灵活地使用 Collective.z3cform.datagridfield

Question

我是 Plone 的新手，我正在尝试灵活地使用 DataGridField 。目标是使用 Plone 4.1 在我们的内网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），并且我想使用其中一个字段的数据网格来建模包含两列的表，显示结果摘要。

根据 collective.z3cform.datagridfield 中列出的说明，我已成功添加集体。 z3cform.datagrid Egg 添加到我的构建中的 Egg 列表中，我可以看到新的附加组件在我的网站附加组件列表中显示为“活动”。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，我还包括相应的 profile/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，而不是我已经添加的数据网格表小部件看到在Collective.z3cform.datagrid_demo 示例。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

您正在按照记录进行操作，但它不会起作用。这是一个已知问题：

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

这在 Plone 5.0.4 中对我有用

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,                      
    )
