Problems parsing parameters from Angular post in Rails controller

Question

I have an Angular.js app that sends a POST request to a Rails server endpoint and I'm having trouble passing and reading the parameters.

This is how I send the data

$scope.submitForm = function(info) { $http({ method: 'POST', url: app.apiServerUrl + '/complaints/create', data: info, headers: {'Content-Type': 'application/x-www-form-urlencoded'} }).success(function(data, status, headers, config) { // this callback will be called asynchronously // when the response is available }).error(function(data, status, headers, config) { // called asynchronously if an error occurs // or server returns response with an error status. }); };

The info object passed is a object in the form: { title: "something", ocurrence_place: "something" }.

And in my controller create action I have this:

def create p params p params[:title] end

but this is what gets printed in the logs

{"{\"title\":\"foo\",\"ocurrence_place\":\"bar\"}"=>nil, "controller"=>"complaints", "action"=>"create"} nil

So, as you can see, I can't access params hash attributes. How can I fix this so the controller in my controllers works and prints what is expected?

It looks to me like your info object isn't really an object but a string of JSON.

Try changing data: info to data: JSON.parse(info) or correcting whatever is calling submitForm(info) so that the info argument is really a object.

thanks, I ended up actually using JSON.stringify, but you gave me the first idea :D

I believe the fix is to change data: info, into data: JSON.stringify(info),
