passing array of objects from js to rails

Question

I am trying to pass an array of objects from js to rails

data.test = [{test: \'asdas\'}]

$.ajax({
  url: \'evaluate.json\',
  data: data,
  success: functio         


        

Answer 1

You should use JSON.stringify in Javascript, which takes either an array or hash as its argument (since these are the only valid JSON constructions). It returns a form which is the Javascript object serialized to JSON.

On the Ruby side, you'll receive a JSON encoded string, so you'll need to require 'json' (this is done automatically in Rails) and use JSON.parse(string). This will give you a Ruby object.

Answer 2

Try this:

data.test = [{test: 'asdas'}]

$.ajax({
  url: 'evaluate.json',
  data: JSON.stringify(data),  // Explicit JSON serialization
  contentType: 'application/json',  // Overwrite the default content type: application/x-www-form-urlencoded
  success: function(data){
  },
  dataType : "json"
});
