input = {:a=>{:type=>"list", :values=>[{:type=>"b", :id=>"123"}, {:type=>"b", :id=>"456"}]}}
output should be as follows
{:new_name=>"123,456"}
I tried using inject like this.Not sure what to include inside the block
input.tap do |e|
e[:a].try(:[], :values).inject({}) do |h, obj|
h[:new_name] = **
end
end
You are given:
input = {:a=>{:type=>"list",
:values=>[{:type=>"b", :id=>"123"},
{:type=>"b", :id=>"456"}
]
}
}
Let's first simplify:
a = input[:a][:values]
#=> [{:type=>"b", :id=>"123"},
{:type=>"b", :id=>"456"}]
Now pull out the strings we need:
b = a.map { |h| h[:id] }
#=> ["123", "456"]
Lastly,
{ "new_name" => b.join(',') }
#=> {"new_name"=>"123,456"}
Putting this all together,
{ "new_name" => input[:a][:values].map { |h| h[:id] }.join(',') }
#=> {"new_name"=>"123,456"}
{:new_name => input.values.first[:values].map{|hash| hash[:id]}.join(',')}
# => {:new_name=>"123,456"}
This works only if your input hash has always the same structure.
