[Zope] RE: ZopeTime() and string.split/string.join

[Chris McDonough]

Nevermind.

Sorry...

The answer is to replace

<dtml-let tmp_time="ZopeTime()">

with

<dtml-let tmp_time="_.str(ZopeTime())">

This changes the object value into a string.

Ugh.

Subject: ZopeTime() and string.split/string.join


When I call this DTML method (in a container titled "News Items"):

<!--#var standard_html_header-->
<dtml-let tmp_time="title">
  <dtml-var "_.string.join(_.string.split(tmp_time,' '),'_')">
</dtml-let>
<!--#var standard_html_footer-->

I am returned the header, a line that says "News_Items", and the footer.

However, when I call this DTML method:

<!--#var standard_html_header-->
<dtml-let tmp_time="ZopeTime()">
  <dtml-var "_.string.join(_.string.split(tmp_time,' '),'_')">
</dtml-let>
<!--#var standard_html_footer-->

I get the following traceback:

Error Type: TypeError
Error Value: argument 1: expected read-only character buffer, instance found

Why is this?
