Settings configuration for Kotti

Project Description

Add a settings configuration to your Kotti site.

Find out more about Kotti

You have a full example e.g. in the addon kotti_google_analytics.


To activate the kotti_controlpanel add-on in your Kotti site, you need to add an entry to the kotti.configurators setting in your Paste Deploy config. If you don’t have a kotti.configurators option, add one. The line in your [app:main] (or [app:kotti], depending on how you setup Fanstatic) section could then look like this:

kotti.configurators = kotti_controlpanel.kotti_configure

The add-on adds a new configuration page to save settings for your module or across different modules. It adds a new submenupoint named “Settings” to the menupoint “Site Setup”. Every setting collection is presented in one tab. It is intended to use one tab for a module, but it is also possible to use multiple tabs if you have the need for a more extended structure.

You can choose between two modes to set up your settings. With the “dict mode” you have a very easy and straightforward option to set up the settings. If you need more advanced forms you can set up an own schema.

A setting tab is set up with with a dictionary. Here you define a name and a title for your tab, what are required. Optional arguments are success_message, either settings or schema, schema_factory and use_csrf_token.

Define your settings in a dictionary:

TestSettings = {
    'name': 'test_settings',
    'title': "Testsettings",
    'icon': 'myaddon:static/icon.png',
    'description': "Some description for my settings",
    'success_message': u"Successfully saved test settings.",
    'settings': [
        {'type': 'String',
         'name': 'testsetting_1',
         'title': 'Test 1',
         'description': 'a test setting',
         'default': '', },
        {'type': 'Integer',
         'name': 'testsetting_2',
         'title': 'Test 2',
         'description': 'again a test setting',
         'default': 23, }]}

Define your settings with a schema:

class StringSchemaNode(colander.SchemaNode):
    name = 'a_string'
    title = 'hello'
    default = 'hello world'

class RangedIntSchemaNode(colander.SchemaNode):
    name = 'range_int'
    validator = colander.Range(0, 10)
    default = 5
    title = 'Ranged Int'

class TestSchema(colander.MappingSchema):
    string = StringSchemaNode(colander.String())
    ranged_int = RangedIntSchemaNode(colander.Int())

TestSettings = {
    'name': 'test_settings',
    'title': "Testsettings",
    'description': "Some description for my settings",
    'success_message': u"Successfully saved test settings.",
    'schema_factory': TestSchema

To get your configuration registered within kotti_controlpanel add the settings in a populator in your add-on. Have a look to the Kotti documentation to get more informations for populators and to see an example.

Add your settings configuration within a populator, e.g. in a file named

def populate():
    from kotti_controlpanel.util import add_settings

and add this to your configuration:

def kotti_configure(settings):
    settings['kotti.populators'] += ' my_addon.populate.populate'

or directly to your ini file:

kotti.populators = my_addon.populate.populate

To get your setting back into your code you use the following:

from kotti_controlpanel.util import get_setting

first_test_setting = get_setting('test_setting_1')

You can also add useful links to the main Control panel view by:

from kotti.util import Link
from kotti_controlpanel import CONTROL_PANEL_LINKS

def kotti_configure(settings):
    CONTROL_PANEL_LINKS.append(Link('setup-users', title='User Management'))


Before and after the settings are saved events for handling the changes are fired. To subscribe to the events use something like:

from import subscriber
from import SettingsAfterSave

def do_something_when_settings_saved(event):
    # Check if the settings for this module was saved.
    if not event.module == __package__:

Default schemas

kotti_controlpanel provides some default schemas that you can use directly in your code and for example purposes. Currently there are two schemas implemented, one to choose in what slot the widget should be shown and another one to set the visibility of the widget. To use it in your addon place something like the following in your populator:

from kotti.views.slots import assign_slot
from kotti_controlpanel.config import SlotSchemaNode
from kotti_controlpanel.config import ShowInContextSchemaNode
from kotti_controlpanel.util import add_settings
from kotti_controlpanel.util import get_setting
from kotti_myaddon import _

class MyWidgetSchema(colander.MappingSchema):
    slot = SlotSchemaNode(colander.String())
    show_in_context = ShowInContextSchemaNode(colander.String())

MyAddonSettings = {
    'name': 'myaddon_settings',
    'title': _(u'My Addon Settings'),
    'description': _(u"Settings for my addon"),
    'success_message': _(u"Successfully saved my addon settings."),
    'schema_factory': MyAddonSchema,

def populate():
