Forum: Ruby on Rails Writing data into yml file in a particular format

Hi,

I have a hash in a controller file which I have to write into a YAML.yml
file in a particular format.

This is the code I am using in the controller to write to yml file.

"File.open("config/locales/output.yml", "w") {|f|
f.write(hash_data.to_yaml) }"

output.yml is the yml file.
hash_data is my hash which has a key having a hash to array of values.

Current output;
---
'01':
- red
- green


Expected output:
en:
  01: "red, green"


Is this possible?

Regards,
Nikhil

You could convert your array to a string before to call .to_yaml: [ 
'red',
'green' ].join(', ')

It's certainly possible, but if you want the output YAML to look like 
that
you're going to need to put the *input* data into the same sort of 
format.
 For instance, running the expected output (with quotes around 01, to 
avoid
it being parsed as an integer) through YAML.load gives this Ruby result:

{"en"=>{"01"=>"red, green"}}
