serialization

问题 Symfony serializer lost collection object while denormalizing. Example: We have some entity with collection in the property (I'm using Doctrine ArrayCollection but it is reproduced for any Collection which implement PHP Iterator interface) Let's serialize and deserialize it with Symfony and JMS serializer and compare results: Origin: ^ App\Entity\Entity^ {#195 -rewardItems: Doctrine\Common\Collections\ArrayCollection^ {#179 -elements: array:2 [ 0 => App\Entity\Item^ {#224 -type: 1 } 1 => App

问题 Almost the same question but the accepted answer does not fit the general need. Having Simple class and custom serializer like: Example class @Getter @Setter public class ExampleClass { @JsonInclude(JsonInclude.Include.NON_NULL) @JsonSerialize(using = StringSerializer.class) private String stringNull; @JsonInclude(JsonInclude.Include.NON_NULL) @JsonSerialize(using = StringSerializer.class) private String stringOk = "ok"; @JsonInclude(JsonInclude.Include.NON_NULL) @JsonSerialize(converter =

问题 I'm trying to serialize ClassA into JSON and then deserialize and map it into ClassB only on similar attribute, ignoring a lot of checking. Lets say I have public class First{ private String attribute1; private String attribute2; private String attribute3; } public class Second{ private Int attribute1; private String attribute2; private String attribute4; } What am I expecting is mapping an object of Second like { "attribute2": "value2" } Is it possible? I need to do this because I have a

问题 Before writing this question, I tried this, this and this method. I spent the whole day on it and could not get the result. I have my own REST API which returns a serialized List<T> in XML file [ActionName("planes")] [HttpGet] public IEnumerable<Planes> GetPlanes() { using (DB_A5vehiclesEntities entities = new DB_A5_vehiclesEntities()) { return entities.Planes.ToList(); } } Generated XML file looks like this (link to xml file): <ArrayOfPlanes xmlns:i="http://www.w3.org/2001/XMLSchema-instance

问题 I have the following IValueFormatter : public class NLogValueFormatter : IValueFormatter { public bool FormatValue(object value, string format, CaptureType captureType, IFormatProvider formatProvider, StringBuilder builder) { if (value.GetType() == typeof(LogData)) return false; builder.Append(format); try { var myTarget = LogManager.Configuration.FindTargetByName("communicationFileLog"); myTarget = ((myTarget as NLog.Targets.Wrappers.WrapperTargetBase)?.WrappedTarget) ?? myTarget; var

问题 I'm trying to do a search on serialized post meta values in a wordpress database. I know the structure of the serial string so I can search for the preceding value, get the index and then get the number of characters I want before that index value. I cannot effectively use regexp in this particular query because I would like to sort based on the results. This is what I have so far, but I am failing on the syntax and I think it has to do with trying to use the AS keyword and my grouping the

问题 We have a legacy system that needs to be fed (XML) data in a most unstructured format. Is the following even possible with the .NET DataContractSerializer ? Given the following DataContracts [CollectionDataContract(Name = "Options", ItemName = "Option")] public class OptionItemCollection : List<OptionItem> { [DataMember(Name = "Name")] public string Name { get; set; } public OptionItemCollection() { } public OptionItemCollection(IEnumerable<OptionItem> items) : base(items) { } } [DataContract

问题 I have a question regarding POST request with nested objects in Django with serializers: I have checked this: Stackoverflow 1 Django Doc Stackoverflow 2 I've created some serializers in my Django project following the architecture below: EP_project │ │ └───ep_python │ db.sqlite3 │ manage.py │ __init__.py │ ├───ep │ │ admin.py │ │ apps.py │ │ models.py │ │ tests.py │ │ urls.py │ │ __init__.py │ │ │ ├───migrations │ │ │ ├───models │ │ │ model_aa.py │ │ │ model_ap.py │ │ │ model_apr.py │ │ │
