Reuse GridifyMapper

[Brandejs]

Hello,

First thanks for this project, it is really useful.

I am curious if it is possible to use an existing GridifyMapper and apply it to a "complex object". For example, I have an object Address. And I want to allow filtering only over some properties. The object is used in multiple entities, so I would like to restrict the given property on all entities. Similar to AutoMapper, where a DTO can be embedded and the correct map is used for it.

public class Address
{
    public string City { get; set; }
    public string Country { get; set; }
    public string Secret { get; set; }
}

public class User
{
    public string Email { get; set; }
    public Address Address { get; set; }
    // .... 
}

public class Company
{
    public string Name { get; set; }
    public Address Address { get; set; }
    // .... 
}


public class AddressGridifyMapper : GridifyMapper<Address>
{
    public AddressGridifyMapper()
    {
        AddMap("City", q => q.City);
        AddMap("Country", q => q.Country);
        
        // This field should not be allowed to filter
        // RemoveMap(nameof(Address.Secret))
    }
}

public class UserGridifyMapper : GridifyMapper<User>
{
    public UserGridifyMapper()
    {
        AddMap("Email", q => q.Email);
        
        // Reuse Mapper from AddressGridifyMapper
        AddMap("Address",  q => q.Address);
    }
}

public class CompanyGridifyMapper : GridifyMapper<Company>
{
    public CompanyGridifyMapper()
    {
        AddMap("CompanyName",  q => q.Name);
        
        // Reuse Mapper from AddressGridifyMapper
        AddMap("Address",  q => q.Address);
    }
}

That's a great suggestion! It's definitely worth exploring further, so I'll go ahead and turn this discussion into an issue.
