Python wagtail Structural Block

In the previous article we have discuss about Basic Blocks.If you have not gone through it you see through this link Basic Block.

In addition to the basic block types , it is possible to define new block types made up of sub-blocks: for example, a 'person' block consisting of sub-blocks for first name, surname and image, or a 'carousel' block consisting of an unlimited number of image blocks this new type of block are known as structural block.

  Following are the list of block structural list 

    StructBlock  ( wagtail.core.blocks.StructBlock)

A block consisting of a fixed group of sub-blocks to be displayed together. Takes a list of tuples as its first argument.

('person', blocks.StructBlock([
('first_name', blocks.CharBlock()),
('surname', blocks.CharBlock()),
('photo', ImageChooserBlock(required=False)),
('biography', blocks.RichTextBlock()),
], icon='user'))

   ListBlock  (wagtail.core.blocks.ListBlock)

A block consisting of many sub-blocks, all of the same type. The editor can add an unlimited number of sub-blocks, and re-order and delete them.

('ingredients_list', blocks.ListBlock(blocks.CharBlock(label="Ingredient")))

   StreamBlock (wagtail.core.blocks.StreamBlock)

A block consisting of a sequence of sub-blocks of different types, which can be mixed and reordered.

('carousel', blocks.StreamBlock(
('image', ImageChooserBlock()),
('quotation', blocks.StructBlock([
('text', blocks.TextBlock()),
('author', blocks.CharBlock()),
('video', EmbedBlock()),

As with StructBlock, the list of sub-blocks can also be provided as a subclass of StreamBlock.

class CarouselBlock(blocks.StreamBlock):
image = ImageChooserBlock()
quotation = blocks.StructBlock([
('text', blocks.TextBlock()),
('author', blocks.CharBlock()),
video = EmbedBlock()

class Meta:
 StreamBlock accepts the following options as either keyword arguments 
  • required
  • min_num
  • max_num
  • block_counts
