> Hello, > > A newbie question. Could you pls propvide an example of mentioned > in readme.txt "preview" and "icon-gif" methods to view thumbnails and > images? > > Best regards, > Alexander N. Chelnokov Hi! Create an ExtImage object (e.g. in the folder path/to/your) and upload an image (e.g. image.jpg). You can now call the image with: http://your.server:8080/path/to/your/image.jpg or http://your.server:8080/path/to/your/image.jpg/index_html the preview is accessed via http://your.server:8080/path/to/your/image.jpg/preview and the icon via http://your.server:8080/path/to/your/image.jpg/icon_gif hope that helps, MacGregor!

Objet : [Zope] How to test if an object exist
by Francois-Regis CHALAOUX 24 Aug '00

24 Aug '00

Hi, Thanks for the details on hasattr function. I learned a lot ;) In the meantime, I found an other solution. Have a look. Bye, FR. Here I create folders in the folder "self.folder1". Each new folder has a number at its end (folder11, folder12, etc ...). def testFolder(self): self=self.this() sub1=self.folder1 l = ['1','2','3','4'] for i in l: sub2= "self.folder1" + ".folder1" + i folder = "folder1" + i try: if eval(sub2): pass except AttributeError: sub1.manage_addFolder(folder) return 'ok'

Product release: ExtFile/ExtImage 0.91
by Heine, Gregor 24 Aug '00

24 Aug '00

Version 0.91 of the ExtFile/ExtImage Software Product has just been released. The ExtFile and ExtImage Products store large files in an external file-repository and are able to display icons for different MIME-Types. The ExtImage Product additionally creates preview-thumbnails from images and displays them. ExtFile and ExtImage basically work like the Zope File and Image products but the (binary) file is not stored inside the ZODB, but in an external file-repository. Only meta data (like title and description) are stored in the ZODB. This prevents the Database swelling up quickly, when many large files are uploaded and thus increasing database performance. Version 0.91 fixes an important security issue, that allowed read access to any file in the local filesystem (readeable for the UID of the zope process). The Product is avaliable at http://www.zope.org/Members/MacGregor/ExtFile/ MacGregor!

NTUserFolder Object. Where is it?
by Christian Adams 24 Aug '00

24 Aug '00

I have, apparently, sucessfully installed NTUserFolder into my Zope installation. Now I need to add some NTUserFolder objects to some working directories. My rather silly problem is this: Where do I have to look for the NTUserFolder object? It's not in my usual Objects drop down menu so what have I forgotten to do? Zope 2.2.0 over NT4 NTUserFolder 1.3 Chris. > Chris Adams > Revolution - the new commerce agency > -- > Direct: +44 20 7549 5837 > Facsimile: +44 20 7549 5801 > http://www.revolutionltd.com > >

Re: Can't compare apples to apples. (document_id != id_of_my_document)

Am I missing > something? I've tried _.str(document_id) and even > _.string.strip(_.str(document_id)). The tag <dtml-var document_id> gets a value for document_id, and looks to see if it is callable. If so, it calls it and returns the result of calling it. If not, it just returns it. This is a feature of <dtml-var name="whatever">, which is another way of writing <dtml-var whatever>. However, when you use an expression, such as you are doing in the dtml-if tag, you are writing in Python, and you need to call an object if it ought to be called. An expression is something like <dtml-var "expression"> or <dtml-var expr="expression>, which are equivalent. The same goes for <dtml-if "expression">. In your case, you might find that this works: <dtml-if "document_id() == 'apples'"> Or perhaps this: <dtml-if "document_id(_.None, _) == 'apples'"> The reason is that ids ought always to be simple string objects, but some aren't. There are lots of legacy programs that rely on some ids being methods, so the odd cases won't be changed for a while yet. The general answer is to use a special function that calls the value if it is callable. You have a choice here. These are equivalent. <dtml-if "_['document_id'] == 'apples'"> <dtml-if "_.getitem('document_id', 1) == 'apples'"> -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

The tree tag, SQL and what should be simple
by icottee＠bluefountain.com 24 Aug '00

24 Aug '00

I thought this was going to be simple but having read numerous postings on the mailing list and all related HOW-TOs I can find, I think I can confirm I am stuck. This is sad because I've just spent a very productive couple of days with Zope and MySQL making the world a better place. I have a table for chickens. Basically it looks like this CREATE TABLE T_CHICKEN ( ID INT NOT NULL PRIMARY KEY AUTO_INCREMENT, CODE CHAR(10) NOT NULL, DESCRIPTION CHAR(40) NOT NULL, NOOFLEGS INT NOT NULL DEFAULT 2, TYPEID INT NOT NULL ); And another table for types. CREATE TABLE T_TYPE ( ID INT NOT NULL PRIMARY KEY AUTO_INCREMENT, CODE CAR(10) ); Each chicken has a type associated with it. At the end of the day I want to display the chickens underneath the type it has ... start the screen up it would say + BIG + MEDIUM + SMALL And the users can then expand to see the chickens available in each category. + BIG - Flossie - Wombat - Hank + MEDIUM - Debbie - Fruitbat - Harold + SMALL - Bob It would appear that I need to feed two things to the dtml-tree tag. Firstly my starting levels (my types) and then the related data underneath but I can only feed one SQL query to the tag. All the stuff I read seems to assume the info at the top level comes from the same file (and from a key id). How do I do this or indeed, is it possible? I have a nasty feeling I am missing something obvious. Ian
