去另一个观点 [英] Going to another view
问题描述
def show(request):
protect(request)
...这里有更多的代码...
返回render_to_response
...
保护是另一个我正在导入的应用程序视图:from watch.actions import protect
在保护中,我做了一些检查,如果满足条件,我想使用render_to_response从保护,并防止返回显示。如果条件不符合,我想通常返回显示并继续执行代码。
我该怎么做?
谢谢。
如果它唯一的目的是你所描述的,你应该考虑写保护
作为视图装饰器。 此答案提供了一个如何执行此操作的示例。
基于查看我写过的装饰器,您的保护
装饰器可能看起来像:
from functools import fraps
from django.utils.decorators import available_attrs
def protect(func):
@wraps(func,assigned = available_attrs(func )
def inner(request,* args,** kwargs):
如果some_condition:
返回render_to_response('protected_template')
返回func(request,* args,* * kwargs)
返回内部
哪些可以让您使用它: p>
@protect
def show(request):
...
return render_to_response(.. 。)
Say I have the following view:
def show(request):
protect(request)
... some more code here...
return render_to_response
...
"protect" is another app view which I am importing like this: from watch.actions import protect
In protect, I make some checks and if a condition is met, I want to use render_to_response right from "protect" and prevent returning to show. If the condition is not met, I want to normally return to "show" and continue the code execution.
How may I do that?
Thanks.
If its only purpose is what you've described, you should consider writing protect
as a view decorator. This answer provides one example of how to do so.
Based on view decorators that I have written, your protect
decorator could look something like:
from functools import wraps
from django.utils.decorators import available_attrs
def protect(func):
@wraps(func, assigned=available_attrs(func))
def inner(request, *args, **kwargs):
if some_condition:
return render_to_response('protected_template')
return func(request, *args, **kwargs)
return inner
Which would allow you to then use it like:
@protect
def show(request):
...
return render_to_response(...)
