collective.handlebars 1.0rc1

Features

The prodcut provides the following view components with handlebars support:

• BrowserView

• Plone template

• Tile

Since portlets and viewlets do not make any assumtion on the templating and return everything which is returned by the render-method of the Renderer they are supported too.

Examples

A handlebar BrowserView:

from collective.handlebars.browser.views import HandlebarsBrowserView

class HBSBrowserView(HandlebarsBrowserView):

    def get_contents(self):
        return {'msg': u'Hello World!'}

And the according configure.zcml:

<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:browser="http://namespaces.zope.org/browser"
    i18n_domain="mydomain">

  <browser:page
       name="carousel_view"
       for="*"
       class=".views.HBSBrowserView"
       template="helloworld.hbs"
       permission="zope2.View"
       />

A handlebar Plone template:

from collective.handlebars.browser.views import HandlebarsPloneView

class CarouselView(HandlebarsPloneView):

    def get_contents(self):
        images = self.context.listFolderContents(
            contentFilter={'portal_type': ['Image', ]})

         slides = [{'title': safe_unicode(img.Title()),
                    'category': safe_unicode(img.Description()),
                    'link': img.remoteUrl,
                    'image': scale(img)} for img in images]

         return {'slides': slides, }}

And the according configure.zcml:

<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:browser="http://namespaces.zope.org/browser"
    i18n_domain="mydomain">

  <browser:page
       name="carousel_view"
       for="*"
       class=".views.CarouselView"
       template="carousel.hbs"
       permission="zope2.View"
       />

</configure>

A handlebar portlet:

from collective.handlebars.browser.views import HandlebarsMixin
from plone.app.multilingual.browser.selector import LanguageSelectorViewlet

class LanguageSwitcherRenderer(base.Renderer, HandlebarsMixin):
    """ Render a language switcher portlet
    """

    def get_contents(self):
        """ Get available and current site language
        :return: dictonary ()
        """
        viewlet = LanguageSelectorViewlet(self.context, self.request, self, None)
        viewlet.update()
        result = []
        for lang in viewlet.languages():
            result.append(
                {"lang": lang['code'].upper(),
                 "url": lang['url'],
                 "active": lang['selected'] and 'is_active' or ''})

        return {"languages": result}

    def render(self):
        return self.hbs_snippet(filename='langswitcher.hbs')

A handlebar tile:

class ContactPersonTile(HandlebarTile):

    def get_contents(self):
        """ Get CMS data and put it in a JSON format
        """

        return {
            'fullname': u'George Miller',
            'phone': '+1 50 206 67 99',
            'email': 'george@example.com',

    xmlns:plone="http://namespaces.plone.org/plone"
