Cannot insert duplicate key in objec 12 Years Ago by sufyan2011 I didn't read your code and also it is not possible but the error is simple you are trying to insert record in table and also passing the primary key value to table that is already exist in table. You can avoid such errors just to make the primary key autoincrement or put logic to check either your primary key value exist in DB then change it to … Re: Cannot insert explicit value for identity column in table 'client' when IDENTITY_INSE 12 Years Ago by hericles I'm not sure why you listed all that code. The part relevant to your SQL operation would have been adequate. I gave up looking for it so I don't know for certain the answer to your question but I would assume you are trying to insert a value into a column that is marked as IDENTITY. Option one (as the error message says) is to adjust your … Re: Entity framework validation error with controller 8 Years Ago by djjeavons Hi > Now, before you say "well then insert the key", please note that I have never had to do that before This is probably because your previous models used a public property with the name ID or *classNameID* such as EmployerDetailsID. Entity Framework will discern the primary key from this convention. However, in the model that you … Re: Entity framework validation error with controller 8 Years Ago by Violet_82 Ah that's it, absolutely right djjeavons, I did have an ID in other projects, but I had absolutely no idea that EF got its primary key from there! Thanks for clarifying that, I will include it. Also, just to clarify something else, isn't it better if the class fields are declared private? Re: Entity framework validation error with controller 8 Years Ago by djjeavons > Also, just to clarify something else, isn't it better if the class fields are declared private? Not necessarily. It depends on their use. Looking at your EmployerDetails class, it makes no sense to have them all declared as private as nothing will be able to access them. I wonder if you are confusing "fields" with properties? For … Re: Entity framework validation error with controller 8 Years Ago by Violet_82 maybe I'm getting confused, you're right, sorry it's that I'm still finding my way around MVC. In any case, thanks for clarifying things, much better now :-)!
