Hm, I'm afraid this is a DTML trick (nothing more). I hope I can explain this right. Please correct me if I go wrong. Normally in DTML, you access variables in the current namespace with , which actually stands for In an expression like the one used by J you actually use an expression, like , in which case you do not get the id variable in the current namespace, but the actual value of the id attribute (property) of the object in the current namespace. The problem here is that the id of index_html is a python method (which is actually returned by ). This will never be equal to 'index_html' as that is a string. The solution is to call the variable in the current object namespace by using it like a dictionary in the python expression . Because it's a method, you could (in this case) also use , in which case a string is returned (so that will once again be useful. However, the _['id'] is preferred, because it will work on different objects and the id of most other objects is a string. For example: do something nice would work, whereas would break if there are objects whose ids are not methods (assuming File is one of them, which I wouldn't know) So the different forms are (actually there are some more, but they do not matter here): will give you an error Now that was probably more English than you'd hoped for hth Rik ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Perhaps, but i think this is not necessary (though I liked the product
idea). Should you become a member of the ZDP site, than Maik already created
many such tools, including commenting, reviewing, discussing etcetera (and
search possibilities for documentation that needs it). We badly need people
for these tasks, though, and nobody has taken these tasks up yet. Mindlace
just yet announced serious involvement by DC, but we never had input from
them before (sorry to say so)
Please take into account that at the moment the whole ZDP, including
programming, writing documentation etc, takes the effort of far less than
ten people, who work at it in their spare time. Or to put it differently:
ZDP NEEDS CONTRIBUTORS, REVIEWERS, EDITORS, WRITERS
Help us out and the whole Zope community will benefit.

This has a negative effect on the performance of your application as it adds to the overhead (putting another layer between your webserver and your image retrieval). I don't see what the gains would be. If you consider putting image descriptions in your database, do so and no more. Put the images on a filesystem somewhere and make your database records point to them. This is much easier and much faster. If the number of images is large you may have to do some thinking about the directory structure. hth Rik ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

If from the management interface, are you sure you always add TinyTable etc from within the instance? If programmatically, could you send the code? Perhaps you could try and adding one of the problem products in another way (from a dtml method instead of the management interface or the other way around).

Re: [Zope] PropertyIds
Thanks Rik it works. I've noticed in some cases that one puts empty brackets at the end of certain zope object methods. Is that there for methods that can take parameters? [rh]Um, not quite, it has to do with the way of calling the object methods in question. DTML has two ways of calling: by name and through expressions. 1. The 'normal' Zope way of writing things is . This is shorthand for . 2. The other way is . This is shorthand for . Everything inside the expression is treated as a python expression. If you call it without the brackets, you're just referencing the method. If you try that in a DTML Method and look in the source of the diplayed document you'll see something like . If you want to _call_ the method, you'll have to add the brackets (with or without arguments). Hope this is clear.

Why this is a problem, I can't tell, but this _is_ the problem. I'm not quite sure about the solution. Probably it's best to make a custom manage_main form that does the right incantations for adding products and then map this to your Contents View in the ZCLass definition. As a side I'd like to remark that all products should comply with the same manage_addProduct interface, because the current situation leads to nasty problems.

Not sure if this was the question, but here's a relevant quote from the
python library reference
Return a new file object (described earlier under Built-in Types). The first
two arguments are the same as for stdio's fopen(): filename is the file name
to be opened, mode indicates how the file is to be opened: 'r' for reading,
'w' for writing (truncating an existing file), and 'a' opens it for
appending (which on some Unix systems means that all writes append to the
end of the file, regardless of the current seek position).
Modes 'r+', 'w+' and 'a+' open the file for updating (note that 'w+'
truncates the file). Append 'b' to the mode to open the file in binary mode,
on systems that differentiate between binary and text files (else it is
ignored). If the file cannot be opened, IOError is raised.

Yes this can be complicated, but most real complications are caused by acquisition, which is one of the main Zope features. What is a pain, is the way of handling namespaces in DTML.

By slicing:
gets you the first element parsed_string[1] the second etc
parsed_string[1:] is everything after the second ;-) element of the list
parsed_string[:5] is everything up to element 6
parsed_string[1:5] is everything from element 2 to element 6
parsed_string[-1] is the last element of the list.
If you want to know more, you should probably look at the Python docs, as
this is Python stuff.

Um, perhaps a stupid question, but can it use other ports for ftp and/or can you reach the server? If so, you can easily change the ftp port in the z2.py program in your zoperoot (it's heavily annotated, so that shouldn't be a problem).

The error means you're trying to split up a string, but the argument is
no string, but an instance (a Python Object). In many cases this is
caused by an omission of parenthesis, like so
called_object instead of called_object()
in which case the object is referenced instead of called and nothing is
returned (of course). I did not find the culprit in your description,
though.

I do not quite get what part you want to parse. Is it 'SB_B208'?
accessing this in python is a bit strange due to the returned value. You
get to the 'SB_B208'part in the following way:
whateverreturnstheresult()[0][0][0], meaning (in this
case):
the first element (of the list) of the first element (of the first

Re: [Zope] get 2 properties at the same time
Hello, I need get 2 properties of Zclass at the same time. [rh]Unless I understand your question wrongly, this is going to be more easy then you think (sidenote that this dtml-in is iterating the objects in Locality, not the properties) I need get another property, for example MASTER_REGION, in this moment. [rh]Just call it (doesn't matter whether it's an object or a property - as defined in a ZCLass Propertysheet) If you want to do the same thing as with the Locality objects, just repeat your code here.

Um, perhaps a stupid question, but since you are talking about files - is this a Zope object that is in the Zope object database or is it a file that is on your file system?

Re: [Zope] Problems and ponderings
In my site I have folder with subfolders and I would like to generate a menu to go to those subfolders. What I have now is: which gives emptynes.. I've tried all kinds of combinations, tricks from the tips and howto's, but nothing. [rh]First, why do you use sequence-key? Use sequence-item instead second Actually I start thinking that zope is not for me. Yes, I'm a programmer, but here and now creating websites. I want to create a website, not publish objects. An abstactionlayer between zope and python would be a good thing. (and don't tell me DTML IS an abstractionlayer. It confuses the matter, it doesn't simplify. Including perl straight into the pages would be simpler. Not to mention that Python is actually decently documented..) [rh]No one will tell you DTML is ideal,. It's meant to be a presentation language and for that it's powerful. If you want to write python inside Zope - use PythonMethods. If you really want to put perl into your webpages - there is PerlMethods coming up, that presumably can do the same as PythonMethods. Anyhow, I'm not giving up yet let's check my mental image: A zope site is an tree of objects, objects inherrit from parents. [rh]Yes, and they acquire from parents. Acquisition is a type of dynamic inheritance (how do I check if a parent exists?) so there should be a way to refere to the parent (PARENTS[]) to refer to the current object (?). [rh]current object is this() for most purposes. I do not quite get what you're aiming at. But the current object depends on the namespace and the namespace is a stack determined by parents, using acquisition. Traversing the namespace changing the current object, and so do dtml tags like dtml-in and dtml-with. The best introduction to these is probably in http://www.zope.org/Documentation/How-To/AdvancedDTML I guess there should also be a way to refer to objects in an other branch of the tree (I would like to have a tools folder which is also searched when asking for a DTML-methode) [rh]This can be accomplished (simply) by using ."> your code or more directly .()"> But there are many other methods of doing this in more sophisticated ways, depending on your needs Is my mental image to limited?

this seems to be a filesystem problem rather than a Zope one- what OS are
you on? Are the permissions for the directory set right (Zope runs as nobody
on Unix I think)
One more small suggestion - the last line of your method has a typo
>temfile.close()
I might want to change it to
>tempfile.close()

Perhaps no one knows the answer to what seems to be a rather specific situation. For one, I have the impression most people use zodbc connections to access database then use the zjetadapter (so do I, so chances are I might be just blabbering). > I am having a permissions difficultie with ZJetDA trying to > modify data in an Access97 database.

If so, then the security thing should be the same on both, right? If not - then how can you say all objects are the same?

Re: [Zope] Lock and Transaction in Zope.
Zope has no built in locking like that, but IIRC there was some hack in the wiki code to prevent simultaneous editing (which wasn't bullet proof). Perhaps you can look there. I doubt whether it will solve the problem you pose, but I don't see why you'd want to do what you pointed out in your mail anyway.

MYZClass contains an image object...how do I change the and > edit the photo contained in the class > I don't know if I get this right. The point of ZClasses is that they provide common behaviour for all instances of the class. This means that if you have an image in the ZClass, it will be available in all the instances, but if you change it 1) that can only be done in the ZClass definition and 2) this will affect all your instances. If you want an image that is specific for your ZClass instance, you'll have to put it into the instance. You can change it there like any normal Zope object. Creating the Image object inside your instance can be done at the time the ZClass is created and you can also customize the image object at that time. Please provide more details as to what you try to attain if I got your question wrong. hth Rik ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

You can just about anything you want using external methods (written in Python) or Python Products, including reading, writing, deleting and changing and using regular expressions.
