I am receiving a large block of JSON information from an API call.
This example lists 2 of the items received; normally, this list will contain hundreds.
The JSON received is:

So far I have tried creating classes for the data, but it seems to give me no information.
In order to process the data, I had to change all the properties names, because many contain a dash:
For example, Created-at is now Created_at
I used jsonutils.com to create the VB.Net classes.
I load the JSON into a string called Change_String.
If anyone can explain what I'm doing wrong, I would appreciate it
Dim changed_string as string = "JSON INPUT _ instead of -"
Dim obj As Attributes
obj = JsonConvert.DeserializeObject(Of Attributes)(changed_string)
msgbox(obj.name)

I gave it a second look.
The classes generated by the online service are not exactly spectacular.
This is a modified class structure that should provide the correct results.
I compacted everything in a single class named JSON_Organizations, which contains all the classes needed by the JSON deserializer.
All the properties are renamed using JSON Attributes, so the bad names are taken care of.
Sample converter:
Imports Newtonsoft.Json
Dim JSONObject As String = "[The JSON Object]"
Dim Organizations As JSON_Organizations.RootObject = New JSON_Organizations.RootObject
Organizations = JsonConvert.DeserializeObject(Of JSON_Organizations.RootObject)(JSONObject)
The JSON_Organizations container class:

I'm using entity framework code first. The below keeps kicking out the unable to determine the principal end of an association. Basically I can't figure out how to get one to many relationships between the auto generated identity table and my own tables with code first.
public class applicationUser : Identity
{
public User user {get;set;}
}
//and then a dependant class called User
public class User
{
public in Id {get;set;}
public string Name {get;set;}
[ForeignKey("Identity")]
public string IdentityId {get;set;}
public ApplicationUser Identity {get;set;}
public string UserPicLocation {get;set;}
}
You're using [ForeignKey()] wrong. The value of [ForeignKey()] should be the name of the property that contains the key of the referenced object.
You should also mark the property that contains the key in the referenced object as the private key with [Key]
Try this:
public class applicationUser : Identity
{
public int UserId {get; set;}
[ForeignKey("UserId")]
public User user {get;set;}
}
and then another class called User
public class User
{
[Key]
public int Id {get;set;}
public string Name {get;set;}
public string IdentityId {get;set;}
public ApplicationUser Identity {get;set;}
public string UserPicLocation {get;set;}
}
I fixed it by setting the primary key as both the primary and foreign key in the dependant table
I have a DTO like this (note this is only a sample dto) :
public class SomeClassDTO
{
public guid Id {get;set;}
public string Name {get;set;}
public IList<Register1> Registers1 {get;set;}
public IList<Register2> Registers2 {get;set;}
}
and the class:
public class SomeClass
{
public guid Id {get;set;}
public string Name {get;set;}
}
I need something like this:
Mapper.CreateMap<SomeClass, SomeClassDTO>()
.ForMember(dto=>dto.Registers1, opt=>opt.MapFrom(src=>_session.Query<Register1>.ToList()))
.ForMember(dto=>dto.Registers2, opt=>opt.MapFrom(src=>_session.Query<Register2>.ToList()));
Where _session is an instance per request of the nhibernate session.
Ok, I need to get the collections in the dto populated from the values i get from DB using nhibernate session. (of course those collection has nothing to do with the class: SomeClass and they don't have any relations to it.
Dont know how to inject ISession to MapFrom or ResolveUsing.
The DI Container is Autofac, and the project type is WebApi2
Please Help
Let's say I have a class:
public class Person
{
public string Name{get;set;}
public string Email {get;set;}
public string GoogleId {get;set;}
public string FacebookId {get;set;}
}
If I want to make the email unique I will use the unique constraint bundle.
But I want to make both the googleId and the facebookId properties as a single unique constraint side by side with the email constraint (while non of them is the id).
Is it possible?
Use the UniqueConstraints bundle:
public class Person
{
public string Name {get;set;}
[UniqueConstraint]
public string Email {get;set;}
public string GoogleId {get;set;}
public string FacebookId {get;set;}
[UniqueConstraint]
public string GoogleAndFacebookIds { get;set; }
}
Just make sure you update GoogleAndFacebookIds everytime you update either GoogleId or FacebookId. I was doing this so much I ended up using a simple interface on all my classes that did this sort of thing:
public interface ICombinedConstraints
{
string UniqueId { get; set; }
void UpdateConstraints();
}
So,
public class Person : ICombinedConstraints
{
public string Name{get;set;}
[UniqueConstraint]
public string Email {get;set;}
public string GoogleId {get;set;}
public string FacebookId {get;set;}
[UniqueConstraint]
public string UniqueId { get; set; }
public void UpdateConstraints()
{
UniqueId = GoogleId + FacebookId;
}
}
You cannot do that. Raven doesn't provide any possibility to enforce unique constraints on the property. If you want to do that you need separate sets of documents (see link below)
Unique constraints in Raven
Update:
It seems that you can also try to use bundles to implement unique constraints in the object.
Bundle: Unique constraints
I am new to PetaPoco and initially I was liking it but then hit a wall which I simply dont know how to search for.
I have a object which needs to set a property within one of its properties, ie Job.Min.BaseValue. The source of this data is "min_mb".
So basically my object is not a direct mapping of the source table
public class Usage
{
public Decimal BaseValue {get;set;}
public Decimal BaseScale {get;set;}
public Decimal BaseUnit {get;set;}
}
[PetaPoco.TableName("data")]
[PetaPoco.PrimaryKey("date, client_name")]
[PetaPoco.ExplicitColumns]
public class Job
{
[PetaPoco.Column("date")]
public DateTime Date {get;set;}
[PetaPoco.Column("client_name")]
public String ClientName {get;set;}
public Usage Min {get;set;}
public CommvaultJob() { Min = new Usage() { BaseScale=1024, BaseUnit="MB" }; }
}
I think you're just missing the extra type when you call Fetch or Query. This worked for me :
Calling PetaPoco :
var allData = _db.Fetch<TestJobPoco,Usage>("select * from dataTEST");
return View( allData);
The pocos :
[PetaPoco.ExplicitColumns]
public class Usage
{
public Usage()
{
BaseScale=1024;
BaseUnit="MB";
}
[PetaPoco.Column("base_value")]
public Decimal BaseValue {get;set;}
[PetaPoco.Ignore]
public Decimal BaseScale {get;set;}
[PetaPoco.Ignore]
public string BaseUnit {get;set;}
}
[PetaPoco.TableName("dataTEST")]
[PetaPoco.PrimaryKey("id")]
[PetaPoco.ExplicitColumns]
public class TestJobPoco
{
[PetaPoco.Column("id")]
public int Id {get;set;}
[PetaPoco.Column("date")]
public DateTime Date {get;set;}
[PetaPoco.Column("client_name")]
public String ClientName {get;set;}
public Usage Min {get;set;}
public TestJobPoco()
{
//Min = new Usage() { BaseScale=1024, BaseUnit="MB" };
}
}
My test database has an id, date, client_name and base_value columns. The primary key is id so it's slightly different than yours but this shouldn't change the way the poco mapping happens.
If your objects do not map with the table structure, an ORM can't help much.
You will need to do the mapping manually or made new shadow properties that copy the values of the other fields, but this added complexity will defeat the purpose of an ORM.
