Which "methods" are you referring to?  The actual methods of the
template objects themselves?  If so, look at
Shared/DC/Scripts/Bindings.py (the Bindings base class defines __call__).

If i set the header as you said and manually refresh the page than it wont

Maybe I'm wrong but I think it should be something like :

  setHeader('Refresh', '5;URL=http://...')

Likely improper syntax. The correct syntax for the Refresh header is

Refresh: 5; url=http://foo.com

[Zope] redirect timeout doesn't work

[Dvir Bar-lev]

Hi

 

I want to redirect a user from my page to another page after a certain
time, I put this code in the dtml  page at the top I want to redirect
from:

 



 

But although it does refresh after the timeout it stays in the same page
instead of going to the address listed in URLAddress.

Anyone knows what I did wrong? Or I even did it the right way?

Unless you refresh after the form submit :-)

Of course if the broken design posted to a handler script instead of to
itself, a lot of problems could be side-stepped :-)

hi andreas:

the reason i need to do it this way is that no page template must be

This approach is broken by design-by-design. If you want to depend on

Re: [Zope] Order of method calls of ZopePageTemplate

i want to make sure that a certain method gets called before anything else
when the template gets rendered. so if i know about the order in which page
template methods get called, i can patch one (the first in the order).

Re: [Zope] session data object question

Name the submit button and check for the name of the button in the request.



"theButton" will appear in REQUEST (and REQUEST.form) if the button was
pressed.

[Zope] session data object question

[Dvir Bar-lev]

Hi 

 

I was wondering if there is a way to connect the creation of a session
object to a button push.

I'll explain in more detail:

 

I have a log in from called login_form, and I have a dtml method called
looged_in that is called when we push the submit button in the log in
form.

What I did is the following, in the log_in_form I get a session data
object only if it exsists and I check how much time passed and act
accordingly, in the looged_in method I create the data session oblject
ans set the start time.

Unfortuantly that is not good for me because if a user refreshes the
page it resets the time in the session object, I was wondering if there
is a way for me to know if I can reset the session data time only when
the user clicks the submit button and not as a result of a refresh call.

 

I tried looking on the web and in the zope book but I couldn't find
anything.

This question makes no sense. Template rendering (generation of HTML)
occurs on the *server*, form submission on the *browser*.
