entity-framework-5

I am just learning MVC and dealing with its stateless nature in combination with Entity Framework. My question is, is there a more elegant way of handling the scenario below? I have two POCO entities: public class Contest { public long ID { get; set; } .... ..... public ICollection<ContestPrize> Prizes { get; set; } } public class ContestPrize { public long ID { get; set; } public Contest Contest { get; set; } } I then have a MVC View that displays the Contest and all the Prizes associated with them. On that view I have a "Create Prize" link to create a new prize which passes the ID of the

At work we just upgraded to Entity Framework 5. Our EDMX file now has a couple other nodes beneath it: EntityContainer.Context.tt which contains the generated DbContext object and EntityContainer.tt which contains the entities themselves. For a short period, adding an entity in EF was automatically regenerating the tt (T4 Templates) when we would save the EDMX file. Now all of a sudden we have to right-click the T4 templates and select "Run Custom Tool" to get them to regenerate the .cs files for the context or entities. Any ideas how this might have happened? Update In the EDMX the property

So I am starting this new project and want to use Log4net to log to the Database. I am using EF for other things and it connects fine. For some reason L4N is not logging anything but not throwing any errors. Just wondering what step(s) I may be missing, hope someone can point it out. Do I need to "save" to the db somehow? Thanx so much in advance. My web.config: <log4net> <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender"> <bufferSize value="100" /> <connectionType value="System.Data.EntityClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral,

I have writting a LINQ query to fill a listview but it useses the .ToString() method which apparetly is not allowed. When I use the below code I get the error message: Error: LINQ to Entities does not recognize the method 'System.String ToString()' method, and this method cannot be translated into a store expression Is there a way to use the ToString() in LINQ or if that is not possible what is the solution to converting a DateTime to String in the query. Please knot that ReleaseDateName is a string and ReleaseDate is a DateTime using (var db = new ReleaseInfo()) { lvReleaseInfo.DataSource =

I have a class called Client mapped to a database table using Entity Framework code first. The table has a computed field that I need available in my Client class, but I understand that it won't be possible to write to this field. Is there a way of configuring Entity Framework to ignore the property when saving, but include the property when reading? I have tried using the Ignore method in my configuration class, or using the [NotMapped] attribute, but these prevent the property from being read from the database. You can use DatabaseGeneratedAttribute with DatabaseGeneratedOption.Computed

Suppose that I have a database with 1 table named Products . So, I go through the Db First approach and create an EF model in VS 2012 with pluralize and singularize option. So, the model creates a Product entity for me, and default naming convention maps this entity to the dbo.Products table. Now I want to change this behavior. In fact I want to create a custom convention to map ProductModel entity to the dbo.Products table. Is this possible?! If so, how? Update: My goal to do it... As you know, whenever you update your model from database, if it causes a change in your model, the auto

I currently have a view that contains two text boxes where users can enter in some data. One text box only allows values of 1-10, the other a string. I am not sure what code change I made, but the second text box accepting a string no longer "works". For example, when I enter in a string and try to submit the form, I get a validation message that states "The value "(string)" is invalid. Below are some code snippets in my solution. Entity: public class MovieReview { public int Id { get; set; } [Range(1, 10)] [Required] public int Rating { get; set; } public string Review { get; set; } public
