当前路径 product/ 与这些路径中的任何一个都不匹配

Question

我在连接到网址代码时遇到问题。

一切都显示良好，但是在我尝试创建之后，弹出了此错误消息。

另外，我想知道路径函数是否适用于 django 1.x。

"错误消息">

Page not found (404)
Request Method: POST
Request URL:    http://127.0.0.1:8000/product/
Using the URLconf defined in seany.urls, Django tried these URL patterns, in this order:
^admin/
^$
^register/$
^login/$
^product/create/
The current path, product/, didn't match any of these.

"url.py">

from django.conf.urls import url
from django.contrib import admin
from seany_user.views import index, registerview, loginview
from seany_product.views import productlist, productcreate
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^$', index),
url(r'^register/$', registerview.as_view()),
url(r'^login/$', loginview.as_view()),
url(r'^product/create/', productcreate.as_view())
]

"form.py">

from django import forms
from seany_product.models import seanyproduct
class registerform(forms.Form):
name = forms.CharField(
error_messages={
'required': 'enter your goddamn product'
},
max_length=64, label='product'
)
price = forms.IntegerField(
error_messages={
'required': 'enter your goddamn price'
}, label='price'
)
description = forms.CharField(
error_messages={
'required': 'enter your goddamn description'
}, label='description'
)
stock = forms.IntegerField(
error_messages={
'required': 'enter your goddamn stock'
}, label='stock'
)
def clean(self):
cleaned_data = super().clean()
name = cleaned_data.get('name')
price = cleaned_data.get('price')
description = cleaned_data.get('description')
stock = cleaned_data.get('stock')
if name and price and description and stock:
seany_product = product(
name=name,
price=price,
description=description,
stock=stock
) 
seany_product.save()

"views.py">

class productlist(ListView):

class productcreate(FormView):

Answer 1

在最后一段代码中，您尝试定向到/product/url，

class productcreate(FormView):
template_name = 'register_product.html'
form_class = registerform
success_url = '/product/' # <--- this

但是在 urls.pyurlpatterns中，您没有定义任何URL/product。请注意，/product/create与/product/不同，这就是为什么 Django 找不到任何响应 url/product并返回 404 错误的原因。

要解决此问题，请在urlpatterns中添加一个网址，例如 -url(r'^product/$', productlist.as_view())，或根据需要的任何其他视图;您还必须创建此视图。

基本上，Django 不知道/producturl 显示哪个页面。你必须定义它。
