Question

我想允许用户在数据库中搜索该主题。并在网址中显示主题名称。我已经在数据库中创建了子弹字段，但是当我尝试从数据库中获取数据时，URL无法正确显示。

网址显示：

http://127.0.0.1:8000/topic/<slug:topicname>/

我要显示的内容：

http://127.0.0.1:8000/topic/introduction-to-python/

我的urls.py文件

从django.urls导入路径来自。导入视图

urlpatterns = [
    path('', views.apphome),
    path('topic/<slug:topicname>/', views.searchtopic, name = 'searchtopic'),

]

我的项目模型

class blogposts(models.Model):
    topic = models.CharField(max_length = 200)
    slug = models.SlugField(max_length = 150, null=True, blank = True)
    post = models.TextField(max_length = 500)

    def __str__(self):
        return self.topic

这是我的观点

def searchtopic(request,topicname):
    if request.method == 'POST':
        topicname = request.POST.get('searchtopicname')

        mypost = mypostlist.objects.filter(slug = topicname)        
        context = {
            'mypost':mypost,
            }
        return render(request, 'blog/result.html',context)

我搜索主题的表格

<form action="topic/<slug:topicname>/" method="POST">
       {% csrf_token %}
       <input type="search" placeholder="Search topics or keywords" name="searchtopicname">
       <button type="submit">Search</button>
</form>

您可以使用安装了“ POST”的“ GET”方法将表单替换为：

<form action="{%url 'searchtopic' %}" method="GET">
   {% csrf_token %}
   <input type="search" placeholder="Search topics or keywords" name="searchtopicname">
   <button type="submit">Search</button>
</form>

替换urls.py：

urlpatterns = [
path('', views.apphome),
path('topic/', views.searchtopic, name = 'searchtopic'),
]

替换视图：

def searchtopic(request):
if request.method == 'GET':
    topicname = request.GET['searchtopicname']

    mypost = mypostlist.objects.filter(slug = topicname)        
    context = {
        'mypost':mypost,
        }
    return render(request, 'blog/result.html',context)
