Hi *,
I am using nevow 0.1 so if this has been fixed/is a know problem just redirect me to the right resource.
Apparently it is possible to serve a Page instance from a render_XXX method if it is implemented as a rend.stan docFactory but not if it tries to load a template from disk (rend.htmlfile). i.e., the following code (add some imports, etc.) works [...]
Nevow 0.1 is very _very_ outdated. I'd recommend using SVN trunk instead, and if you want stability, just don't update unless you encounter bugs (like now :)
using trunk and branches/freeform-patterned (after irc session with fzZzy) right now.
Being able to return pages from render_ methods is (should be) fully supported in SVN trunk.
it is not; here are the problems: trunk: stan -> works as expected htmlfile -> infinite recursion xmlfile -> no error but does not render (template copied 'as is' to output) branch: stan -> works as expected htmlfile -> works as expected xmlfile -> no error but does not render (template copied 'as is' to output) i can check the other loader if needed. a test case is on the way.
You can even go a step further and denote a specific part of the doc factory which should be used for this:
class SomePage(rend.Page): docFactory = rend.htmlstr(''' <html><body> <h1>Header</h1> <div nevow:pattern="content">Content</div> </body></html> ''')
If this object is rendered as a page, the header will show up. But if you return it from a render_ method, then only the div with the "content" pattern (and everything inside it) will be used. So you can create pages with all the necessary fluff around the edges, but avoid rendering the "skin" (headers, navbars, what have you) multiple times.
I don't find this much usefull, sorry. what we really need in a real use-case (on your browser in 15 days and GPL'ed after that :) is sub-template rendering. luckily enough loaders.htmlfile is working. hope to see that in trunk (and maybe a working xmlfile too) soon. federico -- Federico Di Gregorio http://people.initd.org/fog Debian GNU/Linux Developer fog@debian.org INIT.D Developer fog@initd.org We are all dust, Saqi, so play the lute We are all wind, Saqi, so bring wine. -- Omar Khayam
