• ASP.NET MVC 3 NOT showing appropriate view, action called using jquery

  - by TunAntun

  I have a small problem. My action is : public ViewResult SearchForRooms(int HotelDDL) { List<Room> roomsInHotel = bl.ReturnRoomsPerHotel(HotelDDL); return View(roomsInHotel); } Here is the jquery that is calling the action: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#HotelDDL").change(function () { var text = $("#HotelDDL option:selected").text(); var value = $("#HotelDDL option:selected").val(); alert("Selected text=" + text + " Selected value= " + value); $.post("/Home/SearchForRooms", { HotelDDL: $("#HotelDDL option:selected").val() }); }); }); </script> And finally, here is the View that should be called: @model IEnumerable<RoomReservation.Entities.Entities.Room> @{ ViewBag.Title = "Search"; } <h2>Result</h2> <table> <tr> <th> City </th> <th> Hotel </th> <th> Room label </th> <th> Number of beds </th> <th> Price per night </th> <th></th> </tr> @foreach (var item in Model) { <tr> <td> @Html.DisplayFor(modelitem=>item.Hotel.City.Name) </td> <td> @Html.DisplayFor(modelItem => item.Hotel.Name) </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> <td> @Html.DisplayFor(modelItem => item.NumberOfBeds) </td> <td> @Html.DisplayFor(modelItem => item.PricePerNight) </td> </tr> } </table> Everthing is working ok (databse return all rooms correctly) except final view rendering. I have tried Phil's tool but it doesn't give me any suspicious hints: RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); So, why is it not showing after jscript send it's post method to SearchForRooms()? Thank you P.S. If you need any other piece of code please just say so.

• Are there any open source C# libraries for binding the properties from one class to another?

  - by Jason Slocomb

  I don't remember which blog I was reading, because it seemed academic at the time, but there was a library being discussed where you could take a two concrete classes and bind the properties together if the names matched. Think ASP.NET MVC model binding.

• Hint to MVC view generator for primary key on POCOs

  - by myotherme

  When generating a strongly-typed Index view for my model I always get the following: <%= Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) %> I am using a POCO class for use with our ORM. As I understand it when using LINQ to SQL the view code will know which field is the primary key. Is there a way that I can an attribute to the property (or class) that will let the View Generator know that the ID property if the primary key?

• Polymorphic association inserts 0 instead of raising error when column is misconfigured as Integer

  - by zetetic

  Here's one that stumped me for a while, though in retrospect it should have been obvious. I was getting the error message NoMethodError: undefined method `constantize' for 0:Fixnum when accessing a model through a polymorphic association. Turns out the table on the belongs_to side of the association had an integer type column instead of a string. Easily fixed, but it seems like Rails ought to raise an error in this situation -- instead it happily adds the row with 0 in the type column.

• Django modelform ForeignKey List

  - by Harry

  How do you get each item in the ForeignKey field in a list, for example: class Delegate(models.Model): excursion = models.ForeignKey(Excursion, limit_choices_to = {'is_activity': False}, related_name='excursion', null=True, blank=True) Template: {% for object in formset.excursion_set.all %} {{ object.lable }} etc {% endfor %} My reason is that I don't want the options to display as a dropdown, but in a custom way that I will style etc.

  - by xRobot

• How to get password html helper to render password on failed validation

  - by Max Schmeling

  I have a form for creating a new account and it has a password field in it. I'm using view models to pass data to the controller action and back to the form view. When the user enters their details in, and clicks submit, if validation fails and it returns them to the same view passing back in the view model, it won't default the password to what they entered. How can I get it to do this? Or should I even try?

• How do I make non-framework code to framework code? (PHP)

  - by ggfan

  I just started using CakePHP and it's very different from just normal procedural or basic OOP PHP. I am still learning PHP and still read "beginning PHP/mysql" books that teaches you basic PHP. Also lots of sites online provide code that isn't for a framework. Is the only way to make non-framework code to say a framework, say cakePHP, by learning cakePHP thoroughly than rewriting the code yourself to fit the MVC model?

• Java Swing - Adding a row # column to a JTable

  - by llm

  I have data from a database loaded into a JTable through a custom table model. I want to have a column (should be the first column) which simply shows the display row number (i.e. it is not tied to any data (or sorting) but is simply the row number on the screen starting at 1). These "column headers" should be grayed out like the row headers. Any idea how to do this? Thanks

• How to I make a navigation-based app?

  - by Dyldo42

  Yes, I know, most of you are thinking I'm an idiot, butt (kidding) I'm not. I've been searching everywhere for something on how to fully make a navigation-based iphone app, but all I've found is how to set up table views or navigation controllers. I haven't found anything on how to create a data model (something simple from arrays and dictionaries, SQLite and CoreData are a bit out of my scope) or navigate it. Does anyone know of any tutorials or anything like that? Thanks.
