Plone/Zope/Z3c-什么会导致publishTraverse"找不到页面？"

Question

我正在尝试获取z3c form.Form来填充其信息,而不是在url中创建get参数,我想使用publishTraverse.

所以这是我的代码的一部分:

my_object_view.py:

class EditMyObject(form.Form):
   fields = field.Fields(IMyObject)
   ignoreContext = False

   myObjectID = None

   def publishTraverse(self, request, name):
       print "Is this firing?"
       if self.myObjectID is None:
           self.myObjectID = name
           return self
       else:
           raise NotFound()

   def updateWidgets(self):
       super(EditMyObject,self).updateWidgets()
       #set id field's mode to hidden

   def getContent(self):

       db_utility = queryUtility(IMyObjectDBUtility, name="myObjectDBUtility")
       return db_utility.session.query(MyObject).filter(MyObject.My_Object_ID==self.myObjectID).one()

   #Button handlers for dealing with form also added

.....
from plone.z3cform.layout import wrap_form
EditMyObjectView = wrap_form(EditMyObject)    

在我的浏览器文件夹中的configure.zcml文件中:

<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:five="http://namespaces.zope.org/five"
    xmlns:genericsetup="http://namespaces.zope.org/genericsetup"
    xmlns:zcml="http://namespaces.zope.org/zcml"
    xmlns:browser="http://namespaces.zope.org/browser"
    i18n_domain="my.object">

    <browser:page
        name="myobject-editform"
        for="*"
        permission="zope2.View"
        class=".my_object_view.EditMyObjectView"
    />

</configure>

当我在url中使用get参数时,我能够使它正常工作,但是当我尝试使用publishTraverse时,我得到了找不到页面的错误.什么是奇怪的是什么时候

当我尝试使用发布遍历时,这就是我的url看起来的样子:

http://localhost:8190/MyPloneSite/@@myobject-editform/1

当我省略1,但保留"/"时,它仍然找到页面.我做错了什么导致了这个？

除非您声明视图提供了IPublishTraverse接口,否则Zope发布者不会调用publishTraverse.您需要将其添加到您的班级:

from zope.publisher.interfaces.browser import IPublishTraverse
from zope.interface import implementer

@implementer(IPublishTraverse)
class EditMyObject(form.Form):
    etc...

您还需要摆脱包装器视图.使用包装器,Zope遍历包装器,检查它是否提供IPublishTraverse,发现它没有,并放弃.相反,只需将表单直接注册为视图:

<browser:page
    name="myobject-editform"
    for="*"
    permission="zope2.View"
    class=".my_object_view.EditMyObject"
/>
