Orchard CMS work with MediaPickerField defined in Migrations.cs

Question

MediaPickerFields still elude me.

I've defined a new Part in Migrations.cs and added a Boolean column and a MediaPickerField to the part as follows:

SchemaBuilder.CreateTable("ImageContentPartRecord", table =>
            table.ContentPartRecord()
            .Column("DisplayImage", DbType.Boolean));

ContentDefinitionManager.AlterPartDefinition("ImageContentPart", builder =>
            builder
                .Attachable()
                .WithField("ImageField", fld =>
                    fld.OfType("MediaPickerField")
                    .WithDisplayName("Image")));

Assuming I have ImageContentPart and ImageContentPartRecord classes, how can I retrieve the data from my MediaPickerField (url, dimensions, alt text, class, etc) in my Driver and in my Part Templates (Edit / Display)?

i.e. - Parts.ImageContent.cshtml (I want to accomplish something like this):

<div>
     <img src="@Model.ImageField.Url" alt="@Model.ImageField.Alt" />
</div>

Any ideas?

Here is the solution:

In my Display Driver method, I make sure to pass my ImageContentPart(part) when building the ContentShape:

return ContentShape("Parts_ImageContent", () =>
            shapeHelper.Parts_ImageContent(
                Content: part));

Then in my Template View, I leverage the dynamic nature of Orchard's architecture to consume my MediaPickerField. To do this, you access the .ContentItem property on your part, then leaning on dynamics, chain the part name (.ImageContentPart) and then the field name (.ImageContent) to access the field.

@{
    // Attempting to access MediaPickerField named 'ImageContent'
    var image = Model.Content.ContentItem.ImageContentPart.ImageContent;

    // Leaning on Orchard dynamics to access properties of the field
    var url = image.Url;
}

<img src="@url" alt="@T(image.AlternateText)" />

Here is an exhaustive list of MediaPickerField properties from \\Orchard.Fields\Views\Fields\MediaPicker.cshtml:

@* 
    Alternate Text: @Model.ContentField.AlternateText
    Class: @Model.ContentField.Class
    Style: @Model.ContentField.Style
    Alignment: @Model.ContentField.Alignment
    Width: @Model.ContentField.Width
    Height: @Model.ContentField.Height
    Url: @Model.ContentField.Url


    You can also display an image using this example, and add the attributes you need:
    <img src="@Href(Model.ContentField.Url)" />
*@
