Create Code To Generate DB From Domain Model

Mar 27, 2011

Out of good design practice and organization, in which project should a local development SQL database be in a web based application? I'm just starting my assignment so I currently have 'CompanyName.Web.UI' and 'CompanyName.Domain' projects setup. Im using LinqToSql and creating my database from POCOS, meaning I'll have to create some code to generate the DB from my domain model. I.e.

DataContext dc = new DataContext(connString);
dc.GetTable<TableType>();
dc.CreateDatabase();

Nov 26, 2010

How to generate a path/url from a Route in the Routes table? only this time I'd like to be able to build a url within one of my Model (partial) classes.

I found the UrlHelper.GenerateUrl method, but get unstuck once I get beyond passing in the appropriate RouteName, ActionName and ControllerName.

Automatically Generate Buddy Classes From Model In C#

Apr 28, 2010

I use Linq to Sql (although this is equally applicable in Entity Framework) for my models, and I'm finding myself creating buddy classes for my models all the time. I find this time consuming and repetitive. Is there an easy way to automatically generate these buddy classes based on the models? Perhaps a visual studio macro?

[MetadataType(typeof(PersonMetadata))]
public partial class Person
{
}
public class PersonMetadata
{
public object Id { get; set; }

MVC :: Generate Proper Controls In View Based On The Model

Jan 24, 2011

it is possible to customize the typed view generation process to generate the proper controls based on the fields annotations of a model. For Example I have a Person Model that contains Foreign Keys like CityID,DepartmentID etc. So When i generate a view againt the Person Model it creates textbox's for all the Person fields but i want dropdownlists against FK fields. It Should be smart enough to at least geereate the peroper controls based on the Person's field annotations. How can i acheive that? Has anybody worked on that?

MVC :: Store Model In Separate Class Library- Pass Model Objects?

May 19, 2010

I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.

When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?

The type or namespace name '' could not be found (are you missing a using directive or an assembly reference?)

HttpHandlers / Modules :: Process Model Or Thread Model Of A Website?

Mar 11, 2010

I have an issue of static variable in an asp.net application. Let's say I have a server with 8 CPUs running windows 2008 R2 hosting an asp.net webbsite, nothing fancy here, no funny configuration.

Is the following statement true? at any single time, there's one and only one process is running and accepting requests, even in the recycling stage. The reason I am asking is: I have a static field in my class, and I want to make that's the only static instance in the website. I've heard in some circumstances, IIS is recylcing your application, and it will start a new process, but the old process is still working, thus I will have 2 static instances in memory, which defeat the purpose of static field.

One step further, let's assume there might be 2 instances in memory, can I assume there are at most 2 instances at any single time? And can I assume once the second instance is up, the first instance will NEVER accept new requests?

Another question: Recently I have a problem with an applicationdomain concept. Looks like if an application domain causes a memory leak, unload the domain will not release the memory (Umanaged leak). So to what extent Application Domain is isolated?

Default Model Binder Does Not Bind Model Class

Dec 28, 2010

I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted

<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>

This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });

This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }

But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.

MVC :: Model State Doesn't Contain Model Values

Aug 2, 2010

when I use Html.HiddenFor( model => model.OwnerId ) to create a hidden field, the value assigned to that field is zero. When I use <input type="hidden" value="<%: Model.OwnerId %>" /> to add the hidden field to the form, the value is assigned correctly.

Why would Html.HiddenFor( model => model.OwnerId ) not get the correct value from the Model object? Am I supposed to load model state somehow separate from returning the model object from the action method? Here is the view:

[Code]....

The Create action method is relatively straight forward.

public ActionResult Create( ... )
{
ViewStockItem item = new ViewStockItem();
item.ActionCode = ActionCode.Add;
if (item.OwnerId == 0)
item.OwnerId = 7;
BookOwner owner = db.BookOwners.Single(c => c.OwnerId == item.OwnerId);
item.OwnerName = owner.OwnerName;
return View(item);
}

Should Data Annotations Be On The Model Or The View Model

Dec 15, 2010

I've been used to decorating data model classes with data annotation attributes, but the purist in me baulks slightly at including purely presentational attributes such as display format here. I am, however, quite happy to keep validation centric attributes here. One good reason I have to continue keeping all annotations etc. in the data model is that my view model aggregates data model classes, e.g.

my ViewModelBase.DetailItem<TEntity> property in the view model is just a reference to an entity class in my data model. If I wanted to move presentational annotations to the view model, I would have to quite radically revise my design to one where I duplicate data model properties in my view model and use an object mapping tool to populate view model objects based on data model objects.

MVC :: View Model To Convert To Domain Model?

May 4, 2010

Say I got a domain model as follows: (and my repository expect an instance of this object)

[Code]....

And a view model (which my views are based on)

[Code]....

At the moment I got it like this and have my controller action manually create a new Person object from the PersonModel object before passing it on to the repository, which does not feel right.

So I tried to have PersonModel inherit from Person and pass that to the repository (also tried casting the PersonModel to a Person object first), but that don't work out.

What's the right way to have PersonModel automatically cast to Person? I want to keep this logic as my current structure allow me to keep things really loosely coupled, with the repository layer not having a clue how it's being used.

MVC :: Validation Of Model In Side Model

Oct 12, 2010

I have recently started working on ASP.NET with MVC 2 framework, and I am facing following difficulty in validating my data,

Scenario:

In my application the view (ASPX) is divided into tabs (jQuery) and each tab's content is ViewUserControl (ASCX). The main model for the view has collection of sub models for individual tabs. I use RenderPartial method to render view user control.

[Code]....

And the user control (Tab1.ascx) refers the specific model for it,

[Code]....

Now if in my Tab1Model if I put following validation

[Code]....

In the controller ModelState.IsValid is always indicates TRUE. How do I override the validation behavior such that it as well looks the items in the collection member (which holds sub models) as well.

<%= Html.ValidationMessage("FirstName") %>

Visual Studio :: What Is The Difference Between "Website Application Model" And The "Web Project Application Model"

Aug 28, 2009

The App_Code folder should only be used when managing your project through the Website Project Model. If you are using the Web Application Project Model, create a standard folder and add the classes to that. For example, you could add a new folder named Classes, and place your code there."

What is the difference between the "Website Application model" and the "Web Project Application model" they sound very similar. It actually sounds like two ways to say the same thing. Is the Website application model from Web Developer express?

I am using VS 2008 Pro. When I create a new project I select create Project from the start page. I then choose the "ASP.net web application" as the type of project from the "Visual Studio Installed Templates". It seems like I am using the "Web Project Application model

Dynamically Generate URL?

Dec 26, 2009

I have a .NET developer working on a web application for me. Basically, the brief was to produce a site which operates a bit like BaseCamp, whereby users register and their usernames are incorporated into the URL of the site for their sub-account holders to log in.E.g. a master account holder registers at [URL] with the username 'dave'. Dave can then send a link to his clients where they can register. The link Dave sends out to his clients to log-in is: [URL] [URL] Basecamp does this but they do it via sub-domains rather than folders at the end of the url (e.g. [url] - I'm keener to use folders as non-techy people (who this is aimed at) could find sub-domains a bit confusing. I thought it would be straight foward to get .NET to generate these URLs dynamically from the database.Anyhow, my developer tells me that it's absolutely not possible to generate the URLs without hard-creating folders in the filesystem and using redirects within those folders to redirect to a generic log-in page with a querystring variable. To me this is a very messy solution. I could do this myself in classic ASP, one of the reasons I have employed a .NET developer, as having used .NET CMS systems like Umbraco this is how they work. It must be possible. Can anyone confirm the situation with this? Is it possible to do in .NET? Would it be a hugely difficult task?

I am working on a tool to construct a diagram in asp.net .The user is allowed to select the images from panel [generated dynamically based on user input in dropdown box] and its copy should be created on the diagram area, it should be draggable and should over lay with each other . So far I am able to create the diagram objects dynamically and on click on each object its copy will be created on the diagram area [I am passing the instance from user control to main page] . I have used Drag Drop Extender to apply Drag behavior. Now my problem is which I create more objects the position of already created objects is not retained in the page. I have js code to retain the position for static controls, but dont know how to apply for dynamic controls.

Im looking for ideas for generating RSS feeds in the best way for many feeds. I would have so many RSS feeds and even users will have their own feeds (a custom hitlist/search result page if you want), that making a file for each isnt something I want (both from a security point and the mess it could be if you would move the installation etc.). The option is to make a .aspx file output the hitlist, but I assume RSS readers will poll that list very heavily? Would it be best to just store the hitlist in a blob and only output that entirly?

How To Generate And Consume Xml In C#

Apr 28, 2010

i have not worked with XML in a while can someone post the syntax needed to build and save an xml node structure that resembles that of a tree structure that is created by a recursive function.

basically i have a recursive function that saves data found an a page(url) and then follows each URL found on that page recursivley and does the same to it. to audit this i want an output as a xml file to disk so i can see how it is doing its recursion and parsing.

the code i have is below. please add to it the needed xml calls needed to create a xml structure like the one i show below. (please include the full name space so i can see where the objects i need in .net are for this.)

page1.htm has 2 links on it:

<a href=page1_1.htm>
<a href=page1_2.htm>

page1_1.htm has 2 links on it

<a href=page1_1_a.htm> (this then will have some links also)
<a href=page1_1_b.htm> (this then will have no more links on it - dead end)

the xml should do something like this:

<node url=page1.htm>
...<node url=page1_1_a.htm>
...... <node url="xxx.htm"/>
...... <node url="yyy.htm".>
... </node>
...<node url=page1_1_b.htm />
