I was trying to set foreign key to a specific field of a model , while doing that the following error shows.

Where does Django store generated tokens resp. token links?
I am currently programming a Django app & have now also included email verification. In doing so, I have shamelessly used Djangos' token generator and misused it for my own purposes. This worked because an email verification works very similar to a password reset: A user enters his data in a form An email is sent The user clicks on the hash link The link verifies the user's input But now I ask myself where Django stores these tokens or links? There is an expire value in the settings (PASSWORD_RESET_TIMEOUT) but as I look up the generator(PasswordResetTokenGenerator) it is just used for comparison. This leads me to the question: Where does Django store these links? Do they ever expire? What happens if I generate an account & never click the email link? -

How to use Nginx as GRIP compatible proxy
I have an API get_alerts that returns list of alerts stored in a DB collection. I need to convert that into real time API(real time in sense that whenever alert gets added to a DB collection, that new alert should be sent to open connections, there's an API for post_alert too). For that, I have two options, websockets and server sent events. I decided to go with server sent events because I didn't need full duplex communication provided by web sockets and server sent events seemed comparatively simple. Django has a external package Django EventStream. I am following this link . It requires me to use GRIP compatible server. I am using Nginx. I searched but didn't find anything on how to make Nginx a GRIP compatible proxy. Isn't any other package that does it in Django? Do real time APIs require GRIP compatible proxies in other ecosystems too like NodeJS or etc? -

How do i set attributes on a single option of a CheckboxSelectMultiple ChoiceWidget in django?
I have a django app with multiple choice questions and answers. The unanswered answers are stored as BooleanFields in a database table and rendered as a form to be answered by the user.

How to use div for background in html
Hi I am trying to build a website, and I am trying to use particles.js as my background and display the content in overlaying manner. However, it is displaying it on top of the page instead of the background. When I set its position as absolute, its changes the format of my website. How can I set that div as the background? I have my background div id set as particles-js here is my code for base.html: <!DOCTYPE html> <html lang=en> {% load static %} {% static 'style.css' %} {% static 'particles.json' %} <head> <!-- Required meta tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous"> </head> <body> {% include 'snippets/base_css.html' %} {% include 'snippets/header.html' %} <!-- Body --> <style type="text/css"> .main{ min-height: 100vh; height: 100%; } </style> <div class="main"> <div id="particles-js"></div> <script src="https://cdn.jsdelivr.net/particles.js/2.0.0/particles.min.js"></script> <script> particlesJS.load('particles-js', "{% static 'particles.json' %}", function(){ console.log('particles.json loaded...'); }); </script> {% block content %} {% endblock content %} </div> <!-- End Body --> {% include 'snippets/footer.html' %} </body> </html> this is my home.html: {% extends 'base.html' %} {% block content %} <style type="text/css"> @media (max-width: 768px) { .right-column{ margin-left: 0px; } } @media (min-width: 768px) { .right-column{ margin-left: 20px; } … -
