The modified model_source of a dexterity type is not available for other clients until the other client restarts.
Invalidating or clearing the SCHEMA_CACHE is not a working solution: every client seems to have its own SCHEMA_CACHE which afik cannot be cleared or invalidated from another client.
Is there any solution to solve this problem?
The scenario presented here uses ipython as second client. The same can be reproduced through the web by starting two clients: (1) create a dexterity type in client1, and (2) edit the XML Field Model in client2.
I'd like to put this as an issue on https://github.com/plone/plone.dexterity but as for today issues seem not to be available in the plone.dexterity github project

I have successfully sent a request using GetReservationRQ. Asking for the remarks sections but I am getting the result above which I would expect. (I assumed this is the right section and have tried Itinerary too, see below)

Which returns 2 remarks as part of the response:

</RemarkLines>
</Remark>
</Remarks>
However as you can see they are not the same remark as when I run the command I¥. What am I doing wrong?
Here are links to the sabre documentation:
https://developer.sabre.com/docs/soap_apis/management/itinerary/Retrieve_Itinerary/help_doc?page=get-reservation-request-and-response-structure
Which says:
REMARKS Allows to display remark information (supported types: REG, HD, HS, CLIADR, DELADR, INVOICE, ITINERARY, INTERFACE, CODED_A, PRTONTKT, CORPORATE, FOP, QQ, FILLER, ITINSEGASSOC)
I have an interface:
class ISomething(Interface):
something = schema.Dict(
title=u"Something",
description=u"Define something.",
key_type=schema.TextLine(title=u"Some Title"),
value_type=schema.Text(title=u"Some Text"))
used to create a form that saves values in registry (ControlPanelFormWrapper, RegistryEditForm).
In registry.xml:
<record name="something">
<field type="plone.registry.field.Dict">
<title>Something</title>
<key_type type="plone.registry.field.TextLine" />
<value_type type="plone.registry.field.Text" />
</field>
</record>
It's working: I can add key-value items {'Some Title': 'Some Text'}.
I need to modify my form to have multiple fields instead of Some text, but keeping the Dict. Example:
{'Some Title': {
'field_1': 'Value 1',
'field_2': 'Value 2'
}
}
I expect this to work then:
registry = getUtility(IRegistry)
reg_something = registry.get("something")
print reg_something['Some Title']['field_1']
>>> Value 1
So, how to change my interface and registry record to have the form updated in this way?
This is described in an article from Mark van Lent:
https://www.vlent.nl/weblog/2011/09/07/dict-list-value-ploneappregistry/
Adjust the registry.xml accordingly, exchange the record-name with yours:
<record name="my.package.example">
<field type="plone.registry.field.Dict">
<title>Verification filesnames</title>
<key_type type="plone.registry.field.TextLine">
<title>Key</title>
</key_type>
<value_type type="plone.registry.field.List">
<title>Value list</title>
<value_type type="plone.registry.field.TextLine">
<title>Values</title>
</value_type>
</value_type>
</field>
<value purge="false" />
See also this question where Luca Fabbri and Gil Forcada each provide alternative approaches, which might be true time-savers on the long term:
Plone- How can I create a control panel for a record in registry that is a dictionary type?
registry.xml in my default profile (imported with an upgrade step):
<registry>
<records interface="my.package.something.ISomethingItems">
<record name="mypackage_multiplesomething">
<field type="plone.registry.field.List">
<title>Something Items</title>
<value_type type="collective.z3cform.datagridfield.DictRow">
<schema>my.package.something.ISomething</schema>
</value_type>
</field>
</record>
</records>
</registry>
In something.py just define the interfaces:
from collective.z3cform.datagridfield import BlockDataGridFieldFactory
from collective.z3cform.datagridfield.registry import DictRow
from plone import api
from plone.app.registry.browser.controlpanel import ControlPanelFormWrapper
from plone.app.registry.browser.controlpanel import RegistryEditForm
from plone.autoform import directives
from zope import schema
from zope.interface import Interface
from zope.interface import implementer
from zope.schema.interfaces import IVocabularyFactory
from zope.schema.vocabulary import SimpleTerm
from zope.schema.vocabulary import SimpleVocabulary
class ISomething(Interface):
id = schema.ASCIILine(
title=u"Something ID",
description=u"Some description."
)
text = schema.Text(
title=u"A text field",
description=u"Human readable text"
)
url = schema.URI(
title=u"An URL",
description=u"Don't forget http:// or https://"
)
class ISomethingItems(Interface):
# the field is the same used in registry.xml
mypackage_multiplesomething = schema.List(
title=u"Something Items",
description=u"Define something items",
value_type=DictRow(title=u"Something", schema=ISomething)
)
directives.widget(mypackage_multiplesomething=BlockDataGridFieldFactory)
Now we can have an edit form (in something.py):
class SomethingItemsEditForm(RegistryEditForm):
schema = ISomethingItems
label = u"Something items definition"
class SomethingItemsView(ControlPanelFormWrapper):
""" Something items edit form """
form = SomethingItemsEditForm
defined as browser page (configure.zcml):
<browser:page
name="something-items-settings"
for="Products.CMFPlone.interfaces.IPloneSiteRoot"
class=".something.SomethingItemsView"
permission="cmf.ManagePortal"
/>
Easy to get the values from registry using api:
>>> from plone import api
>>> reg_something_items = api.portal.get_registry_record(
'mypackage_somethingitems', interface=ISomethingItems)
[{'id': 'some id', 'text': 'some text', 'url': 'http://something.com'}, {'id': 'some id other', 'text': 'some text other', 'url': 'http://something-other.com'}]
>>> item = reg_something_items[0]
{'id': 'some id', 'text': 'some text', 'url': 'http://something.com'}
>>> item['id']
some id
>>> item['text']
some text
>>> item['url']
http://something.com
If you added an uninstall profile to your product it is a good idea to add registry.xml in it:
<registry>
<record name="my.package.something.ISomethingItems.mypackage_somethingitems"
delete="True" remove="True" />
</registry>
to be sure the registry will be clean after uninstall.
You can check anytime the values you have in registry in SITE/portal_registry (Site Setup -> Configuration Registry)
I'm developing an add-on package which introduces a few Archetypes-based content types;
these are defined in the default profile of that package.
After (re-) installing my package in the Quick-Installer, I can see my types in the types tool; but I can't add them TTW, and they are not listed in the folder_constraintypes_form. I did select them in the "Allowed content types" multiselect list of the Folder portal type.
Since I got a ValueError from FactoryTypeInformation._getFactoryMethod in an bin/instance debug session, I "developed" Products.CMFPlone (branch 2.2) and changed the TypesTool.py like so:
from pprint import pprint # ADDED
...
class FactoryTypeInformation(TypeInformation):
...
def _getFactoryMethod(self, container, check_security=1):
if not self.product or not self.factory:
raise ValueError, ('Product factory for %s was undefined' %
self.getId())
pd = container.manage_addProduct # ADDED
p = container.manage_addProduct[self.product]
self_product = self.product # ADDED
self_factory = self.factory # ADDED
m = getattr(p, self.factory, None)
if m is None:
pprint(locals()) # ADDED
raise ValueError, ('Product factory for %s was invalid' %
self.getId())
if not check_security:
return m
if getSecurityManager().validate(p, p, self.factory, m):
return m
raise AccessControl_Unauthorized( 'Cannot create %s' % self.getId() )
The debug session now looks like this:
>>> root = app.plone
>>> from Products.CMFCore.utils import getToolByName
>>> tmp_folder = root.temp
>>> type_name = 'MyType'
>>> types_tool = getToolByName(tmp_folder, 'portal_types')
>>> type_info = types_tool.getTypeInfo(type_name)
>>> type_info
<DynamicViewTypeInformation at /plone/portal_types/MyType>
>>> new_content_item = type_info._constructInstance(tmp_folder, 'shiny_new_object')
{'check_security': 0,
'container': <ATFolder at /plone/temp>,
'pd': <App.FactoryDispatcher.ProductDispatcher object at 0x227afd0>,
'p': <App.FactoryDispatcher.FactoryDispatcher object at 0x7b97450>,
'self': <DynamicViewTypeInformation at /plone/portal_types/MyType>,
'm': None,
'self_factory': 'addMyType',
'self_product': 'MyCompany.MyProduct'}

So, the FactoryDispatcher lacks the necessary addMyType attribute.
Probably my declarations are incomplete?

Should not Archetypes take care of creating that missing addMyType method?
What could make this fail?
Is there something obviously missing in my configuration?
The site contains Archtypes-based objects exclusively so far. Will I come into trouble if I add Dexterity-based types now? ''(I'm totally inexperienced with Dexterity)''
Before someone tells me to do so: I created a question in the Plone community forum already; no luck so far. If important information comes in on either page, I'll sync it.
These are the missing parts to make your contenttype addable:
1.) Register the content-directory in MyCompany/MyProduct/configure.zcml by adding:
<include package=".content" />
2.) Add the file MyCompany/MyProduct/content/configure.zcml with this content:
<configure
xmlns="http://namespaces.zope.org/zope"
xmlns:five="http://namespaces.zope.org/five"
i18n_domain="MyCompany.MyProduct">
<class class=".mytype.MyType">
<require
permission="zope2.View"
interface="..interfaces.IMyType"
/>
</class>
</configure>
3.) Fix the then occurring syntax-error in MyCompany/MyProduct/content/mytype.py by replacing class MyType(*basecls) with class MyType(ATCTContent).
And last but not least remove the former attempts of making things work. Best would be to outsource the type to a dedicated pckg and create it with zopeskel, imo.
For the view-error occurring after adding a type, feel free to open a new quest ;-)
In our use case, if the title of an unpublished object is modified we would like to change its id according with the new title.
We try to accomplish it using a simple subscriber without success:
ZCML:
<configure
xmlns="http://namespaces.zope.org/zope"
xmlns:zcml="http://namespaces.zope.org/zcml">
<subscriber
for="DummyContentType
zope.lifecycleevent.IObjectModifiedEvent"
handler=".subscriber.update_id"
/>
</configure>
Python:
# -*- coding: utf-8 -*-
from plone import api
from plone.i18n.normalizer.interfaces import IIDNormalizer
from zope.component import queryUtility
def update_id(obj, event):
state = api.content.get_state(obj)
if state != 'private':
return
util = queryUtility(IIDNormalizer)
new_id = util.normalize(obj.Title())
api.content.rename(obj=obj, new_id=new_id, safe_id=True)
obj.reindexObject()
When this code run we get an ResourceLockedError exception
I'm creating a fork of my Plone site (which has not been forked for a long time). This site has a special catalog object for user profiles (a special Archetypes-based object type) which is called portal_user_catalog:
$ bin/instance debug
>>> portal = app.Plone
>>> print [d for d in portal.objectMap() if d['meta_type'] == 'Plone Catalog Tool']
[{'meta_type': 'Plone Catalog Tool', 'id': 'portal_catalog'},
{'meta_type': 'Plone Catalog Tool', 'id': 'portal_user_catalog'}]
This looks reasonable because the user profiles don't have most of the indexes of the "normal" objects, but have a small set of own indexes.
Since I found no way how to create this object from scratch, I exported it from the old site (as portal_user_catalog.zexp) and imported it in the new site. This seemed to work, but I can't add objects to the imported catalog, not even by explicitly calling the catalog_object method. Instead, the user profiles are added to the standard portal_catalog.
Now I found a module in my product which seems to serve the purpose (Products/myproduct/exportimport/catalog.py):
"""Catalog tool setup handlers.
$Id: catalog.py 77004 2007-06-24 08:57:54Z yuppie $

body = context.readDataFile(filename)
if body is not None:
importer.filename = filename # for error reporting
importer.body = body
if getattr(obj, 'objectValues', False):
for sub in obj.objectValues():

site = context.getSite()
obj = getToolByName(site, 'portal_user_catalog', None)
if tool is None:
logger = context.getLogger('catalog')
logger.info('Nothing to export.')
return
parent_path=''
exporter = queryMultiAdapter((obj, context), IBody)
path = '%s%s' % (parent_path, obj.getId().replace(' ', '_'))

if body is not None:
context.writeDataFile(filename, body, exporter.mime_type)
if getattr(obj, 'objectValues', False):
for sub in obj.objectValues():
exportObjects(sub, path+'/', context)
I tried to use it, but I have no idea how it is supposed to be done;
I can't call it TTW (should I try to publish the methods?!).
I tried it in a debug session:
$ bin/instance debug
>>> portal = app.Plone
>>> from Products.myproduct.exportimport.catalog import exportCatalogTool
>>> exportCatalogTool(portal)
Traceback (most recent call last):
File "<console>", line 1, in <module>
File ".../Products/myproduct/exportimport/catalog.py", line 58, in exportCatalogTool
site = context.getSite()
AttributeError: getSite
So, if this is the way to go, it looks like I need a "real" context.
Update: To get this context, I tried an External Method:
# -*- coding: utf-8 -*-
from Products.myproduct.exportimport.catalog import exportCatalogTool
from pdb import set_trace
def p(dt, dd):
print '%-16s%s' % (dt+':', dd)
def main(self):
"""
Export the portal_user_catalog
"""
g = globals()
print '#' * 79
for a in ('__package__', '__module__'):
if a in g:
p(a, g[a])
p('self', self)
set_trace()
exportCatalogTool(self)
However, wenn I called it, I got the same <PloneSite at /Plone> object as the argument to the main function, which didn't have the getSite attribute. Perhaps my site doesn't call such External Methods correctly?
Or would I need to mention this module somehow in my configure.zcml, but how? I searched my directory tree (especially below Products/myproduct/profiles) for exportimport, the module name, and several other strings, but I couldn't find anything; perhaps there has been an integration once but was broken ...
So how do I make this portal_user_catalog work?
Thank you!
Update: Another debug session suggests the source of the problem to be some transaction matter:
>>> portal = app.Plone
>>> puc = portal.portal_user_catalog
>>> puc._catalog()
[]
>>> profiles_folder = portal.some_folder_with_profiles
>>> for o in profiles_folder.objectValues():
... puc.catalog_object(o)
...
>>> puc._catalog()
[<Products.ZCatalog.Catalog.mybrains object at 0x69ff8d8>, ...]
This population of the portal_user_catalog doesn't persist; after termination of the debug session and starting fg, the brains are gone.
It looks like the problem was indeed related with transactions.
I had
import transaction
...
class Browser(BrowserView):
...
def processNewUser(self):
....
transaction.commit()
before, but apparently this was not good enough (and/or perhaps not done correctly).
Now I start the transaction explicitly with transaction.begin(), save intermediate results with transaction.savepoint(), abort the transaction explicitly with transaction.abort() in case of errors (try / except), and have exactly one transaction.commit() at the end, in the case of success. Everything seems to work.
Of course, Plone still doesn't take this non-standard catalog into account; when I "clear and rebuild" it, it is empty afterwards. But for my application it works well enough.
