我正在关注 Mike hibbert 的 tut 并尝试对其进行一些修改以满足我的需要，但它不起作用。我想用他的方式因为我的方式打破了 DRY 规则，我不得不为我的每个 View 编写搜索逻辑我认为这可能是我的 js 的顺序但我不认为它是。我可能是错的，因为我对编程还很陌生。我不确定，但我认为问题可能出在我的搜索在我在包含的导航中的导航上。这是我的代码
View .py
def search_title(request):
if request.method == "POST":
search_text = request.POST['search_text']
else:
search_text = ''
posts = Post.objects.filter(
Q(title__contains=search_text)|
Q(content__contains=search_text)
)
context = {
"posts": posts
}
return render(request, "posts/ajax_search.html", context)

我的帖子/urls.py
urlpatterns = [
url(r'^$', post_list, name='list'),
url(r'^tag/(?P<slug>[\w-]+)/$', tag_list, name="tag_list"),
url(r'^create/$', post_create, name='create'),
url(r'^sewp$', sewp, name='sewp'),
url(r'^(?P<slug>[\w-]+)/$', post_detail, name='detail'),
url(r'^(?P<slug>[\w-]+)/edit/$', post_update, name='update'),
url(r'^(?P<id>\d+)/delete/$', post_delete, name='delete'),
url(r'^search/', search_title),
]
我没有看到网络中有任何错误，我已经从 GET 和 POST 来回切换，只是试图调整一些东西让它工作，但没有任何改变。我的 jquery 来自 CDN，但我认为这不是问题，但我是新手，可能是错的。对此的任何帮助将不胜感激
最佳答案
将您的 search url 定义移动到 urlpatterns 列表的顶部，这样它就不会被 post_detail 通配符掩盖:
urlpatterns = [
url(r'^$', post_list, name='list'),
url(r'^search/', search_title),
url(r'^tag/(?P<slug>[\w-]+)/$', tag_list, name="tag_list"),
url(r'^create/$', post_create, name='create'),
url(r'^sewp$', sewp, name='sewp'),
url(r'^(?P<slug>[\w-]+)/$', post_detail, name='detail'),
url(r'^(?P<slug>[\w-]+)/edit/$', post_update, name='update'),
url(r'^(?P<id>\d+)/delete/$', post_delete, name='delete'),
]
来自docs :
Django runs through each URL pattern, in order, and stops at the first one that matches the requested URL.
并且您的 post_detail 正则表达式肯定匹配 search/。
