目标：使用django forms表单实现两个参数的求和
实现代码：
forms.py
from django import forms
class AddForm(forms.Form):
a=forms.IntegerField()
b=forms.IntegerField()
views.py
from django.shortcuts import render
from django.http import HttpResponse
from .forms import AddForm
def TestForm(request):
if request.method=='POST':
form=AddForm(request.POST)
if form.is_valid():
a=form.cleaned_data['a']
b=form.cleaned_data['b']
return HttpResponse(str(int(a)+int(b)))
else:
form=AddForm()
return render(request,'index.html',{'form':form})
index.html
<form method='post'>
{% csrf_token %}
{{form}}
<input type="submit" value="提交">
</form>
urls.py
from django.conf.urls import url
from django.contrib import admin
from tools.views import TestForm
urlpatterns =[
url(r'^admin/', admin.site.urls),
url(r'^form/',TestForm,name='testform'),
]
希望大神能指导如何分析该报错信息，并且根据报错信息到源码去找到错误处？
