python - Django 网址无法重定向到单个网址

Question

我在“products”应用程序中的所有 url 都重定向到 products_list

urls.py
from django.conf.urls import url
from .views import(
        product_list,
        search,
        add_product,
        category_single,
        manage_product_image,
        edit_product,
        download_product,
        single,

        )

app_name = 'products'

urlpatterns = [
    url(r'^', product_list, name='product-list'),
    url(r'^search/',search, name="search"),
    url(r'^add/',add_product,name='add_product'),
    url(r'^category/(?P<slug>.*)/$',category_single,name="category"),
    url(r'^(?P<slug>.*)/images/',manage_product_image,name="manage_product_image"),
    url(r'^(?P<slug>.*)/edit/',edit_product,name="edit_product"),
    url(r'^(?P<slug>.*)/download/(?P<filename>.*)$',download_product,name="download_product"),
    url(r'^(?P<slug>.*)/$',single,name="single_product"),
]

如果我输入 http://localhost:8000/products 它会将我发送到完美的产品列表，但是输入 http://localhost:8000/products/add/ 还向我发送了不完善的产品列表，应该是添加产品的表格。 View .py

def add_product(request):
    form = ProductForm(request.POST or None)
    if form.is_valid():
        product = form.save(commit=False)
        product.user =  request.user
        product.slug = slugify(form.cleaned_data['title'])
        product.active = False
        product.save()
        return HttpResponseRedirect('/products/%s'%(product.slug))
    context = {
        'form':form,
    }
    return render(request,"products/edit.html",context)

我已经尝试注释 view.py 中的所有代码行，只是为了呈现模板仍然没有通过，只是带来了产品列表。

你的第一个url(..) [Django-doc] pattern 是匹配所有内容的模式。事实上，正则表达式 ^ 匹配所有字符串，因为您只指定字符串开始 anchor 。

您还应该添加一个字符串结尾 anchor ($):

urlpatterns = [
    url(<b>r'^$'</b>, product_list, name='product-list'),
    # ...
]
