Actually, if you look at the code, i *think* I have stuff in there to allow you to use it with a RAMCache. The idea being, make a RAM cache for caching all thumbnail images, not just private caching for each instance. I'm still unfamiliar with how that all works in Zope, but architecturally I think that's the best place to put a cache (external to the images themselves). I still don't see how to get this caching to work for all instances, it seems the caches need to add one instance at a time... But this way, they are stored where appropriate (cached), but not stored inside the image (which could lead to unneccessary data.fs bloat). > I am not to swift with python yet so I just went in and duplicated the thumb > method and made some methods called "preview", "small", and "medium"giving > them > default sizes of 160X120, 320X 240, and 640X480. The way I have it working, if you call tag() with the same size twice, at the least, the client browser should use the locally cached version (at least, it did for me), so I don't see that it's necessary to have specially named methods. For example, in my CMFPhoto and in the original ZPhoto, the thumbnail pages always call tag with a size of 80, so they'll be cached (at least per client) the second time around. >I have this working now but I > noticed one little bug in your code.

I guess that gives me a reason for version 0.2 (along with changing the name to image HotPatch!) -- though I'm hoping to figure out the RAMCache situation (help! somebody!) first... > > Now I have one question, if you don't mind.

If you have time to take a look at this I would really appreciate it. I have thumb hard coded (in tag), because that's the method the browser will then call (with arguments) to actually fetch the image. I guess, if you're rolling with the three special method approach (though I don't think it's necessary), then in tag I guess you'd either create a new parameter for tag (size=[preview,small,medium]) or match one of the three names with a range of sizes, and put more if/elses in there to return the right one. > > Thanks for the great work! > > Phil. > > Philip Aylesworth > phila(a)purpleduck.com

Bug in PostGre adapter for Zope, for type string in arguments of ZSQL Methods (?)
by acg 23 Aug '01

23 Aug '01

(ok, sorry, i´m spanish.. ;-D) I´m trying to do something like this in a ZSQLMethod: select * from table_name where table_field1=<dtml-sqlvar argument1 type=int>; And it works successfully. But if I try with: select * from table_name where table_field2=<dtml-sqlvar argument2 type=string>; I get an unexpected error: Error, exceptions.NameError: global name 'string' is not defined -------------------------------------------------------------------------------- SQL used: Could not render the query template! I have tried some another ways to access the query: select * from table_name where table_field2='<dtml-sqlvar argument2 type=string>'; select * from table_name where table_field2=<dtml-sqlvar argument2 type="string">; select * from table_name where table_field2='<dtml-sqlvar argument2 type="string">'; ... But, nothing. If i try this: select * from table_name where table_field2='value'; It works successfully again. Why can´t Zope render the query template? Why does Zope say "globla name string is not defined"? I´m using... Zope 2.4.0 Python 2.1.1 Linux ZPoPyDa (Last Version? I´m not sure of this) I need the Help. Every comments can help me. Thanks.

RE: [Zope] ZCatalogAware: changing catalog name
by Rob Foster 23 Aug '01

I just recently ran into the same issue... You can create a Python script in the methods directory of your zclass that sets the default catalog to a different ID... Example: # Example code: # Edit the property sheet and reindex. context.manage_editCataloger('TheNameOfYourCatalog') Hope this helps.

It works as expected, if the ZCatalog has the Id 'Catalog', but doesn't work if I give it an other id (e.q. TestCatalog). Where do can I change the id used for the ZCatalog in my Product/ZClass?

uncatchable 'Bad Request' exceptions ?
by Florent Guillaume 23 Aug '01

23 Aug '01

Zope 2.3.3, python 1.5.2. >From a python script I can't seem to catch a 'Bad Request' exception. This doesn't work: # script1 raise 'Bad Request', 'foo' # script2 try: context.script1() except 'Bad Request', x: return x return 'nothing' I get a Zope error: Error Type: Bad Request Error Value: foo But the following one works... # script1 raise 'bar', 'foo' # script2 try: context.script1() except 'bar', x: return x return 'nothing' And this one too... # script1 raise 'Bad Request', 'foo' # script2 try: context.script1() except: return 'something' return 'nothing' Anyone has an idea ? The exception is raised by another product which I don't want to touch (CMF RegistrationTool), and I think I should be able to catch them ! Florent Guillaume Nuxeo

Invalide syntax on (of all things) def initialize(context):
by complaw＠hal-pc.org 23 Aug '01

23 Aug '01

As impossible as it seems, my Zope 2-3-1 had the temerity to say this __init__.py.... import Doctrine def initialize(context): """Initialize the Legal Doctrine Product.""" context.registerClass( Doctrine.Doctrine, constructors = ( Doctrine.manage_addDoctrineForm, Doctrine.manage_addDoctrine ), icon = 'images/Doctrine.jpg' ) .. gave me this... Import Traceback Traceback (innermost last): File "/usr/local/zope/2-3-1/lib/python/OFS/Application.py", line 536, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/zope/2-3-1/lib/python/Products/LegalDoctrine/__init__.py", line 3 def initialize(context): ^ SyntaxError: invalid syntax I've seen def initialize(context): done for several different Zope products. Does my instance of Zope just not like me? Someone please tell me that I'm not crazy. Ron
