Hello,

I'm creating simple test recipe with a template and data bag. What I'm trying

to do is creating a config file from data bag that has simple nested

information, but I receive error "can't convert String into Integer" and I

can't find how to get data bag item "part.name"

Here are my setting files.

1) recipe/default.rb

data1 = data_bag_item( 'mytest', 'qa' )['test']

data2 = data_bag_item( 'mytest', 'qa' )

template "/opt/env/test.cfg" do

source "test.erb"

action :create_if_missing

mode 0664

owner "root"

group "root"

variables({

:pepe1 => data1['part.name'],

:pepe2 => data2['transport.tcp.ip2']

})

end

2)my data bag named "mytest"

test.json

{

"test":[

{

"part.name": "L12",

"transport.tcp.ip": "111.111.111.111",

"transport.tcp.port": "9199"

}

],

"transport.tcp.ip2": "222.222.222.222",

"id": "qa"

}

$knife data bag show mytest qa

id: qa

test:

part.name: L12

transport.tcp.ip: 111.111.111.111

transport.tcp.port: 9199

transport.tcp.ip2: 222.222.222.222

3)template file test.erb

part.name=<%= @pepe1 %>

transport.tcp.binding=<%= @pepe2 %>

Error returns when I run chef-client on my server,

I tried many things and if I comment out "pepe1 => data1['part.name'],", then

:pepe2 => data2['transport.tcp.ip2'] works fine. only nested data "part.name"

cannot be set to @pepe1.

Does anyone knows why I receive the errors?

thanks,

That type error is saying that you're accessing an Array as if it was a hash. Try pretty printing your `data1` variable like

    require 'pp'

    pp data1

That should show you the data structure. BTW, you can also use different formats with knife, e.g. knife TYPE show NAME -Fpp (for ruby pretty print) or -Fj (for json). The default format is optimized for readability at the expense of obscuring some details about the data.
