tmsmith / Dapper-Extensions

Dapper Extensions is a small library that complements Dapper by adding basic CRUD operations (Get, Insert, Update, Delete) for your POCOs. For more advanced querying scenarios, Dapper Extensions provides a predicate system. The goal of this library is to keep your POCOs pure by not requiring any attributes or base class inheritance.

Unable to mapped underscore column in dapper extension #307

Hi, I have a user data model containing some underscore columns but I'm unable to insert, update and get records using the dapper extension library it is throwing a reflection error below you can see:

at DapperExtensions.ReflectionHelper.GetParameter(Type entityType, ISqlGenerator sqlGenerator, String propertyName, Object value) at DapperExtensions.DapperImplementor.AddParameter[T](T entity, DynamicParameters parameters, IMemberMap prop, Boolean useColumnAlias) at DapperExtensions.DapperImplementor.GetDynamicParameters[T](T entity, IClassMapper classMap, IList1 sequenceColumn, IList1 foreignKeys, IList1 ignoredColumns, Boolean useColumnAlias) at DapperExtensions.DapperImplementor.GetDynamicParameters[T](IClassMapper classMap, T entity, Boolean useColumnAlias) at DapperExtensions.DapperImplementor.InternalUpdate[T](IDbConnection connection, T entity, IClassMapper classMap, IPredicate predicate, IDbTransaction transaction, IList1 cols, Nullable1 commandTimeout, Boolean ignoreAllKeyProperties) at DapperExtensions.DapperAsyncImplementor.<InternalUpdateAsync>d__151.MoveNext() at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at DapperExtensions.DapperAsyncImplementor.d__161.MoveNext() at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at DapperExtensions.DapperAsyncImplementor.<UpdateAsync>d__31.MoveNext() at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at DapperExtensions.AsyncDatabase.d__81.MoveNext() at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter1.GetResult()

User Data Model:

public class Permission { public Guid Id { get; set; } public string permission_code { get; set; } public string role_code { get; set; } public bool HasPermission { get; set; } public string PermissionStatus { get; set; } public string addl_data { get; set; } }

await db.Update(roleView, null, true);

Also, I set this property before and after the connection opened but this is not working throwing the above exception:

IDbConnection con = CreateConnection(); if (con == null) throw new ApplicationException("CreateConnection function did not return a valid connection"); DefaultTypeMap.MatchNamesWithUnderscores = true; con.Open();

I have same problem too with predicates(Ex : var a = Predicates.Field(x => x.status_cd, Operator.Eq, "1")) Here is error : 'cd was not found for sys_status'

Hi @hatuan, I fixed in repo and created a pull request for approval to @valfrid-ly, waiting for approve once approved so you will get the fixed in github project.
