Template Notes
Fastfood uses the Jinja2 templating
engine with
2 modifications.
qstring()
There is a helper method added to jinja2 for fastfood called qstring,
it
takes in an argument and if that argument does not match a Chef node
attributes (node[‘mysomething’] | node.chef_environment) it will
wrap that argument
in a string otherwise it just returns the argument.
qstring("node['mysomething']")
renders as
node['mysomething']and
qstring("mynonchefstr")
renders as
"mynonchefstr"
jinja variable
Because the traditional jinja2 variable start and end strings can
conflict
with Ruby code fastfood uses ‘|{’ and ‘}|’ to represent a jinja2
variable.
