auto download link
by Jerry 17 Feb '04

17 Feb '04

Hi Zopeople, I have some python files that I want users to be able to download. I would like them to be able to click on the anchor and start downloading. I must be missing something fundamental in Zope or HTML. I cannot figure out how to *download* the file instead of display it. I have tried creating a File object and DTML Document, tried changing the Content Type to application/msdownload (and about 20 other types). I have used DocFinder and tried all kind of method names (looking for the inverse of 'document_src'). Is there a way to force the download action instead of rendering? -- Jerry (Mailed safely with The Bat! 2.02.3 CE) ___________________________ Nobody can be un-cheered with a balloon.

Strange problem about Catalog
by Star War 17 Feb '04

17 Feb '04

Hi, Can anybody help me to solve this problem? After recataloging the whole web site, I found a very strange problem: it takes about 10 seconds to access a page that may be dynamically generated by DTML methods using catalog. But it is very fast if you just access a static page in the same site by giving url directly. So I guess it is caused by catalog. I search the list for an answer, but I still don't know how to solve it. My zope server is old, it is 2.4. I think upgrading the version is not a choice for me because the server is controled by others, not our group. In addition, some zope concepts confused me. For example, our server actually hosts websites that are developed and maintained by different groups. And each group just manage its own folder. I think zope is better for this model. But when one group uses Zclass, they have to put their own zclass product in the control panel which needs administrative right. Is that weird? If i need to fix the bug in these zclass products, i have to have the right to access the root folder ( the whole zope ) so I can also change the contents belonging to other groups. Why do we put such constraints (zclass in contrl panel)? Why not create control panel for each folder and let each group has it s own private zclass product? Maybe I'm wrong.

A conditional dtml-in tag?
by RI Dunfey 17 Feb '04

17 Feb '04

Hi- I have a dtml page which displays the results of a sql query: <dtml-in expr="my_query(category1=category1, category2=category2)"> <TR><TD> <dtml-var NAME> </TR></TD> </dtml-in> The values that are passed to the query are obtained from the request object. If the value for category2=None then I want to leave category2 out of the sql query as below: <dtml-in expr="my_query(category1=category1)"> <TR><TD> <dtml-var NAME> </TR></TD> </dtml-in> The sql query has been designed to handle this using the optional tag. However, it falls over if I break the in tags up with an if tag, e.g.: <dtml-if "category2=None"> <dtml-in expr="my_query(category1=category1)"> <dtml-else> <dtml-in expr="my_query(category1=category1, category2=category2)"> </dtml-if> <TR><TD> <dtml-var NAME> </TR></TD> </dtml-in> I have also tried passing a string to the in tag, e.g.: <dtml-if "category2=None"> <dtml-var dummystr="my_query(category1=category1)"> <dtml-else> <dtml-var dummystr="my_query(category1=category1, category2=category2)"> </dtml-if> <dtml-in expr=<dtml-var dummystr>> <TR><TD> <dtml-var NAME> </TR></TD> </dtml-in> but the in tag cannot except a string? I have also tried handling this in python, as it is logic, however this too has been unsuccessful and would quite allow me to format the results as desired. I just want to control how the sql query is executed? Depending on the value of variables in the request object. Any help, much appreciated, Rob

popen2 problem with Zope 2.7.0 and Photo
by Troy Farrell 17 Feb '04

17 Feb '04

Greetings Zopistas. Since I've upgraded from 2.6.2 to 2.7.0, the following product code causes zope to hang: elif engine == 'ImageMagick': # Use ImageMagick if sys.platform == 'win32': from win32pipe import popen2 imgin, imgout = popen2('convert -quality %s -geometry %sx%s - -' % (quality, width, height), 'b') else: print "Started popen2\n" from popen2 import popen2 imgout, imgin = popen2('convert -quality %s -geometry %sx%s - -' % (quality, width, height)) print "Writing to stdin" imgin.write(origimg._IMdata()) print "Finished writing to stdin\n" imgin.close() newimg.write(imgout.read()) imgout.close() When I run zope in debug mode, I see "Started popen2" and the "Writing to stdin", but the process never gets to "Finished writing to stdin." Furthermore, zope will no longer respond to requests until I restart it. I already verified that origimg._IMdata() doesn't hang. I am using Photo 1.2.3 from http://zope.org/Members/rbickers/Photo/ with ImageMagick on Linux 2.2.20. Any hints? Thanks. Troy

Running Zope 2.7.0 / python 2.3.3 I ran into a bug with the File Library example app. When you click on the column headers twice to resort in reverse you get an error: Error Type: ValueError Error Value: An integer was expected in the value 'True' The url causing the problem is: .../FileLibrary/index_html?sort=date&reverse:int=True On Zope 2.6.3 / python 2.2.2 the example works and the URL is: .../FileLibrary/index_html?sort=date&reverse:int=1 Tom
