Hi all,
I'm not able to find a clean way to get the class (the class object, not
only its name) implementing a portal_type.
In the past I followed a dirty approach, based on the portal_types tool
and relying on the assumptions that
- the name of the class was the same than the name of the portal type
- each class was defined in a separate module, with the same name than
the portal type, in the product registering the portal type.
I suppose that a more general method is available. Could somebody help me?
TIA.
Not sure this helps but if you have an instance of the type
you can do the following (dump from a debug session, 'contentdemo'
is a Plone site in my current dev env)
>>> site = app.contentdemo
>>> site
<PloneSite at /contentdemo>
>>> site.__class__
<class 'Products.CMFPlone.Portal.PloneSite'>
>>> site.__class__.__base__
<class 'Products.CMFDefault.Portal.CMFSite'>
>>> site.__class__.__bases__
(<class 'Products.CMFDefault.Portal.CMFSite'>, <class
'Products.CMFPlone.PloneFolder.OrderedContainer'>, <class
'Products.CMFDynamicViewFTI.browserdefault.BrowserDefaultMixin'>)
>>>
and further on
>>> about = site.about
>>> about
<ATFolder at /contentdemo/about>
>>> b = about.__class__.__bases__
>>> b
(<class 'Products.ATContentTypes.lib.autosort.AutoOrderSupport'>, <class
'Products.ATContentTypes.content.base.ATCTOrderedFolder'>)
>>> of = b[1]
>>> of
<class 'Products.ATContentTypes.content.base.ATCTOrderedFolder'>
>>> of.schema
<Products.Archetypes.Schema.Schema object at 0x90a29ac>
>>> of.schema.fields()
