Django表单

1、优点

2、创建一个tools APP 记得在setting.py中注册

3、在tools文件中新建一个forms.py文件

from django import forms

class AddForm(forms.Form):
a = forms.IntegerField()
b = forms.IntegerField()

4、在views.py中书写index函数

# 引入我们创建的表单类
from .forms import AddFrom

def index(request):
if request.method == 'POST':#当提交表单时
form = AddFrom(request.POST)
if form.is_valid(): # 如果提交的数据合法
a = form.cleaned_data['a']
b = form.cleaned_data['b']
return HttpResponse(str(int(a) + int(b)))
else: #当正常访问的时候
form = AddFrom()
return render(request, 'index.html',{'form': form})

5、修改index.html

<form method='post'>
{% csrf_token %}
{{ form }} <!-- 这个是 CSRF 认证，如果是 POST 方法就必须有 -->
<input type="submit" value="提交">
</form>

6、在对应的urls.py中添加记录

from django.conf.urls import url
from django.contrib import admin
from tools import views as tools_views

urlpatterns = [
url(r'^$', tools_views.index, name='home'),
url(r'^admin/', admin.site.urls),
]
