[Zope] href on a local file

2001-01-11 Thread tilo . schwarz

Hi everybody,

it's now my third day with Zope and I'm already pretty happy with it. Finally I 
got external python methods running with passing parameters to them and getting 
return values back. Although there is a lot of documentation, I couldn't find 
any about the Zope internals. Does anybody know where to look for such 
documentation?

Now my question concerns local files. We do image processing and have zillions 
of images. I'd like to do some "have a page of thumbsnails and click on it to 
see the full image" kind of web page. I saw the examle thumbnail code in 
http://www.zope.org/Members/michel/ZB/ScriptingZope.html, but that code puts 
the thumbnails into the Zope Database within the python script. I'd like to 
avoid that, because with our zillion images this would bloat the database 
pretty much. 

If I got the docs right, it's normally not possible to publish a local file 
with Zope, only objects in the database can be published (correct?). But I 
would like to use a href like

A HREF="http://mymachine/images/.pgm"
IMG SRC="http://mymachine/images/thumbs/.pgm"/A

in the dtml. If I understand it right, the product "Local File System" would be 
a possibility to do that. Is it the right way to go, or does anybody have a 
better / other solution? 

Tanks for any help!

BTW: I read about dropping external python modules in some future version of 
Zope. For us, the main point with Zope is, that you can build a web front end 
for a bunch of python modules we have. Thus, from our point of view, the 
dtml-binding possibility to python modules is essential.

Tilo

Hi!

 documentation, I couldn't find any about the Zope internals. Does anybody
 know where to look for such documentation?

a) The code itself is quite well-documented ;-)
b) There are documents on zope.org on how the ZODB works and on programming
Database Adapters; I guess there is even more, but well-hidden ;-)
c) Always try the zdp.zope.org (Zope Documentation Project) site for more
stuff

 script. I'd like to avoid that, because with our zillion images this would
 bloat the database pretty much.

 in the dtml. If I understand it right, the product "Local File System"
 would be a possibility to do that. Is it the right way to go, or does
 anybody have a better / other solution?

There is a product called ExtFile/ExtImage that does exactly what you need. 
But you could also build your own solution very easily, e.g. using Apache 
(or the new Tux webserver for extra performance ...) to serve the images and 
just manage the upload via Zope/LocalFS.

 BTW: I read about dropping external python modules in some future version
 of Zope. For us, the main point with Zope is, that you can build a web
 front end for a bunch of python modules we have. Thus, from our point of
 view, the dtml-binding possibility to python modules is essential.

There is a tendency towards making more stuff available over the web (e.g. 
"replacing" External Methods by web-manageable "python scripts". This might 
make External (Python) Methods more or less unnecessary (BTW: Most of them 
could just be uploaded to Zope/the ZODB). But the full-fledged Python 
Products (or modules) you put into the Products folder will definitely not go 
away soon. That's how most of the major Zope applications are developed.

Cheers,

Joachim

"LocalFS" is a very nice product.
I would go for it.

Re: [Zope] href on a local file (you can serve files from local file system)

2001-01-11 Thread sathya rangaswamy

Hello tilo
There is a product that will allow you to serve files from the file system.
Look under external access in download area. With this you can serve your
local files without adding to zodb
