Acquisition inquisition
by Ben Glazer 23 Sep '99

23 Sep '99

I appear to misunderstand how acquisition works in Zope, as it's not behaving like I expect it should. This is what my folder structure looks like in Zope: / + test + education Both / and test contain DTML methods called standard_html_header. A file in /test/education contains the following line: <dtml-var standard_html_header> This causes the header in / to be used, and not the one in /test. I thought that methods were acquired from containers. Since /test contains education more immediately than / contains /test/education, why does a DTML method in /test/education seem to default to acquiring methods from / ? Thanks, Ben

<dtml-var REQUEST.get('BODY','')>

What is wrong with this bit here? <dtml-var standard_html_header > <dtml-var REQUEST.get('BODY','') > <dtml-var standard_html_footer > Why is it I can't display the body of a HTTP Request? I have also tried, <dtml-var "REQUEST.get('BODY','')" > but still got nothing.

I'm not getting my digest, and can't seem to get to the mailman pages on either the "new" site or the "old" one at port 8080. Am I nuts? -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

Re: [Zope] ZServer Only

This may not be as simple as it seems at first glance (for a zope/linux newbie). Changing the port in the httpd.config file from 80 to 8081 (as root) and then rebooting activates Apache on port 8081 but it also continues to serve on port 80. Trying to start Zserver on port 80 under those conditions generates an error. Any advice on how to run Apache on a port other than 80 simultaneously with Zserver on port 80?

Just to hear the fullfilling bleep of the BIOS completing its initialization, I assume, because beyond that there's not much point in rebooting a Linux machine. <wink> -- Alexander Staubo http://www.mop.no/~alex/ "He could open a tin of sardines with his teeth, strike a Swan Vestas on his chin, rope steers, drive a steam locomotive and hum all the works of Gilbert and Sullivan without becoming confused or breaking down in tears." --Robert Rankin, _The Book of Ultimate Truths_

Before I think too long about creating this myself, is there a Collector type product out there already so that I can keep track of bugs/jobs related to my Zope application? All my best, -- Jason Spisak webmaster(a)hiretechs.com

SQL queries with LIKE???? (Am I to dumb?)

Hi, I like to create a SQL Method that does a query like select * from account_info where account like "%foobar%" But I only get equality tests or a query that looks like that select * from account_info where account like "%'foobar'%" I think, that this is easy but I can't see the solution for this?

Single item list
by Jason Spisak 22 Sep '99

22 Sep '99

Zope-o-rama's I have a list object called 'things', and sometimes it only has one object in it.  <!-#var sequence-item-->  returns ['my_list_item'], instead of my_list_item. How can I strip the [', '], off either end? All my best, -- Jason Spisak webmaster(a)hiretechs.com

Authentication and Zope
by davidbro＠namshub.org 22 Sep '99

22 Sep '99

I am using authentication to do something similar to the "Edit This Page" functionality that Dave Winer et al have done with the Frontier newsgroups. Now the vast majority of it is simple -- I use this DTML snippet on my front page (/zope/personalWebLog): <dtml-if "AUTHENTICATED_USER.has_role('Manager')"> Hello, <dtml-var AUTHENTICATED_USER>. You may <a href="/zope/manage">edit</a>. <dtml-else> <form action="login" method="post"> <input type="submit" name="submit" value="login"> <input type="hidden" name="redirect" value="/zope/personalWebLog"> </form> </dtml-if> which references a dtml method called "login" which contains: <dtml-call "RESPONSE.redirect(_['redirect'])"> ...and I massage the permissions on "login" so that it forces the user to provide authentication information via the standard username/password dialog that browsers use. It _mostly_ works as intended. If the person connecting to the web page isn't a manager, they get a "login" button. If they are, they get a greeting and a quick link to the Zope management screen. I'm running Zope at home, and it all works fine if I'm connecting from work. I hit the login button, it prompts for my username and password, and redirects back to my main page, displaying the nice greeting and the link. However, when I try to login from home, it displays the dialog fine, and I supply the right username and password, but when it redirects, it goes back to the page with the "login" button. Strangely enough, if I type the "manage" URL manually, it goes right in without prompting for a username and password, so obviously the authentication tokens are getting passed properly. And when I return to the page _after_ going to the management screen, it displays the greeting and the link. I used to think I had a clue about Zope Zen, no I'm not so sure. Particulars: Zope is running on a Linux machine at home, and I'm also using Linux at work, and using Netscape Navigator 4.61 to connect to the web page, at hame and at work. And I'm using Zope 2.0.1. I thought this was a caching problem, but it shows up even after I clear the cache. dave (pleading for enlightenment)
