Event on object deletion
|
|
||||||||||||
|
Hi everybody,
in my project, I create objects with Archetypes and additionally I have to store and delete these objects in an other system. On object creation I can use a subscription adapter like the example in Aspeli`s book <subscriber
provides="Products.Archetypes.interfaces.IObjectPostValidation"
factory=".cinema.ValidateCinemaCodeUniqueness"
/>to store them in the other system. On object deletion I need to delete also the object in the other system, but I can`t find an event interface, that is called on deletion. I tried to use OFS.interfaces.IObjectWillBeRemovedEvent and zope.app.container.interfaces.IObjectRemovedEvent, but they are not called. Does anyone know how if there is an interface, that is called on deletion or has another idea how to execute some code on object deletion? Thank you very much for your help :) |

This is not a good event to use. You should use the IObjectInitializedEvent from Archetypes. See chapter 9, on events. > On object deletion I need to delete also the object in the other system, but > I can`t find an event interface, that is called on deletion. > I tried to use > OFS.interfaces.IObjectWillBeRemovedEvent > and > zope.app.container.interfaces.IObjectRemovedEvent, but they are not called. Mmm.... they should be called, unless your deletion takes place using something other than _delObject() (the standard OFS API which Plone will call). You may, however, find that with linkintegrity installed, they're called twice. Once for the LI checks which results in an aborted transaction, and then again when you confirm the delete transaction. You need to be resilient to this and either check for the LI marker on the request, or make sure your external data store is transactional and hooks into the Zope transaction manager. > Does anyone know how if there is an interface, that is called on deletion or > has another idea how to execute some code on object deletion? IObjectRemovedEvent is definitely called when an object is deleted. Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.

Re: Event on object deletion

ok, thank you for your response.
I managed to register two subscribers for creation and deletion of Myobject: <subscriber
for="..interfaces.IObjectInterface
Products.Archetypes.interfaces.IObjectInitializedEvent"
handler=".myobject.storeMyObject" />
<subscriber
for="..interfaces.IObjectInterface
zope.app.container.interfaces.IObjectRemovedEvent"
handler=".myobject.deleteMyObject"
/>My problem is, that I need to store and delete entities of Myobject in a background system via webservice, and if something goes wrong on creation and deletion, I have to deal with this error, so that I don`t have local entities, that are not congruent with the background system. Is there a way to throw an exception or something like this, to deal with these erros? Or any other suggestions to realize this? This is my first plone project and I am not that experienced with plone and zope, so excuse my questions :) |

Well, the IObjectInitializedEvent won't get fired unless the edit succeeded, IObjectRemovedEvent won't be fired unless the object is being deleted. Note that with LinkIntegrity enabled, you may get the 'delete' event twice: once when the link integrity check takes place, and again when the transaction is confirmed. You'll need to handle that somehow, or turn off linkintegrity. That said, the only way to be properly transactional is to register a transaction manager with Zope and use that to synchronise commit or rollback in your external system. You can look at a transaction manager for SQLAlchemy here: http://svn.zope.org/zope.sqlalchemy/trunk/src/zope/sqlalchemy/ Note that this isn't entirely trivial, so if you can live with some risk of transactions getting out of sync, the simple event handler approach is a lot easier.

ok, writing an own transaction manager is too much for my business case, so
I think I will live with the risk of getting out of sync and find a workaround to deal with the situation, if both systems are not congruent. Martin, you mentioned, that I have to "... check for the LI marker on the request ...". How do I do this check? thank you for your efforts .... |

On deletion, the method I registered as a subscriber is called three times.
Martin mentioned, that I can check for a marker interface to recognize if the event is called from LinkIntegrity or another part of plone. I registered a subsriber for Products.Archetypes.interfaces.IObjectInitializedEventand for zope.app.container.interfaces.IObjectRemovedEvent The method signature for the notified delete-method is: @adapter(IMyObject, IObjectRemovedEvent) def deleteMyObject(self, event): Does anybody have an idea how I can check for the aforementioned marker, when this method is called?

Man, I am stuck in the same problem. I have to set an attribute of an object B, after deletion of object A, but: - using IObjectRemovedEvent, my def is called three times - none of these three call get attribute of B setted. It seems there is a roll-back and the transaction is not commited... I don't know. - I have no idea how to check this marker Regards, Felipe Roquette |

I would expect it to be called twice. Note that if you have a folderish type, children of the folder will also get the IObjectRemovedEvent. If you can do this, it'd be helpful: put a breakpoint in the handler: def myhandler(obj, event): import pdb; pdb.set_trace() Trigger the deletion. You should get the breakpoint three times (start Zope in foreground mode, obviously). Each time, do this: (pdb) pp obj (pdb) pp event (pdb) pp event.object (pdb) bt Paste the result of those three commands here. This will tell us (a) the context, (b) the exact event type, (c) the real object of the event and (d) the call stack up until the point where the event handler is called. Also paste your event handler registration (i.e. the ZCML + method signature). > - none of these thre e call get attribute of B setted. It seems there is a > roll-back and the transaction is not commited... I don't know. The way plone.app.linkintegrity works is this: 1. The deletion is attempted 2. An event handler checks if any links will be broken and marks those in a special field on the request 3. The transaction is aborted 4. The user is asked to confirm 5. If they confirm, the original request is replayed, but this time the event handler doesn't abort the transaction So, the last time, the transaction should definitely be committed. The reason it works like this, by the way, is that it's very hard otherwise to predict any and all situation in which there could be broken links. > - I have no idea how to check this marker Untested, but you can try something like this: from plone.app.linkintegrity.interfaces import ILinkIntegrityInfo def myhandler(obj, event): request = getattr(obj, 'REQUEST', None) realDelete = False if request is None: realDelete = True else: info = ILinkIntegrityInfo(request) if not info.integrityCheckingEnabled(): realDelete = True elif not info.getIntegrityBreaches(): realDelete = True elif info.isConfirmedItem(obj): realDelete = True if realDelete: # do your thing Cheers, Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.

Hello,
this is the registration of my subsriber: in configure.zcml: <subscriber handler=".tools.deleteMyObject" /> The function in tools.py: @adapter(IPartnerAngebot, IObjectRemovedEvent) def deleteMyObject(self, event): This is the result of my debug messages for the three times, that my function is called on deletion. I hope that you can read all lines, if not, I can try to upload a file with the messages. Called the first time: ------------------------------------------------------------------------ (Pdb) pp self

Well, references are deleted in an event handler too. References are stored centrally in the reference catalog. So depending on when your handler is called, that clearing may have happened already. There's an IBeforeObjectRemovedEvent that you can use too, where they should stay put. Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.
