Use of the different displays with Imagemagick.
by William GARCIA 06 May '02

06 May '02

ImageMagick is installed on the server I work. When I create a Photo product instance, if I see the properties of the image, several displays have been generated. I would like to display a thumbnail with :<dtml-var expr="image(display='thumbnail')"> but Zope generated the next error : Error Type: AttributeError Error Value: __call__ Traceback (innermost last): File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 114, in publish File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: test_photo_imagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 98, in publish File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval (Object: image(display='thumbnail')) (Info: image) File <string>, line 2, in f Thanks in advance for the help you can give to me.

no traverse_subpath
by Scott Pierce 06 May '02

06 May '02

I am writing a product that relize heavily on traverse_subpath. I recently branched off my cvs and redesigned to make better use of acquisition. However, suddenly there is no traverse_subpath in the REQUEST object. Any ideas on where 'traverse_subpath' might have gone and why it disappeared? If I create a simple dtml method and call it w/ <dtml-var REQUEST> it isn't there. ===== Scott "Liberty has never come from the government. Liberty has always come from the subjects of government.

Can I do this in a python products ??
by Nicolas Évrard 06 May '02

06 May '02

Hello, everyone, Since this is my first post on this lis, I will introduce myself shortly. I'm a developper in a small enterprise which has a huge internet project, since I am a great user of linux and of python I naturally tough about doing all my job in Zope. At first I played with dtml-scripting and so on. But now I'd like to make a little product and when I'll be fluent in this kind of programming, I will migrate the whole site to Product-like programming. Now, my question : I do this in the initialization of my product : fd = open('the_file') line = fd.readline() while line : process_line(line) line = fd.readline() The file 'the_file' is in the base directory of the product but I keep getting 'No such file'. I then decided to put this file on the Zope Directory where my product will be localized but the same problem arose. Is it possible to have some kind of a rc-file for a product the need to be parsed (this file residing either in the product directory or in the zope directory). Maybe I'm all wrong and that's not the way I ought to think in Zope ... -- Évrard Nicolas SOLIREM SA - Projet Smartainers 1, rue de l'épervier Tel: +32 4 248 08 85 B-4040 Herstal Fax: +32 4 248 05 78

installing python MySQL/ZMySQLdb on FreeBSD
by davis marques 06 May '02

06 May '02

hi Andy; I've been trying to get your MySQL-python and ZMySQLdb products to run on my FreeBSD Zope setup and have had no luck thusfar. I'm wondering if you've received any feedback from your FreeBSD users on successful setup procedures? Zope doesn't seem to like the _mysql.so file and responds with "...site-packages/_mysql.so: ELF file OS ABI invalid" Some searches on Google suggest that this is a problem of using a Linux library on a BSD machine, however I've upgraded the libraries to the latest versions using packages from BSD themselves and am still having the same problem. Any workarounds you could suggest would be appreciated. thanks Davis Marques zope error message --- 2002-05-06T21:30:23 ERROR(200) Zope Could not import Products.ZMySQLDA Traceback (innermost last): File /usr/local/Zope-2.5.1-linux2-x86/lib/python/OFS/Application.py, line 531, in import_product File /usr/local/Zope-2.5.1-linux2-x86/lib/python/Products/ZMySQLDA/__init__.py, line 91, in ?

How to import files via FTP and set attributes.
by Gary Speer 06 May '02

06 May '02

I'm mildly experienced at Zope, yet haven't found the 'simple' way to execute the following. I been going in circles on this and all suggestions as to how to approach the problem would be appreciated. Rather than correct the approaches I have been trying, I think it best to get a fresh perspective. Big Picture Objective: User FTPs a batch of files into an empty zope folder along with a text document called contents.txt. contents.txt has one line per uploaded file in CSV or similar parseable layout that begins with the file name. After the upload, the user triggers a posting process (a 'process the upload' form buttom with Action=Do_It(). The executed Do_it object reads the text file and loops once per line, for each line, it parses it into a file name and several attributes. The object then writes the uploaded file content to a target folder as a zope object having these attributes. I am stuck at looping on and parsing the content of the contents.txt file to get and pass the attributes to the add object method. I figure the solution is best executed with Python in the context of Zope, but I'm stuck at figuring out the syntax for this namespace. 1) syntax to loop on the content of a file, one line at a time. 2) string syntax to parse the line into variables (I don't think an array is needed.) 3) modify object syntax to update each file's attributes with the variables (or add a new object such as an image object with the imported file's contents.) Suggestions, syntax, or pointers to how-tos all gratefully accepted. Thank you! Gary

Testing for duplicate ZODB records
by Michael 06 May '02

06 May '02

I've looked through the "Zope Book","Web Application Development and Content Management", the Zope How to's and every source I can think of and still can't seem to find how to test for duplicate records in ZODB. As it is right now, I can enter 100 records that are exactly the same, except for their id number. Can anyone point me to a resource that explains how to do this?? I'm using a form to gather the data to be entered, then it calls a record processor that sets the values and creates the record.ie: ---------------------------------------------------------------- form name="some_form" action="record_processor" input type="text" name="user_fname" value="" input type="text" name="user_lname" value="" input type="text" name="user_email" value="" input type="submit" name="submit" value="Submit" ---------------------------------------------------------------- (record_processor) <dtml-call "REQUEST.set('user_fname', user_fname)"> <dtml-call "REQUEST.set('user_lname', user_lname)"> <dtml-call "REQUEST.set('user_email', user_email)"> <dtml-call "REQUEST.set('title', user_lname+' - '+user_fname+' -'+user_email)"> <dtml-with "manage_addProduct['UserInfo']"> <dtml-call "user_info_entry_add(_.None, _, NoRedir=1)"> </dtml-with> <dtml-var nice_little_acknowledgement_message> Thanks, Michael

decaring a list in python
by Ed Colmar 06 May '02

06 May '02

Hey everyone. I've got an easy one here, but it's got me somewhat confused... I declare in my product: self.skins_loaded = ['default', 'minimal'] when I use it in a <dtml-in> I get "strings are not allowed". Ok, fine, so I go to my edit form, which is marshalling "skins_loaded:lines" and I put them on two lines.... Then it works as it should... How can I get this to happen from the start? I must be missing something really obvious. thanks for any clues! -e- -- Green Graphics ::: Print and Web Design ::: 510.923.0000
