Custom LWRP undefined local variable or method `new_resource'

bbaugher · January 4, 2012, 5:45pm

I created a custom resource that tries to mimic ruby_block’s block. This
resource was for Rspec and I wanted to follow the typical style of writing
rspec with the format,

rspec “myApp” do
it “should …” do
…
end
end

So I have written my resource as follows,

//

def initialize(*args)
super
@action = :describe
end

def it(s, &it)
if s
should(s)
end

if block_given? and it
@it = it
else
@it
end
end

actions :describe

attribute :name, :kind_of => String, :name_attribute => true
attribute :should, :kind_of => String, :default => “RSpec Test”

\

And my provider as,

//

action :describe do
run_context.include_recipe “rspec”

ruby_block “Rspec:#{new_resource.name}” do
block do
require ‘rspec/autorun’

  describe new_resource.name do
it new_resource.should do
  new_resource.it.call
end
  end 
end

end

new_resource.updated_by_last_action(true)
end

\

Chef is telling me that new_resource is undefined in my provider at,

‘it new_resource.should do’

Any thoughts?

Using @new_resource gives me a 'undefined method `name' for nil:NilClass'
at 'describe @new_resource.name do'. I don't think the ruby_block likes the
@new_resource.

Probably RSpec is changing the execution context. Throw a puts self.inspect in there to see.

Yes, you are right. 'puts self.inspect' gives '#Class:0x2b2aba647728'
inside the describe block, where as outside 'put self.inspect' gives a
large blob of chef info.

I am still pretty new to ruby, is there a way to pass new_resource into
this block?

Why use a ruby block in your action? The action code already executes in the converge phase. You could try to use ruby's ' eval' method directly to call into rspec

I am using a ruby_block because I don't want the rspec require or testing
to occur before the 'run_context.include_recipe "rspec"' as that will
ensure that rspec is installed.

That helped me get pointed in the right direction, but didn't quite work
for me since I could not turn my proc into ruby code.

I found doing this works almost works,

block = new_resource.it
should = new_resource.should

describe new_resource.name do
it should do
Rspec.class_exec{ block.call }
end
end

But the block still doesn't know about Rspec, giving a 'undefined method
exception for raise_error' a Rspec method.

inside the describe block, where as outside 'put self.inspect' gives a
large blob of chef info.

I am still pretty new to ruby, is there a way to pass new_resource into
this block?

ruby_block "Rspec:#{new_resource.name (http://new_resource.name)}" do

new_resource.updated_by_last_action(true)
end

Chef is telling me that new_resource is undefined in my provider at,

'it new_resource.should do'

Any thoughts?

Probably RSpec is changing the execution context. Throw a puts self.inspect in there to see.

Have a look at this, sounds like you are re-implementing some of the
stuff that I did for the MiniTest cookbook:

https://github.com/fujin/minitest-cookbook/blob/develop/cookbooks/minitest/providers/unit_testcase.rb#L38-48

Cheers,

I am using a ruby_block because I don't want the rspec require or testing to
occur before the 'run_context.include_recipe "rspec"' as that will ensure
that rspec is installed.

That helped me get pointed in the right direction, but didn't quite work for
me since I could not turn my proc into ruby code.

I found doing this works almost works,

block = new_resource.it
should = new_resource.should

describe new_resource.name do
it should do
Rspec.class_exec{ block.call }
end
end

But the block still doesn't know about Rspec, giving a 'undefined method
exception for raise_error' a Rspec method.

Why use a ruby block in your action? The action code already executes in
the converge phase. You could try to use ruby's ' eval' method directly to
call into rspec
