Rails: как получить данные из params

You can access to the select key and over its value to split the content, getting the first one you have "key":

Code:

params = { "tweet"=>"", "select"=>"key=qwerty secret=qwerty token=qwerty token_secret=qwerty", "controller"=>"twitter_postings", "action"=>"index" } p params['select'].split.first # "key=qwerty"

You can also turn it into a hash if it's easier for you:

Code:

select_hash = params['select'].split.each_with_object(Hash.new(0)) do |element, hash| key, value = element.split('=') hash[key] = value end p select_hash['key'] # "qwerty

Hope this will helping you.

Code:

params = { "tweet"=>"", "select"=>"key=qwerty secret=qwerty token=qwerty token_secret=qwerty", "controller"=>"twitter_postings", "action"=>"index" }

for getting key value (qwerty) from this params following query will helping you.

Code:

params["select"].split.first.split("=").second # => "qwerty"

steps: 1

Code:

params["select"].split # => ["key=qwerty", "secret=qwerty", "token=qwerty", "token_secret=qwerty"]

steps: 2

Code:

params["select"].split.first.split("=") # => ["key", "qwerty"]

pick first value and split again with =

steps: 3

params["select"].split.first.split("=").second # => "qwerty"

finally pick the second value.
