[chef] Re: Re: application_ruby database block and attributes

THANK YOU!

I tried that, and since it worked, I went inside my definition and did

parameters = params

and voilà! parameters[:db][:username] works just as well! :)

Hi,

How do I pass parameters (preferably via attributes) to the database block in the application_ruby cookbook?

What I want to do is something like:

application “my_app” do

...

rails do

...

database do

username node[:my_app][:db_user]

password node[:my_app][:db_password]

end

end

end

It looks like the database block does not have access to the node object.

I have the application resource inside a definition, so I also tried to pass parameters to it, like params[:db_user], but that does not work either.

How do I set those database parameters dynamically?

Its an issue with Ruby's method lookup order. Outside of that block (I usually just do it at the top of the file) do "blah = node[:my_app]" and then in the block you can do "username blah[:db_user]" and whatnot since then it knows that blah is a variable and not a method call :-( method_missing, got to love it!
