I am trying to pass an array of objects from js to rails
data.test = [{test: 'asdas'}]
$.ajax({
url: 'evaluate.json',
data: data,
success: function(data){
},
dataType : "json"
});
Rails
def evaluate
logger.info("#{params.test}")
end
Here the logger statement always gives me out put as
{"0"=>{"test"=>"asdas"}}
I am expecting the below log in rails.
[{:test=>"asdas"}]
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.
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"
});
