Resizing an Image with PIL via a Form Upload
by Tom Von Lahndorff 23 Feb '07

I'm trying to resize an image uploaded from a form using PIL. I got it to work on an existing image but I can't seem to get it to work on an image that's uploaded through the form. The ID of the file I'm trying to upload is "DSCF0004.jpg". The form, script and traceback are listed below. Thanks in advance. <form action="processed/imgSizer" method="post" enctype="multipart.form-data"> <input type="file" name="original_id"> <input type="submit" name="submit" value=" Add "> </form> (imgSizer External Method) 1 def makeImages(self, original_id): 2 3 import PIL.Image 4 import PIL 5 from StringIO import StringIO 6 import os.path 7 8 original_image=getattr(self, original_id) 9 original_file=StringIO(str(original_image.data)) ... returns: Traceback (innermost last): * Module ZPublisher.Publish, line 115, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 41, in call_object * Module Products.ExternalMethod.ExternalMethod, line 225, in __call__ __traceback_info__: ((<Folder at /dev/imgtest/processed>, 'DSCF0004.jpg'), {}, None) * Module .../Zope/Extensions/imgSizer.py, line 9, in makeImages AttributeError: DSCF0004.jpg

How to create a global variable?
by jerome prudent 22 Feb '07

22 Feb '07

Hi! I've a python script which creates a dictionnary each time it's called. This dictionnary is always the same. I would increase the performance if I could generate and cache the dictionnary once, then reuse it. I'm looking for a space like REQUEST.SESSION that is the same for each user of my website (other solutions are welcome). Do you know how to do that? Thank you.

metal:fill-slot and tal:condition
by Dragos Chirila 22 Feb '07

22 Feb '07

Hi everybody, I am stuck with the following problem. I would appreciate it very much if you could help me with it. So I have a ZPT where a macro is defined with several slots; one of the slots like below: <tal:block metal:define-slot="slot_issue"> SLOT DEFAULT CONTENT </tal:block> The common way to put other content in the slot is: <tal:block metal:fill-slot="slot_issue"> CUSTOM SLOT CONTENT </tal:block> Now, in a ZPT that uses the above marco I want to replace the default slot content with other stuff *only* if a condition is fulfilled: <tal:block tal:condition="<condition-code>" metal:fill-slot="slot_issue"> CUSTOM SLOT CONTENT </tal:block> If the <condition-code> returns True then the "CUSTOM SLOT CONTENT" is put instead of the default slot content - correct. If the <condition-code> returns False then nothing will be displayed - this is not correct?!. I also tried somthing like: <tal:block tal:condition="<condition-code>"> <tal:block metal:fill-slot="slot_issue"> CUSTOM SLOT CONTENT </tal:block> </tal:block> In this case the content of the slot is "CUSTOM SLOT CONTENT" in both cases - the result is True or False. The only solution that I can think of is not elegant at all because I have to duplicate the slot_issue's default content: <tal:block metal:fill-slot="slot_issue"> <tal:block tal:condition="<condition-code>"> CUSTOM SLOT CONTENT </tal:block> <tal:block tal:condition="python:not <condition-code>"> SLOT DEFAULT CONTENT </tal:block> </tal:block> Is there other wat to accomplish this? Thank you very much, Dragos

Copy and Paste Problem
by Florian Fahrbach 21 Feb '07

21 Feb '07

Hi all, I hope somebody knows an answer to my rather strange problem. It seems that in our Zope-Installation (2.74) we screwed up the Copy/Cut/Paste-Mechanism. We can not copy any objects in the ZMI at all. The result always is, that the same object ist pasted several times (Paste-Button stays at the bottom of the ZMI) or a copy error occurs. When we empty the caches/cookies etc. of the browser and restart it, we can copy one object, before the same behaviour starts again. Does anyone know what the problem could be? Thank you for your help. Greetings from Germany, Florian

How about changing the following line 996 in /lib/python/zope/publisher/http.py ( as described in http://www.zope.org/Collectors/Zope/2280 ) header_present = 'HTTP_ACCEPT_CHARSET' in self.request to header_present = 'HTTP_ACCEPT_CHARSET' in self.request.keys() I think this is a bug. After doing that change, IE6 and IE7 behaved consistently. Regards Jost --------------------------------- Need Mail bonding? Go to the Yahoo! Mail Q&A for great tips from Yahoo! Answers users.
