python script executing twice?
by Karen Yang 30 Sep '02

30 Sep '02

I have an 'Add Item' form which allows the user to add item information, as well as upload a file. I have a python script that processes the form, but I'm getting some weird behavior because it seems to be executing twice. I know this because it gives me an integrity error; meaning, it has executed my insert query twice. I feel there is something wrong with my script because when I comment out the block that processes the image upload (in boldface red below), I don't get the integrity error. In addition, when I test the script in the 'Test' section, it works. I would appreciate any ideas you may have. The code is pasted below. Thank you very much. ####Python Script -- processAddItem #### #parameters: code, description,cost_code,transfer_id=None, origin, location, remarks,itemImage #process form with item details and image upload from Products.PythonScripts.standard import url_quote REQUEST=context.REQUEST #insert try here #call insert zsql method context.InventoryDB.insertItem(code=code, description=description, cost_code=cost_code, transfer_id=transfer_id, origin=origin, location=location, remarks=remarks) #query for id so that you can name image that results = context.InventoryDB.getByCode(code=code) imageId = -1 for item in results: imageId = item.id break if itemImage != None: content_type=itemImage.headers['Content-Type'] if content_type.find('image')!=-1: context.images.inventory.manage_addProduct['OFSP'].manage_addImage(id=str(imageId), file=itemImage, title='') else: context.images.inventory.manage_addProduct['OFSP'].manage_addFile(id=str(imageId), file=itemImage, title='') # create a success message message="Item '%s' added successfully." % code # redirect to main page - this is necessary to make all the URLs # on the main page work correctly. return context.REQUEST.RESPONSE.redirect("%s?message=%s" % (container.absolute_url(), url_quote(message))) #### Page Template code:#### <form action="processAddItem" method="POST" enctype="multipart/form-data"> <span class="errorMessage" tal:condition="options/error_message | nothing" tal:content="options/error_message"> Error Message </span> <table class="text" style="font-weight:bold" cellspacing="2" cellpadding="2" border="0"> <tr> <td><font size="1" font-family="tahoma" color="red">*required fields</font></td> </tr> <tr> <td>Code:<font color="red">*</font></td> <td><input type="text" name="code:required"></td> </tr> <tr> <td>Description:</td> <td><input type="Text" name="description"></td> </tr> <tr> <td>Cost Code:</td> <td><input type="text" name="cost_code"></td> </tr> <tr> <td>Transfer Id:</td> <td><input type="text" name="transfer_id:int:ignore_empty"></td> </tr> <tr> <td>Origin:</td> <td><select name="origin" class="text"> <option value="">None</option> <option tal:repeat="branch container/getBranchList" tal:content="branch" tal:attributes="value branch"> branch </option> </select> </td> </tr> <tr> <td>Location:</td> <td><select name="location" class="text"> <option tal:repeat="branch container/getBranchList" tal:content="branch" tal:attributes="value branch"> branch </option> </select> </td> </tr> <tr> <td>Remarks:</td> <td><textarea cols="30" rows="10" name="remarks"></textarea></td> </tr> <tr> <td>Image:</td> <td><input type="file" name="itemImage"></td> <tr> <td> </td> <td> <input type="submit" name="submit" value="Add Item"></td> </tr> </table> </form> --------------------------------- Do you Yahoo!?

Hi Michael Look at the LocalFS product - it lets you link to files on the operating system. http://sourceforge.net/projects/localfs If you need to link to another PC, I spose you could map that remote location to a drive then link to that drive. -----Original Message----- From: michael.tañag [mailto:almightymike@yahoo.com] Sent: Monday, 30 September 2002 3:35 p.m. To: zope(a)zope.org Subject: [Zope] Get files from outside zope Hi! how can I get my DTML document to have a link outside zope, like linking to a file on another PC but on the same netwrok?

applets and Zope?
by Dennis Allison 30 Sep '02

30 Sep '02

I've been trying to get an exemplar to work and could use a bit of advice. The applet and associated Java mechanisms are stored in the external file system and made visible to Zope through the External Filesystem product. The Java Applet and associate HTML are stored in a DTML Document and referenced by a DTML method that renders it using <dtml-var>. It sorta works, but the applet can't seem to find some of the Java Classes it needs, even thought they appear in the external file system. I have codebase, code, and archive set correctly. I have a Zope External File System folder, XXX, that contains the applet, some supporting classes, and an archive. The actual HTML code referencing the applet is also stored there. In the applet, codebase is set to the Zope URL of the folder: http://...../XXX/ code is set to the parent Java class foo.class and archive is set to the URL of the archive http://....../XXX/foo.jar The html code invoking the applet is called with a normal dtml-var (name, not expr). It appears to render properly and sets off the Java system, invokes foo.class, and then dies with a NoClassDefFound error. The class is clearly present at the same level as foo.class, but apparently something has confused the reference mechanism. I've not used applets in the Zope environment before. I am not sure whether what I'm doing is the right thing--clearly there is something wrong since the Java system can't find the right stuff. Is there an applet how-to? What should I try next? The output from the Java console (Netscape 4.7) is not all that useful...

Re: [Zope] Re: plone "vs." CMF was ... uPortal?? (fwd)

Even if it's not positive > then you might like to respond to this thread. > I'd really like to see cross-fertilisation between > uPortal and Zope ..... but if it's a non-starter then > people should tell me! [I am sending this to the Zope list as well] Well, to begin with, I haven't studied much of uPortal yet, apart from reading some of the specs and following the uPortal mailinglist. I am scheduled to attend an uPortal advanced class in Stockholm, Sweden on October 15-17 , and I expect to understand it more after that ;) uPortal does have a strong line of followers among our fellow universities in Sweden, and is, I believe, generally seen as a solid ground on which to base current and future portal enterprises - and not only for each university in isolation, but also in cooperative projects. There is an informal group working whose goals is to share code and solutions among universities, since we all share the same domain of problems, needs and solutions. Though I don't know if we (Chalmers University of Technology) hold an official view of uPortal, there is an interest from both myself, my managers and our CIO, and we view uPortal as a strategically important technology. If we end up using it or not is still an open matter. We are, however, aware of the possibilities. In general, I am very appealed by uPortals idea of channels, which kind of fits perfectly into that slot in my mind that gets all jumpy by the idea of somehow being able to "assemble" software from a set of standard components, making the result larger than the sum of it's components. For some reason, uPortal resembles the kind of framework I thought Zope was when I decided to use Zope for our apps, about 2 years ago. We have invested a lot into Zope and the LMS application we have built which , based on my (very) biased impression, is one of the most complete LMS's in use in Sweden so far ;). We are not likely to drop Zope and replace it with uPortal just yet; instead we will probably try to do what Paul Browning has suggested, use Zope as a content driver/channel in uPortal. I (reluctantly) agree that it doesn't really makes sense to re-implement uPortal in Zope, since it is allready there ready to use and I find Paul's insight on using Zope together with uPortal comforting since it allows for good use of both worlds. > > > > What I'd like to see in the CMF/Plone kit is some uPortal-like > > functionality.

I don't know much/enough about the CMF but I'm sure this > is all do-able. But if uPortal have already invented that wheel .... > IMOH, this would be where I think it might make most sense to implement uPortal-like functionality in Zope - not to have a "zuPortal", but to improve either the way Zope works and/or how products are written, more like components; however, this is a very personal opinion based on "gut feeling" mostly, as I have not had the time to really grok Zope's code-base... In any event I think that mixing Zope with uPortal might give us a competitive edge that is hard to beat - many of the channels available for uPortal are commercial ones, and I think it is reasonable to expect that a decent OpenSource (or commercial for that matter) CMS channel in Java for uPortal will take it's time to arrive. This is where Zope has it's window of opportunity. Also, let's not forget that for many small apps, setting up a Zope, buidling the app and publishing it in uPortal is probably less painfull than doing it entirely in Java. Anything that Zope provides OOB that allows you to focus on the task at hand, you will have to build in Java before doing solving the actual problem...

Accsessing the folder above
by Sebastian Queißer 29 Sep '02

29 Sep '02

Hi! I'm trying to display all folders in the folder above my product(derived from a folder) in a tree. It must be something like this: <dtml-tree branches_expr="Subfolder.objectValues(['Folder'])"> ... </dtml-tree> The problem is, that this doesn't work. I search something for "Subfolder", which includes the folder above. It works with the name of the Folder, but I want to use the product in every folder without changing it every time. Thanks Sebastian

Easy <dtml-sendmail> syntax question.
by Derek Basch 29 Sep '02

29 Sep '02

Hello, I have been playing with dtml-senmail for the first time and I have gotten stuck on something. I have a DTML Method named 'send_email_setup' with: _____________________________________________ <dtml-var standard_html_header> <form action="send_email"> SMTP Host: <input type="text" name="smtphost"><br> Send To: <input type="text" name="recipient"><br> Subject: <input type="text" name="subject"><br> <input type="submit"> </form> _____________________________________________ which calls the 'send_email' DTML Method: _____________________________________________ <dtml-var standard_html_header> <dtml-sendmail smtphost=<dtml-var smtphost>> To: <<dtml-var recipient>> From: Server <<dtml-var SERVER_URL>> Subject: <<dtml-var subject>> </dtml-sendmail> _____________________________________________ I cant save the 'send_email' mehtod so know I am doing something wrong by nesting the <dtml-var smtphost> inside <dtml-sendmail>. Can anyone tell me how to do this properly? Thanks, Derek Basch __________________________________________________ Do you Yahoo!? New DSL Internet Access from SBC & Yahoo! http://sbc.yahoo.com

Re: [Zope] installing ReportLabs
by Dennis Allison 29 Sep '02

29 Sep '02

Thanks for your help. Since the instructions in the rlzope readme.txt were so specific, I'd assumed that the path was set automagically. A slight change to the doc would be helpful ''' 1 - Install reportlab in the Zope/lib/python/Shared directory by unpacking the tarball and putting a reportlabs.pth file in site-packages for the Zope used with Python. The path value in the reportlabs.pth file must be relative. For a typical Zope installation, the path is "../../python/Shared". Remember to restart Zope so the new path is instantiated. '''
