Question

我是Django的新手。我很难完成此申请。总的来说，我正在尝试一种接受两个不同数字的表格，然后将这些数字加在一起。到目前为止，这就是我所拥有的，但是我知道某处一定有错误。另外，我不知道我需要确切返回什么。任何帮助将不胜感激。

此外，最好在新页面上显示输出。我想我可以通过添加另一个HTML文件来完成此操作。但是，请您提供如何完成此操作。

forms.py：

from django import forms


class InputForm(forms.Form):
     x = forms.IntegerField(label='Enter first number: ')
     y = forms.IntegerField(label='Enter second number: ')

views.py：

from django.shortcuts import render
from django.http import HttpResponse
from .forms import InputForm

def add(request):
    form = InputForm(request.POST or None)
    if request.method == 'POST':
        form = InputForm(request.POST or None)
        if form.is_valid():
            cd = form.cleaned_data
            input1 = cd['x']
            input2 = cd['y']
            output = input1 + input2
            return ???
    else:
        form = InputForm()
        return render(request, 'addition/home.html')

urls.py：

 from django.urls import path
 from . import views

 urlpatterns = [
     path('', views.add, name='addition-home'),
 ]

home.html：

 <!DOCTYPE html>
 <html lang="en" dir="ltr">
   <head>
     <meta charset="utf-8">
     <title>Home</title>
   </head>
   <body>
     <form class="addform" method="post">
       {% csrf_token %}
       <input type="number" name="firstnumber" label="Enter first number: ">
       <input type="number" name="secondnumber" label="Enter second number: ">
       <button type="submit" name="sumbit">Submit</button>
     </form>

   </body>
 </html>

也许可以在这里尝试

views.py

def add(request):
    context = []
    form = InputForm(request.POST or None)
    if request.method == 'POST':
        form = InputForm(request.POST or None)
        if form.is_valid():
            cd = form.cleaned_data
            input1 = cd['x']
            input2 = cd['y']
            print(output)
            # You should see the number in your terminal
            context['output'] = output
            # remove return
    else:
        form = InputForm()

return render(request, 'addition/home.html', context)

template.html

{{ output }}

Django加两个数字
