Migrating Types with Named Parts

[skiaz]

Hello everybody,

I'm looking for suggestions for adding named parts to a content type.
Currently, I have some content types already defined (via Orchard UI), and they are already used, but now I want to move all part and types into the code. The parts and types should come as a feature/module, which can be enabled. Whenever I create a new tenant, I can just enable this feature and everything is there.
This approach works well so far.

Now, I got to a point where I don't know how to add a named part to a content type in the migrations class.
I have the following code:

_contentDefinitionManager.AlterTypeDefinition(nameof(FooterWidget), type => type
                .DisplayedAs("Footer")
                .Creatable()
                .Listable()
                .Draftable()
                .Securable()
                .WithSettings(new FullTextAspectSettings
                {
                    IncludeBodyAspect = true,
                    IncludeDisplayText = true
                })
                .WithPart(nameof(TitlePart), part => part
                    .WithSettings(new TitlePartSettings
                    {
                        RenderTitle = true,
                        Options = TitlePartOptions.Editable
                    })
                )
                .WithPart(nameof(FooterWidget))
                .WithPart(nameof(BagPart), part => part
                    .WithDisplayName("Columns")
                    .WithDescription("Adds a column to your footer.")
                    .WithSettings(new BagPartSettings(){ContainedContentTypes = new []{ "FooterColumn" }})
                )
            );

In this example code the last "BagPart" needs to get another technical name.

I'm open for some ideas from the community. Maybe someone had a similar issue and can help me here. I'm trying to avoid any configurations involving JSON files.

Thanks

Found the solution, I just had to give an additional string into the WithPart method.

.WithPart("ThisIsACustomTechnicalName", nameof(BagPart), part => part
                    .WithDisplayName("Columns")
                    .WithDescription("Adds a column to your footer.")
                    .WithSettings(new BagPartSettings(){ContainedContentTypes = new []{ "FooterColumn" }})
                )
