Garry Saddington, on 2007-07-12: I am trying to use html2pdf and htmldoc to generate pdfs on the fly. I can get it to work perfectly if I set all view permissions for anonymous. However, this is not suitable for a member only site. Can anyone point me in the right direction for such use? I am using: (Zope 2.9.0, python 2.4.2, win32) and latest version of html2pdf.

Then report back here with any errors you get. In the html2pdf howto at Zope it says 'Only works with anonymous permissions' -- just read it properly!. Probably because the htmldoc process accesses the web page via a URL passed to it by html2pdf. So I guess I will have to pass the rendered page to the script and hence to htmldoc. When I use it now all I get is a nice PDF of the cookiecrumbler login screen and no error messages in the error_log. Thanks for replying, am I on the right lines?

My experience with htmldoc is that it does work for non-anonymous HTML documents, provided that either (1) there are no images in the document, or (2) any images in the document are visible to anonymous and the image 'src' attributes specify the absolute URL of the image. I strongly suspect that this is because the HTML is handed directly to the htmldoc tool, and then htmldoc tries to access the images from you server. It can't log in, hence the images must be anonymous. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

RE: [Zope] RE: html2pdf truncating html content
Refinement of problem statement: The DTML file on which html2pdf is called is populated by a python script which builds and returns html by processing a list of objects in a for loop.

Re: [Zope] RE: html2pdf truncating html content
Just a wag (wild assed guess)... in your BODY loop, if d.title is null could you be embedding a 'null' char in the text string, which may cause html2pdf to choke?

Re: [Zope] RE: html2pdf truncating html content
some more wags: 1) remove the html comments from the generated html code (ie. get rid of the !-- PAGE BREAK -- tags) 2) remove the body loop and hard code in a 1 liner insteadeg. body +='some new text' and see what happens 3) where are the html and /html tags added into the html code you pass to html2pdf?
