How to validate node role with recipe

Hi Team,

I am trying to execute receipe which validate chef environment and role:
Recipe Example:

if (node.chef_environment == “dev” && node.role?(‘api’))

bash "Restarting service" do
  code <<-EOF
		#Codeblock
  EOF
end

end

if (node.chef_environment == “dev” && node.role?(‘web’))

bash "Restarting service" do
  code <<-EOF
		#Codeblock
  EOF
end

end

But while executing my code block is not working.

Why wouldn’t you simply start the service in all cases? Or set an attribute, in the role, that starts the service?

I don’t think that the name of the role used is an attribute the node knows about, unless you create one specifically in the role attributes.
