There is only one problem I have with this: Model validation shows error message on [Range(1, 100, ErrorMessage = "Price must be between $1 and $100")] methods_de was fixing the decimal comma issue before, but now that range check have problem with it. Cheers.

However, the big problem with "drop and recreate" is that eventually, applications go into production. It's far too easy to forget that this "developer short-cut" is in the code, and needs to be removed. It's much better to teach people the right way first, even if it adds a page to the tutorial.

[DisplayFormat(DataType.Date)]

instead of:

[DataType(DataType.Date)]

I'm having an issue with fields I do NOT want to be required. I excluded the Required attribute from ReleaseDate, but a validation error is still thrown. Any insight would be greatly appreciated.

To make the ReleaseDate optional, make it nullable by adding a question mark after the type (public DateTime? ReleaseDate...). This causes "Allow Null" to be True in the generated DB column.

[DisplayFormat(DataFormatString = "{0:c}", HtmlEncode=false)]

[Required(ErrorMessage = "Price missing")]

[Range(1, 100, ErrorMessage = "Price must be between 1 and 100")]

public decimal Price { get; set; }

The proceeding code does not allow input of commas which is used as decimal point for foreign currencies.

if I enter 9,99 it gives --> the price must be a number.

then if I enter 9.99 it gives --> 9.99 is not valid for price.

So, any way to solve this problem in Edit and in Create ?

Without Range it works fine using the method_de.js file with this and this in the Views/Movies/Create.cshtml file:

4. Add a reference to the script after the two other script references in the Views/Movies/Create.cshtml file:

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

<script src="@Url.Content("~/Scripts/methods_de.js")" type="text/javascript"></script>

The above link to MSDN doesn't lead to anything helpful regarding the Range attribute. What I and other non-english user wnat to know is "What to type and where to type it". Until that is resolved I' put 2010 express on the shelf. It give me the impression of not being an Internationally mature product yet.

Anyway, thanx for all the work with this guide.

wouldn't it make more sense if the javascript files in the _Layout.cshtml were placed at the end of the page prior to the

closing </body> tag instead of in the header?

I suppose that makes including extra scripts such as jquery

dependent plug-ins more/too complex than it ought to be...

Thanks.

The bottom of the _Layout.cshtml could read as:

<script src="@Url.Content("~/Scripts/jquery-1.6.2.min.js")" type="text/javascript"></script>

<script src="@Url.Content("~/Scripts/modernizr-2.0.6-development-only.js")" type="text/javascript"></script>

@RenderSection("extra_js", required: false)

</body>

</html>

Then in the /Movies/Edit.cshtml page:

@section extra_js {

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

}

The tutorial could likely include this without adding much complexity,

and it might be a nice intro to how layouts can work in Razor. Have to say, looks much better than the webforms master page mode of design.

I feel obliged to point out, however, that DRY, is not only a design tenet of MVC, but one of the fundamental paradigms in OOP/OOD. It's very hard to overestimate the importance of this principle. Meta-programming really helps keeping things DRY, and has been around, (in the form of attributes) since .NET 1.1, so this is also not MVC - specific.

What really interests me most, as a freshman to web, is how to keep the views DRY? They clearly contain repetitive code

I noticed after I modified my Movie.cs, run app, and browse the movies controller;

the 'Rio Bravo II' record is missing...

What about if I regenerate the model classes again then I will lost all the validation

So there no idea to separate the model awy from the validation or some thing likes that ?

thanks

It's easy.
