使用敏捷的collective.z3cform.datagridfield
我对Plone有点新手，我试图用敏捷的DataGridField。 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），并且我想为其中一个字段使用datagrid来建模一个包含显示结果摘要的两列的表。
根据collective.z3cform.datagridfield中列出的说明，我已经成功将collective.z3cform.datagrid egg添加到我的build中的egg列表中，并且我可以看到新插件在我的加载项列表中显示为Active为我的网站。 我创建了一个简单的模式Python模块，它描述了一个文档，显示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
我已通过向profiles / default / types.xml添加一行来注册新的Interaction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>
当我为我的Interaction自定义类型添加表单时，我得到了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，敏捷列表小部件显示验证错误'系统无法处理给定值。'
是否有任何其他代码需要添加？ 我是否需要重写敏捷添加/编辑窗体视图模板？
你按照文件做事情，但不行。 这是一个已知的问题：

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,
)
这在Plone 5.0.4中适用于我

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

percentage = schema.TextLine(title=_(u'Percentage'),
required=False)
class IInteraction(model.Schema):
directives.widget(findings=DataGridFieldFactory)
findings= schema.List(
