DateTime(), locale, summertime etc.
by Max M 09 Apr '05

09 Apr '05

I have a product where I convert some external datetimes to zope DateTime() objects. I save them as UTC as zopes DateTime does by default. But when these are rendered, the time is offset by two hours. A few weeks ago, it wasn't that bad. It was only one hour, but then summertime came along ;-) So it seems that there is some magic going on where Zope tries to take locale and summertime into account. Is this configurable somewhere. In Zope, Python, as a command switch or in a config file? -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science

newbie, setting member properties in python
by Dan E 09 Apr '05

09 Apr '05

I am trying to create a simple script that loops through the member properties and sets certain boolean ones to a certain value (which I have acquired). I realize I am probably making a simple mistake but the following snippet of code doesn't seem to set the member I am interested in. Any help would be appreciated. p_index =-1 for p in memberProperties: p_index = p_index+1 curr_value = cb_array[p_index] if p[0] == i #(checking for properties beginning with an i but could be any check) member.setProperties(p=curr_value); thanks in advance for any help, Dan

ExtFile Extention Mappings
by Edward Pollard 09 Apr '05

09 Apr '05

In our quest to replace the not-quite-working External File product, we're looking at ExtFile. However, when I upload files into an ExtFile, file extensions on the file system are being changed. test1.txt becomes test1.ksh, test2.doc becomes test2.dot. They have the correct ID's in the ZMI, but on the file system they now have something quite new. Our solution relies on accessing via the ZMI and the file system at the same time, so the name being changed is somewhat inconvenient in its unpredictability (and I think Apaches mime types will get nicely screwed if we start bypassing Zope to get at them). I've done some poking at the source code but don't see why ExtFile is doing this or what logic it uses. I bet someone out there knows. --- Edward J.

Persistent Objects
by Roy S. Rapoport 08 Apr '05

08 Apr '05

A coworker of mine wrote his own web server framework from scratch for an internal application. We're looking to migrate this application to Zope (thank God!). The only question we need to deal with is: The reason he wrote his own webserver rather than use CGIs is that there was some processing that needed to happen to initialize a system state -- basically, create an object that knows about the configuration of some things. In his model, this object is created at the beginning and is simply shared among the various Python objects/modules that are invoked when responding to user requests. How can I create such a persistent object that, say, a python script object or a page template could access? (Sure, handholding on this would be nice, but what I'm actually expecting is answers along the lines of "look into <foo>") -roy

symbols undefined after product refresh?
by Jürgen Herrmann 08 Apr '05

08 Apr '05

hi! after reloading my own products through the zmi it seems like some classes and methods gets undefined. please see the following traceback: ... Module Python expression "here.zuml_parseAndCheckinModel(newConfigDict)", line 1, in <expression> Module Products.IDE.IDEContainer, line 176, in zuml_parseAndCheckinModel Module Products.Relateable.MetaManager, line 474, in recreateIndexes Module None, line 104, in addSubClassCatalogMethod TypeError: 'NoneType' object is not callable the code @ line 104 is: o = SubClassCatalog(id, searchKeys, subClassNames) SubClassCatalog is defined in /Products/SubClassCatalog/SubClassCatalog.py, after I refresh the Product "SubCLassCatalog", i get the error mentioned above. restarting Zope fixes the Problem, MetaManager::recreatedIndexes() will work repeatedly until i refresh one or more Products... did i miss something while importing stuff? /Products/relateable/MetaManager.py imports the constructor for a SubClassCatalog like this: from Products.SubClassCatalog.SubClassCatalog import addSubClassCatalogMethod i'm pretty puzzled at this point, hope someone got a hint... regards, juergen herrmann ps: this does not only happen to my SubClassCatalog, this also hits f.ex. "from random import randint" where randint gets undefined.

best practices Zope filesystem development
by Milos Prudek 08 Apr '05

08 Apr '05

Hi, What are the best, most effective practices in leveraging filesystem when developing in Zope? I'm looking for an approach that would let me use keyboard and leave the mouse alone as much as possible. In other words, minimum use of ZMI even if TTW Python Scripts are used extensively. Instead of ZMI/External editor I need vim, grep, mv and cp to manipulate Zope ZODB. -- Milos Prudek

Zope/python: downloading images from the web and add them to Zope
by BonviciniJ＠keops.net 08 Apr '05

08 Apr '05

I would like to know how to add image file from an URL. I created a form with to pissibilities: add an image from a local file , and a image from an url here is my form: <input type="radio" name="sourcePicture" checked onClick="lock_option()" value="file"> get from disk: <input type="file" name="pict_file" size="40" accept="image" maxlength=500000> <br> <input type="radio" name="sourcePicture" onClick="lock_option()" value="internet"> get from the internet<input type=text name="pict_internet" size="40" value="http://www.monsite.fr/monimage.jpg" disabled="disabled"> This form call a python script: if REQUEST.sourcePict=="file": pathImgs.manage_addProduct['OFSP'].manage_addImage("pict_"+id, REQUEST.pict_file, title="pictogramme metier", precondition="", content_type="") else: pathImgs.manage_addProduct['OFSP'].manage_addImage("pict_"+id, REQUEST.pict_internet, title="pictogramme metier", precondition="", content_type="") With a locl file it works (case sourcePict=file), but when I want to add images from an url, it doesn't work. I suppose that the second parameter of manage_addImage must be a file type.In the first case, it works , but in the second, the parameter passed is a string (complete url of the image). so how to do? thanks for your answers and excuse me for the lack in English (I'm french)
