The preferred test would be something like:: <dtml-if "SecurityCheckPermission( 'Edit Foo', this() )"> <a href="&dtml-absolute_url;/&dtml-type;edit">edit this</a><hr> </dtml-if> Note as well that, if the user has not yet authenticated, suppressing the display of a link which would trigger authentication (if the edit method is guarded, as it should be, by the same "Edit Foo" permission) can leave that user in a Catch-22: they aren't authenticated, and they can't trigger authentication!

Site search with squishdot and own products
by Anders Holmbech Nielsen 05 Oct '00

05 Oct '00

Hi, I'm having a "small" problem here. I would like to have a site search that searches everything within a directoty on the Zope server. I'm only using the ZODB but I have two Squishdot's installed and several ZClasses which is indexed in a catalog. How do I approach this problem ? Is there a Zopish/dtml/catalog way or is it the dirty way ? Thanks in advance Anders Nielsen System Developer

In a python method, I want to convert a XML string into a dictionary...
by Frederic Quin 05 Oct '00

05 Oct '00

Hi all, I would like to create a python method which take a parameter xml_string and return a dictionary containing all tags, values and attributes. I know that it exists some modules for xml conversions but I don't know very much how to use them. I am novice in Python so it's a little bite difficult for me to understand the codes... Thanks Fred

Newbie with little questions about Zope
by Antonio Navarro Navarro 05 Oct '00

05 Oct '00

Hi All ! I am a newbie in the Zope world. I've benn working several years with IIS, Apache, Perl, ASP, PHP, etc.. in Windows and Unix environments, and want to try Zope, but have some questions about it. 1.- Can I made virtual hosts (www.domain1.com, www.domain2.com, and so on) using the Zope web server, or must I use Apache and install pcgi ? 2.- Where can I find information about running Zope + Zserver + Php + PostgreSQL under Linux ? 3.- I have installed Zope from the rpms and works fine, but I'm unable to change the HTTP port from 8080 to 80. When I made the change and then restart Zope, I can see during a few seconds two processes running with the new port (-w 80) but after a few seconds the server stpos.

Problem with <DTML-CALL>
by Tim Gildersleeve 05 Oct '00

05 Oct '00

Hi I am trying to get a <DTML-CALL..... to work, but am having a strange problem. The line is <dtml-call "REQUEST.set('TOTALDEVIATION',fSTART)"> I am trying to create a variable called TOTALDEVIATION and assign the value of fSTART (passed through the documents POST or GET value). If I do <dtml-call "REQUEST.set('TOTALDEVIATION',0)"> there is no problem, but with the first one, i get Error Type: TypeError Error Value: number coercion failed Now, I am assuming (I could be wrong) that this is a problem with the type of the variable - it needs to handle floating point numbers such as 1.25 or 5.75 etc. Anyone have any idea - this has really got me stumpped. Please reply to tim(a)otcs-online.net as well as the list as I dont get the time to search through the list every day. Cheers Tim Gildersleeve tim(a)otcs-online.net

Re: [Zope] IMAP and Zope!
by Joachim Werner 05 Oct '00

05 Oct '00

Thanks for the input I got! Just a small wrap-up of what I learned: - The NotMail and old IMAP Adapter code don't seem to be seriously used by anybody - WorldPilot could be a solution, but it only if it was more modular. Ryan Hughes promised to integrate it into Zope by release 2 (incl. a ZODB-based document storage - There is a similar project by Morten W. Petersen that also will feature a ZODB-based message storage that will be searchable, Catalog-aware etc. Joachim. -- Iuveno - Smart Communication Joachim Werner _________________________________________ Marie-Curie-Straße 6 85055 Ingolstadt Tel.: +49 841/90 14-325 (Fax -322) Mobil: +49 179/39 60 327 E-Mail: joachim.werner@iuveno.de/joachim.werner@iuveno-net.de WWW: www.iuveno.de/www.iuveno-net.de ------------------------------------------------------- -- Iuveno - Smart Communication Joachim Werner _________________________________________ Marie-Curie-Straße 6 85055 Ingolstadt Tel.: +49 841/90 14-325 (Fax -322) Mobil: +49 179/39 60 327 E-Mail: joachim.werner@iuveno.de/joachim.werner@iuveno-net.de WWW: www.iuveno.de/www.iuveno-net.de

_ in a product
by Pierre-Julien Grizel 05 Oct '00

05 Oct '00

Hi, Correcting my earlier post, I'd "simply" like to have a way to get the _ (namespace) variable in a product method. Currently, I use the following syntax : <dtml-var "product.method (_, 'Hello, world !')"> to pass _ to my product. It works, but..... Reminds me of the great times when my hammer was the dtml-method...... Has anyone a way to acquire _ in a product without constrainging the user to pass it explicitly ?????? blub-blub-blub-blub...... P.-J. -- If the only tool you have is a hammer, you tend to see every problem as a nail. Si le seul outil dont vous disposez est un marteau, vous avez tendance à voir chaque problème comme un clou. --Abraham Maslow
