How to pass a variable/value with DeleteView in django urls
is there any way to pass a variable with DeleteView in Django? This is my code: path('category/<int:pk>/delete/', DeleteView.as_view( model=Category, success_url=reverse_lazy('expenses:category-list') ), name='category-delete'), I need to pass a number of related elements in database.

Utilise AJAX & javascript to create a toast with Djangos messaging framework
I have followed a tutorial to utilise AJAX to validate an input field before attempting to submit. I have it working on my django built site; however, I have been using toasts to alert the user to other actions and did not want to get way from this. $("#id_hub_name").focusout(function (e) { e.preventDefault(); // get the hubname var hub_name = $(this).val(); // GET AJAX request $.ajax({ type: 'GET', url: "{% url 'validate_hubname' %}", data: {"hub_name": hub_name}, success: function (response) { // if not valid user, alert the user if(!response["valid"]){ alert("You cannot create a hub with same hub name"); var hubName = $("#id_hub_name"); hubName.val("") hubName.focus() } }, error: function (response) { console.log(response) } }) }) This is my current JS, I want to change the alert function to use toasts instead.

How can I write more columns than defined in header?
I am using Datatables jQuery plugin and I have the following columns in html: <tbody> <td class="test1">elem1</td> <td class="test2" style="display: none;">elem2</td> </tbody> I activate one or the other column from jQuery ( always one ). Problem is that 'datatables' plugin yells error because num of columns from tbody is not equal with num of columns from thead (1 in my case 'cause I only want one to display). Is there a workaround for defining more columns than specified in the header and pass validation ? I am writing the html thought Django's template language. For showing columns I use somthing like this: <select onchange="selectChange(this.value)"> <option>test1</option> <option>test2</option> </select> function selectChange(val) { $(`[class*="test"]`).hide(); $(`[class="${val}"]`).show(); } -
Using CheckBox in Django FilterSet
I can't seem to find any solutions to this issue.. In my models.py I have a class called Course like this: class Course(models.Model): seats_occupied = models.IntegerField(null=True, default=0) seats_available = models.IntegerField(null=True, default=25) # etc... In my filters.py I have this filter for it: class CourseFilter(django_filters.FilterSet): seats_occupied = django_filters.NumberFilter(field_name='seats_occupied', lookup_expr='lt') At this point, I need to enter a number to see if seats_occupied is less than that number. But I would like to just have a CheckBox or Possibly a multiple choice with "open/full" courses, that will only give me the courses that are not full. Is there a good way to accomplish this? -

How to serve local CSS files in my Django-Dash-Plotly app
I need to add CSS to my project to enable it to stop conflicting with Bootstrap CSS. I have the exact problem this person is having with fixed columns. The solution is to add this CSS snippet somewhere in my directory: .dash-spreadsheet .row { flex-wrap: nowrap; } My only problem is, I'm an extreme novice when it comes to styling files and I feel completely lost on where to add this snippet into my Django-Dash project. I've read the documentation from Django-Dash for local files Also looked at Dash-Plotly official documentation for adding CSS ... and I'm still confused on where to add the code snippet. For anyone wondering I've tuned my django settings.py to fit the Django-Dash requirements, according to documentation. Here is how my Django project is set-up: app.py is my Dash app that is within my home Django app. stockbuckets folder is the main project folder that holds my settings.py file. I see I am also meant to add serve_locally = True as an in app argument or global variable for DASH_PLOTLY in settings.py. Either method I use just gets my project stuck in HTTP GET... trying to find the local files I'm assuming? Would greatly appreciate … -

Django, Docker and traefik shows 404 on deploy but no error logs - using django-cookiecutter
