Project Description
Persistent Cheetah templates


- Cheetah template engine,
- sources in filesystem,
- stored in ZODB,
- editable TTW, simple "$var" Cheetah syntax for non-technical user,
- able to testing in management web-form,
- able to reset from source.

Use cases:

- mail templates,
- editable HTML snippets and pages,
- other.

* Needed imports for these tests *

>>> import os, tempfile
>>> temp_dir = tempfile.mkdtemp()

>>> import zope.component
>>> import ice.template

>>> from zope.configuration import xmlconfig
>>> context = xmlconfig.file('meta.zcml', ice.template)

Create templates

1) Create source file using Cheetah syntax "$" for the variables::

>>> file = os.path.join(temp_dir, 'welcome.tmpl')

>>> open(file, 'w').write('''
... Dear $user_name!
... Welcome to $site_name!
... ''')

2) Register template::

>>> context = xmlconfig.string('''
... <configure
... xmlns=""
... xmlns:ice=""
... i18n_domain="test">
... <ice:template
... name="welcome"
... title="Welcome"
... storage="my-templates"
... source="%s"
... variables="user_name
... site_name"
... />
... </configure>
... ''' % file, context=context)

Create storage

Need create (one or more) local utility to store templates.
Note, the utility name used for lookup the storage::

>>> templates = ice.template.Templates()

>>> zope.component.provideUtility(
... templates, ice.template.ITemplates, 'my-templates')


Use template::

>>> data = {'user_name':u'Bob', 'site_name':''}

>>> templates.compileTemplate('welcome', data)
'\n Dear Bob!\n Welcome to!\n'

Manage templates

Looking all templates, registered for this storage::

>>> list(templates.getAllTemplates())
[(u'welcome', <ice.template.zcml.template object="" at="" ...="">)]

Get variables names::

>>> templates.getVariables('welcome')
[u'user_name', u'site_name']

Get template::

>>> templates.getTemplate('welcome')
'\n Dear $user_name!\n Welcome to $site_name!\n'

Edit template::

>>> templates.setTemplate('welcome', "$site_name for you, $user_name")

>>> templates.compileTemplate('welcome', data)
' for you, Bob'

Reset from source::

>>> templates.resetTemplate('welcome')
'\n Dear $user_name!\n Welcome to $site_name!\n'

>>> templates.compileTemplate('welcome', data)
'\n Dear Bob!\n Welcome to!\n'

Using property

Another way to use special property::

>>> class Pagelet(object):
... template = ice.template.PersistentTemplate('my-templates', 'welcome')
... def update(self):
... = {'user_name':'Man', 'site_name':''}
... def render(self):
... return self.template(

>>> view = Pagelet()
>>> view.update()
>>> view.render()
'\n Dear Man!\n Welcome to!\n'

Management UI

Management persistent Cheetah templates UI based on z3c.pagelet layers.

There are 3 views for management templates:

1) Listing of all storages.
2) Listing of all templates in a storage.
3) Edit form for given template, reload, testing, preview.

Actually, you need to do only one: register listing of all storages
pagelet using class ice.template.browser.storages.Pagelet (see example
in configure.zcml in ice.template.browser module), because (2) and (3)
are already registered. For examples, take a look configure.zcml
in ice.template.tests module.
