我正在尝试覆盖用于相关项目的小部件（敏捷性所以 z3cform），它是 from plone.formwidget.contenttree.widget import MultiContentTreeWidget

我遇到的问题是我不明白为什么我的示例尝试找到 IDataConverter 的组件，其中没有用于 contenttree 小部件的 IDataConverter 并且它是父级。

代码是：

#zope
from zope import interface
import z3c.form.interfaces
import z3c.form.widget
from Products.Five.browser.pagetemplatefile import ViewPageTemplateFile

#plone
from plone.formwidget.contenttree.interfaces import IContentTreeWidget
from plone.formwidget.contenttree.widget import MultiContentTreeWidget
from plone.app.relationfield.widget import RelationListDataManager

#internal


class DatalistManager(RelationListDataManager):
    pass


class IMultiDatalistWidget(IContentTreeWidget):
    """Datalist widget marker for z3c.form """


class MultiDatalistWidget(MultiContentTreeWidget):
    interface.implementsOnly(IMultiDatalistWidget)
    input_template = ViewPageTemplateFile('templates/datalist_input.pt')

    klass = u'html5-datalist-multiselection-widget'
    js_template = """\
    (function($) {
        $().ready(function() {
            console.log('autocomplete ready ?');
        });
    })(jQuery);
    """

    def js_extra(self):
        return ""


@interface.implementer(z3c.form.interfaces.IFieldWidget)
def MultiDatalistFieldWidget(field, request):
    """IFieldWidget factory for DatalistWidget."""
    return z3c.form.widget.FieldWidget(field, MultiDatalistWidget(request))

和zcml：

<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:z3c="http://namespaces.zope.org/z3c"
    i18n_domain="collective.z3cform.html5widgets">

    <include package="plone.app.relationfield" />

    <!--  TRY TO OVERRIDE IRelationList default from plone.app.relationfield -->

    <adapter factory=".widget_datalist.MultiDatalistFieldWidget"
           for="z3c.relationfield.interfaces.IRelationList
                .layer.Layer"
           />

</configure>

如果我正在尝试小部件，我有以下回溯：

I once overrode the widget with this class to enable an upload ability for a webmailer. I think you want to override the generation of the json to make this jQuery compatible. Thanks a lot for that work.

Here is my class: http://pastie.org/7923172

Hope it helps.
