I'd like to create a reusable schema-fragment so that content images are always
explicitly associated with alt text. I created an interface like this:
class INazImage(form.Schema):
"""
Just a NamedBlobImage with a built-in alt field
"""
image = NamedBlobImage(title=_(u"Image"))
alt = schema.TextLine(
title=_(u"Image Alternative"),
description=image_alt_description,
)
and I'm trying to use it like this, for example:
class IContact(form.Schema):
"""
A single contact entry
"""
image = schema.Object(
title=_(u"Contact Image"),
schema=INazImage,
)
name = schema.TextLine(title=_(u"Contact Name"))
title = schema.TextLine(title=_(u"Contact Title"))
department = schema.TextLine(title=_(u"Contact Department"))
email = schema.TextLine(title=_(u"Contact Email"))
phone = schema.TextLine(title=_(u"Contact Phone"))
notes = schema.Text(
title=_(u"Contact Notes"),
description=_(u"Notes, Other Positions, etc"),
)
class IContactPage(ICommonModulesSchema):
"""
A page that lists the contacts for a department.
"""
body = RichText(title=_(u"Body"), required=False)
contacts = schema.List(
title=_(u"Contacts"),
value_type=schema.Object(schema=IContact),
min_length=1,
)
The form appears to render well; however, as soon as I try to edit the list of
contacts in it, I get a 'Could not adapt' TypeError. I'd appreciate any
assistance in getting past this.
