in current Zope versions python decimals are security proxied.
(See also http://www.zope.org/Collectors/Zope3-dev/543 )
I think a better solution than the one described in the bug is the
following:
Write an interface IDecimal which includes alle the mehtods you want to
access in views and page tempates.
Put the following into your configure.zcml:
class class=decimal.Decimal
implements interface=.interfaces.IDecimal /
allow interface=.interfaces.IDecimal /
/class
It declares that the class decimal.Decimal implements your IDecimal
interface and that there are no security restrictions on the interface.

Re: [Zope3-Users] Adapting multiple times
Am Mittwoch, den 05.04.2006, 08:48 +0200 schrieb Frank Burkhardt: Hi, I've got objects implementing interface IMyObject and two adapters: IMyObject - ISearchable ISearchable - ISearchableEN I would like to use a TextIndex to do fulltext search on objects implementing ISearchableEN . Unfortunately this doesn't work. The TextIndex tries something like this to adapt an object to the given interface: ISearchableEN(myobject) Which fails (Unable to adapt) because there is no adapter IMyObject - ISearchableEN and Zope doesn't try to adapt multiple times ( IMyObject - ISearchable - ISearchableEN ). Does anyone have an Idea how to do this or do I have to modify the TextIndex? Idea: Write an adater which Adapts IMyObject to ISearchableEN. This Adapter can be a function which only does the adaption chain and returns the Adapter to ISearchableEn adapter.

Re: [Zope3-Users] principalfolder breaks manager
Am Donnerstag, den 30.03.2006, 17:58 +0200 schrieb Frank Burkhardt: Hi, after adding a principal folder, the manager principal is no longer valid. That's bad, because I'm unable to remove the principal folder again (at least without pdb or 'zopectl debug'). Is there a special reason for that behaviour or do i miss something (like: you have to install utility XY before adding/registering the principal folder)? I added a principal 'test' to the folder (prefix='mpgsite') and a line like this to zcml: grantAll principal=mpgsite.test / You can only do a grantAll for users defined via ZCML. All other users you have to do zope.app.securitypolicy.principalpermission \ import principalPermissionManager principalPermissionManager.grantAllPermissionsToPrincipal(mpgsite.test) -- Mit freundlichen Grüßen Michael Howitz ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] DropdownWidget with SimpleVocabulary causes ConversionError.
Am Montag, den 27.03.2006, 18:31 +0900 schrieb [EMAIL PROTECTED]: I'd like to ask one more question. Why does SimpleVocabulary.fromValues/fromItems() not set 'title' ? Is there any good reason? Current implementation is unconvenient for non-ascii people. Sure. Maybe a new method is needed which gets tuples of length three which sets value, token and title. Otherwise you can write a subclass of SimpleVocabulary which is more convenient for non-ascii people. (Maybe there is a reason why it is called 'simple' ;-) mac ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Am Montag, den 27.03.2006, 11:52 +0900 schrieb [EMAIL PROTECTED]: Hi, I got a ploblem with SimpleVocabulary/SimpleTerm. Here is the situation of that. (1) I used Zope3.2 on Windows XP. (2) I made : a vocabulary, and a Choice field with the vocabulary, and a schema contains the field, and an add-form using the schema. (3) the vocabulary was made using SimpleVocabulary.fromValues(). with values which are all unicode strings(japanese). Hi, Vocabularies hav three levels: value: which is stored in ZODB token: which is used as value attribute of the option tag in HTML-Page. It must be convertable to str with ASCII encoding because when the conversion is done the encoding of the page is not yet known. (Correct me if I'm wrong here) title: which is dislpayed to the user as the contents of the option tag SimpleVocabulary.fromValues uses the values as value, token and title, so it is only useable with ASCII values. So you have to do it like this way: SimpleVocabulary(SimpleTerm(value, token, title), ...) token might be the uid of value, if it is an object which is stored in ZODB. -- mac ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

In unittests the ZCML-Directives are not used so you have to do the
things from ZCML in your test-code before adaption.
