Question

我有点像Plone的新手，我试图将DataGridField与Dexterity一起使用。目标是使用Plone 4.1在我们的Intranet上发布可用性研究的结果。我已经创建了一个自定义文档类型（称为交互），我想在其中一个字段中使用datagrid来建模一个包含两列显示结果摘要的表。

根据collective.z3cform.datagridfield中列出的说明，我已成功将collective.z3cform.datagrid egg添加到我的buildout中的egg列表中，我可以看到新的Add-on在我的列表中显示为Active我的网站的附加组件。我创建了一个简单的模式Python模块，它描述了一个文档，显示了我正在记录的可用性研究的结果：

from five import grok
from zope import schema
from zope import interface

from plone.directives import form

from plonetheme.mytheme import InteractionMessageFactory as _

from plone.app.textfield import RichText

from z3c.form import field, button
from Products.CMFCore.interfaces import IFolderish

from collective.z3cform.datagridfield import DataGridFieldFactory, DictRow

class IFinding(interface.Interface):
    summary = schema.TextLine(title=_(u"Summary"))
    percentage = schema.TextLine(title=_(u"Percentage"))

class IInteraction(form.Schema):

    findings = schema.List(
        title=_(u"Overview of findings"),
        required=False,
        value_type=DictRow(
            title=_(u"Finding"),
            schema=IFinding
            )
        )

class EditForm(form.EditForm):
    grok.context(IInteraction)
    grok.require('zope2.View')
    fields = field.Fields(IInteraction)

    fields['findings'].widgetFactory = DataGridFieldFactory

我通过在profiles / default / types.xml中添加一行来注册我的新交互内容类型：

<?xml version="1.0"?>
<object meta_type="Plone Types Tool" name="portal_types">
<property name="title">Controls the available content types in your portal</property>
<object meta_type="Dexterity FTI" name="interaction" />
<!-- -*- extra stuff goes here -*- -->
</object>

为了完整起见，我还包括相应的profiles / default / types / interaction.xml文件：

<?xml version="1.0"?>
<object name="interaction" meta_type="Dexterity FTI"
   xmlns:i18n="http://xml.zope.org/namespaces/i18n">
 <property name="title">Interaction</property>
 <property name="description">An item in the interactions dictionary</property>
 <property name="icon_expr">string:${portal_url}/document_icon.png</property>
 <property name="factory">interaction</property>
 <property name="link_target"></property>
 <property name="immediate_view">view</property>
 <property name="global_allow">True</property>
 <property name="filter_content_types">True</property>
 <property name="allowed_content_types"/>
 <property name="allow_discussion">False</property>
 <property name="default_view">view</property>
 <property name="view_methods">
  <element value="view"/>
 </property>
 <property name="default_view_fallback">False</property>
 <property name="add_permission">cmf.AddPortalContent</property>
 <property name="klass">plone.dexterity.content.Item</property>
 <property name="behaviors">
  <element value="plone.app.dexterity.behaviors.metadata.IDublinCore"/>
  <element value="plone.app.content.interfaces.INameFromTitle"/>
  <element value="collective.flowplayer.behaviors.IFlowplayerFile"/>
 </property>
 <property name="schema">plonetheme.mytheme.interaction.IInteraction</property>

 <property name="model_file"></property>
 <alias from="(Default)" to="(dynamic view)"/>
 <alias from="edit" to="@@edit"/>
 <alias from="sharing" to="@@sharing"/>
 <alias from="view" to="(selected layout)"/>
 <action title="View" action_id="view" category="object" condition_expr=""
    icon_expr="" link_target="" url_expr="string:${object_url}"
    visible="True">
  <permission value="View"/>
 </action>
 <action title="Edit" action_id="edit" category="object" condition_expr=""
    icon_expr="" link_target="" url_expr="string:${object_url}/edit"
    visible="True">
  <permission value="Modify portal content"/>
 </action>
</object>

当我转到我的交互自定义类型的添加表单时，我得到一个标准的敏捷列表项添加/删除小部件，而不是我在collective.z3cform.datagrid_demo示例中看到的datagrid表小部件。当我尝试保存自定义类型时，Dexterity列表小部件显示验证错误“系统无法处理给定值。”

我还需要添加其他代码吗？我是否需要覆盖Dexterity Add / EditForm视图模板？

Answer 1

你正在做文件记录，但它不起作用。这是一个众所周知的问题：

Answer 2

尝试使用Dexterity表单提示：

...
from zope import schema
from zope.interface import Interface

from plone.directives import form

from collective.z3cform.datagridfield import DataGridFieldFactory, DictRow

from plonetheme.mytheme import InteractionMessageFactory as _
...


class IFindingRow(Interface):
    summary = schema.TextLine(title=_(u'Summary'), 
                              required=False)
    percentage = schema.TextLine(title=_(u'Percentage'), 
                                 required=False)


class IInteraction(form.Schema):

    ...

    form.widget(findings=DataGridFieldFactory)
    findings= schema.List(
            title=_(u"Overview of findings"),
            value_type=DictRow(title=_(u"Finding"), 
                               schema=IFindingRow),
            required=False,                      
        )

Answer 3

这适用于Plone 5.0.4

bootstrap-slider.js v2.0.0

将collective.z3cform.datagridfield与Dexterity一起使用
