Question

我跟随迈克·希伯特（Mike Hibbert）的啧啧之后，试图修改它以满足我的需要，但它不起作用。我想用自己的方式因为我的方式打破了DRY规则，我不得不为我的每个视图编写搜索逻辑我认为它可能是我的js的顺序但是我不认为它是。我可能是错的，因为我对prgramming相当新。我不确定，但我认为问题可能出在我的导航中，我在导航中导航。继承我的代码

views.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nav.html

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),
]

我看到网络中没有错误，我已经从GET切换到POST，只是试图调整一些东西以使其工作但没有任何改变。我的jquery来自CDN，但我不认为这是一个问题，但我是一个新手，可能是错的。任何有关这方面的帮助将不胜感激

Answer 1

将您的search网址定义移至urlpatterns列表的顶部，这样就不会被post_detail通配符屏蔽：

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按顺序遍历每个URL模式，并在第一个匹配请求的URL的位置停止。

您的post_detail正则表达式肯定与search/匹配。

Answer 2

我认为您可能需要在搜索网址字符串末尾添加$。

url(r'^search/$', search_title),

这让django知道它是字符串的结尾。除非你已经确认你实际上已经能够发送到search_title视图。

Ajax搜索功能在django App中不起作用
