Gadfly
by Nemeth Miklos 04 Jan '00

04 Jan '00

The Gadfly shipped with Zope is really useful only for demo purposes, what to do if I want to use Gadfly for production (in a real life ecommerce application) purposes (storing business data, SQLSession's data)? This text is shown by Zope: "The Zope Gadfly product is a free Zope database adapter intended for demonstration purposes only. It is only suitable for learning about Zope SQL Methods. Database operations are performed in memory, so it should not be used to create large databases. This installation is using a non-optimized version of Gadfly and should not be used to assess the performance of either Gadfly or Zope." NM

inheritance question
by Timothy Wilson 04 Jan '00

04 Jan '00

My site has a folder structure like this: / (Zope root) /Images /folder1 /etc There's a method in / that uses images from /Images utilizing the <dtml-with Images><dtml-var image_foo></dtml-with> syntax. When I call that method from inside /folder1, however, I get an error. I assume there's a slick way to make this work. Is this a namespace issue? I'm still working on understanding that.

However, you can lever the REQUEST object for this kind of thing: <dtml-call "REQUEST.set('Size', 'big')"> <dtml-call "REQUEST.set('Size', 'bi')"> <dtml-if "Size=='big'"><h1></dtml-if> Hello. <dtml-if "Size=='big'"></h1></dtml-if> Now, 'Size' is found in the REQUEST object, and there the value of 'Size' can be modified. -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

Two things wrong here. First, the Size variable is only visible within the scope of the let tag, so you'll have to close it _after_ the block in which you want to use it. Secondly, what comes after the = sign in the let tag, is either a Zope name (same as in <dtml-var name="xxx">), when you don't use quotes, or a python expression (same as in <dtml-var expr="xxx">) when you do use quotes. In your case, "Size='big'" is interpreted as "Size equals the python expression big", where "the python expression big" means the value of the variable named big. There's your Key Error. In order to assign the string literal 'big' to the variable Size, you'll have to use quotes around the word big, either Size='"big"', or (confirming to the official HTML way of quoting) Size="'big'". With above corrections, you're code should read: <dtml-var standard_html_header> <dtml-let Size="'big'"> <dtml-if "Size=='big'"><h1></dtml-if> Hello. <dtml-if "Size=='big'"></h1></dtml-if> </dtml-let> <dtml-var standard_html_footer> -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

Jephte CLAIN has released the following products: - jcNTUserFolder, a product that authenticates users on a NT Domain. The main difference with htrd's product is that roles are given through the web, and impersonation is not used. BEWARE. This is beta for now. Please send you comments - MIMETag patch that add features to the mime tag. - WebImport patch to import files through the web. Following soon: - How to use Zope and IIS together in REMOTE USER mode.

Gennerally, IE is very precise at interpreting the HTTP standard. It is quite probable that your app has an error somewhere that Netscape glosses over. One way to you could diagnose this, is by using a HTTP tracer like TracePlus32 Web Detective (a demo can be downloaded from http://www.sstinc.com/) which will show you exactly what Netscape and Explorer send over the wire, and what answers Zope gives. This is much easier than using a telnet session and typing in your HTTP requests manually. It should at least show you what faulty requests IE sends, and from there interpret how IE comes to the conclusion it should send those requests.
