converting < to < problem in page templates with Javascript
by Mark Lilly 09 May '02

09 May '02

Hi, I am trying to import into a page template a Javascript File. I use this: <script tal:content="nocall:root/CT/Scripts/J_Scripts/calendar.js">hold</script> I get the same text without the nocall expression. That file is brought into the template, except that in the Javascript code, all the '<' and '>' are converted to < and > This damages the Javascript code. For example, the following line of javascript is changed original:->> for(var i=0; i<3; i++) changed:->> for(var i=0; i<3; i++) Notice, in the changed version, there are 3 semicolons (' ; ') instead of 2, and the Javascript parser in the browser throws an error. Can i bring the text from the javascript file in Exactly as it is? I can make it work in DTML like this, but want to use ZPT. <script> <dtml-var calendar.js> </script> Thanks, mark

Why is it so hard to do simple things?
by John Adams 08 May '02

08 May '02

I'm new to Zope, and new to Python, but certainly not new to software engineering, with most of my background in C, Perl and Java. I'm trying to do something quite simple. I'd like to see if a user has checked off a radio box. If it's their first time to the page, then the attribute request.perm_or_temp hasn't been set, and one of the boxes should be checked by default. If it's their 2nd time to the page (perhaps an error, and they're POSTing again) then I'd like to retain the state of the checkbox. If I was doing this in perl it'd be quite easy; I could check the query variable, and act on it -- but now I have to deal with things like not being able to even examine the variable without throwing an exception, and the fact that Python doesn't short-circuit blows. i.e. You can't examine something like: if (hasattr(request,'perm_or_temp') and request.perm_or_temp == 'P') ... In Zope, I assume that I should be using DTML here, and perhaps dtml-in over the items in the radio list. What's the proper way to do this zope? My current version is quite poor, takes up too many lines, and is disgustingly inefficient: (this is a dtml-method) # Default block -- this is a really shitty way to do this sort # of thing. I hate python. if not hasattr(request,'perm_or_temp'): print "<INPUT TYPE='RADIO' NAME=perm_or_temp VALUE='P' CHECKED> Permanent" print "<INPUT TYPE='RADIO' NAME=perm_or_temp VALUE='T'> Temporary" return printed # else we have it, process the request print "<INPUT TYPE='RADIO' NAME=perm_or_temp VALUE='P'>" if request.perm_or_temp == 'P'): print "CHECKED" print "> Permanent" print "<INPUT TYPE='RADIO' NAME=perm_or_temp VALUE='T'>" if request.perm_or_temp == 'T': print "CHECKED" print "> Temporary" return printed ---- Thanks. --john

Setting multiple cookies?
by Michael 08 May '02

08 May '02

I am trying to set two cookies and only the first one gets set. I'm doing: <dtml-call "RESPONSE.setCookie('some_value', some_value)"> <dtml-call "RESPONSE.setCookie('another_value', another_value)"> In every case, the first cookie is set and the second is ignored, am I missing something here?

dtml-let and python script
by Kevin Lewandowski 08 May '02

08 May '02

Maybe this is really easy but I can find an example anywhere. How can I access a variable set with "dtml-let" inside of a python script? For example: <dtml-let val="'a value'"> <dtml-var python_script> </dtml-let> How can I access val from inside python_script? thanks -Kevin __________________________________________________ Do You Yahoo!?

How to check type of variable in DTML
by Schmidt, Allen J. 08 May '02

08 May '02

I am passing a variable to a ZSQL method and I need to check whether its a string or a list before it is part of a WHERE statement. How can I check this? <dtml-if mk> CMAKE IN ( <dtml-var "mk[1:-1}"> ) </dtml-if> This works well if its a list but blows up if just a string. Needs to be like this: <dtml-if mk is_A_list> CMAKE IN ( <dtml-var "mk[1:-1}"> ) <dtml-else> <dtml-var sqltest mk column=CMAKE type=nb optional> </dtml-if> Thanks -Allen

Re: [Zope] [ANSWER] 500 error with IE on login

Re. returning a 500 status on an authentication error, which makes the login screen invisible to MSIE users on windows: >On Tue, May 07, 2002 at 12:41:56PM -0400, SOMEBODY wrote: >>I strongly oppose modifying a properly functionng, RFC-conforming >>product to coddle a non-informative and non-RFC-conforming product. >>Fix the broken product, not the working one. (Please note that the quote above was a followup to my message and it was not what I said! ) If I was making a tool/product only for myself, my team or something like that I would fully concur. This is not the case for most zope users. a) If zope is used to support a publically-acessible site it absolutely must work in a manner that makes it convenient and acceptable for MSIE/Windows users: I take it that's not debatable. Since I never user MSIE/Win myself I had a hell of a time figuring out the 500-error bug (blaming it on networking issues and such). This is not a good state of affairs. While i don't like it, MSIE/Win is a de facto standard. (I know this is flame bait... you know what I mean, I feel sick for saying it, so please let's not get into it.) The hard-nosed "don't fix a conforming product line" if taken too strongly it the kind of attitude that could really be bad for zope acceptance. b) It seems that semantically a "server error" (500) code isn't even the right code for this particular problem, so the fix is fine there (although I have not checked the RFC). c) The worse issue is what to do with the other unexpected cases where zope might generate a 500 error as it's a default exception code. On my zope, I want the user to see the message page, if any. Inserting code to detected the browser/system and only change a 500 to a 200 code for MSIE/Win users alone seems fine but I'm not gonna bother doing this myself right now, in particular 'cause I don't know how robust it would be. d) As an aside, does any other browser ever really care about these codes?

LDAPUserFolder and Zope 2.5.1
by Josef Meile 08 May '02

08 May '02

As I know, LDAP it's a standard protocol to access a user database on a server. I also read that by using LDAP you can read and write on this database. In my case, I only have read permissions and I'm not allowed to see the database internal structure neither to change it. I've tried to get it work but it doesn't and don't know why. I Just create a schema as follows: LDAP Server: ldap.myorganization.ch Login name attribute: uid RDN Attribute: Canonical name Users base DN: ou=student,o=myorganization,c=ch Scope: Subtree Group storage: Groups not stored on LDAP server Groups Base DN: same as Users base DN (I don't know what else can I put here and I don't have more info) LDAPLogin and Pasword are empty User object classes: top,person User password encryption: crypt Default User Roles: Anonymous Authentication: Basic HTTP Authentication Next I added the group student and assigned it my local Zope role Student. My question is how can I populate my user folder? I saw the feature add user, but I need to add 500 hundred users and I guess this is not the way of doing it and I don't see anythin on the Caches tab. My logic says my that this feature is only if you want to add users to your ldap database. But I rather than add want to authenticate them. Because I don't have any result when I search by uid, I just made this: <dtml-in "findUser('sn','lastname')"> <dtml-var "_['sequence-item']"> </dtml-in> And then I saw a dictionary with lots of fields, but not uid. I'm just wondering why. I guess the authentication looks for this username and then gives the password. Whenever I observe the log contents, I see always somethin like: (9) Apr 29 20:37:55: userx not found (getUser) Does anybody know what I'm doing wrong? Thanks in advanced, Josef.

path to argument rewrite
by Russell Uman 08 May '02

08 May '02

howdy. i'm writing a zope page that generates dynamic content based on the query string in the URL. for example: http://index_html?content=introduction is different from http://index.html?content=contact some search engines have trouble indexing pages by query strings. a common way around this is to use a path instead of a query string in the URL and rewrite the path as a query string. so: http://index_html/content/introduction is rewritten as http://index_html?content=introduction by the webserver. i know how to use a rewrite rule in apache to do this. i've heard that this is doable in Zope. but i can't find any documentation on how to do this. can anyone help? thanks!
