Hi group,

Basic concept is that any template accepts any variable you define in
the ``$def with`` line. That includes templates, naturally. For any
template, you can also define attributes with ``$var`` line. So, if
you have this in xyz:

$var title: My tempalte's title

and this in base:

$def with (child_template)

You can pass the child template as a variable to base template:

render.base(render.xyz())

and in base you can:

$:child_template

or:

<title>$child_template.title</title>

It's actually quite flexible, as you can see.

Templates really like python functions.

If you want to support something like layout template, then you need
to do like this:

render.layout(render.page(page))

Thanks a lot guys, i really appreciate your time in explaining the concept.

Thank you

Another way is to define render function in the template globals, like
this:

template_globals = {}
render_partial = web.template.render(rootdir+'/templates/',
globals=template_globals)
render = web.template.render(rootdir+'/templates/',
globals=template_globals, base='layout')
template_globals.update(render=render_partial)


Then you will be able to call $:render.any_template() in templates.

So, in base.html, if i had:

$def with (var1, var2, render.xyz())

it will globally render against any template that is evaluated in the base.html (called from the render in code)?

If so, it would be curious to know if variables for pagination, current link, other base-type functions could be passed in.

i'll play with the first part first :)

You can't have a method call there. You could pass render.xyz() to
base, which is what I described in my reply.

I don't understand the concept of 'global rendering', but the template
instance will act just like any other variable you care passing to the
template.

It's like arguments for a function, really. If you know what x, y, and
z mean in:

def myfunc(x, y, z):
pass

then you can apply the same to Templetor templates.
