collective.grok 1.0a2

注册配置文件

若要向zcml注册配置文件，应将以下元素添加到 configure.zcml（或它包含的其他文件）。

<genericsetup:registerProfile
  name="default"
  title="Portal policy for plone.org"
  directory="profiles/default"
  description="Installs dependencies and stuff for our portal"
  provides="Products.GenericSetup.interfaces.EXTENSION"
  i18n:attributes="title; description"
  />

使用collective.grok，将进行相同的注册（详细）：

from collective.grok import gs
from Products.GenericSetup.interfaces import EXTENSION
gs.profile(name=u'default',
           title=u'Portal policy for plone.org',
           description=u'Installs dependencies and stuff for our portal',
           directory='profiles/default',
           provides=EXTENSION)

要注册第二个配置文件（在我们的例子中，一个用于卸载），我们将 执行同样的操作（现在，不传递参数名）：

gs.profile(u'uninstall',
           u'Uninstall portal policy for plone.org',
           u'Removes dependencies and stuff from our portal',
           'profiles/uninstall',
           EXTENSION)

使用zope.i18nMessageFactory支持i18n。在 在配置文件注册之后，我们翻译配置文件标题和 其描述：

from my.package import MessageFactory as _
gs.profile(u'init',
           _(u'Initial content structure for plone.org'),
           _(u'Constructs folder structure and navigation'),
           'profiles/init',
           EXTENSION)

由于版本1.0a2，提供的参数的默认值是extension， 所以可以省略：

from collective.grok import gs

gs.profile(name=u'default',
           title=u'Portal policy for plone.org',
           description=u'Installs dependencies and stuff for our portal',
           directory='profiles/default')

注册导出步骤

使用zcml注册通用设置的导出步骤 包含以下元素元素以配置.zcml（或它包含的其他文件）。

<genericsetup:exportStep
    name="archetypetool"
    title="Archetype Tool"
    description="Export Archetype Tool."
    handler="Products.Archetypes.exportimport.archetypetool.exportArchetypeTool">
</genericsetup:exportStep>

注册指向一个处理程序，它实现实际的导出 代码：

def exportArchetypeTool(context):
    """Export Archetype Tool configuration.
    """
    site = context.getSite()
    logger = context.getLogger("archetypetool")
    tool = getToolByName(site, TOOL_NAME, None)
    if tool is None:
      return

    exportObjects(tool, '', context)
    logger.info("Archetype tool exported.")

摸索着，同样的登记也会在 带有导入和修饰程序的Archetypetool模块：

from collective.grok import gs

@gs.exportstep(name=u'archetypetool', title='Archetype Tool',
               description='Export Archetype Tool.')
def exportArchetypeTool(context):
    """Export Archetype Tool configuration.
    """
    site = context.getSite()
    logger = context.getLogger("archetypetool")
    tool = getToolByName(site, TOOL_NAME, None)
    if tool is None:
      return

    exportObjects(tool, '', context)
    logger.info("Archetype tool exported.")

同样，如果需要，您甚至可以省略参数名…

from collective.grok import gs

@gs.exportstep(u'archetypetool','Archetype Tool',
               'Export Archetype Tool.')
def exportArchetypeTool(context):
    """Export Archetype Tool configuration.
    """
    site = context.getSite()
    logger = context.getLogger("archetypetool")
    tool = getToolByName(site, TOOL_NAME, None)
    if tool is None:
      return

    exportObjects(tool, '', context)
    logger.info("Archetype tool exported.")

注册导入步骤

导入步骤与导出步骤的增量类似。所以，ZCML注册 完成（zcml文件）：

<genericsetup:importStep
    name="archetypes-various"
    title="Archetypes setup"
    description="Import various settings for Archetypes."
    handler="Products.Archetypes.setuphandlers.setupArchetypes">
   <depends name="componentregistry"/>
</genericsetup:importStep>

以及相应的python代码：

def setupArchetypes(context):
    """
    Setup Archetypes step.
    """
    # Only run step if a flag file is present (e.g. not an extension profile)
    if context.readDataFile('archetypes-various.txt') is None:
        return
    out = []
    site = context.getSite()
    install_uidcatalog(out, site)
    install_referenceCatalog(out, site)
    install_templates(out, site)

摸索一下，我们会：

from collective.grok import gs

@gs.importstep(name=u'archetypetool', title='Archetype Tool',
               description='Export Archetype Tool.',
               dependecies=['componentregistry',])
def setupArchetypes(context):
    """
    Setup Archetypes step.
    """
    # Only run step if a flag file is present (e.g. not an extension profile)
    if context.readDataFile('archetypes-various.txt') is None:
        return
    out = []
    site = context.getSite()
    install_uidcatalog(out, site)
    install_referenceCatalog(out, site)
    install_templates(out, site)

注册升级步骤

要使用zcml注册升级步骤，应将以下slug添加到 configure.zcml:

<genericsetup:upgradeStep
    title="Update portal title"
    description="Upgrade step used to update portal title"
    source="1000"
    destination="2000"
    sortkey="1"
    handler=".to2000.from1000"
    profile="my.package:default" />

处理程序代码如下所示：

def to2000(context):
    """
    Update portal title
    """
    site = context.getSite()
    site.title = u'A New Title'

collective.grok提供一个decorator来grok此代码：

from collective.grok import gs

@gs.upgradestep(title=u'Update portal title',
                description=u'Upgrade step used to update portal title',
                source='1000', destination='2000', sortkey=1,
                profile='my.package:default')
def to2000(context):
    """
    Update portal title
    """
    site = context.getSite()
    site.title = u'A New Title'
