cement.core.template

Cement core template module.

class cement.core.template.TemplateHandler(*args, **kwargs)

Bases: cement.core.template.TemplateInterface, cement.core.handler.Handler

Base class that all template implementations should sub-class from. Keyword arguments passed to this class will override meta-data options.

copy(src, dest, data, force=False, exclude=None, ignore=None)

Render src directory as template, including directory and file names, and copy to dest directory.

Parameters:

• src (str) – The source directory path.
• dest (str) – The destination directory path.
• data (dict) – The data dictionary to interpolate in the template.
• force (bool) – Whether to overwrite existing files.
• exclude (list) – List of regular expressions to match files that should only be copied, and not rendered as template.
• ignore (list) – List of regular expressions to match files that should be completely ignored and not copied at all.

Returns:

Returns True if the copy completed successfully.

Return type:

bool

Raises:

AssertionError – If the src template directory path does not exists, and when a dest file already exists and force is not True.

load(template_path)

Loads a template file first from self.app._meta.template_dirs and secondly from self.app._meta.template_module. The template_dirs have presedence.

Parameters:template_path (str) – The secondary path of the template after either template_module or template_dirs prefix (set via App.Meta) Returns:The content of the template (str), the type of template (str: directory, or module), and the path (str) of the directory or module) Return type:tuple Raises:cement.core.exc.FrameworkError – If the template does not exist in either the template_module or template_dirs.

render(content, data)

Render content as template using using the data dictionary.

Parameters:

• content (str) – The content to render.
• data (dict) – The data dictionary to interpolate in the template.

Returns:

The rendered content.

Return type:

str

class cement.core.template.TemplateInterface(**kw)

Bases: cement.core.interface.Interface

This class defines the Template Interface. Handlers that implement this interface must provide the methods and attributes defined below. In general, most implementations should sub-class from the provided TemplateHandler base class as a starting point.

class Meta

Bases: object

Handler meta-data.

interface = 'template'

The string identifier of the interface

copy(src, dest, data)

Render the src directory path, and copy to dest. This method must render directory and file names as template content, as well as the contents of files.

Parameters:

• src (str) – The source template directory path.
• dest (str) – The destination directory path.
• data (dict) – The data dictionary to render with template.

Returns: None

load(path)

Loads a template file first from self.app._meta.template_dirs and secondly from self.app._meta.template_module. The template_dirs have presedence.

Parameters:path (str) – The secondary path of the template after either template_module or template_dirs prefix (set via App.Meta) Returns:The content of the template (str), the type of template (str: directory, or module), and the path (str) of the directory or module) Return type:tuple Raises:cement.core.exc.FrameworkError – If the template does not exist in either the template_module or template_dirs.

render(content, data)

Render content as a template using the data dict.

Parameters:

• content (str) – The content to be rendered as a template.
• data (dict) – The data dictionary to render with template.

Returns:

The rendered template string.

Return type:

str
