I´m not able to completely integrate an Angular front-end with a Rails back-end API. They both run in differente servers, so I think I have problems with CORS.
My Angular app is running a controller that is calling a service that has resource with a query (GET) and save (POST) methods. The query (GET) is working fine, however the post is not working.
I´m able to send a POST request to the server when I don´t send any parameter. Like this:
Controller:
$scope.createBusiness = function() {
console.log("Business.name=" + $scope.business.name);
$scope.business = Business.save();
};
Service:
.factory('Business',
function($resource){
var businesses =
$resource('http://127.0.0.1\\:3000/:business', {business:'businesses'}, {
query: {method:'GET', isArray: true},
save: {method:'POST', isArray: false}
});
return businesses;
}
);
However, I want to post my model parameters, so when I try to send something then I don´t send a POST request anymore, but an OPTIONS request. And I get an error.
Please, see my request data when I send a request without parameters (POST request):

I reach the server, execute the method and get the response! This is ok.

UPDATE
I forgot to add my controller when adding a model parameter:
$scope.createBusiness = function() {
console.log("Business.name=" + $scope.business.name);
$scope.business = Business.save($scope.business);
};
I have several views, with several forms, so, I don´t want only to post a form, but the business object model that I have in scope (and I filled with the data of all the forms).
UPDATE
This is my Rails Application_Controller (CORS configuration):
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
# OJOJOOJO: Rober: I have commented this line which is provided by default with rails and added all code below in order to
# add CSRF protection
#protect_from_forgery with: :exception
protect_from_forgery
before_filter :cors_preflight_check
after_filter :cors_set_access_control_headers, :set_csrf_cookie_for_ng
# For all responses in this controller, return the CORS access control headers.
def cors_set_access_control_headers
headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
headers['Access-Control-Request-Method'] = '*'
headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'
headers['Access-Control-Max-Age'] = "1728000"
end
# If this is a preflight OPTIONS request, then short-circuit the
# request, return only the necessary headers and return an empty
# text/plain.
def cors_preflight_check
if request.method == :options
headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
headers['Access-Control-Request-Method'] = '*'
headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'
headers['Access-Control-Max-Age'] = '1728000'
render :text => '', :content_type => 'text/plain'
end
end
def set_csrf_cookie_for_ng
cookies['XSRF-TOKEN'] = form_authenticity_token if protect_against_forgery?
end
protected
def verified_request?
super || form_authenticity_token == request.headers['X_XSRF_TOKEN']
end
end
