[Zope] how to call sequence-item
Hello,
I'm using the photo-product, when one has created a photo-instance "image"
you can render this like so:
dtml-var "image(display='thumbnail')"
now I wanted to loop over all photos in a folder "Images" and did:
dtml-with Images
dtml-in "objectItems('Photo')"
dtml-call "REQUEST.set('bild',_['sequence-item'])"
dtml-var bildbr
/dtml-in
/dtml-with
that displays all photos in their original size, but
dtml-var "bild(display='thumbnail')"
gives:
Error Type: TypeError
Error Value: call of non-function (type string)
how can I call a sequence-item ?

Tres Seaver schrieb: I don't know how you calibrate your expectations, Chris, but conflict resolution is a property of (some) *storages*; the connectoins in application servers have nothing to do with it. For objects served from a ZEO storage, conflict resolution is only possible if: - The underlying storage is conflict resolving (FileStorage is; none of the others which ship with ZODB are). - The storage server can import the class of the object under conflict (this is why the BTrees code ships with ZODB, actually, so that the storage server can use its conflict resolution hooks). Installing the products containing application-defined conflict resolution on the storage server is the only way to enable that conflict resolution in a ZEO-backed deployment.

[Zope-dev] why does my externalmethod generate a ZODB transaction
Hi,
I wrote an external method from which I call a ZSQL-method, this runs fine
and returns the correct results, but when I look at the ZODB transactions,
I see that for each call of the method a transaction is recorded. Even
worse, when I make an error in my method, the folder from which I invoked
the method is no longer accesseble. I have to undo the transaction first,
that's how I found out that there is a transaction happening.
here is the code of the External-method:
import string
import sys
sys.path[0:0]=["/usr/local/Zope-2.1.4/Extensions"]
from DocumentTemplate import *
def dump(self,EA,**kwa):
#return EA,kwa
s = "br"
if hasattr(self,EA):
ea = apply(getattr(self,EA),(),kwa)
#return ea._names,"br",ea._schema
ead = ea.__dict__
for r in ead.keys():
s = s + r + "br"
i=getattr(ea,r)
if type(i) == type([]) and len(i) 0:
s = s + str(i) + " br "
for n in i:
s = s + str(n) + " | "
s=s+"br"
elif type(i) == type({}):
s = s + str(i) + " br "
for n in i.items():
s = s + str(n) + " | "
s=s+"br"
return s
def workform(self,REQUEST):
"Die Masken EinAusgabe"
scol = "movie_id"
sval = "a%"
srel = "like"
return dump(self,"Row_search",scol=scol,sval=sval,srel=srel)
this dumps the result of the ZSQL-method, I call it from a dtml-method
"testForm" like this:
dtml-var standard_html_header
dtml-var "RForm(REQUEST)"--- this calls workform
dtml-var standard_html_footer
when invoking this like .../Movies/testForm
I have an entry in the undoable transactions:
...Movies/testForm by super on Jul 4 at 21:21:31
By the way why is the day one day off the machine REDhat 6.2 Zope-2.1.4
has the correct date and shows now:
Wed Jul 5 21:49:01 CEST 2000

Re: [Zope-dev] why does my externalmethod generate a ZODB transaction
Hi, answering to myself, cause nobody else could find the reason in the code I provided, because I didn't include the real culprit.

[Zope-dev] why does an error in my externalmethod ...
make the folder from which it was invoked inaccessable ? continuing work on my external, I removed all modifications of self, so no transactions or better modifications of the ZODB took place. During the development cycle: editing the external methods, testing it through calling it through the browser, after editing the method the call of .../Movies/testForm resulted in a not found error. also I cannot enter the folder "Movies", if I click on it in the managementscreen, I also get the not found error. There is no transaction to undo, I restarted Zope no luck, I tried to delete the folder and get the error: Error Type: SystemError Error Value: Failed to import class setrecord from module __main__ (Object: manage_delObjects) File /usr/local/Zope-2.1.4/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_delObjects) File /usr/local/Zope-2.1.4/lib/python/OFS/ObjectManager.py, line 395, in manage_delObjects (Object: ElementWithAttributes) File /usr/local/Zope-2.1.4/lib/python/OFS/ObjectManager.py, line 267, in _delObject (Object: ElementWithAttributes) File /usr/local/Zope-2.1.4/lib/python/ZODB/Connection.py, line 396, in setstate SystemError: (see above) The class setrecord is in my external-method. I luckily had packed zodb shortly before that, and it is just a testserver. So I copied the Data.fs.old to Data.fs. Till now I could not reproduce the error. I still have the corrupted Data.fs. But I had that occure before, after making an error in the external method, the calling folder was not accessible anymore.

If more than one item is returned by this query, only the first will be used to supply data to your DataSkin. that was just left over from an reused query-template, I forgot to take it out. I also added a SkinScript method as a Data Plug-in in the defaultRack like this WITH QUERY readEvents(e_id=self.event_id) COMPUTE zeiten,firma,tel ,movie_id,movie_text,movie_link,movie_title ,datum_von,datum_bis,zeiten Do you have some way of providing self with an "event_id" value? Keep in mind that when DataSkins are created, they have only an "id" attribute, nothing else. So unless you have an attribute provider that provides an "event_id" value, this statement will fail. Perhaps what you actually mean is: WITH QUERY readEvents(e_id=self.id) COMPUTE event_id, zeiten,firma,tel, movie_id,movie_text,movie_link,movie_title, datum_von,datum_bis,zeiten Notice that I'm passing self.id to readEvents, and that I've added event_id to the list of attributes retrieved from the query. how do I set "self.id" I tried in dtml-method in the event-specialist: There is a event_id 609 in the table: dtml-var "getItem(_.int(609))" returns none or dtml-var "getItem(key=_.int(609))" returns none under the storage tab I selected for: Class to use for stored items: ZPatterns:DataSkin and Objects are: o stored persistently. x loaded by accessing attribute: event_id This will work fine, if you use the revised SkinScript above. You will probably want to create a ZClass subclass of DataSkin at some point to use instead, so that you can define permissions, methods, and so on for your Event objects.

to the sql query Create a default rack with the following
SkinScript.
WITH ['a','b','c'] COMPUTE movie_link=RESULT[0],movie_title=RESULT[1],
zeiten=RESULT[2]
Set the storage for this rack to be a DataSkin derived ZClass loaded by
accessing attribute 'movie_link'. Then try the following method in the Specialist:
dtml-var standard_html_header
dtml-let theItem="getItem('anyOldThing')"
dtml-with theItem
dtml-var movie_link
dtml-var movie_title
dtml-var zeiten
/dtml-with

If this does what you expect.. then you're getting close. Now change the
['a','b','c'] to be a call to your query:
WITH yourQuery(... parameters for your query... ) COMPUTE movie_link, movie_title...
etc.
If you get the same errors in the first case.. then your problem has
nothing to do with SQL.

If you are storing dataskins in a regular folder hierarchy (or other persistent hierarchy), you don't need racks. You just need a Folder w/Customization support in the objects' acquisition hierarchy. Of course, if you don't need DataSkin-ish behavior (i.e. triggers and attribute providers), you don't need the FwCS either. DataSkins stored outside of Racks will "pretend" to be ordinary persistent Zope objects if they can't find an appropriate Customizer. That is, they act like regular Zope objects, only it takes them more work because they're pretending. :) I created a FwCS and in it a customizer, but in my list of to customize object types are only meta_types listed, which have the Base class "_ZClass_for_DataSkin",. Is this a requirement, and if yes, is there a way to add this to existing ZClasses ? Mit freundlichen Grüßen Joachim Schmitz AixtraWare, Ing.

[Zope-dev] changing/storing Properties with ZPatterns
Hi,
I setup a Specialist with a ZCLass "AZ" for persistent storage. In AZ I
setup a Dataskin propertysheet "Basic" with properties Name, Street etc.
Now I made dtml-method form which iterates with:
dtml-call "REQUEST.set('ni',getItem(sid+id))"
dtml-in "ni.propertysheets.Basic.propertyMap()"
over the Basic propertysheet,builds the form, and stores the values within
another dtml-method edit with:
dtml-call
"ni.propertysheets.Basic.manage_changeProperties(REQUEST)"
this works fine. Now I wanted to have attributes which I don't want to
display in the form, for example complete attribute. I therefore created
another dataskin propersheet Internal in AZ with a property complete
and tried to set it with:
dtml-call
"ni.propertysheets.Internal.manage_changeProperties(REQUEST,complete='1')"
But I don't manage to store retrieve this attribute.
All attributes in the Basic propertysheet I can store and retrieve.
what is the magic behind this ?
Mit freundlichen Grüßen

I know that we use a variety of DataSkin propertysheets in our apps with no problems, although we are not using persistent storage at the present time. What happens when you try to store "complete"? Is it simply not saved, or do you get some kind of error? Have you tried other values? Have you checked your permissions to ensure your code has rights to change the "Internal" sheet? Its just silently ignored, everything in the Basic-sheet is stored correctly, and I set up the Internal sheet exactly as the Basic. I had the suspicion that only the Sheet listed first is used, but if I list it in the Sheet_Names of PersistentSheets it makes no difference. Mit freundlichen Grüßen Joachim Schmitz AixtraWare, Ing.

I saw a presentation in Paris by Juan David Palomar, of Localizer fame. (The presentation is now up at http://estce.act.uji.es:9673/localizer). The presentation impressed me on the need to get someone into the core of Zope that knows all these details, but also convinced me that the Zope3 effort needs to anticipate the needs of i18n and l10n. ZBabel and Localizer are good starts, but as jdavid says, both should be thought of as non-core projects that start influencing the core step-by-step. Hi! I fully agree that ZBabel and Localizer don't have to be core projects right now. But the core must be made fit for i18n to make sure that we don't have to patch things like the user folder implementation or the Help! button in the code. In Zopw 2.5, there still seem to be hot spots to fix with regard to i18n. Of course there are hot spots. I have asked multiple times for help on the mailing lists and the Eurozope site to identify such related hot spots. Also I had expect some input of the community regarding at unicode support inside Zope. But there has been no feedback. It looks like no one needs unicode support in Zope ?! :-) Anyway, as a first step Zope 2.5 provides full unicode support for the ZCatalog. I would like to see some volunteers that could help to set up a list of requirements (the list is almost there on the Eurozope site I think) and possible solutions that could be integrated into the Zope core. Referring to the open letter to zope-dev I could also charge the community for zero feedback. But this is not the place and time for flamewars. Instead we should bundle the power of ZC and the community. The opening of the CVS is a good starting point but I would like to see more people contributing.

To view a particular slide, you navigate to the subfolder, it automatically calls index_html, and there's your slide. All of the slides actually acquire their index_html DTMLDocument from high up on the food chain. The index_html in turn calls dtml-var body and the body is, of course, different for each slide. This is convenient, b/c each slide shares header/footer/etc. My problem is this. When you type in the URL of the top level folder (that is, the slideshow folder itself) I want Zope to behave as if you typed in the URL of the first slide automagically. The Slideshow product has an easy way to get our mitts on the firstSlide object, so that part is not a problem, but I cannot get it to work. Of course, if I create an index_html() method directly in my Slideshow.py, that screws up my acquisition. Zope dies with an infinite recursion.

What is to do, to enable marshalling of those types ?
You could hack xmlrpclib to marshall those object, but I dont recommend
it. Those objects can be big (but lazily evaluated), and you would be
opening a significant denial of service vulnerability in your server.
But it also can be very interesting for exporting data from a Zope site, to
be used in other applications.
I suggest you create a method (Python Script?) that makes the catalog
query, sanitizes the response by making sure it is not too big, and
returns a vanilla list or dictionary
I wrote a little pythonscript to export data from a ZPatterns Rack, where
the data is stored in a propertysheet:
res=context.Catalog()
t=[]
for m in sequence.sort(res,(('reg_id','cmp','desc'),)):
r=m.propertysheets.Basic.propertyItems()
t.append(r)
return t
This runs fine, when I test the script. But when I access it with xmlrpc, I
get:
Fault -1: Unexpected Zope exception: cannot marshal type 'None'
objects
I changed Zope xmlrpclib.py and added to the Marshaller class:
def dump_None(self, value):
self.write(valuestringNone/string/value\n)
dispatch[NoneType] = dump_None
Now that works, but I think the xmlrpclib.py, should be able to marshall
the None type.

The Item class mixes in Traversable, which is probably responsible for

If you need support for acquistion machinery (including __of__ which
creates wrappers), then you need to mix-in Acquisition.Implicit. The
SimpleItem class mixes this and Persistence in for you (along with
Item), so many Zope classes derive form SimpleItem. You need Persistence
to store instances of your class in the ZODB, and implicit acquisition
is the standard for Zope objects.
I actually don't know, if I need acquisition. The items are stored in the
btree of
the table, and I experienced no problems till now. I can copy and
export/import AixtraTable instances and the data is preserved.
In short I would recommend mixing in SimpleItem or you may find that your
objects are not stored properly in the ZODB.
Is that also true, if I store them in a btree ?

Re: [Zope-dev] Re: [Bug] ZODB invalidation processing
Hi, I was able to locate the places in the Zope-sources where the conflict error is triggered. On my local system it's in ZODB.FileStorage in the store-method there is if serial != cached_tid: rdata = self.tryToResolveConflict(oid, cached_tid,serial, data) in the tryToResolveConflict method of ZODB.ConnflictResolution there is: committed = state(self, oid, committedSerial, prfactory, committedData) print resolve, resolve resolved = resolve(old, committed, newstate) I found that the resolve-function raises an ConflictError exception, so I put an print there to find out which resolve function.

That is a real conflict: both transactions have inserted values into
the 'created' date index's '_index' under the same key, which can't be
resolved. Retrying the transaction is the only choice here.
Because DateIndexes convert the indexed value to an integer with
precision of one minute,
really one minute or do you mean second.
a date index on 'created' is fairly likely to
generate such conflicts when two parties both create content at the same
time.
But then I wonder how a CMF site could ever work, this error shows up
already on my lokal system when to users add something. On our live
system it is killing our portal ?
I would consider this a bug.
Ideally, one would examine the two values being inserted, note that they
were both IITreeSet instances containing one int apiece, and exploit our
knowledge of the application semantics to merge them, removing the
conflict; however, *because* they are IITreeSets, and therefore
separate persistent objects, their state is not available to the
bucket's '_p_resolveConflict', which must therefore lose.

Re: [Zope-dev] Re: [Bug] ZODB invalidation processing
Any suggestion for a temporary fix would be very welcome, since we get
about 6000 conflict errors per day now about 15 % unresolved, and they
are really killing our portal.
A workaround might be to replace the DateIndexes for 'created' and
'modified' with FieldIndexes: you will see a big jump in the number of
keys in the index, but (perhaps) a reduction in conflicts (altheough
there will be more bucket splits, which can also cause conflicts).
Unfortunately that does not work the FieldIndex also gives an conflict-error

A longer term solution might be to come up with a derived index type
which used non-persistent objects (rather than the IITreeSet used by
UnIndex) for the set of RIDs stored under each 'minute': you could then
inspect the state and do more aggressive conflict resolution than the
stock implementation allows (see my other post).
any other shortterm suggestions.

# Add the updated data:
record_data.update(data)
self.catalog_object(dict2ob(record_data), student_id)
where dict2obj does just that.
That updates the meta_data only on index_creation, and after a zope
restart the meta_data for registered_courses only contained the first
added course. That was because (i asume)
data.get(index, 0) always got the data from the index, and not from the
meta_data. I could veryfy this by looking at the catalog-record in the
ZMI. So it neve got to update the meta_data, so the real cause for
this problem is that data.get(index, 0), returns the value of the index
here and not that of the meta_data.

[Zope-dev] security problem in an monkey-patch
Hi, I have monkey-patched the QueueCatalog to adopt it to our needs, which works fine. I now wanted to introduce a new feature: The QueueCatalog should be bypassed during mass-import of data. So I introduced a new variable _bypass, and new getBypassQueue() and setBypassQueue methods in the monkey-patch: security.declareProtected(view_management_screens, 'getBypassQueue') def getBypassQueue(self): get _by_pass if not hasattr(self,_bypass): self._bypass = False return self._bypass security.declareProtected(view_management_screens, 'setBypassQueue') def setBypassQueue(self, bypass=False): set _bypass self._bypass = bypass from Products.QueueCatalog.QueueCatalog import QueueCatalog QueueCatalog.getBypassQueue = getBypassQueue QueueCatalog.setBypassQueue = setBypassQueue I can invoke these methods from the url like: ../portal_catalog/setBypassQueue?bypass=1 and ../portal_catalog/getBypassQueue displays a 1 But when I do a: input type=checkbox name=enable_bypass tal:attributes=checked here/portal_catalog/getBypassQueue / I get: Unauthorized: The container has no security assertions. Access to 'getBypassQueue' of (QueueCatalog at /uniben/portal_catalog) denied. What I am missing here. -- Gruß Joachim ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

I would write this as:
return getattr(self, '_bypass', False)
avoiding both write-on-read and hasattr in one fell swoop.
thanks for the tip.

I get:
Unauthorized: The container has no security assertions. Access to
'getBypassQueue' of (QueueCatalog at /uniben/portal_catalog) denied.

You need to supply security assertions for the new method you have adeed
to the class (your security assertions are being left behind in the
context where you defined the function).. Likely you can add another
attribute to the class, 'getBypassQueue__roles__', with the value being
a tuple, ('Manager',) (unless you want to figure out how to create a
PermissionRoles object yourself).
I solved it with:
QueueCatalog.getBypassQueue__roles__ = ['Manager', 'Owner',]
thanks for the help.

[Zope-dev] zeo and queuecatalog conflict-resolution
What is the recommended method to make the conflict-resolution-code available to the zeo-server ? Is there a Products directive for zeo.conf ? -- Gruß Joachim ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

I think it is sufficient that the Products directory is in the PYTHONPATH or available through sys.path. would something like: INSTANCE_PRODUCTS=/home/Zope/instances/waeup/Products ZODB3_HOME=/home/Zope/install/z296/lib/python PYTHONPATH=$ZODB3_HOME:$INSTANCE_PRODUCTS export PYTHONPATH INSTANCE_HOME in zeoctl do, and how can I check that it is realy effective ? -- Gruß Joachim ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
