As this is a Python expression that needs to be evaluated, it cannot be in a string. You can use the "%" operator which takes a format string and an object or tuple as parameters and formats object/tuple according to the string. If your Python method contains a "return result", then there is not magically a "result" variable (and there is not need for it, too). Are you sure, you want the nested "dtml-in". Looks very strange. Thus, you can use: dtml-in expr="REQUEST.form.items()" dtml-var expr="testSQL(text='%sx%s' % (_['sequence-key],_[' sequence-item]))" /dtml-in Dieter ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] renaming python input params in DTML
Hi, I am having a problem passing in a variable to a Python method, which is obtained from the REQUEST object - I'd really appreciate someone's insight into how to correctly go about this. I have a form that submits a parameter named '9728430xp0xclasstest' with a value = 7 to a DTML method. I have a Python method expecting 'text' as a parameter so I want the DTML method to send 'text' onto this with a value = the value of the original parameter appended to name (i.e. 9728430xp0xclasstestx7). So text=9728430xp0xclasstestx7 Does that make sense? The Python method, testSQL, returns 'result'. As I recently found out, I have to make to make use of the REQUEST object to obtain these parameters. The following snippet produces the correct value (9728430xp0xclasstestx7)... dtml-in expr="REQUEST.form.items()"dtml-var sequence-keyxdtml-var sequence-item/dtml-in ... but how can I can pass this as 'text' to my Python method? Am I on the right track with the following: dtml-in expr="REQUEST.form.items()" dtml-in expr="testSQL(text='dtml-var sequence-keyxdtml-var sequence-item')" dtml-var result /dtml-in/dtml-in Thank very much for any help you can offer. - Best regards, PS: dtml-let text="'9728430xp0xclasstestx7'" dtml-var text /dtml-let ... may help but... dtml-var standard_html_header dtml-in expr="REQUEST.form.items()" dtml-let text="'dtml-var sequence-keyxdtml-var sequence-item'" dtml-var text /dtml-let /dtml-in ... gives me text = x !

RE: [Zope] renaming python input params in DTML
You can't use DTML tags inside an expr="" attribute; the value of expr is python code. To access the sequence-item variable from python, you need: _['sequence-item'] So, try something like this (untested): dtml-in expr="REQUEST.form.items()" dtml-in expr="testSQL(text=_['sequence-key'] + 'x' + _['sequence-item'])" dtml-var result /dtml-in/dtml-in -Randy -Original Message- From: Lee [mailto:[EMAIL PROTECTED]] Sent: Sunday, January 14, 2001 1:23 PM To: [EMAIL PROTECTED] Subject: [Zope] renaming python input params in DTML Hi, I am having a problem passing in a variable to a Python method, which is obtained from the REQUEST object - I'd really appreciate someone's insight into how to correctly go about this.
