[Zope-dev] Object references from dtml
I have a log composed of sublogs, and so on. I would like for people to be able to see some kind of summary (e.g., short versions of the logs down n levels) on the screen and then click on one of interest and see a fuller display of it. Is there a good way to do this using dtml? I've thought of two approaches. The "standard" zope way seems to be to make each log folderish, and give each entry an id. Then I can embed the address in the html. The problem with this is that I would have to make up the id's and add extra machinery that the logs don't really need. I'm leaning toward a second approach, of getting an object id and putting it in the html. This also raises some issue. * Will the id be stable in the face of the db potentially dematerializing objects underneath? * If I use a persistent id (_p_oid, I think), will that be stable? * (Also, I'll need to be sure everything has persisted, but I think I can do that by forcing a transaction end before getting the _p_oid). * Can I map from object id back to object? (_p_jar.something or other) * Will this be robust across database changes (minimally, from ZODB to ZEO)? * Will the object id consist of characters which can be embedded easily in html? ___ 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] Inheritable Propertysheets!???!!?!?!?!!
Thanks, that does seem to do the trick. :) Much appreciation!! I added a propertysheets like this: ParentClass.Propertysheet.defaultProps.someprop ChildClass1.Propertyshoot.props.someprop ChildClass2.Propertyshoot.props.someprop (to override the parent's default when needed) It sees the ChildClass' "someprop" first so it doesn't go look for the parent's prop. This is useful for making lots of classes with only a few changed properties, but the bulk of which can be inherited. Alex.

The problem is that the all the propertysheets have to have different names.

If your parent class and child class do not share propertysheets with the same name, you *can* access parent properties: ChildClass.Propertysheets.ChildSheet.anotherproperty ChildClass.Propertysheets.Basic.someproperty will both work.

IMO i'd highly recommend against messing with the zodb stuff, _p_ attrs are supposed to be reserved. i understand you want to treat them as read only, but i wouldn't even go near it if it could be implemented easily otherwise or i had developed a strong masochistic tendency and already knew the zodb well (well enough to know the answers to the below questions). This also raises some issue. * Will the id be stable in the face of the db potentially dematerializing objects underneath? what id? * If I use a persistent id (_p_oid, I think), will that be stable? see above commentX2. * (Also, I'll need to be sure everything has persisted, but I think I can do that by forcing a transaction end before getting the _p_oid). transactions are important, but also telling it before hand that the object is dirty and needs to be saved. you might want to read jim's paper on the zodb. it and alot of other good material are linked from http://www.zope.org/Members/itamar/LearningZope/LearningZope.html * Can I map from object id back to object?

[Zope-dev] Method binding
Maybe the Zope-Dev guys have comments on this From: Jim Fulton [EMAIL PROTECTED] Michel, You have advocated that methods should always be bound to the objects they are accessed in. You argue that there should be no choice in the matter. I have to disagree strongly. I'll try to explain why. In Python, methods are bound to instances. Methods are part of an instance's core behavior. They are specific to the kind of thing the instance is. In my words, methods are part of the genetic makeup of an object. In Zope, we allow some methods to be bound to their context. This is done in a number of ways and is sometimes very useful. We have methods, like standard_html_header, which are designed to be used in different contexts. We have other methods, like manage_edit that are designed to work on specific instances. It would be an egregious error if this method was acquired and applied to it's context. We have some methods that are designed to bound to an instance (container, in your terminology) but that, because they are written in DTML, can be bound to other objects. This can cause significant problems. For example, methods defined in ZClasses almost always want to be bound to ZClass instances, not to other arbitrary objects. asideThere's a bonus problem with DTML Methods. When a DTML Method is invoked from another DTML Method, it is bound to neither the object it was accessed in or to the object it came from. It is bound to the calling namespace. It turns out that this is a useful behavior if the DTML Method is designed to be used as a "subtemplate". /aside There is no one "right" way to bind a method. There are good reasons to sometimes bind a method to it's context and sometimes bind a method to it's container (ie instance). There are even sometimes reasons to bind a method to a calling namespace. The principle of least surprise doesn't help here, because methods defined in Python classes don't behave the way methods defined through the web do currently. We *need* control over binding, as well as reasonable defaults. If we can agree that we need binding control, the question arises as to some details and default names. Should it be possible to do more than one binding at a time, using multiple names? If not, then I'd agree that the name 'self' should be used for either the context or container binding. If both bindings are allowed at the same time, then 'self' should refer to container binding to be consistent with standard Python usage and some name like 'context' should be used (by default) for contextual binding.

From: Michel Pelletier [EMAIL PROTECTED] Jim Fulton wrote: Michel, You have advocated that methods should always be bound to the objects they are accessed in. You argue that there should be no choice in the matter. I advocate more points than that, like being able to document python with python, no XML mixed in with a language, Py Meths working like other methods do, but yes that is one of them. My argument should be more flexible in regard to choice, a willing compromize is to switch the default binding of context and container, making 'self' the default for context and something else the default for container. I have to disagree strongly. I'll try to explain why. In Python, methods are bound to instances. Methods are part of an instance's core behavior. They are specific to the kind of thing the instance is. In my words, methods are part of the genetic makeup of an object.

In Zope, we allow some methods to be bound to their context. This is done in a number of ways and is sometimes very useful. We have methods, like standard_html_header, which are designed to be used in different contexts. this is how I feel python methods should be designed to be used. We have other methods, like manage_edit that are designed to work on specific instances. It would be an egregious error if this method was acquired and applied to it's context. I think this is a weak argument, none of the built in Zope methods mean anything to the average user, they can't find them, click on them, edit them, or copy them to their own method to change and experiment with.

It turns out that this is a useful behavior if the DTML Method is designed to be used as a "subtemplate". /aside This is because DTML binding is implicit, not because it's backward. This problem doesn't effect python methods because you allways bind a method in python when you call it. The question is how the initial method gets bound. There is no one "right" way to bind a method. There are good reasons to sometimes bind a method to it's context and sometimes bind a method to it's container (ie instance). There are even sometimes reasons to bind a method to a calling namespace.

We *need* control over binding, as well as reasonable defaults. If we can agree that we need binding control, the question arises as to some details and default names. I agree there must be control over binding, although your arguments above have not convinced me that Python Methods are doing it the right way, actually, it's convinced more than my argument, compromisingly of course, is more right. Should it be possible to do more than one binding at a time, using multiple names? If not, then I'd agree that the name 'self' should be used for either the context or container binding. I'm with you so far with that. If both bindings are allowed at the same time, then 'self' should refer to container binding to be consistent with standard Python usage and some name like 'context' should be used (by default) for contextual binding. That's what I disagree with. I don't think you've given a strong corollary to standard python usage. The only strong argument you've given so far is the ZClass one, but 10 gives you 1 that's not the primary use case (it may be the one in Fburg). People are going to be defining these methods in Zope to make their lives easier, probably bad design and mad hacks and no structure, but that's how 90% of the world gets their work done and easing that burden is the usability task. You have not convinced me that: 1. Something called a Python Method should not resemble a method definition in python. 2. Something called a Method in Zope should not behave like the other Methods (meaning through the web objects) in Zope 3. Common, *documented* well understood URL manipulations (context) are less important than (the less common) containment oriented design and ZClasses.

[Zope-dev] Python and Perl scripts
This one is probably the most useful of the lot ;-) From: Michel Pelletier [EMAIL PROTECTED] Greetings, Well, Jim, Evan, Brian and I pow-wowed yesterday and came up with an interesting change. The world 'Method' is too overlaoded, as it means too much to too many people. Also, Python Methods don't work like methods in python, which was my argument, but they are very useful and there are sound reasons for them working like they do (which J, E and B convinced me of yesterdat). We have decided to change the name of Python Methods to something else, the current candidate being 'Python Script'. 'Script' objects make a lot of sense, they don't overload the concept of methods, they describe an action that people commonly want to do (script the web) and they clear up a lot of potential confusion for newbie and old-hat alike. The bonus for all of this is that the only thing that needs to change is the name. Which name is still an issue though, and we want your input. what do you think of the idea of Perl Script objects? The other issue, for the sake of documentation, is variable binding (which was the root of our disagreement yest. Python Methods do not bind variables and argument like methods in python do). From what I can see, Perl Methods seem to get 'self' pass in as a first argument. Is this all there is too it or are there more details? Python Methods have five special variables (defined on the bindings tab) that get created in the namespace of the method. Should perl methods work the same way and not have special variables passed in as arguments? This would probably be more consistent with the Python model, and since 'self' will probably not be the name of the variable bound to either the container or the context it should be more explicit for perl methods also.

We have decided to change the name of Python Methods to something else, the current candidate being 'Python Script'. Well, I think script ain't right. How about 'Function', since, to me, the things you've described sound exactly like normal Python Functions. A function is callable but has no logic about a magic 'self' argument or anything else, for that matter. methods, they describe an action that people commonly want to do (script the web) and they clear up a lot of potential confusion for newbie and old-hat alike. 'script' implies a sequential execution of a lump of code that doesn't 'return' anything. That doesn't sound like the old Python Methods. They get arguments (from the namespace, some of which is introduced by the bindings tab) and return something, probably text, that results from their execution and, I guess, their return statement. Just to overstate the point (;-), that sounds like a function to me... Python Methods have five special variables (defined on the bindings tab) that get created in the namespace of the method. Should perl methods work the same way and not have special variables passed in as arguments? Sounds like they should have a binding tab and no 'special' self argument. Maybe they should both subclass a generic 'Function' object which provides the interface for this?

Actually, I am not sure that script is much less technical than function. I think script, as in bash script, or scripting language is very crabbed and technical indeed. The only pre-computer usages I know of script(n.) are indicative of a cursive style of writing, apeper money, or a thing that playwrights produce. I don't think that playwrights are going to suddenly start wanting to use python! I think that script, as in "scripting language" is simply something that most people indeed do not get! The new DC documentation motto is "Explain key ideas in simple terms." Method is not a simple term. I don't disagree with your goal. I do disagree with this particular choice of words. I can see four potential properties that one could want to emphasize about a python method. 1) It is safer (to the Zope server) than a python external method. 2) It safer to the end user than a JavaScript (it never touches the client). 3) It uses python, and not something else as its implementation technique. 4) In OO terms, it is not really a Method. Hence the preference for Safe in the name. Even a newbie ought not to be able to cut himself too badly on a python method. There is talk of perl methods. So we need python in the description. Now we just need a generic term, which will not cause other confusions later on down the road for the concept. I really don't like script, especially next to a language name (in the web domain). You don't like function (which was not my suggestion). Thingie seems a bit too non- descriptive. Widget has technical meaning.

Michel Pelletier wrote: Keep in mind also that we are moving towards a new architecture with "Documents" and "Templates" (ala HyperDOM). I think Scripts fits right in there: Documents, Templates and Scripts or Documents, Templates and Methods I tend to think of things as: Objects, Views (or Templates) and Blocks. The diference (for me) between a View and a Block is whether they are intended to be accessed directly by a client (browser). Blocks also tend to be reuseable in many views (I typically have a Block (DTML Method) called main_navigation, for example), and can be composed of other Blocks. Views like index_html may be reused, but usually through acquisition, not recomposition. The lines are fuzzy though, since I'm usually using the same types of objects (DTML Methods) for both Views and Blocks. Perhaps we need an object type that is not directly accessible from a client (but may only be called or rendered from other objects) in order to clarify the distinction.

[Zope-dev] Re: [Zope] IIS and PCGI
Well I fixed this using a ISAPI filter which I will release soon (once I have some time) that takes a url /a/b/c/x.pcgi/f/g/h, and passes /a/b/c/x.pcgi to IIS so the file will run and /f/g/h to Zope. My next question is has anyone succeeded in getting this to work to another box over a mapped or shared win32 drive? I mapped g:\ to my zope host, and then specified PCGI_PUBLISHER=g:\pcgi\pcgi_publisher.py in my pcgi file. The problem seems to pcgi-wrapper.exe which does not like a mapped drive.

I think I checked all of the following: * the file was getting updated * all instances of explorer were shut down * MSIE options set to "Check for newer version of stored page on every visit to the page" A notable peculiarity was that whenever I tried to access my local zope, I would get a "you are offline, do you wish to go online" message (I even used localhost as the machine name!).

It is not safe if you have malicious users. You will need to pass your dtml-var name="search_field" through a filter. This will help. A better example is a user taking advantage of an insert method: insert into data values (dtml-var name="value_1", dtml-var name="value_2", dtml-var name="value_3") where the user has found the Zsqlmethod by looking at http://yourzopehost/objectIds and calls it like this: http://yourzopehost/sqlADDUSER?value_3=randomvalue);SELECT%20*%20FROM%20secr etpasswordtable/ Fortunately, Zope responds with a "testing the sql method" form if you are authorized.

Hi, Robert BTW, this is a FAQ, but: use the :list extension in your html. e.g., select multiple name="dtml-var form_save_name:list" dtml-in thelistitems option value="dtml-var sequence-item"dtml-var sequence-item/option /dtml-in /select Works for checkboxes, too! -- Jim Washington Robert Joseph Roos wrote: dtml-expr="_.type(some_variable_of_unknown_type)" causes a name error, while other python builtins like _.string(some_int) work fine. What gives? Is there some other "zopist" way to type-check? More generally, is there a better way to deal with the annoying fact that multiple selectors return a list UNLESS there are =1 items selected, in which case they return a single item or None? (rather than a list with only one member, in the case of 1 object selected, or an empty list, in the case of none, which would SEEM to be the consistant way to do things, since dtml-in wouldn't choke.) ___ 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] O'Reilly Book Tecnical Reviewers
Greetings, O'Reilly is looking for 4 or 5 technical reviewers for the book. http://www.zope.org/Members/michel/ZB/ Technical reviewers get paid either a small honorarium or get free copies of the book (I am unaware of the exact details). I'm sure this message will elicit a *flood* of candidates, and I'm afraid we can't accept them all (of course, that doesn't mean you can't do it for free ;). Further, this will be a time consuming task, requiring you to scrutinize all details, try examples, etc. You will probably give more effort than you are monitarily compensated with, but you will also get unending glory and mucho zen master points from your zopista peers. So please consider this opertunity to work directly with us to make a great book. If you are interested in the sweat and the glory, please send an email to [EMAIL PROTECTED] with the subject "I Wanna Be A Technical Reviewer", and maybe a brief bio about you, your Zope experience and (bonus points) if you've every technically reviewed a book before.

[Zope] Acquisitive
Hi Zope Fans, I ran into an odd quirk today, and I'm hoping someone has an insight to share. There is a simple text string stored as a DTML Method, with ID = "set_table_0", e.g.: 'border="0" cellpadding="0" cellspacing="0"' When set_table_0 is in the Zope root folder, it isn't discovered through normal acquisition, but no error occurs. table dtml-set_table_0; creates a table with defaults, e.g. border is visible. However, when set_table_0 is moved to a subfolder of the Zope root folder, with the name "table_settings", and the reference is made like so: table %dtml-table_settings[set_table_0]; the DTML Method is found successfully, and the table border isn't displayed. The question is, why is the folder "table_settings" found in the Zope Root Folder, but not the method? Does Acquisition give higher preference to folders (container), objects than a DTML Method?

[Zope] Acquisitiver and Acquisitiver
OK, now I'm really confused. I stumbled on a way to make the DTML Method work, that is, the one that wasn't being found before, via Acquisition. All I have to do is forget to add the terminating ';' in : table dtml-set_table_0; so that it looks like so: table dtml-set_table_0 Any guesses?

[Zope] GUF error: Unauthorized...
Hi!
I have created a GUFTest folder. It runs perfectly with the user
'jorge', provided with the GUF. After I have changed the acl to use a
SQL connection, I'm getting the error bellow (in the log of the system):
GUF[7909]:
http://localhost.localdomain:8080/GUFTest/acl_users/userAuthenticate
raised an exception (('Unauthorized', 'crypt', traceback object at
85f10e8))
The source of the HTML page contains (I don't know if it's correct,
because I suspect that Netscape reloads the page when you ask it to show
the source of the page):

are configurated to proxy the Manager role.
I'm using Zope 2.2.1, on a Conectiva Linux 5.0 (Linux i386 2.2.14,
python 1.5.2, glibc 2.1.3).

Re: [Zope] IIS and PCGI
Well I fixed this using a ISAPI filter which I will release soon (once I have some time) that takes a url /a/b/c/x.pcgi/f/g/h, and passes /a/b/c/x.pcgi to IIS so the file will run and /f/g/h to Zope. My next question is has anyone succeeded in getting this to work to another box over a mapped or shared win32 drive? I mapped g:\ to my zope host, and then specified PCGI_PUBLISHER=g:\pcgi\pcgi_publisher.py in my pcgi file. The problem seems to pcgi-wrapper.exe which does not like a mapped drive. (line 485 of parseinfo.c keeps spitting out missing publisher)...
