Extending an existing plugin

For extending an existing smart-plugin with a webinterface, the following steps have to be followed:

  1. Add the webif directory from the sample plugin to the plugin’s directory
  2. Change the import statement for lib.smartplugin from from lib.model.smartplugin import SmartPlugin to from lib.model.smartplugin import *
  3. Add the following statement to the __init__ method of the plugin: self.init_webinterface()
  4. Ad the method init_webinterface to the plugin’s class (copy from sample_plugin)
  5. Add the WebInterface class after the end of the plugin’s class definition. Copy it from the sample plugin.

Now the plugin has a functional but empty webinterface:


The Method index of the class WebInterface implements the page of the web interface. It renders the template and makes all data of the plugin public to the render engine (return tmpl.render(p=self.plugin)) as p. If further data is needed, it has to be added to tmpl.render().

Now the only thing left to do, is adding the data that shall be displayed to the template file (webif/templates/index.html).
