I am trying to create a model that has various timestamps (createdAt, updatedAt, deletedAt), with default values. How can this be achieved? I tried playing around with the prepare method, but to no avail. Thank you in advance.
This is my current class:
Vapor offers sth like:
static func prepare(on connection: MySQLConnection) -> Future<Void> {
return Database.create(self, on: connection) { builder in
builder.field(for: \.iq, type: .int, .default(.literal("123456")))
...
this should work with Dates as well.
Or you could try to set them in a custom init:
required init(id:Int?, adressLine1:String, adressLine2:String?, city:String, state:String, zip:String) {
self.id = id
self.adressLine1 = adressLine1
self.adressLine2 = adressLine2
self.city:String = city:String
self.state = state
self.zip = zip
self.createdAt = Date() //<---- here
self.updatedAt = Date() //<---- here
self.deletedAt = Date() //<---- here
}
or:
required init(id:Int?, adressLine1:String, adressLine2:String?, city:String, state:String, zip:String,
createdAt:Date = Date()/*<--- here*/, updatedAt:Date = Date()/*<--- here*/,deletedAt:Date = Date()/*<--- here*/) {
self.id = id
self.adressLine1 = adressLine1
self.adressLine2 = adressLine2
self.city:String = city:String
self.state = state
self.zip = zip
self.createdAt = createdAt
self.updatedAt = updatedAt
self.deletedAt = deletedAt
}

The 3rd item, salesGst[2], is "PartyGST": null. Your json deserializer library won't handle non-null fields as it's written in Java. I assume you have a data class where PartGST is defined as non-null, yet the deserializer will still parse it as null. Therefore, when you access PartyGST then you will receive a NullPointerException because Kotlin is expecting it to be non-null. This is a good article, which explains in more detail:
I've trusted you! You promised no null pointer exceptions!
A solution to this would be to have two models. The DTO (for JSON response) where all fields are optional and your internal model (used by your app), where you define which fields you want to be optional. Then you can have a mapper to handle the case where a field is null in the DTO, but non-null in your internal model:
// Models for your API response
data class SalesGstsDTO(val gsts: List<GstDTO>)
data class GstDTO(val name: String?, val surname: String?)
// Internal models used by your app
data class SalesGsts(val gsts: List<Gst>)
data class Gst(val name: String, val surname: String?)
class SalesGstDTOMapper {
fun mapToSalesGsts(salesGstsDTO: SalesGstsDTO): SalesGsts {
val gsts = mutableListOf<Gst>()
salesGstsDTO.gsts.map {
val name = it.name ?: return#map // Skips this item. You could handle this how you wish
val surname = it.surname
val gst = Gst(name, surname)
gsts.add(gst)
}
return SalesGsts(gsts)
}
}
This also allows you to decouple your app from the JSON response.
I'm trying to add to the JsonResult object a parsed Json string, but I couldn't do it, the parser object in the browser is shown as:
"filter":[[[]],[[[],[]]]]
This is the full code
public JsonResult AjaxStandardGet(int id)
{
Standard ec = db.Standard.FirstOrDefault(s => s.IdStandard == id);
// inside filter: { "KeyDynamic1": "Value1", "KeyDynamic2": [ "AAA", "DDD"] }
var filter = JsonConvert.DeserializeObject(ec.Filter);
return Json(new
{
ec.IdStandard,
ec.Description,
filter,
ec.Observations,
Services = ec.StandardServices.Select(s => new {
s.IdStandardServices,
Tecnology = s.Tecnology?.Nombre,
ServiceType = s.ServiceType?.Description,
s.Quantity,
s.Cost,
Options = (!string.IsNullOrEmpty(s.Options) ? s.Options.Split(',') : null),
Total = s.Quantity * s.Cost
}),
Success = true
});
}
I can't create the model object because the filters are not allways the same.
I tried this:
Dictionary<string, object> filter = JsonConvert.DeserializeObject<Dictionary<string, object>>(ec.Filter);
And I get
"filter":{"KeyDynamic1":"Value1","KeyDynamic2":[[],[]]}
I suggest you to JToken or dynamic:
JToken filter = JToken.Parse(ec.Filter);
dynamic filter = JsonConvert.DeserializeObject<dynamic>(ec.Filter);
Here is working fiddle.
Update
It seems that JavaScriptSerializer is not able to do it. So you can serialize your result using Newtonsoft.Json and return it as a string:
var result = new
{
ec.IdStandard,
ec.Description,
filter,
ec.Observations,
Services = ec.StandardServices.Select(s => new {
s.IdStandardServices,
Tecnology = s.Tecnology?.Nombre,
ServiceType = s.ServiceType?.Description,
s.Quantity,
s.Cost,
Options = (!string.IsNullOrEmpty(s.Options) ? s.Options.Split(',') : null),
Total = s.Quantity * s.Cost
}),
Success = true
};
var json = JsonConvert.SerializeObject(result);
return Content(json, "application/json");
I am developing a ASP.NET MVC Web Api. Project. I am returning data with JSON format. Before I return data to user I serialize data using JsonConvert.SerializeObject to change their json property names.My code return data in JSON format. But with an issue. That is it always return data into string even if the data is array or object.
This is my action method that returns json.
public HttpResponseMessage Get()
{
IEnumerable<Region> dbRegions = regionRepo.GetCachedRegions();
List<ContentRegion> regions = new List<ContentRegion>();
if(dbRegions!=null && dbRegions.Count()>0)
{
foreach(var region in dbRegions)
{
ContentRegion contentRegion = new ContentRegion
{
Id = region.Id,
ImageUrl = Url.AbsoluteContent(region.ImagePath),
SmallImageUrl = (String.IsNullOrEmpty(region.ImagePath))?null:Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath,AppConfig.SmallThumbSuffix)),
MediumImageUrl = (String.IsNullOrEmpty(region.ImagePath))?null:Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath,AppConfig.MediumThumbSuffix)),
Name = region.Name,
MmName = region.MmName,
Description = region.Description,
MmDescription = region.MmDescription,
Latitude = region.Latitude,
Longitude = region.Longitude
};
regions.Add(contentRegion);
}
}
string json = JsonConvert.SerializeObject(regions);
if(!string.IsNullOrEmpty(json))
{
json = json.Trim(new char[] { '"' });
}
return new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new ObjectContent(json.GetType(),json,Configuration.Formatters.JsonFormatter)
};
}
Actually this code should return Json array. But when I parse data from client (from Android using Volley). It cannot be parsed into Json Array.
This is the data I get:
As you can see the double quote both in the beginning and at the end. The reason I cannot parse it into array in Volley is it is returning as a string because of that double. How can I serialize it trimming that quote? I used trim, but not removed.
You are unnecessarily complicating things. In Web API you can return JSON just by returning any object inside the built-in methods, the framework will serialize it for you.
public IHttpActionResult Get()
{
IEnumerable<Region> dbRegions = regionRepo.GetCachedRegions();
List<ContentRegion> regions = new List<ContentRegion>();
if(dbRegions != null && dbRegions.Count() > 0) {
foreach(var region in dbRegions)
{
ContentRegion contentRegion = new ContentRegion
{
Id = region.Id,
ImageUrl = Url.AbsoluteContent(region.ImagePath),
SmallImageUrl = (String.IsNullOrEmpty(region.ImagePath))?null:Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath,AppConfig.SmallThumbSuffix)),
MediumImageUrl = (String.IsNullOrEmpty(region.ImagePath))?null:Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath,AppConfig.MediumThumbSuffix)),
Name = region.Name,
MmName = region.MmName,
Description = region.Description,
MmDescription = region.MmDescription,
Latitude = region.Latitude,
Longitude = region.Longitude
};
regions.Add(contentRegion);
}
}
return Ok(regions);
}
As an aside: from what I can see you are mapping manually your domain objects into DTOs: take into consideration the use of an automatic mapping mechanism like AutoMapper.
I am not sure this is the best solution or not. I solved the problem using this way.
This is my action method
public HttpResponseMessage Get()
{
try
{
IEnumerable<Region> dbRegions = regionRepo.GetCachedRegions();
List<ContentRegion> regions = new List<ContentRegion>();
if (dbRegions != null && dbRegions.Count() > 0)
{
foreach (var region in dbRegions)
{
ContentRegion contentRegion = new ContentRegion
{
Id = region.Id,
ImageUrl = Url.AbsoluteContent(region.ImagePath),
SmallImageUrl = (String.IsNullOrEmpty(region.ImagePath)) ? null : Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath, AppConfig.SmallThumbSuffix)),
MediumImageUrl = (String.IsNullOrEmpty(region.ImagePath)) ? null : Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath, AppConfig.MediumThumbSuffix)),
Name = region.Name,
MmName = region.MmName,
Description = region.Description,
MmDescription = region.MmDescription,
Latitude = region.Latitude,
Longitude = region.Longitude
};
regions.Add(contentRegion);
}
}
string json = JsonConvert.SerializeObject(regions);
return new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new StringContent(json, Encoding.Default, "application/json")
};
}
catch
{
return Request.CreateResponse(HttpStatusCode.InternalServerError);
}
}
It's not required to convert object to json string.
You can try :
return Request.CreateResponse<List<ContentRegion>>(HttpStatusCode.OK,regions);
Not tested.
config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
Use this line in your WebApiConfig.
And here your code should be
public HttpResponseMessage Get()
{
IEnumerable<Region> dbRegions = regionRepo.GetCachedRegions();
List<ContentRegion> regions = new List<ContentRegion>();
HttpResponseMessage temp = ControllerContext.Request.CreateResponse(HttpStatusCode.OK, "");
if (dbRegions != null && dbRegions.Count() > 0)
{
foreach (var region in dbRegions)
{
ContentRegion contentRegion = new ContentRegion
{
Id = region.Id,
ImageUrl = Url.AbsoluteContent(region.ImagePath),
SmallImageUrl = (String.IsNullOrEmpty(region.ImagePath)) ? null : Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath, AppConfig.SmallThumbSuffix)),
MediumImageUrl = (String.IsNullOrEmpty(region.ImagePath)) ? null : Url.AbsoluteContent(CommonHelper.GetImageUrl(region.ImagePath, AppConfig.MediumThumbSuffix)),
Name = region.Name,
MmName = region.MmName,
Description = region.Description,
MmDescription = region.MmDescription,
Latitude = region.Latitude,
Longitude = region.Longitude
};
regions.Add(contentRegion);
}
}
temp = ControllerContext.Request.CreateResponse(HttpStatusCode.OK, regions);
return temp;
//string json = JsonConvert.SerializeObject(regions);
//if (!string.IsNullOrEmpty(json))
//{
// json = json.Trim(new char[] { '"' });
//}
//return new HttpResponseMessage(HttpStatusCode.OK)
//{
// Content = new ObjectContent(json.GetType(), json, Configuration.Formatters.JsonFormatter)
//};
}
