= [GenshiRecipes Genshi Recipes]: Replacing `py:extends` with Includes =
As noted in GenshiVsKid, Genshi does not support the `py:extends` directive for template reuse.
This page shows how the [http://www.kid-templating.org/language.html#template-reuse-py-extends example] from the Kid language specification translates to a functionally equivalent setup in Genshi.
Assume the following base template, stored as `base.html`:
{{{
#!genshi
}}}
And the following template “extending” that base template, stored as `page.html`:
{{{
#!genshi
Errors
The following errors were found:
${display_errors(["Field is required", "Must be phone number.."])}
}}}
The “trick” here is that the base template is included at the top of the page template. This results in the template function `display_errors()` being available to the page template, and the match template being applied to the output generated by the page template. If you write python code to directly run this example, be sure to use the TemplateLoader class to load `page.html`. If you use the MarkupTemplate class, XInclude processing is silently disabled.
When rendered, these will produce the following output:
{{{
#!text/html
Errors
The following errors were found:
- Field is required
- Must be phone number..
}}}
