I would like to separate my attribute decoration(3-4 per field) by having them someplace else so that my code looks readable.Also the arguments passed to some attributes should come from a resource file.EG:[Required("Cannot proceed without entering *field_Name*")]
I need just [Required] Possible duplicate of this question(on which i couldn't resist offering a bounty) : Default resource for data annotations.
i use vs 2010 ultimate. i created a 'asp.net web application' from scratch, right clicked app_data and added a new sql server database (named MyDB), built two tables and saved it, added a 'ado.net entity model' to my project(named EDM_MyDB). then i dragged and dropped a 'list view' and 'entity data source' on my default.aspx. i tried to configure my 'entity data source' instance. in configuration window, underconnection string i tried to choose my entity instance (which i'd created before) but suddenly a popup message came up and said: The metadata specified in the connection string couldn't be loaded. Consider rebuilding the web project to build assemblies that may contain data. The following error(s) occurred: Unable to load the specified metadata resource.here is my whole connection string tab:
[Code]....
I have just deployed my ASP.NET MVC 2 application using EF 4 and I am getting the following error:
Unable to load the specified metadata resource.
On my local machine it runs fine with no errors. This error only comes now when I deployed to the server. I have my enity data model file in MyProject.EntityModel. I used the POCO entity generator to separate my context and entities. These 2 are in another project called MyProject.Entities. I have the connection strings in the app.config in the 2 projects exactly the same. The connection string in the web.config in my MVC app is also the same. I'm not sure why this is giving me issues? I'm also running the app in IIS (that comes with Windows 7) and it works fine. The IIS version on the server is 6 (I think). Here is the full error message:
InnerException

My case:I am developing an application that will run for multiple clients, each client has the ability to customize field displays and error messages.My issue:I created some custom attributes which inherit from DisplayNameAttribute, RequiredAttribute etc... and in them I am pulling out the resource needed.However it is only executed the once, so if my context changes it will be pulling the incorrectly cached value instead of pulling the new value need.Has anybody attempted to try something like this with the data annotations? Or any advice such as just don't use them for this scenario?
View 2 RepliesIn my project I use Strong Types Views. Because I find it nice structured.
public abstract class AbstractViewData: View Page ( ICollection Foo; )
public class HTML Component View Data: AbstractViewData ( string Foo2; )
I have the same structure in my code, as in the corresponding pages.And here starts the problems. I would like to use HTML.Display (o => o.Foo) could be a customer for that matter.But my Strong Types Views have not posted Metadata Model into my classes.Like: Return View ( "FooView", customer); would.Is there a way to write some code that can solve this problem for me?
I'm working on an ASP.NET MVC 2 project with some business entities that have metadata dataannotations attributes applied to them (Validation attributes, Display attributes, etc.).
Something like:
[Code]....
Using the metadata from different views is no problem, as long as I am using my business entities as viewmodels or as part of a viewmodel like this:
[Code]....
However, sometimes I need to code a view for editing some, but not all fields of an entity. For those fields I want to reuse the metadata already specified in my user entity. The other fields should be ignored. I'm talking about custom view models like this:
[Code]....
That's where I am running into problems. The custom view model above leads to an exception when the view is generated, because it has no password property.
The associated metadata type for type 'Zeiterfassung.Models.ViewModels.Users.UserNameViewModel+UserModel' contains the following unknown properties or fields: Password. make sure that the names of these members match the names of the properties on the main type.
Also, even if this exception did not occur, I expect to get into even more trouble with model validation on form submit because Password is marked as required in my business entity.
I can think of several workarounds, but none seem really ideal. In any case I can't change the database layout so that the password field would be in a separate entity in my example above.
How would you handle this scenario?
i am working an asp.net mvc 2 web app using model metadata and some of the model metadata don't seem to work when using the default Html.EditorForModel().For example, when applying the DefaultValue(1) and the ReadOnly(true) attributes on a model field, the field displayed on edit view has zero for its default value and it is not read only.
View 5 RepliesI was wondering if anyone can point me in the right direction? I have a POCO model and I am using Code First CTP. In my application, I set the database to be recreated whenever the model changes.
I would like to write custom functionality to access the model (POCO) metadata same way as EF sees it and use that to generate some source files (using T4). I would like to access the processed model not having to worry about finding properties that hold primary keys or any other conventions (implicit or not). What is the way to go about it?
I have a class library and was to add a resource file to it to support both English and Spanish. Any tips as how I can do this? The language will be dictated by the user visiting the site. Would like to have to only load each resource file once and cache or set in static variable and avoid any overheads.

View 1 RepliesIn our web application we need to keep various company's settings. For eg "DiamondProdRefIDCaption","Shippingpickup","ZipCodeCaption","DefaultCountry","AllowToEditInvoice", etcThese settings are different for various companies and are placed in web.config as key-value pair.Initially, we have tried do simplify this process by adding a company_settings table in the DB so as to allow us to add companies on the fly. However, this method makes it very difficult to add a new setting

I have a problem with passing a model to a controllerIn my controller I have a HttpPost function that gets a EF model.The problem is that the form does not contains all properties of the EF model.When the function is called that gets this EF model, I get error messge of fields that are not nullable in the EF model.That's because the fields are not in the form, so the not nullable properties gets no value.
View 5 RepliesI have a web project with a data model defined in an edmx file. The connection string starts like this:
metadata=res://*/;
This has worked fine for a while. But somebody else working on the project created a dll that also uses the entity framework and added it to the bin folder. Now when I try to create my connection there is an error loading the metadata.
Aside from totally changing the way one or both of us is doing things, I wonder if the problem can be fixed if my connection string can be changed to only look for the metadata defined in my edmx file. The problem is, for the life of me I can't find the right syntax to do this. The metadata is embedded in the output assembly, so there are no physical metadata files to point to. How exactly should I specify the metadata location in the connection string?

View 1 RepliesI would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?
[code]....
One of the fields on the view does not have a label when i ran the project, although the other fields got labels and the following HTML code to generate the label already exists:-
<%: Html.LabelFor(model => model.Article_Type_ID) %>
By picking MVC for developing our new site, I find myself in the midst of "best practices" being developed around me in apparent real time. Two weeks ago, NerdDinner was my guide but with the development of MVC 2, even it seems outdated. It's an thrilling experience and I feel privileged to be in close contact with intelligent programmers daily. Right now I've stumbled upon an issue I can't seem to get a straight answer on - from all the blogs anyway - and I'd like to get some insight from the community. It's about Editing (read: Edit action). The bulk of material out there, tutorials and blogs, deal with creating and view the model.
So while this question may not spell out a question, I hope to get some discussion going, contributing to my decision about the path of development I'm to take. My model represents a user with several fields like name, address and email. All the names, in fact, on field each for first name, last name and middle name. The Details view displays all these fields but you can change only one set of fields at a time, for instance, your names. The user expands a form while the other fields are still visible above and below. So the form that is posted back contains a subset of the fields representing the model. While this is appealing to us and our layout concerns, for various reasons, it is to be shunned by serious MVC-developers.
I've been reading about some patterns and best practices and it seems that this is not in key with the paradigm of viewmodel == view. Or have I got it wrong? Anyway, NerdDinner dictates using FormCollection och UpdateModel. All the null fields are happily ignored. Since then, the MVC-community has abandoned this approach to such a degree that a bug in MVC 2 was not discovered. UpdateModel does not work without a complete model in your formcollection. The view model pattern receiving most praise seems to be Dedicated view model that contains a custom view model entity and is the only one that my design issue could be made compatible with.
It entails a tedious amount of mapping, albeit lightened by the use of AutoMapper and the ideas of Jimmy Bogard, that may or may not be worthwhile. He also proposes a 1:1 relationship between view and view model. In keeping with these design paradigms, I am to create a view and associated view for each of my expanding sets of fields. The view models would each be nearly identical, differing only in the fields which are read-only, the views also containing much repeated markup. This seems absurd to me. In future I may want to be able to display two, more or all sets of fields open simultaneously.
So i'm working on the form that i started MVC with - the problem is that i'm NOT using a ViewModel for the view, its an actual Linq to SQL object. And so far it works fine. This form is a beast and id rather not refactor it to use viewmodels....
My big problem now is that depending some condition, i pretty much set almost everything to disabled when a particular dropdown is selcted (to mimic a deactivated state) - when the user hits submit, the model fields are now null, even tho you can see them filled in (just greyed out and unselectable) and validation refuses them.
Is there anyway around this other than to refactor the Views to use ViewModels (and set different validation rules so submit works)?
How can i make this work like i have 5 fields in my database table . 2) i created a model for validation with datannotation and created the compare password field as well with comparepassword attribute. (now my model has 6 fields including one external field compare password and 5 database fields)3) i created a view with that model.(User)4) now i created a controller as well but the problem arise here that when calling that actionmethod the compiler complains about the external field and tells it cannot find any extension method . how can i create the extension method or solve this error?

I am beginner to MVC. I have created a View with dropdownlist, text box and text area. I didn't create a strongly typed view because these fields are not generating from the database. Is this right way of doing it? Do I have to create a 'Model' class and generate a strongly typed view? I am trying to validate(client and server side) these fieds before saving into the database. How to create a Model class for these fields?
Here is my view looks like.

i just noticed that if my controller has a parameter with a name that matches the name of a field in my view model, and the view emits the value of the model's field, the value emitted is that passed in the query string, not the one set by the controller. is this by design?
here is what i mean:
my view model:
public class MyViewModel
{
int id;
string name; [code]....
sending a request to "create?id=1234" emits "1234" in the hidden field instead of "1".
I am facing few issues. I am using MVC2.I am developing a form which is being created dynamically based on its layout and all html attributes info stored in DB table. This dynamically generated form stores data(this table have all html field names as columns) in another db table(db is mysql).
I have created ViewModel class in which i get both design table entity objects and data table entity object. I, then, created strongly typed view based on that ViewModel. But the problem is when i rendering html fields using html helpers i.e
TextBox(Model.tblDesign.htmlField_name).it doesnt bind with the columns of Model.tblData whose names are same as of Model.tblDesign.htmlField_name. how can i bind fields of data table?
