Looking for current shopping cart product
by John Schinnerer 27 May '06

27 May '06

Aloha, I am wondering if there is any current and stable shopping cart products for zope (2.7.5 is my current live version). I have a custom merchandise product for a client's business site. Retail sales are already handled via their PayPal merchant account. The retail items only need the appropriate PayPal button/form code and PayPal handles the rest. However the client also does wholesale, but not via PayPal, and wants a wholesale "cart" into which a wholesale buyer can put items and quantities to submit for review, final pricing, and shipping costs. I have just looked on zope.org and under products - commerce I don't find anything that looks current. I searched zope.org also and didn't find anything. I googled around a bit for zope shopping cart product and simliar and still didn't find anything that looked viable. Is there anything out there? If so why is it so hard to find? ;-) thanks, John S. -- John Schinnerer - MA, Whole Systems Design ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john(a)eco-living.net http://eco-living.net

I believe your httpd.conf has some problem. Specifically (and as I think suggested by others) I believe that rule is somewhere where it doesn't get executed. I suggest to comment out the "http" rules for a moment, turn on RewriteLog (e.g. pointing it to /tmp/rewritelog or something for the moment) and then look what's happening. I expect that you don't see any output... but of course I might be wrong. Please note that in my oppinion this is a problem of apache configuration, not of Zope. Regards, Sascha

By Zope objects I meant: You've got a page template for example, and you include such an "AJAX enabled object", basically rendering an HTML fragment, and the resulting page will include the page template code + the fragment (similar to a macro call), but will also include the needed javascript code to handle the asynchronous communication. Then another thing would be something like a PythonScript object (so you define python code and return python structures) and get it rendered as javascript to be included in somepage for processing the data returned by an asynchronous XML-RPC call to Zope within the browser. Does it make more sense now?

The helpers would then be some sort of Ajax JS library. I think that at this time it makes more sense to let people choose for themselves. If one turns out to be better than the others, it will spread around the community and become a "default" standard, and then maybe it's interesting to include as a standard package, but thats a big maybe and a big if. I don't know what any built-in Zope-objects would do for Ajax. :) -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/ ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

This isn't the most obvious thing from th form, but it should be a cluee that the port doesn't change when you select https. > I also found the following rule from scanning through zope-list postings, to > force any logon authentication requests to go over https.

The two rules of the witch could likely be rewritten to one, but two rules cover the two possibilities easy in a form that humans can grasp: Either the URL ends there, or else it has a slash and then as much as there is.

Not authorized to access binding
by Antonio Beamud Montero 25 May '06

25 May '06

Hi all: I'm using Zope 2.7. I have created a product that inherits from Folder. The security assertions are:: security = ClassSecurityInfo() security.declareObjectProtected('View management screens') But I need to publish some ZPT methods public. I have declared them: security.declarePublic('my_stations') my_stations = PageTemplateFile('wsdl/my_stations.wsdl.zpt', globals()) my_stations.content_type = 'text/xml' And 'wsdl/my_stations.wsdl.zpt' has only a reference to absolute_url in: ------------------- ... <port binding="tns:StationsBinding" name="port"> <soap:address tal:attributes="location here/absolute_url" location="http://localhost:8000/ccx/StationsService"/> </port> ... The problem is trying to access to this method as anonymous user gives me: ---------------------------------------------------------------- ... Module Products.PageTemplates.Expressions, line 189, in _eval Module Products.PageTemplates.Expressions, line 145, in _eval __traceback_info__: here Module Products.PageTemplates.Expressions, line 323, in restrictedTraverse __traceback_info__: {'path': [u'absolute_url'], 'TraversalRequestNameStack': []} Module Shared.DC.Scripts.Bindings, line 176, in __getattr__ Module Shared.DC.Scripts.Bindings, line 182, in __you_lose</li> Unauthorized: Not authorized to access binding: context (Also, an error occurred while attempting to render the standard error message.) ---------------------------------------------------------------- With other methods declared publics all works ok (like published via SOAP)... Can any one help me?

Migrating from PTS to Zope 2.9.3's i18n?
by Chris Withers 25 May '06

25 May '06

Hi All, (CC'ing Philipp in directly since he appears to be fairly guru-some in this area!) I have a project with a load of ZODB-based page templates that are all marked out for use with PTS. How hard would it be to sub in Zope 3's i18n stuff for PTS and, if I chose to do so, what would be the best way to go about doing it? Can the existing .pot and .po files be used? How do you generate .pot files from ZODB-based ZPT's and python scripts in Zope 2.9/Five land? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

[i18n] i18n not working in nested macros?
by Andreas Jung 24 May '06

24 May '06

I am running a Plone site with Plone 2.1.X on top of Zope 2.8.6. I have a case where base_edit calls a macro for a self-written macro which calls another helper macro. This one contains something stupid as <label i18n:translate="enddate">end date</label> However the content of the tag is never translated...all macros define i18n:plone inside the HTML tag, the tag defining the macro and also I put inside the <label> tag. When I move the <label> tag inside the macro called by base_edit then everything works fine. I also added debug code to PTS to see if there is a problem with the translation service however the related message id never shows up. I have not track this down so far inside the TAL code...anyone ever encountered such a strange behavior? Andreas

Re: [Zope] RESPONSE.redirect not working

Actually, that is exactly what is happening. It's the current URL with the contents of login_html rendered.

Well, that's why I mentioned this in my initial mail: http://jtauber.com/blog/2006/05/23/primitive_python_version_of_gwt_working (the python to javascript translator part) Of course I know how to make some AJAX to in Zope for some specific application. But I wanted to know if some of the core Zope developers had ever thought about a more generic approach. For example I am sure that having this "python to javascript translator" and objects like PythonScripts that would have a "javascript" view is something that would make AJAX enabled pages development on Zope much easier (just a matter of including the JS library and then make some python code).

That is a macro call. There is no difference.

Thare has been discussions and efforts to make a library where you can write python code and get Ajax out, yes.

AJAX and Zope
by Pascal Peregrina 24 May '06

24 May '06

Hi, I was wondering if there is any plan to have built-in support (i.e. helpers, built-in Zope objects, etc) in order to support AJAX in Zope at some point. Zope is already XML-RPC compliant, so it should not be very difficult to do so... Has anyone seen this? http://jtauber.com/blog/2006/05/23/primitive_python_version_of_gwt_worki ng Pascal ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
