Django Query many to many field count miscalculation

How to safely execute user-written code in the backend?
I'm trying to build a Django web application that allows users to write Python code and runs that in the backend, kinda like how an IDE would work.

Would running it inside a Docker container be a good solution? -
Django Authentication Application
I've just started to the django and got a little lost in between various doumentations and outdated tutorials. What I want to achieve is to create a simple dashboard application that also contains some backend scripts to integrate various apis most of them are open API's like weather API's , calendar API's etc just for learning. But I need to create a login page for the application and current tutorials for the authentication mosule of django is a little bit cunfusing as it never gives me how to implemelent a login form to the auth backend. I need a little bir more simple documentation for that. Is there anyone able to help me on that. I know the question is not code related but still any help will be appriceated. Most of findings from my previous searches are outdated and implementing those methods are often causes errors like non-existent templates etc... Meanwhile I'll be also checking the offical documentation. Thank you. -
Hashicorp Vault - Django query from docker container
Good afternoon, I have a two docker containers, one running a django app and the other running Hashicorp Vault as I am starting to play with Vault in a dev environment. I am using HVAC from a django view to write a secret to the vault that is entered by a user to set up an integration to a REST API for a data pull. When I run the following from my host machine, it writes just fine. client_write = hvac.Client(url='http://127.0.0.1:8200', token='MY_TOKEN') client_write.is_authenticated() When I run the same from the Django container, it fails with: requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=8200): Max retries exceeded with url: /v1/auth/token/lookup-self (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f2a21990610>: Failed to establish a new connection: [Errno 111] Connection refused')) Django docker container is running on localhost:8000 & the vault is localhost:8200. I also have a front end written in VueJS running on localhost:8080 that has no trouble communicating back and forth with the django rest API (django-rest-framework). Is there something in vault that I need to list where the queries can come from? Thank you, I am very new to Vault and am struggling through it a bit. BCBB -
Why is django's forloop.counter0 confused by an adjacent loop?
I have a template that looks like this: <table> <tbody> {% for row in rows %} <tr> {% for column in row %} <td>{{ column }}</td> {% endfor %} <td><input type=checkbox name="checkbox_{{ forloop.counter0 }}"></td> </tr> {% endfor %} </tbody> </table> The checkboxe names in the table that get generated start with checkbox_1 instead of checkbox_0. If I remove the inner for loop however: <table> <tbody> {% for row in rows %} <tr> <td>Column 1</td> <td>Column 2</td> <td><input type=checkbox name="checkbox_{{ forloop.counter0 }}"></td> </tr> {% endfor %} </tbody> </table> They start with checkbox_0 as they should. The inner loop appears to be messing up the counter for the outer loop. I even tried to use the with tag, but that didn't seem to help: <table> <tbody> {% for row in rows %} {% with forloop.counter0 as outer_counter %} <tr> {% for column in row %} <td>{{ column }}</td> {% endfor %} <td><input type=checkbox name="checkbox_{{ outer_counter }}"></td> </tr> {% endwith %} {% endfor %} </tbody> </table> Any idea what might be going wrong? -

I am trying to toggle between 2 images based on a condition. I am thinking to change the src of img tag. I am able to change the src but on the webpage the image is not getting updated. can someone point out where or what should be used or updated. Here is my JS code -> success: function(data){ if(data.status == 200){ if(data.message == "Liked"){ document.getElementById("like_image_state_change").src="{% static 'FrontEnd1/Static_Images/CovrPage_Like_R.png' %}"; } else if(data.message == 'Like Removed'){ document.getElementById("like_image_state_change").src="{% static 'FrontEnd1/Static_Images/CovrPage_Like_W.png' %}"; console.log(document.getElementById("like_image_state_change")); } } else{ console.log('wrong'); } } }); Here when I console the document.getElementById in 'like Removed' I could see the updated src for the Image but the Image is still the same on the webpage. PS -> The backend I am using is DJango. (if it matters) -
Django Python contact form saves file but doesn't send the email
I'm trying to set up a simple contact form with an optional file upload; I don't want the file to be attached to the email message, I simply want to save the file to /media. I'm using required=False in the form to not require a file. But still, some of my form validation or form processing logic is wrong; the code below works when I submit the contact form without a file and I get an email.
