一、Base views View class django.views.generic.base.View 主要的基于类的基本视图。所有其他基于类的视图都从这个基类继承而来。它不是一个通用的视图,因此也可以从django.views中导入 方法流程图 dispatch() http_method_not_allowed() options() 示例(views.py) 1 2 3 4 5 from django.http import ...
login(request, user) # django执行用户登录 return render(request, "index.html") else: return render(request, "login.html", {'msg': "用户名或密码错误"}) 函数模式写views - 需要手动判断方法,有点麻烦# users/views_old.py def user_login(request): if request.method == "POST": user_name =...
Django 的 CBV 还支持混入(Mixins),它是实现代码复用的另一种方式。混入是一种将功能模块化并复用的方法,可以将一个或多个功能分散到不同的类中。 # views.py from django.http import HttpResponse from django.views import View class CommonMixin: def common_method(self): return 'This is a common me...
In most projects, however, there comes a moment when the generic views no longer suffice. Indeed, the most common question asked by new Django developers is how to make generic views handle a wider array of situations. This is one of the reasons generic views were redesigned for the 1.3 ...
Simple usage in your URLconf您的URLconf中的简单使用 使用通用视图的最简单方法是直接在URLconf中创建它们。 如果您只是在基于类的视图中更改几个简单属性,则可以简单地将它们传递给as_view()方法调用本身: from django.conf.urls import url from django.views.generic import TemplateView ...
from django.http import HttpResponse from django.views import View class MyView(View): def get(self, request): # <view logic> return HttpResponse('result') 1. 2. 3. 4. 5. 6. 7. 因为Django的URL解析器希望将请求和关联的参数发送到可调用函数,而不是类,基于类的视图具有一个as_view()类...
Django’s generic views are built off of those base views, and were developed as a shortcut for common usage patterns such as displaying the details of an object. They take certain common idioms and patterns found in view development and abstract them so that you can quickly write common vie...
从django.views 引入了一个父类 View; 建立一个子类 Example,它继承了父类 View的全部方法; 我们另外定义了两种子类的方法get 和 post,具体方法省略。 你是否清楚了一点呢? 三、简化 URLconf 文章的最后,介绍一个小 tip,是 class-based views 极为简单的应用。

from django.views.generic.edit import CreateView class SSHAuthListView(ListView): template_name = 'app_name/sshauth_list.html' model = SSHAuth 说明: 上面我没有给出filed的值,默认就是SSHAuth这个model中的所有filed都将被展示。 其实template_name也可以不特别给出。如果你在Django设置settings.py中的TE...
