I am trying to create a form which asks user to input a value, do some
calculations on it and show the results back to the user. Here is what I've
done: I have created an app called QMarcum. Inside this app I have this
views.py, forms.py and urls.py:
views.py
from django.shortcuts import render
from scipy.integrate import quad
import scipy, numpy, math
from scipy import integrate
from django.http import HttpResponse
from .forms import Calculate
def integrand(x):
Q_y = (1/(math.sqrt(2*math.pi)))*math.exp((-x**2)/2)
return Q_y
y = Calculate.y
ans, err = quad(integrand, float(y), math.inf)
print(ans)
return render(request, 'test.html', {'form': Q_y})
forms.py
from django import forms
class Calculate(forms.Form):
y = forms.FloatField()
urls.py
from django.urls import path
from . import views
urlpatterns = [
path('form', views.integrand),
]
form.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="post">
{% csrf_token %}
{{ form }}
<button type="submit">Submit</button>
</form>
</body>
</html>
The form asks user to input a value (y) (y is printed on terminal
successfully), however, print(ans) doesn't print the value AND also I don't
know how to show the calculated result (ans) to user.
Thanks in advance
