4.2 SchemaとFTI

Schemaを書きます。

example.conference/example/conference/__init__.py

from zope.i18nmessageid import MessageFactory

_ = MessageFactory("example.conference")

example.conference/example/conference/presenter.py

from five import grok
from zope import schema

from plone.directives import form, dexterity

from plone.app.textfield import RichText
from plone.namedfile.field import NamedImage

from example.conference import _

class IPresenter(form.Schema):
    """A conference presenter. Presenters can be added anywhere.
    """
    
    title = schema.TextLine(
            title=_(u"Name"),
        )
    
    description = schema.Text(
            title=_(u"A short summary"),
        )
    
    bio = RichText(
            title=_(u"Bio"),
            required=False
        )
    
    picture = NamedImage(
            title=_(u"Picture"),
            description=_(u"Please upload an image"),
            required=False,
        )

example.conference/example/conference/program.py

from five import grok
from zope import schema

from plone.directives import form, dexterity
from plone.app.textfield import RichText

from example.conference import _

class IProgram(form.Schema):
    """A conference program. Programs can contain Sessions.
    """
    
    title = schema.TextLine(
            title=_(u"Program name"),
        )
    
    description = schema.Text(
            title=_(u"Program summary"),
        )
    
    start = schema.Datetime(
            title=_(u"Start date"),
            required=False,
        )

    end = schema.Datetime(
            title=_(u"End date"),
            required=False,
        )
    
    details = RichText(
            title=_(u"Details"),
            description=_(u"Details about the program"),
            required=False,
        )

example.conference/example/conference/session.py
サンプルはMessageFactoryのインポートが抜けているので書き足します。

from five import grok
from zope import schema

from plone.directives import form, dexterity
from plone.app.textfield import RichText

from example.conference import _

class ISession(form.Schema):
    """A conference session. Sessions are managed inside Programs.                              
    """

    title = schema.TextLine(
            title=_(u"Title"),
            description=_(u"Session title"),
        )

    description = schema.Text(
            title=_(u"Session summary"),
        )

    details = RichText(
            title=_(u"Session details"),
            required=False
        )

FTI(Factory Type Information)を書きます。

example.conference/example/conference/profiles/default/types.xml

<object name="portal_types">
 <object name="example.conference.presenter" meta_type="Dexterity FTI" />
 <object name="example.conference.program" meta_type="Dexterity FTI" />

</object>

example.conference/example/conference/profiles/default/typesというディレクトリを作成して、ファイルを追加します。

bin/buildoutして利用できるアドオンにします。

とりあえず、使えるようになりました。

ちなみに、TTWでファイルから作成したContent Typeを編集できるようになっています。

次回のハッカソンでも続けていきます。

ハッカソン後の懇親会で話をしているうちに、PyQtをやるべきだという気になってきました。
あとは、Common Lisp再開です。
