I am successfully done with pagination. but the problem I am facing is that "JSON response does not include information about total pages in my query and other information like total records etc". how can I include this information in my response. my view.py is from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger #######################View all mobiles @api_view(['GET']) def getAll_Mobiles(request): try:

问题 When I try to build/run a boost-Serialization example-code program, I'm getting errors, which I can't resolve and the code is from the boost serialization tutorial, so I don't think that it's wrong. I'm using the NetBeans 8.0.2 IDE and the Boost Library Version 1.58.0. The code: #include <fstream> // include headers that implement a archive in simple text format //#include <boost/archive/text_oarchive.hpp> //#include <boost/archive/text_iarchive.hpp> #include "../boost/archive/text_oarchive

问题 I like to using binaryformatter to serializing flow document. but it makes exception. [Serializable] public class BinFlow { public FlowDocument my { get; set; } } BinFlow myBF = new BinFlow(); myBF.my = myFlowDocument; FileStream myFile = File.Create(@"d:\test.bin"); BinaryFormatter myBinaryFormat = new BinaryFormatter(); //exception occured here!! myBinaryFormat.Serialize(myFile, myBF); Exception message said "FlowDocument does not decared 'Serializable' proeprty". ps. Of cause, I can use

问题 This question already has answers here : How to serialize Java 2D Shape objects as XML? (2 answers) Closed 6 years ago . I have a program that lets the user add rectangles and circles to JPanel using Graphics. What I want to be able to do is save the current state of the current JPanel (i.e. all of the shapes and their locations) into a file and be able to load that file back and restore that state. I have a Shapes class that extends JPanel and does all of the drawing and keeps track of the

问题 I try to use DataContractSerializer in my application in order to be backward and forward compatible and to support round trip (if possible). Is it possible to support round trip, or if not, is it possible to just ignore unknown types in the following scenario? Suppose I have a class ClassWithObject that has a property of type object and the older version of my application stored an object of type CurrentAdditionalData in this property. [DataContract] [KnownType(typeof(CurrentAdditionalData))

问题 In our Client/Server Application we've been using BinaryFormatter for the serialization process. For performance reasons we are trying to migrate to protobuf-net ( http://code.google.com/p/protobuf-net/ ). Our software transmits huge graphs with cycles between Client and Server. Now I am looking for a way to make sure that the data which was serialized and deserialized using protobuf is exactly the same as the one which was usually processed by BinaryFormatter. A bit by bit comparison is

问题 I have a dataset with multiple tables. I can obviously do a Dataset.WriteToXML("Somefile.xml") What if I want to export the dataset to a SQLite formatted file. In other words I want to be able to write (i.e. serialize) the contents of the dataset to a SQLite file. Dataset.SerializeToSQLite("Sqliteformatted.bin") Similarly I want to be able to read the SQLite file into a Dataset. I would like to do this in c#. Thanks in advance to any pointers. Bob 回答1: SQLite is not a file format, it's a
