Django For Loop with Javascript Math
I am trying to figure out how to run all my for loop values through this javascript math. For example, the individual value is a loop for all my inputs whereas the total value is fixed. Exp: Indivdual values are [10, 5, 20] and the total value is 100, I want the javascript to return 10/100, 5/100, and 20/100 to get pct's for each input. This is intended to fill out a table, so it should fill in each % in a table, for instance, the row "cookies" has 10% of total, the row "fish" has 5%, and the row "soup" has 20% of the total 100. Thanks. let securities_in_asset = document.getElementById("asset-size").innerText; securities_in_asset = parseInt(securities_in_asset) for(let i = 0; i < securities_in_asset; i++) { let PctOfPool = document.querySelectorAll(`[id^="pct-of-pool"]`)[i] let indiviudal_value = document.getElementById("individual-market value").innerText; let total_value = document.getElementById("total-market-value").innerText; let problemTypeChoice = 0; if (problemTypeChoice === 0) { PctOfPool.innerText = `${((parseInt(indiviudal_value) / parseInt(total_value)) * 100).toFixed(2)}%` } else { PctOfPool.innerText = 0 } } -

Trouble getting a Django Form to render
Wondered if someone could help me with what I am doing wrong. I wish to present an order form in Django where a customer will only ever fill in an order, they will never need to retrieve an existing order. So I think I only need a POST method and no GET method. When I try to render a url with a form, I get a 405 response. In my views.py file where I think I am making a mistake I have: class RequestReport(View): def post(self, request, *args, **kwargs): form = CustomerOrderForm(data=request.POST) if form.is_valid(): form.save() return render( "order.html", { "form": CustomerOrderForm() } ) And in my app urls file I have: urlpatterns = [ path('', views.RequestHome.as_view(), name='home'), path('order', views.RequestReport.as_view(), name='order'), path('blog', views.RequestBlog.as_view(), name='blog'), path('<slug:slug>/', views.PostDetail.as_view(), name='post-detail'), ] And finally in my order.html file I have: <form action="" method="post"> {% csrf_token %} {{ form.as_p }} <input type="submit" value="Submit" class="report-buttons"> </form> I know that the Customer Order Form is fine because if I insert this in my view it renders correctly class RequestReport(CreateView): form_class = CustomerOrderForm template_name = 'order.html' success_url = "about" but I want to be able to post the form.

The timezone application in django is not working even when I have it configured in the settings
The TIME_ZONE of my application in django is currently not working I have been reading about it and what I currently have in the settings of my application corresponds to what is in the django documentation, the configurations are the following: TIME_ZONE = 'Europe/Paris' USE_I18N = True USE_L10N = True USE_TZ = True Now when I try to use timezone.now() , imported from django.utils import timezone , I get this in the following code The output is this As you can see, the timezone.now() brings me a completely different time than it should be, and I test that with date_now . I don't understand why if I'm using TIME_ZONE = 'Europe/Paris' in the application settings it doesn't bring me the exact time of the city. On the other hand a possible solution would be to use this But if I use this I would have to change in all parts of my application to put timezone.localtime(timezone.now()) when according to the documentation just using timezone.now() should work -
