WebDrive vs Zope?
by Wolfgang Strobl 07 Mar '01

07 Mar '01

While reading chapter 3 of Dieter Maurers "Building Dynamic WebSites with Zope" (a fine piece of work, btw!), I followed the reference to WebDrive (a product mapping anything accessible by ftp or by webdav to drive letters, i.e. into the file system on windows) and gave it a try. ftp works reasonably well with Zope, but I couldn't get the webdav support (i was looking for) to work. It connects successfully. but displays an empty drive, afterwards. I can create documents there (which indeed arrive intact in Zope), but that's it - there is no way to see any of the existing files or folders at all! This behaviour is independent of whether I log in using an id with manager rights or anonymously. In the latter case, I can't create any files, of coures. Before digging deeper into it, I'd like to ask whether any of you has any hints. As it seems, it works for some people. Tres Seaver recommended WebDrive in http://groups.yahoo.com/group/zope/message/51235 for example. (I'm using WebDrive 3.0 with a almost fresh Zope 2.3.1b1 installation on win2000, btw.) -- ws

From POST to GET
by Peter Bengtsson 07 Mar '01

07 Mar '01

Problem is this. I POST a form to a page called process_html. Inside process I do some validation on posted variables. If i find that something is wrong I want to complain by sending the user to bad_input_html?errmsg=Username%20Empty (which is a GET request in theory). What happens is that the redirect is a mix of GET and POST. It is a pure POST request, but the querystring is picked up as well. Truth is that this works fine in Internet Explorer, but it fails on the UK Vodafone WAP Gateway. It works on all other WAP Gateways except this one. This tag would work in a normal situation: <form action="process_html?loginname=Peter%20Bengtsson" method=POST> But with my gateway only the POST variables are sent and the variable "loginname" is ignored. Anyhow. How do I "leave" the POST requesting and break out of it to do a GET request?? Is there a header I can set? <pseudo code> <dtml-call "RESPONSE.setHeader('REQUEST_METHOD: GET')"> </pseudo code> Any smart suggestions more than welcome! Peter

RE: [Zope] Getting client browser type
by Etienne Labuschagne 07 Mar '01

07 Mar '01

Unfortunately I need to have some JavaScrapt (intentional sp) in my website. Just about every browser have it's own implementation of this language so one ends up writing a script for every browser (YUK!). I don't want to check this in JavaScript and use ifs to decide what code to use as a lot of code is then downloaded to the client that his browser never use. My idea is to have scripts for every browser (where they differ) and just send the correct script to the client. So, the decision which script to send must be made by Zope. I can use JavaScript itself to check what the browser is, but when I know, how do I tell Zope that? Unfortunately I cannot do without JavaScript.

Please dont this information for such sites that tell you: "Go away and get this ... specific browser!" Did you ask why almost all browsers nowadays call themself "Mozilla" ? ;) Regards Tino

Add a Document from an existing File
by Steffen Bergmann 07 Mar '01

07 Mar '01

Does anybody know how to add an DTML Document with uploading the contents from a local File on the filesystem. I need to do this in DTML Code (or Python?) and not in the managementscreen. The Code: <dtml-call "manage_addDTMLDocument('id','title','datei.html')"> only adds a Document with the contents 'datei.html'. Is there any other option to do something like this? Steffen

<dtml-in item> iteration on INSERT method
by Paz 07 Mar '01

07 Mar '01

Hi all, I've used the <dtml-in item> iteration many times with dbms tables and ZSQL methods, but always in context of an UPDATE table SET where clause. This works because the iteration is selective to a certain value that is set from the html page at POST or the form. What I WANT to do now is INSERT into table using the same item construction, when a checkbox in a multiple record form is checked. I can see in the REQUEST.form that only certain values are present, but I cannot be selective of this in the ZSQL method to add the records. Here is what I have for the ZSQL method: <dtml-in item> insert into lpref (uid, linkid, hiearchy) values ( <dtml-sqlvar uid type=string>, <dtml-sqlvar linkid type=int>, 0 ) <dtml-var sql_delimiter> </dtml-in> What happens is that ALL items on the form go into the DB because the item construction does not care if the checkbox is checked or not. What I'd like is a WHERE clause tacked to the end, but this doesnt seem to work. Dont think and INSERT INTO table WHERE is valid.... but will have to dig the MySQL refs. Another thing I could do is query the checkbox value inside the iteration, but it doesnt work because I think that Item wraps itself in a way that I cant address it properly. Such as: <dtml-in item> <dtml-if "favLink"> insert into lpref (uid, linkid, hiearchy) values ( <dtml-sqlvar uid type=string>, <dtml-sqlvar linkid type=int>, 0 ) </dtml-if> <dtml-var sql_delimiter> </dtml-in> But I get an attribute error.... Can anyone offer me a suggestion? Thanks as always, Paz

SQLTEST is case insensitive?
by The Doctor What 07 Mar '01

07 Mar '01

I have the following ZSQL method: SELECT "URL"."ID", "val_Protocol"."Protocol", "URL", "URL"."Name", "URL"."Description", "URL"."Created" FROM "URL", "val_Protocol" <dtml-sqlgroup where> <dtml-sqltest ID type=int optional> <dtml-and> "val_Protocol"."ID" = "URL"."val_ProtocolID" </dtml-sqlgroup> When I set ID equal to 1 (to test) I get this back: Error, psycopg.ProgrammingError: ERROR: Attribute 'id' not found SELECT "URL"."ID", "val_Protocol"."Protocol", "URL", "URL"."Name", "URL"."Description", "URL"."Created" FROM "URL", "val_Protocol" where (ID = 1 and "val_Protocol"."ID" = "URL"."val_ProtocolID" ) The problem is two fold: 1) ID = 1 should be "ID" = 1 so that PostgreSQL will treat it as a case sensitive string. 2) ID = 1 should really be "URL"."ID", but I can't figure out how to pass that through sqltest! Any help is appreciated.... I have tried this with a zpopyda and zope-psycopgda, neither worked. And, no, using 'as' to rename the select to lowercase _does not_ work. Ciao! -- "Clothes make the man.
