使用带敏捷的collective.z3cform.datagridfield

Question

我是 Plone 的新手，我正在尝试将 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。我创建了一个自定义文档类型（称为交互），并且我想对其中一个字段使用数据网格来对包含两列显示结果摘要的表格进行建模。

按照collective.z3cform.datagridfield 中列出的说明，我已成功将collective.z3cform.datagrid 鸡蛋添加到我的构建中的鸡蛋列表中，并且我可以看到新插件在我的插件列表中显示为活动-我的网站。我创建了一个简单的模式 Python 模块，它描述了一个显示我正在记录的可用性研究结果的文档：

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

我已通过向profiles/default/types.xml 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，我还包含了相应的配置文件/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，而不是我在集体.z3cform.datagrid_demo 示例中看到的数据网格表小部件。当我尝试保存自定义类型时，敏捷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

您正在按照文档中的方式进行操作，但它不起作用。这是一个已知问题：

Answer 2

尝试使用敏捷表单提示：

...
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

这在 Plone 5.0.4 中适用于我

from zope import schema 
from zope.interface import Interface
from plone.supermodel import model
from plone.autoform import directives
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(model.Schema):
    directives.widget(findings=DataGridFieldFactory)
    findings= schema.List(
        title=_(u"Overview of findings"),
        value_type=DictRow(title=_(u"Finding"), 
                           schema=IFindingRow),
        required=False,                      
    )
