Passing parameters to base layout not working

[Dexter]

Hi

I am currently using  a base template like

render = web.template.render('templates/', base='layout')

I would like to pass some arguments to layout.htm
I know this can be done as (http://webpy.org/cookbook/layout_template)

templates/index.htm

---------------------------------------
$var title: This is title.

<h3>Hello, world</h3>
---------------------------------------

and access content.title in the layout page


My problem is I am trying to pass a form Dropdown object to index.htm and want that to be rendered in layout.htm

I am not able to get it right can anyone plz help with the syntax

My code

templates/index.htm

---------------------------------------------
$def with (data)
$var title: Overview

<br />
	
$var dropdown: $:data.dropdown

---------------------------------------------

templates/layout.htm

---------------------------------------------
$def with (content=None,)

	$content.dropdown.render()
---------------------------------------------

And this does not work

Try this:

$var dropdown = data.dropdown

Worked like a charm ... so was supposed to use = instead of :

Does : pass a string and = a python object ?

Also, is it possible to send parameter directly to the base layout ?

[Andrey Kuzmin]

Only if you init render without base and access layout directly like this: render.layout(render.page(**page_args), **layout_args)

Another option would be enabling access to web.ctx in templates by passing it in template globals and then set ctx properties in your controller methods.

This second method sounds good ... So is it only globals that the template can have access to ?
Cant I access session parameters ?

like set the option in session.options and access it inside template. I know I can check this instead of asking ... just wanted to know if this is a preferred method of doing thing ?

Yes you can pass session to template globals and use it in templates. 

But everything stored in session will be saved between requests.

If you need it only during particular request then you should store data in web.ctx.

Thanks ... that helps

Is it unpythonic or unwepyish if I set a variable I need in base layout in template_globals and pass it like this
        fullrender = web.template.render('templates/',base='menu',globals=template_globals)

Depends on the context of fullrender, if you create in only once in your application, then its ok.

But if you want to do this in every request, then I think it is a bad idea.
