灵活的访问器和修改器方法

发布于 2024-12-27 16:23:17 字数 383 浏览 0 评论 0原文

我是敏捷的初学者（大约 2 天了）。我正在尝试在迁移网站的过程中将旧的内容类型迁移到灵活的内容。

经典原型中的模式定义就像

TextField('script',
          searchable=0,
          mutator="write",
          accessor="__call__",
          edit_accessor="document_src",
          widget=TextAreaWidget(label="Page Template script",rows=40,cols=40),

如何灵活地重新定义？我正在从 Plone 252 升级到 Plone 412。

问候，

I'm beginner user of dexterity (about 2 days now). I'm trying to migrate my old content type to dextertiy content in process of migrating website.

Schema defination in classic archetype is like

TextField('script',
          searchable=0,
          mutator="write",
          accessor="__call__",
          edit_accessor="document_src",
          widget=TextAreaWidget(label="Page Template script",rows=40,cols=40),

How can I redefine in dexterity ? I'm upgrading from Plone 252 to Plone 412.

Regards,

您必须从头开始创建一个新的 Dexterity 内容类型，并将 Archetype 的架构完全重写为继承自 plone.directives.form 并具有 zope.schema 字段类型的新架构。

例如，您的 Archetype 的架构字段声明将类似于就像 Dexterity 中的这样：

script = schema.TextLine(
        title=_(u"Page Template Script"),
    )

Dexterity 内容类型不会像 Archetypes 内容类型那样获得自动访问器和修改器。相反，您只需访问架构字段，就像它是一个属性一样。

例如：

script = myfolder.script

如果您想创建相同的访问器和修改器（就像您在 Archetypes 字段中指定的那样），则必须在 Dexterity 类上手动创建它们。

例如，类似：

class MyFolder(dexterity.Container):
    """ """
    grok.implements(IMyFolderSchema)

    def __call__(self):
        return self.script

    def edit_accessor(self):
        return self.script

    def write(self, value):
        self.script = value

You will have to create a new Dexterity content type from scratch and completely rewrite your Archetype's Schema to a new schema that inherits from plone.directives.form and with the field types form zope.schema.

For more information, see here:
http://plone.org/products/dexterity/documentation/manual/developer-manual/schema-driven-types/referencemanual-all-pages

For example, your Archetype's schema field declaration, will look like something like this in Dexterity:

script = schema.TextLine(
        title=_(u"Page Template Script"),
    )

Dexterity content types don't get automatic accessors and mutators like Archetypes content types. Instead, you just access the schema field as if it's an attribute.

For example:

script = myfolder.script

If you want to create the same accessors and mutator (like you specified in the Archetypes field), you'll have to create them manually on your Dexterity class.

For example, something like:

class MyFolder(dexterity.Container):
    """ """
    grok.implements(IMyFolderSchema)

    def __call__(self):
        return self.script

    def edit_accessor(self):
        return self.script

    def write(self, value):
        self.script = value
