I create a JSON object in my html view using JSON.stringify(object) which outputs the following JSON object
{
"0X1W6": "{\"type\":\"Hourly\",\"hr\":\"12\",\"min\":\"30\",\"every_hr\":\"5\"}",
"Tk18f": "{\"type\":\"Daily\",\"hr\":\"12\",\"min\":\"30\",\"days_checked\":[1,4]}"
}
How do I convert this to a ruby object which would look something like this:
[
{ :type => 'Hourly', :hr => 12, :min => 30, :every_hr => 5}
{ :type => 'Daily', :hr => 12, :min => 30, :days_checked => [1,4]}
]
result = []
z = ActiveSupport::JSON.decode( '{
"0X1W6": "{\"type\":\"Hourly\",\"hr\":\"12\",\"min\":\"30\",\"every_hr\":\"5\"}",
"Tk18f": "{\"type\":\"Daily\",\"hr\":\"12\",\"min\":\"30\",\"days_checked\":[1,4]}"
}')
z.each_value do|i|
x = {}
ActiveSupport::JSON.decode(i).each{|k,v|
x[k.to_sym] = (v.class == String && v.to_i.to_s == v) ? v.to_i : v
}
result << x
end
{
"0X1W6": "{\"type\":\"Hourly\",\"hr\":\"12\",\"min\":\"30\",\"every_hr\":\"5\"}",
"Tk18f": "{\"type\":\"Daily\",\"hr\":\"12\",\"min\":\"30\",\"days_checked\":[1,4]}"
}.to_json
I'm assuming you are passing that JSON from JavaScript to your server. On the server, you can use the 'json' gem to parse JSON like so: o = JSON.parse json_string.
If you literally need the data structure combined (removing the keys 0X1W6 and Tk18f), you'll have to post-process your ruby hash into an array. Using the same technique, you can convert string keys into symbols.
When I understand correctly, you HAVE JSON and want a ruby hash. Within rails this can be done with ActiveSupport::Json.decode(json) while 'json' is a string. But this would not give you the exact results you are looking for, you would furthermore have to do:
ActiveSupport::Json.decode(json).values.symbolize_keys
I hope this helps.
