[Rest2web-develop] How to use custom macro in template files ?

[David C. <da...@ar...>]

Hi there,

    I am using rest2web for my own website, and it is working great, but 
I have one problem. I would like to use my own python functions in the 
templates, and I don't know how to do that. I manage to use my macro in 
a index file doing {print_hello}, but I cannot make it work in a 
template.txt (using <# print_hello() #>). I thought about adding it in 
the namespace using uservalues:

    [uservalues]
    foo = print_hello

But print_hello is transformer into a string before the template is 
processed. So how can I use my own python function in a template file ?

    Thanks,

    David

This should work. You should either import or define the function in the 
template. The function needs to print its output rather than simply 
return it (unless you use <% print_hello() %>).

Try something like:

<#
  def print_hello():
       print 'hello'
  print_hello()
#>

What do you mean by import ? The problem really seems to be related to 
being able to add my function in the "template's namespace".

This works without any problem. What I don't manage to get working is to 
define the print_hello in my macro file, and use it in the template: I 
have the print_hello in a macro file, the macro is set in my .ini file, 
I can use the function in index.txt, but in template.txt, I got a 
NameError: name 'print_hello' is not defined.


cheers,

David

Ok, the solution is so obvious I feel a bit embarassed... I just have to 
import the module where the macro are defined; it is just standard python.
