Re: [Zope] LocalFS on Win2k
Hi, I had the same error with LocalFS on a NT 4.0 server. In my case it was a security problem. Zope wasn't allowed to access the directory I used. Now I placed my local files in a directory Zope is allowed to read and everything is working fine.

Re: [Zope] How to see if two objects are the same (minor fix)

When you look up an attribute of this object, it will first in the object itself and when it does not success there, it will look in the context. That is what you like with acquisition. The downside: When you access the "same" object via different contexts, you will in fact get different objects (as the contexts are different). "is" will return false, as it should be. But, even, if you use "==", you will get "false". There have been some discussion in the list, whether this is the best behaviour. What can you do? You can use the "aq_base" attribute to strip away any context and get to the base object. At least in Zope 2.2.1, "aq_base" was not exposed to DTML. Thus, you would need an external method, say "getBaseObject", to get at the base: def getBaseObject(object): return getattr(object,'aq_base',object) With this function, you can compare the base objects: dtml-var "getBaseObject(myvar) is getBaseObject(PARENT[-1].myvar)" Be careful, however: Even, if such a test returns true for two objects, the objects may nevertheless have different behaviour (as the contexts are different).

"Manuel Amador (Rudd-O)" schrieb: dtml-with pub dtml-let titel="_.string.join(['This is the website of ', enterpriseName])" dtml-var standard_html_header /dtml-let on your document, WILL work fine. But I suggest recreating standard_html_header as a METHOD and calling OK, once again: My standard_html_header is still a METHOD!!! And within it, I DO access to the variables of the calling document / method! dtml-with pub dtml-var standard.. /dtml-with That's _exactly_ what I did! I only inserted a dtml-let someVar="someValue" to pass this var to standard_html_header. Since methods don't have properties, they will use calling object's properties. Read again. Do NOT use DTML documents for headers and footers. Use METHODS. I DON'T! So I stored my headers and footers and many other things in root/intra/pub. All the other documents are stored in root/intra and below. I've got my standard_html_header, with which I can display user-defined titles which may also contain values of global properties. The user-defined title is being built in the document before the header is called, e. g. something like: Look above! In the standard_html_header !!!_method_!!! I'm checking whether there is a titel attribute or not. This works fine. But for general use I want to keep the possibility of displaying the title_or_id of the document when I don't introduce a user-defined title. This would be no problem if s_h_h wasn't situated in root/intra/pub, so I have to call it within the dtml-with pub. But calling it within the dtml-with pub, pub is on the top of my namespace, so that calling title_or_id returns the title_or_id of the container of s_h_h, i. e. pub, INSERTED: and not as wanted the title_or_id of the calling document! How can I nevertheless access within the s_h_h to the title_or_id of my original document? INSERTED: i. e. explicitely accessing to a layer of the namespace which isn't on its top!

[Zope] Content Management System

I've been struggling to make the CMS abilities of zope user-friendly enough for 'joe average' end-users. Really it's designed for a 'power' content manager who delegates, secures, and generally has taken the time to study all the Content Management docs, etc. However, most of my clients don't have those kinds of requirements and aren't that technologically savvy, so I end up coding ultra-simplified interfaces for them on a per-project basis. I know you can restrict permissions on just about every available method, and I am aware of the current skinnable zope project, which may improve the situation drastically. But I'm interested to know, how many of you offer the Zope TTW interface to clients as a content management system, and how many just use it as a development interface? I'm beginning to wonder if content management and system administration should be split out into separate subsystems. Or if a CMS Tool Kit should be developed. (workflows, syndication, etc...).

RE: [Zope] Access Control vs Publishing Protoco
oops, I forgot to foward my last mail on this subject to the list. My response here to Dieter's response captures contains the main points though... I think, the implementation would be easy. Management, however, would be more difficult, as there are no good defaults for the "URL Traversable" permission. It is not easy, to determine (e.g.) for a DTML method/document whether it is only used as a component (such as "standard_html_header") or is a full grown presentation method. Um, I don't think I understand. [ snip ] Currently, Zope tries to have very few explicit, object specific permissions. The ideal is that permissions are specified high above in the hierarchy and acquired by lower objects. This is quite possible with the current scheme. Implementing an "URL accessible" permission would require much more tweaking of single object permissions. There are other ways to solve your problem by organization (putting things that should not be seen somewhere else) that do not require an additional permission. Now I understand... I would disagree, however: I think there is a sensible default value. The default would be that anonymous does not have 'traverable' permission, but the manager / owner does. The cases where an authenticated user is able to traverse some objects but not others would, as you point out, be rare, because you could instead manage these by organisation. You would still use organisation to avoid having to set too many additional permissions. However, this solution would solve the 'security' issue of the anonymous user being able to list objectIds in any folder TTW. It would also allow the developer more flexibilty in how they designed their application, which can only be a Good Thing? seb. ___ 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 )

Zope as a CMS _is_ possible, but IMO you'll have to wrap the parts of the management interface that you want to expose to your users and hide the rest. This will effectively limit you as to what you will let your users add to Zope, but in a CMS situation, this will probably be the case anyway. The management interface as is won't mean much to most of them, but custom forms can also call the manage methods. It's probably a good idea to use something like the HTML Widgets product that was recently announced here, or the HiperDom thing. For most of the user management parts you will probably need someone with affinity for web developing, though as long as you keep the tasks constrained, some simple instructions will probably suffice. I have been developing something similar in what should be a course framework (a product that I don't seem to be able able to finish) that is geared toward an educational situation.

For example, take a .gif or .jpeg file and throw away all

If you try to open this truncated file with an image editor

information is still stored in that first part of the file,
as we can see using python and PIL.
Example, on linux:
head --bytes 1000 foo.gif foo_truncated.gif
python
...
import Image
test = Image.open('foo_truncated.gif', 'r')
test.size
(210, 210)
So in this case, we can find out that foo.gif is 210 x 210
pixels even if we only have access to the first 1 kb of the
12 kb file.
This doesn't hold true for JPEG's.
A JPEG encoded image consists of a set of segments, each encoding some
aspect of the image. The image dimensions can be found in the frame header
segment, but this segment may be preceded by tables, comments and
application specific data.
These extra segments could easily take up your 1K chunk. AP press for
example, uses an application specific segment to encode image metadata
such as subject, caption and photographer.
If you have a look at the Image dimension detection code for JPEGs you'll
see that it scans for a frame header (marked by C0, C1, C2 or C3 depending
on the encoding used). Once found, it extracts the width and height. More
information of the JPEG file encoding format can be found at:
http://www.w3.org/Graphics/JPEG/itu-t81.pdf
For a GIF file, the first 10 bytes should suffice, for a PNG you need the
first 24.

In test of the submit button, the dtml-sql method called is structured: dtml-in item update table set field2=dtml-sqlvar field2 type=nb where field1=dtml-sqlvar field1 type=nb dtml-sql_delimiter; /dtml-in and the conditions of the method are item:records. The intention is to submit in one go the entire list of occurences and update anything that has changed. You can do this with checkboxes valued on the primary key and other ways. The important thing is to leave something that you use as the key in the WHERE statement. Okay, this works fine, in MOST of my forms, but I have other forms where this doesnt work at all and I get errors saying that the ITEM is a bad request. I dont get it, what am I missing here that this works some places and in other places with almost identical syntax, it falls over. The form is correctly tagged, does the name attrib of the form tag have to do with the dtml-in item... doesnt seem to be but tried it. Im wondering if because the dtml-document is quite large with seperate subloops and forms that publish in a sequence of events that this doesnt work. Hopefully someone has insight I'm missing here?

[Zope] Competing writes and reindexing objects
Zopists, I am trying to eliminate the competing writes that are plaguing my app at the moment. One way I know of is to make sure that people aren't creating/modifying objects in the same folder at the same time. This is becuase the parent object gets modified too. Does anyone have a "object creation/folder distribution" code that works for them that they would be willing to share? Lastly, even if I distribute my objects, doesn't reindexing any Zope object inthe Catalog at the same time create a conlict? I'd love to know if I'm fighting a losing battle here.

Me again, To further explain my dilemna, I just noticed that using the in ITEM loop doesnt seem to work if the dtml-call statement has an extra parameter.

Re: [Zope] Medusa Monitor
Thanks for the follow-ups on Medusa Monitor. But as I can see (after using Zope for 1.5 years, now), few people actually use it. Unless one is really into the guts of Zope itself, the monitor is pretty useless for debugging. It of course could be made more useful, but one must implement some Python programs first. Even for dynamic reloading of modules, I usually just write External methods to do the job, instead of firing up the monitor. A more useful debuging tool would be some monitor where you can receive print message logs in real time. That would be great, especially if you have multiple thread problems. regards, Hung Jung _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

[Zope] dtml-sqltest and capital column names
Hi,
I'm using zope 2.2.2 with postgres 7.0.2 and ZPopyDA 0.6.4.
I encountered a problem with dtml-sqltest and capitals in column names.
Well, I simply couldn't get it to work because postgres requires
column-names with "special characters" like capitals to be enclosed
with quotation marks, ie. "COLUMNNAME" instead of COLUMNNAME -
IIRC '_' also won't work.
The problem is that dtml-sqltest only renders
select * from table where COLUMNNAME='5'
which will be interpreted by postgres like
select * from table where columnname='5'
Unfortunatly dtml-sqltest bla column="BLA" type=int throws the
obvious error and everything else I tried didn't work too.
In the end I patched lib/python/Shared/DC/ZRDB/sqltest.py
to do what I want.
165,166c165,166
if has_key('column'): self.column=args['column']
else: self.column=self.__name__
---
if has_key('column'): self.column='"'+args['column']+'"'
else: self.column='"'+self.__name__+'"'
Any comment whether this would also apply/be necessary for other dbs?
And if not, would there a better place (anywhere in ZPopyDA)
to change/add some code?
Or did I just miss something obvious and there's a sane way
to make dtml-sqltest work with postgres and capitals.
cheers,
oliver

The lack of a security context means, that the default security setting built into the Zope security policy is used. In Zope 2.2.2., this means, only "Manager" can do anything, unless the object itself mapped some permissions itself to roles (which then remain valid even for the base object). However, I see another danger. As old (now fixed) bugs in "ZopeFind" have demonstrated, objects stripped of their acquisition context lead to very strange errors, where suddenly even Manager cannot use the object any more.

Case in point: I want to put a table of dates and hyperlinks. If the day has already passed, I want to shade the table cell (td bgcolor="gray"). In this case, the object has a date property called event_date. table tr dtml-if expr="event_date DateTime()" td bgcolor="gray" dtml-else td bgcolor="white" /dtml-if /td /table The above code gives me a NameError. Another example would be to simply get the integer value of the year so that it can be included in a copyright statement. E.g., Copyright copy; dtml-var Year(), All rights reserved. Unfortunately, this doesn't work either.

Re: [Zope] Medusa Monitor
I know that, the stupid log file thingy. But you'll have to write an independent thread to display the log file (or peek the file manually each time), or implement some CString stuff to capture the file output (if that is possible). It'll be more fun if all this is already done, and the user can just tap into the monitor console screen (even remotely). A good monitor should actually display hit information, memory usage, etc, and preferably with charts, all in real time. Too much to ask?

Re: [Zope] Content Management System
I'm beginning to wonder if content management and system administration should be split out into separate subsystems. Or if a CMS Tool Kit should be developed. (workflows, syndication, etc...). We (iuveno) are currently preparing a major project to write a full-featured CMS on base of Zope. The first client will be a university, but the system will also be usable in commercial environments, and it will be open source from the first day on (except for the client-specific stuff of course). The first draft of the general architecture is as follows: There is a ZClass- or Python-product-based toolkit that provides the standard functionality, like base classes, workflow logic, etc. Plugin ZClasses implement the actual organization logic, so you can choose between building a university, a sports club, or maybe a consulting business by just choosing the corresponding modules. Chromes (logos, stylesheets, ...) and Views (page layouts) are also implemented as plugins. There will be a full-fledged workflow/project management component (at least in the long run). The concept will build upon ideas from the PTK and the ZDP-tools. There is a very simple prototype we will make public after some clean-ups. We are checking at the moment if we should set up a now project homepage or wiki or join an existing effort like the ZDP-tool-based initiative of Maik Röder on or the PTK. BTW: My experience with "dumb users" working with the Zope interface is quite positive. As long as they just have to add, change or delete predefined objects it doesn't seem to be that bad. They just shouldn't have to know about DTML or even acquisition.

Re: [Zope] Connection Problem with Oracle
I created a connection to an Oracle database. Frequently, the connection breaks and I got a database error in the page that displays the query result. When I logon as a manager I find that the connection is closed (by itself, nothing changed in Oracle or Zope), when I try to open it I get an error "Invalid connection string". Even if I create another connection it can't work.. After a while it works. Even after restarting the Zope server the problem persists. I'm not sure why the same connection string would work only some of the time. Maybe some other error from sqlnet is misreported. In any case, look for sqlnet.log at the directory where zope was started. You can get more info on the errors you're experiencing. Furthermore try running zope with nohup and monitor the nohup.out file that gets generated. You can see how frequently your zope goes down (if running as deamon under linux). Frequent problems with Oracle setup stem from read permissions on files used by sqlnet (e.g. message files). Make sure such files are readable by whatever user your zope is running as.

Re: [Zope-dev] Xron fragility
What if you want a small job to be done every 30 seconds? I generally don't... I'm satisfied with cron granularity, although others might not be. Do you have this requirement? I thought a little about the granularity issue and decided to go with the most general solution. I have no requirement for 30-second intervals, but I wanted to avoid support requests from those who might have such a need. Also, I have no need for large numbers of scheduled methods. But I used a heavy-duty data structure (Catalog) and the sleeping dispatcher model, just so there would be no arbitrary limits that would cause me support headaches later. It uses Client.py to run a job. Why is this? This doesn't make any sense to me on its face. Why not just call the method from a separate thread? Which separate thread? Do you create a new ZODB thread? That sounds as if it might use quite a few resources. Is there a Zope API for making ZODB threads call methods on objects, as signalled by other threads? I'm guessing the easiest way to do that is to use Client.py to make a new http request. Yes, using Client.py was the easiest way to do that. The biggest problem with Client.py is its dependency on HTTP. If your server is set up to only accept HTTPS, then you can't use Xron -- not a desirable trade-off. We need another mechanism that achieves the same goal -- simulating the environment of a request -- without going all the way back to the socket. -- Loren ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] A couple of ZPatterns questions
At 06:15 PM 10/12/00 +1100, Itai Tavor wrote: Hi, 1. I want to set some object attributes every time the object is changed (for example, to store the name of the user making the change). I looked at using a Generic Trigger or a SkinScript but I can't figure how to do it with either one. With a Trigger, I guess I need to set "Set Sttrs" to all the object attributes except the ones I intend to set (otherwise, would setting an attribute in the Trigger cause the Trigger to be called again?) and then call a method to set the attributes - but how do I set the attributes? Do I have to call changeProperties for the object or can I make the change directly on the DataSkin? You can only change the attributes directly by calling an External Method, so changeProperties would be the more direct way. You are correct that you must list the attributes *other* than the ones you want to change, otherwise you will cause an infinite recursion. In some older versions of ZPatterns, you may get the recursion anyway. :( With SkinScript, I can't figure out the STORE and USING syntax... also, if I use WHEN OBJECT CHANGED to change the object, would I get infinite recursion? Can I evaluate REQUEST['AUTHENTICATED_USER'] in the SkinScript or do I need to call a method for that? Yes, you can say REQUEST.AUTHENTICATED_USER. No special methods needed. To write SkinScript equivalent to a generic trigger, the form is: WHEN OBJECT events STORE set attrs USING expression SAVING stufftosave This performs the same as a generic trigger with the same parameters. 2. I want to store a list of products, and give each one an arbitrary number of photos. I can use a Product ZClass, subclassed from ObjectManager and store Image objects inside it. But what will happen to these objects if I use this ZClass in a Rack? And how would I handle storing the objects in SQL tables - I will need to somehow turn each Image object into a table entry, and the same Generic Attribute Provider will have to work with 2 SQL tables. Is there a nice way of doing this? Or should I store the photos in a separate ZClass and use it in another Rack in the Products Specialist? I would not suggest trying to go the ObjectManager route. ZPatterns does not have a good way at present to map child objects into other databases. Instead, a more custom approach would be appropriate, where you have say an "images" attribute that is loaded/saved through SQL. This has the downside, however, of being either resource intensive or computationally intensive. However, it'd probably be best of all to have a Photos specialist, with a getPhotosForProduct() method, addPhotoToProduct(), and so on. Actually, I can't put an Image object on a DataSkin, right? So however I store it, it's going to have to be a my own custom Image object subclassed from DataSkin... Not necessarily, it depends on your overall structure. If you want to use standard Zope Image objects you may indeed want to subclass from DataSkin. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
