Newbie question: graphics in subdirs
by Randy Edwards 07 Jun '00

07 Jun '00

I'm going to rewrite my web site in dtml and am using the latest stable Zope. Well, I should say I'll rewrite it after I get over this infuriating newbie problem I have. :-) ` I'm trying to get Zope to display an image from a subdir. I've whipped up a simple dtml document called "test". Test contains this: <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p>This is the <dtml-var id> Document.</p> <p>Now show a graphic: <br> <dtml-var logo.jpg> </p> <dtml-var standard_html_footer> That references an image file in the root directory called logo.jpg. Everything works, it displays fine. However, I want to keep all of my commonly used image files in a subdirectory called /images. So I create a folder called "images", upload another copy of logo.jpg into it, everything's fine. I change the dtml in the "test" document to be "<dtml-var /images/logo.jpg>". And it doesn't work, giving me an error message of: Error Type: KeyError Error Value: /images/logo.jpg Looking through the docs and tutorials I can't find anything on this -- and I know it's mindlessly simple. Can someone whack me with a clue-bat?

Restart your service and your set. Alternatively you might tweak the registry at key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<yourZopename> \Parameters\start with the -p switch. But the first is easier i'd think ;-) Also see: http://zdp.zope.org/projects/zbook/book/VII/PlatformInstallation/InstallDraf ts/instwindraft3/

accessing lists from dtml
by mikk 07 Jun '00

07 Jun '00

Hello all, If I have a REQUEST variable that equals a list, like this: ['ITEM_NUMBER','PRICE'] How would I get ITEM_NUMBER and PRICE into separate variables? The following code gives me a screen full of the appropriate values (using an external method), but I can't figure out how to use the results: <dtml-in "parseCSV()"> <dtml-var sequence-item><BR> </dtml-in> Displays: ['003020','149.95'] ['003021','79.99'] .. .. ..

Re-posting a form
by Paul Gresham 07 Jun '00

07 Jun '00

Hi, I have two cases where I have a user in Zope and capture information from them, then need to re-post the data to another page. One case is I am using WorldPilot and have customized it to have many instances of it, segregating users into individual companies (a bit like hot office). I have different instances of WorldPilot and attempt to jump to that instance from a logon screen as such Company: User: Password: The instance of WorldPilot is named the same as Company: (self.REQUEST['Company']) and the user becomes user.company(a)mydomain.com. I have no problems with getting the objects, calling the worldpilot object correctly and passing in my REQUEST object, however there seems to be some problem with redirection, or setting the base url. I have tried setting this with REQUEST['RESPONSE'].setBase but with no luck. It seems like I need to redirect the browser to the correct URL for this to work, but then I lose my REQUEST object! Does anyone have any ideas, I think I'm lacking some understanding of the HTTP protocol, and getting myself deeper and deeper into a mess ! The other case is where I actually have to read the information from a form and then perform a HTTP POST to cgi program which handles my email admin. I'd appreciate any pointers on how to get Python/Zope to perform a HTTP POST to an external program. Many Thanks Gresh

Re: import-export

Ok, after poking around in the code and debug (!) I finally realized that the ID being passed to manage_exportObject is not the filename, but the id of the object to export. So a couple of examples to clarify: to export a folder from the top level (root), you can do two things: 1. Check the checkbox and click the Export... button near the bottom of the screen. This will open the import/export form with the id already filled in. Simply click Export. 2. Click import/export at the top of the screen and type the name of the Folder (or other object) you wish to export, then click Export. You should recieve some positive confirmation telling you the filename. This will create a file called var/ObjectName.zexp (ObjectName being the name of the folder or object you chose) So how do I export everything from root? Ok .. this is a real bugger, I can't believe it's taken me so long to figure it out (I was first checking file permissions etc). Answer: Make sure you are in the root folder and then click the Export... button near the bottom of the screen. LEAVE THE ID BLANK and click Export. Again a positive confirmation will appear telling you have just created a file var/.zexp - of course I don't need to remind you (but I will) that the .zexp file will be hidden on Unix machines as are all . prefixed files. I think that is hardly intuitive but doesn't seem to cause too many problems as I couldn't find any posts about it .. Has this just happened in a recent release, I know some workings to do with XML Exports were added?? The help text on the import/export form reads "You can export Zope objects to a file in order to transfer them to a different Zope installation. You can either choose to download the export file to your local machine, or save it in the "var" directory of your Zope installation on the server." I think this is very misleading and recommend changing it.
