1   Importing Themes

Concept code showing how to install themes saved in XML format from the filesystem (requires CPSIO >= 0.3.0)

• 'filepath' is the path to the file on the local filesystem.
• 'filename' is the file's name (e.g. 'theme.zip').

Sample code:

from Products.CMFCore.utils import getToolByName
from ZPublisher.HTTPRequest import FileUpload

class DummyFileUpload:
    def __init__(self, **kw):
        for k, v in kw.items():
            setattr(self, k, v)

class Installer:
    """ a product installer """

    def installTheme(self, filepath='', filename=''):
        """Install a theme (XML)
        """
        tmtool = getToolByName(self, 'portal_themes')

        fs = DummyFileUpload(
            file=open(filepath, 'r'),
            headers={'Content-Type': 'application/zip'},
            filename=filename)

        tmtool.manage_xmlImport(
            FileUpload(fs),
            options=['import_overwrite'],
            plugin='CPSSkinsImporter')

2   Configuring Theme Settings

Theme settings can be imported with CPSIO (> 0.3.?).

To import theme settings, use the same code as above with the following parameters:

....
tmtool.manage_xmlImport(
    FileUpload(fs),
    options=['import_theme_settings'],
    plugin='CPS3Importer')
....

3   Example Code

Some functional code ready to be inserted in your install.py script. (requires CPSIO and CPSInstaller):

from Products.CPSInstaller.CPSInstaller import CPSInstaller

class DummyFileUpload:
    def __init__(self, **kw):
        for k, v in kw.items():
            setattr(self, k, v)

class ProductInstaller(CPSInstaller):
    """ Installer class
    """

    def package_home(self, name):
        """Returns path to Products.name"""
        m = sys.modules['Products.%s' % name]
        return (m.__path__[0])

    def install(self):
        """
        - 'default.zip' is a theme
        - 'settings.zip' are theme settings

        they are located in the 'themes/' folder of your product.
        """"

        # install the theme
        self.installTheme('default.zip')

        # install the theme settings
        self.installThemeSettings('settings.zip')


    def installTheme(self, theme=''):
        """Install a theme (XML)"""

        themesdir = os.path.join(self.product_home, 'themes')
        filepath = os.path.join(themesdir, theme)

        tmtool = self.getTool('portal_themes')
        fs = DummyFileUpload(
            file=open(filepath, 'r'),
            headers={'Content-Type': 'application/zip'},
            filename=theme)
        tmtool.manage_xmlImport(
            FileUpload(fs),
            options=['import_overwrite'],
            plugin='CPSSkinsImporter')
        self.log('Importing theme %s' % theme)


    def installThemeSettings(self, filename):
        """Install theme settings (XML)"""

        themesdir = os.path.join(self.product_home, 'themes')
        filepath = os.path.join(themesdir, filename)

        tmtool = self.getTool('portal_themes')
        fs = DummyFileUpload(
            file=open(filepath, 'r'),
            headers={'Content-Type': 'application/zip'},
            filename=filename)
        tmtool.manage_xmlImport(
            FileUpload(fs),
            options=['import_theme_settings'],
            plugin='CPS3Importer')
        self.log('Importing themes settings %s' % filename)
