class litestar.template.TemplateConfig

基类：Generic[EngineType]

Configuration for Templating.

To enable templating, pass an instance of this class to the Litestar constructor using the 'template_config' key.

engine: type[EngineType] | EngineType | None = None

A template engine adhering to the TemplateEngineProtocol.

directory: PathType | list[PathType] | None = None

A directory or list of directories from which to serve templates.

engine_callback: Callable[[EngineType], None] | None = None

A callback function that allows modifying the instantiated templating protocol.

__init__(engine: type[EngineType] | EngineType | None = None, directory: PathType | list[PathType] | None = None, engine_callback: Callable[[EngineType], None] | None = None, instance: EngineType | None = None) → None

instance: EngineType | None = None

An instance of the templating protocol.

__post_init__() → None

Ensure that directory is set if engine is a class.

to_engine() → EngineType

Instantiate the template engine.

property engine_instance: EngineType

Return the template engine instance.

class litestar.template.TemplateEngineProtocol

基类：Protocol[TemplateType_co, ContextType_co]

Protocol for template engines.

__init__(directory: Path | list[Path] | None, engine_instance: Any | None) → None

Initialize the template engine with a directory.

参数:

• directory -- Direct path or list of directory paths from which to serve templates, if provided the implementation has to create the engine instance.

• engine_instance -- A template engine object, if provided the implementation has to use it.

get_template(template_name: str) → TemplateType_co

Retrieve a template by matching its name (dotted path) with files in the directory or directories provided.

参数:

template_name -- A dotted path

返回:

Template instance

抛出:

TemplateNotFoundException -- if no template is found.

render_string(template_string: str, context: Mapping[str, Any]) → str

Render a template from a string with the given context.

参数:

• template_string -- The template string to render.

• context -- A dictionary of variables to pass to the template.

返回:

The rendered template as a string.

register_template_callable(key: str, template_callable: Callable[[Concatenate[ContextType_co, P]], R]) → None

Register a callable on the template engine.

参数:

• key -- The callable key, i.e. the value to use inside the template to call the callable.

• template_callable -- A callable to register.

返回:

None

class litestar.template.TemplateProtocol

Template is a class that has a render method which renders the template into a string.

render(*args: Any, **kwargs: Any) → str

Return the rendered template as a string.

参数:

• *args -- Positional arguments passed to the TemplateEngine

• **kwargs -- A string keyed mapping of values passed to the TemplateEngine

返回:

The rendered template string
