The env is Solaris 10, facter 1.5.9, puppet 2.6.8, ruby 1.8.7 p302.
I''m trying to call the generate function inside of an erb template
and getting an error that the generate function doesn''t exist.
The following snippet from http://docs.puppetlabs.com/guides/templating.html
leads me to believe what I''m trying is doable and I''m most
likely
missing something obvious.
"Puppet functions can be called by prepending “function_” to the
beginning of the function name. For example, including one template
inside another:"
My testing was in a client server model but I''m able to reproduce it
with the following basic example. I''m wondering if anyone sees any
problem with how i''m calling the function from inside a template?
The manifest,template and generate script
gen.pp:
file { "/var/tmp/gen-test/genout":
content => template("/var/tmp/gen-test/templ.erb"),
}
templ.erb:
genvar=<%= scope.function_generate(["/var/tmp/gen-test/gencom"])
%>
gencom:
#!/usr/bin/env ruby -w
puts "raboof"
When the manifest is applied I get this
puppet apply gen.pp
Failed to parse template /var/tmp/gen-test/templ.erb: undefined method
`function_generate'' for #<Puppet::Parser::Scope:0x8e48ac4> at
/var/tmp/
gen-test/gen.pp:2 on node lil-derek
That error is the same as if I specify a function that obviously
doesn''t exist (burrito in this example)
which makes me think I''m not calling the generate function correctly.
Failed to parse template /var/tmp/gen-test/templ.erb: undefined method
`function_burrito'' for #<Puppet::Parser::Scope:0x8e48ac4> at
/var/tmp/
gen-test/gen.pp:2 on node lil-derek
I''ve been fussing with this for awhile now and would appreciate an
input.
TIA.

> It sounds like your running into Bug #4549:http://projects.puppetlabs.com/issues/4549 >Thanks for the tip. For a work around it looks like I can do the following in the template where generate is called (or any other function) <% Puppet::Parser::Functions.function(''generate'') -%> genvar=<%= scope.function_generate(["/var/tmp/gen-test/gencom"]) %> Or set a variable in the manifest via generate and then just refer to it in the template gen.pp: $var = generate(''/var/tmp/gen-test/gencom'') file { "/var/tmp/gen-test/genout": content => template("/var/tmp/gen-test/templ.erb"), } templ.erb: genvar=<%= var %>> There is a workaround given in the comments. > > -- > Peter M.
