I have a Plone site which I recently updated from some 4.3.3-based version to 4.3.15 (which needed to be done in any case, of course); I'd like to replace my proprietary shop development by the integration of
bda.plone.shop. My roadmap looks like this:
- Update to 4.3.15 (done, as far as the buildout is concerned; possibly still fixes in my code necessary)
- Installation of
bda.plone.shop(done, with a little 4.3 compatibility fix)
- Make existing content buyable, based on bda.plone.shop
- Replace my existing order/booking system by the use of bda.plone.shop
So far I was able to install
bda.plone.shop, but sadly not all components do work; e.g., if I visit the shopping cart (
@@cart), I see a traceback in the shell window which tells me that somehow the
portal_languages tool has been seeked and not found:
Traceback (innermost last): Module Products.PloneFormGen.patches, line 21, in safe_render Module Products.Five.browser.pagetemplatefile, line 125, in __call__ Module Products.Five.browser.pagetemplatefile, line 59, in __call__ Module zope.pagetemplate.pagetemplate, line 132, in pt_render Module zope.pagetemplate.pagetemplate, line 240, in __call__ Module zope.tal.talinterpreter, line 271, in __call__ Module zope.tal.talinterpreter, line 343, in interpret Module zope.tal.talinterpreter, line 533, in do_optTag_tal Module zope.tal.talinterpreter, line 518, in do_optTag Module zope.tal.talinterpreter, line 513, in no_tag Module zope.tal.talinterpreter, line 343, in interpret Module zope.tal.talinterpreter, line 819, in do_loop_tal Module zope.tales.tales, line 685, in setRepeat Module zope.tales.tales, line 110, in __init__ Module bda.plone.shop.browser.navigation, line 199, in links Module bda.plone.shop.browser.navigation, line 106, in lookup_navigation_items Module bda.plone.shop.browser.navigation, line 104, in unsorted_items Module zope.component.registry, line 250, in getAdapters Module bda.plone.shop.browser.navigation, line 659, in __init__ Module bda.plone.shop.browser.navigation, line 165, in context_is_default_page Module Products.LinguaPlone.browser.defaultpage, line 23, in getDefaultPage Module Products.CMFCore.utils, line 10, in check_getToolByName Module Products.CMFCore.utils, line 120, in getToolByName AttributeError: portal_languages
When I have a look in the ZMI, the
portal_languages tool is clearly there; in a
bin/instance debug session:
>>> from Products.CMFCore.utils import getToolByName >>> language_tool = getToolByName(app.plone, 'portal_languages') >>> language_tool.getSupportedLanguages() ['de', 'en']
So it looks to me like
getToolByName is called in a wrong way somewhere, and I wonder about the reason.
bda.plone.shop code makes assumptions about package versions which are not pinned for Plone 4.3.x?
This sounds likely to me, since a little fix (pull requested, discussed, enhanced and accepted) has been necessary to make Zope start again with
Any help is appreciated - thank you!
