NoReverseMatch error when using reverse function
I am trying to redirect from one view to another and I get the following error: NoReverseMatch at /challenges/1/answer/ Reverse for 'results' with arguments '(1,'test')' not found. 1 pattern(s) tried: ['challenges\/(?P<challenge_id>[0-9]+)\/results\/$'] I have the following code in views.py: def answer(request, challenge_id): challenge = ... result = "test" return HttpResponseRedirect(reverse('challenges:results', args=(challenge.id, result))) def results(request, challenge_id, result): Here's urls.py path('<int:challenge_id>/', views.detail, name='detail'), path('<int:challenge_id>/results/',views.results, name='results'), path('<int:challenge_id>/answer/',views.answer, name='answer'), My understanding is that 'reverse' in an HttpResponseRedirect would redirect to results if I pass the 'result' in args? Thanks in advance! -
From javascript to server
I have this code which allows you to upload an image onto the canvas and mark out segments on the canvas. When the canvas is double clicked, the coordinates of the segments would be added to an array. Is it possible to write this array segmentList into a JSON file or send it to a django server? Also is there anywhere that i could read up on this? Thanks in advance. $("#imageCanvas").click(function(e) { var x = e.offsetX var y = e.offsetY // Adding 'X' and 'Y' values to the respective list xList.push(x); yList.push(y); var coods = document.getElementById("coods"); coods.innerHTML = 'X: ' + x + ' Y: ' + y; }) $('#imageCanvas').on('dblclick', function() { first = new Segmentation(); xList.pop() yList.pop() first.X = xList; first.Y = yList; segmentList.push(first); if(first.X == "" && first.Y == "") { alert("No points seleected!") } else if(first.X.length < 3 && first.Y.length < 3) { alert("Please select at least more than 3 points!") } else { for( i=0; i< first.X.length; i++) { if(i<first.X.length-1) { console.log(first.X) context.beginPath(); xpos = first.X[i]; console.log(first.X[i]) ypos = first.Y[i] var xpos1 =first.X[i+1] var ypos1 =first.Y[i+1] } if(i==first.X.length-1) { xpos = first.X[i] ypos = first.Y[i] var xpos1 =first.X[0] var ypos1 =first.Y[0] } context.moveTo(xpos, ypos) context.lineTo(xpos, … -
Making my Django Views into a DjangoRestFramework API Endpoint
I have a payment verification View which utilizes some parameters like the secret key, and some other authentication parameters. I would like to make the view into an API endpoint whereby i can just enter the parameter and the it returns the response.

Django + Tempus Dominus - Submit django form without submit button
I have a functioning datepicker on my django app called tempus dominus. I am having some trouble trying to set this datepicker to submit without having to click on a submit button.

My js skills are quite rusty so probably the problem lies somewhere there... my forms.py class MyForm(forms.Form): date_from = forms.DateField( required=True, widget=DatePicker( options={ 'minDate': '2018-01-20', 'maxDate': '2020-10-20', }, ), initial='2020-08-01', ) date_to = forms.DateField( required=True, widget=DatePicker( options={ 'minDate': '2018-01-20', 'maxDate': '2020-10-20', }, ), initial='2020-10-19', ) my template <div class="col" id="form_div"> <form method="post" action="." id="datetimepicker" class="form-inline justify-content-center"> {% csrf_token %} {{ form.as_p}} <input type="submit" id="submit" value="enviar" style="width:70px" /> </form> </div> my js file $("#datetimepicker").on("change.datetimepicker", function () { $( "#datetimepicker" ).submit(); }); Any help is appreciated! -

How many objects may I have in my database before order_by will get slower? Or this is all up to machine specs? -
