zc.recipe.filestorage 1.0a2

This recipe can be used to define a file-storage. It creates a ZConfig file-storage database specification that can be used by other recipes to generate ZConfig configuration files.

This recipe takes an optional path option. If none is given, it creates and uses a subdirectory of the buildout parts directory with the same name as the part.

The recipe records a zconfig option for use by other recipes.

We’ll show a couple of examples, using a dictionary as a simulated buildout object:

>>> import zc.recipe.filestorage
>>> buildout = dict(
...   buildout = {
...      'directory': '/buildout',
...      },
...   db = {
...      'path': 'foo/Main.fs',
...      },
...   )
>>> recipe = zc.recipe.filestorage.Recipe(
...                   buildout, 'db', buildout['db'])

>>> print buildout['db']['path']
/buildout/foo/Main.fs

>>> print buildout['db']['zconfig'],
<zodb>
  <filestorage>
    path /buildout/foo/Main.fs
  </filestorage>
</zodb>

>>> recipe.install()

>>> import tempfile
>>> d = tempfile.mkdtemp()
>>> buildout = dict(
...   buildout = {
...      'parts-directory': d,
...      },
...   db = {},
...   )

>>> recipe = zc.recipe.filestorage.Recipe(
...                   buildout, 'db', buildout['db'])

>>> print buildout['db']['path']
/tmp/tmpQo0DTB/db/Data.fs

>>> print buildout['db']['zconfig'],
<zodb>
  <filestorage>
    path /tmp/tmpQo0DTB/db/Data.fs
  </filestorage>
</zodb>

>>> recipe.install()

>>> import os
>>> os.listdir(d)
['db']
