I need to create a method that should return yaml in the following
format
---
- name: device-1
parameters:
app_folder: deploy_project
app_id: "1"
tar_file: deploy_project.tar.gz
profile_id: "3"
version_id: "2"
classes:
- install
I have all these values (device-1, deploye-project etc) captured into a
variable "result" that are coming from the database but i just need to
return them in the above format as a yaml using
puts yaml_obj = result.to_yaml

Is the result a Rails model? If so, easy, just build a string and insert
your variables into the string. You can do this in a model method like so:
def to_yaml
yaml = "---"
yaml += "- name: #{self.device_name or wherever you store this}"
blah blah
so on
return yaml
end

For the first (and only element) of the array, there is a Hash with three keys: 1.9.3-head :006 > isit.first.keys => ["name", "parameters", "classes"] The first one is trivial: isit.first[''name''] => ''device-1'' The second key is a Hash of your parameters: isit.first[''parameters''] => {"app_folder"=>"deploy_project", "app_id"=>"1", "tar_file"=>"deploy_project.tar.gz", "profile_id"=>"3", "version_id"=>"2"} And the third is an array, again because your item underneath classes begins with a ''-'': isit.first[''classes''] => ["install"] So the data structure you want to construct looks like: [{''name'' => ''device-1'', ''parameters'' => {''app_folder'' => ''deploy_project'', ''app_id'' => ''1'', ''tar_file'' => ''deploy_project.tar.gz'', ''profile_id'' => ''1'', ''version_id'' => ''2''}, ''classes'' => [''install''] } ] and chaining that to .to_yaml will create the YAML you want. Converting your input to that structure is still up to you. Not knowing anything about where you are getting the input, it''s hard to advise. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
