使用Entity Framework将视图中的字段映射到我的模型并将其设置为只读

Question

I am using Entity Framework code-first (non auto generated) and I am trying to map some properties in my OnModelCreating event. Most properties are from a SQL Server table however there is a field I want to include in my model from a view, I have done this and set it as [DatabaseGenerated(DatabaseGeneratedOption.Computed)] .

However EF tries to update the view, how do I tell EF to not update my view and treat it as read only, the error I get is...

Cannot update the view or function 'VIEWNAME' because it contains aggregates, or a DISTINCT or GROUP BY clause, or PIVOT or UNPIVOT operator

I can see plenty of things to make your view update-able but no to just treat it as read only

UPDATE

After trying a few things I have added [DatabaseGenerated(DatabaseGeneratedOption.Identity)] to the property when defining it in my model and this seems to have done the trick, seems a bit strange though as setting it as Identity doesn't make much sense to me over setting it as computed but seems to be working.

Answer 1

did you try this on your properties?

public virtual string MyProperty { get; internal set; }

this way the entity consumer cannot change it.
