disable post button after clicked [duplicate]
(new to js) I am having an issue where the user can click the submit button multiple times and the post gets posted multiple times. To fix this I found this JavaScript that is supposed to disable the post button after it is clicked. However when the button is click the post request is not sent and nothing happens. How can I still submit the form but disable the button after the click <form method="post" enctype="multipart/form-data" id="PostForm" data-models-url="{% url 'ajax' %}" novalidate> <!--id="modelForm"--> {% csrf_token %} <fieldset class="django-ckeditor-widget"> <legend class="border-bottom mb-4">New Car</legend> {{ postForm.stuff}} ..... </fieldset> <div class="form-group"> <button id="submit-btn" class="action-btn" type="submit">Post</button> </div> </form> <script type="text/javascript"> document.getElementById("PostForm").addEventListener("submit", function (event) { event.preventDefault(); }); </script> -

Filter data of a JavaScript chart by date range - Django Project
I want to create a Javascript chart with a date selector in my Django project like this example: https://plotlydash.com/pie-chart-with-drop-down-list-and-date-picker-range-in-plotly-dash/ I've already created a date selector input in my chart.html file, which allows me to append the input date value to URL when I click "generate report". (For example: it will append: ?start=2022-02-02&end=2022-02-24). I was also able to call these two dates by {{request.GET.start}} and {{request.GET.start}} in my HTML. My chart data is based on a list of dictionaries, which is defined in views.py: I count the number of records with Mike, Jane and Jack. mylist= [{'Date': '2021-10-02', 'ID': 11773, 'Receiver': Mike}, {'Date': '2021-10-02', 'ID': 15673, 'Receiver': Jane}, {'Date': '2021-10-03', 'ID': 11773, 'Receiver': Mike}, ... {'Date': '2021-12-25', 'ID': 34653, 'Receiver': Jack}] mike=len(tuple(d for d in mylist if d['Receiver'] == 'Mike')) jane=len(tuple(d for d in mylist if d['Receiver'] == 'Jane')) jack=len(tuple(d for d in mylist if d['Receiver'] == 'Jack')) count = [mike, jane, jack] My JavaScript chart: <!-- pie Chart --> <div class="col-xl-4 col-lg-4"> <div class="card shadow mb-4"> <div class="card-header py-3 d-flex flex-row align-items-center justify-content-between"> <h6 class="m-0 font-weight-bold">Team Chart ({{request.GET.start}} - {{request.GET.end}} )</h6> </div> <!-- Card Body --> <div class="card-body"> <div class="chart-area"> <canvas id="myPieChart"></canvas> <script> var ctx = document.getElementById("myPieChart"); var startDate = … -

prevent multiple form submissions
I have been looking for a way to prevent users from clicking the submit button on a form multiple times resulting in the post being submitted multiple times. Most of the post I found on stack were at least 5 years old and they all offered different ways to solve the issue, there didn't appear to be a best practice method on how to remedy this issue. I took a quick look in the docs to see if they have added anything but I didn't see anything. In 2021 what is the best practice to prevent multiple form submissions. -
Expected view Equation1View to be called with a URL keyword argument named "pk"
I'm trying to get data directly from request body in json. Making calculations in API will be main part of my Django REST Api. In the future I'm going to add database from which I'll be getting some data that will be used in calculations. I'm having a problem with error AssertionError: Expected view Equation1View to be called with a URL keyword argument named "pk". Fix your URL conf, or set the 'lookup_field' attribute on the view correctly. I don't know where should I put the pk parameter. Using the api below I should be able to send {"name":"xxx", value:1.23} in request body and get {"emission":1.23} in json response. Ofcourse it will be more complicated in future as getting more data from request body and connecting it with data from db but now I have to make it simple. api urls.py: from .views import Equation1View from django.urls import path urlpatterns = [ path('equation/1', Equation1View.as_view()) #path('equation/2'), #path('equation/3'), ] views.py from aiohttp import request from rest_framework import generics from .serializers import EmissionSerializer, EquaSerializer # Create your views here. class Equation1View(generics.RetrieveAPIView): queryset = '' serializer_class = EquaSerializer(context={'request':request}) serializers.py from rest_framework import serializers class EquaSerializer(serializers.Serializer): emission = serializers.SerializerMethodField('perform_equation') def perform_equation(self): request = self.context.get("request") if … -

How to apply timezones to Django Model DateTimeFields
When a Django model contains a DateTimeField the date is always saved in UTC timezone. If you add a date that had a time zone the information is translated and will be retrieved differently. This happens even if the TIME_ZONE has been set in settings.py and the date was created using timezone.localtime(timezone.now()). The same issue happens when the date is added dynamically, like with models.DateTimeField(auto_now_add=True) or models.DateTimeField(auto_now=True). How can I retrieve or save date times in the correct timezone? -
