Wizards?
by Peter Arvidsson 10 Jul '00

10 Jul '00

I am trying to create wizards but as usual I am running into problems.. To forward input to the next step I learned in the howto "Wizards made easy" that this was the way to do it: <dtml-in "REQUEST.form.items()"> <input type="hidden" name="<dtml-var sequence-key>" value="<dtml-var sequence-item>"> </dtml-in> When I type that code in however I get the following error message: Error Type: TypeError Error Value: illegal argument type for built-in operation Is the howto wrong or did I do something wrong? Wizards are prebuilt but where do I change how wizards should react. For example where do I change the caption on the "next"-button or the "title"-output? Peter

Add a new atrribute to a record
by Marcel Preda 10 Jul '00

10 Jul '00

Hi I have a variable `x' , type is `instance' -record-, was created with something like http://host/page?x.attr1:record=Value1 I want to add a new attribute `attr2', in Zope something similar with:<dtml-call "REQUEST.set('var',Expresion)"> OR (python ) x.attr2=VALUE2 but the assign operator `=' is not allowed in Python expresion, so I can not call <dtml-call "x.attr2=VALUE2"> So I try: <dtml-call "x.__dict__.update({'attr2':'attrValue'})"> (the expresion in Python is (VERY) correct) When I try to save the DTML-METHOD , (NOT at the EXECUTION time), I get the error: ####### ... ... File /usr/lib/zope/lib/python/DocumentTemplate/DT_Util.py, line 357, in name_param (Info: ({'': '"x.__dict__.update({\'attr\':\'attrValue\'})"'}, 'call', 1, 'name')) File /usr/lib/zope/lib/python/DocumentTemplate/VSEval.py, line 175, in __init__ (Object: x.__dict__.update({'attr':'attrValue'})) TypeError: illegal name used in expression ... ##### I have take a look at VSEval.py, and looks like I can not use names that are starting with `_' and are not in ('_', '_vars', '_getattr') How can I add a new attribute to a variable? I can do this with an external method, but maybe exist other way... Thanks!

Customising the calling of the _add method for a product
by icottee＠bluefountain.com 10 Jul '00

10 Jul '00

I have a TimeSheet product which is currently utilising the suggestions from one of the howtos on zope.org, to make the handling of errors a little smarter. Subsequently my addForm code checks to see if any errors were detected and, if not, tries to go to the usual _add method. But this fails. The code below shows what I currently have. If I can just call this _add method I am finished. <dtml-if "I_Error==1"> <dtml-var TimeSheet_addForm_include> <dtml-else> <dtml-call "TimeSheet_add(_,_.None)"> </dtml-if> As always, any help greatfully received Ian

How to set Proxy-Roles
by Robert Wohlfahrt 10 Jul '00

10 Jul '00

Hi, i have a DTML-Method that adds a subfolder to a folder. I want to give anonymous users the permission, to add a Folder by using this DTML-Method. I added the Proxy-Role "Manager" to this DTML-Method, but anonymous users still can't use it - everytime they get a "You are not authorized to access manage_addFolder". Where is my mistake? Thanks Robert

Rendering Folderish ZClass Object
by Chris Withers 10 Jul '00

10 Jul '00

Hi, I have a ZClass based on Folder. Contained within this is a DTML Method, index_html. This is mapped to the 'View' view and renders the appropriate object contained in itself depending on soem logic. All, is well if I access the object through a URL, the page is rendered as expected. However, if I access the object with the following code: <dtml-var testObject> All I get is: <MyClass instance at 8717b90> Why is this? Why does the normal rendering not take place? cheers, Chris PS: I notice that a normal folder object will behave identically, so the ZClass bti is probably irrelevent.

Date-bug in properties?
by Peter Arvidsson 10 Jul '00

10 Jul '00

When I try to add a date-property and want to leave the Value-field empty i get the following error: Error Type: Invalid Date-Time String Error Value: When I write a date in the Value-field I can add the date. Is this a bug? Why cant I add a date with no default value? In several howtos they just add the date with no default value, so why cant I?
