问题 I have a simple Spring Rest Controller with some validation. My understanding is that validation failures would throw a MethodArgumentNotValidException. However, my code throws a BindException instead. In debug messages, I also see the app returning a null ModelAndView. Why would a Rest Controller throw BindException or return a null ModelAndView? Note: I am testing my web application using curl and making an HTTP POST curl -X POST http://localhost:8080/tasks I am intentionally omitting the

问题 I have entity Market and Event . Market entity has a column: @ManyToOne(fetch = FetchType.EAGER) private Event event; Next I have a repository: public interface MarketRepository extends PagingAndSortingRepository<Market, Long> { } and a projection: @Projection(name="expanded", types={Market.class}) public interface ExpandedMarket { public String getName(); public Event getEvent(); } using REST query /api/markets?projection=expanded&sort=name,asc I get successfully the list of markets with

问题 I have some model with a timestamp field: models.py class Event(models.Model): event_type = models.CharField( max_length=100, choices=EVENT_TYPE_CHOICES, verbose_name=_("Event Type") ) event_model = models.CharField( max_length=100, choices=EVENT_MODEL_CHOICES, verbose_name=_("Event Model") ) timestamp = models.DateTimeField(auto_now=True, verbose_name=_("Timestamp")) I'm then using Django-rest-framework to create an API endpoint for this class, with django-filter providing a filtering

问题 I've been looking at examples of REST API's like Netflix http://developer.netflix.com/docs/REST_API_Reference#0_59705 and Twitter and they seem to place error messages in the statusText header response instead of the responseText. We're developing an internal RESTful api and I am arguing for sending custom statusText messages and ignoring the responseText. For the scope of our app, we're returning error 400 when the user has tried doing something they aren't supposed to, and the only error

问题 When you're writing a serializer, it is trivial to specify which fields will be included (via Meta 's fields ), setting read/write permissions on them and validating them. However, I was wondering if there is an easy way to specify that only the fields that are included are to be expected and any extra keys passed in should raise an error. E.g. say, I have a serializer class ModelASerializer(serializers.ModelSerializer): class Meta: model = models.ModelA fields = ('name', 'number') Supposed

问题 I use Jersey API for my REST service. My question is: Is there a more elegant way of returning exceptions in a JSON form? Is it better to concern myself with creating a json object myself and attaching it to the response directly? This is a simplified example of one of the methods in the service. As you see, I use HashMap only because the method may throw an exception, in which case I need to return information about It. @Path("/admin") public class AdminService { @Context HttpServletRequest
