Question

I have a Plone site (Plone version 3.1.2) that I need to install a product called GrufSpaces on - (http://plone.org/products/grufspaces). However, it is a production site and so I can t easily take it down to upgrade Plone to 3.2+ in order to use buildout; using buildout would allow me to easily add Grufspaces (collective.groupspace.roles etc) as a Product.

I have downloaded the egg files separately (roles, workflow, mail, content) and placed them in a directory structure like so:

collective/
- __init__.py
- groupspace/
  - __init__.py
  - content/...
  - roles/...
  - workflow/…
  - mail/...

What I thought I could do is add this "collective" folder to [plone directory]/Zope/lib/python as a Python module. The idea being once its added I can restart Plone/Zope and it will automatically pick it up and make it available within Plone as a Python Module. Unfortunately it has not worked as of yet.

If I am going about this the wrong way I welcome any suggestion to try this a different way.

Answer 1

If you are trying to install GrufSpaces 2.0 then you should consider upgrading to Plone 3.3 (see the install requirements)

Placing the collective.* packages to [plone directory]/Zope/lib/python should work. But these packages are not compatible with Plone 3.1. Here is the example of ImportError that I get when using collective.groupspace.roles with Plone 3.1:

  File "/home/andrey/tmp/zope/instance/lib/python/collective/groupspace/roles/browser/roles.py", line 23, in ?
    from plone.app.workflow import PloneMessageFactory as _
zope.configuration.xmlconfig.ZopeXMLConfigurationError: File "/home/andrey/tmp/zope/instance/etc/site.zcml", line 15.2-15.23
    ZopeXMLConfigurationError: File "/home/andrey/tmp/zope/instance/Products/GrufSpaces/configure.zcml", line 17.4-17.53
    ZopeXMLConfigurationError: File "/home/andrey/tmp/zope/instance/lib/python/collective/groupspace/roles/configure.zcml", line 7.4-7.34
    ZopeXMLConfigurationError: File "/home/andrey/tmp/zope/instance/lib/python/collective/groupspace/roles/browser/configure.zcml", line 5.4-10.10
    ImportError: cannot import name PloneMessageFactory

Besides collective.* packages you have to download GrufSpaces product from SVN (download link at plone.org doesn t work for me) and place it in Products folder.

Answer 2

Did you check GrufSpaces INSTALL.TXT? From there:

Unpack it into your Zope Products Folder

For Plone, the easiest way is probably to unpack it the top level products folder.

See also http://plone.org/documentation/kb/third-party-products/installing, section "Installing Zope 2-style Products Without Buildout".

Answer 3

No advice specific to GruffSpaces as I ve never used it but it sounds like you may be under the mistaken impression that you need Plone 3.2+ for buildout. This is incorrect. Buildout works just fine with Plone 3.1.2. I ve also done buildouts for Plone 2.5.5 and even one for Plone 2.1 (although this last one was a bit tricky because the required python for that version doesn t do buildout).

So if you prefer the buildout route, just do it. Although upgrading your Plone is probably still good advice.
