Re: [Zope] Access object inside a folder

did u try that:

do what u want
/dtml-in
Hope this help
Bye

Hi,
I have put objects inside a folder tabledef and would like to refer them :
dtml-in "_.getitem('tabledef').objectItems(['DTML Document'])" sort=id
mapping
dtml-var "_['sequence-item']" html_quote
/dtml-in
However, this does not work, But putting the objects in the current folder
works without problems:
dtml-in "objectItems(['DTML Document'])" sort=id
dtml-var "_['sequence-item']" html_quote
/dtml-in
I also try:
dtml-with tabledef
dtml-in "objectItems(['DTML Document'])" sort=id
dtml-var "_['sequence-item']"
/dtml-in/dtml-with
and some other combinations, all without success.
How can I access the objects (DTML DOCUMENTS) inside a folder?
Moreover, I would like to do the following:
I have some properties of an object abc which have same name with the object
ids in the tabledef folder, I would also lookup the objects' properties :
dtml-in propertyMap mapping
dtml-with tabledef.id
dtml-var help
dtml-var taborder
/dtml-with
/dtml-in
Assume abc have a property address, then there should be a dtmldoc call
address in tabledef, which have properties "help" and "tableorder". I would
like to retrieve them.
Can somebody help me with these?
Rgs,
Kent Sin

This is as it should be:
"objectItems" does not return a list of mapping objects.
These objects do not have a mapping's "__getitem__"
method. Therefore, you get the AttributeError.
dtml-with tabledef
dtml-in "objectItems(['DTML Document'])" sort=id
dtml-var "_['sequence-item']"
/dtml-in
/dtml-with
Error Type: AttributeError

That is very strange!
The error message (including traceback) tells that
Zope tried to access "tabledef.__call__". This
was impossible, because "tabledef" has no "__call__" attribute.
The strange thing: your DTML snipped does not contain
any place, where Zope must access "tabledef.__call__".
Both in the "dtml-with" as well as in "_['sequence-item']",
Zope will see, whether the objects are callable and if
so, it will call them.
It seems that "callable" returns true, but in fact one of
the objects is indeed not "callable".
If I add mapping:
dtml-with tabledef
dtml-in "objectItems(['DTML Document'])" sort=id mapping
dtml-var "_['sequence-item']"
/dtml-in
/dtml-with
Error Type: AttributeError
Error Value: __getitem__
That is the same as in the first example.
Moreover, I would like to do the following:
I have some properties of an object abc which have same name with the
object
ids in the tabledef folder, I would also lookup the objects' properties
:
dtml-in propertyMap mapping
dtml-with tabledef.id
This will almost surely give a KeyError (tabledef.id).
You must enclose it in "...".
dtml-var help
dtml-var taborder
/dtml-with
/dtml-in
Assume abc have a property address, then there should be a dtmldoc call
address in tabledef, which have properties "help" and "tableorder". I
would
like to retrieve them.
I fear, I do not understand, what you want to do.
I have a folder call tabledef which use dtmldocument to keep some field
definition like its label, size, default value, help text etc. Which I would
like to generate the data entry form for it. The data will be stored as
object properties, so If I generate a edit form, then I should get the
property, lookup the field information in tabledef folder, and get the
label, size, information from there.
I am still not sure, what you are for.
But at least, I understand your partial problem: accessing the
content of a folder. I think I can help you with this.
When you look at the ObjectReference at URL:http://zdp.zope.org
(the Zope Documentation Portal), you will find that
"objectItems" returns a list of pairs "(id,subobject)".
"dtml-in" handles such list specially (- dtml-in reference):
it calls the first component "sequence-key" and the second
"sequence-item".
The following DTML code works for me (Zope 2.1.6):
dtml-in "tabledef.objectItems(['DTML Method'])" sort=sequence-key
h1dtml-var sequence-key-- the subobject's id--/h1
dtml-var sequence-item -- the subobject itself, rendered--
/dtml-in

You note, that your examples have an essential difference:
1 uses "mapping", 2 does not.

dtml-in "objectItems(['DTML Document'])" sort=id
