jquery ajax call put data

Question

$.ajax({

type: "PUT",
url: url,
data: data,
dataType: 'json',
success: function(data) {
  alert("success");


},
error: function(data) {
  var errors = data.responseJSON;
  console.log(errors);
}

})
});

try to send response status with status: :unprocessable_entity when error occurs — Vishal

Your are sending errors with status code 200. Thats why jquery treats it as success. send validation errors with status code 400 or something — Aneesh R S

when validation fails you need to send response status with status: :unprocessable_entity so it will go in error event in ajax call

The required parameters in an Ajax error function are jqXHR, exception, use it like below :

  $.ajax({
    type: "PUT",
    url: url,
    data: data,
    dataType: 'json',
    success: function(data) {
        console.log(data);
    },
    error: function (jqXHR, exception) {
        console.log(jqXHR);
    }
  });
