[Zope] Ann: ZWiki Web 0.2 Released

2000-05-18 Thread Chris Withers

This is my attempt at bundling up Simon's excellent ZWiki product
with all its methods in such a way that you can create a whole WikiWeb
folder by selecting a ZWikiWeb from the "Available Objects" dropdown.

It's available from:
http://www.zope.org/Members/chrisw/ZWikiWeb

ZWiki can be found at:
http://www.zope.org/Members/simon/ZWiki

The changes made we:
-Gave Manager proxy role to the ZWikiWebAdd DTML Method so that non-root
users can add ZWiki Webs.
-Renamed the permission for adding ZWiki Webs from 'Add ZWiki Pages' to
'Add ZWiki Webs'. 

If anyone can think of any problems with these changes, please let me
know :-)

cheers,

Chris

The python interfaces that Squishdot provides, some of which are

I realised that this was a necessary step before trying to add the
ZCatalog-based indexing that will be the main feature of Squishdot 0.4.0
and will enabel Squishdot to work wih Zope 2.2 as well as fixing some
bugs.

[Zope] ZCatalog OR searching

2000-05-21 Thread Chris Withers

Hi,

I have a word and I was to return objects which contain this word in
either one index or another (both textindexes).

If I do, searchResults(index1='word',index2='word') I don't get what I
want as it returns only objects that contain the word in BOTH indices.


Is there any way I can get the results I want without resorting to two
calls to searchResults and kludging them together?

Or is this the correct way to do it? (I think this has the potential to
use a LOT of memory if the results sets are large...)

cheers,

Chris

I'm pretty sure they are deleted, but not calling manage_beforeDelete
seems stupid to me. I presume this is the reason that CatalogAware
objects that get deleted like this don't remove themselves from the
catalog (leaving a nasty mess behind them...)

What's wrong with using the button that's there now? I don't see the
point of adding to the bandwidth burden by replacing it with a graphic
(some of us have to work through slow dialup sometimes... :( )

I'd prefer to see it as a manage-like tab, top-right, with a blue

That'd be all text and a coupla tiny bitmaps which are in use anyway :-)

[Zope] Zope Newbie Questions

2000-05-23 Thread Chris Withers

Hi Daniel,

Resources I'd recommend:

The Zope Documentation Portal - http://zdp.zope.org
The Zope Site - http://www.zope.org
The Zope Mailing List - [EMAIL PROTECTED]
(see http://lists.zope.org/mailman/listinfo/zope for details)

I've copied your questions to the zope list in the hope that someone
with time can help you out :-)

Good luck,

Chris

PS: Short answers:

- Try adding 'Image' objects for your graphic needs.
- With the Free Zope Hosting option, I don't think there's any way you
can do a bulk upload, but Itamar's loadsite.py utility may be able to
help...
- If you like DreamWeaver, I'd recommend our Professional Zope Hosting
option, as DreamWeaver should work fine with this...

Not quite, it's solved in a slightly different way in the CVS.

We do the following to get the CVS solution to work with 2.1.4 and

have to agree that it isn't there yet...

Unfortunately, no-one is getting paid to do it, and everyone who is
working on it would probably get fired if they spent enough time on it
to REALLY get the job done...

I reckon there's about 25 man weeks of work to do based on 5 people
spending:
-1 week to build the tools
-1 week to plan the structure of the documentation
-3 weeks to get ALL the Zope documentation linked in one place (which is
what zdp is supposed to be...)

So, has anyone got the cash? ;-)

Once this is done, it will be less work to keep that documentation up to
date. Hopefully, eventually, all documentation would end up on
zdp.zope.org and not just be linked from it...

I agree here too :(

Good luck, I think you're (or should that be 'we're all') going to need

Apparently storing a wrapped object is a security hole, I bumped into a

So, something, somewhere in your zexp has a wrapped object...

Yup. In the same way we have Python Methods, External Methods & DTML
Methods.
But no Perl 'Products' and certainly no perl in other Zope code. That
would be bad.
But from reading the FAQ that seems to be what is happening. In which

Further from this, I think diversifying the language base to
Python/Perl/XSLT/etc is bad.
It means that for someone to be 'proficient in Zope' form a marketing or
job hunting point of view, they also have to know Perl, XSLT, etc rather
than just Python and DTML.

It defocuses Zope from what it is.

I can read and write Perl if I have to, but I don't want to... it's bad
enough just trying o keep up with the stuff being done in Python, adding
Perl to that will make it nigh on impossible...

I have to say, I'm not convinced it is. Providing Perl methods is like
drilling a hole through a dyke wall. By getting loads of perl
programmers on board, you suddenly have a large userbase wishing they
can do more in perl, so you implement perl products. (yes, I've read the
FAQ too, hence my politicians comment...)

This userbase gets into hacking the core and bring perl into there.

Suddenly Zope is a total mess of perl and python and the whole community
shifts onto something cleaner leaving DC high and dry and spoiling a
perfect solution...

pessimistic, I know, but pessimism if often appropriate in computing...

I only chucked the Wiki up last night to try and structure some thoughts

I think plain mailhosts will do the sending thing quite well, they

Aquisition is to a tree of objects what inheritence is to a hierarchy of

Forgive my ignorance, but in what way is 1 correct here? Surely 2 is the

Check out:
http://www.zope.org/Members/mindlace/MailZopeMan

I like these ideas a lot, but I'd prefer to see the low-level email
integration done seperately, so it can be used for other things.

My dream would be for Zope to pipe an email address to a specific
object/method without the need for any external mail servers or
scripts...

ZMailman could then very easily be built on top of this. However, if
ZMailman is built, I suspect it'd be difficult to use the core
functionality to do something else. What is the email equivalent of
Medusa? And can we 'borrow' it in the same way?

Any takers? ;-)

If this approach would let users email content into things like the PTK,
or more generally to create Zope objects by emailing content to an
address that corresponds to a Zope method or object then that's what I'm
on about.

Archiving mailing lists shouldn't be a big issue since there are already
Zope mailing list archives that are searchable in ways currently more
powerful than ZCatalog has to offer.

If it's not necessary, then don't do it, but if it is to get true
mailing of content into Zope then lets get started on it it now so the
end result arrives sooner...

It HAS got a lot better since Tres started, but there's still a load of
cruft in there; stuff that's not completed but is so old that it's now
irrelevant.

A small point, could all searches/browsing/etc all be sorted in reverse

That way I wouldn't have to trudge through a lot of Zope 1.x problems
just to get to the stuff that's relevant.

On a more radical thought, there was talk a while back of ditching the
collector in favour of a Tracker, whatever happened to that plan?

[snip wiki change notification]

What's does NetMind actually do?

The problem I see here is getting an email everytime someone hits
update, which can mean you get a storm of emails when a coupla people
edit a Wiki.

I thought of a Zope-based solution for this but haven't had time to
implement, not to mention it requires product that's bust:

The idea is to only get notified once a day when a Wiki _Web_ has been
changed...

The folder the web is in would have a lines-type property containing the
email addresses of everyone 'subscribed' to that web. And a flag called
changed... any page changes, the flag gets set.

Once a day (needs ZScheduler :( ) a method goes and checks the flag,
compiles a message containing links to all the pages that have changed
(including being created or deleted...) and mails it to everyone in the
list.

Anyone want to implement it? ;-)

I suspect there will need to be a 0.4.3 (maybe 0.5.0) release that works
with Zope 2.2.
However I'll probably use the new traversal interface for it so it won't

Zope's not too hot on this either what with index_html instead of

This will give you the time your current object was last modified.

Why has this not been renamed to something sensible?
We lost PrincipiaSearchSource a while back, I hope this goes the same

Did someone say 'acquisition'?

You could just have one icon in the root folder and let it be acquired
:-)

As to what this icon is for:
Fire up IE and go to the bookmarks menu. See those little icons? That's
favicon. If one isn't found, the default one is used.

You have two choices: Put up with the errors and stick to your
principles, or do a bitmap and sell your soul ;-)

It makes little to no difference to IE users...

It's not so much a bug as a complication caused by the fact that Zope
isn't a filesystem server, but an orb presented through the web (correct
me if I'm slightly out ;-)

For example http://host/x/y/z

Could be:
-A container object z (which should have a / after it?)
-A dtml-document in folder /x/y/
-The result of executing the z method on the y object in the /x/ folder.
-The result of executing the z method on the result of executing the y
method on the x object in the root folder.

I'm sure acquisition adds some more options/confusions to this... ;-)

So, that's the problem, I don't know what the solution is :(

I do think there must be a better way than Zope's kludgey BASE tag
thing.
Maybe all Zope URLs should end in a / ?

Quite radical, but maybe the most sensible and least confusing? :/

cheers,

Chris

[Zope] Zope URLS

2000-06-08 Thread Chris Withers

Rik Hoekstra wrote:
> so what is the use of the /? Couldn't all Zope URLs end without a /?

I'm afraid this is the whole problem and it's caused by relative urls.

Say you're at http://host/x/y where y is a container that renders
index_html to be displayed, and in that index_html you haev a ref:

b

Now what you mean by that is http://host/x/y/b but because there's no /
on the end, you actually get http://host/x/b

How Zope handles this is by sticking in that godawful base tag:
http://hosy/x/y/">
which makes relative URLs work properly.

BUT, from what Gregor said earlier is a 'non-standard' way of doing it:
> traditionally in a static web server, if you try
> to access a URL like 'http://host/xyz' (without trailing slash), the server
> will return you an error '301 Moved permanently' and will point you to the

which is why I suggested all Zope URLs should end in / as all zope
objects can be containers in the 'traditional' sense.

Or we could just re-write HTTP to provide more useful information in the
first place ;-)

Chris

That's not very search engine friendly :(
The head should return the same type as the real document otherwise
what's the point of returning a head at all?!

The web is an imperfect medium, but returning a junk content type isn't
good.
I don't know the answer to the sideeffects thing, but I would come down
on the site of 'if you expose something through the web, you should
expect to have it spidered...' but that's cause I value search engine
hits a lot.

The trick would be to set the content type when the object is created
and have it stored in the object, not computed for each request.

Would a property suffice for that?

Then, say, if you knew your DTML method was going to return plain text,
you could set the content-type property to text/plain. Thsi could be
returned in the head without having to evaluate the object to return the
head, which is a bit innefficient.

I'm sure that's possible and better than it is now, but at the absolute
least the junk should cover the most likely outcome, ie text/html
instead of application/octet-stream, which is possibly the worst one I
can think to choose ;-)

There is a Wiki for ZScheduler which has a FAQ that covers this.

the message is just a warning and the unarchiving has worked fine...

Maybe, but not in any bad way, the worst I can see happenign is that
they try and get the same ports on your machine. Just run up one
instance at a tiem to make sure that doesn't happen (it shouldn't
anyway, but it never hurts to be paranoid)

You could also try copying the data.fs from the old install over the one
in the new install if you want to get your old data back, no reason why
it shouldn't work.

As for your error, it looks like something bad happened when zope tried
to write to the log file. Did you do any funny configuration fro your
logging? What version of Zope are you using?

Hi Hamish,

I'd suggest downloading the ZWikiWeb product from:
http://www.zope.org/Members/chrisw/ZWikiWeb

It does pretty much exactly what you're talking about. It's doesn't take
very long to knock up a product like this and I don't think I even used
ZClasses. My basis was the example stuff from the Zope Content Managers
Guide.

I'm guessing this is what you're trying to do. If you're looking into
using inheritence (so for example, your tutor changes his example, which
causes all the instances to be updated) then you'll need to use
ZClasses. I have vague memories of the Zope Developers Guide covering
this, if not, try BeeHive's ZClass guide.
