Re: [Rails] JSON response , error message

in your controller:

render :json => { :errors => @example.errors.full_messages }, :status => 422

in your js file:

    $('.form_id_or_class').live('submit', function() {

      $.ajax({

        url: $(this).attr("action"),

          type: "POST",

          data: $(this).serialize(),

          success: function(data) {

           // do some action

        }

        ,error: function(xhr){

          var errors = $.parseJSON(xhr.responseText).errors

        }

      });

      return false;

    });

Hello

I am trying to show the errors that can occur by uploading a file (file

name, size).

I need have your error messages associated to the 'error' key in my json response

else

   format.html { render action: "new" }

   format.json { render json: @upload.errors, status:

:unprocessable_entity }

end

my validations:

validates_uniqueness_of :upload_file_name, :message => "File with

this name is already in the database"

validates :upload_file_size,  :inclusion  => {:in

=>10.megabytes..20.megabytes}, :message =>"Too big or too small"

      def to_jq_upload

        {

          "name" => read_attribute(:upload_file_name),

          "size" => read_attribute(:upload_file_size),

          "url" => upload.url(:original),

          "delete_url" => upload_path(self),

          "delete_type" => "DELETE"

        }

      end

    end

I have tried:
format.json { render json: => [{:error=> @upload.errors.full_messages }] } 

using this shows the validation message but I need the status: to be there as well

render json: {error: @upload.errors.full_messages}, status: :unprocessable_entity 

shows no error messages at all

  render json: {error: @upload.errors.full_messages}, status: :unprocessable_entity 
   I get an error-text : Internal Server Error and not what stands in my validation messages
  

Thanks in advanced
