Dapper Extensions dbConnection.Get<Object> - entity-framework

Question

Problem with: Dapper Extensions dbConnection.Get(personId)
I have a model called Person:
Person
{
public int PersonId { get; set; }
public string Name { get; set; }
}
In the database I have this table:
data.Persons
Pers_Id
Pers_Name
When I try this without any kind of custom mapping, I get an error "Invalid object name 'Person'."
I believe this is a mapping issue, because when I completely map the model with the prefix 'Pers_', and use 'data.Persons'
Get works.
But is there a way to automatically map with a prefix? The database I'm using has many different tables
with different prefices.
I also have everything already mapped to Entity framework. Is there a possibility of getting the map settings from
Entity DbModelBuilder?

Dapper-Extensions is convention based. For schema, it uses .dbo and for primary key it uses Id. If your tables don't match the convention, you will have to create a custom mapping.
public class MyModelMapper : ClassMapper<MyModel>
{
public MyModelMapper()
{
//use different table name
Table("table_name");
//use a custom schema
Schema("not_dbo_schema");
//have a custom primary key
Map(x => x.ThePrimaryKey).Key(KeyType.Assigned);
//Use a different name property from database column
Map(x=> x.Foo).Column("Bar");
//Ignore this property entirely
Map(x=> x.SecretDataMan).Ignore();
//optional, map all other columns
AutoMap();
}
}
An alternative is to use Dapper and just write your inline queries:
connection.Query("select * from foo.table where myId = {myId}", new {myId})
Update:
Another alternative is to play around with Code Generation and T4 Text Templates
Here is a trivial example
