Hi RoR Developers

I got tiny problem here. Actually I asked before but there was not any
answer and asking again.

I have template.yml file.]
get_config=YAML.load(File.open("…/template.yml"))
$temp1path=get_config[“template”][“templatename1”]

I can get the values by using matrix one by one like above but how can I
list only right side I mean this is my template.yml file

template:
templatename1: template_of_roster.xml
templatename2: template_of_roster1.xml
templatename3: template_of_roster2.xml
templatename4: template_of_roster3.xml

only this column.
template_of_roster.xml
template_of_roster1.xml
template_of_roster2.xml
template_of_roster3.xml

thank you for any help or commend.

You’ll probably find that get_config.class == Hash
so you can get the values with:
get_config[“template”].values
which gives you an Array over which you could iterate with .each

I wrote something like this
require ‘yaml’
get_config=YAML.load(File.open(“C:/yotta/config/template.yml”))
get_config.class == Hash
get_config[“template”].values
get_config.each do |k,v|
puts v.inspect
end

result
{“templatename1”=>“template_of_roster.xml”,
“templatename2”=>“template_of_roster1.xml”,
“templatename3”=>“template_of_roster2.xml”, “templatename4”=
“template_of_roster3.xml”}

why I can not get only second column. I only want this side.
template_of_roster.xml
template_of_roster1.xml
template_of_roster2.xml
template_of_roster3.xml

how should I change my codes.
thank you very much for your help Rob B. …

This is a boolean expression, it doesn’t do anything to the
get_config object

get_config.class == Hash

You should save this in a variable

get_config[“template”].values
get_config.each do |k,v|
puts v.inspect
end

or just do:
puts get_config[“template”].values

template_of_roster2.xml
template_of_roster3.xml

You’re really not having issues with Rails, but with plain old Ruby
(and YAML from the standard library, of course).

hmm
how can I convert to string I mean I know to_s but how will I use it
here. I want to assign the values to variable.
I have selection which is taken these values.

<%
templateOptions = “”
@templates.each do |i|
templateOptions = templateOptions + “#{i}”
end
%>
<%=select_tag “templates”, templateOptions %>

thank you very much again…

<%= select_tag “templates”,
options_for_select(get_config[“template”].values) %>

Even if you were to build it yourself, you might find Enumerable#map
(aka, Enumerable#collect) and Array#join useful:

templateOptions = @templates.map {|t| %{#{t}</
option>} }.join

These particular strings aren’t likely to pose a problem, but you
should also know about ERB::Util#html_escape (often seen in views as
just h)
