Schema and Field Management
===========================

  ($Id$)

  >>> from cybertools.composer.schema.schema import Schema
  >>> from cybertools.composer.schema.field import Field

We start with setting up a schema with fields.

  >>> serviceSchema = Schema()
  >>> serviceSchema.components.append(Field('title'))
  >>> serviceSchema.components.append(Field('description'))
  >>> serviceSchema.components.append(Field('start'))
  >>> serviceSchema.components.append(Field('end'))
  >>> serviceSchema.components.append(Field('capacity'))

For using a schema we need some class that we can use for creating
objects.

  >>> class Service(object):
  ...     pass

The schema will be connected with an object via an instance adapter.

  >>> from cybertools.composer.schema.instance import Editor
  >>> from zope import component
  >>> component.provideAdapter(Editor, (Service,), name="service.edit")

  >>> srv = Service()
  >>> inst = component.getAdapter(srv, name='service.edit')
  >>> inst.template = serviceSchema
  >>> inst.applyTemplate()
