Question

我正在尝试在Django中构建一个搜索表单，但不幸的是我无法让代码工作，就像教科书所说的那样（我使用的是Django Book）。我无法提交表单，所以我添加了一个按钮，修复了该按钮。不幸的是，现在我无法在视图中获取表单来执行搜索功能。它只是给我一个404错误。

下面，请找到模板，

<html>
  <head>
    <title>Search</title>
  </head>
  <body>
    <form action=“/search/“ method = “get”>
        <input type = “text” name = “q”>
       < button type = “submit”> Submit</button>
    </form>
  </body>
</html>

请原谅缺少括号。我无法弄清楚如何让网站不将其解释为HTML。

视图，

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def search_form(request):
    return render(request, "search_form.html")
def search(request):
    if 'q' in request.GET:
        message = "You searched for: %r" % request.GET['q']
    else:
        message = "You submitted an empty form."
    return HttpResponse(message)

URLconf，来自django.conf.urls import include，url 来自django.contrib import admin 来自mysite2.views import hello，current_datetime，hours_ahead 来自图书导入视图

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^hello/$', hello),
    url(r'^time/$', current_datetime),
    url(r'^time/plus/(\d{1,2})/$', hours_ahead),
    url(r'^search-form/$', views.search_form),
    url(r'^search/$', views.search),
 ]

和错误页面。

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/search-form/%E2%80%9C/search/%E2%80%9C?%E2%80%9Cq%E2%80%9D=A+Really+Good+Book
Using the URLconf defined in mysite2.urls, Django tried these URL patterns, in this order:
^admin/
^hello/$
^time/$
^time/plus/(\d{1,2})/$
^search-form/$
^search/$
The current path, search-form/“/search/“, didn't match any of these.

您的表单属性应使用直引号"，而不是引号“或”。

<form action="/search/" method="get">
    <input type = "text" name = "q">

您的错误消息search-form/“/search/“表明您的代码确实包含“，这不仅仅是Stack Overflow问题中的问题。
