The problem is that you can't call a macro directly from template in
pyramid. You need to add something like this in your python code
before rendering:
macros = get_renderer('mypackage:master.pt').implementation()
I would be cool if we can do something like:
<html metal:use-macro="mypackage:master.pt/macros/master" />
Don't know if this can be done easily... Maybe with a small python
helper added to template's context:
<html metal:use-macro="macros('mypackage:master.pt')['master']" />
Just a thought. Maybe the recommended way is to use a BeforeRender
event to add macros to context. But actually there is no recommended
way AFAIK :)
