ruby on rails - Iterate obect in view, JSON hash -


i have parsed json api externally , hash such: 

["statement", {"generated"=>"2015-01-11", "due"=>"2015-01-25", "period"=>{"from"=>"2015-01-26", "to"=>"2015-02-25"}}

i used: 

require 'json/pure' require 'open-uri'   def index    content = open("my_url").read    @hash = json.parse content    render @hash  end

and gives me whole hash output on view using:

<% @hash.each |hash| %> <%= hash %> <% end %>

so lets wanted print generated, due , period, separately, how this. i'm close know it.

array:

 ["statement", {"generated"=>"2015-01-11", "due"=>"2015-01-25", "period"=>{"from"=>"2015-01-26", "to"=>"2015-02-25"}}] ["total", 136.03] ["package", {"subscriptions"=>[{"type"=>"tv", "name"=>"variety movies", "cost"=>50.0}, {"type"=>"talk", "name"=>"talk anytime", "cost"=>5.0}, {"type"=>"broadband", "name"=>"fibre unlimited", "cost"=>16.4}], "total"=>71.4}] ["callcharges", {"calls"=>[{"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"07716393769", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}, {"called"=>"02074351359", "duration"=>"00:23:03", "cost"=>2.13}], "total"=>59.64}] ["store", {"rentals"=>[{"title"=>"50 shades of grey", "cost"=>4.99}], "buyandkeep"=>[{"title"=>"that's said", "cost"=>9.99}, {"title"=>"broke mountain", "cost"=>9.99}], "total"=>24.97}] [:prefixes, ["tasks", "application"]] [:template, "index"]

in nutshell, need extract values hash print them individually.

the first piece of code wrote array, not hash. first element of array string , second hash. first thing want create variable hash only, removing string:

<% @hash_values = @hash[1] %>

with hash, want extract values of 'generated', 'due' , 'period' looking them keys:

<%= @hash_values['generated'] %> <%= @hash_values['due'] %> <%= @hash_values['period'] %>

in case of 'period', result hash. many want extract individual values bit more formatting, e.g.:

<%= @hash_values['period']['from'] %> <%= @hash_values['period']['to'] %>

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
