I have an entity called Request. I created in the Model folder a class that loads the Orders, called GetPedidos . Well, when I created the controller, I added a view to the Action Index . When building the view, I had her use the GetPedidos model. When I squeeze, it gives me this error:
The template item entered in the dictionary is from type 'System.Collections.Generic.List'1 [TSL.Domain.Entities.Prev]', but this dictionary requires an item of type 'System.Collections.Generic.IEnumerable'1 [TSL.Models.GetData]'.
Exception Details: System.InvalidOperationException: The model inserted in the dictionary is type 'System.Collections.Generic.List'1 [TSL.Domain.Entities.Prev]', but this dictionary requires an item of type 'System.Collections.Generic.IEnumerable'1 [TSL.Models.GetData]'.
I understand the error, I just do not know how to change it, that is, whether or not to use the GetPedidos

The Error
The template item entered in the dictionary is from type 'System.Collections.Generic.List
1[TSL.Domain.Entities.Pedido]', mas esse dicionário requer um item do tipo 'System.Collections.Generic.List1 [TSL.Models.GetData]'.
The view is like this
@model List<TSL.Models.GetPedidos>
