A custom template loader which allows loading of templates from installed plugins.
|
|
|
|
Each plugin can register templates simply by providing a 'templates' directory in its root path.
|
|
|
|
The convention is that each 'templates' directory contains a subdirectory with the same name as the plugin,
|
|
e.g. templates/myplugin/my_template.html
|
|
|
|
In this case, the template can then be loaded (from any plugin!) by loading "myplugin/my_template.html".
|
|
|
|
The separate plugin-named directories help keep the templates separated and uniquely identifiable.
