Serialized Hash Rails

I've just started Rails dev and have a question about inputing data into a serialized hash in my database from a url with a variable number of params. I'm trying to figure out how to implement a url with any number of param/values in the form (action?1=.5&2=.6&3=.1 etc) that I want to add to my serialized hash. If my hash already has some key/values previously stored, how do I add more to the same hash? I want all the data to be in one column.

I have a method where I pass it a model object:

def add_data_to_hash(obj)
  params.each do |key, value|
    if (key.to_i.is_a?(Integer) && key.to_i != 0) then
      obj.hash[key] = value
      obj.save
    end
  end
end

Thanks!

Something like this maybe?

this should go on the controller

new_values = {}
url = request.fullpath.split("?").last
url.split("&").each do |kv|
  pair = kv.split("=")
  new_values[pair[0].to_i] = pair[1]
end
new_value.delete 0

and something like this inside your method

new_values.each do |k,v|
  object.hash[k] = v
end
object.save

Also it is better to call object.save once you finished updating the hash and not for every Integer key :)
