Error Resolution : [ng:areq] Argument 'fn' is not a function, got string in angular js

Error: [ng:areq] Argument 'fn' is not a function, got string

I confronted an error which is shown above during Angular application development which was little tricky to resolve.Though later we could be able to identify an issue  and fix an issue.

At time of module loading in angular we were injecting dependancy like this:

var routingApp = angular.module('routingApp', ['ngRoute'], ['ui.bootstrap']);

Actually this is a wrong way to do ,due to this it was prompting an error

Resolution : The workaround is given below as inject a dependancy in same braket rather in different one.

var routingApp = angular.module('routingApp', ['ngRoute', 'ui.bootstrap']);

Hope it will give you some brief to fix your solution

Thanks

If you want to access the ModelState property in the View , you can use the ModelState in your Razor View as depicted below in image:

This is the source code as shown below:

2. @{ 
3.     ViewBag.Title = "Verify"; 
5. if (@ViewContext.ViewData.ModelState.IsValid) 
6.     { 
7.         ViewBag.Title = "Verify"; 
9. if (TempData["EmployeeRegistration"] != null)

Validation failed for one or more entities. See EntityValidationErrors property for more details.

Validation failed for one or more entities. See EntityValidationErrors property for more details.

Today I encountered an error during data insertion through Entity Framework as per the Title.

There could be a various cause of such issue .Here I am talking about one of them.In database I restricted Name column data Type to nvarchar(10).

 and I was inserting value which has more than 10 character.

As soon as I try to insert value it generates me an error as depicted below:

.

I have used the code as shown below to identify the root cause.

  1: public ActionResult Create(EmpRegistration collection)
  2:         {
  3:             try
  4:             {
  5:                
  6:             }
  7:             catch (System.Data.Entity.Validation.DbEntityValidationException dbEx)
  8:             {
  9:                 Exception raise = dbEx;
 10:                 foreach (var validationErrors in dbEx.EntityValidationErrors)
 11:                 {
 12:                     foreach (var validationError in validationErrors.ValidationErrors)
 13:                     {
 14:                         string message = string.Format("{0}:{1}",
 15:                             validationErrors.Entry.Entity.ToString(),
 16:                             validationError.ErrorMessage);
 17:                         // raise a new exception nesting
 18:                         // the current instance as InnerException
 19:                         raise = new InvalidOperationException(message, raise);
 20:                     }
 21:                 }
 22:                 throw raise;
 23:             }
 24:         }

This code  help you to trace exact error.The way it suggested to me that “The field Name must be a string or array type with a maximum length of '10'.”







This is the complete code which runs perfectly as shown below .I wish this code will help you sometime.

  1: public ActionResult Create(EmpRegistration collection)
  2:         {
  3:             try
  4:             {
  5:                 if (ModelState.IsValid)
  6:                 {
  7:                     EmpRegistration empRegis = new EmpRegistration();
  8:                     // TODO: Add insert logic here
  9:                     empRegis.Address = collection.Address;
 10:                     empRegis.City = collection.City;
 11:                     empRegis.Id = 7;
 12:                     empRegis.Name = collection.Name;
 13:                     objEnity.EmpRegistrations.Add(empRegis);
 14:                     objEnity.SaveChanges();
 15: 
 16:                     return View();
 17:                 }
 18:                 return View(objEnity.EmpRegistrations);
 19:             }
 20:             catch (System.Data.Entity.Validation.DbEntityValidationException dbEx)
 21:             {
 22:                 Exception raise = dbEx;
 23:                 foreach (var validationErrors in dbEx.EntityValidationErrors)
 24:                 {
 25:                     foreach (var validationError in validationErrors.ValidationErrors)
 26:                     {
 27:                         string message = string.Format("{0}:{1}",
 28:                             validationErrors.Entry.Entity.ToString(),
 29:                             validationError.ErrorMessage);
 30:                         // raise a new exception nesting
 31:                         // the current instance as InnerException
 32:                         raise = new InvalidOperationException(message, raise);
 33:                     }
 34:                 }
 35:                 throw raise;

Could not be loaded because it has a parameter or return type of type System.ServiceModel.Channels.Message in WCF

Could not be loaded because it has a parameter or return type of type System.ServiceModel.Channels.Message in WCF
 

During an implementation of WCF Operation Contract I encountered an error as per the Title.
I was returning wrong parameter value from Operation contract which takes Message Contract as parameter .Kindly refer an image to understand real fact.
 

 
There are some limitation which are listed below,which we should keep in mind during implementation of WCF service

You can use the Message class as an input parameter of an operation, the return value of an operation, or both. If Message is used anywhere in an operation, the following restrictions apply:

• The operation cannot have any out or ref parameters.
  
• There cannot be more than one input parameter. If the parameter is present, it must be either Message or a message contract type.
  
• The return type must be either void, Message, or a message contract type

Hope it will help you sometime.
