easyshop instance creating problem

[Alex Zhang]

Hi,

I'm sorry to bother you because of the easyshop install problem.
I'm learning to build a web shop based on plone 3.3.1
Today I follow the introduction linked from:
http://code.google.com/p/easyshop-for-plone/wiki/StartToEndTutorial
step by step, I ssuccess to show the easyshop on my products list:
EasyShop 0.1a1dev-r1704
An out-of-the-box online-shop for Plone.
Install log for easyshop.core
Status
installed
Transcript
2010-05-31 08:44:40Installed via setup tool
But when I click the "Add New.." button, I can't get an "Easyshop"
item in the Add New drop down menu.
Could you please help me to check the reason and find solution?

Thanks for your help.

Best Wishes

Can you supply some Zope logs from the point of starting Zope after
modifying your buildout to include Easyshop?

And you're definitely adding Easyshop to buildout, running buildout,
starting Zope, adding a new Plone website, installing the Easyshop
product in that new Plone website, then trying to add a new Easyshop
on the front page of the new Plone website?

Well this isn't really the forum for step by step guides on how to use
Zope. However, your buildout.cfg will specify where Zope should put
its logs. On a ZEO cluster they'll default to <buildout dir>/var/
client?/ and they'll be called event.log and Z2.log. You simply search
through these and copy & paste the relevant sections.

Hi,

Maybe, you need to try Products.DataGridField-1.6.1 instead of 1.7.

Kind regards,

Hi Loc,

It's the way to fix the problem maybe.
Anyway I will try.
But how can I uninstall the Products.DataGridField 1.7? Or need to
uninstall both easyshop together with Products.DataGridField 1.7?
Please guide me to do the above with thanks

Hi,

Download DataGridField here http://plone.org/products/datagridfield/releases/1.6.1/Products.DataGridField-1.6.1.tar.gz
If you followed the tuto StartToEndTutorial for EasyShop, you need to extract DataGridField in the src directory, the same where is DataGridField-1.7 and change the buildout.cfg

develop =
    ...
    src/Products.DataGridField-1.6.1	

instead of

develop =
    ...
    src/DataGridField-1.7

just add the following to your buildout.cfg under the eggs section:

[versions]

Products.DataGridField = 1.6.1

;)

Indeed, the tutorial says to install DataGridField in src/ just like
this in its Introduction. But the other way of pinning its version via
buildout.cfg works fine too.

I just realised that people were suggesting to replace DataGridField
1.7 with 1.6.1. I haven't personally noticed the need to do that here,
but I am running Plone v3.3.4 which if I remember its changelog did
fix an earlier incompatibility with newer versions of DataGridField.
If I remember the OP was running v3.3.1 or something which is fairly
old nowadays.

Hopefully this explains the problem.

Thanks all,

I have tried to install easy shop based on DataGridField-1.6.1 on
plone 3.3.1
But the result is same
Could add the easyshop products but could not show under Add new...
list
It's crazy.
How can I do now?
Iis it run well in Plone 3.3.4 right?
Maybe the only way is update my plone to 3.3.4?

That is unexpected given the error in your logs which definitely
showed the problem to be in DataGridField.

It may be worth doing a temporary clean install on a local virtual
machine i.e. install VirtualBox, install Ubuntu Server on it or
whatever and install Plone onto that and then Easyshop into that. It's
always worth having an rsynced copy of a Plone site on a local VM
anyway, then you can test before you push changes.

I will say don't try Easyshop with Plone 4. It won't work.

HTH,
Niall
