With .net 4.0/Preview kit 2, we can generate help pages for WCF REST.
Is there anyway we can do the same for MVC ?
www.somewebsite.com/search/help
I can create help pages (views) and expose them.
I can generate XSD schema and spit out as xml.
Any other guidance/suggestions ?
I want to generate something similar to this.
UriTemplate http://somewebsite.com/Search/
Method PUT
Response Format Xml
Response Schema http://somewebsite.com/help/response/schema
Response Example http://somewebsite.com/help/response/example
Update:
I was able to create documentation by using below code.
Route : somewebsite.com/Media/
HelpRoute : somewebsite.com/Media/Help (Append help to the parent route)
Add routes accordingly. See below example.
routes.MapRoute("Search",
"Search/Quick/",
new { controller = "Search", action = "Search" },
new { httpMethod = new HttpMethodConstraint("PUT") }
);
routes.MapRoute("SearchHelp",
"Search/Quick/Help",
new { controller = "Search", action = "Search" },

This code is not bug free. Please post improvements if you have any. Use it at your own risk.
Not exactly sure what you are looking for, but you can check out GhostDoc:

I use this to generate XML documentation in MVC.
Most probably you have solved your issue by now. Anyway, I think you need IApiExplorer. Have a look at this blog.

I allready look out everything of that problem but none of them worked for me.Everyone is suggestion to use AsNoTracking() for that problem but its has no sense with my problem because im not updating the data which i call from my database.
I have company profile update modal, this company can have profile photo or not but either way i need to update those informations. So that's why i need to control is comapny creating a photo or updating a photo. Let me show u to my code in the bellow :
#region /*UpdateCompanyProfile*/
[HttpPost]
public IActionResult UpdateCompanyProfile(Company company, List<IFormFile> files, int FileID)
{
try
{
if (ModelState.IsValid)
{
company.ModifiedDate = DateTime.Now;
_unitOfWorkC.RepositoryCompany.Update(company);
int firstRequest = HttpContext.Response.StatusCode;
if (firstRequest == 200)
{
_unitOfWorkC.Complete();
if (files.Count != 0)
{
var File = _fileUploader.FileUploadToDatabase(files);
var FileResult = File.Result;
FileResult.CompanyID = company.CompanyID;
if (FileID == 0)//That's the point where i control that file, is it gonna be update or create.
{
_unitOfWorkFR.RepositoryFileRepo.Create(FileResult);
int secondRequest1 = HttpContext.Response.StatusCode;
if (secondRequest1 == 200)
{
int tryCatch = _unitOfWorkFR.Complete();
if (tryCatch != 15)
{
TempData["JS"] = "showSuccess();";
}
else
{
TempData["JS"] = "showError();";
}
}
}
else
{
FileResult.FileID = FileID;
_unitOfWorkFR.RepositoryFileRepo.Update(FileResult); //That's the point where i get the error.
int secondRequest2 = HttpContext.Response.StatusCode;
if (secondRequest2 == 200)
{
int tryCatch2 = _unitOfWorkFR.Complete();
if (tryCatch2 != 15)
{
TempData["JS"] = "showSuccess();";
}
else
{
TempData["JS"] = "showError();";
}
}
else
{
TempData["JS"] = "showError();";
}
}
}
}
else
{
TempData["Message"] = "?irket g?ncelleme i?leminiz ba?ar?s?z!";
TempData["JS"] = "showError();";
return RedirectToAction("CompanyProfile");
}
}
else
{
TempData["Message"] = "G??ncellemek istedi?iniz veri hatal?!";
TempData["JS"] = "showError();";
return RedirectToAction("CompanyProfile");
}
}
catch (Exception ex)
{
var log = _logging.Logging(ex.Message, "Exception/Hata", company.CompanyID.ToString(),
"CompanyProfile/UpdateCompanyProfile", getCurrentUser(), getCurrentUserClaimRole());
_unitOfWorkLog.RepositoryLog.Create(log);
_unitOfWorkLog.Complete();
//TempData["Message"] = ex.Message;
//TempData["JS"] = "showError();";
return RedirectToAction("CompanyProfile");
}
}

As u can see, calling that data with AsNoTracking() has no sense in my stuation. I'm only getting that error in that action,so other FileRepo actions are working well.
That's my FileUploadToDatabase() method :
public async Task<FileRepo> FileUploadToDatabase(List<IFormFile> files)
{
foreach (var file in files)
{
var fileName = Path.GetFileNameWithoutExtension(file.FileName);
var fileExtension = Path.GetExtension(file.FileName);
_fileRepo = new FileRepo
{
FileName = fileName,
FileExtension = fileExtension,
FileType = file.ContentType,
CreatedDate= DateTime.Now
};
using (var dataStream = new MemoryStream())
{
await file.CopyToAsync(dataStream);
_fileRepo.FileData = dataStream.ToArray();
}
}
return _fileRepo;
}
And that's my FileRepo class :
public class FileRepo : Base
{
[Key]
public int FileID { get; set; }
[Required(ErrorMessage = "Required Field !")]
public string FileName { get; set; }
[Required(ErrorMessage = "Required Field !")]
public string FileType { get; set; }
[Required(ErrorMessage = "Required Field !")]
public string FileExtension { get; set; }
public string FilePath { get; set; }
public bool FilePhotoIsDefault { get; set; }
public byte[] FileData { get; set; }
public int? CompanyID { get; set; }
public Company Company { get; set; }
#endregion
}
That's my UnitOfWork :
and This is my Repository :
This is the query for my Update Modal:
public IEnumerable<Company> GetByIDForCompanyProfileCompany(int ID)
{
return TradeTurkDBContext.Companies.Where(x => x.CompanyID == ID)
.Include(x => x.Addresses.Where(x => x.IsDeleted == null || x.IsDeleted == false))
//
.Include(x => x.Products.Where(x => x.IsDeleted == null || x.IsDeleted == false))
.ThenInclude(x => x.FileRepos.Where(x => x.IsDeleted == null || x.IsDeleted == false)).AsSplitQuery()
//
.AsNoTrackingWithIdentityResolution().ToList();
}
For updating FileResult you are using DbSet.Update - it is trying to attach entity to ChangeTracker. Attaching will fail if there is already attached object with the same key.
Change your repository to the following. It will update all fields if entity is not in ChangeTracker, otherwise it will correct only needed properties:
public void Update(T model)
{
if (model == null)
throw new ArgumentNullException(nameof(model));
// I hope your generic repository knows Model Id property
var entry = _context.ChangeTracker.Entries<T>().FirstOrDefault(e => e.Entity.Id == model.Id);
if (entry == null)
{
// entity not tracked, so attach it
_dbSet.Update(model);
}
else
{
// setting values from not tracked object
if (!ReferenceEquals(model, entry.Entity))
entry.CurrentValues.SetValues(model);
}
}
UPDATE
If generic repository don't know about Id property, you can define interface for that:
public interface IEntityWithId
{
int Id {get;}
}
Make sure that your classes is implementation of IEntityWithId. Then correct Repository definition:
public interface IRepository<T> where T: class, IEntityWithId
{
...
}

I want to do something like:
var jsonData = jsonObject
return View("myHTMLpage", jsonData);
How to do it with ASP.NET MVC ?
You can create custom ActionResult as JsonNetResult
public class JsonNetResult : ActionResult
{
public Encoding ContentEncoding { get; set; }
public string ContentType { get; set; }
public object Data { get; set; }
public JsonSerializerSettings SerializerSettings { get; set; }
public Formatting Formatting { get; set; }
public JsonNetResult() {
SerializerSettings = new JsonSerializerSettings();
}
public override void ExecuteResult( ControllerContext context ) {
if ( context == null )
throw new ArgumentNullException( "context" );
HttpResponseBase response = context.HttpContext.Response;
response.ContentType = !string.IsNullOrEmpty( ContentType )
? ContentType
: "application/json";
if ( ContentEncoding != null )
response.ContentEncoding = ContentEncoding;
if ( Data != null ) {
JsonTextWriter writer = new JsonTextWriter( response.Output ) { Formatting = Formatting };
JsonSerializer serializer = JsonSerializer.Create( SerializerSettings );
serializer.Serialize( writer, Data );
writer.Flush();
}
}
}

The controller writes a message. But if you write a message (through a POST request) on a bulletin board, it will work normally when you try to post it the first time. But when you try to post again, it fails. I think the cause is a duplicate primary key.
Please let me know what you can do in case of a duplication of the primary key.

public class ArticlesEditViewModel

public Articles Article { get; set; }
public List<ArticleFiles> Files { get; set; }

I am new to nopcommerce plugin development but am learning very fast.
I am developing a widget plugin to display vendor information box in product details page, but am having some issues, the product page stopped displaying and throwing errors.
Below and in this question will be my codes and picture of the product page error.
Contoller:
[ChildActionOnly]
public ActionResult PublicInfo(string widgetZone, Vendor vm, object additionalData)
{
ActionResult actionResult;
EmptyResult emptyResult = new EmptyResult();
var activeStoreScopeConfiguration = this.GetActiveStoreScopeConfiguration(this._storeService, this._workContext);
VendorDetailsSettings VendorDetailsSetting = _settingService.LoadSetting<VendorDetailsSettings>(activeStoreScopeConfiguration);
if (VendorDetailsSetting != null)
{
int QproductId = Convert.ToInt32(System.Web.HttpContext.Current.Request.RequestContext.RouteData.Values["productId"]);
var productId = Convert.ToInt32(additionalData);
if (productId != 0)
{
Product productById = _productService.GetProductById(productId);
if (productById == null ? false : productById.VendorId != 0)
{
Vendor vendorById = _vendorService.GetVendorById(productById.VendorId);

Model.Description = LocalizationExtensions.GetLocalized<Vendor>(vendorById, Expression.Lambda<Func<Vendor, string>>(Expression.Property(parameterExpression, (MethodInfo)MethodBase.GetMethodFromHandle(typeof(Vendor).GetMethod("Description").MethodHandle)), new ParameterExpression[] { parameterExpression }));

actionResult = emptyResult;
}
}
else

actionResult = emptyResult;
}
}
else
{
actionResult = emptyResult;
}
return actionResult;
}
Plugin.cs:
public IList<string> GetWidgetZones()
{
return string.IsNullOrEmpty(_vendorDetailsSettings.WidgetZone) ? new List<string>() : new List<string> { _vendorDetailsSettings.WidgetZone };
}
public void GetConfigurationRoute(out string actionName, out string controllerName, out RouteValueDictionary routeValues)
{
actionName = "Configure";
controllerName = "WidgetsVendorDetails";
routeValues = new RouteValueDictionary { { "Namespaces", "Nop.Plugin.Widgets.VendorDetails.Controllers" }, { "area", null } };
}
/// <summary>

public void GetDisplayWidgetRoute(string widgetZone, out string actionName, out string controllerName, out RouteValueDictionary routeValues)
{
actionName = "PublicInfo";
controllerName = "WidgetsVendoDetails";
routeValues = new RouteValueDictionary
{
{"Namespaces", "Nop.Plugin.Widgets.VendorDetails.Controllers"},

{"widgetZone", widgetZone}
};
}
public override void Install()
{
var settings = new VendorDetailsSettings
{
WidgetZone = "productbox_add_info"
};
_settingService.SaveSetting(settings);
base.Install();
}
public override void Uninstall()
{
_settingService.DeleteSetting<VendorDetailsSettings>();
base.Uninstall();
}
}
The error was the product page didn't implement IControllers... But I have resolved it.. By Returning base. View() instead or just views...
Thanks.
I'm trying to implement client validation for my custom type, however i'm not sure how to do it for min/max validators.
model:
[MultilanguagePropertyRequired(ErrorMessageResourceName = "fld_Description_val_Required", ErrorMessageResourceType = typeof(Resources.Service.Controllers.Firm))]
[MultilanguagePropertyStringLength(1000, MinimumLength = 150, ErrorMessageResourceName = "fld_Description_val_MinLength_lbl", ErrorMessageResourceType = typeof(Resources.Service.Controllers.Firm))]
[Display(Name = "fld_Description_lbl", ResourceType = typeof(Resources.Service.Controllers.Firm))]
public MultilanguageProperty<string> Description
{
get
{
return this.GetMultilanguageProperty("Description", string.Empty, this);
}
set
{
this.SetMultilanguageProperty("Description", value);
}
}
this is my custom string length attribute that extends "StringLegth":
[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, AllowMultiple = true)]
public class MultilanguagePropertyStringLengthAttribute : StringLengthAttribute, IClientValidatable
{
public MultilanguagePropertyStringLengthAttribute(int length) : base(length)
{
}
public override bool IsValid(object value)
{
string strValue = (string)(value as MultilanguageProperty<string>).Value;
return base.IsValid(strValue);
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
yield return new ModelClientValidationRule() { ValidationType = "multilanguagestringlength", ErrorMessage = this.ErrorMessageString };
}
}
then on my view I have this:
..
<script type="text/javascript">
(function ($) {
$.validator.unobtrusive.adapters.addBool("multilanguagerequired", "required");
$.validator.unobtrusive.adapters.addMinMax("multilanguagestringlength", "minlength", "maxlength");
} (jQuery));
</script>
..
which doesn't work. am i missing something here?
thanks
No need to have a custom client side validation. You can try something like this:
[AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = false, Inherited = true)]
public sealed class ValidatePasswordLengthAttribute : ValidationAttribute, IClientValidatable {
private const string _defaultErrorMessage = "'{0}' must be between {1} and {2} characters long.";
private readonly int _minCharacters, _maxCharacters;
public ValidatePasswordLengthAttribute(int minLength, int maxLength)
: base(_defaultErrorMessage) {
_minCharacters = minLength;
_maxCharacters = maxLength;
}
public override string FormatErrorMessage(string name) {
return String.Format(CultureInfo.CurrentCulture, ErrorMessageString,
name, _minCharacters, _maxCharacters);
}
public override bool IsValid(object value) {
string valueAsString = value as string;
return (valueAsString != null && valueAsString.Length >= _minCharacters && valueAsString.Length <= _maxCharacters);
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) {
return new[]{
new ModelClientValidationStringLengthRule(FormatErrorMessage(metadata.GetDisplayName()), _minCharacters, _maxCharacters)
};
}
}
It comes from the build-in MVC3 internet project template.
I am solving similar problem in a different way, but hey, try some parts of this code! I mean GetClientValidationRules() method for string length validation.
public sealed class MyStringLengthAttribute : StringLengthAttribute, IClientValidatable
{
private int? labelId;
public MyStringLengthAttribute(int label, int maximumLength)
: base(maximumLength)
{
labelId = label;
}
public override string FormatErrorMessage(string name)
{
if (labelId.HasValue)
{
return String.Format(MyLabel.Label(labelId.Value), name);
}
return String.Format(MyLabel.Default("FieldTooLong_Validation", "Field {0} is too long"), name);
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
StringLengthAttributeAdapter adapt = new StringLengthAttributeAdapter(metadata,context, this);
return adapt.GetClientValidationRules();
}
}
I use the Adapter class I found in .NET framework, and no need for the custom Javascript work.
And follow this if you still want to do custom JS part http://itmeze.com/2010/12/06/checkbox-has-to-be-checked-with-unobtrusive-jquery-validation-and-asp-net-mvc-3/
I too am having the same problem. You are missing ValidationParameters in your GetClientValidationRules:
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
var rule = new ModelClientValidationRule
{
ErrorMessage = this.ErrorMessage,
ValidationType = "dayrange"
};
rule.ValidationParameters.Add("min", _minimumDays);
rule.ValidationParameters.Add("max", _maximumDays);
yield return rule;
}
I still having problems with the wiring between the jQuery.validator and jQuery.validator.unobtrusive.adapters but here's the code. Hope it helps:
$(function () {
jQuery.validator.addMethod('dayRange', function (value, element, param) {
if (!value) return false;
var valueDateParts = value.split(param.seperator);
var minDate = new Date();
var maxDate = new Date();
var now = new Date();
var dateValue = new Date(valueDateParts[2],
(valueDateParts[1] - 1),
valueDateParts[0],
now.getHours(),
now.getMinutes(),
(now.getSeconds()+5));
minDate.setDate(minDate.getDate() - parseInt(param.min));
maxDate.setDate(maxDate.getDate() + parseInt(param.max));
return dateValue >= minDate && dateValue <= maxDate;
});
jQuery.validator.unobtrusive.adapters.addMinMax('dayrange', 'minlength', 'maxlength', 'dayrange');
}(jQuery));
