i have created a simple API controller and added the following method in it:
public IQueryable<tbl_Book> GetBooks()
{
//AspNetUser user = new AspNetUser();
return _context.tbl_Book;
}
and then i have created an MVC controller to consume this API as follow:
public ActionResult Index()
{
IEnumerable<tbl_Book> books = null;
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:57368/api/");
var responseTask = client.GetAsync("Admin");
responseTask.Wait();
var result = responseTask.Result;
if(result.IsSuccessStatusCode)
{
var readTask = result.Content.ReadAsAsync<IEnumerable<tbl_Book>>();
readTask.Wait();
books = readTask.Result;
}
else
{
ModelState.AddModelError(string.Empty, "Error occured while fetching data from api");
}
}
return View(books);
}
it works just fine and gives the result but i want to get data from two tables which are tbl_Categories and AspNetusers which i do like this:
public IQueryable<tbl_Book> GetBooks()
{
//AspNetUser user = new AspNetUser();
return _context.tbl_Book.Include(x=>x.AspNetUser).Include(x=>x.tbl_Category);
}
book model has foreign keys from tbl_Categories and AspNetUsers but when i try to consume this above API with include functions it gives null result.

I made an api which have some data for example www.example.com/data/select?indent=on&q=title:asthma
gives the data in JSON format like
{
"responseHeader":{
"status":0,
"QTime":2,
"params":
{
"q":"title:asthma",
"indent":"on",
"wt":"json"
},
"response":{"numFound":1,"start":0, docs:[
{
"tstamp": "xxxx"
"id": "xxxxx"
"title": "Asthma is a medical term"
"url": "www.example.com/xxxx"
"content":"xxxxx"
}]}
}}
I want to call the same url from my .netcore application such that I can have title and url from the response and show it to my .netcore application.
As a new to .netcore it is pretty tricky to get used to MVC architecture. My model look like this
namespace searchEngineTesting.Models
{
public class SearchModel
{
public string Title {get; set;}
public string Source {get; set;}
}
}
How can I use controller that whenever triggers take a string as an input for example cancer and put it to the title of the api like www.example.com/data/select?indent=on&q=title:cancer and fetch the title and url from the response.
You could fetch json data like below:
[HttpGet]
public async Task<JsonResult> Get()
{
var model = new SearchModel();
var url = "https://localhost:5001/api/values/test";//it should be the url of your api
using (var httpClient = new HttpClient())
{
using (var response = await httpClient.GetAsync(url))
{
using (var content = response.Content)
{
//get the json result from your api
var result = await content.ReadAsStringAsync();
var root = (JObject)JsonConvert.DeserializeObject(result);
var items = root.SelectToken("responseHeader").Children().OfType<JProperty>().ToDictionary(p => p.Name, p => p.Value);
foreach(var item in items)
{
if(item.Key== "response")
{
var key = item.Value.SelectToken("").OfType<JProperty>().ToDictionary(p => p.Name, p => p.Value);
foreach (var k in key)
{
if(k.Key== "docs")
{
var tests = JsonConvert.DeserializeObject<JArray>(k.Value.ToString());
var data = k.Value.SelectToken("").Children().First();
var test = data.SelectToken("").Children().OfType<JProperty>().ToDictionary(p => p.Name, p => p.Value);
foreach (var t in test)
{
if (t.Key == "url")
{
model.Source = t.Value.ToString();
}
else if (t.Key=="title")
{
model.Title = t.Value.ToString();
}
}
}
}
}
}
return new JsonResult(model);
}
}
}
}
[HttpGet("[Action]")]
public string test()
{
//for easy testing,I just read your json file and return string
var jsonstring = System.IO.File.ReadAllText("C:\\test.json");
return jsonstring;
}
I am newbie in ASP.NET. Is there a possible way to save the current logged user into the form database when the form is submitted?
(i.e) When multiple registered users enter a form and click save their user name is saved into the contents of form database.
I had googled it but couldn't find related topics (maybe I used the wrong keywords). If methods are available kindly suggest link.
[Edit]
I have used asp.net identity for authentication.
My current code for save
public ActionResult NewPR()
{
var depts = _context.Depts.ToList();
var currencytypes = _context.Currencytypes.ToList();
var viewModel = new NewPRViewModel
{
PRview = new PRview(),
Currencytypes = currencytypes,
};
return View("NewPR", viewModel);
}
[HttpPost]
public ActionResult Save(PRview prview)
{
if (!ModelState.IsValid)
{
var viewModel = new NewPRViewModel
{
PRview = prview,
Currencytypes = _context.Currencytypes.ToList()
};
return View("NewPR", viewModel);
}
if (prview.Id == 0)
_context.PRviews.Add(prview);
else
{
var prviewInDb = _context.PRviews.Single(c => c.Id == prview.Id);
prviewInDb.SupplierName = prview.SupplierName;
prviewInDb.Brand = prview.Brand;
prviewInDb.Qty = prview.Qty;
prviewInDb.Unitprice = prview.Unitprice;
}
_context.SaveChanges();
return RedirectToAction("Index", "PRview");
}
So I implemented Identity for my core project. I have successfully completed my Registration. So while trying to login using the _signInManager.PasswordSignInAsync I am getting the exception Invalid object name 'AspNetRoleClaims'.
I know this is because the AspNetRoleClaims table is not present in my database. But idont know the structure of this table nor do I know how to create it automatically like in mvc.
Can somebody enlighten me why this table is used. Or at least what is the expected structure.
public async Task<IActionResult> RegisterSubmit(Registermodel rm)
{
if (rm.role == "" || rm.role.Trim() == "-1")
{
return View();
}
else
{
var user = new ApplicationUser { UserName = rm.username, Email = rm.username, DeptName = rm.role };
var result = await _userManager.CreateAsync(user, rm.Password);
if (result.Succeeded)
{
_userManager.GenerateEmailConfirmationTokenAsync(user);
await _signInManager.SignInAsync(user, isPersistent: false);
var roleexists = await _roleManager.RoleExistsAsync(rm.role);
if (!roleexists)
{
var role = new IdentityRole();
role.Name = rm.role;
await _roleManager.CreateAsync(role);
}
await _userManager.AddToRoleAsync(user, rm.role);
user.Claims.Add(new IdentityUserClaim<string>
{
ClaimType = "ProductUploadRequest",
ClaimValue = "Allow"
});
}
return View("Login");
}
}
This is my login method.
public async Task<IActionResult> Login(LoginIdentityModel lim)
{
var result = await _signInManager.PasswordSignInAsync(lim.username, lim.password,false, lockoutOnFailure: false); //exception comes here
if (result.Succeeded)
{
var user = await _userManager.GetUserAsync(HttpContext.User);
UserProfileInfo userProfileInfo = new UserProfileInfo();
userProfileInfo.UserId = new Guid(user.Id);
userProfileInfo.FirstName = "test";
userProfileInfo.UserName = lim.username;
userProfileInfo.LastVisit = DateTime.Now;
string query2 = "select ud.UserId,dp.Id DeptId,dp.Name DeptName,rd.Id RoleId,rd.Name RoleName,ud.[ReadWrite] from UserInDepartment ud inner join Department dp on ud.DeptId=dp.Id inner join RolesInDepartment rd on dp.Id=rd.DeptId and ud.RoleId=rd.Id where ud.UserId='" + user.Id + "' and dp.IsEnable=1 and rd.IsEnable=1 and ud.IsEnable=1";
var userProfile = await _departMentalContext.UserProfiles.FromSql(query2).SingleOrDefaultAsync();
if (userProfile != null)
{
Dictionary<int, string> deptValues = new Dictionary<int, string>() { { userProfile.DeptId, userProfile.DeptName } };
userProfileInfo.Dept = deptValues;
Dictionary<int, string> roleValues = new Dictionary<int, string>() { { userProfile.RoleId, userProfile.RoleName } };
userProfileInfo.Role = roleValues;
userProfileInfo.ReadOrWrite = userProfile.ReadWrite;
HttpContext.Session.SetObject(UserProfileSessionName, userProfileInfo);
}
return View("/Home/DashBoard");
}
return View();
}
As you are using EF, you should be able to update your model database.
You can use CLI command (learn.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet).
Or if you are using Visual Studio, in the package manager console, you can execute those commands :
Add-Migration "init"
Update-Database
Commands allows you tu update table in your database. Also, it will create migrations files, which are a "picture" of your models. When the command Update-Database is executed, it loads the last migration file.
I have an ODataController with 2 methods:
[EnableQuery]
public SingleResult<item> Getitem([FromODataUri] System.Guid key)
{
return SingleResult.Create(db.items.Where(item=> item.guid == key));
}
public async Task<IHttpActionResult> Postitem([FromODataUri] System.Guid key, [FromBody] double itemId)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
//Find the correct account
item i = await db.items.FirstAsync(item=> item.guid == key);
if (i == null)
{
return NotFound();
}
//Update the account field we are using for id
i.itemId = itemId;
//Save the changes
try
{
await db.SaveChangesAsync();
}
catch (DbUpdateConcurrencyException)
{
if (!itemExists(key))
{
return NotFound();
}
else
{
throw;
}
}
return Updated(i);
}
private bool itemExists(System.Guid key)
{
return db.items.Count(e => e.guid == key) > 0;
}
With the standard WebApiConfig:
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
config.EnableCors();
// Web API configuration and services
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<item>("items");
config.Routes.MapODataServiceRoute("odata", "odata", builder.GetEdmModel());
And I can type mydomain.com/odata/items(guid'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX') in the url bar and get the database object as json just fine.
But when I try the following client code:
var itemGuid = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
var itemId = "55555";
using (WebClient wc = new WebClient())
{
wc.UseDefaultCredentials = true;
var domain = "mydomain.com";
var url = domain + "/odata/items(guid'" + itemGuid + "')";
var data = new NameValueCollection();
data["itemId"] = itemId;
byte[] temp = wc.UploadValues(url, "POST", data);
context.Response.Write(Encoding.UTF8.GetString(temp));
}
I get The remote server returned an error: (404) Not Found.
I know it's probably some simple mistake, but been messing around with it too long and I'm new to asp.net.
I think I may have figured it out and it makes sense. So if you create an OdataController you sorta just have your default Post to create a new item, Patch to change/update an update, Put to replace an item with a new one...
Then if you want custom api calls you need to use actions: http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/odata-v3/odata-actions
So I was just doing it all wrong. I just assumed you could put Post in front of some function name and it would be a Post opperation with custom arguments.
"How can i use engine in my console application"
I shouldn't use the ITemplate-interface and Transform-Method.
I am using Tridion 2011
Could anyone please suggest me.
You can't. The Engine class is part of the TOM.NET and that API is explicitly reserved for use in:
Template Building Blocks
Event Handlers
For all other cases (such as console applications) you should use the Core Service.
There are many good questions (and articles on other web sites) already:
https://stackoverflow.com/search?q=%5Btridion%5D+core+service
http://www.google.com/#q=tridion+core+service
If you get stuck along the way, show us the relevant code+configuration you have and what error message your get (or at what step you are stuck) and we'll try to help from there.
From a console application you should use the Core Service. I wrote a small example using the Core Service to search for items in the content manager.
Console.WriteLine("FullTextQuery:");
var fullTextQuery = Console.ReadLine();
if (String.IsNullOrWhiteSpace(fullTextQuery) || fullTextQuery.Equals(":q", StringComparison.OrdinalIgnoreCase))
{
break;
}
Console.WriteLine("SearchIn IdRef:");
var searchInIdRef = Console.ReadLine();
var queryData = new SearchQueryData
{
FullTextQuery = fullTextQuery,
SearchIn = new LinkToIdentifiableObjectData
{
IdRef = searchInIdRef
}
};
var results = coreServiceClient.GetSearchResults(queryData);
results.ToList().ForEach(result => Console.WriteLine("{0} ({1})", result.Title, result.Id));
Add a reference to Tridion.ContentManager.CoreService.Client to your Visual Studio Project.
Code of the Core Service Client Provider:
public interface ICoreServiceProvider
{
CoreServiceClient GetCoreServiceClient();
}
public class CoreServiceDefaultProvider : ICoreServiceProvider
{
private CoreServiceClient _client;
public CoreServiceClient GetCoreServiceClient()
{
return _client ?? (_client = new CoreServiceClient());
}
}
And the client itself:
public class CoreServiceClient : IDisposable
{
public SessionAwareCoreServiceClient ProxyClient;
private const string DefaultEndpointName = "netTcp_2011";
public CoreServiceClient(string endPointName)
{
if(string.IsNullOrWhiteSpace(endPointName))
{
throw new ArgumentNullException("endPointName", "EndPointName is not specified.");
}
ProxyClient = new SessionAwareCoreServiceClient(endPointName);
}
public CoreServiceClient() : this(DefaultEndpointName) { }
public string GetApiVersionNumber()
{
return ProxyClient.GetApiVersion();
}
public IdentifiableObjectData[] GetSearchResults(SearchQueryData filter)
{
return ProxyClient.GetSearchResults(filter);
}
public IdentifiableObjectData Read(string id)
{
return ProxyClient.Read(id, new ReadOptions());
}
public ApplicationData ReadApplicationData(string subjectId, string applicationId)
{
return ProxyClient.ReadApplicationData(subjectId, applicationId);
}
public void Dispose()
{
if (ProxyClient.State == CommunicationState.Faulted)
{
ProxyClient.Abort();
}
else
{
ProxyClient.Close();
}
}
}
When you want to perform CRUD actions through the core service you can implement the following methods in the client:
public IdentifiableObjectData CreateItem(IdentifiableObjectData data)
{
data = ProxyClient.Create(data, new ReadOptions());
return data;
}
public IdentifiableObjectData UpdateItem(IdentifiableObjectData data)
{
data = ProxyClient.Update(data, new ReadOptions());
return data;
}
public IdentifiableObjectData ReadItem(string id)
{
return ProxyClient.Read(id, new ReadOptions());
}
To construct a data object of e.g. a Component you can implement a Component Builder class that implements a create method that does this for you:
public ComponentData Create(string folderUri, string title, string content)
{
var data = new ComponentData()
{
Id = "tcm:0-0-0",
Title = title,
Content = content,
LocationInfo = new LocationInfo()
};
data.LocationInfo.OrganizationalItem = new LinkToOrganizationalItemData
{
IdRef = folderUri
};
using (CoreServiceClient client = provider.GetCoreServiceClient())
{
data = (ComponentData)client.CreateItem(data);
}
return data;
}
Hope this gets you started.
