types ¤

Classes:

  • EmptyDict –

    TypedDict with no members.

Attributes:

EmptyTuple module-attribute ¤

EmptyTuple = Tuple[]

Tuple with no members.

You can use this to define a Component that accepts NO positional arguments:

from django_components import Component, EmptyTuple

class Table(Component(EmptyTuple, Any, Any, Any, Any, Any))
    ...

After that, when you call Component.render() or Component.render_to_response(), the args parameter will raise type error if args is anything else than an empty tuple.

Table.render(
    args: (),
)

Omitting args is also fine:

Table.render()

Other values are not allowed. This will raise an error with MyPy:

Table.render(
    args: ("one", 2, "three"),
)

EmptyDict ¤

Bases: TypedDict

TypedDict with no members.

You can use this to define a Component that accepts NO kwargs, or NO slots, or returns NO data from Component.get_context_data() / Component.get_js_data() / Component.get_css_data():

Accepts NO kwargs:

from django_components import Component, EmptyDict

class Table(Component(Any, EmptyDict, Any, Any, Any, Any))
    ...

Accepts NO slots:

from django_components import Component, EmptyDict

class Table(Component(Any, Any, EmptyDict, Any, Any, Any))
    ...

Returns NO data from get_context_data():

from django_components import Component, EmptyDict

class Table(Component(Any, Any, Any, EmptyDict, Any, Any))
    ...

Going back to the example with NO kwargs, when you then call Component.render() or Component.render_to_response(), the kwargs parameter will raise type error if kwargs is anything else than an empty dict.

Table.render(
    kwargs: {},
)

Omitting kwargs is also fine:

Table.render()

Other values are not allowed. This will raise an error with MyPy:

Table.render(
    kwargs: {
        "one": 2,
        "three": 4,
    },
)
