| ryan | technology | `View` is the ancestor of ALL Django CBV. From the great site [Classy Class Based Views](http://ccbv.co.uk), they are described as > > Intentionally simple parent class for all views. Only implements dispatch- > by-method and simple sanity checking. This is no joke. The `View` class has almost nothing to it, but it’s a solid foundation for everything else that will be done. Its implementation has just one attribute `http_method_names` which is a list that allows you to specify what http verbs are allowed. Other than that, there’s really not much to it. You just write a simple method, something like this: def get(self, _): return HttpResponse('My Content') All that gets returned to the page is a simple HTML. You can specify the `content_type` if you just want to return JSON or plain text but defining the content_type like this: def get(self, _): return HttpResponse('My Content', content_type='text plain') You can also make the text that is displayed be based on a variable defined in the class. First, you need to define the variable content = 'This is a {View} template and is not used for much of anything but ' 'allowing extensions of it for other Views' And then you can do something like this: def get(self, _): return HttpResponse(self.content, content_type='text/plain') Also, as mentioned above you can specify the allowable methods via the attribute `http_method_names`. The following HTTP methods are allowed: * get * post * put * patch * delete * head * options * trace By default all are allowed. If we put all of the pieces together we can see that a really simple `View` CBV would look something like this: class myView(View): content = 'This is a {View} template and is not used for much of anything but ' 'allowing extensions of it for other Views' http_method_names = ['get'] def get(self, _): return HttpResponse(self.content, content_type='text/plain') This `View` will return `content` to the page rendered as plain text. This CBV is also limited to only allowing `get` requests. Here’s what it looks like in the browser:  ## Conclusion `View` doesn’t do much, but it’s the case for everything else, so understanding it is going to be important. | 2019-10-27 | cbv-view | `View` is the ancestor of ALL Django CBV.
