serializer

I am new to django. Can anybody help me... How can I upload a file using the Rest Framework API ? I have tried following this page: http://www.django-rest-framework.org/api-guide/parsers/#fileuploadparser File uploading in Django REST framework is the same with uploading files in multipart/form in django. To test it you can use curl: curl -X POST -H "Content-Type:multipart/form-data" -u {username}:{password} \ -F "{field_name}=@{filename};type=image/jpeg" http://{your api endpoint} Other fields are just like normal form fields in Django. Zhe answer is pretty well. Besides, you can add some

I have been working with XML in database LINQ and find that it is very difficult to work with the serializer. The database LINQ required a field that store XElement . I have a complex object with many customized structure class, so I would like to use the XmlSerializer to serialize the object. However, the serializer can only serialize to file ("C:\xxx\xxx.xml") or a memory stream. However to convert or serialize it to be a XElement so that I can store in the database using LINQ? And How to do the reverse? i.e. Deserialize an XElement... Try to use this using (var stream = new MemoryStream())

The text_with_headers serializer (HDFS sink serializer) allows to save the Flume event headers rather than discarding them. The output format consists of the headers, followed by a space, then the body payload. We would like to drop the body and retain the headers only. For the HBase sink, the "RegexHbaseEventSerializer" allows us to transform the events. But I am unable to find such a provision for the HDFS sink. You can set serializer property to header_and_text , which outputs both the headers and the body. For example: agent.sinks.my-hdfs-sink.type = hdfs agent.sinks.my-hdfs-sink.hdfs

I tried following this tutorial: http://javakart.blogspot.in/2012/12/spring-data-redis-hello-world-example.html My question is related to this: Weird redis key with spring data Jedis I was able to solve the keys and hashkeys using the StringRedisSerializer . <bean id="stringRedisSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer"/> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" p:connection-factory-ref="jedisConnectionFactory" p:keySerializer-ref="stringRedisSerializer" p:hashKeySerializer-ref="stringRedisSerializer" />

I have this two entities in my project class PoliceGroupe { /** * @var int * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @var string * * @ORM\Column(name="code", type="string", length=50) */ private $code; /** * @ORM\ManyToMany(targetEntity="PointVente", inversedBy="policegroupe") * @ORM\JoinTable(name="police_groupe_point_vente", * joinColumns={@ORM\JoinColumn(name="police_groupe_id", referencedColumnName="id")}, * inverseJoinColumns={@ORM\JoinColumn(name="point_vente_id", referencedColumnName="id")} * ) */ private

I have a case where the values for a serializer field depend on the identity of the currently logged in user. I have seen how to add the user to the context when initializing a serializer, but I am not sure how to do this when using a ViewSet, as you only supply the serializer class and not the actual serializer instance. Basically I would like to know how to go from: class myModelViewSet(ModelViewSet): queryset = myModel.objects.all() permission_classes = [DjangoModelPermissions] serializer_class = myModelSerializer to: class myModelSerializer(serializers.ModelSerializer): uploaded_by =

How can you include annotated results in a serialized QuerySet? data = serializer.serialize(Books.objects.filter(publisher__id=id).annotate(num_books=Count('related_books')), use_natural_keys=True) However the key/value pare {'num_books': number} is not include into the json result. I've been searching for similar questions on the internet, but i didn't found a solution that worked for me. Here is a similar case: http://python.6.x6.nabble.com/How-can-you-include-annotated-results-in-a-serialized-QuerySet-td67238.html Thanks! I did some research and found that serializer.serialize can only

I just ran into an error when I was using the Newtonsoft.Json SerializeObject method. It has been asked before here , but there was no answer from the people working with Newtonsoft as to why this happens. Basically, when calling SerializeObject like this: string json = Newtonsoft.Json.JsonConvert.SerializeObject(from, new JsonSerializerSettings() { TypeNameHandling = TypeNameHandling.All }); I get errors in a lot of Equals methods I have overridden in my classes: public override bool Equals(object obj) { if (obj == null) return false; CapacityConfiguration cc = (CapacityConfiguration)obj; //
