RFID Apis :

1. created get api for fetching user based on rfid here : https://github.com/vivekmaru36/Crud_operations_with_web_api/blob/master/Crud_app_with_mongo/Data_access_layer/CrudOperationsDL.cs

2. created api for registering as teacher : https://github.com/vivekmaru36/Crud_operations_with_web_api/blob/master/Crud_app_with_mongo/Data_access_layer/CrudOperationsDL.cs

3. updated and did lot of changes in getrecordbyrfid api and logincheck api

Crud_app

Uses asp.net 6.1 and mongo db

if you encounter any issues follow this link : v=MUO7X0pd8R0&list=PLwxiRZdZ4bZkldxU51cwo5B1xuN9hxvCM&ab_channel=VCoder

// read me its not proper anyways :

1. core web api template

2. create data acces layers folders --> inside that create inerface and class using add class options

3. download mongodb msi package to connect through data link : https://www.mongodb.com/try/download/community

4. create db using 'use' throuhg terminal than add datacollection in mongodb

5. go to vs studio add dependecy in controller

6. instal mongo db driver Install-Package MongoDB.Driver important links for above steps : https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-mongo-app?view=aspnetcore-7.0&tabs=visual-studio

7. after adding some things in app settings .json

8. you need to pass the connection string in mongo client in CrudoperationsDl.cs code inside appsettings.json : { "Databasesettings": { "ConnectionString": "mongodb://localhost:27017", "DatabaseName": "CrudOperations", "CollectionName": "UserDetails" }, "Logging": { "LogLevel": { "Default": "Information", "Microsoft.AspNetCore": "Warning" } }, "AllowedHosts": "*" }

code inside CrudOperationsDl.cs we also make new instances of mongoclient :

using Crud_app_with_mongo.Model; using MongoDB.Driver;

namespace Crud_app_with_mongo.Data_access_layer { public class CrudOperationsDL : ICrudOperationsDL { private readonly IConfiguration _configuration; // for mongo client private readonly MongoClient _mongoClient;

    public CrudOperationsDL(IConfiguration configuration) { 
        _configuration = configuration;
        _mongoClient=new MongoClient();
    }

    public async Task<InsertRecordResponse> Insert(InsertRecordRequest request)
    {
        // below is default code when implemented
        // throw new NotImplementedException();

        InsertRecordResponse response = new InsertRecordResponse();

        try
        {

        }
        catch (Exception ex)
        {
            response.IsSuccess = false;
            response.Message= "Exception Occured : "+ex.Message;
        }
        return response;

    }
}

}

9. passing the connection string inside mongoclient() --> get the string from appsetting.json

updated code inside CrudOperationsDL.cs :

using Crud_app_with_mongo.Model; using MongoDB.Driver;

namespace Crud_app_with_mongo.Data_access_layer { public class CrudOperationsDL : ICrudOperationsDL { private readonly IConfiguration _configuration; // for mongo client private readonly MongoClient _mongoClient;

    public CrudOperationsDL(IConfiguration configuration) { 
        _configuration = configuration;
        _mongoClient=new MongoClient(_configuration["Databasesettings:ConnectionString"]);
    }

    public async Task<InsertRecordResponse> Insert(InsertRecordRequest request)
    {
        // below is default code when implemented
        // throw new NotImplementedException();

        InsertRecordResponse response = new InsertRecordResponse();

        try
        {

        }
        catch (Exception ex)
        {
            response.IsSuccess = false;
            response.Message= "Exception Occured : "+ex.Message;
        }
        return response;

    }
}

}

crearting var for mongo database name and specifing connection with appropriate collection with insertrecordresponse function in insert record

// inside model folders as class code inside insertrecord.cs : using MongoDB.Bson; using MongoDB.Bson.Serialization.Attributes; using System.ComponentModel.DataAnnotations;

namespace Crud_app_with_mongo.Model { public class InsertRecordRequest { // ? --> means it can also be a null value [BsonId] [BsonRepresentation(BsonType.ObjectId)] public string? Id { get; set; }

    public string CreatedDate { get; set; }

    public string UpdatedDate { get; set;}

    [Required]
    [BsonElement(elementName:"Name")]
    public string FirstName { get; set; }

    [Required]
    public string LastName { get; set; }

    [Required]
    public int Age { get; set; }

    [Required]
    public string Contact {  get; set; }

    public double Salary {  get; set; }
}

// now creating the response body for this

public class InsertRecordResponse { 
    public bool IsSuccess {  get; set; }
    // the message contains why of issucces like if succes than why if fail than why fail ?
    public string Message {  get; set; } 

}

}

// inside data access layer folder as class code inside CrudOperationsDL.cs :

11. we have succesfull inserted data using web api current code inside : git repo

12. all apis done in swagger now testing in postman

{Testing using Postman}

part 6 :

13. downloand and install postman
14. find url of apis using swagger or launchsettings.json inside properties folder
15. url link : https://localhost:44367/ https://localhost:

"iisExpress": { "applicationUrl": "http://localhost:15599", "sslPort": 44367 }

16. postman testing done only for insert records jumping to completing the app

17. just incase : mongo url : mongodb://localhost:27017/

18. Completed
