Components

id

The id of the element. This corresponds to the HTML id, hence it must be unique throughout the document. If not given, this will be set with a unique UUID4.

cid

The CBA internal component id of a component. If not set this defaults to the ´´id´´.

The cid is used to get the component out of the component tree.

component-value

The CBA internal value of a component. If not set this defaults to the cid of the components.

First call

1. Django -> cba.views.get() -> root() -> root.init_components() -> components.init_components()
2. Django -> cba.views.get() -> root.render() -> [components.render()]

There are two ways to add intial sub components to a component

1. With construction (__init__)

components.Group(
    initial_components=[
        components.HTML(content="Hello"),
        components.Button(value="OK!"),
    ]
)

2. Subclass, overwrite the init_components method and set self.initial_components within it.

class MyGroup(components.Group)
    def init_components(self):
        self.initial_components = [
            components.HTML(content="Hello"),
            components.Button(value="OK!"),
        ]
