How to use different error codes for validation messages?


How to use different error codes for validation messages?

Hope that helps The default message is the message as stated by the programmer. In the case of those JSR-303 annotations probably the ones as Hibernate thought of them. The default message including the code is passed to the MessageSource.getMessage method, which contains a parameter defaultMessage
When you look at the Errors object or actually the ObjectError method you will see that it implements the MessageSourceResolvable interface. This means you can just pass the error, as is, to the MessageSource, including the Locale if you want.
code :
@RequestMapping
public Object foo(@Valid @RequestBody MyObject obj, Errors errors, Locale locale) {
    for (ObjectError err : errors.getAllErrors()) {
        String msg = messageSource.getMessage(err, locale);
        // Do something with msg
    }
}

I hope this helps you . You should beable to achieve this by creating your own HtmlHelper extension method.
E.g.
code :
public static string ValidationImage(this HtmlHelper htmlHelper, string modelName)
{
    if (modelName == null)
    {
        throw new ArgumentNullException("modelName");
    }

    if (!htmlHelper.ViewData.ModelState.ContainsKey(modelName))
    {
        return null;
    }

    ModelState modelState = htmlHelper.ViewData.ModelState[modelName];
    ModelErrorCollection modelErrors = (modelState == null) ? null : modelState.Errors;
    ModelError modelError = ((modelErrors == null) || (modelErrors.Count == 0)) ? null : modelErrors[0];

    if (modelError == null)
    {
        return null;
    }

    string messageText = GetUserErrorMessageOrDefault(htmlHelper.ViewContext.HttpContext, modelError, modelState);

    TagBuilder builder = new TagBuilder("img");
    builder.MergeAttribute("src", "urlToYourCrossImage");
    builder.MergeAttribute("class", HtmlHelper.ValidationMessageCssClassName); //Or your own custom class for the img tag here
    builder.MergeAttribute("alt", messageText);
    builder.MergeAttribute("title", messageText);

    return builder.ToString(TagRenderMode.SelfClosing);
}

With these it helps This question was posted quite a while ago, so I will add the updated answer here. Newer versions of DRF now support this, but it still takes a bit of custom code. Creating a new exception handler with do the trick:
code :
from rest_framework.views import exception_handler
from rest_framework.exceptions import APIException


def full_details_exception_handler(exc, context):
    """
    This overrides the default exception handler to
    include the human-readable message AND the error code
    so that clients can respond programmatically.
    """
    if isinstance(exc, APIException):
        exc.detail = exc.get_full_details()

    return exception_handler(exc, context)
REST_FRAMEWORK['EXCEPTION_HANDLER'] = 'my_module.full_details_exception_handler'

this one helps. You can't return a Response object from get_queryset to handle errors -- it must return a queryset (surprisingly).
But, you can raise an APIException and it will be wrapped in an appropriate response. You can look at APIException and its sublasses here.
code :
class IsFromSameLocation(permissions.BasePermission):
    message = 'You cannot view the posts of a user who is not from your location.'

    def has_permission(self, request, view):
        username = view.kwargs['username']
        user = User.objects.get(username=username)
        return user.userextended.location == \
                   request.user.userextended.location

#...

class PostListByUsername(generics.ListAPIView):
    serializer_class = SpillSerializer
    permission_classes = (IsAuthenticated, IsLikeOrOwnerDeleteOrReadOnly,\
                          IsFromSameLocation,)
