[chef] Re: Re: Re: Re: Re: Custom LWRP undefined local variable or method `new_resource'

[Bryan Baugher < >]

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

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?

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