piranha-cms - 获取/设置块上的列表字段

Question

这在我的 Models.Regions 课程中

public class Slider
{
    [Field]
    public StringField  Title       { get; set; }
    [Field]
    public TextField    Description { get; set; }
    [Field]
    public ImageField   Background  { get; set; }
    [Field(Title = "Text on Button")]
    public StringField  NameButton  { get; set; }
    [Field]
    public StringField  Link        { get; set; }
}

在 Models.Blocks 我制作了一个名为 SliderBlock.cs 的块，我需要插入一个滑块列表

[BlockType(Name = "Slider", Category = "Content")]
public class SliderBlock : Block
{
    public List<Models.Regions.Slider> Sliders { get; set; }
}

如何查看管理器的列表？

Answer 1

Blocks 的方法略有不同，不幸的是，该领域的文档不是最新的。要创建块列表，请使用 BlockGroup，对于接受单一类型元素的滑块，代码可以是：

[BlockGroupType(Name = "Slider", Category = "Content")]
[BlockItemType(Type = typeof(SliderItemBlock))]
public class SliderGroup : BlockGroup
{
}


[BlockType(Name = "Slider Item", Category = "Content", IsUnlisted = true)]
public class SliderItemBlock : Block
{
    [Field]
    public StringField Title { get; set; }

    [Field]
    public TextField Description { get; set; }

    [Field]
    public ImageField Background { get; set; }

    [Field(Title = "Text on Button")]
    public StringField NameButton { get; set; }

    [Field]
    public StringField Link { get; set; }
}

关于示例代码的几点说明。

1. As you can see them SliderGroup is in fact a Block as well. This means you can add fields to the Block Group as well if you want global fields that are valid for all of the items, for example background color. If you want to do this you need to add UseCustomView = true to the BlockGroupType attribute, and provide an EditorTemplate for the Block Group when you handle your global fields.
2. In the BlockType attribute I have added IsUnlisted = true. This means that SliderItemBlock will only be visible when adding an item to a SliderGroup, and not when adding a block to the general page flow.
3. You can specify multiple BlockItemType attributes for a group, this will give you the possibility to have a slider that supports different types of items. If you don't add any BlockItemType attributes to the group all block types will be available to add inside of the group.
4. Don't forget that block groups needs to be registered, just like normal blocks.

We've updated the documentation to include a section on how to create custom block groups which you can read here:
