如何創建z3cform

我試圖重寫用於relateditems微件（靈巧所以z3cform）的新contenttreewidget這是從plone.formwidget.contenttree.widget進口MultiContentTreeWidget如何創建z3cform

我的問題是我不明白爲什麼我的示例試圖找到IDataConverter的組件，其中沒有用於contenttree小部件的IDataConverter，它是父級組件。

的代碼是：

#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))

而且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>

如果我想小部件，我有以下追蹤：

我曾經用這個類覆蓋了這個小部件，以便爲webmailer提供上傳功能。我想你想重寫json的生成來使這個jQuery兼容。非常感謝這項工作。

希望它幫助。
