Hi,

I try to create a receipt which updates a configuration file in the deployed apps and, if the configuration was changed clears the caches folders of the app.

I found some code at http://wiki.opscode.com/display/chef/Resources#Resources-Notifications

template "/etc/nagios3/configures-nagios.conf" do
  # other parameters
  notifies :run, "execute[test-nagios-config]", :immediately
end

# this will fail and prevent us from restarting nagios if we broke the config
execute "test-nagios-config" do
  command "nagios3 --verify-config"
  action :nothing
end

This is my code:

node[:deploy].each do |application, deploy|

  template "#{deploy[:deploy_to]}/current/app/config/parameters.ini" do
    source "parameters.ini.erb"
    mode "0660"
    group deploy[:group]
    owner deploy[:user]
    variables(:database => deploy[:database])

    only_if do
      File.directory?("#{deploy[:deploy_to]}/current/app/config")
    end

    notifies :run, "execute[clear_cache]"

  end

  execute "clear_cache" do
    command "rm -rf  #{deploy[:deploy_to]}/current/app/cache/*"
    action :nothing
  end

end

and the error is:

DEBUG: Re-raising exception: NoMethodError - undefined method `run_action' for "execute[clear_cache]":String

Sorry, I've not done much with ruby, yet :)
Thanks for your help.

   Can you try

   notifies :run, resources(:execute => "clear_cache")
   

   instead of

   notifies :run, "execute[clear_cache]"
   

   Also, I would make sure, that the resource is unique per app, e.g:

   node[:deploy].each do |application, deploy|
   
     template "#{deploy[:deploy_to]}/current/app/config/parameters.ini" do
       source "parameters.ini.erb"
       mode "0660"
       group deploy[:group]
       owner deploy[:user]
       variables(:database => deploy[:database])
   
       only_if do
         File.directory?("#{deploy[:deploy_to]}/current/app/config")
       end
   
       notifies :run, resources(:execute => "clear_cache_#{application}")
   
     end
   
     execute "clear_cache_#{application}" do
       command "rm -rf  #{deploy[:deploy_to]}/current/app/cache/*"
       action :nothing
     end
   
   end

   Ok .. it failed now because it won't find the execute action but after I put the execute block above the template block it works now.

   Thanks for your help and the hint with the unique identifier.
