自动完成和浏览 RelationChoice 字段在磁贴中不起作用

Autocomplete and browse for a RelationChoice field are not working in a tile

我有一个带有 RelationChoice 字段的磁贴,但该字段只有静态 html 表单元素(一个 "nothing" 单选按钮、一个文本输入和一个 'Search' 按钮),它不会动态响应。在将它与另一个有效网站上的相同磁贴进行比较时,我注意到来自 plone.formwidget.contenttree 和 plone.formwidget.autocomplete 的特定于字段的 js 代码未嵌入磁贴源中。我在 https://github.com/plone/plone.formwidget.autocomplete/blob/master/plone/formwidget/autocomplete/widget.py#L142 and in https://github.com/plone/plone.formwidget.contenttree/blob/master/plone/formwidget/contenttree/widget.py#L253 中放置了断点,它们在磁贴加载时被击中,并且返回了正确的 js。但是不知道为什么发不给客户端

有什么想法吗?

磁贴上的其他一切正常,标准 jquery 资源已加载:

++resource++plone.formwidget.autocomplete/jquery.autocomplete.min.js
++resource++plone.formwidget.autocomplete/formwidget-autocomplete.js
++resource++plone.formwidget.contenttree/contenttree.js

这是我的图块的 zcml:

  <plone:tile
      name="peps.tiles.calltoaction"
      title="PEPS call to action tile"
      description="A tile containing a full-size link, enclosing plain text"
      add_permission="cmf.ModifyPortalContent"
      schema=".tile.ICallToActionData"
      class=".tile.CallToActionTile"
      template="templates/calltoaction.pt"
      permission="zope2.View"
      for="*"
      />

这里是磁贴架构 class:

class ICallToActionData(IRichTextTileData):

    target = RelationChoice(
            title=_(u"Link target"),
            description=_(u'Choose the item to which this button will link'),
            source=UUIDSourceBinder(),
            required=False,
        )

    link_text = Text(
            title=_(u"Link button text"),
            description=_(u"The text for the link button at the bottom"),
        )



class CallToActionTile(RichTextTile):

    def target_url(self):
        url = None
        if self.data['target']:
            obj = uuidUtils.uuidToObject(self.data['target'])
            if obj is not None:
                if obj.portal_type == "Link":
                    site_url = getToolByName(obj, 'portal_url')()
                    if not obj.getRemoteUrl().startswith(site_url):
                        url = obj.getRemoteUrl()
                else:
                    url = obj.absolute_url()
        return url

    def link_text(self):
        return self.text_value('link_text')

问题的起因是这些重氮规则:

    <drop css:content="body script" />
    <after css:theme-children="html body" css:content="html body script" method="raw" />

如果 Diazo 主题处于活动状态,在调试问题时将其停用始终是个好主意。
