Subject: [Zope] REQUEST.has_key does not find passed argument
Hello,
I'm new to Zope, Python and DTML and could therefore use some help.
I have a page in which I want to pass an argument to a new DTML method
when clicking a link. The relevant snippet is:
a href=/contact?name_id:int=dtml-var name_idContact/a
So, when you click on Contact you should get a new window. The variable
name_id is previously established on the page and shows up correctly
when the pointer hovers over the link, i.e. the status bar at the bottom
of the browser reads:
http://server.website.edu/contact?name_id:int=3
However, the DTML code for the new page doesn't seem to find this value
and returns a message telling me that no name was found. Because I am
stuck, here is the virtual entirety of the code:
dtml-if not REQUEST.has_key('name_id')
No name was found. Please specify a name.
dtml-else
Thank you! The request has been made.
/dtml-if
How can I get this page to recognize the passed argument so I can call a
method with it?
I have seen similar threads here on this topic but was unable to find a
solution from reading them. I am also baffled by the fact that in large
part I'm reusing the same code that seems to work perfectly in the same
format on other pages (which I didn't write). This is probably something
very simple, but I would really appreciate a hand.
Your code looked ok to me so I ran a quick test using two small dtml
methods:
dtml method 'tst':
dtml-var standard_html_header
br
dtml-let name_id=3
a href=tst2?name_id:int=dtml-var name_idclick here/a
/dtml-let
br
br
dtml-var standard_html_footer
dtml method 'tst2':
dtml-var standard_html_header
dtml-if not REQUEST.has_key('name_id')
No name was found. Please specify a name.
dtml-else
Thank you! The request has been made.
/dtml-if
dtml-var standard_html_footer
When you run tst and then click on the 'click here' link the message 'Thank
you! The request has been made.' appears. Therefore your code is working as
expected.
The only thing I can think of is that your dtml method called 'contact' is
not being invoked properly (do you have more than 1 contact method - perhaps
in different folders?). Also, try removing the '/' in front of the
'contact' in the href attribute of your html link.
