How can I access Django model fields in form via JavaScript to auto calculate fa ield?
I would like to auto-calculate my deposit amount height in a form. Therefore, I included JavaScript to make it happen. The idea: After entering the net into the form, the suitable deposit height will be displayed in the amount field. And there is nothing to do for the user here. I really appreciate any suggestions since I am total beginner with Django. I tried to access the field via known methods like netObj.fishing_type and ['fishing_type'] but I feel like this is not the issue. Somehow I can't access the model fields of the triggered record. html file {% extends 'base.html' %} {% load crispy_forms_tags %} {% block content%} <p> </p> <div class ="form-group"> <form method="POST" action="{% url 'put_deposit' %}" enctype="multipart/form-data"> {% csrf_token %} {{form|crispy}} <script> // Get the input elements by targeting their id: const net_input = document.getElementById('id_net'); const vessel_input = document.getElementById('id_vessel'); const amount = document.getElementById('id_amount'); // Create variables for what the user inputs, and the output: let netObj = 0; let vesselObj = 0; let height = 0; // Add an event listener to 'listen' to what the user types into the inputs: net_input.addEventListener('input', e => { netObj = e.target.value; console.log(netObj); updateAmount() }); // Update the value of net … -

Django Ordering by a specific ManyToMany Field
the following structure is given: `python class MovieTranslation: lang=CharField() title=CharField() class Movie: key = CharField() movie_translations = ManyToManyField(MovieTranslation) ` Now for example, for english users I want to sort by the english MovieTranslation of a Movie? I want to use it in a ViewSet as a Filterset class. I think it should be something like order_by(movie_translations__name='en'__title). The last part of course doesn't work. I found solutions, for filtering before, but I do not think filtering for english Translations work, since then I get a list of Movie Objects who have an english Title, but could still have other languages. I want to sort specifically by the field of a manytomany field. So is there a way to order by a specific ManyToMany Instance (i.e. all MovieTranslations where the name is 'en' ) ? I was thinking about annotate, but had the same problems I am thinking now that maybe joining with a specific ManyToMany field could work. -

How to restrict AuthenticateCallbackView in django-microsoft-auth only to registered accounts?
I am using django-microsoft-auth in my Django project. I am trying to restrict this option only to registered users so only people who have already registered themselves are allowed to use Log in with Microsoft button.

In case someone doesn't have an account it would send a message: Please register your account first. -
