collective.configviews

Introduction

This add-on does not provide new feature to Plone. It is intended to plone add-ons developers.

If you need to create a browser view with configuration this add-on will make your life easier.

Features:

• Configuration providers
• Configuration structure defined with zope.interface & zope.schema
• Store configuration with plone.app.registry
• Auto form to manage the configuration of the current view

Why doing this in an add-on

Because most of the time developers faced to this issue store data in the content type, or with annotation on context without trying to optimize, or without form, ...

How it works

This add-ons define two components:

• ConfigurableView
• Registry (IConfigurationStorage)

The main idea, is you just have to create an zope.interface to define settings schema and set this schema in the 'settings_schema' attributes of the view.

For example:

class IMyViewSettings(interface.Interface):
    width = schema.ASCIILine(title=u"Width",
                             default='620')

    height = schema.ASCIILine(title=u"Height",
                              default='620')

class MyView(ConfigurableBaseView):
    settings_schema = IMyViewSettings

    def width(self):
        return self.settings.width

    def height(self):
        return self.settings.height

Common use case: use a javascript library for a view

Most of javascript libraries wait for a dict to load their configuration. You can achieve this in a very easy way. You just have to define a configuration schema and add the following snippet in your template to create a javascript variable with the configuration

<script type="text/javascript" tal:content="view/settings_javascripts"></script>

You can set the variable name throw the jsvarname attribute of your browserview.

You will find examples in the following addons:

• collective.galleria
• collective.galleriffic
• collective.googledocsviewer
