Resize a image stored in a Oracle's BLOB Field
by Juan Javier Carrera Obrero 27 Nov '01

27 Nov '01

Hello, Thanks, I have displayed the images which them was stored in a Oracle's BLOB field, with: <dtml-call expr="RESPONSE.setHeader('content-type','image/jpeg')"> <dtml-in SQLMethod_with_a_Only_Row> <dtml-var expr="BLOB_FIELD.read()"> </dtml-in> However, I would like to resize this image. I can not do it with the "height" and "width" attributes, because the image is obtained from a Oracle's BLOB field, and no from image object (i.e.: I can not use <dtml-var "ImageObject.tag(border='5', align='left')">). How can I do it ? Thanks again !

Re: [Zope-dev] Acquisition wishlist :-)

As a side effect to turn off acquisition, you defined the attribute. This will not play well with inheritance: You will not only prevent acquisition of "index_html" but also prevent inheritance of it (which may be really necessary in some contexts). Dieter

Alternative Storages: (was RelationalStorage (was LocalFS))
by Jimmie Houchin 09 Jun '00

09 Jun '00

This was on the Zope list and I've move this to Zope-dev as I feel it is more appropriate. I have been making notes to myself for awhile with ideas about things I would like to explore with Zope Storages when I am able. I have not posted any of them since talk is cheap. But I guess since I'm full of cheap talk I'll let it go. :) I'll also post this to the ZODB zwiki after I see what's left standing after analysis. :) As far as usage is concerned I generally like the ZODB best because it is reasonably transparent to the building of a web app with Zope. However there are areas in which it does not currently excel that which if your site requires these skills then alternatives must be used. A couple of areas are data size and heavy writes. Some people use an RDBMS to solve these issues. While this will work it does expect more from the developer. Some do not have the skills or the tools. Even if one does it still requires leaving the transparency of developing with the ZODB. Multiple file storage for the ZODB has been proposed as a solution and there are 2 proposals currently on the ZODB ZWiki. I will add another. Class/Object based db files. Each class gets it's own db file. This could be similar to the current ZODB file except specific to a class. As objects are created they are appended to the db file for their class. This could be somewhat analogous to tables in an RDBMS. Advantages would be spreading out the data space over multiple files which would help with some oses. Also I think that each class has different characteristics which would be able to be managed better if separate. Example: AutoParts You have an AutoParts class. The objects will change very little once created. However there are a lot of objects and news added periodically. This file will need packed seldom. It will also be simple to backup and not need backed up often as changes are periodic and regular. RetailStore In a retail store the product objects are very volatile. Vendors can change. Prices do change. A productObject file would have different usage characteristics than the AutoParts object. Some classes are perfect for few writes and many reads. Others less so. Earlier Andrew Kuchling was wanting to walk the object tree. This would provide a relatively easy way to walk the object tree. This could be implemented with some support classes which have to be inherited from to create a class.db file. Any class not so doing would go into the standard ZODB. This could help provide desired management features for the characteristics of each. It would be nice if in the management you could set the path to the file. This would allow for multiple disks or partitions for data storage. This too would help with backups and such. Just a few ideas. They may not stand up to examination, but that's okay. I just thought I would put them on the table.

New Help System in 2.2
by Jason Spisak 07 Jun '00

07 Jun '00

Michel, I was just browsing the help system and can I just say it is terrfic. The .py files especially. Not that python isn't that easy to read, but having the ZQR type stuff handy online is a huge win. Is that stuff updated fro mthe source on the fly? Greatfully, Jason Spisak CIO HireTechs.com 6151 West Century Boulevard Suite 900 Los Angeles, CA 90045 P. 310.665.3444 F. 310.665.3544 Under US Code Title 47, Sec.227(b)(1)(C), Sec.227(a)(2)(B) This email address may not be added to any commercial mail list with out my permission. Violation of my privacy with advertising or SPAM will result in a suit for a MINIMUM of $500 damages/incident, $1500 for repeats.

Import from upload?
by Sin Hang Kin 05 Jun '00

05 Jun '00

Hi, I have just come acroos this idea of having zope accept the import file from an upload form instead of having it from the server directory. In web hosting environment like imeme.net, It is painful and unsecure for all to share the import directory for updating.

TextIndex Questions

How do you use the query language and return the relevance rating from a ZCatalog query? Is it documented anywhere? also, which of FieldIndex, KeywordIndex and TextIndex is case sensitive on matching? I thought they all were but I'm not sure anymore... cheers, Chris

Grab a copy of the >latest version and search for 'WooHoo' in GenericUserFolder.py Been there, done that. Yours doesn't work either, btw. Well, actually, it does, it's just that it causes a memory leak because it leaves an unintended circular reference. We've got a version that fixes the circular reference, but in a really really ugly way (it does a run-time patch to BaseRequest.close() to remove the poked-in unauthorized() method). It will be in LM 0.8.6, which we're trying to finish now. We might have had it done today, but there was a bomb threat in one of the buildings in the complex where we work and we were evacuated for a couple hours. LM 0.8.6 also works with Zope 2.2 as far as being able to be added, although I'm not sure it interoperates properly with the new security API. It will still be backward compatible with Zope 2.1.6 either way, though.

What causes the failure
by Robin Becker 02 Jun '00

02 Jun '00

After updating with the latest CVS patches my formerly working installation now fails with an Authorisation failure. Before I didn't need a password at all; now even the manager password fails. Please ZOPE developers, can't we get some information into the trace back about what object/permission is causing this kind of failure. Zope Error Zope has encountered an error while publishing this resource. Unauthorized You are not authorized to access this resource. Username and password are not correct. Traceback (innermost last): File C:\Python\devel\Zope\lib\python\ZPublisher\Publish.py, line 224, in publish_module File C:\Python\devel\Zope\lib\python\ZPublisher\Publish.py, line 189, in publish File C:\Python\devel\Zope\lib\python\ZPublisher\Publish.py, line 161, in publish File C:\Python\devel\Zope\lib\python\ZPublisher\BaseRequest.py, line 460, in traverse File C:\Python\devel\Zope\lib\python\ZPublisher\HTTPResponse.py, line 560, in unauthorized Unauthorized: (see above) I found one problem already when I found that apparently my permissions for tiny tables had been modified somehow. In that case I could see the name of the tiny table that was being requested in the traceback. This permissions model is already far too complex; without random changes being introduced as the model is hacked. -- Robin Becker

It should be possible to register Local Directory with all_meta_types in the product initialization but that might have undesirable implications. For one, I wouldn't want it to show up in the 'Add Objects' list. Option 2 might work.
