Can't Map An Entity in EfCore

Can't Map An Entity in EfCore - c#

I am Working on a Spa Project using Asp.net core API
So Users Can Enter WebSite And Booking An Health Program
Without Payment
Each Health program has its own duration, the duration of which is the time that the guest will spend in the spa with his Health Program, Each Duration has two Room And DurationType, DurationType is An Enum representing (Week Or nights)
Each Room Has its Owe Room type And Price And Discount
Like Single Room And Shared Room
My Problem
How To Map Booking In Database With EFcore
the booking must Contain one Health Program With one Duration And One Room
And The Relations is Health program has A collection Form Durations
And Durations have A collection Of Rooms
this is My Implementation

Deserializing JSON into C# Product ID with Shopify API

asp.net EF code first model for PBX managment

I want to make the simple application to use with my PBX. I want to manage the providers and Lines tat connected to my PBX. The main objects are Provider and Line. Every provider has some lines connected to it. Lines can be added or deleted enabled or disabled and reserved. I want to keep the status of lines and history of actions in one table. Does this right solution or I need to create another table for history?
public class Line
{
public int LineId { get; set; }
public Provider Provider { get;set;}
public string Login { get; set; }
public string Pass { get; set; }
public string Domain { get; set; }
public string ProjectOwner { get; set; }
public string Project { get; set; }
public string OutNumber { get; set; }
public string InNumber { get; set; }
public string Description { get; set; }
public DateTime Begin_datetime { get; set; }
public DateTime End_datetime { get; set; }
public Human TechGuy { get; set; }
public Human Manager { get; set; }
}
public class Provider
{
public int ProviderId { get; set; }
public string Name { get; set; }
public string OurSideData { get; set; }
public string TheirSideData { get; set; }
public string Description { get; set; }
public DateTime Begin_datetime { get; set; }
public DateTime End_datetime { get; set; }
public Currency Currency { get; set; }
}
What is the best solution for the code first model creating in the logic like that? Maybe I need to add some additional fields?

You need another table for history. Something like:
public class Line
{
public int LineId { get; set; }
public virtual Provider Provider { get; set; }
public string Login { get; set; }
public string Pass { get; set; }
public string Domain { get; set; }
public string ProjectOwner { get; set; }
public string Project { get; set; }
public string OutNumber { get; set; }
public string InNumber { get; set; }
public string Description { get; set; }
public DateTime Begin_datetime { get; set; }
public DateTime End_datetime { get; set; }
public Human TechGuy { get; set; }
public Human Manager { get; set; }
public virtual ICollection<LineStatusHistory> ChangeHistory { get; } = new HashSet<LineStatusHistory>();
}
public class LineStatusHistory
{
[Key( )]
public int LineId { get; set; }
[Key()]
public int LineStatusHistoryId { get; set; }
public virtual Line Line { get; set; }
public DateTime ChangeDate { get; set; }
public string Change { get; set; }
}
public class Provider
{
public int ProviderId { get; set; }
public string Name { get; set; }
public string OurSideData { get; set; }
public string TheirSideData { get; set; }
public string Description { get; set; }
public DateTime Begin_datetime { get; set; }
public DateTime End_datetime { get; set; }
public Currency Currency { get; set; }
public virtual ICollection<Line> Lines { get; } = new HashSet<Line>();
}

FormatException during Json.net deserialization

I'm faced wiht an error, and I don't know how to correct it. I don't understand why it comes.
System.FormatException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
The exception comes when I try to deserialize a JSON into objects that I created. (The second line code is throwing the exception)
List<Connection> connections = new List<Connection>();
var root = JsonConvert.DeserializeObject<RootObject2>(content);
connections = root.connections;
Here is the JSON that I want to use:
http://transport.opendata.ch/v1/connections?from=lausanne&to=fribourg
And here are my objects:
public class RootObject2
{
public List<Connection> connections { get; set; }
}
public class Connection
{
public Stop from { get; set; }
public Stop to { get; set; }
public string duration { get; set; }
public int? transfers { get; set; }
public Service service { get; set; }
public List<string> products { get; set; }
public int? capacity1st { get; set; }

public int? delay { get; set; }
public string platform { get; set; }
public Prognosis prognosis { get; set; }
public string realtimeAvailability {get; set;}
public Station location { get; set; }
}
public class Station
{
public string id { get; set; }
public string name { get; set; }
public int? score { get; set; }
public Coordinate coordinate { get; set; }
public double? distance { get; set; }
}
public class Service
{
public string regular { get; set; }
public string irregular { get; set; }
}
public class Section
{
public Journey journey { get; set; }
public Walk walk { get; set; }
public Stop departure { get; set; }
public Stop arrival { get; set; }
}
public class Journey
{
public string name { get; set; }
public string category { get; set; }
public string subcategory { get; set; }
public int? categoryCode { get; set; }
public string number { get; set; }
public string #operator { get; set; }
public string to { get; set; }
public List<Stop> passList { get; set; }
public int? capacity1st { get; set; }
public int? capacity2nd { get; set; }
}
public class Walk
{
public string duration { get; set; }
}
public class Prognosis
{
public string platform { get; set; }
public string arrival { get; set; }
public string departure { get; set; }
public int? capacity1st { get; set; }
public int? capacity2nd { get; set; }
}
public class Coordinate
{
public string type { get; set; }
public double x { get; set; }
public double y { get; set; }
}
The deserialization is on a try and catch block, and nothing is catched.
Also I am doing this on Android.

Based on json data.
Arrival property in Stop class should be DateTime?.

represent a help table in entity framework

Table 1: Articles
Table 2: ArticleCategories
how do I represent the relationship between the two tables which is a 1->1 relationship:
I can do the following, but I'm not sure it's the correct way :
public class Article
{
public int ArticleIndex { get; set; }
public int Category { get; set; }
public Guid User { get; set; }
public int Parent { get; set; }
public int Level { get; set; }
public int Order { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateExpires { get; set; }
public bool Show { get; set; }
public string Title { get; set; }
public string TitleHtml { get; set; }
public string Content { get; set; }
public string ContentHtml { get; set; }
public string ShortTitle { get; set; }
public ArticleCategory Category { get; set; }
}
public class ArticleCategory
{
public int CategoryIndex { get; set; }
public string Name { get; set; }
}

By convention, Code First expects an Id property for each class/table. Then you can do something like this:
public class Article
{
public int Id { get; set; }
public int ArticleIndex { get; set; }
public int Category { get; set; }
public Guid User { get; set; }
public int Parent { get; set; }
public int Level { get; set; }
public int Order { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateExpires { get; set; }
public bool Show { get; set; }
public string Title { get; set; }
public string TitleHtml { get; set; }
public string Content { get; set; }
public string ContentHtml { get; set; }
public string ShortTitle { get; set; }
public int ArticleCategoryId { get; set; }
public virtual ArticleCategory ArticleCategory { get; set; }
}
public class ArticleCategory
{
public int Id { get; set; }
public int CategoryIndex { get; set; }
public string Name { get; set; }
public virtual ICollection<Article> Articles { get; set; }
}
Note the virtual keyword. EF Code First needs this so it can perform its magic behind the scenes.
Now, if you are working with an Article, you can get all it's category info by doing article.ArticleCategory, and if you have an ArticleCategory you can find out what article it refers to with articleCategory.Articles.Single().
