外部Haml变量

Question

I created a layout with a variable inside.

layout.haml:

- title = "Example"
%title #{title}

It works perfect and gave me this:

<title>Example</title>

But, if I put this variable in a partial, it doesn't work

_vars.haml:

- title = "Example"

layout.haml:

=partial "vars"
%title #{title}

How can I define all the variables on an external document and make it work?

Thanks for the help

Answer 1

You are probably looking for content for:

layout.html.haml:

%title= yield(:title)

_my_partial.html.haml:

- content_for(:title) do
  Example

Answer 2

Maybe you could put your shared code in helper?

# application_helper.rb
def title
  @title ||= 'Example'
end

After that title helper could be used either in primary view or in partial. Notice that calculation of variable will be performed only once due to ||= .
