How to control models included in NSwag document - asp.net

I have 2 areas in my ASP.NET Core 3.1 API and models in each of them. I'm trying to produce 2 swagger documents, each for its area.
Operations are filtered based on IOperationProcessor, and all operations are correct. However, each document includes all documents from both areas.
What is the way to control which models included in which document?
This is what I have at the moment:
services.AddOpenApiDocument(swagger =>
{
swagger.DocumentName = "admin";
swagger.OperationProcessors.Add(new Swagger.AdminOperationProcessor());
swagger.SchemaNameGenerator = new Swagger.SchemaNameGenerator();
});
services.AddOpenApiDocument(openApi =>
{
openApi.DocumentName = "public";
openApi.OperationProcessors.Add(new Swagger.PublicOperationProcessor());
openApi.SchemaNameGenerator = new Swagger.SchemaNameGenerator();
openApi.PostProcess = (x) =>
{
};
});

After looking for ages, what I had to do is a bit of a botched solution. Using ISchemaNameGenerator replace not desired names into something else (I replace "." to "_"). Then using PostProcess remove them from generated schema. ExcludedTypeNames doesn't work for some reason.
var excludedList = new List<string>();
// this is called first
settings.SchemaNameGenerator = new SchemaNameGenerator(x =>
{
if (!typeNamespaces.Any(n => x.FullName.StartsWith(n)))
{
excludedList.Add(x.FullName);
}
return !typeNamespaces.Any(n => x.FullName.StartsWith(n));
});
// Post process relies on excluded list, otherwise it won't work
settings.PostProcess = (doc) =>
{
foreach (var exItem in excludedList)
{
var formatted = exItem.Replace(".", "_");
if (doc.Definitions.ContainsKey(formatted))
{
doc.Definitions.Remove(formatted);
}
}
};
The SchemaNameGenerator is:
public class SchemaNameGenerator : ISchemaNameGenerator
{
private Func<Type, bool> excludePredicate;
public SchemaNameGenerator(Func<Type, bool> excludePredicate = null)
{
this.excludePredicate = excludePredicate;
}
public string Generate(Type type)
{
var displayAttr = type
.GetCustomAttributes(typeof(DisplayNameAttribute), true)
.Cast<DisplayNameAttribute>()
.FirstOrDefault();
if (excludePredicate != null)
{
if (excludePredicate(type))
{
return type.FullName.Replace(".", "_");
}
}
return displayAttr?.DisplayName ?? type.Name;
}
}
If anybody has a better idea, please let me know.

How can add several fields to NEST?

I use Generic and Reflection, so the main problem is add several fields. When i use this code with one field it OK but when i try somehow add new fields it doesn't work:
public static ISearchResponse<T> PartSearch<T>(ElasticClient client, string query, List<string> fieldList = null, int from = 0, int size = 1) where T : class
{
if (client == null)
throw new ArgumentNullException();
if (String.IsNullOrEmpty(query))
throw new ArgumentNullException();
ISearchResponse<T> results;
if (fieldList == null)
{
results = client.Search<T>(q =>
q.Query(q =>
q.QueryString(qs => qs.Query(query))
).From(from).Size(size)
);
}
else
{
results = client.Search<T>(q =>
q.Query(q => q
.QueryString(qs =>
{
//This place where i try to add several fields
List<Field> fildArray = new List<Field>();
foreach (var arg in fieldList)
{
var fieldString = new Field(typeof(T).GetProperty(arg));
fildArray.Add(fieldString);
}
qs.Fields(f => f.Field(fildArray));
qs.Query(query);
return qs;
})
).From(from).Size(size)
);
}
return results;
}
I created an example using Lenient() that can help you with your question:
https://github.com/hgmauri/elasticsearch-with-nest/blob/master/src/Sample.Elasticsearch.Domain/Abstractions/NestExtensions.cs
Problem was in one QueryString parameter Lenient:

Fixed this by setting it on True.

How to declare public var and return in controller mvc

I have passed two arguments from view page to controller. but i dont know how to return this.."var Source". It should error show
[HttpPost]
public JsonResult FilterbyAutoComplete(string prefix,string filterBy)
{
VGLMSEntities2 db = new VGLMSEntities2();
var Source="";
if (filterBy == "Patient Name")
{
Source = db.Patient_Registeration.Where(m => m.PatientName.StartsWith(prefix)).Select(x => new { label = x.PatientName, val = x.PatientName }).ToList();
}
return Json(Source );
}
var keyword is just a syntactic sugar, it doesn't really exists, it just tells the compiler to take whatever on the right and use it the same.
I believe you may want to use the type 'object' instead for that case.
You can also just do
if (...)
return db.Patient_Registeration....
return Json(); // In case condition didn't catch
you can use dynamic
[HttpPost]
public JsonResult FilterbyAutoComplete(string prefix,string filterBy)
{
VGLMSEntities2 db = new VGLMSEntities2();
dynamic Source=null;
if (filterBy == "Patient Name")
{
Source = db.Patient_Registeration.Where(m => m.PatientName.StartsWith(prefix)).Select(x => new { label = x.PatientName, val = x.PatientName }).ToList();
}
return Json(Source );
}

Post data with free-jqgrid, what are the code in client and Web API side?

I am using ASP.NET MVC 6 Web API. In the View I use free-jqgrid.
Let's borrow Oleg's free jqgrid data to demonstrate my purpose. We already have the table shown.
Next I am going to add new Vendor. Please notify that there is primary key id(identity column) in the database. We don't want it displaying in the screen.
In VendorRespository.cs, I add the new Vendor as
public void AddVendor(Vendor item)
{
using (VendorDataContext dataContext = new VendorDataContext())
{
dataContext.Database.Connection.ConnectionString = DBUtility.GetSharedConnectionString(
"http://centralized.admin.test.com");
var newVendor = dataContext.Vendors.Create();
newVendor.Company = item.Company;
newVendor.ContactName = item.ContactName;
newVendor.ContactPhone = item.ContactName;
newVendor.UserName = item.UserName;
newVendor.UserKey = item.UserKey;
newVendor.Active = item.Active;
newVendor.FacilityId =item.FacilityId;
newVendor.ClientID = item.ClientID;
dataContext.SaveChanges();
}
}
My questions:
Not sure the script like?
<script>
API_URL = "/VendorManagement/";
function updateDialog(action) {
return {
url: API_URL
, closeAfterAdd: true
, closeAfterEdit: true
, afterShowForm: function (formId) { }
, modal: true
, onclickSubmit: function (params) {
var list = $("#jqgrid");
var selectedRow = list.getGridParam("selrow");
rowData = list.getRowData(selectedRow);
params.url += rowData.Id;
params.mtype = action;
}
, width: "300"
};
}
jQuery("#jqgrid").jqGrid('navGrid',
{ add: true, edit: true, del: true },
updateDialog('PUT'),
updateDialog('POST'),
updateDialog('DELETE')
);
In the controller, not sure what is the code?
// POST
public HttpResponseMessage PostVendor(Vendor item)
{
_vendorRespository.AddVendor(item);
var response = Request.CreateResponse<Vendor>(HttpStatusCode.Created, item);
string uri = Url.Link("DefaultApi", new { id = item.Id });
response.Headers.Location = new Uri(uri);
return response;
}
My code has many compiling errors such as
'HttpRequest' does not contain a definition for 'CreateResponse' and the best extension method overload 'HttpRequestMessageExtensions.CreateResponse(HttpRequestMessage, HttpStatusCode, Vendor)' requires a receiver of type 'HttpRequestMessage'
Please help me to get rid of the error and inappropriate code.
EDIT:
I borrowed the code snippet from here.
I need add the code such as
[Microsoft.AspNet.Mvc.HttpGet]
public dynamic GetVendorById(int pkey)
{
return null;
}
And
// POST
[System.Web.Http.HttpPost]
public HttpResponseMessage PostVendor(Vendor item)
{
_vendorRespository.AddVendor(item);
var response = Request.CreateResponse<Vendor>(HttpStatusCode.Created, item);
string uri = Url.Link("/VendorManagement/GetVendorById", new { id = item.pkey });
response.Headers.Location = new Uri(uri);
return response;
}

How to auto setup MOQ by given parameters and result in an object[]?

I want to automate the Setup code by a given array containing expected result and parameters.
Something like data driven setup.
My existing code:
var mock = new Mock<ILogin>();
var testDataTable = new object[,]
{
{ LoginResult.Success, "Jack", "123!##"}
, { LoginResult.WrongPassword, "Jack", "123321"}
, { LoginResult.NoSuchUser, "Peter", "123!##"}
};
// ForEachRow is my own extension method
testDataTable.ForEachRow((row) =>
{
var result = (LoginResult)row[0];
var username = (string)row[1];
var password = (string)row[2];
mock.Setup(o => o.Login(
It.Is<string>(u => u == username),
It.Is<string>(p => p == password)
)).Returns(result);
});
return mock.Object;
Code that I wish:
var mock = new Mock<ILogin>();
new object[,]
{
{ LoginResult.Success, "Jack", "123!##"}
, { LoginResult.WrongPassword, "Jack", "123321"}
, { LoginResult.NoSuchUser, "Peter", "123!##"}
}.ForEachRow((row) =>
{
var exprTree = (ILogin o)=>o.Login("ANY", "ANY");
AutoSetup(mock, exprTree, row); // <---- How to write this AutoSetup?
});
return mock.Object;
How to write the AutoSetup(mock, exprTree, dataArray) function above?
It takes three parameters:
mock: A mock object, e.g. new Mock()
exprTree: Expression tree that represents a method to be setup
dataArray: An object[], the 0 element is the expected result, and others are parameters that passed to the method
This was an interesting challenge. I think I have a working implementation for your AutoSetup method, using the expressions API. If anyone has a simpler solution, I'd love to see it.
static void AutoSetup<TMock, TResult>(Mock<TMock> mock, Expression<Func<TMock, TResult>> exprTree, object[] items) where TMock : class
{
var methodCallExpr = exprTree.Body as MethodCallExpression;
var arguments = items.Skip(1).Select(o => Expression.Constant(o));
var updatedMethod = methodCallExpr.Update(methodCallExpr.Object, arguments);
var updatedLambda = exprTree.Update(updatedMethod, exprTree.Parameters);
mock.Setup(updatedLambda).Returns((TResult)items[0]);
}
Here is a full working test as a console app, with an implementation of ForEachRow, which you didn't provide.
class Program
{
static void Main(string[] args)
{
var login = SetUp();
Console.WriteLine(login.Login("Jack", "123!##"));
Console.WriteLine(login.Login("Jack", "123321"));
Console.WriteLine(login.Login("Peter", "123!##"));
Console.ReadKey();
}
static ILogin SetUp()
{
var mock = new Mock<ILogin>(MockBehavior.Strict);
var rows = new object[,]
{
{ LoginResult.Success, "Jack", "123!##" },
{ LoginResult.WrongPassword, "Jack", "123321" },
{ LoginResult.NoSuchUser, "Peter", "123!##" }
};
rows.ForEachRow((row) => AutoSetup(mock, (ILogin l) => l.Login("ANY", "ANY"), row));
return mock.Object;
}
private static void AutoSetup<TMock, TResult>(Mock<TMock> mock, Expression<Func<TMock, TResult>> exprTree, object[] items) where TMock : class
{
var methodCallExpr = exprTree.Body as MethodCallExpression;
var arguments = items.Skip(1).Select(o => Expression.Constant(o));
var updatedMethod = methodCallExpr.Update(methodCallExpr.Object, arguments);
var updatedLambda = exprTree.Update(updatedMethod, exprTree.Parameters);
mock.Setup(updatedLambda).Returns((TResult)items[0]);
}
}
public static class ArrayExtensions
{
public static void ForEachRow<T>(this T[,] rows, Action<T[]> action)
{
var x = rows.GetLength(1);
var y = rows.GetLength(0);
for (int i = 0; i < y; i++)
{
var row = new T[x];
for (int j = 0; j < x; j++)
{
row[j] = rows[i, j];
}
action(row);
}
}
}
public interface ILogin
{
LoginResult Login(string p1, string p2);
}
public enum LoginResult
{
Success,
WrongPassword,
NoSuchUser
}
EDIT: You asked in a comment about how to take advantage of the variable parameter matching that Moq provides with the It.IsAny<> method. Because what you pass to your Mock.Setup() is an expression tree, it's able to scan the method parameters and implement special behaviour for any that are calls to It.IsAny<>. However, if you use It.IsAny<> in your test data array, by the time we retrieve it from your items array to set in on the expression, it's not a method call but simply the result of the call it It.IsAny<> which is default(T) (see here).
We need some way of specifying in your test data array that the parameter should be any. Then we can check for this special case and generate the correct MethodCallExpression representing a call to It.IsAny<>.
Here are the changes I made to support this:
Add an Any type to use in your test data
public class Any<T>
{
private Any() { }
public static Any<T> Param { get { return new Any<T>(); } }
}
Update the AutoSetup method to handle this special case:
private static void AutoSetup<TMock, TResult>(Mock<TMock> mock, Expression<Func<TMock, TResult>> exprTree, object[] items) where TMock : class
{
var arguments = items.Skip(1).Select(o => {
var type = o.GetType();
if (type.IsGenericType && type.GetGenericTypeDefinition() == typeof(Any<>))
{
var typeParameter = type.GetGenericArguments();
var genericItIsAny = typeof(It).GetMethod("IsAny");
var itIsAny = genericItIsAny.MakeGenericMethod(typeParameter);
return Expression.Call(itIsAny) as Expression;
}
return Expression.Constant(o);
});
var methodCallExpr = exprTree.Body as MethodCallExpression;
var updatedMethod = methodCallExpr.Update(methodCallExpr.Object, arguments);
var updatedLambda = exprTree.Update(updatedMethod, exprTree.Parameters);
mock.Setup(updatedLambda).Returns((TResult)items[0]);
}
In the test data, use the Any type
{ LoginResult.Success, "NoPasswordUser", Any<string>.Param }
Depending on how you're storing your test data, you might need another way of identifying parameters that you want to be variable (specially formatted string?), but in general this should give you an idea about how to create the correct expressions.

How can I get parameters values from a lamba expression for my nifty cache extension?

First of all it might be worth looking at this question:
How can I cache objects in ASP.NET MVC?
There some pseudo code that almost does what i want:
public class CacheExtensions
{
public static T GetOrStore<T>(this Cache cache, string key, Func<T> generator)
{
var result = cache[key];
if(result == null)
{
result = generator();
cache[key] = result;
}
return (T)result;
}
}
However, what I'd really like to do, is auto-generate the "key" from the generator. I figure i need to change the method signature to:
public static T GetOrStore<T>(this Cache cache,
System.Linq.Expressions.Expression<Func<T>> generator)
I want to use the method name, but also any parameters and their values to generate the key. I can get the method body from the expression, and the paramter names (sort of), but I have no idea how to get the paramter values...?
Or am I going about this the wrong way? Any ideas much appreciated.
Here's how I did it:
public static class ICacheExtensions
{
public static T GetOrAdd<T>(this ICache cache, Expression<Func<T>> getterExp)
{
var key = BuildCacheKey<T>(getterExp);
return cache.GetOrAdd(key, () => getterExp.Compile().Invoke());
}
private static string BuildCacheKey<T>(Expression<Func<T>> getterExp)
{
var body = getterExp.Body;
var methodCall = body as MethodCallExpression;
if (methodCall == null)
{
throw new NotSupportedException("The getterExp must be a MethodCallExpression");
}
var typeName = methodCall.Method.DeclaringType.FullName;
var methodName = methodCall.Method.Name;
var arguments = methodCall.Arguments
.Select(a => ExpressionHelper.Evaluate(a))
.ToArray();
return String.Format("{0}_{1}_{2}",
typeName,
methodName,
String.Join("|", arguments));
}
}
with this helper to evaluate nodes of an expression tree:
internal static class ExpressionHelper
{
public static object Evaluate(Expression e)
{
Type type = e.Type;
if (e.NodeType == ExpressionType.Convert)
{
var u = (UnaryExpression)e;
if (TypeHelper.GetNonNullableType(u.Operand.Type) == TypeHelper.GetNonNullableType(type))
{
e = ((UnaryExpression)e).Operand;
}
}
if (e.NodeType == ExpressionType.Constant)
{
if (e.Type == type)
{
return ((ConstantExpression)e).Value;
}
else if (TypeHelper.GetNonNullableType(e.Type) == TypeHelper.GetNonNullableType(type))
{
return ((ConstantExpression)e).Value;
}
}
var me = e as MemberExpression;
if (me != null)
{
var ce = me.Expression as ConstantExpression;
if (ce != null)
{
return me.Member.GetValue(ce.Value);
}
}
if (type.IsValueType)
{
e = Expression.Convert(e, typeof(object));
}
Expression<Func<object>> lambda = Expression.Lambda<Func<object>>(e);
Func<object> fn = lambda.Compile();
return fn();
}
}
When calling a function that produces a collection i want to cache i pass all my function's parameters and function name to the cache function which creates a key from it.
All my classes implement an interface that has and ID field so i can use it in my cache keys.
I'm sure there's a nicer way but somehow i gotta sleep at times too.
I also pass 1 or more keywords that i can use to invalidate related collections.
