我不认为这是Edit股票形式的使用案例。 您可重新命名包含该项目的夹件目录中的项目。 如果你想从ed的形式来做:

• You may need to use a custom edit form (subclass the existing form);
• name your id field something other than id , perhaps target_id or shortname
• have the __call__() method of the form update / save the form, and only on success rename the item within its container.
• __call__() should redirect to the new item s URL after edit that triggers a name change.

或许像(完全没有测试):

from plone.dexterity.browser.edit import DefaultEditForm as BaseForm
from Products.statusmessages.interfaces import IStatusMessages

class RenameEnabledEditForm(BaseForm):
    def __call__(self, *args, **kwargs):
         self.update(*args, **kwargs)
         data, errors = self.extractData()
         existing, newid = self.context.getId(), data.get( target_id )
         if not errors and existing != newid:
             parent_folder = self.context.__parent__
             if newid in parent_folder.objectIds():
                 raise RuntimeError( Duplicate object id )  # collision!
             parent_folder.manage_renameObject(existing, newid)
             newurl = parent_folder[newid].absolute_url()
             IStatusMessages(self.context).addStatusMessage(
                 u Renamed item from "%s" to "%s" in folder  % (existing, newid),
                 type= info ,
                 )
             self.request.response.redirect(newurl)
         else:
             return self.index(*args, **kwargs)

我用习惯添加表格实现了这一目的,只有添加形式包括id-field和edit形式t(通过更名为“行动”或从多重内容观点进行老调)。

一些锅炉:

from five import grok

from zope import schema

from plone.directives import form
from plone.directives import dexterity


class IMyContent(form.Schema):
    """Schema of MyContent"""


class NotValidId(schema.ValidationError):
    """Id is not valid."""


def isValidId(value):
    """Validates id for new MyContent objects"""
    # raise NotValidId(value)
    return True


class IMyContentAddForm(IMyContent):
    """Schema of MyContent Add Form"""

    form.order_before(id="*")
    id = schema.ASCIILine(
        title=u"Id",
        constraint=isValidId,
        required=True
        )


class MyContentAddForm(dexterity.AddForm):
    """Add Form for new MyContent objects"""
    grok.name("my.app.mycontent")

    label = u"Add New"
    schema = IMyContentAddForm

    def create(self, data):
        """Creates a new object with the given (validated) id"""
        id = data.pop("id")
        obj = super(MyContentAddForm, self).create(data)
        obj.id = id
        return obj

还有 开放问题及其初步工作,使Dexterity-types支持标准“关于内容的 Name?”-feature。
