Browser layer management for Zope 2 applications

Project description

Introduction

This package aims to make it easier to register visual components (e.g. views and viewlets) so that they only show up in a Plone site where they have been explicitly installed.

Basic usage

To use this feature, you should:

  • declare plone.browserlayer as a dependency, e.g. in setup.py:

    install_requires=[
          'plone.browserlayer',
      ],
  • ensure that its ZCML is loaded, e.g. with an include from your own package:

    <include package="plone.browserlayer" />
  • create a layer marker interface unique to your product:

    from zope.interface import Interface
    class IMyProductLayer(Interface):
        """A layer specific to my product
        """
  • register this with GenericSetup, in a browserlayer.xml file:

    <layers>
        <layer name="my.product"
               interface="my.product.interfaces.IMyProductLayer" />
    </layers>
  • register visual components in ZCML for this layer, e.g.:

    <browser:page
        name="my-view"
        for="*"
        layer=".interfaces.IMyProductLayer"
        permission="zope.Public"
        template="my-view.pt"
        />

Changelog

2.1.2 (2012-10-03)

  • Add support for calling many times remove in export (ie:even when no corresponding layer is registred, remove option should not throw exception). [toutpt]

2.1.1 (2011-11-24)

  • Added uninstall support to browserlayer.xml with the ‘remove’ option. [maurits]

  • GS export xml is now repeatable. Before two consecutive exports could yield differently ordered results. [do3cc]

2.1 - 2011-05-12

  • Update import of BeforeTraverseEvent to come from zope.traversing instead of zope.app.publication. [davisagli]

  • Add MANIFEST.in [WouterVH]

2.0.1 - 2010-09-21

  • Make sure the layers don’t get applied twice if the site is traversed more than once (such as in a vhosting URL). [davisagli]

2.0 - 2010-07-18

  • Update license to GPL version 2 only. [hannosch]

  • Package metadata cleanup, require Zope2 distribution. [hannosch]

1.0.1 - 2009-09-09

  • Be more robust against broken layer registrations. These can occur when packages with registered layers are removed. [wichert]

  • Clarified license and copyright. [hannosch]

  • Register ourselves for the more generic ISiteRoot from CMFCore and not IPloneSiteRoot. [hannosch]

  • Declare test dependencies in an extra. [hannosch]

  • Specify package dependencies. [hannosch]

1.0.0 - 2008-04-20

  • Unchanged from 1.0rc4

1.0rc4 - 2008-04-13

  • Register the GenericSetup import and export steps using zcml. This means you will no longer need to install this package manually. [wichert]

1.0rc3 - 2008-03-09

  • Include README.txt and HISTORY.txt in the package’s long description. [wichert]

  • Add metadata.xml to the GenericSetup profile. This fixes a deprecation warning for Plone 3.1 and later. [wichert]
