Security: bypassing login with URL entry
I’m looking to create a login system for my Django web application with is connected to a MySQL database with a table for managers that holds their name, email, and password. My login screen has a URL of localhost/login. I want to query the off-server database for the username and password for each manager that was entered when the user puts in the information. If the credentials match, then I want to redirect them to the manager page, which is localhost/manager. If they don’t match, then I want to keep them at that page, localhost/login. My question is what’s stopping the user from inputting the localhost/manager URL path into their browser and bypassing the login, getting access without getting authenticated? Is there a good way to store the user name and password in the database to make them more secure but also accessible and checkable again? -

Display thumbnail from image without creating or modifying file, based off of url?
I have a database with rows, with one of the fields being image_url. The images specified by these urls are high resolution and have different aspect ratios. I need to use some of these images to display thumbnails. I am thinking of running them through an image program to automatically create thumbnails, and then add a new image_thumbnail_url field of the like. Alternatively, I have seen some software which leads me to believe it may be possible for django to take these images, resize them in memory and then serve them to the client, without having to create new resize images. Is such a method possible, and if it is possible, is it efficient, or frowned upon? -
How to have a local instance or React hit a local instance of Django
I have a django api (djangorestframekwork, django2.1, python 3.6) that I run locally - http://127.0.0.1:8000/api/cards/b361d7e2-6873-4890-8f87-702d9c89c5ad. This api seems to work well. I can hit it via the web api or use curl/requests to add to or view the database. Now, I want to be able to have my React project hit this api. I can have my react project hit a different api and it returns the data, but when I replace that URI with my own URI it breaks. App.js - there is one line commented out. Switch that out with the other to switch between the public and private api. import React from 'react' import keyforge from '../api/keyforge' import localhost from '../api/localhost' import SearchBar from './SearchBar' class App extends React.Component { onSearchSubmit = async (term) => { const response = await localhost.get("api/cards/" + term) //const response = await keyforge.get("api/decks/" + term) console.log(response) } render () { return (<div className='ui container'> <SearchBar onSubmit={this.onSearchSubmit} /> </div>) } } export default App keyforge.js - this one works! import axios from 'axios' const proxyurl = 'https://cors-anywhere.herokuapp.com/' const url = 'https://www.keyforgegame.com/' export default axios.create({ // baseURL: 'https://www.keyforgegame.com/api/decks/' baseURL: proxyurl + url }) localhost.js - this one does not work import axios from 'axios' … -
Accessing dictionaries given django template's attributes?
So my problem is that I need to iterate over a dictionary given an attribute, which is the value of the for loop. For example, I have a dictionary called my_dictionary which is being iterated by a for loop in a django template, with an attribute called q. What I need is to access to that dictionary by using the q attribute. I tried with {{my_dictionary.q}}, {{my_dictionary.{{q}} }} but none of them did work. What can I do? I guess it should be similar as in Python my_dictionary[q]. Thank you. -
User Profile 'Syntax Erro'r in Django
I am trying to create the user profile in Django. t is a new User model that inherits from AbstractUser. It requires special care and to update some references through the settings.py. Ideally, it should be done at the beginning of the project, since it will dramatically impact the database schema. Extra care while implementing it.

What are dependancies and why should I care about them?
I am a beginner to web development, and am currently engaged in creating a Django web application to interface with a MySQL database. Through the time I've spent reading the documentation for Django, it constantly talks about isolating dependancies using virtual environments like virtualenv. I don't really understand what a dependency is and why creating a virtual environment would help 'isolate' them from each other. What is a virtual environment? Is it like another machine running on your machine? Any input for these conceptual questions would be much appreciated. -
WHY connect MySQL database to Django?
I am creating my first ever Django web application, which is essentially a portal for managers to view the current status of a MySQL database. I’m having trouble understanding why I should connect MySQL to Django instead of just writing Python scripts to connect directly to the database using the pymysql library. Plus, if I decide to go forward with connecting Django and MySQL, what would interfacing them look like? I'm currently hosting both the Django web app and the MySQL database on my computer, but will eventually host them on external servers. I'm a webdev beginner and any input would be much appreciated. -

I'm following the tutorial to create a CHAT to learn using Channels. In this way I'm following this tutorial : https://channels.readthedocs.io/en/latest/tutorial/part_2.html I have done everything. When I apply the command: python manage.py migrate I get : Operations to perform: Apply all migrations: admin, auth, contenttypes, polls, sessions Running migrations: No migrations to apply. Whereas what is expected : Operations to perform: Apply all migrations: admin, auth, contenttypes, sessions Running migrations: Applying contenttypes.0001_initial... OK Applying auth.0001_initial... OK Applying admin.0001_initial... OK Applying admin.0002_logentry_remove_auto_add... OK Applying contenttypes.0002_remove_content_type_name...

OK And when I run my Channels server developement (ASGI), I go on the url http://127.0.0.1:8000/chat/lobby/ and I still get on my browser's Javascript console the message error : WebSocket connection to 'ws://127.0.0.1:8000/ws/chat/lobby/' failed: Error during WebSocket handshake: net::ERR_CONNECTION_RESET I don't know why it is not working.

Why can't I use Jinja syntax in Javascript for a django site?
So for those of us who use Python and Django framework to develop a website, there is this awesome tool known as jinja which can be used as a template engine. For example: Instead of hard-coding an import like this: <script src="assets/js/onebutton.js"></script> We can do this: <script src="{% static 'assets/js/onebutton.js' %}"></script> In this case, it automatically searches for a folder named static and goes inside to look for the needed code. But why isn't it possible to use jinja template in Javascript. For example: homepage.html <script src='whatever.js'></script> <p>Another example</p> <button id="clickme"> click me </button> whatever.js $(function() { $('#clickme').click(function(){ $.ajax({ headers : {'X-CSRFToken': getCookie('csrftoken')}, type: "POST", url: '{% url "func" %}', //<--Problem arise here datatype:"json", data: {}, success: function(data){ var new_template = '<h1> %firstmsg% </h1>'; var new_frontend = new_template.replace('%firstmsg%',data.message); console.log(new_frontend); document.getElementById('wor').innerHTML+=new_frontend; } }); } } Django would recognize the url in the AJAX request as /'{% url "func" %}' instead of /func The only way to solve this is to move the entire code from whatever.js into the homepage.html under <script></script> brackets. Perhaps we need to import something for Jinja templating to work?
