Setup

To activate the kotti_settings 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_settings.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",
'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_settings 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 populate.py:

def populate():
    from kotti_settings.util import add_settings
    add_settings(TestSettings)

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_settings.util import get_setting

first_test_setting = get_setting('test_setting_1')

Events

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

from pyramid.events import subscriber
from kotti_settings.events import SettingsAfterSave

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

Default schemas

kotti_settings 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_settings.config import SlotSchemaNode
from kotti_settings.config import ShowInContextSchemaNode
from kotti_settings.util import add_settings
from kotti_settings.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():
    add_settings(MyAddonSettings)

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