Access only one attribute of API in response - Ruby on Rails 4 -

i calling api returns array of json objects , can access return values of api call

[{"param1":1,"param2":"blah1"}, {"param1":2,"param2":"blah2"}, {"param1":3,"param2":"blah3"}] 

i know can access each param1 through iteration or static indexing @client[0].param1 @client[1].param1 @client[2].param1 thing , don't want param2 , want param1 . there way , access param1 without iteration or static indexing below result in response

[{"param1":1}, {"param1":2}, {"param1":3}] 

update

the thing notice want filter result while making request (before getting response when know attribute name)

try use delete.

deletes , returns key-value pair hsh key equal key. if key not found, returns default value. if optional code block given , key not found, pass in key , return result of block.

data = [{"param1":1,"param2":"blah1"}, {"param1":2,"param2":"blah2"}, {"param1":3,"param2":"blah3"}]  data.each {|x| x.delete("param2")} 

for more information delete. hope you.
