在我们的Django项目中,我们经常会遇到要在视图中返回一个重定向到具体URL的响应,或者要将具体的URL地址嵌入到HTML页面中(如:a标签的href属性等)的情况。我们之前通常都会选择硬编码(写死)的方式来实现类似上述的需求,但是这并不是最优的解决办法。例如: 在视图函数中 def add_student(request):ifrequest.method =...
# "my_app1/views.py" from django.shortcuts import render from django.http import HttpResponse def index(request): return render(request, 'index.html') def test1(request): return HttpResponse("Test1") def test2(request): return HttpResponse("Test2") def test3(request): return HttpResponse(...
例如,下面是Django网站本身的URLconf节选。 它包含许多其它URLconf: fromdjango.conf.urlsimportinclude, url urlpatterns=[#... 忽略 ...re_path(r'^community/', include('django_website.aggregator.urls')), re_path(r'^contact/', include('django_website.contact.urls')),#... 忽略 ...] 路由转...

from django.core.validators import URLValidator from django.core.exceptions import ValidationError val = URLValidator() try: val('httpx://www.google.com') except (ValidationError,) as e: print(e) edit: ah yeah, this question is a duplicate of this: How can I check if a URL exists with...
In this case, the URL is a string that ensures the exact location of data, and data is just an object sent to the server. And if the request gets succeeded, the status comes through the success. There is a shorthand code demonstration for this process. Code Snippet: <!DOCTYPE html> <...
在Django中,可以通过使用模板语言和静态文件的结合来向静态URL添加JavaScript变量。具体步骤如下: 首先,在Django的模板文件中,可以使用模板语言将JavaScript变量嵌入到HTML中。例如,可以使用{{ variable_name }}的语法将变量插入到HTML标签的属性中或者直接在JavaScript代码中使用。
"admin/books/report.html", {'book_list':Book.objects.all()}, RequestContext(request,{}), ) report=staff_member_required(report) 因为我们把分组操作留给了模板,该视图非常简单。然而,有几段微妙的细节值得我们搞清楚。 我们使用了django.contrib.admin.views.decorators中的staff_member_required修饰器。该...
Changed in Django 3.0: In older versions, the keyword arguments withNonevalues are made up also for not provided named parts. If no URL pattern matches, or if an exception is raised during any point in this process, Django invokes an appropriate error-handling view. SeeError handlingbelow. ...
