Xron Product Screenshots [was: Importable Xron]
by Loren Stafford 11 Aug '00

11 Aug '00

> I have in a recent email to the mailing list urged all Product creators to > include screenshots and/or demos of their products. > I'd like to put some screenshots the management pages in the README.txt of Xron where they would illustrate that text that explains those pages. Can you point to any examples of other products that do this effectively. Authors often (well I do anyway) use the same README.txt for the README tab of Control Panel / Products and for the "Release Information" link on the www.zope.org/Members product page. Being able to use the same file makes documentation easier for developers, and that's important; if documentation is needlessly hard, it won't get done. However, if I create image hyperlinks that work on http://www.zope.org/Members/lstaffor/Xron/README.txt , they won't work in the context of Control Panel / Products. I don't see to make links work correctly in both places. Does anyone know how? -- Loren

RE: [Zope] Using Zope as App Server for non http-Protocols
by Chris McDonough 11 Aug '00

Phillipp, First, design your system. Then write the very basics of what you need in Python first using whatever third-party binaries you need to, leaving the methods which use Zopish features (like ZSQL methods, ODB, etc) as stubs. Then after you're done, and it works, you can wrap it in a Zope Product. There's not much information on how to do this, I'm working on material for a Product Developer's Guide now. Authentication should probably be handled outside Zope in your Python code. Unless it's not. :-) -----Original Message----- From: Philipp Auersperg [mailto:zope@philosoft.at] Sent: Friday, August 11, 2000 5:31 PM To: zope(a)zope.org Subject: [Zope] Using Zope as App Server for non http-Protocols We want to (mis)use zope as an application server servicing a proprietary non-http protocol for transmitting compressed data. Our idea is a specially written client that connects on a proprietary port to zope where a special product is listening and serving the request. Our question: How can I implement a product listening on a specific port and servicing requests and sending back binary (in our case compressed) data. But the product should of course be able to use the infrastructure of Zope (ODB,External methods,ZSQL methods...) Another question is how does the authentification work for such a non-http connection. Any hints? Thanks in advance Philipp Auersperg

retrieving data from REQUEST.form
by jesse 11 Aug '00

11 Aug '00

I am creating a program, yet again. How this works is, a zope factory calls a form, which submits data from a <textarea> to a DTML document. I want this DTML document to take the data from the form and display it on multiple lines. For instance: If a person fills out the textarea like so: First line second line third line I want the DTML document to print out: First line second line third line The only problem is, when the <textarea> submits to the document, (lets say the textarea is called list), it submits it as a dictionary. That means all the data is on a SINGLE STRING. So the data from the form looks like this. <dtml-var "REQUEST.form"> = {'list': 'first line/015/012second line/015/012third line'} the /015/012 represent the line breaks. Seeing this, i used the replace function in zope, trying to replace the line breaks with <br>, which would be accepted by html. however, whenever you try and access the information in the form as a string... <dtml-var "REQUEST.form['list']"> it comes out with line one line two line three All the line breaks dissapear! So there is nothing to replace! Does anyone have any ideas how I could solve this problem?

<dtml-with> namespace conflict question needs explanation
by Jason CUNLIFFE <jasonic＠nomadicsltd.com> 11 Aug '00

11 Aug '00

Hello Please can someone help us understand how to avoid DTML method names conflicting with other zope objects with same name. For example using Zope export/import during recent site development to transfer work from local machines to the linux server broke sections of our site in a manner which was very hard to find. The reason we have finally traced to namespace conflict. We imported code which included calls to a local zope object named 'swf' for simple substitution. But suddenly our code did not work. It turned out that another object identically named 'swf' was an already existing 'folder' ..!! This is a very disturbing discovery, becuase it implies that one might have anywhere at anytime hidden or visible namespace conflicts emerging and vanishing with no control. We had thought that <dtml-with something></dtml-with> would avoid this. But it does not and may even cause it! It also implies that makes development of Zope sites across various machines very hit-or-miss Please help.. Exact code dump follows... 1. I have an original DTML template called 'objembedswf' in a folder named 'Flash4' <OBJECT ID='login' CLASSID='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' CODEBASE='http://active.macromedia.com/flash2/cabs/swflash.cab#version=3,0,0 ,0' WIDTH=<dtml-var width> HEIGHT=<dtml-var height>> <PARAM NAME='Movie' VALUE='<dtml-var swf>'> <PARAM NAME='Play' VALUE='false'> <PARAM NAME='Quality' VALUE='best'> <PARAM NAME='swLiveConnect' VALUE='true'> <PARAM NAME='menu' VALUE='false'> <EMBED NAME='login' mayscript='mayscript' SRC='<dtml-var swf>' swLiveConnect='true' WIDTH='100%' HEIGHT='100%' salign='t' quality='best' play='false' menu='false' TYPE='application/x-shockwave-flash' pluginspage='http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_ Version=ShockwaveFlash'> </EMBED> </OBJECT> 2. Below this my DTML file includes calls to this template like this: <dtml-with Flash4> <dtml-call "REQUEST.set('swf','login.swf')"> <dtml-call "REQUEST.set('width','100%')"> <dtml-call "REQUEST.set('height','100%')"> <dtml-var objembedswf> </dtml-with> 3. Here is the result of substitution returned in browser <OBJECT ID='login' CLASSID='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' CODEBASE='http://active.macromedia.com/flash2/cabs/swflash.cab#version=3,0,0 ,0' WIDTH=100% HEIGHT=100%> <PARAM NAME='Movie' VALUE='<Folder instance at 8557b00>'> <PARAM NAME='Play' VALUE='false'> <PARAM NAME='Quality' VALUE='best'> <PARAM NAME='swLiveConnect' VALUE='true'> <PARAM NAME='menu' VALUE='false'> <EMBED NAME='login' mayscript='mayscript' SRC='<Folder instance at 8557b00>' swLiveConnect='true' WIDTH='100%' HEIGHT='100%' salign='t' quality='best' play='false' menu='false' TYPE='application/x-shockwave-flash' pluginspage='http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_ Version=ShockwaveFlash'> </EMBED> </OBJECT> I draw you attention to the fact that <dtml-var swf> was supposed to be subsituted with 'login.swf', but instead became <Folder instance at 8557b00> ..ouch.. 4. The reason appears to be that there is a namespace conflict elsewhere in my Zope tree. As it turns out, we have a folder right under / called 'swf'. In fact it could be many places and still cause a conflict. This 'bug/feature' is the same under Zope 2.1.6, and Zope 2.2.0 in Win98se and LinuxRedhat. Is it something about <dtml-with> or perhaps our use of <dtml-call "REQUEST.set> which creates this unpredictable and confusing effect? Is this is a bug? As it stands it means is is very hard to have people working on separate sections of a Zope site because at any time they might be causing namespace collisions like this. In our case the effect was obvious - our swf files immedaitely woudl not display. But other voodoo could easily occur which migh not appear for some time. It provokes me to ask simply what is the search path priority of object acquistion in zope and how do you control it safely? Thank you - Jason Cunliffe

Folks - Federico sent me a patch for the popy-1.3.3 source. I needed it to tell it where the postgresql libraries are..if you need it please let me know and I will send it along. You may also find it in the archives from earlier this month. - Steve On Fri, 11 August 2000, "Hung Jung Lu" wrote: > > --- In zope(a)egroups.com, ed colmar <element@i...> wrote: > >Hi, I downloaded the current versions of ZPoPyDA, and PoPy from > >www.mixadlive.com, and I cannot figure out how to execute the installation. > > Run the autogen.sh script first, instead of the ./configure. > > Could you send an e-mail to Eric (one of the authors) eric(a)mixadlive.com?

Broken Links and Orphan Checking
by Darin Lee 11 Aug '00

11 Aug '00

Greetings, Is there any way within Zope to parse HTML to look for broken links and orphaned files? The site I am building will have many Zope dynamic componants, but also a good share of wrapped static HTML pages maintained by content contributors in Frontpage/Dreamweaver. I know that orphaned files and broken links *will* become a problem over time. Does anyone know of a good way to handle this? Thanks, -Darin M. Lee Darin M.
