[ZPT] ZPT served from a python Product / where are my attr. gone ?

Thu, 19 Jul 2001 17:36:56 +0200

Hi,
perhaps my Problem is easy to solve, but perhaps ...

let=B4s start
I am trying to create an object on the fly with data out of an=20
SQL-Method.
The Object i am creating is an Instance of an class.
Let=B4s asume
myFolder =3D DeTeLineFolder()
First round:

1. Via my URL ..../myfolder/index_html  -- i get my standard index_html
2. Via my URL ..../myfolder/213
-- i get the index_html from the class Document. With the values of my=20=

Query. works ok

Round 2:
1. the same
2. the same, but i used ZPT (PageTemplateFile) an i get the following=20
message

Error Type: Undefined
Error Value: "doc_type" not found in "here/doc_type"

I tried alle namespaces !!!!!!(container ... )  But i think it has to be=20=

"here" ?

more trace back below !

Question ::::

Why is "here" empty ?

How can i put something in it ?

Why is DTML working, but not ZPT ?

The Code :::::::::::::::::::::::::::::::::::::::::::::::

class Document(Acquisition.Implicit):
	"""I am Used"""

	def __init__(self, TMP=3DNone):
		"""Zuweisung aller Objektproperties aus einer =
SQL-Abfrage"""
		self.id2 =3D str(TMP[0]['id'])
		self.doc_type =3D str(TMP[0]['doc_type'])#The thing i am =
trying=20
to access
=09
#the 2 cases ######

#round 1=09
	templateFile =3D HTMLFile("Templates/test", globals() )
#round 2
	templateFile =3D PageTemplateFile("Templates/test", globals() )

#end

	def index_html(self):
		"""dfdd"""
		return self.templateFile(self)=09
	=09
	def it(self):
		"""dfdd"""
		#return self.hallo
		return self.templateFile(self)

class DeTeLineFolder( Folder ):
	"""The Caller"""
=09
	meta_type =3D 'DeTeLineFolder'
=09
	_isDeTeLineFolder =3D 1
=09
=09
	def __getitem__(self, attr):
		"""Get all request which could not resolved after =
Acquesition"""
		#attr =3D string.split(attr, '.')[0]
		TMP =3D self.SQL.getDocbyRed_Query(r_red_id =3D attr)

		self._v_Docu_Instace =3D Document(TMP)
		return self._v_Docu_Instace
	=09
	hallo =3D "Hallo Michael"

	and so on ......
