; $ python manage.py runsslserver --certificate /path/to/certificate.crt --key /path/to/key.key -
Django filter object by ManyToMany and only return those ManyToMany relationships that match

How do I filter those many to many relationships also to return the Group where Users have that category and ONLY those Users within the Group? -

Django + Vue deployment pythonanywhere.com
I am new to vue and cannot figure out how to get my Django/Vue app deployed on pythonanywhere.com. For the backend I am using cookiecutter which I have deployed as normal using [this guide][1] . This is working and I can view the API endpoints. I have been having difficulty connecting up the vue part, this is probably due to being new to JS frameworks so I am not entirely sure how they run in production. From [this post][2] I know I need to serve my Vue files as static files but I dont know how to do this. I have tried to build my vue project on my local machine which creates a dist folder, I added the contents of this folder to my django static folder and ran collectstatic command but this has not worked for me. Does anyone have experience with Vue and Django on pythonanywhere that could point me in the right direction? Any ideas of how to get this working? Thanks, John -
