Where are user created help files stored?
by Jason Cunliffe 10 May '01

10 May '01

Zope2.3.2 Win98se/Redhat6.2 I am upgrading the READMEs for a simple Zope Product. I clicked through the ZMI /Control_Panel/Products/ to add some help files. Very nice :-) An example where TTW simple editing really makes sense. I added two help pages for: 'install' and 'use' easily called like this: http://jasonic/Control_Panel/Products/BSDObject/Help/use Then I uploaded my Product folder to remote Linux setup. Works fine but my help files are not there :/ The principle seems obvious to me -help files belong in each Products own folder. Where are the help files kept? Various searches show lots of other help folders but not for my product. Am I doing something wrong or is the workflow for this not yet well developed? Seems like a another vote for a consistent basic Zope Product maintenance API like HiawathaZ[Zope Beans] ? http://www.pault.com/pault/prod/Hiawatha/HiawathaZ.html Also I am curious why does HiawathaZ proposal use separate non-python XML tools? thanks ./Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

Can you give an example to do this please. .................................... More wishlist suggestions for Zshell. <note> I aplologize only a little for this experiment in blatant featuritis. In many cases this is not rocketscience, but a apprades to be a matter of writing smart user-friendly wrappers around known zope tricks. The shell paradigm is very good and does nto really interfere with the nature of zope. Perhaps those with deeoper zen than me will see the catch. I beleive many of the practical workflow headaches of using Zope among different people[skills], can be solved by growing the Zope shell. It separates function from syntax in a very simple way. Logic is another question... If nothing else, I suspect zopeshell is more concise, and readable to more people out of the box. Also very extendable. A fascinating and useful experiment imho. </note> --------------------------- 1. MORE SHELL-LIKE BEHAVIOR I keep hitting return and expecting my code to happen. It's not just laziness. The RUN button breaks the familiar shell command line paradigm. I realise it is nice to have multiple lines, but I find it faster to type and keep typing, than have to jump back and forth to the mouse. One solution: SHIFT + ENTER => multiline entry ENTER => execute ----------------------------- 2. ZSHELL DTML UI SUGGESTIONS At the top of the page include all the wget commands as hyperlinks links. Clicking on a command displays the docstring for the command above/below the text area and also enters the comand and dummy argument string directly into the Zshell shell where one may edit. A checkbox option next to the textarea toggles the 'auto_insert' feature 'on' or 'off'. 'Off' displays just the docstring for the clicked command above the text area This kind of behavior and its display should be defined in any .zrc file and should be able to be invoked in the zshell. Thus display_commands # show hyperlinked zshell commands above text area auto_insert_off # jsut the man docstring auto_insert_on # insert commands and dummy args save_zrc [name] # save the present zshell dtml UI into .zrc file # [zodb/tinytable/properties?] load_zrc [name] # load a .zrc conifiguration DTML + ZSHELL Add a new tag so that Zshell commands can be run from DTML A trivial example might go like this: <dtml-zshell> mkdir ../artists/$newartist cd ../artists/$newartist adduser $newartist/QWERTY mkdir newprojects/outline wget http://www.newsartists_website.org/work/outline pwd ls </dtml-zshell> This would create a new folder for the value of $newartist, a [yet to implemented] zopeshell variable, which can also passed in by a form or some DTML Then add a newuser, and then upload load some HTML+graphics they already have prepared online somewhere else. ------------- 3. RESULTS Normal shell would return the results in the shell itself. I can see why in Zope this may not be often such a good idea. For example, making ls return a hypelinked table as you do is terrific idea. But I found that I quickly needcd to jump back and forth between repeat commadnds when usign zshell. What I was missing was being able to scroll up and down a familair shell windows, browse and cut''n'paste. A possible solution: Allow one to concatentate results to allow a single long scrolling one. This could be a callable 'zhell_session_RESULTS' DTMLmethod. I think this would allow one to be even more prodcutive in using Zshell to explore and manage a Zopesite. Presumably RESULTS connected to the machanism for history you are working on... As above, one shouldbe able to configure this from the shell and/or .zrc: RESULTS_join RESULTS_single RESULTS_off RESULTS_save [name] RESULTS_load [name] I suppose addressable RESULTS are instrinsic to any piping mechanism... and thus wildcards, 'ls', 'cp' etc.. ------------------ 4. cd Seems a little inconsistent at the moment partly becuase it does not resolve "/" I have a zshell in zope root "/" cd . Results: cd: New folder is / cd /images Results: cd: Incorrect path /images WARNING: Errors were encountered but cd images Results: cd: New folder is /images Both of the above should be valid. Perhaps you disagree.. Also for any CD command which is not valid, I suggest including a 'pwd' by default in the first line of the Results error message: <zshell> cd happy </zshell> Results: cd: Incorrect path happy WARNING: Errors were encountered --------------------- 5. mkdir improvements mkdir to handle a path option to complement cd from above mkdir needs option flags to match the manual setting in ZMI of the 2 checkboxes for Create public interface Create user folder mkdir newfolder -(p)ublic -(u)ser Not sure what syntax would be best for doing this when creating a nested mkdir: mkdir a/b/c/d -(p)ublic -(u)ser possibly: :set public+user attributes for all new folders :set public+user attributes for just the last folder Perhaps control it using a simple binary flag style. For example: mkdir a/b/c/d -p0110 -u1110 Set 'public' b and c only Add 'user' folders in a,b,c only -------------------- 6. cp Of course 'cp' should work across folders and also be able to paste in one line. Perhaps a lot of work. I don't know. And I hope zope acquisition logic does not mangle this. Needs to include wildcards of course cp ../../images/earthrise.jpg ../graphics/earthrise.jpg -------------------- 9. wildcards Obviously full Shell-type regular expressions, though desirable, might be a big deal. Some useful, obvious ones for ZopeShell wishlist whcih might be much easier I can think of: * *meta *date *date_since *date_before *size_under *size_over *owner *property Examples of wildcards using ls: ls *.jpeg # object whose names end with ".jpeg" ls *meta='Image' # objects of meta_type 'Image' ls *date='06-May-2001' # objects made on 6th May, 2001 ls *date='today' # object made today ls *date_since='01-05-2001' # objects made since 5th January ls *date_before='01-05-2001' # objects made before 5th January ls *size_under='50kb' # objects less than 50kb ls *size_over='500kb' # objects larger than 500kb ls *owner='nikola' # objects owned by nikola ls *property='description' # objects with a description property -------------------- 8. wget Very useful for all kinds of things Change the 'fname' code so that the default behavior is to save names under their original source names. If that id is already taken, then take action and rename. Include an flag for Zope wget to do auto renaming [like it is now]. syntax could perhaps be: wget args rename_meta # rename to append meta tag wget args rename_sub # rename to append subtype wget args rename_xyz # rename to apend _xyz # where _xyz are any continuous suffix string, "_bak" etc. 7. adduser This is going to be very cool but, meanwhile I am not not clear what to 'do' with adduser. At least until there is a Zshell mechanism to get and set permissions, and then pass them to the add user command. I confess I don't really understand Local Roles in Zope either yet :-( ..so I better shut just up and do some more homework. > * I can't make chown to work, do you have got any idea ? not yet.. cheers ./Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

Re: ZCatalog & resource not found error
by Tim Moore 10 May '01

10 May '01

No, I'm afraid that's not it...the code below gives an attribute error, and I have other scripts where I call getObject on a brain object and have no problems...I think this and a few other methods on the brain objects were added in Zope 2.3. Even this fails: results = container.Catalog(meta_type='Broadcast', getStartTime=DateTime(), getStartTime_usage='range:min', sort_on='getStartTime') result = results[0] return result And the strange thing is that it's failing on the last line (i.e., the return statement). If I change that line to return a dummy string then there's no problem. I could swear that I had something analogous to this working before...is there a bug? I tried upgrading to 2.3.2, but that hasn't helped. :-( Chris McDonough <chrism(a)digicool.com> writes: > The objects returned in the sequence returned from > Catalog.searchResults are "brain" objects.

Your zope installation can be put where you decide you want to put it. You can even just decide, if you feel so inclined to just run it as a normal user in your personal UNIX home directory. As long as file permissions are set up in a manner so that the user you have Zope running under has permissions to read and execute stuff in Zope's lib/ directory, and that there are permissions to write to files in Zope's var/ dir. Keep in mind that everything you put into Zope, for the most part, resides in the object database, which is a single file called data.fs, always open for reading and writing while Zope is started. Your Zope installtion has nothing to do with your Apache document root, and can be put anywhere on the file system (and inside the doc root is obviously not a good idea). You can then access Zope either directly with its builtin web server (ZServer), or use Apache via PCGI or mod_proxy (proxying to Zope's builtin web server) as a front end to Zope. Zope's ZServer has a built-in FTP server, and supports Web-DAV and XML-RPC through its web server. What you actually ftp to is not your UNIX filesystem, but the hierarchy of the Zope object database presented as a filesystem. As for getting images into a database, consider looking into a python script called "loadSite.py" - it loads a site hierarchy from a file system and puts it into the ODB: http://www.zope.org/Members/itamar/load_site Sean -----Original Message----- From: Ben Ocean [mailto:zope@thewebsons.com] Sent: Thursday, May 10, 2001 8:01 AM To: Tino Wildenhain Cc: zope(a)zope.org Subject: Re: [Zope] Two Questions: One Easy, One Not At 05:13 PM 5/10/2001 +0200, you wrote: >IF you want to use your images from zope, you have to import >them into its database.

Create object inside newly created container?
by sean.upton＠uniontrib.com 10 May '01

10 May '01

Inside a python product, I have a class that subclasses OFS:Folder, and upon TTW instatiation of this object, I want to have a ZCatalog instance called 'Catalog' created within this new folder. Is the appropriate place to put code to do this within the class __init__() or within the module's manage_add...() method? What would one use to obtain the namespace of a newly created object after it is set in the ODB via _setObject()? I assume that after calling _setObject() in manage_add...(), that one could traverse into the namespace of that object, and call manage_addProduct['ZCatalog'].manage_addZCatalog()... Any thoughts?

Two Questions: One Easy, One Not
by Ben Ocean 10 May '01

10 May '01

Hi; The easy question: I have all sorts of images on my server that I want to copy into the appropriate folder in my Zope installation so that they can appear on the site that I am building with Zope. Trouble is, I can't find the folder, even when I walk the directory tree. Where does Zope put the folders I create and what does it call them? Is it possible to do what I want to do? The not-so-easy question: For some reason my Zope server dies regularly. I have root access on my RH6.2 box. When I run a process table, it appears that Zope is spawning several processes. In reality, if I try to kill the processes, I find that they're not active (nothing to kill). However, when Zope dies, all the *processes* die with it. I'm no programming guru, so any suggestions would be appreciated! TIA, BenO

Security Problems?
by Phil Harris 10 May '01

10 May '01

All, I've got a sneaking suspicion that there are some security problems in Zope 2.3.x. I've been trying to make a simple testcase and would like other (better) minds than mine to look at it. I have an external method which looks like: class c: def __init__(self,a): self.score=a self.test=a*a def t(self): retval=[] for a in range(1,10): retval.append(c(a)) return retval The class 'c' is a very simple class, it has no methods and only two attributes/properties 'score' and 'test'. The external method 't' is also very simple, it just returns an array of class 'c'. The dtml-method I'm using to access this array is as follows: <dtml-var standard_html_header> <dtml-in t> <dtml-var "_['sequence-item'].score"> </dtml-in> <dtml-var standard_html_footer> Nothing earth shattering there either. BUT, I get an unauthorized error raised with this traceback whenever I run this dtml-method: (note that a authentication login box is presented but NO user name is able to authenticate) Traceback (innermost last): File D:\ZOPE_T~1\lib\python\ZPublisher\Publish.py, line 223, in publish_module File D:\ZOPE_T~1\lib\python\ZPublisher\Publish.py, line 187, in publish File D:\ZOPE_T~1\lib\python\ZPublisher\Publish.py, line 171, in publish File D:\ZOPE_T~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: index_html) File D:\ZOPE_T~1\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: index_html) File D:\ZOPE_T~1\lib\python\OFS\DTMLMethod.py, line 189, in __call__ (Object: index_html) File D:\ZOPE_T~1\lib\python\DocumentTemplate\DT_String.py, line 538, in __call__ (Object: index_html) File D:\ZOPE_T~1\lib\python\DocumentTemplate\DT_In.py, line 717, in renderwob (Object: t) File D:\ZOPE_T~1\lib\python\DocumentTemplate\DT_Util.py, line 334, in eval (Object: _['sequence-item'].score) (Info: _) File <string>, line 0, in ?
