使用方法名称进行金字塔遍历视图查找 [英] Pyramid traversal view lookup using method names

问题描述

在金字塔中使用遍历 url 查找时，是否可以让视图查找算法检查类的方法名称.例如，我可以这样做:

In pyramid when using traversal url lookup, is it possible to have the view lookup algorithm check for method names of a class. For example, I could do something like this:

@view_defaults(context=models.Group)
class GroupView(object):
    def __init__(self, context, request):
        self.context = context
        self.request = request

    @view_config(name='members')
    def members(self):
        pass

匹配比方说/groups/somegroup/members

有没有办法使名称查找部分动态化?也就是说，像这样:

Is there a way to make the name lookup part dynamic? That is, something like this:

@view_defaults(context=models.Group)
class GroupView(object):
    def __init__(self, context, request):
        self.context = context
        self.request = request

    def members(self):
        pass

    def add(self):
        pass

这样 /groups/somegroup/members 和 /groups/somegroup/add 都将解析为各自的类方法吗?

So that both /groups/somegroup/members and /groups/somegroup/add will both resolve to their respective methods of the class?

推荐答案

不能说这是 best 方式(我对金字塔一无所知)；但一种选择可能是用一个装饰器来装饰类，该装饰器适当地装饰方法名称.例如.

Can't say this is the best way (I don't know anything about pyramid); but one option might be to just decorate the class with a decorator that decorates the method names appropriately. eg.

import inspect

def config_wrap(func, name):
    @view_config(name=name)
    def wrapped(*args, **kwargs):
        return func(*args, **kwargs)
    return wrapped

def dynamic_names(cls):
    for name, m in inspect.getmembers(cls, inspect.ismethod):
        setattr(cls,name,config_wrap(m, name))
    return cls


@dynamic_names
@view_defaults(context=models.Group)
class GroupView(object):
    def __init__(self, context, request):
        self.context = context
        self.request = request

    def members(self):
        pass

    def add(self):
        pass
